She is the daughter of Sky Stinger and Vapor Trail :3
Being the oldest out of her sisters Vestigium Trail and Skye Styles, she felt like the responsibility was on her to be encouraging to her siblings and to make a good name for her family with the Wonderbolts. This caused her to train herself to tip-top shape, and also resulted in some overconfidence issues, especially involving her leadership skills (Which tbf, she did have the stats to prove it XD)
After Vestigium’s accident that resulted in her getting her leg and wing crippled and being unable to move right anymore, she kept giving herself self-doubt about her abilities as a leader, since she keeps blaming herself for not being there for her (even though her sister knows that it is not her fault). Because of this, she has taken a less active role in leadership, and made her more of a follower then a leader.
She is still a talented flyer and is a very nice girl to hang around with, but now she has trouble trying to take charge of things becuase she worries she is gonna screw up and something bad will happen.
