Don't you remember Aizen is planning to destroy KT town to make the King's key?Maybe he wants to kill the SS King and take the throne for himself.He did mention that he wanted to be at the top and that no one has accomplished that feat at the sokyouku hill.This might imply that the SS King might have died and that the throne was empty.

no, i don't think so. ichigo is not the reincarnation. he IS the king. nor he is the key because, well, since he IS the king himself..........

anyway could someone pls tell kubosen not to drag on the huecomundo story, let orihime outta the place and LET"S HAVE A FIGHT with aizen!!!!!!!!!!

thats just speculation...u said it as though as if its a fact
