Although he appeared as early as The Muppet Show: Sex and Violence pilot, he was not named until the culinary-themed Panel Discussion in episode 119, in which Vincent Price introduced him as "one of the world's greatest eaters." He proceeded to eat Pierre LaCousse, one of the world's greatest chefs, before starting in on Kermit.
He also played the role of Fielding the Butler in "Sherlock Holmes and the Case of the Disappearing Clues", the UK Spot in episode 103 (in which he ate almost everything, including the maid and Dr. Watson).
Although Gorgon appeared primarily during the first two seasons of The Muppet Show, he made one appearance in the third season as a drummer in episode 318.
His looks often changed between episodes. Sometimes the horns on his head were left off or replaced with ears instead, and in episode 204, he was given an elongated, worm-like nose for "The Glow-Worm" sketch.
The character greatly resembles Big V, another large, long-nosed monster who appeared in The Muppets' variety show acts in the 1960s.
