...except Kenpachi managed to EFFORTLESSLY kill 3 Sternritter with only his Shikai, with Yamamoto being the ONLY other Shinigami thus far to replicate such a feat, and with only one Ritter at that. And this was before his apparently massive power increase from fighting and being repeatedly killed/healed by Unohana. Suffice to say, he;s already proven he doesn't need Bankai to kick ass.
