History
Rainbow Dash was the first in her class to get her cutie mark. She tells the Cutie Mark Crusaders in The Cutie Mark Chronicles the story of how she got her cutie mark. Her story is set in summer flight camp, where she defends Fluttershy from a pair of bullies, who refer to Rainbow Dash as "Rainbow Crash". Hoops, one of the bullies already has their cutie marks, where Dash and Fluttershy do not. Dash challenges the two bullies to a flying Pegasus race, and in the ensuing contest she discovers her passion for speed and for "winning", in her words. Going through the race course, she performs her very first sonic rainboom, not only gaining her own cutie mark, but also inadvertently setting in motion the events that would cause Fluttershy and her future Ponyville friends to gain their own cutie marks.
