I don't think campy is inherently wrong. And I wasn't really proposing to get rid of the campiness of forgotten characters, just the bits that would be considered lame and wouldn't work in modern stories. Morrison loves creating campy stuff, however, he adds really cool aspects to make some contrast. For instance, I love Egghead, but the egg-puns gotta go. I wouldn't change the Turtle Man, he doesn't seem campy of forgotten to me, he seems to have evolved with the times.
I originally said the rere are four aspects: appearance, powersr/abilities, m.o., personality, there's no need to change what is working fine.
btw, I agree Prometheus is Wrath. Furthermore: Wrath is Killer Moth.
