First appearing in "Marvel Family" #90 (unpublished, synopsis in Best of Alter Ego), Satyr is an evil incarnation of the god Pan that was banished from Earth 2000 years ago by Shazam.
Another Satyr appears in "Marvel Family" #21 along with a two-headed Hydra and many eyed Argus, as a Trio of Terror summoned from the Netherworld by three carnival brothers using a stolen spell book, who have to return in 24 hours unless three replacements are sent.
