The Really Rottens

Really Rottens are the main antagonists in the Laff-a-lympics.

This team is composed of villainous characters. With the exception of Mumbly and the Dalton Brothers, all of the members are original characters, many of whom are based on various characters that appeared in cartoons and comics prior to Laff-A-Lympics. Originally, Muttley and Dick Dastardly were planned as the leaders of the Really Rottens; however, they could not appear on the show due to those characters being co-owned by Heatter-Quigley Productions.   In their place, Hanna-Barbera used the existing character Mumbly and created the new character Dread Baron. Prior to Laff-A-Lympics, Mumbly was a heroic detective rather than a villain on his original show. Following the character's revision as the villainous team leader, he remained a villain in Yogi Bear and the Magical Flight of the Spruce Goose, which was also Dread Baron's only other role The Dalton Brothers appeared in 1950s and 1960s shorts (including the 1958 short Sheriff Huckleberry Hound, which featured appearances by Dinky, Dirty, and Dastardly Dalton, as well as their other brothers Dangerous, Detestable, Desperate, and Despicable). However, they were given new character designs for the Laff-A-Lympics series. After Laff-A-Lympics, Dinky reappears in The Good, the Bad, and Huckleberry Hound with brothers Stinky (who bears a resemblance to Dastardly from Laff-A-Lympics), Finky, and Pinky.
