For a Supers game, I've been wanting to play a dragon - just start the game with a chunk of the downtown business district for my hoard, run it with enlightened self-interest (high wages, free healthcare, etc), and go after any supervillains that might threaten my modern "hoard" (which might include the people!)

The idea is that he'd be trying to transition himself from an avatar of fear and flame into something humanity might celebrate, or even venerate - after all, he's seen that humanity tends to wipe out things that terrify it!
