Kenpachi vs Killer Bee
Kenpachi has his eyepatch off and is using both hands while K.B. is in his full 8-tails form, which is (of course) much bigger and (probably) more powerful than Yammy and also isn't a complete piece of crap like him.
who wins this fight?
p.s: what I said earlier about K.B. probably being more powerful than Yammy, I just now realized something: K.B. actually is imo more powerful than Yammy will ever be regardless of what he does.
