Which made me belive Satan was more a title than a real character.
But then, there is the case of Loki, whose first apperances (Venus Vol 1), depicted him as Satan. He is recognized by not only his demon servants as such but also by the Olympians that refered to him indistinctly as Loki, Lucifer and Satan.
As far as I know that is the most widespread recognition someone called Satan had, but I'm not well versed in the Hellish or Olympian side of Marvel. I would love to read your clarifications on the subject.
