When I said Yama had to use a move that that would have killed himself I didnt mean Itto Kaso. But I get why you said that, what I should have said was "Yama was going to use a move that would have ended in his own death.".
@UltimateHero0406: We have never seen Aizens bankai so saying that Yamajis Bankai release makes his stats better when we have never seen Aizens full power makes no sense. Aizen was already known to be stronger than all Captains hence why even before he started to access the Hyogyaku he wiped the floor with them. Yamamato was goin to use Jigoku to kill Aizen, Himself and everyone else within range because he knew it was the only way to ensure his death. And as I said before the data book written by Tite himself not only stated that Yamaji and Aizen were equal stat wise but that Aizen was known by every shinigami to have mastered every skill possible. Aizen was the yin to Yamas yang, the brain to his brawn before he evolved.
Kennys main problem here is Hulk. Between them the fight could go any way. Kennpachi has shown enough strength, speed, and endurance to fight Hulk especially if he takes off his eye-patch. The only thing that is sure in this fight is that Hulk will be extremely pissed and Kenny will be the happiest he has ever been.
This is one of the better Anime vs Comic battles in my opinion.
Aizens main problems here is going to be Strange and Thor since they are the only ones here who know how to deal with magical threats. Everyone else serve strategic pawns. If they can find a way to stop Aizens evolutions they can win if not Aizen wins after a good fight. I would say Aizen wins 7/10
