In the stories i write about the Wonderbolts on Fimfiction i messed with their heights/sizes. So Soarin is a really big dude and Spitfire is one buff mare.Personalities are taken from my work as well, With Fleetfoot being shameless, Spitfire being overly serious, Dash being overly brash, and Soarin being a goofball that easily plays into the personalities of the other three.
