"Kubo mentioned Kenpachi was one of the three strongest captains. Right behind Unohana (2nd strongest) and Yamamoto (strongest). "

This is false. I don't know where you are getting this but the three strongest captains are Yama, Unohana, Shunsui. Not sure where you are getting your info from but its wrong.

Also, Kenpachi has no ability that allows him to become as strong as his opponent. That is pure fan fiction. We just have never seen him face an opponent that really challenged him aside from Ichigo and maybe Nnoitra.
