Suggested by iKnowledge Reverse Flash and Ardyn Izunia are both speedsters whose abilities are far beyond that of mere mortals. Both know how to defeat other speedsters as well but I’d have to give this one to Ardyn. Speed to the point of teleportation is always really handy and the guy has energy blasts, magic, and a whole lot of other abilities as well. Reverse Flash doesn’t have any of that and that’s why he would end up getting left behind here. There’s just not a whole lot that he could do to stop Ardyn here. Ardyn Izunia wins.
