Voiced by: George Clooney
- Affectionate Nickname: Mrs. Fox calls Mr. Fox "Foxy."
- Alliterative Name: The school's records indicate his name is F.F. Fox.
- Badass Boast: "Your tractors uprooted my tree. Your posse hunted my family. Your gunmen kidnapped my nephew. Your rat insulted my wife ó and you shot off my tail. Iím not leaving here without that necktie."
- Character Tics: Whistles and clicks his tongue as his "trademark".
- Cunning Like a Fox: It's downplayed, but he's actually very intelligent. He knows the Latin names of all but one of the main characters' species, for instance, and he plans his escapades like a Chess Master.
- Fantastic Foxes
- Fatal Flaw: His refusal to listen to the advice of others.
- Glasgow Grin: The scar given to him by his wife looks like this in some shots.
- It's All About Me
- Jerk with a Heart of Gold
- Loveable Rogue
- Off the Wagon: Actually stated by Mr. Fox when he's apologizing to his wife about stealing birds again.
- Red-Headed Hero
- Scars Are Forever: Mr Fox's tail becomes detachable, permanently. Also the cut Mrs. Fox gives him that remains throughout the film.
- 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 he feels a need to be perceived as "fantastic", or he doesn't feel good about himself, even before he's done anything particularly heroic.
- Too Dumb to Live: Mr. Fox gets carried away sometimes, edging into this trope.
- Why Did It Have to Be Snakes?: He has lupophobia (fear of wolves) and gets apprehensive at the mere mention of them.
Voiced by: Meryl Streep
- All Girls Want Bad Boys: Partly. Though it made her regret marrying him, Felicity can't help falling for his "fantastic" wild animal nature.
- Alliterative Name: Felicity Fox.
- Beware the Nice Ones: She viciously scratches Mr. Fox's face after it's revealed that he lied to her.
- Good Parents: Mrs. Fox is a good mother, handling Ash's moods very well, though she has moments where she must warn Ash to mind his tongue.
- The Conscience: She acts as the voice of reason and conscience to her husband's more reckless ways.
- Mama Bear: When Ash is being kidnapped by Rat, Mrs. Fox shows a courageous motherly attitude, even to the point of using violence to protect her son, if necessary.
- My Girl Is Not a Slut: Heavily implied that before she settled down with Mr. Fox, Mrs. Fox very much averted this.
- Nice Girl: She is cautious and responsible in her personality.
- Smurfette Principle: The only one of the main characters who's a female.
- Stacy's Mom: Some of Ash's classmates have commented on her attractiveness.
- Women Are Wiser: In the opening, Mrs. Fox suggested the smartest routes that would get her and Mr. Fox to the birds faster.
Voiced by: Jason Schwartzman
- Ambiguously Gay: Or trans. Wears a feminine sweater and a cape made of lace. Also, when his mother is talking about being pregnant with him, Ash awkwardly points out that the baby could have been a girl. 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.
- Bratty Half-Pint: To Kris at first, even though Ash is older.
- Character Tics: Twitches his ear and/or spits when aggravated.
- Emo Teen: Ash before the Character Development.
- Goofy Print Underwear
- Green-Eyed Monster: The main reason for his initial dislike of Kristofferson is because everyone, including his father, describe him as a natural.
- Jerk with a Heart of Gold: He's not nice to Kristofferson at all, but warms up to him at the end.
- Man in White: A younger version, which represents his odd personality.
- Sensitive Guy and Manly Man: Zig-Zagged, to say the least. See below.
- 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 Unfavorite: Ash considers himself this, seeing himself inferior to his athletic and more popular cousin, and his father's attitude towards said cousin doesn't help.
- "Well Done, Son!" Guy: All he ever wanted was his father's approval.
- Wholesome Crossdresser: Ash enjoys wearing a feminine wool sweater and a lacy cape.
Voiced by: Eric AndersonKristofferson is Mr. Fox's nephew (from his wife's side) and cousin to their son Ash. He stays with his aunt and uncle due to his father having double pneumonia.
- The Ace: To put it simply, he's a natural.
- Big Little Brother: Noticeably taller and more mature than his older cousin Ash.
- Fully Dressed Cartoon Animal
- Meaningful Name: His last name, "Silverfox", references his gray/silver fur.
- Nice Guy: A consistently polite person, who at one point states he hates being dishonest to people.
- 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
Voiced by: Wally Wolodarsky

Voiced by: Bill MurrayMr. 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.
- Vitriolic Best Buds: Despite his arguing with Mr. Fox about his reckless behavior, he nonetheless trusts him and they are best friends.
Voiced by: Willem DafoeHired by Bean as his Secret Cider Cellar security guard. Maybe.
- 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."
- Knife Nut: He owns a switchblade.
- 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.

Boggis, Bunce, and Beans
Bogis Voiced by: Robin Hurlston
Bunce Voiced by: Hugo Guinness
Beans Voiced by: Michael GambonThree farmers that soon become antagonistic towards Mr. Fox after he steals from them.
- Badass: Bean is a perfect shot with his gun and is the only one of the three who can come close to Mr. Fox in cunning.
- 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 Triumvirate: Despite this, in the eyes of the animals, all three are their greatest enemies.
- Big Eater: Boggis eats 12 chickens a day.
- Big, Thin, Short Trio: Boggis, Bunce and Bean (One fat, one short, one lean).
- Fat Bastard: Boggis.
- Hair-Trigger Temper: Bean.
- Jerkass Has a Point: Although they may have went overboard, they weren't wrong in trying to get Mr. Fox, since he was stealing from them.
- Lean and Mean: Bean.
- The Napoleon: Bunce.
- The Stoic: Boggis and Bunce, especially Bunce, whose sour expression never changes once.
- Terrible Trio: They are played like, with Bean being the Big Bad, and Boggis and Bunce his sidekicks.
- Trademark Favorite Food: Boggis - chicken; 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 Glutton: All three farmers, but especially Boggis, who eats three chickens for every square meal of the day (plus dessert)."That's twelve in total, per diem."
