Ben10

not voted I had forgot this, but his clones don't just disappear after a few hits like a Naruto. I'm not sure how long they stay but I know that a simple blast won't just get rid of them.

Vegeta (DB) & Goku (DB) Dont know if you know this but goku has been trained to get out of illusions so that wouldn't effect him.

Ben 10 (Ben 10) In going for Ben because of alien x. Some people would say that goku could kill him before he could do that but he has tooken an explosion the size of existence to the face in human form. So I think he would have the chance to turn. But I also think it would be a tie and they would just look at each other and say draw because they know they wouldn't be able to beat one another. But my vote is for Ben.
