I'm not a fan of Captain shota, but if you observed closely, how many battles did he lose? One. The only battle against Aizen, which is like, the ultimate villain. The battle against Gin. Gin got fucked, in the manga, he didnt even battle, Hitsugaya performed his shikai and froze his hand, the Ichimaru used his blade-erection an ran off like a dirty dog. In the shitty bounto arc, that dude with the headphones was hopeless against shota-boy. Shawlong. That dude got fucking one-hitted after Hitsugayas limit release. And he was badly, I mean badly injured, but he still managed to rape him in a single blow. Then Luppi. Everyone claims that the captain got owned. Water was surrounding him, you really think you can own someone when he has a hold of an infinite bankai? I think thats all the battles, since im not really following the anime, just read the manga sometimes.
