What degrees of the supernatural are acceptable, and how much leeway in rewriting backstories are we granted?

I'll also add onto what Andy said. When we conceptualized this game, we took into account supernatural aspects as certain street level characters are mystical in nature, and we wanted to be able to accommodate that. So long as the concept is inherently street level, as in dealing with city-wide concerns and not reality-ending threats, and the character can feasibly interact with the gang war storyline the narrative will follow without easily solving every issue through deus ex [i]magica[/i], it should be within the scope of the game.

Basically, there's about two dozen supernatural crime fighters in Marvel's NYC that I can name off the top of my head, all of whom are street level, so as long as the character is roughly comparable to them I see no issues.
