Which is why his only losses are against Aizen amirite?!
He has not fought anyone but an unserious Gin, random Arrancar, and Harribel, whom he admittedly surprised with some random attack we never saw before, but before that Harriel would have killed him were it not for his amazing Water Clone that he stole from Zabuza, and she then was fending off him and those two Vizard. He then beat up his childhood friend and was pwned by Aizen.
