It's interesting because some games implement a sort of "damage reduction" or threshold mechanic, to simulate how attacks below a certain amount of damage are ignored, (a la Superman and regular bullets). The issue with those, though, is that such games tend to then bake such mechanics into enemy damage numbers, so that a high level enemy, who may still be using a regular gun, now deals enough damage to overcome that threshold. I guess what I'm getting at is it isn't feasible to try and truly capture how things behave in comic books, (which, when we come right down to it, is simply writer's fiat), so things like levels, hit checks, and aggro mechanics, are acceptable breaks from "reality"...
