i would love to say Luffy or ichigo since im not a fan of naruto
but after seeing Naruto go massive with 8 tails and and rip out of a giant boulder in the sky im gonna have to say him
im sure Luffy and Ichigo could do some major damage to him but the nine tails chakra will jst protect him form the outside damage instead
Luffy only uses his fist so it wont help him out since we saw the result of that before
and Ichigo only has a getsuga Tensho, speed, hollowication, cero
instantly Luffy was already removed form play due to the fact he fights barehanded so ighigo has the only real shot and i dnt think he had or currently has the power ot take something that big and powerful on
whats wors eis i currently hate naruto for being to GM'y xD
