Yeah, not entirely sure what to describe Mason as. He's undead however he's in full control, eat food, have sex, can get high, needs warmth and nutrition but can't die. He recovers fast from fatal injuries. Not sure if he could recover from complete destruction tho. His only powers are to "save" souls which is used to spare them from the pain of dying. He can forcefully remove the soul of someone, only leaving a zombie husk behind. He can see dead people and seems to be able to sense other Grim Reapers. But he's not allowed to kill. He can but it has dire consequences. He can also see what I'd describe as evil spirits which causes death, gravelings.

I don't know if he could sense if something is off with Theo tho.

Thanks for your answers.
