@Hirako_Fan: It depends when he is attacking. This is a pretty bad thread he didn't specify anything what so ever so it is hard to judge who would win.
If goku gets to IT it's game over for flash. He just has to It off the planet then blow it up. On ground he would die unless he some how lived long enough to notice the hits then got a milisecond response to do one hit on flash because that should be more then enough to kill him.
Isn't death kind of irreverent to goku since he dies all the time anyway and was dead at the end of the buu saga.
Guy has tons of speed to his advantage where akuma has a bit more power this is a pretty good fight but i think guy would win if he was willing to go all out on akuma.
Sonics them song even says faster then the speed of sound so i think speed of sound beats speed but it's not just a race right so then sonic breaks the car in one hit then beats the crap out of speed.
Ok so Atem with blood lust on and every Millenium item and his ability's from Egyptian arc vs anyone from the jump universe (Any character from the jump universe the the universe at the same time).
Atem and your character get an hour prep time. They are fighting in a deserted area.
