Hmm...how about a character for less of a man? I was thinking maybe someone who can alter people's memories, but as a price, he loses some of his own memories. Would play a really cool anti-hero role in the story.
Hmm...how about he's an artificial person? Created by the government to see if they can distribute names by themselves, but they fail in that the characters powers come at a cost greater than usual. So, he's traveling the world to see what he can do to get rid of his name entirely, rather than change it like the main cast.
