I wouldn't go that far. Anyway fodder characters in OP would be killed. Take Garp for example, could you see Hiei or Kurama easily pwn this insanely strong old bastard?
I wish we had seen more of Garp during the war.
He has 2 feats: The colossal iron ball toss and punching Marco in phoenix form. One is insanely ridiculous, the other not much of a showing of his hyped power. Same with Sengoku. He has an interesting DF but we only saw him fight with BB for a shot while, but he was impressive though.
I would love to him fight Jozu, both are ridiculous in terms of raw strength and a fight between the two would cause a few mountains to be relocated.
