RainbowDash is a pony character from the show My Little Pony. In the new generation (My Little Pony: Friendship Is Magic) RainbowDash has a rainbow mane and tail, blue body, blue wings, pink/magenta eyes and has a rainbow thunderbolt coming out of a cloud as a cutie mark. (Cutie Mark-A mark on the pony's 'flank' when they find a special talent they have. Usually gotten at a young age) RainbowDash is famous for being fast, braggy-ish, adventurous. And for her catch fraise "It needs to be about 20% cooler". RainbowDash and her friends are so famous that they take parts in Fanfics such as "Cupcakes", "Rainbow Factory", and "My Little Dashie" (I suggest you don't read Cupcakes or Rainbow Factory, it's a bit gory.)
