You know, the problem with OP characters that are not main characters, is that somehow you know there will be a moment when somebody will curbstomp them. If Kenpachi achieves bankai, I bet Kubo will take some weird villain out of his dark mind (or simply have Aizen back into action) to curbstomp Kenpachi and scare the audience, and then have Ichigo solve everything with his main character-kai.
