[@Dedonus] So are alternate versions of characters acceptable? Like Kid Pool or Ultimate Deadpool?

Anyways, do you have any ideas to make an original origin for Gambit? Because that sir, would be very helpful.

As long as it fits the setting of this game, then you can use alternate versions of characters that don't have a character sheet.  So, Ultimate Deadpool would be out because we already have a Deadpool.
