List of Wacky Races characters

Ann and Clair
Ann and Clair are Sawtooth's log cars. Sawtooth uses them to carry his logs in. They play as Annie and Clarabel in Wacky Races/Thomas parodies.

Big Gruesome
Big Gruesome is one of two horror-themed racers in Wacky Races. Together with Little Gruesome, they drive the Creepy Coupe, the #2 car. He is a lurching, huge humanoid monster modeled after the Frankenstein monster and Lurch. He speaks like Boris Karloff. He was originally voiced by Daws Butler, and currently by Jim Cummings.

Big Gruesome's character reflects that of Bill from Thomas and Friends, Burke from TUGS and Dingo from Sonic. His rareware theme is Donkey Kong 64's Creepy Castle.

Blubber Bear
Blubber Bear is Lazy Luke's sidekick in Wacky Races. Due to Luke's reckless driving, Blubber Bear is usually cowering in fear as he and Luke race past everyone. He is voiced by John Stephenson.

Blubber Bear's character reflects that of Henry from Thomas and Friends, Warrior from TUGS and Big from Sonic the Hedgehog. His rareware is Donkey Kong 64's Fungi Forest.

Brenna Bubbles
Miss Brenna Bubbles is shy, cute, and speaks with a soft voice. She's a vegetarian. The car she drives is known as the Seaside Sedan. She is in love with one particular racer: Rufus Ruffcut. She tries everything she can to help the other racers in distress.

Bully Brothers
The Bully Brothers were the Hooded Claw's identical twin henchmen on The Perils of Penelope Pitstop. Mel Blanc did their voice but it was the same voice for both so when they talked it just sounded like one voice coming out of both of them.

Dick Dastardly
Dick Dastardly is one of Hanna-Barbera's most recognized villains. A perpetual cheat and greedy schemer, Dastardly is always paired with sidekick Muttley. He debuted as the antagonist of Wacky Races, where his vehicle was the Mean Machine (Double Zero). Then he was put into his very own cartoon of his very own, Dastardly and Muttley in Their Flying Machines, as a WWI-era flying ace.

Dastardly's most famous appearances are main character in the series Wacky Races (his initial appearance) and its spin-off Dastardly and Muttley in Their Flying Machines. He is essentially a caricature of the English actor Terry-Thomas, and of Professor Fate, a comic villain played by Jack Lemmon in the film The Great Race. The character was voiced originally by Paul Winchell, then by Rob Paulsen and currently by Jim Cummings. Winchell and Cummings have shared another role: Tigger from Winnie-the-Pooh stories. Chikao Ōhtsuka does the voice of Dick Dastardly in Japanese. In Wacky Races, Dastardly was one of the drivers who competed in each episode for first place in a long and hazard-filled cross-country road rally. As his name implies, Dastardly aimed to win solely through cheating and trickery. His race car, named The Mean Machine featured all sorts of devious traps for him to use against his opponents. As Wacky Races is inspired by the film The Great Race, so was Dastardly derived from the film's chief villain, Professor Fate, played by Jack Lemmon. Dastardly in this series wore old-fashioned racer's gear — a long blue overcoat, long red gloves, and a large striped hat with driving goggles attached, and sporting a handlebar mustache. Dastardly was aided in his schemes by his sidekick, a scruffy dog named Muttley who had a distinctive wheezy laugh, heard most often when Dastardly's schemes failed.

Despite Dastardly and Muttley's attempts, the "double-dealing do-badders", as the opening narration of Wacky Races describes them, failed to win a single race. Dastardly's plans were always foiled either by his or Muttley's incompetence, the actions of another racer, or sheer bad luck, resulting in Dastardly crossing the finish line last, if at all. On some occasions Dastardly is very close to winning but will fail at the final hurdle. On one occasion, in an episode which was voted the worst of the series, Dastardly actually won the race, but it was revealed he had cheated by extending the nose of his car (even though the actual finish shows no such cheating, implying that the judges possibly had the replay footage altered out of bias. Although it should be noted that in the DVD release of this scene the photo finish was covered with smoke, thereby adding even more questions to this scene). Another time Dastardly has an opportunity to win legitimately, but stopped in front of the finish line to pose for his picture as it was a photo finish. Once he comes close to winning the race, but stopped to sign an autograph for Muttley, ending up in fourth place again

Often it appears that if Dastardly had not bothered to cheat he may have won fairly. Upon tasting defeat, Dastardly would utter his catchphrase: "Drat, drat, and double drat!", "Triple drat!" and even "Curses, foiled again!". His other main catchphrase was "Muttley, do something!". Excluding Dastardly and Muttley, all of the other racers won at least one Wacky Races.

Dick Dastardly's rareware theme is Conker's Bad Fur Day's Boss Theme.

Dick Dastardly's character reflects that of Diesel from Thomas and Friends, Zorran from TUGS and Dr. Robotnik from Sonic the Hedgehog

The General is an unseen character on Dastardly and Muttley in Their Flying Machines. He is usually heard as an indistinct voice from Dick Dastardly's telephone.
