Twilight Sparkle is the main character of My Little Pony Friendship is Magic. She is a female sparkly unicorn pony who transforms into an Alicorn and becomes a princess in Magical Mystery Cure. She is the younger sister of Shining Armor, the youngest daughter of Night Light/Mr. Sparkle and Twilight Velvet/Mrs. Sparkle, the paternal aunt of Flurry Heart, and also the sister-in-law of Princess Cadance. At the beginning of the series, she and Spike, her best friend and assistant, move from Canterlot to Golden Oak Library in Ponyville to study the magic of friendship, and in Twilight's Kingdom - Part 2, she gains her own castle as part of her Friendship Rainbow Kingdom and is named the "Princess of Friendship"; "a whole episode in Season 5" is "devote[d]" to answering the question of whether she is "still going to use/live in her library." Twilight Sparkle represents the element of magic. Before becoming a princess, she regularly sends friendship reports to Princess Celestia she is voiced by Tara Strong.
Lauren Faust was inspired to create Twilight Sparkle by her childhood toy G1 pony Twilight. Faust's early design of Twilight shared a similar color scheme and cutie mark with the G1 Twilight, who appears in the pilot episode "Rescue at Midnight Castle". Twilight Sparkle's color scheme was later changed to that of the G3 Earth pony Twilight Twinkle, with a slightly different mane and tail, but Lauren Faust said that Twilight originally had dark blue hair with a light blue stripe; Twilight Sparkle was called "Twilight Twinkle" in early scripts for the sho w. G1 Twilight teleports by wishing, and Twilight Twinkle likes to watch fireflies; Twilight Sparkle shares aspects from both of these ponies, with her ability to teleport and her occasional stargazing. Though she is much more studious and possesses more powerful magical abilities, she also shares a number of personality traits with the G1 Pegasus Wind Whistler, such as her tendency to rely on logic rather than instincts and her habit of using more advanced and technical terms. She additionally shares some personality traits with the G1 pony named Bright Eyes. In a 2008 sketch for the series bible, Twilight's cutie mark resembles that of the character Moondancer from earlier My Little Pony generations. Lauren Faust had planned for Twilight to acquire the power of self-levitation "at some point." Following Faust's departure from the show, Twilight has used this power in the season three episodes The Crystal Empire - Part 2 and Magical Mystery Cure. As an Alicorn, Princess Twilight is a little taller, her neck is more curved, and her horn is a bit longer than when she was a unicorn.
Love of Books
In Friendship is Magic, part 1, Twinkleshine says Twilight is more interested in books than friends. Even after Twilight becomes good friends with the rest of the main characters, she continues to read and consult books. For example, she confidently joins a marathon after reading several books about running in Fall Weather Friends. She is also very knowledgeable about Equestria's history, as seen in such episodes as Luna Eclipsed and Testing Testing 1, 2, 3.
Twilight tries to be rational in unfamiliar situations. During the investigation in MM Mystery on the Friendship Express, Twilight tells Pinkie Pie to stop making wild accusations, and they work together to find clues and solve the mystery. However, Twilight can lose her cool under stress. In Swarm of the Century, she hysterically suggests building a replica of Ponyville in less than a minute before Princess Celestia can see the damage done by the parasprite infestation. Twilight tends to be skeptical of unproven claims, such as her friends' belief that Zecora is an evil enchantress in Bridle Gossip, and Pinkie's "Pinkie Sense" in Feeling Pinkie Keen.
Knack for Organization
Twilight shows her knack for organization in Winter Wrap Up. When the Winter Wrap Up becomes inefficient and uncoordinated, she organizes the teams and ensures that winter is wrapped up on time. Mayor Mare gives Twilight the official title of "All-Team Organizer". Twilight also uses her organization skills in the episodes Lesson Zero and It's About Time.
In the episode Twilight Time, Twilight takes time each week to teach the Cutie Mark Crusaders various skills. She attempts to teach Sweetie Belle to use the telekinetic component of her magic, Apple Bloom how to make botanic growth potions and Scootaloo how to strip and reassemble various types of scooter and cycle. Twilight is overjoyed when she thinks the other classmates also want to learn new things, but is disappointed when she finds out that they merely want to spend time with a local celebrity. Twilight's ability as a teacher is proven in that she succeeds in teaching all three Crusaders the skills she intended to teach them. They all demonstrate a high degree of aptitude at the end of their lessons. Twilight attempts to teach Rainbow Dash the history of the Wonderbolts, but her methods of study prove futile when Rainbow Dash acts as a class clown in Testing Testing 1, 2, 3.
Twilight is exceptionally talented at magic. In a flashback in The Cutie Mark Chronicles, Princess Celestia tells Twilight that she has never seen a unicorn with so much raw ability.
As talented as Twilight is, her spells occasionally misfire or fail.
- When she casts a spell on the parasprites in Swarm of the Century so they won't eat food, they begin to consume items which aren't food, and subsequently destroy Ponyville.
- When she tries to assist with Winter Wrap Up by animating a plow with a "come-to-life" spell, she loses control of it and makes a mess.
- In The Return of Harmony Part 1, she tries to reverse Discord's strange effects with a "fail-safe spell", but it fails.
- In the episode Magic Duel, she has difficulty performing an age spell, which she says is only for "the highest level unicorns".
In the first season, Twilight's horn usually glows white or the same hue as her coat, and the objects she is manipulating glow white, lavender, or pink. When she manipulates multiple objects at once, several other colors are used as well, for example in the gem-finding scene in A Dog and Pony Show. Starting with the second season's third episode, Twilight's magic is uniformly depicted using a pink glow.
