Bleach 301

[anime nomad]

Zaraki is the only one to have ever made Captain level without bankai.
......Where is everyone elses bankai? None of the vaizards used it, Urahara isn't using it, Ishin isn't using it...

Aizen is still fighting @ Shikai level, by Shonen Rules - the first one to power up losses the battle , i.e. its always the bad guy that uses his power up first, then the hero comes along with his super power up to blow him away. besides its bad form to fight a Shikai with bankai - makes you look weak.

Proof that Gins Eyes are not just folds of skin in his head.
