BLEACH

It would probably be ichigo cause he already got rid of his hollow once

If the 2 actually fought in the bleach world not in Ichigo's head and because the hollow ichigo has the same power and strength as ichigo because they get there power from the same place it would be a great battle but hollow ichigo would win becuase he is a better fighter, that is proven from the battles in ichigo's head the only reason ichigo ever won was becuase it was his own mind all he had to do was figure out how to use his strength but in actual fighting prowess the hollow totaly kicks ichigo's ass ever time. Is that was you were asking about or do you mean ichigo verses what would be the actual hollow inside him because that is a totally different question that I would have to think a very long time about to know the answer.

I think after a very long and epic battle Ichigo would win because he has something to live for. He fights for his loved ones and has an intense drive to protect everyone around him. Hollow Ichigo has no one he is empty inside and twisted and only wants to achieve a greater power that will be his demise.

well that fight already happened and well ichigo kicked hollow ichigo's ass

I agree with michaelsway..Ichigo would win cause he already has a reason to live for and if it's not for his family it's for his friends in contrast to H(ollow)ichigo who only wants to kill..but who can blame him?he's following his honno(=instict) while Ichigo his heart... ^^

btw,have u noticed that this inner conflict is one of the biggest philosophical issues? nature vs nurture.. the way we learn to act vs the way we're been born to act lol just felt like saying that ^^ sorry if it's irrelevant to the topic ^^'
