Gonzo, also known as The Great Gonzo or Gonzo the Great, is a Muppet character known for his eccentric passion for stunt performance. Aside from his trademark enthusiasm for performance art, another defining trait of Gonzo is the ambiguity of his species, which has become a running gag in the franchise. He has been considered to be of various origins, including a Frackle, in his debut appearance in The Great Santa Claus Switch; extraterrestrial in Muppets from Space; or avian creature.
Developed and performed by Dave Goelz, Gonzo made his first appearance in the 1970 special The Great Santa Claus Switch, as the "Cigar Box Frackle". Originally a minor figure in The Muppet Show, he soon evolved into one of the franchise's primary characters. Gonzo has appeared in every Muppet film, including The Muppet Christmas Carol, where he portrayed author Charles Dickens and developed a double act with Rizzo the Rat.
