A Different Kind of Battle

etsu. He couldn't supress all of Zangetsu's power and Ichigo has been using that fragment part which the quincy part couldn't supress. And you're right about the rest.

became ichigo's main source of power. After his talk with the old man Ichigo is seen using two swords then; one is large and represents his shinigami powers, one is short and comes from his quincy powers, stating that both of them are zangetsu, not just one. I think that should be it. Don't really understand it that well myself.. Or in short: Yes, for those who don't read the manga this guy is known as hollow ichigo, but those who read the manga know that there's more to it and he's in fact zangetsu. Hm, if somebody requests "Zangetsu" I'd say go with the old man. I think most of the fans will refer to this fellow here to hollow ichigo anyway since it's too bothersome to write "zangetsu (hollow/shinigami)". Not to mention that you're spoiling some fans and have to endure the questions following this again and again... Or you could draw both of them when somebody wants zangetsu, double-teaming...ah, well, nevermind. ^^
