Hey I have a theory and I wanted to know if anyone agress with me. I think Isshin Kurosaki could be the former Kenpachi. I dont know if this could be possible acording to the time line, but it would make sense considering he used to be a captain and his son having such high spiritual energy and growing stronger so quickly and the fact that Ichigo relise on power and isnt so good at kido. When they series went back to the past they never show the current Kenpachi they only talk about him and says he does what he wants pretty much. I would love for someone to figure out if its possible im too lazy and WOW it would be cool if he was! The former Kenpachi was killed by Zaraki, but can it still be possible?
