- Ink-Suit Actor: Basically George Clooney as a fox.
- It's All About Me
- Jerk with a Heart of Gold: He has a hard time listening to others and has on various occasions gone behind his wife's back to get back into the feel of robbing. However, he loves her and the rest of his family and friends very much and is more than willing to risk his own life to save theirs.

- Off the Wagon: Actually stated by Mr. Fox when he's apologizing to his wife about stealing birds again.
- Papa Wolf: He's overall a very mellow guy, but you don't want to mess with his family.

- Sensitive Guy and Manly Man: The Manly Man to Kylie's Sensitive Guy.
- Significant Green-Eyed Redhead: Fox's fur is red so he technically counts for this trope.
- Small Name, Big Ego: He's an local newspaper columnist, and perpetually frustrated that nobody reads his column, and, in general, feels a need to be perceived as "fantastic", or he doesn't feel good about himself, even before he's done anything particularly heroic.

- Women Are Wiser: In the opening, Mrs. Fox suggested the smartest routes that would get her and Mr. Fox to the birds faster.
- Ambiguously Gay: Or transgender. Wears a feminine sweater and a cape made of lace. Also, when his father is talking about his mother being pregnant with him, Ash awkwardly points out that the baby could have been a girl. He even has markings on his fur that resemble eyeshadow or eyeliner, and when he has heart-shaped red lips from something he ate at the end of the movie, he looks completely feminine. He is upset to lose Agnes to Kris however, although this may just be his jealousy of Kris being The Ace, as his interactions with Agnes seem more like he considers her a friend than be interested in her romantically.

- Emo Teen: Before the Character Development.

- Kubrick Stare: He does this at one point in the sewers while Mr. Fox talks to him. It is quite unsettling.
- Sensitive Guy and Manly Man: Zig-Zagged, to say the least. See Kristofferson's folder.
- Super Heroes Wear Capes: His white outfit with a towel cape seems to be based on the White Cape comics he's seen reading.

- The One Who Wears Shoes: Out of the entire cast, Kristofferson is the only one to wear shoes.
- Pretty Boy: Kristofferson is somewhat like the fox version of this.
- Sensitive Guy and Manly Man: Zig-Zagged like crazy. Ash and Kristofferson practically take turns being the sensitive one to the other's manly man. Kristofferson is a polite, soft-spoken pretty boy, and meditates hours a day, but he also knows karate and he's extremely athletic. On the other hand, Ash is more emotionally delicate, border-line cross-dresses, and is described as "just different", but he also spits constantly, chases Agnes and strives to be the better athlete and earn his father's approval. Character development rounds them both out.
- Waif-Fu: He knows karate and is shown to be very skilled in it, in one instance using it to defend his cousin.
Kylie Sven Opossum
- Cloudcuckoolander: Perhaps the most blatant example of several.
- Hidden Depths: He apparently qualifies for incredible credit scores on his card because of how reliably he pays his bills.
- Misplaced Wildlife: A possum in what appears to be the English countryside.
- Nice Guy: Mr. Fox basically calls this out as his special talent in the "latin names" scene.
- Sensitive Guy and Manly Man: The Sensitive Guy to Mr. Fox' Manly Man.
- Why Did It Have to Be Snakes?: He admits to having a fear of thunder.
- Wingding Eyes: Gets spiral eyes at several points in the film.
Mr. Fox's lawyer, and owner of the flint mine.
- Hidden Depths: In Badger's office, he has a picture of a group of badgers in soldier uniform. Badger's skills with explosives might come from this military heritage.
- Mad Bomber
- Mr. Exposition: He gives the description of the main antagonists.
- Pyromaniac: He enthusiastically claims to be an expert in explosives, and he's not wrong.
- Undying Loyalty: He is very loyal to Mr Fox, who considers him to be his best friend.

Hired by Bean as his Secret Cider Cellar security guard. Maybe.
- Adaptational Badass: In contrast to his wimpy nature in the book, Rat proves to be one of the best fighters in the entire film, being able to go toe-to-toe with Mr. Fox with a hostage in hand, and is able to push past Stan Weasel and a chain-wielding Mrs. Fox with no trouble at all. The only reason Rat loses both fights he participates in is due to the environment around him.
- Adaptational Villainy: In the novel, Rat is cowardly, ruder and a reclusive drunk. He also had no connections to Bean, other than just living in his cellar. In the film, he and Mr. Fox have history, wields a switchblade and works for Bean as a guard of his cider. Rat is also sexist as he regards Mrs. Fox as the town tart "back in the day". He easily gets past Mrs. Fox and Weasel to kidnap Ash but is stopped by Mr. Fox after putting up a decent fight against him.
- The Alcoholic: Rat ended up getting so addicted to Bean's cider that he decided to take up a job protecting it.
- Badass Fingersnap: He's overly fond of using this to draw attention to himself.
- The Dragon: Fills this role for Boggis, Bunce, and Bean after they flush Mr. Fox and the other animals into the sewers.
- Death by Adaptation: He got away clean in the book, where his last scene is him screeching at Mr. Fox and Mr. Badger for stealing the cider as they leave. The movie gives him a High-Voltage Death while fighting Mr. Fox.
- Death Equals Redemption: Discussed with Rat. He did help them out, but he was "still just another dead rat in a dumpster behind a Chinese restaurant."
- Evil Sounds Raspy: As typical for Willem Dafoe.
- High-Voltage Death: Rat ends up getting electrocuted while battling Mr. Fox in the sewers. Though he hangs on long enough to taste some of Bean's finest cider, and to tell Mr. Fox where Kristofferson is being held.
- Hypocrite: In the book, he shrieks at Mr. Fox and Mr. Badger for being thieves and burglars when they steal a few jars of cider, even though he's doing it himself.
- I Work Alone: Unlike the other henchmen the three farmers have, Rat always goes after Mr. Fox and company by himself. Likely justified, as he's the only animal in the film that's in league with Boggis, Bunce, and Bean.
- Knife Nut: He owns a switchblade.
- Loners Are Freaks: In the words of Mrs. Fox, he's a psychotic rat.
- Near-Villain Victory: He likely would've gotten away from the other animals with Ash in tow if Mr. Fox hadn't shown up to confront him.
- Psycho for Hire
- Tall, Dark, and Snarky: Rat seems to consider himself this, though how much the third requirement (or the first) actually applies is questionable.
- Verbal Tic: As fond of similes as a pig is fond of mud.
- Would Hurt a Child: Rat's more than willing to kidnap Ash and take him to Boggis, Bunce, and Bean without a second thought.
- The Bully
- Fully Dressed Cartoon Animal
- The One Who Wears Shoes
- Unusual Euphemism: He calls Ash a wet sandwich as if it's a common insult.Beaver's Son: Why's your cousin such a wet sandwich?Kristofferson: I beg your pardon?Beaver's Son: What's that mean?Kristofferson: It means I didn't understand what you just said, a wet sandwich?Beaver's Son: Yeah, a wet sandwich. He's too short, he dresses like a girl, he's...(Gestures his hands) different.
A young girl fox in Ash's class. She has a crush on Kristofferson.
- Dark Is Not Evil: His fur might be black as night, but he has no ill will towards foxes or opossums.
- "Good Luck" Gesture: The Wolf raises one of his front paws in response to Mr. Fox does the same to him.
- Noble Wolf: He never tries to attack Mr. Fox and his crew, and goes on his own path after a brief interaction with them.
- No Name Given: He's only ever referred to as "The Wolf".
- One-Scene Wonder: He only appears out in the distance while Mr. Fox and his crew are escaping from the three farmers. After a brief interaction, he disappears, and is never seen or mentioned again.
- The Speechless: The Wolf doesn't verbally respond to any of Mr. Fox's questions, due to supposedly not speaking English or Latin.
Boggis, Bunce, and Bean
Three farmers that soon become antagonistic towards Mr. Fox after he steals from them. They are the main antagonists of the film.
- Berserk Button: Bean does not like the idea of giving up against a fox.
- Big Bad: Bean is clearly the leader of the three, and is much more intelligent, competent and intimidating than his cohorts.
- Big Bad Duumvirate: Well, Triumvirate. Despite Bean being the most antagonistic, in the eyes of the animals, all three are their greatest enemies.
- Big Eater: Boggis eats 12 chickens a day. Three for breakfast, three for lunch, three for dinner and three for dessert.
- Big, Thin, Short Trio: Boggis, Bunce and Bean (one fat, one short, one lean).
- Depraved Dwarf: Bunce is described as being around the size of a potbellied dwarf and his chin would be underwater in the shallow end of any swimming pool on the planet.
- Determinator: They really want to kill that fox. First they tried ambushing him with firearms, digging under the hill with pickaxes and shovels, bought construction vehicles to uproot the tree, detonated hole they dug with construction vehicles, called all 108 men under their farms to lay siege to the hill, and then flooded the animal's burrows with apple cider to flush them into the sewers, took Kris hostage, Bean's security Rat attacks the protagonists in the sewers, and ultimately try to stop Mr. Fox back at Bean's own farm before they escape. The trio finally seemed to give up at the end, but they are anything but done, and remain vigilant for the foxes return, as shown by the news.
- Evil Smells Bad: With his keen sense of smell, Mr. Fox can easily smell them out and run if they're too close. Boggis reeks of rotten chicken skins, Bunce stinks of goose livers, and Bean is always surrounded by the fumes of apple cider. Heck, Bean is the smelliest of the trio since he's never bathed in a long time and his hearing is bad due to earwax clogging his ears.
- Fat Bastard: Boggis. He is described to be as heavy as a baby rhinoceros.
- Flat Character: In the film, Boggis and Bunce who receive very little characterization and even fewer lines. They really just act as Bean's cohorts, agreeing to him, and acting as allies to pool their resources toward a mutual goal.
- Gargle Blaster: Bean's apple cider is described as "a homebrewed fiery liquor that burned in your throat and boiled in your stomach." It's also Impossibly Delicious Food, and Badger says it's like drinking melted gold, sunbeams and rainbows all at once.
- Hair-Trigger Temper: Bean.
- Informed Flaw: Badger, in addition to calling them the meanest and the nastiest, he also calls them the ugliest farmers in the history of the valley, when in all honesty, they don't look too much of an eyesore, especially compared to how they look in the book. Them being mean and nasty is true, though.
- Ink-Suit Actor: In the movie, Bean looks a lot like Michael Gambon, only skinnier.
- Jabba Table Manners: Averted with Boggis. While he hits a number of the common tropes being a Villainous Glutton and Fat Bastard who is snacking most of the time, he's not shown to be a particularly messy eater especially when compared to the animalistic sloppy eating of the protagonists.
- Jerkass Has a Point: Although they may have gone overboard, they weren't wrong in trying to get Mr. Fox, since he was stealing from them.
- Lean and Mean: Bean never eats any food at all and subsists entirely on his homemade apple cider. In the book, he's said to be "as thin as a pencil".
- Masochist's Meal: Bunce's food of choice is donuts filled with a paste made of mashed goose livers, which gives him "a tummy-ache and a beastly temper."
- More Dakka: The amount of ammunition they shot at the fox in the film is uncounted for.
- Named by the Adaptation: The book simply refers to them by surname, while the film adds given names: Walt Boggis, Nate Bunce, and Frank Bean.
- The Napoleon: Bunce. He is described as being so short, "his chin would have been under water in the shallow end of any swimming pool in the world".
- Playground Song: The local children made up a rhyme about them that stuck. "Boggis, Bunce and Bean / One fat, one short, one lean / These horrible crooks / So different in looks / Were nonetheless equally mean."
- The Stoic: Bunce maintains his sour expression throughout the movie. It's especially noticeable when Bean realizes they've been outsmarted and starts wrecking their trailer in a tantrum. Boggis is surprised at the outburst while Bunce is just sitting unmoved waiting for the Tantrum to subside.
- Terrible Trio: They are played like this, with Bean being the Big Bad, and Boggis and Bunce his sidekicks.
- Trademark Favorite Food: Boggis - boiled chicken smothered with dumplings; Bunce - homemade doughnuts with smashed up goose livers injected into them; Bean - strong alcoholic apple cider.
- Uncleanliness Is Next to Ungodliness: According to the narration, Bean never bathes ("he never even washed"), and he's hard of hearing because his ears are clogged with residue. (The other two are probably unhygienic too; Mr. Fox says in an early chapter that he can smell them so easily because they stunk.)
- Villainous Friendship: Only in the movie, in the book they can't go a minute without arguing with each other.
- Villainous Glutton: All three farmers, but especially Boggis, who eats three boiled chickens for every square meal of the day (plus dessert)."That's twelve in total, per diem."
- Weapon of Choice: Bean carries a Luger pistol, which is skinny and long much like himself. Boggis is armed with a double barrel shotgun, and Bunce carries a long range hunting rifle to accommodate his own small stature.
