Re: I' m in a philosophical mood tonight.
MMmm, that is a tough one..
Crimson Aura - well, considering she's half demon herself, she could easiely become a bad guy if there weren't any to fight! I think she'd have a hard time accepting a "Utopian" world because somewhere in the back of her mind she would suspect it was just someone way of controlling/enslaving everyone (ala "Brave New World")
Starry Knight - she had the chance to be in on the ground floor of the creation of a new nation, and knows that taking care of everyone isn't easy. But since she's also a singer/exotic dancer, she'd love to spend her time singing, dancing and spending time with her recently reunited with husband.
Blaze - she didn't start out to fight crime, just to gain fame and fortune for herself. Her morality lead her to oppose villians, but in their absence, she'd still be out for herself.
Mmm, it would seem that a character who was in the game just to fight crime would probably have it rough in a perfect world. Most of my heros were such by necessity, not choice (probably some sort of reflection of my own physche) and would continue to have things to do if all the villians in the world were gone.
