We have no idea what Roger can do.
Batman doesn't need 2 years of prep or an army to dispose of Naruto. Batman wins by himself with no difficulty.
@SpeedForceSpider: This is non Edo Madara. He can't fight with the same recklessness. We have yet to see Mihawk go all out and from what we have seen, the guy is damn scary. I think he can take round 1. Round 2 if Madara manages to get perfect Susanoo off he should win if not then he would probably get sliced to bits.
The Justice League would win. Only threat on the Avengers side is Thor. The Hulk really serves no purpose here he is too slow. Z Fighters have no threats on their side worth mentioning(sorry DBZ fans Goku won't save you here). JLA should win fairly easily.
