Rarity (EG)

Rarity is one of the main characters from the My Little Pony: Equestria Girls franchise.

Rarity is a student at Canterlot High School and keytarist for the Rainbooms.

In the AWA fics, Rarity is a student at the AWA Academy.

Appearance
Rarity has a pale-white skin tone, a waist-length luscious indigo hair and has azure eyes. She wears a light-blue shirt, a purple skirt with a black belt, dark purple boots and a golden watch.

Personality
Rarity is very generous and has a keen eye for fashion. She disguises Twilight to hide her from the CHS students' ridicule, and she comes up with the idea of handing out pony ears and tails. Rarity also likes doting on the dragon-turned-puppy Spike, finding him "so adorable" and letting him sleep in her lap at the Sweet Shoppe.

Rarity's generosity and love for fashion carry over into the second and third films as well. In Rainbow Rocks, she greatly concerns herself with making a good stage impression, and in Friendship Games, she says putting effort into clothes and spending time on her friends are what she lives for.

Rarity also has a bit of a fascination with royalty, as she is excited to learn that Twilight Sparkle is a princess and has her own castle.

In the AWA fics, Rarity grew a crush on Ben Tennyson and unlike Rainbow Dash, she's a lot bolder in expressing her interest to him.

Abilities
Her magic lets her generate diamond-shaped barriers of energy. Rarity's diamond-like constructs are mainly used for defense or pushing people away, but there are hints that the power might be much more versatile, like when she creates a floating raft for Derpy, or builds a gemstone chandelier for the Crystal Gala.

Rarity is also stronger than she looks but not to Applejack's extent, but like her pony counterpart she has shown herself to be stronger than one might expect from a prim and proper fashionista. She pushes a grand piano across the school grounds  without wheels  for an unspecified distance, even if she eventually gave up and asks for help. In  Friendship Games, she swings Pinkie Pie with her leg to send her careening ahead of the competition during the rollerblading race, and at the climax, she momentarily clings to a ledge one-handed while supporting the weight of two other students.

Trivia

 * Rarity prepares a ridiculous number of outfits in  Friendship Games, ranging from motocross outfits and a hockey goalie getup to things like a cop uniform and a welder suit.
 * In the  Tell-All  book mentions that she never leaves home without nail polish (for touch-ups), a needle and thread (just in case) and a compact mirror.
 * In Twilight's nightmare in  Legend of Everfree, Rarity wants Twilight to bring a fancy party dress to a camp in the middle of the woods; when Applejack protests, she insists that if Twilight were going  to the moon  she'd have her pack a dress.


 * Rarity wears a hair dec shaped like three diamonds, mirroring her pony counterpart's cutie mark. As part of the Ambidextrous Sprite aspect of the animation, it can seem to flip from left to right and vice-versa.
 * Rarity can produce whole racks of clothes out of nowhere, or a pair of motocross outfit from behind her back.
 * It's hinted by her instant talent with the keytar, along with the Daft Punk costume she made, that she has a hidden love for electronica/techno music. She's also twice worn Beatles outfits, which given the era the universe seems to occur in would make her a fan of vintage music (which to be honest, wouldn't be a surprise). She's also a fairly decent rollerskater, and supplementary material states that her favorite subject is geometry.
