OK, here goes:
Finesse: Unofficial second in command - instinctively takes command if Chronal isn't there, and the others accept and expect this. Witty, observant, quick thinking. Probably has concealed issues about her super-power, which is a partial reflection of her appreciation of her friends - she's much better at using their powers than anyone else's, so when they're not around she feels it.
SHIFT: I think a sense of calm should be relevant to her. She can fight, and has the potential for anger etc. but close to her nature is inner peace. Yeah, and she probably loves trivia.
We're a group of mates, so I think it's worth making sure we keep up making it clear that these guys really get on. That's definitely already in there, just thought I'd mention it's good!
NARRATOR: Yeah, I was WELL proud of that one! It's really cool you've made him an unimaginative loser, too. It means we can have fun with him being an idiot, and if we get bored but want to keep the character we can always make him cool and dangerous.
I think The Pit should look like a Centre Parcs Villa with more rooms and secret passageways etc. added - cool to have a basic structure we all know and love!
OK, I'll get cracking on Issue the Third! :-)
