Twilight Sparkle one of the main character of My Little Pony Friendship is Magic. She is a female unicorn pony who transforms into an Alicorn and becomes a princess in Magical Mystery Cure. She is also the younger sister of Shining Armor and sister-in-law to 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; "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 herself, she regularly sends friendship reports to Princess Celestia.
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 show. 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, Twilight is a little taller, and her horn is a bit longer than when she was a unicorn
Depiction in the seriesEdit
Twilight lives in Canterlot until Princess Celestia sends her and Spike to Ponyville to oversee the preparations for the Summer Sun Celebration and make some friends. Twilight befriends the rest of the main characters, and remains in Ponyville to continue to study the magic of friendship. In A Canterlot Wedding - Part 1, Twilight says that Princess Cadance was her foalsitter when she was a filly.
Twilight tells the Cutie Mark Crusaders how she got her cutie mark in The Cutie Mark Chronicles. She says that when she was a filly, she studied magic on her own and wanted to attend Princess Celestia's School for Gifted Unicorns. At the entrance exam, Twilight was told to use magic to hatch Spike's egg, but her magic got out of control when she was startled by Rainbow Dash's sonic rainboom. Princess Celestia took note of her magical abilities and made Twilight her personal protégé. In Magical Mystery Cure, Twilight Sparkle completes an unfinished magic spell with her deep understanding of friendship. Princess Celestia tells her that Twilight is ready for the next stage of her life, and she is transformed into an Alicorn and crowned a princess. Princess Twilight Sparkle becomes the ruler of the Friendship Rainbow Kingdom in the season four episode Twilight's Kingdom - Part 2.
Love of booksEdit
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.
Knack for organizationEdit
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 shows a notable talent for organization and making checklists in the episode Lesson Zero and It's About Time.
Twilight Sparkle 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".
Twilight confidently using her magic S2E24
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.
Hot air balloonEdit
Twilight and Spike in their hot air balloon. Twilight rides a purple hot air balloon in the title sequence, and uses the same balloon to fly with her friends to Cloudsdale for Rainbow Dash's competition in Sonic Rainboom. In The Return of Harmony Part 2, the ponies use it to fly with Fluttershy in order to capture the brainwashed Rainbow Dash. The balloon is also used on other occasions.
For the first three seasons of the show, Twilight possesses a crown containing the element of magic. She receives it in Friendship is Magic, part 2 upon defeating Nightmare Moon. The crown is studded with sapphires and a magenta star-shaped gem shaped like like Twilight's cutie mark.
After Twilight becomes a princess in Magical Mystery Cure, she receives a different crown with the element of magic embedded in it. It is a lighter shade of gold, no longer has sapphires, and rests horizontally, not vertically, on Twilight's head.
Twilight relinquishes her crown when she and her friends restore the Elements of Harmony to the Tree of Harmony in Princess Twilight Sparkle - Part 2. At the Summer Sun Celebration, she wears a new crown, which has the same shade of gold just like and looks completely different from her element of magic crown. It has more of a "classic" crown shape, with each point studded with a small magenta jewel. It becomes her regular crown for the rest of the season, as seen in Trade Ya, Equestria Games, and Twilight's Kingdom - Part 1.
Twilight's parents first appear in The Cutie Mark Chronicles. In a flashback, they excitedly nod their approval when Princess Celestia offers to make Twilight her apprentice. In A Canterlot Wedding - Part 2, they attend Shining Armor's wedding and are moved to tears. They attend Twilight's coronation in Magical Mystery Cure. Twilight Sparkle's mother resembles the notable G1 pony Twilight in My Little Pony Special, with her hair style similar to Twilight's. Twilight Sparkle's father resembles the G1 pony named Nightlight, but gender-swapped.
Twilight reveals that she has an older brother, Shining Armor, in A Canterlot Wedding - Part 1. She sings B.B.B.F.F. (Big Brother Best Friend Forever), a song about their close bond and how much she misses him after she moves to Ponyville. Shining Armor, though extremely busy with his duties around the Crystal Empire, still has time for his little sister, whom he calls "Twily".
Twilight reveals that Princess Cadance was her foal-sitter when she was a filly. At the end of A Canterlot Wedding - Part 2, Twilight becomes Cadance's sister-in-law when she marries Shining Armor. Twilight enjoys spending time with Cadance as seen in Three's a Crowd when Cadance comes to visit her.
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. She is also initially overjoyed when she thinks that all their classmates also want to learn new things and is very disappointed when she finds out that they merely want to spend time around 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 as Rainbow Dash acts as a class clown in Testing, Testing, 1, 2, 3.

Perfect Day for FunEdit
Twilight reappears in Perfect Day for Fun, where she spends some time with Fluttershy at the Canterlot High springtime carnival. At one point, she gives Fluttershy a Discord plushie, but Fluttershy smacks it with a Whack-a-Mole hammer. She and Fluttershy spend most of the short trying to find the others. They finally reunite at the photo booth. The friends all take some photos, but then Twilight tells them it is almost showtime and they take off to perform on the stage. In one photo montage, Twilight and Applejack drag a crying Fluttershy into a haunted house.

Depiction in comicsEdit
Comic micro 1 page 1 Twilight in My Little Pony Micro-Series Issue #1. In the IDW comics, Twilight Sparkle is depicted as a wingless unicorn even in comic books released as recently as November 13, 2013; IDW editor Bobby Curnow had not heard about Twilight becoming an Alicorn princess until the public announcement in late January 2013, and wrote on the IDW Publishing Forums on May 27, 2013 "As of right now, I have the same knowledge about Princess Twilight as any of you guys. So it's not something I would want to touch in the comics until after I better see how Season 4 handles it." Twilight is depicted as an Alicorn in the preview of Little Brown's chapter book Twilight Sparkle and the Crystal Heart Spell included in both IDW's My Little Pony: Friendship is Magic Issue #6 and My Little Pony Micro-Series Issue #3, on a display shown on My Little Pony Micro-Series Issue #8 New York Comic Con exclusive Comics World cover RE, on a sketch card bundled with one of the deluxe hardcover releases of The Return of Queen Chrysalis and shown in My Little Pony Art Gallery page 15, on a My Little Pony: The Magic Begins cover, on My Little Pony: Friendship is Magic Issue #12's Hot Topic cover, and on a My Little Pony Micro-Series Volume 1 cover. She is depicted as an Alicorn princess in the comics from My Little Pony: Friendship is Magic Issue #13 onward; Curnow wrote on the IDW Publishing Forums in late September 2013 "We've got the season 4 scripts, and I've read a good chunk of them, and feel like I have a good idea how alicorn Twilight will be handled", and wrote on The Round Stable forums in mid-November 2013 "If we're referencing an issue that happens in the past, there's no reason why we can't show wingless Twilight. It's not like the past has been erased, it's part of her history."
