Suggested by Destroyer Rainbow Dash has enough speed to break the sound barrier. She knows some basic hand to hand skills and even got super powers briefly. Throw in the fact that she can fire laser blasts and I don’t see how Derpy can possibly stay in the fight. No matter how you slice it I’m afraid that Derpy has no avenue to victory here. Rainbow Dash just wins in every category relevant to the match. Rainbow Dash wins.
