Wasn't this topic an arguement that arose on a seperate thread?
Anyway, what you guys don't get is that by definition, no speedster can beat the Flash. Not XLR8, not Quicksilver, not anyone.
Why? because of the speedforce. The speedforce is an energy field created by the kinetic energy of everything around us. This is what DC speedsters tap into to get their superspeed. So what I'm saying is that the more XLR8 moves, he only makes flash faster, so if he decides to go a the fastest speed he ever has, then he would only make the speedforce stronger, and Flash would become faster.
Round 1 has a chance to go either way because supes will hold back. If Sasuke is allowed to do a few underhanded things without Naruto being all "moral high road-never-hit-an-opponent-when-they're-down-bonds" crap, they might have a chance.
Round 2...not so much. Superman will roast them. then eat em for breakfast. then rape their wives and daughters...lol
In hindsight to the events of JL: Darkseid War, we will soon learn that there are three Jokers (one for each of his three different backstories), and all the different Joker backstories will become equally valid.
