from captain america and the avengers for the NES. his powers would include throwing his shield of course, but also floating on lava by using his shield like a makeshift boat, same as in the NES game! he would also be able to thrust downward with his shield to goomba stuff (same as in the game) and he would be able to charge forwards with his shield by double tapping forward key. maybe he could also be able to hang from the edges of blocks, kind of like RYU but only at the top of the corner and not climb up or down, hanging was a very important part of that game. and of course he would be able to use his shield to make projectiles bounce! actually i would be happier to see him in super retro squad as something else with the same abilities, but he could also fit in here.
