Rainbow Dash is a female Pegasus pony and one of the main characters in My Little Pony Friendship is Magic. She maintains the weather and clears the skies in Ponyville. As a huge fan of the Wonderbolts, she becomes a reservist member of the elite flying group in Testing Testing 1, 2, 3 and a full member inNewbie Dash. In Sonic Rainboom, Rarity and Princess Celestia both declare that she is the best flier in all of Equestria. Rainbow Dash has a pet tortoise named Tank, whom she chooses out of Fluttershy’s offered animals in the episode May the Best Pet Win! She represents the element of loyalty.
Rainbow Dash has a flashback in Games Ponies Play to an event in Cloudsdale where she is a young filly without a cutie mark. She is accompanied by Rainbow Blaze, a stallion who has similar rainbow-colored mane and tail as her and a similar blue coat, with a rainbow-colored cutie mark. They are standing in the crowd listening to an announcement about where the Equestria Games will take place. When Dash hears that the Games won’t take place in Cloudsdale, she cries out in disappointment.
This disappointment is somewhat assuaged later when young Rainbow was selected to carry Cloudsdale’s flag in the Equestria Games opening ceremony. She boastfully claims in Flight to the Finish that she “did tricks with that flag the likes of which nopony saw before and nopony’s seen since!”
