Its interesting, ofc the whole "Monster can't hurt a human thing" ext... doesn't mean anything when superheroes can more or less take out armies by themselves at times. When the balance of power is so skewed, laws are more of a suggestion and not an actual law, because they're incredibly hard to enforce.

I could give it a shot. Portals or Regeneration, which power set?

And only new age batman doesn't kill. The 60s batman killed all the time and laughed about it. Oh, the good ol' Adam West days...
