Also we still need to see Kenpachi fight someone with a special ability. Even with his ridiculously over-stacked amount of brute strength i still don't see him beating someone like Gin, Mayuri, Shinji, Or Starrk without kubo choreographing the fight in his favor. The only reason he defeated Kaname Tosen was because, for whatever reason, he chose not to mortally wound kenpachi or even use kido.
