Uh... Okay, that defies physics and all knowledge of biology and pretty much renders him undead, but okay, if that's what you really want. I kinda think that's a little OP for his regenerative abilities to be that advanced, but I'm not GM. It's up to Spawnling and Viridian, I'm just saying that as main villain, you may want to tone it down just a smidge, you know, so everybody gets a chance to beat up the monsters and get beaten up by monsters.
