Behemoth (known more recently as Gene) is an orange monster who appeared occasionally as part of the troupe of Muppet monsters on The Muppet Show, and has also appeared in Muppets Tonight and the 2011 film The Muppets.
A notable moment for Behemoth was the musical number "Under My Skin", during which he tried to eatShakey Sanchez while singing the song. He made a comeback in The Muppets, both in a speaking role in the film and appearing in several of the promotional campaign spots and images.
In 2011, Bill Barretta performed the character in The Muppets, and in some of the trailers and promotional clips. Barretta has renamed the character "Gene", after his brother, animator and illustrator Gene Barretta.
