I'll go with Aokiji after a long hard fight
" @Ketch: he can win even without bankai using kido "Hitsugaya has shown no real skill in Kido. I cant even remember the last time he used it. He prefers to use his zanpakuto. Even if he did use Kido we dont know at what level he is at. Even so Aokiji can become ice on reflex. Any damage done to Aokiji will prove useless as he would instantly reform, and he could reform around Hitsugaya himself and turn him into ice and shatter him before he realizes whats happaening.
" http://bleach.wikia.com/wiki/T%C5%8Dshir%C5%8D_Hitsugayaright so far that thing have been wrong , hitsugaya AFAIK never uses kido
Kidō Expert: Hitsugaya is highly proficient in Kidō and is capable of performing high-level Kidō spells without the incantation. "
" @cfatalis: look even without kido he wins cause his bankai can freeze everything even admiral frosty "@battleheiz said:
" @cfatalis: so what he still can be freezed and don't forget that it's ice dragon vs ice fruit "Are you serious? How do you freeze ice? Better yet, how do you freeze someone that can become ice? Make that make some sense, seriously.
