time i got up there after him,he'd be on his damn throne,an the lord god sits on his seat of eternity,ain't a gun in creation can scratch his damn hide.not even one says colt on the barrel.preacher#60.so he's not omnipotent.he was hit in the chest by an atomic bomb that killed 8,000 people and didn't get a scratch.just said not enough gun.all this being said and him being death's angel and killing both god and the devil really shows his power.why did jesse custer stop the saint of killers using the word of god when god himself could not?how did cassidy survive being shot when no one else has??is far as his invulnerability is concerned,going against galactus would be a lot worse than geeting hit with a nuke.killer of saints takes it i think but again their are some inconsistencies that make it hard to judge his power level
