Twilight Sparkle (Sci-Twi)

Twilight Sparkle is one of the main characters from the My Little Pony - Equestria Girls franchise.

Princess Twilight Sparkle's human counterpart, an asocial studious bookworm attending Crystal Prep Academy, the rival school to Canterlot High. During the events of  Friendship Games, Twilight meets the Rainbooms when she attempts to study their Equestrian magic, to disastrous results. Bonding with the group during the games and never feeling accepted at Crystal Prep anyway, Twilight transfers to Canterlot High and continues her friendship with the girls.

In the Heroes Coalition fics, Twilight attends the Vanguard Academy as a student.

Appearance
Twilight has a pale, light grayish mulberry skin tone, she has moderate violet eyes and she has a long, moderate sapphire blue with moderate violet and brilliant rose streaks tied in a high ponytail. She wears a blue blouse with purple stripes, white collar and red ribbon tie, a purple high-waist skirt, blue socks and blue rubber shoes. She also wears black framed glasses.

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.

Despite her problems in socializing, Twilight is eager to connect with people on a personal level, demonstrated in her interactions with Fluttershy, when the two share their love for their pets, and Pinkie Pie, at the Crystal Prep welcoming party. Twilight is shown increasingly distressed by the apparent harm caused by her magic-sensing and storage device to the point where Sunset's eventual accusations leave her distraught.

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.

In Legend of Everfree, Twilight is depicted as more self-assured than in Friendship Games, interacting with friends and classmates more openly after transferring schools. However, she is still somewhat socially awkward, and she exhibits an intense fear of her Midnight Sparkle alter ego. Her fears do not seem to be completely unfounded, as Midnight Sparkle does appear to attempt to control her when she attempts to embrace her magic.

In Movie Magic, Twilight applies her intellect in an investigative setting by solving a missing-objects mystery on the set of the Daring Do movie. As demonstrated in the Summertime Shorts Mad Twience and Subs Rock, she can sometimes get carried away in her science experiments and pursuit of knowledge.

Abilities
Her magic manifests as telekinesis. Her power of object manipulation can be used to open locked doors, presumably by telekinetically picking the lock. It's how she frees Rainbow Dash from a supply closet in "Movie Magic".

Trivia

 * Her glasses keep slipping down her face when she's stressed out, or being pushed. She adjusts them by the corner with one hand, which is typical with Nerd Glasses, or pushing up the bridge.
 * At Crystal Prep, Twilight is often hated, bullied, or ignored by her fellow students.
 * Unlike Pony Twilight who's almost never seen wearing glasses (and only as costumes, as she doesn't need them), Human Twilight's eyesight is fairly deteriorated, as demonstrated when she's seen squinting and looking for them after bumping into Flash Sentry. We even get a P.O.V. Cam shot when Flash gives her back the glasses, showing just how blurry her vision is without them.
