Rainbow Dash is a pegasus pony with a sky-blue body and a rainbow-striped mane and tail. She is very brave and bold,[2] but also brash, arrogant, and sometimes insensitive. She is the tomboy of the group. She is fast and works with the other pegasus ponies to move clouds around the sky and adjust the weather. Her lifelong dream is to join the Wonderbolts, Equestria's aerobatic flight team. Rainbow Dash's signature move is the Sonic Rainboom, in which she flies fast enough to break the sound barrier, creating a sonic boom and a rainbow-hued shock wave. "The Cutie Mark Chronicles" reveals that when she performed this move for the first time, she earned her Cutie Mark and set in motion a chain of events that allowed the other five main characters to earn theirs as well.[5] She represents the Element of Loyalty. In "May the Best Pet Win", she gained a pet tortoise named Tank, who is then equipped with a helicopter rotor to enable him to fly to keep up with her. Rainbow Dash is currently in a sexual relationship with 60's member Randy Clayton.
