Fictional Characters Wiki

Sonic the Hedgehog (ソック・ザ・ヘッジホッグ Sonikku za Hejjihoggu?) is the title character and main protagonist of the Sonic the Hedgehog series and Sega's mascot. He is a fifteen-year-old anthropomorphic hedgehog gifted with the ability to run at the speed of sound and beyond, hence his name, and possesses lightning fast reflexes to match. As his species implies, Sonic can also roll up into a concussive ball, primarily to attack enemies.

Ever since stepping into the battle against injustice, Sonic has been the champion of peace and is renowned the world over for saving it countless times. During his many adventures, Sonic has traveled from the ends of the world to the far reaches of space and time, while facing countless trials that have tested him to the fullest, earning him many titles, allies and the scorns of several foes. Well-known for his legendary cocky attitude, easy-going demeanor and somewhat short temper, yet strong sense of justice, compassion, and love for freedom and adventure, Sonic uses his abilities to protect the innocent from his world and those beyond from the forces of evil, especially his arch-nemesis Dr. Eggman, who constantly seeks world domination.

Sonic has been acknowledged as, undoubtedly, the most recognizable and famous character in the Sonic the Hedgehog franchise according to an official popularity poll in 2011.

Concept and creation

While several people have been involved in the creation of Sonic, the artist Naoto Ōshima, programmer Yuji Naka and designer Hirokazu Yasuhara are generally credited with the creation of the character.

In April 1990, Sega requested a game capable of selling more than 1,000,000 copies; a character who could compete against Nintendo's Super Mario, and a character to replace Alex Kidd as the company's mascot. Several character designs were submitted by its AM8 research and development department. These included an armadillo (who was later developed into Mighty the Armadillo), a dog, a Theodore Roosevelt look-alike in pajamas (who was later used as the basis of the design of the main antagonist Dr. Eggman) and a rabbit (who would use its extendable ears to collect objects, an idea that was later used for a separate Sega character, Ristar).[7][8] Eventually, the mascot they selected was Naoto Ōshima's submission, a spiky teal hedgehog code named "Mr. Needlemouse", later renamed Sonic.[9] Sonic's color was based on the Sega logo, his shoe buckles based on Michael Jackson, his shoe color based on Santa Claus, and his personality was inspired by future-President Bill Clinton's "get it done" attitude, who Ōhshima felt embodied a modern sensibility of wanting to get things done right away, righting wrongs as they presented themselves instead of letting them linger.[7][10][11][12] According to Yuji Naka, Sonic's color also serves to symbolize peace, trust, and coolness which are the attributes of Sonic's character. His trademark speed is based on Super Mario Bros. World 1-1, with Sonic creator Yuji Naka stating in issue 260 of Nintendo Power that"I always tried to get through the level as fast as I could," which inspired the initial concept for Sonic the Hedgehog. Sonic was created without the ability to swim because of a mistaken assumption by Yuji Naka that all hedgehogs could not do so.[13]

A group of fifteen started working on Sonic the Hedgehog and renamed themselves Sonic Team. The game's soundtrack was composed by Masato Nakamura of the band Dreams Come True. Sega sponsored the group's "Wonder 3" tour, painting Sonic on the tour bus, distributing pamphlets advertising the game, and having footage of the game broadcast above stage prior to its release.[14]

The original concepts gave Sonic fangs and put him in a band with a human girlfriend named Madonna. However, a team from Sega of America, led by Madeline Schroeder,[7] "softened" the character up for an American audience by removing these elements. This sparked a heated issue with Sonic Team. Naka later admitted that it was probably for the best.[7] Sonic's precise age, weight, height and other physical characteristics vary depending on the continuity in which he appears and the style in which he is drawn. In the video games, Sonic's original design by Naoto Ōshima was with short spikes, a round body, and no visible irises. Artwork featuring this design and drawn by Akira Watanabe was displayed on the package artwork forSonic the Hedgehog (1991), and most subsequent Sonic video games featured similar designs.[15] When Sonic the Hedgehog 2 for the Mega Drive appeared, Sonic's proportions changed. The original 1:2 head to height ratio changed to 1:2.5.[15]

Beginning with Sonic Adventure in 1998, Sonic was redesigned by Yuji Uekawa as a fifteen-year-old character, with longer legs and a less spherical body, longer and more drooping spikes, and emerald-green-colored eyes. Further subtle changes to the character's design have been made in subsequent games. Spin-off media such as comics and cartoons have featured variations on all these video game designs, with restrictions set by the standardized model sheets.


Sonic is an anthropomorphic hedgehog with blue fur that covers most of his body, peach skin that covers his arms, muzzle and torso, and emerald green eyes. He has six head quills dropping back from the back of his head, two quills protruding from his back drooping downward and a short tail that points up.

He wears two light-weight, hyper friction resistant red sneakers with a white strap, cuffs and a gold buckle, a pair of white leather gloves (similar to that of Mickey Mouse's) with sock-like cuffs on his hands.


See Sonic the Hedgehog/History


Sonic has been described as being "like the wind"; a drifter that is always on the move and is noted for being free-spirited and adventurous. He values freedom above all else and lives his life according to his own rules rather than the standards of those around him and without concern for what others think, and enjoys nothing more than traveling the world. Endowed with a strong passion for life, he is never in one place for long and always moves forward to look for his next challenge, making his life a never-ending series of adventures. Because of his need for freedom, Sonic loathes the idea of being constrained, as he gets extremely impatient and uneasy when cooped up or when being forced to stand in one place.

Sonic is most of the time easy-going, cool and care-free. However, he never second guesses and can be impulsive. Because of his impulsive nature, Sonic can be reckless and quick to act before thinking, throwing himself into trouble without a second thought and regardless of other's warnings. Nevertheless, he is honest and always keeps his promises.

Sonic's personality is a juxtaposition of kindness and ferocity. He is extremely benevolent, driven by his own strong sense of justice and fair play, and firmly stands for freedom, but he is never the one to rest in the face of injustice or oppression. He hates all forms of evil, exploding with anger when witnessing it, and will do all he can to snuff it out, throwing his life on the line without hesitation. However, he usually sees his heroics as an opportunity to have fun, making him a thrill-seeker. In times of crisis though, he is aggressive and focuses intensely on the task at hand as if his personality has undergone an astonishing change. At the same time, Sonic has a big and gentle heart and is fully committed to help out and protect those in all kinds of trouble at any time, even if his actions will have ill consequences.

Sonic has a lot of self-confidence making him sassy, quick-witted, cocky, and at times overconfident. Sonic’s signature positive attitude is where his giant internal ego comes from; he thinks he and his friends will always find a way out of any situation, but that attitude sometimes leads him to underestimating his enemies and the task at hand. However, unlike his nemesis Dr. Eggman this ego is not to be confused with pride, as Sonic does not see himself as more important than others. No matter the threat or how dangerous, Sonic always remains cool under pressure. Also, Sonic is incredibly strong of character and will: no matter the situation, he never doubts himself and will never give up no matter what. It is only in the moments of greatest loss that his macho and carefree appearance falls away.

Sonic is extremely loyal to his friends and will risk his life for them without any due consideration. While he can leave them hanging or even endanger them due to his fast-paced nature, and at times acts rude, Sonic never has any intention of making his friends unhappy and values them above all else. Equally, Sonic is always willing to accept help from his friends if offered, and will show great trust in them, though he is not above making mistrusting assumptions of them.

Regardless of the countless foes he has faced, Sonic rarely considers them true enemies, and instead tends to admire them for how powerful some of them are and how much fun they have given to him. Likewise, Sonic is shown to have a remarkable capacity to forgive, forgiving Silver and working with him after he had tried to kill him twice.

Despite his outward demeanor, Sonic has shown to be much more insightful than he usually lets on, capable of seeing things others would have overlooked and can as well give valuable and comforting advice that drastically changes the outlook of others, such as Elise, Merlina and Blaze. This insight, combined with a charismatic personality, allows Sonic to get along with virtually anyone he meets even if at one point they were his enemies.

Sonic has a fondness of the beauty of nature and he stands as a protector of it. He appreciates scenic views inSonic Colors and showed anger and rage when he found out that Eggman was polluting Planet Wisp's beautiful environment. In Sonic the Hedgehog (2006), Sonic is also shown to have a fondness for locations that are filled with flowers, trees and other kinds of plants. Sonic has been shown to enjoy music, but seems to have an special interest in rock music.[41] Furthermore, it is displayed in Sonic Rush that Sonic also enjoys break dancing which is reflected in his Trick Actions. His battle moves in Sonic Battle are also based on break dancing, as mentioned in the attack descriptions. He also breakdances in numerous games usually when he is victorious.

Powers and abilities


Sonic's greatest strength is his superhuman speed, an innate talent that members of the hedgehog species possess,[42] though Sonic's has consistently proven to be in a class of its own. He has the ability to instantly accelerate to and run at speeds far greater than that of Mach 1,[43][44] which is at the blistering speed of about 760 mph, and he is both renowned the world over as "the fastest thing alive" and even the fastest being in the universe.[45] Additionally, he is able to run backwards at full speed just as well as forwards.[46] Due to such speed, he can scale right up vertical surfaces and ceilings, run over water, plow straight through foes, and even cause the ground to explode in his wake.

It is unknown how much faster Sonic can run beyond Mach 1. In Sonic Battle, it is stated that he can move several times the speed of sound and when facing Ultimate Emerl he went at least ten rounds with him in less than thirty seconds. It has often been stated that Sonic can move at supersonic speed[36] which ranges from 915-3,840 mph and he has been called the "the world's fastest, hypersonic hedgehog"[30] which ranges from 3,840-7,680 mph. Sonic is even stated to move faster than the speed of light;[47] E-123 Omega calculated that Sonic's speed can potentially reach light speed, and Sonic has implied that he can run faster than light.[48]Utilizing moves like the Light Speed Attack and Light Speed Dash, Sonic can achieve light speed movements as well.[49][50] Sonic has demonstrated complete mastery of his speed at any level. Not only can he run at maximum tilt in straight lines, but also in full tight circles and through sharp turns with full control over his momentum, and without recklessly crashing into unintended targets. However, he has trouble keeping his balance when coming to a sudden halt at full speed. As far as stamina goes, Sonic's is seemingly limitless as he is never winded from running. Additionally, Sonic can apply his speed for his other abilities: he canheal himself by vibrating his body, launch shockwaves by spinning at high speeds, leap in midair, kick out stunning energy waves and create barriers of super speed for a split second. Sonic can also set strong winds in motions with high-speed movements to attack opponents, similar to aerokinesis.

Physical abilities

Sonic has shown astounding feats of kineticism, precision and has reaction time to match his speed. He possesses incredible and flawless acrobatic skills and agility, alongside supernatural reflexes, making him able to avoid lasers and any incoming obstacles with precise and delicate movements, alongside with double jumps and wall jumps. When launched into the air, he can also perform several airborne tricks before landing. As demonstrated in his first meeting with Silver, Sonic can even sense attacks beyond his field of vision due to his sharp reflexes. He also has incredible jumping skills, allowing him to jump up to several hundred meters, even when carrying extra weight.

Sonic has demonstrated a degree of superhuman strength, though he has often been noted to lack overall raw power by comparison to others. He can push things several times bigger and heavier than himself, run without extra weight slowing down, and his various Spin Attacks are strong enough to cut through metal, gigantic boulders, burrow through the ground, and affect creatures countless times his size. However, it is debatable whether the latters power comes from his super speed, his super strength, or a combination of both. Most of Sonic's strength particularly lies in his legs; with a single kick, he can topple the colossal Egg Golem and knock back several Egg Gunner mechs at once. This does not mean that Sonic's arms are not strong either; in Sonic the Hedgehog CD where Sonic exhibited enough strength to tear robots apart by hands and in Sonic and the Black Knight he could smash through a collapsed wall.

Other abilities

Sonic has several times demonstrated extreme resilience to damage. He can survive getting caught in the crossfire from all angles by Eggman's robots (which only knocked him out cold briefly), withstand the force of a massive explosion and a Hyper-go-on-based black hole unscathed, being pummeled with swords, and can smash through several robots with his fist without any discomfort. It is also worth noting that, for nearly all the battles Sonic has endured, he has never been crippled or displayed any serious injuries. Additionally, Sonic has several times been able to survive impacts from free-falls at extreme heights, bordering at the edge of space, only to shake it off when landing, and even withstand atmospheric entry unharmed.

Sonic possesses an indomitable force of will; in situations where most others would give up and resign themselves to defeat or imprisonment, and where he is severely outnumbered and out gunned, he never loses faith in himself and never surrenders. This trait enables him to keep on fighting even when utterly exhausted or after taking an abnormal amount of physical punishment, and even withstand mind-controlling powers, like the corruptive influence of Dark Gaia as a Werehog and the Overmind's psychic powers, though in the latter's case he did have some protection. Even when possessed by the Ifrit, Sonic was arguably able to at least regain control for a few moments.

Sonic has also demonstrated the ability to harness the power of the Chaos Emerald for his own use. With a Chaos Emerald, Sonic can perform Chaos Powers, such as Chaos Control which lets him warp time and space, and occasionally gain a boost in power.

It is safe to say that Sonic is far stronger, faster and more skillful than he lets on, but his cocky, overconfidence and reluctance to use his more potent skills usually keeps him from fighting at full strength at all times though. Only in truly bleak situations does he reveal his true power - his victory over Ultimate Emerl (who had all the abilities of all his friends, 4,000 years worth of combat knowledge and all seven Chaos Emeralds) and the god-like Perfect Chaos in his base form are prime examples of this. In spite of his blocks though, Sonic ranks amongst some of the most powerful characters in the series.

Combat skills

Despite not having received any known training in martial arts, the many years of battles Sonic has been through has made him a powerful and skilled fighter, and a profound user of hand-to-hand combat, being able to go up against and beat others with far more experience. It has also been noted by people, such as Blaze andShadow, that Sonic's combat skills are always improving; in the different versions of Sonic Generations, Sonic was able to beat the Egg Emperor and Perfect Chaos on his own where he previously required additional support and power.

Fighting style

In battle, Sonic mainly tend to use his legs and fast footwork as his greatest strength lies mainly in his legs, though he will also sometimes use his arms too. His fighting style is primarily based on breakdancing, presumably with some elements of Capoeira added to it, which utilizes Sonic's legs to their fullest, allowing him wide-ranged and swift kicks. In Super Smash Bros. for Nintendo 3DS and Wii U, Sonic is also seen using flying forward kicks, split kicks, and scissor kicks in battle. Sonic's punches are straightforward, though sometimes consist of swinging his arm around for a short time and then release a charged punch.

What Sonic lacks in strength in a fight, he makes up for in speed by delivering faster strikes, either by landing several hits in a split second or striking foes with increased force. For stronger attacks, he tends to performSpin Attacks, Spin Dashes and Homing Attacks.

Even though he does not prefer to use weapons in combat (mainly dissing firearms as said in Shadow the Hedgehog), Sonic greatly excel in swordsmanship as seen in Sonic and the Black Knight. Even as a rookie, Sonic could a dragon with swordplay, and after receiving formal training, Sonic could match and defeating several members of the Knights of the Round Table. By applying his speed to his swordplay, Sonic can make quick and swift slashes and as well become a buzzsaw with his sword by spinning. He also has basic knowledge of how to use a Piko Piko Hammer in Sonic Advance 3 and landmines in Sonic Battle.

Techniques and moves

Many of Sonic's fighting moves are variations on the tendency for hedgehogs to roll into tight balls for protection. His primary offensive maneuver is the basic Spin Attack where he curls into a spiky ball when in motion that can damage, destroy, mow down, or burrow through many obstacles and foes. Through the series, he has expanded on this basic attack, which includes the Spin Dash where Sonic shoots himself forward as an acceleration roll at full speed while mowing down enemies and obstacles, the Spin Jump where he curls into a ball in midair to attack opponent by landing on them, and the Homing Attack where Sonic dashes in midair toward a target. He has developed the latter further with the Focused Homing Attack which can hit more targets and with greater force. He also several leg-based attacks, like the Slide, Foot Sweep and Flying Kick.

One of Sonic's less used signature moves is the Super Peel Out, or Figure 8 Dash, where he stays pivoted in one place and his legs move fast enough to create the illusion of an infinity symbol (more correctly a Möbius strip) beneath him. He holds this and then blasts forward, allowing Sonic to push himself out at extremely fast speeds. Another rare technique is the Blue Tornado where Sonic jumps into the air and creates a whirlwind by circling a particular spot at high speeds which can throw his opponents into the air or blow away armor and weapons. Sonic Wind is when Sonic creates a cyclone of blue swirling winds and fires it at the opponent. Sonic is also able to use the Light Speed Dash and Light Speed Attack which allows him to achieve light speed movements for either exploration or combat.

One of Sonic's newest signature moves is the Sonic Boost, a technique which increases his speed further, where he envelopes himself in blue aura and turn himself into a projectile, allowing him to destroy any enemy caught in his path. He does not even need to have contact with the ground in order to execute the move and can use it to temporarily fly immense distances through midair.

Miscellaneous skills

It is assumed that Sonic can control the strength or hardness of his quills. They appear to be extremely hard like buzzsaw blades when he is in spinball form, capable of shredding through several layers of reinforced steel to just about anything with enough speed. When he is not in spinball form, they appear soft and flimsy like rubber. In Sonic Heroes, his quills (and body) are durable enough to slice through battleships without even moving at the speed of sound. In Super Smash Bros. Brawl, he can temporarily increase the durability of his quills to hit opponents in his Up Throw. In this move, he throws up an enemy, goes into a push-up type pose, and flares up and hardens his quills for the enemy to land on. In Sonic and the Secret Rings, during Dinosaur Jungle, Sonic mentions that his quills can also sense danger, before being attacked by a dinosaur.

Sonic has proven himself as a world-class Extreme Gear rider. On an Extreme Gear, he can move even faster than he can run[51] and go head-to-head with the best Extreme Gear riders the world has to offer, namely Jet the Hawk. Sonic seemingly has a natural talent for Extreme Gear riding, as he quickly grasped the controls on his first try and can perform several advanced techniques despite being self-taught. After the events of Sonic Free Riders, Sonic can be considered the best Extreme Gear rider in the world, as he was able to beat Metal Sonic in a race, who at that point possessed all the data and skills of the world's best Extreme Gear riders.

In Sonic Generations, Sonic is shown to transfer his speed throughout various parts of his body (which may explain why he is able to boost in midair from a stationary position, negating certain physics), and on the second act of Planet Wisp, Sonic can even transfer to objects, as he can force a coal-carrying platform to speed up its movement by using his pure speed to make it go faster, and overtake other platforms (as well as crash into and break them).


Super Sonic

By using all seven Chaos Emeralds, Sonic can enter a Super State, transforming him into Super Sonic. Easily his most frequent transformation, Super Sonic is Sonic's ultimate form. In this state, all of Sonic's abilities far surpasses his normal ones and he is as well able to fly and is nearly invulnerable.[52] However, this transformation consumes a lot of energy and requires Rings to be maintained.

Hyper Sonic

In Sonic the Hedgehog 3 & Knuckles, by using the power of the seven Super Emeralds, Sonic can achieve an extended and more powerful form of Super Sonic, called Hyper Sonic. This form basically shares the same abilities and traits as Super Sonic, except they are all more powerful and upgraded.

Darkspine Sonic

In Sonic and the Secret Rings, by harnessing the World Rings of rage, hatred, and sadness, Sonic can become Darkspine Sonic, a form powered by his emotions at Shahra's death. In this state, Sonic can fly, has greater strength, unlimited use of the Soul Gauge powers and pyrokinetic abilities. Because of the intense emotions sealed inside the World Rings that Sonic uses to transform, however, he becomes slightly darker and more violent.

Excalibur Sonic

In Sonic and the Black Knight Sonic is able to transform into Excalibur Sonicby using the power of the four sacred swords. This form grants him a strong golden armor with a red cape, the ability to fly, greater strength and the power to wield the legendary sacred sword, Excalibur.

Sonic the Werehog

In Sonic Unleashed, Sonic unwillingly gained the power to turn into a werewolf-like version of himself named Sonic the Werehog at night time by absorbing the energies from Dark Gaia. In this state, he loses his trademark speed, but still retains his lightning reflexes and agility. He also gains super strength, the ability to stretch his arms, and limited energy manipulation. While Sonic's strong will prevents him from going bonkers like other people affected by Dark Gaia, he does gain some minor feral behavior. He permanently lost this transformation after his battle with Dark Gaia.

Color Power transformations

By harness different variants of Hyper-go-on from Wisps, Sonic can use certain Color Powers to transform into a specific form, such as a drill, a laser or even a fireball, with the Color Power depending on the type of Wisp. The Color Power forms used by Sonic so far include the Cyan Laser,Yellow Drill, Blue Cube, Green Hover, Pink Spikes, Purple Frenzy, Violet Void, Orange Rocket, Red Burst, Indigo Asteroid, Magenta Rhythm,Crimson Eagle, Ivory Lightning, Gray Quake and Black Bomb. However, these transformations require a steady supply of Hyper-go-on to be maintained.


Noted to not be the strongest swimmer, Sonic is incapable of swimming properly and sinks like a stone in water. This may be due to aquaphobia (Sonic thinks that if he falls into water, he will be trapped with no one to get him out), though he does not demonstrate that fear very often. In some situations, he can bypass his weakness to water by running or sliding across its surface, leap out of the water with successive jumps, and survive extended periods of time underwater with air bubbles.

It has been stated that if Sonic does not sleep for eight hours during the night, it will spoil his running. In addition, he has trouble keeping his balance when coming to a sudden halt when running at high speed.

Sonic always thinks on the positive side and believes no matter what, he will always find the light. Because of this mindset that he and his friends can to anything, Sonic has a giant internal ego, he often banter and play around with his enemies. This often makes him underestimate his opponents and leave his guard down, as seen during his encounter with Infinite in Mystic Jungle during the War to Take Back the Planet and when he got trapped by Eggman onboard the Chaos Energy Cannon at the start of Sonic Unleashed.

Sonic never second guesses and will always do what’s right. While this is selfless and a huge virtue it can cause Sonic to be impulsiveness and recklessness which often causes trouble, such as during the Lost Hex incident where he got rid of Eggman's Cacophonic Conch, which Eggman used to keep the Deadly Sic in line, before listening to Tails' warnings about the conch.

Sonic believe everyone deserves freedom so will become very impatient when constrained when normally carefree and easygoing. Also because of this belief of freedom Sonic speaks to everyone in a informal and friendly manner even authority which often makes G.U.N. angry with him for not treating them highly.

Sonic doesn’t think of anyone as enemies and thinks of them as competition or a thing he has to overcome. Because of this Sonic forgives people quite easily such as Knuckles, Silver, Merlina and even Shadow. But in some media like IDW comics this quality of Sonic is put to the test as sometimes his compassion can cause the worse such as when Metal Sonic reverted Mr. Tinkers memory’s to Eggman.


During his adventures, Sonic has encountered many people and throughout it all, he has received many friends and foes alike. Sonic is well-known with his brotherly relationship with Tails, his friendly rivalry with Knuckles and his fierce arch-rivalry with Shadow. Sonic's arch-enemy is Dr. Eggman, but Sonic has come across even greater enemies throughout his adventures.

Dr. Eggman

Dr. Eggman is Sonic's eternal arch-enemy and nemesis, whom he has known longer than anyone else. Along with Tails, Eggman is one of the figures who has often shaped Sonic's destiny.[54]Because of Sonic's hatred of anything unjust, he holds a great mutual hatred for the doctor and his evil plans to take over the world, and he has spent years rescuing the victims of Eggman's conniving schemes.[33]Whenever Eggman is cooking up a plan to conquer the world, Sonic always shows up and thwarts him. Because they always fight each other to win, Eggman has become a long time rival of Sonic's as well as an enemy.[55] Also, whenever Sonic's unfriendly emotion explodes over injustice, he always makes Eggman the receiving end of this aggression.[34]Despite his dislike of Eggman, Sonic has never really taken account of his adversary and does not consider him his enemy in the true sense of the word.[18][40] Whenever dealing with Eggman, Sonic remains fully confident that he can spoil his plans and never really takes them seriously. In fact, Sonic finds entertainment in spoiling Eggman's plans, which he sees as a way of making his life an adventure, and he is so used to beating him that he considers it an everyday job.[40][56] Usually, Sonic is rather frank or taunting towards Eggman and will almost always seize the opportunity to tease him with jokes and sarcasm. Sometimes, Sonic even finds Eggman more bothersome and annoying than threatening: when he discovered Eggman was behind the Time Eater in Sonic Generations, Sonic just face-palmed and shrugged disapproving. Nevertheless, he remains vigilant about Eggman and his actions, like when he alone refused to believe that Eggman had turned over a new leaf in Sonic Colors. In the cases Sonic does deem Eggman a legitimate threat though, he becomes very serious about the doctor and targets him with fierce opposition.

When presented with a more terrible threat that endangers both of them and their goals, Sonic is willing to put aside his differences with Eggman and join forces with him to stop it. Even in such cases though, Sonic remains reluctant about it, feeling that teaming up with Eggman is like the end of the world and a dirty affair,[57] and will in some cases suspect the doctor has an ulterior motive (which is often proven true). Because of Eggman's complicated tendency to instantly switch between morals, Sonic has a hard time figuring him out.

While Sonic has been know to make fun of Eggman by using his alias instead of his real name[58] (which was possibly given by Sonic), he actually uses this name affectionately, rather than trying to make fun of him.[59]

In spite of Eggman's deeds, Sonic is content with just stopping the doctor and is never out to put him out of commission for good on purpose. Because of Eggman's tendency to survive their encounters and refusal to give up however, the doctor always returns with a new scheme, prompting Sonic to stop him again. As such, Sonic remains forever locked in a conflict with Eggman where it is nearly impossible for both individuals to defeat the other once and for all, making their battle a never ending one.

Miles "Tails" Prower

Miles "Tails" Prower is Sonic's best friend and sidekick, as well as his most faithful and loyal friend.[60] Besides Eggman, Tails is one of the figures in Sonic's life who has often shaped his destiny.[54] Sonic first met Tails on West Side Island where he noticed Tails was following him, but was not interested and ignored him. However, when he noticed that the fox cub kept following him and could keep up with his speed, Sonic grew impressed with his tenacity and ability to keep up, and decided to let him tag along.[19]When Dr. Robotnik soon after attacked West Side Island, Sonic joined up with Tails when the fox followed him into the conflict.[19] Over their adventure, Tails proved himself a great assistance to Sonic and after defeating Robotnik, the two had built the foundation for the unbreakable friendship that would define their future. Sonic eventually took Tails under his wing[38] as his sidekick and began taking him with him on his adventures and training with him, eventually becoming his protégé.[61] Additionally, Sonic would come to Tails' aid by stopping the bullies who would tease him for his twin-tails, which only improved Tails' admiration of him.[62]Since becoming friends, Sonic and Tails have been inseparable, their friendship having grown to the point where they have a brotherly relationship. In Sonic Advance 3, they are even noted to have an "Unbreakable Bond," and when Tails was mind-controlled into fighting Sonic in Sonic Colors, Sonic never laid a finger on him, refusing to hurt his friend. Sonic himself sees Tails as a cute "adopted" kid brother and looks over him accordingly.[38][62][63] Nevertheless, Sonic respects and trust Tails immensely and treats him as his equal partner in their adventures. Whenever on an adventure, Sonic always asks Tails to come along and will always accept his help. At times, however, Sonic will ignore Tails when he gives advice or information, often when it's most useful, though he is not too big to admit he should had listened to him.

Sonic cares very much about Tails' well-being, even threatening those endangering him, and will always make Tails' safety his top priority above all else when he needs it, even if it means abandoning a fight, forcing Tails to leave for his safety, or make saving the world his secondary objective. Whenever Tails doubts himself, Sonic is always there to give him moral support. Throughout their adventures, Tails has continuously proven himself as Sonic's most reliable ally, always providing him with invaluable help, knowledge, and machines. In turn, Sonic is impressed with and appreciates Tails' work and considers his technical skills better than any other's, though this faith makes him leave all the tech work to him.[64]

In Sonic Lost World, Sonic unintentionally strained his friendship with Tails when he planned for Eggman to do the necessary tech work to save the world, which made Tails mad at Sonic for trusting Eggman more. It was further strained when Tails endangered himself when using a battle bot to help and Sonic scolded him. At the end though, Sonic apologized for doubting Tails and Tails forgave him, mending their brotherly bond.

Amy Rose

Amy Rose is one of Sonic's oldest and most loyal friends,[65] and his self-appointed girlfriend.[66] Since before and after meeting Sonic, Amy has looked up to him as her hero and been madly in love with him, and her greatest wish is to marry him. Sonic first met Amy during his adventures on Little Planet where he saved her from Metal Sonic and Dr. Robotnik's captivity which made them fast friends.[38] Right from the start though, Sonic has not liked her like a girlfriend or reciprocate her advances,[65][67] though it has done nothing to deter Amy.

Since their first meeting, Amy has chased Sonic down wherever he goes, with Sonic seemingly unable to escape her,[68] and has tried to win his heart by any means. Sonic, however, is rather annoyed by her affection and even disturbed by her over-the-top displays, which makes him treat Amy as little more than an annoyance and deem her weird.[69][70] As such, Sonic considers Amy a near constant pain in his life.[71] Whenever Amy tries to show him affection, Sonic gets rather uncomfortable, exasperated or embarrassed and will try to avoid her when she goes overboard, usually by running away or by more rude means. He also refuses the idea of marrying Amy, preferring to be locked up (which is no small statement considering Sonic's loathing of being constrained) as seen in Sonic Adventure 2. Additionally, Sonic is scared of Amy's anger which makes him nervous or run away in fear when he thinks he will provoke her, and he often finds himself overwhelmed by her powerful personality.[31] Over the course of the series, Sonic running away from Amy has become a running gag.

Regardless of how much dismay Amy has put Sonic through, she is considered one of his close friends.[45] It is stated that in his heart he may not dislike her as much as it seems,[34] and that deep down he might actually have some feelings for her.[72] In Sonic Unleashed, Sonic was stumped that Amy did not recognize him as the Werehog, and when he shortly after saved her from some of Dark Gaia's Minions, he initially chose to run away than face her with his condition. Additionally in Sonic Lost World, Sonic was crestfallen when he thought Amy and the others had died from the Extractor.

Overall, Sonic cares about as Amy a good friend and worthy comrade whom he can rely on and he appreciates her efforts to help him when she is not flirting with him. Also, whenever Amy is in trouble, Sonic will always be there to help her out should the need arise, though he tends to overlook her when she is caught in the middle of his showdowns with the villains.

Metal Sonic

Metal Sonic is Sonic's robotic alter ego, created by Dr. Eggman for the sole purpose of destroying him.[73] He is one of Sonic's earliest foes[74] and his first true rival, being able to copy both his speed and power,[73] and they have a violent rivalry/enemy relationship. Sonic first encountered Metal Sonic on Little Planet where the robot kidnapped Amy Rose, forcing Sonic to defeat him to save Amy, inadvertently turning Metal Sonic from one viewing him as an enemy into a bitter and deadly rival.[75] On the other hand, Sonic has never considered Metal Sonic his enemy in the true sense of the word.[40]

Since meeting each other, Sonic and Metal Sonic have almost always fought whenever they meet, never once having an instance where their objectives align. In Sonic's opinion, Metal Sonic is the worst creation Dr. Eggman has ever made, due to how it always causes trouble for him, and he views him as a very serious threat.[76] Regardless, Sonic always remains confident that he can beat Metal Sonic and considers him a "lame robot copy" which can never match up to the original that is him,[77] though it does not keep him from enjoying testing his skills against him.[40]

Over time, Sonic and Metal Sonic have had countless fights. While Metal Sonic is one of Sonic's few rivals who have come the closest to defeating him,[73] Sonic has always beaten him in the end. However, these defeats only served to increase Metal Sonic's hatred for Sonic and endowed him with an obsession to surpass and defeat him, promoting him to repeatedly challenge him in vain. In Sonic Heroes, Metal Sonic's hatred and obsession for Sonic pushed him over the brink, making him usurp control of the Eggman Empire to build a robot kingdom with the goal of killing Sonic. He even adopted the warped belief that Sonic was his copy and that he was the real Sonic. In the end, Sonic still defeated him, and while Metal Sonic refused to give up after that, Sonic promised his robot double that he would await their future rematches.

Knuckles the Echidna

Knuckles the Echidna is one of Sonic's greatest rivals and best friends.[37][68] They have known each other for a long time, but their relationship is somewhat complicated. Sonic first met Knuckles in Sonic the Hedgehog 3where they started off as enemies, with Knuckles trying to keep him from stopping the Death Egg's re-launch. However, when they discovered that Dr. Robotnik had tricked Knuckles, the two of them joined forces to keep Robotnik and his robots from stealing the Master Emerald, and they departed on good terms.

Sonic and Knuckles are much like oil and water. While Sonic exemplifies the wind, laid-back, cool and free, Knuckles is the mountain, stern, serious and unmovable,[78] which cause them to argue a lot. Because of their differences and morals, they do not understand each other and they do not always see eye to eye.[79] They share a competitive rivalry and they often end up fighting when clashing, though their rivalry has become more friendly over time. With Sonic's speed equaling Knuckles' strength in every way, their fights are always climactic, though at times unsettled, which only provokes them to clash further.

Knuckles sees himself as Sonic's rival, though it is implied it is because he envies Sonic's free lifestyle and self-reliant nature.[63] Sonic meanwhile, always welcomes a challenge from Knuckles and enjoys teasing him for fun because of his serious nature, and will even try getting him angry so he can fight him. Whenever Sonic discovers Eggman has tricked Knuckles, he always chides him by calling him "Knuckle-head," though he always makes peace with him at the end of the day.

Despite their differences, Knuckles is Sonic's best friend next to Tails. The two of them are connected by a hot-blooded friendship[80] and according to Tails, they are "funny" together. While Sonic does not hold back on Knuckles' shortcomings, they deeply acknowledge each other[80] and Sonic knows he can count on him to do what is needed to succeed.[79] Over time, their relationship has improved and they argue less, though Sonic is somewhat reluctant to admit when Knuckles is right and he was wrong.[81] While Knuckles at times rebuts his help and claims he could do better, Sonic just rolls with it and is merely glad to help him. The two are also great and loyal teammates, having been called "Fighting Buddies" in Sonic Advance 3, and when they work together they form an unstoppable team. For better or worse, Sonic will also be there to give Knuckles needed, if not harsh, consoling whenever he is in doubt. Additionally, in Sonic Lost World, Sonic was crestfallen when he thought Knuckles and the others had died from the Extractor.

Shadow the Hedgehog

Shadow the Hedgehog is Sonic's arch-rival. They look almost identical (to the extent that many got them confused in Sonic Adventure 2), and they can match each other in speed, agility and abilities,[82][83] including Chaos Control. The two of them first met each other as enemies, with Sonic holding a grudge at Shadow for getting him into trouble with GUN, but they put aside their differences to team up and save the world from Gerald Robotnik's doomsday plans. Since then, they have been both lethal enemies and comrades.[84]

Shadow is the antithesis to all that Sonic stands for,[54] and ever since they first met they have fought, argued, and even sometimes had outright death matches, though Sonic is never out to take Shadow's life and does not consider him an enemy in the true sense of the word.[40]Their moral differences are as far apart as black and white, always causing the two of them to clash. Sonic has a joyful, free-spirited attitude that looks for fun adventures, while Shadow is a brooding loner with a merciless and excessively violent edge.[85] Sonic has few limitations on his goals and will do anything to help save the world, but Shadow will stop at nothing to get what he wants without any concern of who or what it affects.[85]Nevertheless, they do not care of each other's views and they always see their conflicting differences as yet another reason to fight each other.

Both Sonic and Shadow initially shared a bitter arch-rivalry. When they first met, Sonic accused Shadow of copying him, with Shadow maintaining a mutual belief regarding Sonic. This feeling is still present in both of them because each believes he is better than the other. Regardless, their rivalry has developed over time and is now more friendly.[86]

Out of all his rivals, Shadow is the one whom Sonic struggles most with. As shown in all the clashes between them, they are nearly equally strong or as strong as the other, with both sides neither lacking in any category that separates them from skill in their respective prowess. It is shown that while Sonic is becoming faster and more honed than Shadow, Shadow is becoming stronger and more destructive than Sonic, which has only increased the intensity of their arch-rivalry. They have an unshakable need to showcase their growth and improvement for every encounter they have, and anything considered competitive is suitable for their rivalry, though Sonic usually remains more casual about it than Shadow and enjoys testing his skills against him.[40]

Despite their differences, Sonic and Shadow share a mutual respect between them,[87] though this is rarely apparent because they always argue and fight. During their adventures, Sonic has acknowledged Shadow's power and capabilities,[88] even admitting that Shadow is only one who would have a chance against him in a race,[44] and after Shadow sacrificed himself to save the world in Sonic Adventure 2, he recognized him as a brave and heroic hedgehog.[89] Sonic also appears to hold faith in Shadow's sense of right and wrong to a certain extent, as seen in some of the scenarios of Shadow the Hedgehog where he would show disbelief and confusion about Shadow siding with the Black Arms,[90] and even admitted in one scenario that he did not believe Shadow had it in him for his selfish acts.[91] Regardless of their objectives, they are willing to put their differences aside for the greater good if they must, and together they are an unbeatable team. Overall, there is always extreme tension between Sonic and Shadow, but they have matured over time, with Sonic having become more acceptant of Shadow's violent tendencies.

Blaze the Cat

Blaze the Cat is one of Sonic's close friends and most valuable allies.[92] He first met Blaze in Sonic Rush where he initially suspected she was involved with Dr. Eggman Nega's current world-conquering scheme. When he found Blaze, Sonic learned she was not an enemy but was actually working on saving the world, though she wanted to bear that responsibility alone. Sonic insisted they should help each other, but Blaze refused. Regardless, Sonic followed Blaze into a showdown with Eggman and Eggman Nega where he would not let her fight alone. However, Blaze still refused his help and fought him to make him leave.

As they fought, Sonic tried to stop Blaze, but she berated him with the full fury of her emotions. After their battle, Sonic understood she had a rough past and he told her not to handle too much alone and be true to herself. This advice made Blaze realize that accepting help would benefit her, and they properly introduced themselves and became friends. Later, when Blaze lost faith in herself when the Sol Emeralds lost their power, Sonic showed up and cheered her up which let her become Burning Blaze, and they defeated Eggman and Eggman Nega together. After the battle, they said goodbye, where Blaze thanked Sonic and they promised to meet again.

Following their first adventure, Sonic and Blaze have steadily become better friends and trusty allies. The two have a custom that when they have to depart after an adventure, they shake hands, signifying their growing friendship and respect following their encounter and the promise that they will meet once more.

Sonic and Blaze are alike in many ways, having similar skills and duties, yet very different backstories and contrasting personalities: Sonic being inwardly free and adventurous, yet outwardly level-headed and cool, whereas Blaze is outwardly stoic and blunt, yet inwardly highly emotional. However, their differences does little to hurt their relationship and is later shown to mix very well in Sonic Rush Adventure as their friendship and mutual understanding grows. They are also shown to be great partners in combat and they work well together, almost as in sync.

Sonic and Blaze share a great deal of mutual respect and trust. Like Blaze respects Sonic and his skills, Sonic has acknowledged Blaze's skills after she matched him in direct combat and he willingly entrusted her to bringCream back safely shortly after befriending her while she trusted him to face Eggman Nega. Also, whenever Blaze's emotions get the better of her, Sonic shows concern for her and calms her down, like when he told her to remember her duty to her people when she was taking a risk to fight for the Jeweled Scepter. Additionally, Sonic is responsible for many changes in Blaze's outlook on life. Their time together enabled Blaze to discover the meaning of friendship which ultimately let her use the Sol Emeralds,[93] and his advices made Blaze accept her pyrokinetic powers as a gift rather than a curse.

Silver the Hedgehog

Sonic and Silver first met during the events of Sonic the Hedgehog (2006). The two were enemies at first because Silver had traveled though time and was intending to kill Sonic believing that he was responsible for destroying his world by releasing Iblis onto the world and was bent on saving the future. But Silver befriended Sonic when he discovered that Sonic was not the Iblis trigger and that Mephiles the Dark had lied to him. The two worked together to savePrincess Elise and when Sonic was killed by Mephiles, Silver realized that they could save Sonic with the power of the Chaos Emeralds. Afterwards Silver teamed up with Sonic and Shadow to defeat Solaris. But since the events of the game were erased from history, Sonic and Silver never met. They do not actually meet until Sonic Rivals where Silver has traveled to the past to bringEggman Nega back to the future, but Silver seems to be more competitive to Sonic as they raced each other see who would get to Eggman Nega first but later they teamed up with each other at the end to defeat Eggman Nega and also in Sonic Rivals 2 to defeat the Ifrit. It appears that Sonic and Silver do not remember each other from their past adventure since the events of Sonic the Hedgehog (2006) were erased.

Silver seems to have a bit of a disliking towards Sonic mostly because he thinks that he is cheeky and foolish, much the same how Shadow thinks of Sonic at times. Silver's attitude tends to annoy Sonic at times as well as seen in Sonic Rivals when he says, "Yo Silver, you've got an attitude". But they will work together and lay aside their differences whenever the time is right. An example is in Sonic Colors after Silver challenges Sonic to a mission, he asks if he needs any help. In Sonic Generations, Silver is the only rival who wants a friendly fight. He also appeared at the Center of Time after Sonic was knocked out by the Time Eater, Silver says to Sonic: "I know you can do this Sonic!".

Jet the Hawk

Sonic and Jet have been rivals since they met, and their relationship is based on their competitive nature and their distinct respect for one another. When meeting with each other for the first time, Sonic was beaten by Jet when facing him on an Extreme Gear. However, Sonic was left rather impressed by Jet's skills and instantly recognized him as a new rival.

During Eggman's first EX World Grand Prix, Sonic was not exactly fond of Jet as he constantly taunted and insulted his attempts at mastering Extreme Gear, often getting very angry at him. While thinking Jet was rather full of himself, Sonic still recognized his skills as an Extreme Gear rider and held a determined, albeit one-sided at the time, rivalry with him. Whenever he was around him, Sonic would keep a professional, yet competitive, attitude around Jet. Eventually, Sonic settled his own dispute with Jet when he beat him in a race. At the end of Sonic Riders, Sonic had a more friendly relationship with Jet, as each of them had respect for one another, and promised each other to compete once again, though they both still remained firm rivals.

Since defeating Jet, Sonic has hold a more relaxed and friendly attitude towards Jet, taking his insults and rash determination to beat in a race him in stride. Nevertheless, Sonic's rivalry with Jet remains as strong as ever, and he will gladly, if given the right opportunity, face him in a race for excitement and fun. However, even when determined to beat Jet, Sonic does not wish to have any unfair advantages, and is willing to give Jet both the chance to prove himself and face him at his best. Despite how many times they face each other, Sonic always looks forward to his next rematch with Jet.

The Deadly Six

The Deadly Six, a gang of villainous Zeti initially controlled by Dr. Eggman, are some of the worst enemies Sonic has ever faced. Unlike his past foes whom he has never viewed as actual enemies, the Deadly Six are the only ones Sonic has shown true hatred and contempt for and has held a personal grudge against.

Sonic first met the Deadly Six on the Lost Hex, where he treated them with confident mockery like any other foe. However, when Sonic recklessly got rid of the Cacophonic Conch used to control the Deadly Six, they rebelled and planned to destroy the world, making Sonic responsible for their uprising and the subsequent danger to the planet. As such, Sonic set out to stop them more seriousness. Sonic would soon after grow extremely hostile towards them when they captured Tails, an act of which made Sonic lose his cool for once. In his quest to save Tails from them, Sonic would respond to the Deadly Six with aggressiveness and spite which only intensified as Zavok taunted him with his plans to make Tails a robot and his friends' apparent deaths. In their final showdown, Sonic moaned of how tired he was of them and responded back at them with violence when he thought they turned Tails a robot. In the end though, Sonic defeated the Deadly Six and got Tails back, redeeming his actions his involvement with the Deadly Six had brought and proving himself the hero he is.

Animation and anime

Adventures of Sonic the Hedgehog

In Adventures of Sonic the Hedgehog, Sonic is a world-roaming Freedom Fighter with a lifestyle similar to a tramp, who fiercely defends the citizens ofMobius from the evil schemes of Dr. Ivo Robotnik and his lackeys Scratch andGrounder in several comical adventures.

One day, Sonic came across a young orphan named Miles Prower and was persuaded to adopt him as his younger brother, as the young fox had no one to live with. Naming him new brother "Tails", they two of them became as close as a real family. While Sonic has his trademark attitude, he also tries his best to stand out as a responsible role model for the innocent Tails.

Sonic the Hedgehog (TV series)

In the Sonic the Hedgehog television series, Sonic lived in Mobotropolis with Princess Sallyand the future Freedom Fighters during their childhood until Dr. Robotnik invaded the kingdom, enslaved the people with the Roboticization technology and took control of the planet.

Sonic and his friends managed to escape the tyrant by fleeing into the Great Forest where they built a village named Knothole to hide from Robotnik. There Sonic, Sally, and the others then formed the Freedom Fighters and began a ten year long battle with Dr. Robotnik to take back their planet, with Sonic being one of the main leaders and their primary agent. After many battles and guerilla tactics, Sonic and Sally defeated Robotnik when the doctor launched his Doomsday Project.

Sonic Underground

In Sonic Underground, Sonic was born as the heir to the throne of Mobius, along with his siblings, Manic and Sonia. Shortly after their birth however, their mother Queen Aleena was dethroned by Dr. Robotnik and they became wanted, but the Oracle of Delphius prophecized that Aleena and her children would one day defeat Robotnik together, but only if she left her children in the care of others until then.

Sonic himself was left in the care of a regular family. During his early childhood, however, his adopted family was captured and roboticized. He then joined his Uncle Chuck and the Freedom Fighters in the battle against Robotnik over the next many years. One day however, Sonic was approached by the Oracle who revealed to him his origin and family. Sonic soon after reunited with his siblings and together they formed the band Sonic Underground where they fought Robotnik while searching for their mother.

In this media, Sonic possess a medallion that transforms into an electric guitar/laser rifle.

Sonic the Hedgehog: The Movie

In Sonic the Hedgehog: The Movie, Sonic lives on Planet Freedom and is one of the defenders of the Land of the Sky, alongside Tails, who protects it from the evil Dr. Robotnik and his forces. He lives with Tails on their own private island.

One day, Sonic and Tails were called by Dr. Robotnik to battle an evil robot namedMetal Robotnik and save their planet from destruction. This was however a trick on Robotnik's behalf so the evil doctor could copy Sonic's data into his Hyper Metal Sonicrobot. After the doctor succeeded with his plan, Sonic worked together with his friends and allies to stop his metallic copy from destroying the world.

Sonic X

In the anime series Sonic X and its comic series published by Archie Comics, Sonic originally lived on a parallel version of earth in another dimension. During one of his battles with Dr. Eggman, a massive Chaos Control blast occurred and Sonic, his friends and Dr. Eggman were transported to Earth. Shortly after arriving, Sonic nearly drowned in a pool, but was saved by Christopher Thorndyke, who Sonic became friends and lived with. In time, Chris came to have a strong bond with Sonic as he lived a lonely life since his famous parents were always busy.

Sonic eventually settled down on this new world with his friends and became a famous hero among the human population as he and his friends protected the world from Dr. Eggman as the doctor continuously attempted to conquer earth. Eventually, Sonic and everyone from his world were forced to return home as their presence threatened to freeze time. Before Sonic could return home however, Chris, who did not want him to leave, ran off with him, but Sonic eventually made Chris come to terms with his feelings and Sonic returned home.

Six months after coming back home, Sonic teamed up with his friends and Chris, who had just arrived in Sonic's dimension, to fight the Metarex, an alien race of cyborgs that was a threat to the safety of the entire galaxy. With everyone's aid, Sonic managed to defeat the Metarex and their leader Dark Oak and saved the galaxy. Upon returning to his home planet, Sonic had his goodbye with Chris, who went home, and Sonic himself went back to his normal battles with Dr. Eggman.

Sonic Boom

In the Sonic Boom franchise, Sonic is the leader of Team Sonic, a group of heroes who protects Bygone Island and the earth at large from Dr. Eggman and his legion of robots. Though initially kind of a loner, the many trials Sonic faced during his battles against Lyric taught him the importance of teamwork, and he has since grown into a capable and admirable team-mate and leader.

Books and comics

Sonic's first comic appearance was in a promotional comic printed in Disney Adventures magazine, which established an origin for Sonic involving the transformation of kindly scientist Doctor Ovi Kintobor into the evil Dr. Ivo Robotnik. Numerous British publications, including "Sega handbook" Stay Sonic (1993), four novels published by Virgin Books (1993–1994) and the comic book Sonic the Comic(1993–2002) used this premise as their basis.

The American comics published by Archie Comics, Sonic the Hedgehog (1993—present), Sonic X (2005—2009) and Sonic Universe (2009–present) are based on the settings established by earlier animated TV series, the Sonic the Hedgehog cartoon and the Sonic X anime respectively.

In Japan, various Sonic manga have been published.

Sonic the Hedgehog (Shogakukan)

In the serialized manga series published by Shogakukan between 1992 and 1994, Sonic is the heroic alter ego of a young, timid hedgehog boy named Nikki. Nikki transforms into Sonic whenever he wishes he had the strength to overcome a dangerous or stressful situation, but nobody (even Nikki) is aware of this transformation.

Nikki's girlfriend Eimi also has a crush on Sonic, and Nikki's father Paulie, a pilot, claims that Sonic once saved his life long before Nikki was even born.

Archie Comics

In the Sonic the Hedgehog comic book series and its spin-offs published by Archie Comics, Sonic is a Freedom Fighter and the gratest and most famous hero on his world. Sonic was born during the Great War toJules and Bernadette Hedgehog and was originally named after his grandfathers (he later legally changed his named to "Sonic" with no offense to his forebears). While very young, he lost his parents to the first clandestine roboticizationexperiments. He was taken in by his uncle, Sir Charles Hedgehog, where he briefly played delivery boy for his uncle's chilidog stand while spending time inKnothole. Aside from his abnormal speed, Sonic was an average child.

Tragedy struck when Uncle Chuck was captured Dr. Ivo Robotnik and his forces following the doctor's takeover and roboticizied. Sonic and a few others were herded to Knothole by the Original Freedom Fighters who gave Sonic the inspiration that would make him a hero. From there, Sonic threw his full support behind the Knothole Freedom Fighters and fought to liberate the kingdom. Sonic playfully took on Dr. Robotnik's first few generations of badniks, growing in skill until, by his mid-teens, he was a true threat to Robotnik's forces and became a beacon of hope for the world.

As Sonic developed his incredible speed, his attitude became legendary. Irreverent, confident, impatient and energetic, Sonic fought constantly and eventually succeeded in overthrowing Dr. Robotnik, and continues the fight against his successor, Dr. Eggman. During his adventures, he has traveled the globe, and even traversed outer space, alternate dimensions, and time itself. He has been named the chosen hero of the multiverse, having throughout his endeavors faced down mad scientists, evil wizards, warmongering aliens and even gods. Following Operation: Clean Sweep though, Sonic met several loses that lead to the disbandment of the Freedom Fighters, making him assume leadership of Team Fighters to continue the fight. When the secondGenesis Wave was unleashed, Sonic teamed up with Mega Man to bring their universes back to normal, though the timeline of Sonic's universe was forever altered in the process.

Sonic the Comic

In Sonic the Comic, Sonic was once an ordinary brown (though still fast) hedgehog on the planet Mobius. He encountered a kindly scientist namedDoctor Ovi Kintobor, who performed experiments on his speed. An explosion resulted in his spines fusing together and turning blue. A later experiment, involving Kintobor's attempts to rid Mobius of evil, transformed the good doctor into Ivo Robotnik. After several unsuccessful attempts to take over the world (as depicted in the first two Sonic games), Robotnik finally managed to conquer the planet by sending Sonic six months into the future. On his return, Sonic took it upon himself to form a group of Freedom Fighters to depose Robotnik, which they finally managed to do in the series' landmark 100th issue.

As in other continuities, Sonic is aided in his adventures by his loyal sidekickTails, as well as Amy Rose and original characters Porker Lewis, Johnny Lightfoot, Tekno the Canary and others. He has a friendly, though still quite intense, rivalry with Knuckles the Echidna, who frequently accuses Sonic of bringing trouble onto his Floating Island.

Sonic can turn into Super Sonic in this continuity without exposure to the Chaos Emeralds (because of a dose of radiation he received when the Emeralds were first brought together), but in this form he is out-of-control, bordering on psychotic and he attacks friends and enemies alike. The two were separated for an extended run, but re-united in the series' final story arc.

Sonic the Hedgehog series video games

Sonic's first appearance in video games was in the racing game Rad Mobile. Sonic's first major appearance was in the platform game Sonic the Hedgehog for the Sega Mega Drive/Genesis, which also introduced his nemesis Dr. Robotnik. His two-tailed fox friend Tails joined him in the game's 1992 sequel, Sonic the Hedgehog 2. Sonic CD, released in 1993, introduced Sonic's self-appointed girlfriend Amy Rose and recurring robotic doppelgänger Metal Sonic as Sonic traveled through time to ensure a good future for the world. Sonic 3 and its direct sequel Sonic & Knuckles, both released in 1994, saw Sonic and Tails battle Robotnik again, with the additional threat of Knuckles, tricked by Robotnik into thinking Sonic was a threat to his home. Sonic 4 (2010) continues where the story of Sonic 3 left off, reducing Sonic to the only playable character and releasing in episodic installments.

Other two-dimensional platformers starring Sonic include Sonic Chaos (1993), Sonic Triple Trouble (1994), Sonic Blast (1996), Sonic the Hedgehog Pocket Adventure (1999), Sonic Advance (2001), Sonic Advance 2 (2002), Sonic Advance 3 (2004), Sonic Rush (2005), Sonic Rush Adventure (2007), and Sonic Colors (DS) (2010).

Sonic Adventure (1999) was Sonic Team's return to the character for a major game. It featured Sonic returning from vacation to find the city of Station Square under attack by a new, very powerful foe named Chaos, under the control of Dr. Robotnik (now more commonly known as Dr. Eggman). It was also the first Sonic game to feature a complete voice-over. Sonic Adventure 2 (2001) placed Sonic on-the-run from the military (G.U.N.) after being mistaken for a new enemy, Shadow the Hedgehog. Sonic Heroes (2003) featured Sonic teaming up with Tails and Knuckles, along with other character teams like Team Rose and Chaotix, against the newly rebuilt Metal Sonic, who had betrayed his master with intentions of world domination. Sonic the Hedgehog (2006) features Sonic in the city of water, "Soleanna," where he must rescue Princess Elise from Dr. Eggman while trying to avoid a new threat to his own life, Silver the Hedgehog. He is the only playable character in Sonic Unleashed (2008), in which he unwillingly gains a new personality, "Sonic the Werehog," the result of Sonic being fused with Dark Gaia's power. He gains strength and flexibility in exchange for his speed, and new friends including a strange creature named Chip who helps him along the way. In Sonic Colors (2010), Eggman tries to harness the energy of alien beings known as "Wisps" for a mind-control beam. Building on the gameplay used in the daytime stages of Unleashed, Sonic can harness these Wisps to gain temporary new abilities. The upcoming Sonic Generations (2011) will feature two playable incarnations of Sonic: classic Sonic, whose gameplay is presented in a style reminiscent of the Mega Drive/Genesis titles, and modern Sonic, who uses the gameplay style present in Unleashed and Colors.

Sonic and the Secret Rings (2007) features Sonic in the storybook world of 1001 Arabian Nights. A sequel, titled Sonic and the Black Knight (2009), continued the storybook theme, this time taking place within the realm of the Arthurian legend.

Sonic has also been featured in other games of many genres other than 2D and 3D platform games. These include Sonic Spinball, Sonic Labyrinth (1995), the racing games Sonic Drift (1994), Sonic Drift 2 (1995), Sonic R (1996), Sonic Riders (2006), Sonic Rivals (2006), Sonic Rivals 2 (2007), Sonic Riders: Zero Gravity (2008), and Sonic Free Riders (2010), the fighting games Sonic the Fighters (1996) and Sonic Battle (2003), the mobile game Sonic Jump (2005), and the role-playing video game Sonic Chronicles: The Dark Brotherhood (2008).

Video games such as Dr. Robotnik's Mean Bean Machine (1993), Knuckles' Chaotix (1995), Tails' Skypatrol (1995), Tails Adventure (1995), and Shadow the Hedgehog (2005) starred supporting characters of the Sonic series, although Sonic himself cameos in most of these titles.

Sonic has appeared in several crossover titles as well, including a playable appearance in Super Smash Bros. Brawl (2008), one of only two third-party characters (alongside Solid Snake) featured in the game. He appeared in the crossover party game Mario & Sonic at the Olympic Games as a Speed-type and in its sequel Mario & Sonic at the Olympic Winter Games as the fastest character. In the Adventure Mode (DS Version only), he partners with his former rival and friend, Mario, to stop their arch nemeses, Bowser and Dr. Eggman from ruining the Olympic Winter Games. Sonic is also a playable character in all three Sega Superstars titles.

Non-Sonic games

Sonic has made many cameo appearances in different games, most notably in other Sega games, such as being a power-up in Billy Hatcher and the Giant Egg, walking around the main hallway in Phantasy Star Universe on the anniversary of his first game's release (June 23), and appearing in the 2008 remake of Samba de Amigo (he appears in the background for the songs "Low Rider", "UN Aguardiants" and "Mambo #5"). He is also a playable character in Christmas NiGHTS into Dreams. Sonic has proved to be well liked among other publishers as well, making cameos in such games as Art Alive, Shining Force II, Clockwork Knight 2, Daytona USA, Crusader of Centy, Bug!, Rad Mobile, Ed, Edd n Eddy: Jawbreakers!, The Simpsons Game, The Incredible Hulk, and the video game adaptation of the film Tom and Jerry: The Movie.


The first animated series to feature Sonic was Adventures of Sonic the Hedgehog, in which he was voiced by Jaleel White.[2] The cartoon had a very comical take on Sonic and Tails' adventures battling Robotnik. Pierre De Celles, an animator who worked on Adventures of Sonic the Hedgehog, described the show as "fun and humorous."[3]

In the dramatic series Sonic the Hedgehog, Sonic was again voiced by Jaleel White.[4] He lives on the planet Mobius in Knothole Village, where he belongs to a band of Freedom Fighters that fight to free their world from the literally iron-fisted rule of the evil dictator Dr. Robotnik.

Sonic Underground featured the introductions of Sonic's triplet siblings Sonia the Hedgehog and Manic the Hedgehog, as well as his mother Queen Aleena, the four of whom were destined to defeat Robotnik and rule Mobius as the "Council of Four". Jaleel White returned to voice Sonic for the third time as well as voicing Sonic's siblings, with Samuel Vincent providing Sonic's singing voice.[5] This series is the only Sonic the Hedgehog series with European origins, as it was a co-production between the United States and France.

Additionally, there where two OVAs in Japan that conformed a single story which featured Sonic, Tails, Robotnik, Knuckles, and Metal Sonic. Sonic was voiced by Masami Kikuchi in Japan, and Martin Burke in the United States, where the two OVAs where treated as one unique, 1 hour long movie under the name of Sonic the Hedgehog: The movie.[6]

Sonic X, was an anime in which Sonic is teleported to Earth by Chaos Control, caused by the Chaos Emeralds (though the final season takes place in his own world). Here, he befriends a boy named Chris Thorndyke, and his infamous aquaphobia is made far stronger; in one episode where Sonic and his friends go on a cruise, Sonic is in a constant state of panic and desperately searches for a way to escape. In this series, he is voiced by Jun'ichi Kanemaru in the Japanese version, and by Jason Griffith in the English version.

Sonic: Night of the Werehog is a short film by Sega's VE Animation Studio, released to coincide with the release of Sonic Unleashed. In the film, Sonic and Chip enter a haunted house, and must deal with two ghosts trying to scare them.

Sonic's first comic appearance was in a promotional comic printed in Disney Adventures magazine (and also given away as a free pull-out with a copy of Mean Machines magazine), which established a backstory for the character involving the origin of his color and abilities and the transformation of kindly scientist Dr. Ovi Kintobor into the evil Dr. Ivo Robotnik. Numerous British publications, including "Sega handbook" Stay Sonic (1993), four novels published by Virgin Books (1993–1994) and the comic book Sonic the Comic (1993–2001) used this premise as their basis.

The American comics published by Archie Comics, Sonic the Hedgehog (1993–), Sonic X (2005–2008), and Sonic Universe (2009-) are based on the settings established by earlier animated TV series, the ABC "SatAM" cartoon, the Sonic X anime, and an expansion to the series, respectively. The former series is currently the second longest-running licensed comic series in the history of American comic books, second only to Marvel's Conan series (first issue released in 1970). In France two comic books named "Sonic Adventures" were published by Sirène in 1994.

Sonic has also been featured in two different manga. One series was simply called Sonic the Hedgehog, and featured a story about a normal boy named Nicky Parlouzer who can change into Sonic. The other series was a compilation of short stories and was separated into two volumes, the first being called Dash and Spin, and the other called Super Fast Sonic!!.

According to various official materials from Sega, Sonic is described as a character who is "like the wind":[7] a drifter who lives as he wants,[8] and makes life a series of events and adventures.[9] Sonic hates oppression and staunchly defends freedom.[10] Although he is mostly easy-going[8] he has a short temper[8] and is often impatient with slower things.[7] Sonic is a habitual daredevil hedgehog who is honest, loyal to friends, keeps his promises,[9] and dislikes tears.[11] He took the young Tails under his wing like a little brother,[12] but is uninterested in marital proposals from Amy Rose.[13] In times of crisis, he focuses intensely on the challenge[7] as if his personality had undergone an astonishing change.[9]

Sonic is known as the world's fastest hedgehog.[10] Sonic's greatest strength is his running speed, which is faster than the speed of light.[11] Many of his abilities are variations on the tendency for hedgehogs to roll into tight balls for protection with the addition of spinning his body. Since his introduction in 1991's Sonic the Hedgehog, Sonic's primary offensive maneuver is the basic "Spin Attack" (or "Sonic Spin Attack").[14] Later games in the series expanded on this basic attack and two of these enhancements have become mainstays of his: the Spin Dash which was introduced in Sonic the Hedgehog 2 and involves Sonic spinning on the spot before blasting off at full speed,[15] and the Homing Attack, officially introduced in Sonic Adventure, in which Sonic dashes toward a target in mid air.[10] Sonic's only weakness is that he cannot swim, sinking like a rock if plunged to a deep body of water.[11] However, he can overcome this by running on the surface of water.

When the seven Chaos Emeralds are collected in most Sonic games, Sonic can initiate a Super transformation into Super Sonic, a faster and invulnerable version of himself that can fly.[16] He can normally transform into Super Sonic with 50 Rings. While transformed, Sonic slowly loses Rings during the time he is in Super form (usually about one every second) and returns to normal when all the Rings are used up, usually incurring the loss of a life during a boss; the player can collect more Rings during this time to maintain Super form.Sonic is one of three characters to use the Super Emeralds.

Reception and legacy

As Sega's mascot and one of the key reasons for the company's success during the 16-bit era of consoles, Sonic is one of the most recognizable video game characters in the world. In 1996, Sonic was the first video game character to be seen in a Rose Parade. Sonic is also the first of two video game characters to have a balloon in Macy's Thanksgiving Day Parade (the other being Pikachu).[94]

Sonic was one of the three game characters inducted on the inaugural Walk of Game class in 2005, along with rival Mario and Link.[95] One of a class of genes involved in fruit fly embryonic development, called hedgehog genes, has been named "sonic hedgehog" after the character.[96]

As Sega's mascot, Sonic has also been used as a symbol for the company's various sponsorships. Between 1993 and 1997, Sega sponsored the JEF United Ichihara Chiba football team, during which period Sonic appeared in the team's uniform. During the 1993 Formula One championship, Sega sponsored the Williams Grand Prix team, which won the Constructors' Championship that year, as well as the team's lead driver, Alain Prost, winning the Drivers' Championship. Sonic was featured in the cars, helmets, and rival McLaren used to paint a squashed hedgehog after winning races over Williams.[97] The 1993 European Grand Prix featured a Sonic balloon and Sonic billboards, and the race's trophy was in the shape of a hedgehog. Sonic also appears on some versions of the willow video store logo.[98] Sonic is more recognizable for people than Mickey Mouse according to a poll.

On the 21 October 2008, Sonic was voted the most popular video game character in the UK with a 24% vote. His old rival Mario came second with 21% of the vote.[99]


Sonic has proven to be an extremely popular character. After the first game, Sonic the Hedgehog (1991) came out, Sonic became a well-known and very familiar character. After having been around only 2 years, he had already surpassed Nintendo's Mario in popularity according to a June 1993 Q-Survey in Gameplayers magazine. As a result of this popularity, he has been referred to in various parts of culture. Notably, Sonic recently made a number of cameo appearances in the Disney animated feature, Wreck-It Ralph.

  • In Sonic the Hedgehog CD, Sonic's fur was a lighter shade of blue.
  • There is a genome named Sonic hedgehog.[100]
  • In 1993, Sonic was the first video game character to appear in the Macy's Thanksgiving Day Parade (the second was Pikachu from the Pokémon franchise in 2001). Sonic had reappeared in 2011 as the lead of the parade, commemorating his 20th anniversary. He continues to be in the parade to this day.
  • In Sonic the Hedgehog CD, after standing still for three minutes, he will say "I'm outta here" and jump off the screen, after which the "GAME OVER" screen will appear.
  • In Sonic Adventure 2, Sonic Riders, Sonic Riders: Zero Gravity, Sonic Free Riders and Sonic Unleashed(while in Werehog form), Sonic wears different shoes.
  • When Sonic closes his eyes in every classic Sonic game, Sonic Adventure, Sonic Adventure 2 and all three Sonic Advance games, his eyelids are the same color as his arms and muzzle. After that, his eyelids were changed to blue. However, in one commercial, his eyelids were not blue, and in a Japanese commercial for a game, he had no eyelids at all (he blinks twice in the commercial, but his eyes are still open). This is alluded to in Sonic Generations, as Modern Sonic has blue eyelids while Classic Sonic has flesh-colored eyelids.
  • According to an interview on Sonic Central, Sonic does not know the whereabouts of Mighty the Armadillo,Ray the Flying Squirrel, Nack the Weasel, Bark the Polar Bear or Bean the Dynamite.
  • In Sonic Rush, if Sonic is tapped with the stylus during gameplay, he will clap, jump back and forth and continuously swing his arm clockwise as if he is exercising.
  • Originally, Sonic was intended to have visible fangs in his Japanese artwork, though they were removed when he was given a more Americanized design for his US artwork in order to "soften him up" slightly. Even though he still possesses fangs, they are only visible when he opens his mouth (this is mainly noticeable in Dreamcast titles such as Sonic Adventure and Sonic Shuffle, but became less obvious afterSonic Adventure 2). Previously, his fangs were supposed to be visible even when his mouth was closed.
  • Sonic's age has always been difficult to pinpoint. According to the Sonic Technical Files, he is 18, "but it's kinda hard to tell". Once Sonic Jam was released, his age appeared to be solidified at 16, but Sonic Channel had finalized it as 15. In Sonic Generations, Sonic's birthday was held, suggesting he has aged a year, but nothing official has been said.
  • In the Japanese versions of the games, Sonic proves that he knows more English than any of the other characters, as he is the only one who speaks English many times in the games. This may be due to the fact that the English language is considered "cool" in Japan, and it therefore makes sense to have the "coolest" character speak many English lines, as well as his Japanese voice actor wanting him to.
  • Sonic is the first character shown to utilize the Chaos Emeralds, transforming into Super Sonic in Sonic the Hedgehog 2.
  • In the 2011 Guinness World Records Gamers Edition, Sonic placed 10th in the "Top 50 Video Game Characters Of All Time". His rival, Mario, placed first, and Shadow had placed 25th.
  • Every time Sonic appears in a band, he is the guitarist.
  • It is possible that Sonic is able to move faster than the speed of light. This is implied in the DS version ofSonic Colors after Sonic scores an S rank on Omega's mission. When Omega collects data from Sonic, he says "At this rate, light speed will be exceeded", to which Sonic replies that light speed is slow and not a challenge.
  • Sonic has been chased by something numerous times in 3D games: a whale and a boulder in Sonic Adventure, a G.U.N. truck in Sonic Adventure 2, three large spiked wheels and a giant alligator in Sonic Heroes, a fire tornado and another whale in Sonic the Hedgehog (2006), a group of triceratops in Sonic and the Secret Rings, a black hole in the Wii version of Sonic Colors, and a helicopter and a truck in Sonic Generations. The black hole was the only thing that Sonic was not able to outrun.
  • Apparently, Sonic and his friends are able to breathe in space (as seen in several games), although he cannot breathe underwater without the support of bubbles.
  • All of the cars that Sonic has driven have been sports convertibles, similar to how Amy has only ever driven old-fashioned cars.
  • In 1996, Sonic was the first video game character to be seen in a Rose Parade.
  • The former NBA team "The Seattle SuperSonics" is often nicknamed "the Hedgehogs" as a reference to this character.
  • Between 1993 and 1997, Sega sponsored the JEF United Ichihara Chiba football team. During this period, Sonic appeared on the team's uniform.
  • Sonic, along with Knuckles and Dr. Eggman are the only characters who has retained their Japanese voice actor voicing him in all of the Sonic games since Sonic Adventure.
  • Sonic makes a cameo appearance in the Disney film Wreck-It Ralph, in which he is voiced by Roger Craig Smith. Eggman also makes an appearance in the film, thus marking the big screen debut for both characters. Much like Eggman, Sonic's design seems unchanged from his current design in the game series.
  • Whenever Sonic grinds, sparks fly, implying that his shoes (or at least their soles) may be made of metal.
  • Sonic was originally supposed to be colored teal, as shown in some of his concept art. He was changed to a darker blue color because the teal kept blending in with the sea in the background of Green Hill Zone.
  • Sonic likes to whistle as shown in several games. However, he whistles more in the Japanese versions of the games.
  • In Sega's other game Jet Set Radio one of the characters, Garam, wears a necklace with a skull on it. In an GamesTM interview with the art director of that game Ryuta Ueda, he stated that it is Sonic's skull in which Ryuta hinted that it's a skull of "another famous Sega character."
  • Miku Hatsune, a Vocaloid, who is the star of another popular Sega video game series, has an unlockable Sonic costume to use in gameplay to celebrate Sonic's 20th anniversary.
    • The costume was even designed by Yuji Uekawa, who is the artist of Sonic's current design.
    • She also sang a cover of Live and Learn on a special pre-order album of her game Hatsune Miku -Project DIVA- Extend to also celebrate his 20th anniversary.
  • At one point in Sonic Unleashed, Eggman called Sonic a "hedge-pig". This may be a reference to the fact that "pig" can be synonymous with "hog" and "hedgepig" means "hedgehog" in Shakesperean language.
  • Sonic appears to be able to juggle as was shown in Sonic Unleashed when Sonic was juggling the drained Chaos Emeralds.
  • Sonic is the inspiration for the Character Gears from the Anime Aoi Sekai no Chuushin de, which is coincidently a reimagining of the 'Console Wars' between Sega and Nintendo, with many other parodies of popular Sega and Nintendo characters appearing alongside Gears.
  • While initially thought to have no true "home", it is shown in Sonic and the Secret Rings that Sonic lives in a house, though it could be Tails' Workshop or similar.
  • In Sonic Unleashed, the Checkpoints, which calculate his speed (SPD) in-game, can clock Sonic going over 2,800 SPD; in comparison, the Light Speed Dash calculated 396 SPD. This shows that Sonic can move at speeds far greater than the speed of light.
