I'd be interested although am curious: what's the available roster like? Are we sticking to certain universes or is anything up for grabs?

Besides Marvel?

Or is this a question of: "If I do Spider-Man can I be Ultimate, or do I have to be regular?" The answer to that would be...I don't care. Up to you.

Available roster is:

Tony Stark is taken.

Jean Grey is taken.

And that's it so far.
