Of course, the problem is that King Hassan can literally erase you from existence. Those he kills stay dead.
Though, in a game, dunno if that would be put in lol.
If it were an actual game mechanic it would be that when you die it deletes your save. Some games do this.
But otherwise I'd rather this not become a crossover powerlevel debate. Let's just leave it that whoever wins I don't care as long as an epic battle ensues.
