Spawn who had beaten Kratos and the only opponent seen so far where even Superman would be scared facing him.
We're talking can completely regenerate his body from any wounds, cannot die save for heavenly weapons which Superman does not posses, can stop time and move time as he pleases, has beaten dark gods that have wrecked the armies of heaven and hell before, can summon anything his imagination can come up, can teleport frag superman's body, pre-cog, Ftl speeds, possesses magic and can control elements at his will, and had a universal form where he trolled God and satan and recreated the universe in his own image and last I checked, he may still be a universal being.
Yes but they're my kind of stupid.
