She is the daughter of Fleetfoot and Spitfire. :3
She is a punk girl, and she is a very skilled flyer. Although despite being a good flyer, she has gotten a lot of controversy from the press, due to her carefree and risk taker attitude, which also puts her at odds with her parents (They do love her, but they do wish that she would take more care of herself, not because it makes the Wonderbolts look bad, but because they are genuinely worried for her health and safety)
After some time in the Wonderbolts, she decided to leave, and join Lightning Dust’s team, the Washouts, which is further putting a strain on her relationship with her mothers.
They do love eachother, but their lifestyle choices have them at odds.
Despite her punk attitude, she is still a caring pony, and she is still willing to stand up for her friends.
