Twilight Sparkle (Sci-Twi)

Twilight Sparkle ' s human counterpart appears and is mentioned throughout the My Little Pony Equestria Girls film series. She is a student at Canterlot High School, a former student of Crystal Prep Academy, and the owner of Spike the Dog. This version of Twilight looks considerably different from her pony counterpart as she wears thick black glasses and her hair in a bun. She is named Sci-Twi in some merchandise and other depictions. Her alter ego, Midnight Sparkle, briefly serves as an antagonist in My Little Pony Equestria Girls: Friendship Games.

Equestria Girls: Friendship Games
In the third Equestria Girls film, Twilight's human counterpart is revealed to be attending Crystal Prep Academy and is a member of the Wondercolts' rival, the Shadowbolts. This version of Twilight is portrayed as being rather awkward and curious.

Throughout the film, Twilight attempts to track and measure strange energy readings at Canterlot High, recording all of her findings on a tack board in a secret room at Crystal Prep. She gathers this research in hopes of being accepted into an independent study program, and she only competes with the Shadowbolts to do further observations of the weird energy.

Twilight carries a device intended to detect the strange readings. However, it also drains magic away, causing each of the Rainbooms to lose their ability to pony up. In addition, it causes dimensional rifts to appear throughout the Games. When Principal Cinch discovers this, she pressures Twilight to release the magic from her device to win the Games. Once she does, the magic engulfs her, and she transforms into a monstrous creature obsessed with magic. After her transformation, Twilight uses her powers to open additional rifts to Equestria. Using Twilight's device, Sunset channels the released magic to transform herself. Following an explosive battle, Sunset offers Twilight her hand in friendship, and Twilight accepts. Twilight apologizes for all the trouble she caused, and Sunset and her friends forgive her.

Later, Twilight decides to forego her independent study application and transfer to Canterlot High to learn about the magic of friendship. At the end, Princess Twilight Sparkle from Equestria appears out of the portal, stunned to see her human friends joined by a girl who looks like her. Human Twilight only nervously waves "hello" to her pony counterpart.

In the film's alternate ending, Twilight stays at Crystal Prep, and she and Spike are on much friendlier terms with the Shadowbolts.

Software

Friendship Games description
''Meet Crystal Prep Twilight Sparkle, the Twilight Sparkle who has always lived in Equestria Girls world – she just goes to another school! You'll recognize this Twilight Sparkle by her signature glasses. She maintains the same personality traits of the Twilight we know from the MLP world, but she has yet to learn about the magic of friendship''

Merchandise
Twilight is featured in various Friendship Games doll merchandise, sometimes under the name Sci-Twi. A "Sporty Style" doll of Twilight comes with a bow and arrow. Twilight's description on the back of her Sporty Style doll's packaging reads, "Study the competition!" A casual-clothed doll of Twilight is included in 2-packs with Flash Sentry and Rainbow Dash. A Midnight Sparkle doll shown at the 2014 New York Toy Fair has also been released.

A doll of Sci-Twi with pony ears and a lab coat was shown at the 2015 San Diego Comic-Con. This doll comes with a miniature Spike the Dog figure and a school locker.

Human Twilight appears as a pony in Equestria on the fan-designed WeLoveFine art print "Girls in Equestria".

Personality
Like her pony counterpart, human Twilight is well-spoken and highly intelligent. She holds a great interest in knowledge and science, being able to assemble intricate scientific devices and solve complex mathematical equations, and her intellect rivals that of Sunset Shimmer. Unlike pony Twilight, however, human Twilight is socially similar to how she appears in the first episode. She is a bit of a wallflower, acting very awkward and timid around others, especially the standoffish students of Crystal Prep.

Twilight lacks self-confidence when under extreme external (especially social) pressures. During the archery competition in the Tri-Event Relay in the Friendship Games, she is so affected by performance anxiety and Sour Sweet's anger at her poor aim that she begins to cry and her legs threaten to collapse under her.

When transformed into Midnight Sparkle, Twilight becomes selfish and malicious, consumed with desire to learn everything about magic even at the cost of her entire world.
