well, that brings up the question, is regeneration the same as invulnerability?
I would say no. The difference between a regenerator and someone who is invulnerable is if I shoot a regenerator with a gun the bullet will pierce his flesh, damage will be inflicted, but it will heal. Shooting at someone who is invulnerable..the bullet just bounces off, no healing is required because no damage has actually been done.
Sometimes characters have both powers, but no they aren't really the same. There could be someone who regenerates so quickly it seems like no harm is being done at all.
For instance Clark from Smallville has both. Bullets bounce off him, knives shatter on his skin, etc. If you, however, do find a force powerful enough to hurt him..he can regenerate. He has been impaled through the chest and healed.
