Rainbow Dash (EG)

"Crystal Prep students are super athletic, super smart, and super motivated. But there's one thing they aren't. They aren't Wondercolts!"

- Rainbow Dash (EG) Rainbow Dash's human counterpart appears in the My Little Pony Equestria Girls film series. She is a student at Canterlot High School and electric guitarist/lead vocalist for the Rainbooms.

Personality
Like her pony counterpart, Rainbow Dash is very athletic and competitive. She is the captain of every sports team at Canterlot High School, and she effortlessly overtakes Twilight Sparkle in a game of one-on-one. She is also somewhat self-centered, often speaking—and sometimes singing—about her own awesomeness.

In the second film, Rainbow is conceited to the point of frequently calling the Rainbooms her band. However, she humbly steps aside for Twilight to take over lead vocals, and she lets Sunset Shimmer join the band by the end.

Rainbow Dash's strongest trait is her loyalty. She eagerly teams up with Twilight to beat Sunset in the first film, and in the third film, she gives up a victory in the Friendship Games to save Sunset's life. She also able to inspire motivation in others as demonstrated in Friendship Games ' CHS Rally Song.

My Little Pony Equestria Girls
In My Little Pony Equestria Girls, Rainbow Dash is Canterlot High School's resident jock, being captain of all the school's sports teams. She is first mentioned to have had a falling out with Applejack, but after Applejack discovers they were driven apart by the machinations of Sunset Shimmer, the girls reconcile at Twilight Sparkle's urging.

Rainbow tells Twilight that she will only help her become Princess of the Fall Formal if she beats her in a soccer match, with the first to make five goals winning. Rainbow easily wins, but she helps Twilight anyway, telling her that she was testing her determination.

When Twilight invokes the power of the element of magic, Rainbow briefly channels the element of loyalty and gains pony-like attributes. After Sunset Shimmer is defeated, Rainbow flies around at the Fall Formal, picking up Scootaloo and giving her a ride. Her wings and pony ears vanish when the portal to Equestria closes after Twilight's departure.

Equestria Girls: Rainbow Rocks
Rainbow Dash reappears in Rainbow Rocks and its tie-in animated shorts, where she plays lead guitar in her friends' band, the Rainbooms. She first appears helping her friends make a poster for the CHS Musical Showcase. In the Rainbooms, she is initially the lead vocalist as well as the guitarist and songwriter. When Twilight returns to the human world, she takes over as lead vocalist.

Throughout the film, Rainbow Dash shows moments of egotism, taking credit for the formation of the Rainbooms, frequently stating that it's her band since she's the leader, judging her friends' performances, and being reluctant to play songs that Fluttershy had written. After Sunset Shimmer's speech, she finally sees the error of her ways and acknowledges that it is "our band"

Equestria Girls: Friendship Games
Rainbow Dash appears again in Friendship Games, competing in the games against Crystal Prep Academy as part of Canterlot High's Wondercolts team. Rainbow helps motivate her classmates to win the games with a spirited song, ponying up at the end.

She participates in the Academic Decathlon, where she passes the chemistry, baking, and carpentry contests, but drops out of the spelling bee after misspelling "hippopotamus". She and Sunset Shimmer are paired up in the motocross portion of the Tri-Cross Relay. When the human world's Twilight Sparkle accidentally summons carnivorous plants from Equestria in the middle of the race, Dash turns around to save Sunset's life in an act of loyalty. She ponies up a second time and wards off the plants, allowing Sunset to win the relay, before getting her magic absorbed by Twilight's amulet. She later regains her magic to empower Sunset and return Twilight to normal after she is transformed into Midnight Sparkle.
