Satyr
First appearing in "Marvel Family" #90 (unpublished, synopsis in Best of Alter Ego), Satyr is an evil incarnation of the god Pan that was banished from Earth 2000 years ago by Shazam. He faces the Marvel Family and attempts to replace Captain Marvel.
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. The Marvel Family are able to send them back although they are nearly sent themselves. This Satyr has superhuman strength, durability, and can control minds with his pipes, although Captain Marvel is able to break free of the music.
The Satyr Archibald was a member of the Monster Society of Evil, and graduated from Monster School with Mr. Mind (as he had briefly lost their memory and wanted a course to make them evil again) after capturing Billy Batson by accident by falling on him after he was knocked into the air, after an echo made Captain Marvel turn back, so as to graduate as the student needed to commit an evil deed. Billy was gagged, and his hands and feet are tied before he is taken of by Archibald. However while Archibald was beating him up before a class with a spiked knuckle-duster, Billy removed his gag, and summoned Captain Marvel who defeated Archibald. Only appearing in "Captain Marvel Adventures" #44.
