I'm currently modifying Iceman's powerset for Cyclops. The only things I'm running into trouble with are getting all the power effects chosen, since it's a total pain going one by one trying to figure out what works where. Everytime I get one power looking good, another stops working right. I have a _4_combat file made as well, though it has all the usual XML2 problems (no light/heavy attack animations), but the powers look correct from an animation standpoint. It's just a matter of renaming and editing the powers, changing the icons, then tweaking the power effects so that they look how they should. (If anyone wants to help with that last one, i.e. coming up with a cyclops appropriate effects set, you'll have my gratitude...)
