Café de Nuit

It manages to develop an alternate personality due to the new experiences and decides every other Toben is a copy and fraud; it alone is Toben the Many. But of course, it needs allies if it is to destroy the rest…

Ooh, this may be my favorite idea yet. Inspired by Hugh of Borg perhaps?

No, an entirely independant idea.
Well, probably owes a little to Multiple Man from X-Factor. He and his doubles never saw eye-to-eye all the time. And I'm also reminded of every "copied" or "cloned" story in sci-fi where a few divergent experiences alter people.
The only reason Toben plays nicely with himself is they all have the exact same personality, one variant and they're suddenly competition.
