LOL, just a thought, but Yama's bankai has the power to resurrect the souls of anybody it killed. Well, Juha Bach stole that power then clearly killed him with it, so...........Zombie Yama FTW!!!!!
Honest to god people, it's gonna happen. Bach will show back up again summon up Yama right in front of the Gotei 13 and spout some arrogant bullshit like "I'm just gonna leave THIS
right here :P". Then while all the shinigami are shitting their pants at the thought of facing there former megaboss, he calmly walks off to go fight the 0 squad.
