1) Not much of a verse battle when he is fighting a total of 8 guys.
2) Is this supposed to be a gauntlet? If so, why the hell is Zabuza placed at the end when he is allegedly weaker than all the others? (Barring Hidan because I think Zabuza could take him but whatever).
3) When did Naruto get a character named Aizen? lol
4) Aizen stomps. With not too much difficulty. The Aizen he faces will see a team up to be more beneficial that a fight.
