Breed: Mutt (referred to once as a bloodhound, pointer and hunting dog)
Original Appearances: Wacky Races TV show (1968)
Other Appearances: Dastardly and Muttley in The Flying Machines, Yogi's Treasure Hunt, Wake Rattle and Roll, and cameo appearances in Yo Yogi!, Duck Dodgers, and Dynomutt.
Biography: Muttley first appeared as the sidekick to nasty villain Dick Dastardly, and together they raced The Mean Machine in the Wacky Races. Later, Muttley and Dick Dastardly were joined by other medals of the Vulture Squadron trying to stop “Yankee Doodle Pigeon” in a World War I setting.
Powers: Muttley could not speak, but did have a distinctive snicker and a mushy grumble (which sounded something like “Rassafrassin' rastardly!”). In Dastardly and Muttley in Their Flying Machines, Muttley had the ability to fly for a brief period by spinning his tail like a propeller.
Group Affiliation: Vulture Squadron
Miscellaneous: Sometimes confused with Mumbly, who looked and sounded similar. Predecessors of Muttley included “Mugger” from Hey There, It's Yogi Bear, and Precious Pupp. As a member of Vulture Squadron, Muttley was particularly fond of his medals.
