Hrrmm... Genjutsu wouldn't work but Amaterasu "mite".
Dang it. I forgot about the hotter than the sun hell flames, that can't incinerate trees for some odd reason.
Well, I guess the Hulk, even with his ridiculously broken regen would be powerless when confronted with such epic flames, that can't even burn shirts or armor. I guess the Hulk should stick with small game such as punching and destroying asteroids bigger than the planet earth and stuff.
My apologies, what was I thinking ????
