@MisterShin: I see, well that is something that should be taken into account.
There is the speed difference as well. Going from what I know, Wrath Asura is faster. He's at least fast enough to exit the earth's atmosphere and fly to the moon in a short period of time, so he's high up on there on the hypersonic scale at the very least.
The thing is, this not a straight up fight. The OP is not specific about how that is though. Does he mean that Wrath Asura is just trying to shrug off Kishin Asura's madness aura, and doing nothing else; that he's just standing there and not attacking Kishin Asura? If so, I'm not sure how Wrath Asura will fair. He doesn't have any notable feats of shrugging off mental manipulation.
EDIT: Still, that werewolf guy and witch lady were able to snap out of it in time. It doesn't seem too impressive.
