*Rainbow Dash is a female human, a student from Canterlot High School, and electric guitarist/lead vocalist for the Rainbooms. She is one of the main characters in My Little Pony Equestria Girls. She represents the element of loyalty.

She is voiced by Ashleigh Ball, who also voices Applejack in the same franchise.

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.

Rainbow Dash is a human girl with sky-blue skin, rainbow-colored hair, and magenta eyes. She has red, yellow and blue wristbands on her wrists, and since The Legend of Everfree, she wears a blue necklace with a neon blue geode pendant and her pony counterpart's cutie mark on it around her neck. She previously wore a blue short-sleeved sweatshirt over a white shirt with a black collar and her pony counterpart's cutie mark on it, a pink and white skirt with tight-fitting black bike shorts underneath, socks of the same color as her wristbands, and blue and white knee-high boots.

In the Digital Series, she currently wears a blue hoodie-like jacket with yellow lines on either side of the sleeves, a new white shirt with a blue line on the bottom and her same pony counterpart's cutie mark on it, darker blue (or sometimes black) sweatpants with rainbow-colored lightning bolts, and blue, red, white and yellow sneakers.

In Legend of Everfree, she wears a white and red short-sleeved summer camp shirt, blue ¾ length cargo pants, white socks with red, yellow and blue stripes the same as her wristbands, and red high-top sneakers with white soles and a yellow lightning bolt on the sides near the heel.

In summertime shorts and Forgotten Friendship when swimming, she has a pink hat with a cloud and sun on it, and wears a black sleeveless shirt with a yellow, green and pink lightning pattern which reveals her midriff, pink and black swim shorts, and golden-yellow and pink sandals.

In Spring Breakdown, her hair is tied into a ponytail, and she wears a red, yellow, green and blue horizontal-striped tank top with a tied knot on the front which also reveals her midriff, newport blue running trousers, a magenta cap with orange, yellow, and green horizontal strips and a cloud on the front, a blue wristband with a sky-blue stripe in the middle and the geode pendant from her necklace on it, and vanadyl blue, open-toed, flat-mesh sandals with yellow elastic slingback ankle straps and a pair of red decorative wings on top.

In Sunset's Backstage Pass, she wears…

In Holidays Unwrapped, she wears…

When doing yoga with Sunset, she wears a purple sleeveless shirt with tied-knot on the bottom, cyan calf-length pants with purple zigzag and dots on the bottom pant legs, and she goes barefoot.

When in her Crystal Guardian formation, her hair tied back in a ponytail with a cloud-lightning bolt hairpin, has bright blue crystalline wings, and she wears a glittery red dress with a blue diagonal sash down the front, translucent yellow lightning bolts affixed to the open skirt front, knee-length blue tights, small gold shoulder pads, gold sneakers with wings, and orange wrist guards.

When in her Friendship Power formation, her hair is tied into a ponytail, and her wristbands become wrist guards.*
