The Scariest Muppets Ever

It's only fitting that the scary Uncle Deadly made his debut on an episode of The Muppet Show hosted by Vincent Price. This sepulchral creature was once a perfomer in the theater that the Muppets now use, until he was murdered on opening night... by the critics. His malevolent spirit has haunted the theater ever since. Voiced by Jerry Nelson, Uncle Deadly showed up sporadically on the TV show and even went with Kermit to host The Tonight Show. He's also seen in 2011's new The Muppets movie.

Crazy Harry is one of those Muppets that reflects a very particular period in time - he's kind of like a felt stereotype of a 70s terrorist, all wild eyes and cartoonish explosives plunger. All he needs is a kidnapped Patty Hearst muppet. Harry was the assistant to the Great Gonzo in many of his daredevil stunts, and when he shows up you know something is going to be demolished in exceedingly violent fashion. Collateral damage? Who cares, they're puppets.

Over the years, Big Bird's imaginary friend has been redesigned a bit to look less creepy, but when he first showed up on Sesame Street in 1971 he was a nightmarish apparition. For some reason, Henson's designers chose to make the enormous hairy elephant have a pair of yellow eyes like a Hep C sufferer. Couple that with flowing, scary eyelashes and his trademark voice and you had a creature that would haunt your dreams. Special mention is owed to a skit from this period that has children crawling beneath his pendulous belly.

Fraggle Rock was one of Jim Henson's most unique creations, a sprawling ecological parable with a massive cast. There were some truly horrifying entities inhabiting the world of the Fraggles, but none freaked us out as much as Wander McMooch. This toadlike con man was a long-time nemesis of Marjorie the Trash Heap, and whenever he showed up you knew that some kind of negative shenanigans would erupt. His visual design was deeply unpleasant, like a greasy homeless dandy with reptile skin.
