Dick Dastardly and Muttley plot to get rich by often engaging in several plans like counterfeiting money or gems, scamming people by claiming they are Nigerian princes, disguising as hobos, taking control of a country or simply robbing banks.
- Richard "Dick" Dastardly (voiced by Jim Cummings) - a greedy and somewhat self-absorbed outlaw who often engages in several villainous acts to become wealthy, only to backfire thanks to his incompetence mixed with big ego and Muttley's constant non-helping.
- Muttley (vocal effects by Frank Welker) - Dastardly's scruffy but loyal pet dog and sidekick who prefers to slack off and disobey rather than helping him and often snickers at the expense of his owner's misfortune, whenever he gets in trouble, injured or abused.
- Esmeralda (voiced by Kath Soucie) - a seductive model who is secretly in league with Dastardly and is in love with him, helping him with his schemes, even though she is more cautious about them.
- Klunk and Zilly (voiced by Brad Garrett and Rob Paulsen, respectively) - Dastardly's occasional crew who aid him to achieve his goals, even if they indirectly help him to fail due to their pure incompetence.
- The Great Fondoo (voiced by Maurice LaMarche) - a crazy magician who is more succesful than Dastardly due to his magical powers and his more efficient methods, even if it backfires on him due to his inability to cast the right spells.
- Magic Rabbit (vocal effects by Frank Welker) - Fondoo's pet rabbit who is more of an annoyance rather than being evil and his only word is "Brak".
- Orful the Octopus (voiced by Tom Kenny) - a fanged octopus who is able to walk in land and is rather TBD.
- Daisy Mayhem (voiced by Kari Wahlgren) - a corrupt and aggressive hillbilly who somehow has superhuman strength and often clashes with Dastardly due to her rather stupid behavior in contrast with his malicious and scheming attitudes.
- Sooey Pig (vocal effects by Frank Welker) - Daisy's sloppy pet pig who likes to get dirty.
- Penelope "Penny" Pitstop (voiced by Danica McKellar) - a vain and danger-prone Southern-accented woman who is one of Dastardly's rivals at Wacky Races and tries to disband Dastardly's illegal activities as an undercover spy, even if it implies ending up in his clutches.
