Jeffy is one of the main characters from a plush web series called SuperMarioLogan on YouTube. He used to be babysitted by Mario and Rosalina since Mario the Babysitter!, but now is the adoptive son for the SML Family.
He is the oldest child of Nancy and Jacques Pierre François, and the older brother of Feebee and Scooter, but since his biological father Jacques died and Nancy went to prison in "Jeffy's Parents!", he and Scooter are now the adoptive children of Mario and his wife, Rosalina. Despite this, he still has his younger cloned brother, Scooter, who is currently wandering around outside Mario's house somewhere.
The things that he does in his everyday life is annoying and torturing Mario, hanging out with Junior and his friends, causing trouble, hating school, throwing a plate of green beans, eating chocolate cake, and more.
Physical Appearance[]
Jeffy is somewhat different than the average teen, with a tall and slim posture. He wears a blue bicycle helmet (with black messy hair under it), usually has a pencil shoved up his nose, has blue crossed eyes, along with a yellow T-shirt that reads "Jeffy" on it which his mother wrote so he would not forget his name. Apparently, when a different word is written on it he thinks his name is that word as seen in Jeffy’s shirt when Junior wrote “poopy butt” on it. Jeffy thought it was his actual name to the point of losing 100,000,000 dollars because of it.
He wears short dark blue jeans with a Pamper diaper (which, according to Jeffy himself, is on the outside so it doesn't get dirty), which he occasionally spanks. He wears black Adidas sneakers. His biological appearance seems to be mixed between his parents, with his blue eyes inherited from his mother and his dark brown hair inherited from his father. His face is oval-shaped with two teeth and around the nose, along with two eyelashes and a unibrow.
History[]
Jeffy was born as Jeffy Jeffy François in a porta-potty at 7 Jeffy Street, Paris, France, on August 21, 2004, to prostitute Nancy Pierre François and painter Jacques Pierre François. They are both of French descent, but Jacques is full-blooded French. Due to not being raised properly, as well as being abused by his mother, he acts really dumb and even still wears a diaper over his pants. His mother also forced him to stick a pencil in his nose for unknown reasons. He also lost his toes through an unknown incident. This was seen in Jeffy Breaks His Leg!
Jeffy moved to Florida in 2005 with Feebee, his little sister, who was later killed in a bike accident as Nancy took her helmet to use as an ashtray. Her death was the reason why Jeffy always wears his helmet wherever he goes.
After Nancy had enough of his antics, Jeffy was dropped off at Mario and Bowser's apartment. Jeffy lived with Mario and his family in the apartment (Causing havoc around the house, especially towards Mario), although the latter hated him before being evicted from the apartment and having to relocate to the new house.
After his wealthy father committed suicide and willed his money to Jeffy, Nancy returned to reclaim Jeffy in order to receive Jacques' money when Jeffy turns 18, but was arrested and incarcerated for child abuse, prostitution, and several other crimes. After Nancy's arrest, Mario chose to officially adopt Jeffy as his son and the two now begin to bond every day.
As of today, he is still Mario’s now adopted son and spends his days annoying and bothering the latter, playing with Junior and his friends and continuing to cause trouble and mayhem.
Since during 2020, Jeffy has began to become smart and helpful such as the time when he became a detective to help Mario getting out of jail and the time when he watch a scary movie with Mario, and Mario keep lying about the strawman movie while Jeffy proves he is lying. But despite this, Jeffy still loves his family. He is also shown to be heartless, as in Jeffy the Doughnut King!, where Brooklyn T. Guy tells him that his boss was dying because he hadn't eaten a donut, but he didn't care and he just replied by saying he was bored.
Personality[]
Jeffy's main characteristic is being mentally handicapped. Starting off as an innocent baby-like boy before evolving into a downright slightly ditzy person who swears like a sailor, explodes in anger at any slight against him, and knowing a lot about perverted acts for someone his age, Jeffy's personality has gone through more changes than any other character in the SML series. Over time, he has matured and does not annoy Mario and Rosalina as much as he used to. He barely swears anymore and only acts more like a troublesome child. He is also known to be very strong, possibly one of the strongest characters in SML, as he tends to beat up bullies, hit balls really hard, and has a high pain tolerance.
He has a habit of spanking his diaper placed outside of his pants as well as soiling his pants often. When he is called a "bad boy" or in some cases a "retard", he tends to have a breakdown by throwing his head onto any surface, but calms down when he is called a "good boy" (this is no longer the case after the events of Jeffy Loses His Pencil!). However, his breakdowns can become extreme and violent, which involves curse words and being rude towards Mario and Rosalina. He also flips his desk in "First Day Of School!" because the teacher assigned a 10-page essay that was due the next day and cusses (mostly the F-word) at Jackie Chu, saying "ARE YOU F***ING HIGH?!", He often says "Why?" whenever someone tells him what to do or what not to do. He even keeps saying it whenever someone answers him. He also has a habit of calling things he likes "pee-pee." He also often says "I don't even know" when asked questions.
He likes to put his "pee-pee" in various objects, especially Cheerios boxes, to the point where he somehow even impregnates one and develops romantic feelings for it.
He deeply resents Bully Bill, who picks on him and subsequently beats up all the time, but the person he hates even more is his teacher, Jackie Chu, his archrival and most hated person in the world.
He is also afraid of trivial and ridiculous things, such as animals, toilets, snow, ostriches, a flu shot, and the number 7. Based on characteristics, it is suggested that he has mental retardation. His mother delivered him to Mario because she did not love him for unknown reasons (according to Jeffy).
Despite his mental and intellectual disabilities, Jeffy has shown traits of intelligence, but in a retarded way at times, such as in Jeffy's Homework! when he reasoned that the equation 8-4=8, since they are taking 4 out of the equation, even going on a profanity-laced rant as well as getting very smart over the years as Mario thinks he will not notice anything or remember anything but he does so he is not very dumb anymore. He is also an extremely skilled painter, a trait passed down from his father. He has also shown signs of intelligence as in Jeffy Gets Ran Over, where he remembers everything that happened to him after getting knocked out by Mario's car, as well as knowing that Mario is the one that hit him.
Jeffy has shown to be demanding, even more than the level Junior displays, as seen in Jeffy's Bedtime!, where he demands that Mario and Rosalina make his green eggs and ham, "Jeffy Gets Potty Trained!" when he demands that Rosalina give him marshmallows instead of peas, "The Hitman!", where he wanted Jello after Mario gave him green beans, he refused to eat his McDonald's Chicken Nuggets because he wasn't given 20 toys and threw them away, in "Locked Out", where he demanded chocolate cake, cried when Mario didn't give him it and locked Mario out to enjoy the cake, especially in front of Mario, and in "Jeffy Gets Help", when Jeffy yells, screams, and throws a temper tantrum because Mario said that he would not watch SpongeBob SquarePants.
Jeffy is shown to enjoy playing pranks, as seen in "Jeffy's Cellphone!", where he prank calls several places, including an employee named Josh and a prostitute, resulting Rosalina thinking Mario is cheating and beating on Mario, and in "Shrek The Babysitter!", where he locks Shrek in the bathroom with the help of Bowser Junior. Both of these videos shows that he seems to be less unintelligent, causing many fans to think that this could be a normal version of Jeffy, despite all of his intelligent moments in the series. Some people Who think Jeffy pretends to be retarded. When his real mother Nancy tried to claim him back, Jeffy begged Mario to let him stay and promised to be a good boy (and kept his promise by not playing the cat piano when he went back inside), indicating that he loves Mario very much. Jeffy's obsession with swearing may be from his mother and the way she acted in front of him and treated him.
Despite of all this, he is generally more on the friendly side and the bad things he do is mostly due to his unintelligence. He has his fair share of good deeds that battle the evil ones, such as being considerate of to Hansel in three episodes. He is most likely misunderstood after suffering pain from his biological mother and witnessing his twin sister and biological father's death, which might explain his outburst problems.
Although he is unintelligent, he was shown to be an adult to Mario in some episodes such as the time when he caught Mario spilling water all over his bed and Mario wanting to play with his Lego rather than eating his food. And some times he does not like to believe people like in The Halloween Heist.
Controversy[]
Jeffy has proven to be the most controversial character of SuperMarioLogan. Many fans complained about him by saying that he was offensive, due to him being a stereotype of mentally disabled people. Logan has responded to these claims by saying that Jeffy is meant to be funny like Chef Poo Poo, not mentally disabled.
Since Jeffy's Bad Word! and Locked Out were released, Jeffy received an immense hatred from older fans, because of him saying the word "f-----" [censored] and being an absolute jerk towards Mario. Despite this, he is also known to have a diehard fanbase, which consists of children and young teenagers, adding even more controversy. After Jeffy's Parents!, fans started to sympathize and like him even more as he had been abused by his mother, Nancy, though some fans still hate Jeffy
Jeffy's popularity grew when Jeffy The Rapper! and Jeffy's Fidget Spinner! were released, which made many young children grow fond of Jeffy and basically worship him. Later, the children constantly demanded more videos featuring him and would dislike any video that does not feature him. This caused many older fans to fuel their hatred for both Jeffy and his fanbase. In Jeffy's Fun Day!, he received a poor reception.
In December 2017, a seven-year-old boy attempted to hang himself with a noose the way Jeffy almost did in his emo form in the now-deleted Jeffy's Tantrum!. The mother of the child discovered this and reported in the news station called The Sun after he attempted to do the act. The article can be viewed here. Logan then apologized and assured that his videos are not to be imitated; despite this, YouTube started demonetizing and age-restricting all of his videos. A few months later, second-graders and third-graders watched Jeffy The Rapper! and were disciplined after mimicking him (mostly by boys).
As of late 2018 and early 2019, SML lost many of their viewers due to the fact that Jeffy became incredibly overused and popular with young children, even though his actions and language are inappropriate for their age. However, now that Jeffy has toned down his swearing and acting inappropriately, no one seems to hate him as much and started to enjoy him more. But that's not to say that people no longer hates him, as there are still some people who do.
Relationships[]
Mario (SML)[]
Before Season 9, Mario and Jeffy formerly had bad blood against each other. Mario also hates his stupidity and how he can annoying sometimes. Although he is protective, such as when he lost Jeffy where he eats, and when Jeffy had a gun, he was looking and telling Jeffy to put the gun down (even though he should've been happy because he wouldn't have to deal with Jeffy anymore). He also shot Jeffy with a Nerf gun in Bowser Junior's Nerf War! In Where's Jeffy?, Mario abandoned Jeffy at the park. However, when Jeffy turned smart, Mario liked him very much and told him that he was proud that he was his son, and was sad when he turned back to normal due to him losing the international world smart person contest.
However. in the episode Jeffy's Parents!, it showed Mario's good side on Jeffy and officially adopts him. He missed Jeffy when his mother came to take him home. Mario called the cops on her and took her to Jail for Child Abuse, Prostitution. After learning about Jeffy’s tragedy and how his former father was a millionaire and killed himself and give all his money to him, Mario now officially adopts him and they are now officially father and son.
Despite their differences, Mario and Jeffy still love each other deep down, and can't live without each other, developing a relationship similar to Bowser Junior and Chef Pee Pee or a relationship similar to Bowser Junior and Bowser.
Bowser Junior (SML)[]
Considering how widely popular and relevant both characters are, Jeffy and Bowser Junior are very good friends. They enjoy hanging out with each other and making a good team. When Jeffy and Junior met for the first time in Bowser Junior's Game Night 3, Junior called Jeffy awesome for surviving a game of Russian Roulette. Jeffy was indirectly also the reason for Mario and Junior permanently recognizing each other starting from that episode, and he also seems to like Junior.
As of recently, both Junior and Jeffy seem to get along more, as shown in Shrek The Babysitter! and Smart Jeffy. Junior even caused the main plot elements of Smart Jeffy and Jeffy Loses His Teeth!, wherein he made a jump from a trampoline and hit a table in the former, and accidentally knocked one of Jeffy's teeth out with a T-ball bat in the latter. However, Jeffy and Junior have had major conflicts with each other in the past, such as Junior being responsible for the death of Jeffy's children Puss Hole and Puss Hole 2 in Jeffy's Kids!, a deleted video. Despite this, they generally seem to be on a good term regardless. After Jeffy and Junior skip school, where Jeffy agreed with junior to skip school to go mini-golfing.
He and Junior are now best friends to the point where junior plays with him more than Cody and Joseph. In Jeffy and Junior's Big Heist, Jeffy helped Junior retrieve Charleyyy’s underwear and getting him to sign it as they both disguised as people from corporate to make him sign it. He and Junior are now best friends.
Cody[]
Cody and Jeffy are good friends. Although sometimes Jeffy can get on Cody's nerves, Cody doesn't mind this. Cody finds Jeffy extremely stupid as seen in The Test! when he fails to teach Jeffy proper math. Along with Bowser Junior. Cody sometimes finds opportunities to rape Jeffy, it is unknown if Cody was able to rape Jeffy in The Remote! as Cody sometimes find's Jeffy attractive.
Nancy[]
Debuting in Jeffy's Parents!, Nancy is shown to be very abusive towards her son, to a much higher extent than Mario was. Nancy acted as she cared about him when people were around, but when they were alone she would always beat him. Nancy eventually got arrested and Jeffy ended up getting adopted by Mario.
Later in Jeffy's 18th Birthday!, Jeffy was taken after showing up in the field to rescue Marvin and him and the cops started chasing the van to get Jeffy. While they're still chasing them, He tries to resist and tries to get the gun, but his mother holds her gun closer to him. Once, Screwball says about losing their gas, Jeffy snatches Nancy's gun and shoots her in the face, Jeffy jumped out of the van as Simmons cause it to explode. Jeffy became very happy as his abusive mother is finally dead.
Rosalina (SML)[]
Jeffy and Rosalina seem to get along well, going to where Rosalina copies Jeffy a lot. Jeffy usually calls Rosalina "Mommy" just like how he calls Mario "Daddy." Rosalina acts like a deep motherly figure to Jeffy, to the point of sometimes caring more about Jeffy, and calling Mario out whenever he abuses Jeffy, even breaking up with Mario when he heartlessly lets Jeffy go with Nancy.
She most likely does this as she wants to be the mother Jeffy was “supposed“ to have as Nancy abused him which makes Rosalina mad as she absolutely hates to a point at even trying to break up with Mario as he tried to give Jeffy back to Nancy.
He will yell at her occasionally if he does not get his way, but despite this, He mostly loves her as a mother. Rosalina is more loving and caring towards Jeffy to the point where she acts as a motherly figure and calls Mario off whenever he gets angry at Jeffy.
Jacques Pierre François[]
Not much is known about Jeffy's relationship with his dad, world-renowned French painter Jacques Pierre François, who had faked his death to make his paintings more valuable. Due to the fact that Jeffy's "IF LOST" paper contains Jacques's name and address information, this could imply that Jacques used to care about Jeffy. Jeffy has also claimed that he learned basic French from his father.
However, in Jeffy's 18th Birthday, Jacques told Jeffy to "f**k off" on live television and left him with none of the fortune. As of now, Jeffy is completely unaware of his father's contempt towards him.
Feebee[]
In Jeffy's Sister!, it was revealed that Jeffy has a sister named Feebee. Jeffy and Feebee are very similar in character, with nearly exactly the same traits. They can even communicate with each other through diaper patting. However, it was revealed in Jeffy's Sister Returns!, that Jeffy's sister Feebee was killed when she got hit by a truck while riding a bike and died back in 2015.
Brooklyn T. Guy[]
Most of the time, Brooklyn T. Guy doesn't seem to mind and cares about Jeffy, as shown in episodes such as Mario The Babysitter!, Jeffy's Bad Word!, Jeffy Goes To The Zoo! and Locked Out. But he still likes him as a friend. However, in the third episode of Who Wants To Be A Millionaire?, Brooklyn Guy is shown to get annoyed with Jeffy's behavior and is sometimes Jeffy’s Arch-Rival
Chef Pee Pee[]
Jeffy seems to like Chef Pee Pee, but like Mario, Chef Pee Pee doesn't seem to have any patience for Jeffy. For instance, he got annoyed with when Mario and he were trying to get to eat his green beans. Chef Pee Pee also seemed upset when Jeffy ruined the pencil cake Chef Pee Pee made for him. When Chef Pee Pee babysat Jeffy, he was so annoyed by Jeffy's shenanigans to point that he would've killed Jeffy if Mario hadn't shown up in time.
Black Yoshi[]
Jeffy doesn't seem to have much of a relationship with Black Yoshi. The two have only unofficially met in one video Jeffy's Mistake! but the events in that video are a dream. However, Black Yoshi and Jeffy have mentioned each other many times in future episodes, like Jeffy's Piggy Bank! and they seem to rather have more of a positive relationship rather than a negative one.
Shrek (SML)[]
Jeffy and Shrek don't seem to have a good relationship because Jeffy locked him in the bathroom and ate his cheesecake along with Bowser Junior, so Shrek locked both of them in the bathroom with the toilet clogged.
Toad (SML)[]
Jeffy and Toad seem to be rivals when it comes to the rap game, however outside of rapping, for the most part they seem to be on good terms, even if they don't have much interaction outside of rapping.
Bully Bill (SML)[]
Jeffy is a frequent target for Bully Bill. However, Jeffy does not take it lying down, and as he turns against Bully Bill's bullying on him with extreme physical violence. Despite the number of beatings he has taken, Bully Bill never learns his lesson because he is an idiot.
Bowser (SML)[]
Jeffy and Bowser don't seem to have a good relationship due to how Bowser accidentally gave Jeffy the flu by coughing in his mouth in Jeffy's Flu Shot!, how Bowser acted harshly towards Jeffy in The Competition! and how Bowser mistook the shock collar remote for the TV remote and repeatedly used it, shocking Jeffy and indirectly framing Mario in Jeffy's Punishment!, as well as how Jeffy was paid by Mario to break Bowser's trophy in Jeffy and Junior Sneak Out!. Jeffy, however, did congratulate Bowser when he won Charleyyy's underwear in Jeffy and Junior's Big Heist!, but other after that, for the most part they seem to be on good terms, even if they don't have much interaction with each other.
Jackie Chu[]
Jeffy and Jackie Chu are archenemies. They first met in the First Day Of School!. Jackie Chu never like Jeffy because of his bad behavior and Jeffy hates Jackie Chu because the latter yells at him, kicks him out of class, and makes fun of him by calling him a bitch. Although the two hated each other all the time, but on extremely rare occasions, they kind of have a good relationship with each other, two examples that have the two being on good terms is in The Baby Project! where Jackie Chu gives Jeffy and Junior an A for killing the baby and in The Science Fair! where he gives Jeffy an A+ for melting crayons on his rainbow popcorn project.
Trivia[]
- Jeffy's catchphrase "ARE YOU FUCKING High!" could be inspired by the 2008 comedy movie Step Brothers. The movie is about two step brothers named Brennen and Dale who are adults but act like there little kids, in one scene Brennen and Dale's parents ground them by not letting them watch TV for a week after the two get into a fight witch made Brennen mad and shout "ARE YOU FUCKING HIGH!"
