Suggested by Destroyer Norman Bates has a gun, but that’s really all he’s got going for him. Beyond that he is just an ordinary guy so Rainbow Dash will have no trouble dealing with him. She has super speed which is incredibly handy in all kinds of situations. She can dodge every shot and just barrel into him. A tackle at that speed will certainly leave a mark and Norman will have no way to recover from such a shot. Rainbow Dash wins.
