I like Kenpachi. He's my favorite Bleach character, by far.
I would have really really for realz liked to see Aizen killed and Gin take over. That makes much more sense as you don't have to "retcon" 300+chapters to make the story fit right. (Gin had Aizen reveal his 'weakness' when he was still a growing kid...stupid that he didn't get evidence and turn Aizen in at that point and then ask to execute Aizen, himself. Stupid stupid stupid.)
Now, the story has to be retconned and that might not even happen! (He could just leave it as a major plot hole.)
With the way I wanted to write it, Gin would still get to do the same things he did except, in my version, he still maintains his sanity and dignity. It makes more sense that Gin would want to kill Aizen, right at that point, then at any other: when they finally got to Kakura Town and Aizen revealed the last line about creating the kings key, Gin kills Aizen and creates the key for himself.
Takes the crystal.
R@pe stomps the king and squad 0...or at least tries to.
