Some say it’s multiple people. Part of the myth is he’s immortal. Practically he chooses a replacement every so often so he appears he has always existed 

He’s an alchemist. Probably a vampire. Real vampires use black magic to steal energy or if he’s got a pact with a demon he could drink blood too. But that’s heavy duty magic to set up

Please reconsider.
