Is there a list of the characters in the various sets, along with an overview of the character's theme/abilities, anywhere? The card lists just have the names, and there is a little info in the product blurbs, but it would be great to be able to see all this in one place...
Downloading the character sheets would probably be your best shot. You can see everything that is on the character cards on the character sheets, be it skills, powers, card lists, flavor text or role cards.
