Simple plot really. Keep this fair, no uber-powers and definately no more than three. There's obviously no guns in Heaven and Hell, so it's swords and shields amd all those shenanigans in here.
I don't want a bio, just a good introduction (appearence, powers, weapons, etc.).

--------------------------------

Heaven and Hell, they've lived in peace forever - up till now. Hell has opened a crack in the land and is letting its elite troops, Hell's Demons, into the World. To counter this Heaven have sent in their elite's, Heaven's Heros, as well. Now, Heaven and Hell battle it out on the streets of New York, the rooftops as well.
