Main Characters

    Dudley Puppy
Voiced by: Jerry Trainor

  • Beware the Nice Ones: Dudley is a well-meaning, if brainless and destructive dog, but hurting his friends will get villains to surrender (as long as he notices that they're hurt). One example includes when R.I.T.A. (the toaster that Keswick invented) supposedly kills Keswick, he causes the giant robot to slip on the meatballs from cafeteria that he and Kitty were working at temporarily.
    • He also hates it whenever people touch one of his chew toys without asking him. Snaptrap learned this the hard way.
  • Catch-Phrase: "Hi-gee-gee!"
  • Kindhearted Simpleton: Say what you will about how careless he can be, but he truly means no harm and does try to help Petropolis from doom.
  • Large Ham: Being voiced by Jerry Trainor certainly helps matters.
  • LEGO Genetics: Dudley is a combination of every breed of dog ever, and somehow a bit of goat. Partially justified as a long enough blood line could mix every dog breed, the goat is something else.
  • Lethally Stupid: His stupidity is the cause of most of Kitty's injuries. And it's not just Kitty who's a victim of these. Very few characters are safe around Dudley.
  • Manchild: He lives in a multi-story tree house near his mom's house, and joins in with the kids when Snaptrap uses the "no hitting or killing near kids" rule to his advantage, doing kid related stuff along with crimes.
  • Nice Guy: While Dudley has his flaws, he's mostly outgoing and generally loves having Kitty as a partner.
  • Vitriolic Best Buds: With Kitty. He generally loves her as a partner, but often inadvertently injures her, though fortunately Kitty usually has no qualms against hitting him back.
  • Would Hit a Girl: Dudley doesn't have any problem hitting Kitty, even kicking her in the very same episode, also being seen giving her slaps, bites and, what could be, punches.
    • He also has no qualms against beating the Pageant queen to a pulp. Though, justified since he was convinced it was the Chameleon in disguise.

    Kitty Katswell
Voiced by: Grey DeLisle

Voiced by: Jeff Bennett

  • Cartoon Creature: Word of God says, "[T.U.F.F.] always knows [Keswick] will have the answer, but they just don't know what kind of animal he is." Its revealed in a later episode that Keswick is actually part of his own species, also called Keswick. They have quite an unusual life cycle, including a 'platypus phase' where they shoot toxic quills when they hiccup.
  • Gadgeteer Genius: He's made a machine that makes donuts out of thin air and redesigned D.O.O.M.'s lair using soup cans and a shark tank.
  • Last of His Kind: Possibly, since he is part of his own species. Part of their life cycle is growing a reptilian tail that breaks off and becomes another Keswick, who they must fight to the death.
    Keswick: There can be only ONE Keswick!
  • LEGO Genetics: Keswick has gills, webbed feet, lays eggs, has a pouch, and who knows what else.

    Herbert "The Chief" Dumbrowski
Voiced by: Daran Norris

  • Artificial Limb: The Chief has a bionic foot that makes him even cooler than he is already.

    Verminious Snaptrap
Voiced by: Matthew W. Taylor

  • Catch-Phrase: "It is I, Verminious Snaptrap!" and "I shall now plot my revenge!" He also often ends conversations with "Snaptrap out!"
    • "Start the car Larry!" whenever committing an act of petty theft.
  • Deadpan Snarker: Has his moments. Especially when Larry in involved.
  • Even Evil Has Standards: Snaptrap would never kill anybody on their birthday without letting them celebrate it first. "No one's THAT evil!"
    • When Snaptrap asks for suggestions on how to get revenge on the "Meanies" at the monotrail for not letting them ride, Francisco suggests that they eat them. Snaptrap flat-out states it's just "dark and disturbing".
    • The reason why Snaptrap tells the agents his latest plan is because he considers it rude not to.
  • Psychopathic Manchild: Most of his schemes are very petty and childish. For example, he tried to blow up the sun just to make popcorn in one episode.
  • Rodents of Unusual Size: He's a rat as tall as Agents Puppy and Katswell.
  • Speech Impediment: Has a lisp.
  • Token Evil Teammate: During his brief tenure as a T.U.F.F. Agent in "Snap Dad".
  • Too Dumb to Live: Is a mild example, particularly in "Mission: Really Big Mission" where his get rich quick scheme for the episode will also destroy the entire planet. Even The Chameleon calls him out on his embarrassing case of Didn't Think This Through.
  • Vocal Evolution: His voice was initially a bit deeper, but cracked constantly - but by the end of the first season his voice became more consistently high-pitched, lessening the Ed Wynn aspect of his voice.

    The Chameleon
Voiced by: Daran Norris

    Bird Brain
Voiced by: Rob Paulsen

  • Animal Gender-Bender: He has laid eggs for comedic effect.
  • Duck!: A running gag with many of his minions, including a duck named duck (and Skip). In "Bad Eggs", he shows an application form for being one of his henchmen, which includes a space for "weird name".
  • Only Sane Man: When you compare him to Snaptrap and The Chameleon.
  • Rail Enthusiast: He really likes taking the bus and he even memorized different bus schedules. Only because he can't fly.
  • Surrounded by Idiots: Not only when dealing with his henchmen, but when he teams up with Snaptrap and The Chameleon.
  • Younger Than They Look: According to "A Doomed Christmas" he's 23, though that doesn't stop everyone else from thinking otherwise.

    Quacky the Duck
Voiced by: Matthew W. Taylor

    The Sharing Moose
Voiced by: Jeff Bennett

  • The Dragon: He is Quacky's main helper and muscle.
  • Odd Name Out: Among Quacky's co-hosts, the Sharing Moose is the only one whose name is not even phonetically alliterative.
