What, just because an attack annihilates half a continent, you think it's overpowered?
I think they could still work.
Judgment: The angel/knight drops down from the heavens, aims his lion-cannon down, charges it, and it fires an energy bolt down the center of the stage. The beam hits the ground and makes a spherical explosion of blue energy, and then a shockwave emanates from either side. The appearance and charging sequence would be more than enough time to run away, and then players far enough away could jump over the shockwave,
or perhaps shield from it. It doesn't seem any more undodgeable than Mario's. They could also modify Judgment somewhat, too, so it wouldn't necessarily behave exactly as it does in the games.
