Voiced by: Peter Sallis; Ben Whitehead (Grand Adventures and TV spots)
- Absent-Minded Professor: He's an inventor who's as eccentric as he is brilliant.
- All Love Is Unrequited: In Grand Adventures, he shows no romantic feelings for Felicity Flitt even when she starts developing interest in him in Episode 3, and he's rather shocked when he accidentally proposed to her and spends much of Episode 4 trying to undo this. He's shown to be quite relieved when Flitt gets back with Duncan McBiscuit in the end.
- Anti-Hero: As the Were-Rabbit.
- Bald of Awesome: He has no hair and his inventions can be pretty impressive.
- Hair Today, Gone Tomorrow: According to Curse Of the Were-Rabbit, he had a full head of long hair when Gromit was a puppy. He lost it by the time Gromit finished college.
- Brilliant, but Lazy: Wallace is indeed a great inventor, but many of his inventions are usually designed to make everyday tasks easier for him.
- Bungling Inventor: Most of his inventions backfire on him.
- Butt-Monkey: Gets hurt by his own inventions.
- "CheeeeEEEEeeeeeeeese!" (with Wallace's trademark excited hands).
- Also, once things inevitably fall apart, Wallace's "GROMIT! HELP! DO SOMETHING!," or the less emphatic "Gromit! Do something, lad!" There's no ceiling on how many times Wallace will say this in a single episode.
- "It's all right, Gromit! Everything's under control!"
- Character Tic: Often waves his fists whenever he's excited.
- Ditzy Genius: He's undeniably smart, but he lacks common sense.
- Did Not Get the Girl: Despite Ship Tease with three female characters in three different stories, Wallace has never gotten together with anyone.
- Disney Death: As the Were-Rabbit.
- Heterosexual Life-Partners: With Gromit - they're hardly ever seen apart and always have each others' backs.
- Gadgeteer Genius: Zigzagged. Wallace is without a doubt a brilliant mind and has plenty of contraptions to prove it. However, there have been instances where some of his designs have come out imperfect.
- Genius Ditz: He's a terrific inventor, but a bit slow to pick up on some things that are more obvious to others.
- Identical Grandson: To Witlace in Grand Adventures.
- It's All About Me: A minor version of this trope. A reoccurring theme in the Wallace & Gromit shorts, and the movie, is that Wallace is often so wrapped up in his inventing that he doesn't notice how his actions upset (or outright harm) Gromit. Wallace is just too clueless to realize.
- Mad Scientist: A heroic example. Wallace's inventions range from malfunctioning Rube Goldberg-esque devices to clever and groundbreaking gadgets which also have a tendency to malfunction. Notably, he seems more competent in the feature film than in most of the shorts.
- Meaningful Name: Wallace can be diminutised as "Wally", a slang term for a naïve or foolish person.
- New Job as the Plot Demands: A window-cleaner in A Close Shave, and a baker in A Matter of Loaf and Death. In Curse Of the Were-Rabbit, a humane pest-control business. In the Grand Adventures games, a beekeeper, runner of an indoor holiday resort, ice-cream vendor and detective.
- Nice Guy: Perhaps the friendliest and most mild-mannered version of the Mad Scientist trope out there!
- Non-Action Guy: Compared to Gromit, who usually has to be the one to pull Wallace out of a tight spot.
- Oh, Crap!: Has this reaction a lot, especially when his inventions go haywire. Most notably when he realizes he's the Were-Rabbit.
- In the first short, it's when he realizes he forgot to bring crackers.
- Our Werebeasts Are Different: When he turns into the Were-Rabbit.
- Pungeon Master: Makes puns frequently.
- Science Hero: More often then not turns to science for any given problem.
- Too Dumb to Live: More and more after each short, though he did find out Piella was a serial killer when Gromit shows him the bomb in A Matter of Loaf of Death.
- Took a Level in Jerkass: Wallace can be stubborn or selfish on occasions but they are all inadvertently and unintentional.
- Trademark Favorite Food: Cheese, particularly Wensleydale, is Wallace's favorite, which he always has with crackers. Also, his breakfast of choice seems to be jam on toast.
- Undying Loyalty: After Gromit is framed for murder and awaiting life imprisonment, Wallace wastes little time concocting a breakout. He also tries to save Gromit when he gets captured by Monty Muzzle.
- Ace Pilot: As seen in A Close Shave and The Curse of The Were-Rabbit in a Shout-Out to Snoopy in Peanuts.
- Action Pet: He could technically be considered Wallace's pet and does a lot more traditionally heroic things than his master.
- Badass Adorable: Gromit isn't just a loyal dog, he's so fiercely loyal that it'll take a lot to take him down. He's also quite cute.
- Beleaguered Assistant: He tends to wind up on the wrong end of some of the things Wallace instigates.
- Big Ol' Unibrow: Gromit never speaks, so this is the only way you know what he's feeling. It's really incredible, the emotion you can wring out of an artfully-squashed bit of plasticine...
- Butt-Monkey: Misfortunes happen to Gromit a lot.
- Civilized Animal: He's bright and perceptive, but is treated as an ordinary dog. He also seems to have the psychology of a dog, if his devotion to Wallace is any indicator.
- Cloud Cuckoolanders Minder: He spends a lot of time rescuing Wallace from his own predicaments.
- Deadpan Snarker: While Gromit is usually a Silent Snarker, the duo's mutual diary - published as the Cheese Lover's Yearbook - has little typewritten notes expressing Gromit's reaction to whatever is happening. After the entries for "A Close Shave":Wallace: Relieved to have come out of this in one piece.
Gromit: Instead of several hundred, like Preston. - G
- The Engineer: Often has to build and use the inventions that Wallace dreams up.
- Even the Dog Is Ashamed: This is his constant reaction to Wallace's antics, usually either a Face Palm or a Disapproving Look.
- Expressive Ears: His second most-expressive feature.
- Heterosexual Life-Partners: With Wallace - they're hardly ever seen apart and always have each others' backs.
- Hypercompetent Sidekick: He is Wallace's assistant and is responsible for at least some of the daily work of running the household, helping with Wallace's inventions, and pulling Wallace's fat out of the fire. In Project Zoo, he's even the main playable character.
- Identical Grandson: To Gimlet in Grand Adventures.
- Intellectual Animal: He's very smart!
- In Touch with His Feminine Side: Gromit is a very sensitive individual who isn't afraid to cry when things really get bad, and has a love for knitting.
- Meaningful Name: A grommet is a rubber ring used to seal the edge of a hole, to stop it chafing the insulation of wires passed through the hole.
- Nice Guy: Gromit is good-hearted and eternally loyal as well as protective towards Wallace.
- No Mouth: Most likely the reason why he's The Speechless.
- Despite being the assistant and Wallace getting top billing, Gromit is always the more focused one.
- He is the player character in Project Zoo.
- Only Sane Man: Unlike Wallace, Gromit is fully aware of the situation at hand and has to take it upon himself to come out on top.
- Silent Partner: He is Wallace's fellow worker and never speaks.
- Silent Snarker: The Trope Codifier and current page image. Being wordless doesn't mean he can't convey sarcasm.
- The Speechless: He never speaks, save for the occasional bark. But that's not to say he's inexpressive.
- Four Legs Good, Two Legs Better: Zig-Zagged. Gromit tends to alternate between walking on his hind legs, and walking on all fours.
- Undying Loyalty: Even upon the discovery of Wallace being the Were-Rabbit, Gromit is fiercely loyal to his master.Victor Quartermaine: Your loyalty is moving; sadly, you won't be.
- Everything's Better with Penguins: Subverted, as he's a villain despite being a penguin.
- Evil Is Petty: Gets on Gromit's bad side and drives a wedge between him and Wallace all because he wanted him out of the way.
- Evil Counterpart: To Gromit. Both of them are Intellectual Animals who never say a word. However, Gromit is unshakably loyal to Wallace, while Feathers only befriends Wallace as a means of getting rid of Gromit and using Wallace as a means of stealing a priceless diamond.
- Intellectual Animal: Besides modifying the controls of the Techno Trousers, he created his own wide variety of complex inventions as seen in "Project Zoo".
- Laser-Guided Karma: What better place to put a criminal penguin than the Zoo?
- Silent Antagonist: He never says a word and is the main villain of The Wrong Trousers and Project Zoo.
- The Stoic: His lack of facial expressions is quite unnerving. If it wasn't for the sinister music playing whenever he's scheming, you'd think he was just a random anthropomorphic penguin.
- The Voiceless: Feathers does not speak.
- Would Hurt a Child: In "Project Zoo" he threatens the lives of baby zoo animals in order to force their parents into working for him.

- Adaptational Jerkass: In the comic The Curse of the Ramsbottoms, she's aware of her fiancé Rhett's activities, and when she catches Wallace and Gromit snooping around Rhett's secret study, she throws them out of her house. To add insult to injury, she announces that after she marries Rhett, she and him will run a beauty company that will run Wallace's favorite cheese company out of business for life. This is Wendolene's only role where she acts as a mean-spirited jerkass.
- Girl of the Week : She's Wallace's love interest for the short.
- Guilt-Ridden Accomplice: She goes along with Preston's plot, but doesn't like the lengths to which he carries it.
- Ur-Example: The first (and certainly not the last) Love Interest for Wallace.
Preston the Bulldog
- A.I. Is a Crapshoot: Preston, the villain, was once a good robot dog that according to Wendolene suddenly became evil.
- Big Bad: Of A Close Shave.
- Expy: Of the first T-800.
- HeelFace Turn: At the end, where he's back to normal after being rebuilt.
- Kubrick Stare: Gives one while chasing Wallace and Gromit after ramming the back of their motorcycle.
- Adaptation Personality Change: A perpetually eating Genius Ditz in the Wallace & Gromit series. An anthropomorphised Loveable Rogue in his own series.
- Anthropomorphic Shift: While having some moments of brilliance, Shaun was more a standard destructive animal in A Close Shave. When branched out into his own show, Shaun evolved into a level of human-like intelligence almost on par with Gromit, was granted a more expressive personality and more became far more liable to walk on his hind legs.
- Breakout Character: He has his own series.
- Intellectual Animal: A mild case in Wallace & Gromit, a full on example in his own series.
- Loveable Rogue: In his own series.
- Punny Name: Shaun rhymes with "shorn" (as in "sheared") in non-rhotic varieties of English.
- Silent Snarker: Like Gromit, he has his moments of conveying sarcasm.
- The Speechless: Although he does bleat quite frequently.
Lady Campanula Tottington
Voiced by: Helena Bonham-Carter
- Friend to All Living Things: She is rarely unfriendly to anyone or anything. She's the only member of the town who's saddened by the supposed "death" of the Were-rabbit, and strongly disapproves of Victor Quartermaine's love of hunting.
- Heroes Want Redheads: She is a redhead and Wallace falls for her.
- Nice Girl: She's very friendly and hates for anything to be harmed, which attracts her to Wallace's humane pest control service and puts her at odds with Victor.
- Punny Name:
- "Tottie" is UK slang for an attractive young woman.
- Even more subtly, "Campanula" is the Latin name for the harebell. Just in case there weren't enough bunny puns in this movie.
- Single Woman Seeks Good Man: Tottington has a secret crush on Wallace, who can be considered the most mild-mannered, respectable person there is.
Lord Victor Quartermaine
Voiced by: Ralph Fiennes
- Bald of Evil: Victor wears a toupee to cover his baldness and is the antagonist of the film.
- Big Bad: Of The Curse of the Were-Rabbit.
- Butt-Monkey: Nothing ever goes right for Victor Quartermaine, especially during the climax. Aside from failing to poach the Were-Rabbit, he also gets sprayed in the face with weed killer, knocked into a cotton candy machine, and finally stuffed into a Were-Rabbit suit before getting chased away by an angry mob.
- Egomaniac Hunter: He relishes the rabbit problem Lady Tottington has, as it gives him a chance to stretch his hunting skills and hopefully impress her. The Were-Rabbit is just gasoline on his flame.
- Evil Poacher: He prefers traditional manners in dealing with Pest Control, and is the main antagonist of the film.
- Expy: He's a well-respected Egomaniac Hunter who is in a love triangle with the two romantic leads. Essentially, he's the Aardman version of Gaston.
- Gold Digger: Victor's already a rich nobleman, but he was wooing Lady Tottington solely for her money.
- It's Personal: Discovering the Were Rabbit is Wallace, who has been gaining Lady Tottington's affections, only makes him even more vehement about blowing its brains out.
- Jerkass: He's extremely snobby and stuffy, never passes any opportunity to mock Wallace, particularly for his humane pest control methods, and doesn't hesitate to try and kill the Were-Rabbit when he realises it's actually Wallace.
- Large Ham: On top of being arrogant and opinionated, he has an extremely pompous manner of speech.
- Sore Loser: Seeing Wallace engaging in friendly conversation with Lady Tottington displeases him to say the least. What does he do in response? Create a road block and challenge Wallace to a fist fight.
- The Rival: He and Wallace are both interested in Lady Tottington, although for different reasons.
- Uncertain Doom: The last we ever see of Quartermaine is him being chased away by an angry mob. It's unclear whether he was chased out of town or worse.
Voiced by: Peter Sallis
- Animal Talk: One of the only ones in the franchise.
- Continuity Nod: An odd case in that pretty much every single line of dialogue spoken by him is a quote taken either from earlier in The Curse of the Were-Rabbit, or from one of the three shorts preceding it.
- Helium Speech: His voice is really Wallace's in higher pitch.
Voiced by: Sally Lindsay
- Bitch in Sheep's Clothing: She may act sweet and caring most of the time, but is a ruthless serial killer out for revenge.
- Disproportionate Retribution: She lost her job as the Bake-o-Lite bakery spokeswoman when she became too heavy to use the balloon featured in all their commercials. Because of this, she decides to murder a baker's dozen worth of bakers to punish all bakers for producing the rich foods that she got fat eating.
- Family-Unfriendly Death: Being eaten alive by crocodiles at the zoo, after she weighs down the balloon on which she's attempting to escape. Thankfully Gory Discretion Shot is in play.
- Fat Comic Relief: Though one of the darkest villains in the series, they still manage to make a fair amount of humor concerning her weight problem.
- Formerly Fit: Used to be a lean and skinny woman. However, her binging in bread is what made her so overweight to this day.
- Hurricane of Puns: She makes many, incredibly unsubtle jokes on how she's going to murder Wallace.
- I Was Quite a Looker: Before she gained a lot of weight.
- Kick the Dog: She literally kicks her dog Fluffles, although in such a way that it could be interpreted as a hard nudge.
- Knight of Cerebus: Few of her qualities are played for laughs, and unlike most of the villains, has succeeded at murdering innocent people.
- Never My Fault: Considers her weight problems to be the fault of bakers for producing fattening treats rather than herself for eating too many of them.
- Serial Killer: She was responsible for the deaths of twelve bakers, all for a petty reason, no less.
- White-Dwarf Starlet: Piella Bakewell. Wallace recognizes her as the spokeswoman for Bake-O-Lite Bread, but she was fired as the "Bake-O-Lite Girl" when she became too heavy to fly the balloon they used in advertising.
Voiced by: Melissa Collier
- Break the Cutie: Fluffles comes pre-broken, evident from the trembling. Though she eventually overcomes it.
- Civilized Animal: Fluffles is capable like Gromit, though she's generally shown on all fours for much of the film. Notably, her moments of bipedalism happen either out of the sight of her abusive master, or at the film's end when she finally stands up to her and remains bipedal for the rest of the film.
- Cute Mute: Like Gromit, she never speaks (though she makes more sounds, like whimpering). She's also quite adorable.
- The Dog Bites Back: Fluffles, the mistreated poodle belonging to the 'Cereal Killer', not only bites back but then proceeds to take the killer on with a fork lift truck
- Nice Girl: Fluffles is very timid but kind. Gromit ends up falling in love with her when she returns his possessions (by picking them out of the trash no less) when Piella throws them away.
Grand Adventures characters

- Small Name, Big Ego: She thinks highly of her garden and her dogs.
- Cloudcuckoolander: He frequently believes he's in a war.
- The Cloudcuckoolander Was Right: The town really was attacked... just not in the way anyone expected.
- Multiple-Choice Past: He also seems to have difficulty remembering what branch of the military he was in from chapter to chapter. In the first chapter he claims to have been in the artillery, but in the third he claims to have been in the RAF.
- Jerkass: He locks up anyone (and anything) that he considers to violate the law. The main plot of The Bogey Man involves him trying to close the local country club mostly because he wasn't invited to it.
- Serious Business: The Constable tends to take his police work seriously.
- Butt-Monkey: No matter what kind of crazy plot Wallace and Gromit are caught up in, it always ends up inconveniencing him somehow. He lampshades this in the final episode.
- Captain Ersatz: He seems to be W&G's version of Apu from The Simpsons.
- Identical Grandson: To Rory McBiscuit.
- Jerk with a Heart of Gold: Mostly to Ms. Flitt, but he does save Wallace and Gromit from falling at the end of The Last Resort.
- Bitch in Sheep's Clothing: He opens up a fundraiser on the claims of rebuilding a dog shelter. It's actually a scam to swindle money out of the townsfolk and using actual strays as labor for the rides.
- Kick the Dog: Monty kidnaps strays dogs to move his ride the Muzzler. Some of his dialogue implies that a couple of dogs died because of this.
- Laser-Guided Karma: He lands in jail, and the only thing keeping him company are the two mean dogs from the previous episode.
