(Here Comes the) Supernatural Anaesthetist
Genesis
Exhausted by all this conjecture, our hero gets the chance in a lifetime to meet his hero: Death. Death is wearing a light disguise, he made the outfit himself. He calls it the "Supernatural Anaesthetist." Death likes meeting people and wants to travel. Death approaches Rael with his special canister, releases a puff, and appears to walk away content into the wall.
