I'll start tinkering on a character.

You okay with a mutant (meta) who is neither a villain nor a hero? Someone on the start of an anti-hero path, as a gang-member and a bit of a hoodlum? A character with powers but no actual, formal experience. 

In summary - an inexperienced mutant living in a bad neighborhood, and does some bad shit for reasons they believe are right.

Or would you rather we play more battle-hardened and experienced soldier-type characters?
