As far as Character Sheets go, your guess is as good as mine. Expect the standard stuff and a little beyond that, I'm looking for well balanced characters that are flawed in more than one way. By caps if you mean like caps on power and abilities and stuff, I'm not sure of that either. Thor/Hulk/Jean Grey level characters are out of the question, most likely we'll be flirting Luke Cage/Spider-Man/Black Panther level heroes who are decent in their own right but won't be demolishing waves of enemies at a time. "B Class" heroes might be a good way to put it. When it comes to Anti-heroes I'm pretty sure that's gonna be the norm. Since no heroes have existed before us I'd find it strange if there were many die hard heroes like Captain America or Superman types who aim for good through and through, our characters will routinely struggle with being heroic and selfless since it won't be a natural thing in our world. I'm not sure how much that helps but that's just what I'm thinking at this moment.
