"There’s always a chance, Doctor, as long as one can think."
Voiced by: Barrie Ingham

A detective, based on the fictional sleuth Sherlock Holmes. His main goal is to get Professor Ratigan behind bars and rescue Olivia Flaversham's father, while simultaneously preventing a royal assassination.
  • Adorkable: Basil gets adorably awkward several times when he's not being unfriendly. Notable moments include after how awkward and tongue-tied he gets after Olivia's My Parents Are Dead moment and the scene where he's awkwardly trying to cheer up Dawson. "I say...Dawson, old chap?" with a nervous smile.
  • Asexuality: He wasn't attracted by Missy Kitty's number and seems contemptuous of the concept of love. Its about as close to an outright asexual character Disney has ever made.
  • Badass Bookworm: What do you expect from somebody based on Sherlock Holmes?
  • Break the Haughty: After falling into Ratigan's trap:
    Basil: Oh, it's finally happened. I've been OUTWITTED!
  • Bunny-Ears Lawyer: Like Sherlock, he may be eccentric, but he solves the case.
  • Celibate Eccentric Genius: He's Exactly What It Says on the Tin, a brilliant Bunny-Ears Lawyer who apparently doesn't care about women. He was the only man at the bar who wasn't attracted to the sexy stripper Miss Kitty.
  • Cultured Badass: Being a Sherlock Holmes expy and an Omnidisciplinary Scientist, he shows skill in various areas such as science and history.
  • Deadpan Snarker: He has a good sarcastic humor.
  • Defrosting Ice King: Is pretty dismissive of Olivia and Dawson when first meeting them; eventually he warms up to the pair (even insisting that he does all his cases with Dawson).
  • Detective Animal: Naturally, he's a mouse. He currently provides the trope page image.
  • Disney Death: He falls from the clocktower, but manages to fly back up with a piece of Ratigan's contraption.
  • Distinguished Gentleman's Pipe: Sherlock Holmes is probably the Trope Codifier of this trope, and Basil is based on him.
  • Expy: A take-off of the classic Sherlock Holmes character.
  • Good Is Not Nice: Basil comes across as somewhat rude, especially early in the film, which makes him a good contrast to the Faux Affably Evil Ratigan. Fitting, since the original Holmes can be somewhat of a Jerkass Insufferable Genius himself at times.
  • Good Smoking, Evil Smoking: He smokes a pipe while Ratigan smokes a cigarette. And he switches to a cigarette for his "tough guy sailor" disguise.
  • Heroic B.S.O.D.: Basil undergoes a near-fatal one after he falls for Ratigan's trap.
  • Heterosexual Life-Partners: With Dawson.
  • Insufferable Genius: An undeniable genius but a bit egotistical and tactless, especially in his first scene. He gets better, thanks to Dawson and Olivia.
  • Jerk with a Heart of Gold: Moody, rude and self-centered but undeniably a good guy. He does slowly grow out of his rude Jerkass attitude, as seen when he tries to comfort Dawson. Granted, he doesn't actually apologise for his rant, but it's clear from the look on his face that he regrets being so harsh.
  • Large Ham: The incredibly expressive, hyperactive unless quite visibly depressed, always overdramatic Basil.
    "Young lady, you are most definitely not accompanying us! AND THAT IS FINAL !!!
  • Meaningful Name: Named for Basil Rathbone, the famous Sherlock Holmes actor.
  • Nice Hat: The iconic deerstalker.
  • Nice Mice: He may not be nice, but he's still good.
  • No Social Skills: He is downright rude towards Olivia and seems to be very very uncomfortable while trying to cheer up Dawson.
  • Not Distracted by the Sexy: Basil isn't the least bit distracted by Miss Kitty's burlesque performance. Lucky too, since he notices that his drink is being drugged.
  • Not Now, Kiddo: When Olivia and Dawson first meet him, he's too preoccupied with examining a bullet which might provide evidence to Ratigan's location to listen to what they're saying. And when they finally get his attention, he's less than interested in helping Olivia find her father...until he learns that Ratigan is involved.
  • Omnidisciplinary Scientist: Music, chemistry, physics, mathematics, botanics, zoology... He's a Sherlock Holmes expy, so this is a given. He's probably also the most intelligent Disney Hero until Milo Thatch.
  • Only One Name: Basil—notable because every other character has stated surnames. Most likely, Basil is his surname.
  • Protagonist Title: Basil is the "Great Mouse Detective".
  • Renaissance Man: Other than being a detective, he's skilled in many areas such as history, music, disguise, and being an Omnidisciplinary Scientist.
  • Rude Hero, Nice Sidekick: Basil, a Good Is Not Nice detective, has a tendency to be brusque and unconcerned with others (he has No Social Skills), while Dr. Dawson is an Adorkable Sensitive Guy who gets involved in the adventure to begin with because he can't stand to see a little girl cry. Given that this is a Sherlock Holmes story with mice, the dynamic between Basil and Dawson mirrors the one between Holmes and Watson. This being Disney, he (and Olivia) wind up defrosting Basil.
  • Running Gag: He constantly gets Olivia's surname wrong.
  • Sensitive Guy and Manly Man: The Manly Man to Dawson's Sensitive Guy.
  • Sesquipedalian Loquaciousness: Being the genius he is, Basil does this quite a bit, confusing or impressing Dawson at times.
  • Technobabble: Basil spouts some while analyzing Ratigan's Death Trap.
  • ˇThree Amigos!: Before Olivia gets kidnapped, he, Dawson, and Olivia certainly fit this trope while they're investigating the toyshop.
  • Tsundere: A minor Type A version. He starts out preoccupied, a bit detached from Dawson and Olivia, but they can bring out his sweeter, more empathetic side at times.

    Major Dr. David Q. Dawson
Voiced by: Val Bettin

Previously of the Queen's 66th Regiment in Afghanistan. His character is based upon Dr. John H. Watson from the Sherlock Holmes stories. The interaction between him and Basil mimics that of Watson and Holmes, as Dawson is constantly amazed by Basil's deductions. He eventually becomes Basil's associate, friend, and personal biographer.
  • Adorkable: Slightly clumsy and awkward, but very friendly.
  • Alliterative Name: David Q. Dawson.
  • Borrowed Catchphrase: Dawson says "You're despicable!" when he and Basil are tied up in a giant mouse trap by Ratigan.
  • Butt-Monkey: The movie's most frequent victim of comic mishaps and slapstick abuse.
  • Expy: Inspired by Sherlock Holmes's partner John Watson, most notably by Nigel Bruce's portrayal of the character.
  • Fat and Skinny: Fat to Basil's Skinny. They work as a duo.
  • Fat Best Friend: To Basil. Mainly a mix of type B (meek and awkward) and C (the bumbling type).
  • Heterosexual Life-Partners: With Basil. They become best friends over the course of the movie and still work together by the end.
  • The Lancer: Basil's sidekick and his total opposite. Mainly because Dawson is a polite Nice Guy while Basil is rude and arrogant.
  • Last-Name Basis: Never called by his first name, similar to Watson.
  • Most Definitely Not a Villain: When in disguised as a ruthless shipmate, is still as polite as ever. Basil can't help but groan every time he does this.
  • Nice Guy: He may not be the sharpest knife in the drawer, but Dawson is above all a decent and kindhearted person who would give you the shirt off his back if needed.
  • Nice Mice: Compared to Basil, Dawson is more polite and respectful.
  • No Celebrities Were Harmed: He's pretty clearly modeled on Nigel Bruce's portrayal of Watson.
  • Older Sidekick: Heavily hinted to be much older than Basil.
  • Sensitive Guy and Manly Man: The Sensitive Guy to Basil's Manly Man.
  • Sidekick: To Basil.
  • The Watson: He's an expy of Dr. John Watson, the Trope Namer.

    Olivia Flaversham
Voiced by: Susanne Pollatschek

A young female mouse of Scottish descent who seeks Basil's help in finding her toymaker father.

    Hiram Flaversham
Voiced by: Alan Young

Olivia's loving Scottish father. He works as a toymaker, and is kidnapped by Fidget to make the Queen Mousetoria robot for the evil Ratigan.
  • Brave Scot: Defiantly stands up to Ratigan and refuses to assist him with his scheme, even if it would cost him his life; he only relents when his daughter is threatened instead.
  • Distressed Dude: He is kidnapped by Fidget to create the clockwork Mouse Queen for Professor Ratigan.
  • Gadgeteer Genius: He is a toymaker, after all. It's why Ratigan went after him in the first place.
  • Good Parents: A very loving parent to Olivia.
  • Kidnapped Scientist: Flaversham is a toymaker, but he qualifies. His skill with making mechanical toys had applications for chicanery that Ratigan made forcible use of.
  • Last-Name Basis: Usually called by his last name.
  • Nerd Glasses: Has big eyeglasses, and he's a techno-savvy toymaker.
  • Nice Mice: Despite being a relatively minor character, he's undoubtedly a Nice Guy.
  • Parents in Distress: His kidnapping is what sets off the whole plot.
  • Reluctant Mad Scientist: Forced to use his talents for Ratigan's evil scheme so Ratigan won't hurt Olivia.

Voiced by: Frank Welker

Basil's trustful Basset Hound. He technically belongs to Sherlock Holmes, who lives above Basil.
  • Advertised Extra: During the time of the film's original release and re-release there were many reviews and articles questioning why "the big dog" was pushed so heavily in the advertising, despite his secondary role in the movie.
  • Big, Friendly Dog: The emphasis here is on big, since the main characters are mice.
  • The Big Guy: Much bigger than the other characters. While not sapient, he still helps Basil by carrying him around and following scent trails.
  • Canine Companion: He's the dog of Sherlock Holmes, but also a loyal friend to Basil.
  • Female Feline, Male Mutt: Male Mutt to Felicia's Female Feline, although they are enemies.
  • Friend to All Children: Quickly warms to Olivia - she has an easier time instructing him than Basil does, to his consternation.
  • Heroic Dog: He helps Basil solve cases.
  • Interspecies Friendship: He gets along quite well with Basil, and Basil's own companions for that matter.


    Professor (Padraic) Ratigan
Voiced by: Vincent Price (The Great Mouse Detective), Corey Burton (audiobook), Maurice LaMarche (House of Mouse)

Basil's archenemy. He is based on Professor Moriarty from the Sherlock Holmes stories. He plots to seize control of the British monarchy.
  • Adaptation Species Change: In the original Basil of Baker Street books he was a mouse. The film changed him into an actual rat, making the name more meaningful.
  • All There in the Script: His first name is Padraic. This makes sense, as—in various forms—it is one of the most common given names in Ireland, much like Moriarty is a common Irish surname. Furthermore, the name 'Padraic'note  means "noble man" or "of noble birth" and becoming nobility (or royalty) is Ratigan's goal.
    • ’Ratigan’ also rhymes with the Irish surname Madigan, and his defensiveness about being a rat neatly mirrors the way many Irish people who assimilated into Victorian Britain denied their roots, as the Irish were considered second class citizens.
  • Arch-Enemy: To Basil.
  • Ax-Crazy: Towards the climax, when he's enraged. Not that he was particularly sane to begin with.
  • Badass Cape: As you can see on his image.
  • Badass in a Nice Suit: Wears a suit like a Sharp-Dressed Man and he is a badass criminal who is also very strong.
  • Bad Boss: He's generally affable towards his minions, but when one of his flunkies gets drunk and calls him a rat, he promptly feeds said minion to the cat, and threatens to do the same to his other minions unless they continue with his Villain Song.
  • Berserk Button: He despises being called a rat, even though he technically is one.
  • Big Bad: He's based off of Professor Moriarty, after all.
  • Boomerang Bigot: He hates rats despite being one himself and tries to pass for a "big mouse."
  • Bond Villain Stupidity: Justified. He explains that he did plan on staying and watching as his latest Death Trap did its work, but since Basil and co. showed up 15 minutes later than he planned, he doesn't have time to stay, and so he rigs a camera to capture Basil's dying moment instead.
  • Burn the Orphanage: "Worse than the widows and orphans you drowned?"
  • Cape Snag: Basil invokes this on Ratigan towards the climax.
  • Captain Ersatz: Professor Moriarty.
  • Card-Carrying Villain: Interestingly enough, his minions enjoy working for him because of this. And of course, he's also voiced by Vincent Price.
  • Child Hater: He's drowned an unspecified number of orphans, planned to eliminate orphans after becoming a king, and he's not nice towards Olivia. At all.
  • Complexity Addiction: He couldn't decide on a single way to kill Basil, so he opted instead to make a Rube Goldberg Device that used deadly instruments like a mousetrap, a gun, a crossbow, an axe, and an anvil all at the same time.
  • Diabolical Mastermind: Defined by Basil as the "Napoleon of crime" (an obvious reference to Professor James Moriarty).
  • Disney Villain Death: His Karmic Death.
  • The Dreaded: Ratigan is the most hated being in the Mousedom, because he's such a vile, cruel monster, and once he comes out in front of the other citizens, he's met with contempt and disgust immediately. However, he's well aware everyone hates him, so by replacing the queen and have her grant him full control, his subjects won't have any choice but to serve him or die.
  • Even Evil Has Loved Ones: He seems to care for Felicia, his Right-Hand Cat.
  • Evil Brit: Albeit with the American voice of Vincent Price.
  • Evil Counterpart: To Basil.
  • Evil Feels Good: "Oh, I love it when I'm nasty"
  • Evil Genius: As to be expected due to being Basil's archenemy.
  • Evil Is Bigger: Far larger than anyone else in the cast, to the point the muscles in his arm alone are bigger around than Basil's waist! This is because he is a rat.
  • Evil Is Hammy: Look at who voiced him. It's inevitable.
  • Expy: Ratigan is the Evil Counterpart to Basil, just as Moriarty is to Holmes.
  • Famous Last Words: Ratigan says "I've won!" just before Basil distracts him with his handheld bell. Then, he hears the sound of Big Ben tolling and ends up falling to his Disney Villain Death
  • Fangs Are Evil: He has a mouth full of noticeably jagged and yellowed teeth.
  • Faux Affably Evil: He comes off as rather cheerful and pleasant, especially when compared to Basil (who can be a bit of a smug Jerk Ass). However, he's also an evil criminal genius who's perfectly willing to threaten a child in order to get what he wants.
  • For the Evulz: He loves being a cruel, rotten villain, and often boasts about it.
  • Genius Bruiser: He's an evil genius...but is also strong enough to lift up Hiram with one finger and trounce Basil in a one-on-one fight.
  • Good Smoking, Evil Smoking: Ratigan smokes a cigarette (complete with long stemmed filter), while his Arch-Enemy Basil smokes a pipe.
  • I Am Not Weasel: He HATES being called a rat.
  • Insistent Terminology: He's a "big mouse." Which, amusingly enough, was what he was in the books.
  • Karmic Death: Just as Ratigan used a handheld bell to execute his incompetent followers, he dies when the bell from Big Ben tolls.
  • Kick the Dog: When he breaks the toy Hiram made for Olivia. And later kicks Olivia herself.
  • Kick the Son of a Bitch: Ratigan throws Fidget off his ship after he asks if he can toss Olivia overboard.
  • The Kingslayer: Attempted regicide on Queen Mousetoria to take over the Mouse World equivalent of the British Empire.
  • Large and in Charge: He's significantly larger than his mooks.
  • Large Ham: He's voiced by Vincent Price, and is actually even hammier than most of his other characters. Also probably the hammiest of all Disney characters.
  • Last-Name Basis : He's only known as Ratigan, the original book series reveals that his first name is Padraic.
  • Laughably Evil: It also helps that he's voiced by a man who plays laughably evil characters.
  • A Lizard Named "Liz": Despite what he claims, he is a rat named Ratigan.
  • Muscles Are Meaningful: He's one of the biggest and most muscled characters in the film that isn't a dog or cat, and he utterly dominates Basil during their brief wrestle near the end of the film, only losing thanks to Basil outwitting him.
  • Narcissist: Perhaps one of the best examples in Disney canon, down the over-the-top melodramatics.
  • Near Villain Victory: Basil may have foiled Ratigan's plans, but Ratigan very nearly puts down the determined detective in a No-Holds-Barred Beatdown atop Big Ben. Ratigan surely would've triumphed if not for a stroke of dumb luck on Basil's part.
  • Nice Hat: Like Basil, he wears a hat, although in his case he wears a top hat.
  • No-Holds-Barred Beatdown: Towards the end of the movie, Ratigan mercilessly attacks Basil while shouting "There's no escape this time, Basil!" That Ratigan is usually more friendly than that only makes his suddenly vicious attack feel even more intense. Memorable enough to provide the page image for a while.
  • Nothing Personal: Downplayed. He barely acknowledges Dawson when the latter is tied to the trap with Basil, though as he leaves he gives Dawson an offhanded apology while telling him that he shouldn't have gotten involved with Basil.
  • Offstage Villainy: "From the brain that brought you the Big Ben Caper ... and wondrous things like the Tower Bridge Job..." And the widows and orphans he drowned.
  • One-Winged Angel: In the ending, he reverts to his monstrous feral rat form and comes within a hair's breadth of killing Basil.
  • Out-Gambitted: "Poor Basil — oh, he is in for a little surprise..."
  • Perma-Stubble: Although technically speaking it's just the fur color.
  • Polite Villains, Rude Heroes: Despite being a vicious Diabolical Mastermind who is perfectly willing to threaten children to get his way, Ratigan puts up an act of being a cheerful, pleasant gentleman, in stark contrast to his nemesis Basil, who has No Social Skills and often comes across as a rude, smug Jerkass.
  • Punny Name: Ratigan.
  • Right-Hand Cat: Felicia, who he interestingly seems to care about.
  • Sadist: By his own admission, he takes pleasure in being evil. His exposition song mentions he drowned widows and orphans For the Evulz.
  • Shame If Something Happened: He uses this to threaten Flaversham's daughter Olivia if Flaversham doesn't help him with his evil scheme.
    Professor Ratigan: (activating Olivia's wind-up ballerina doll and watching it dance) I would spend many a sleepless night if anything were to befall her. (proceeds to pick up the doll and viciously squeeze it until it breaks)

    Fidget the Bat
"Ow! My only foot!"
Voiced by: Candy Candido

Ratigan's bumbling bat henchman. He tends to do the dirty work for his boss. He has a crippled wing and a peg leg, and, as a result, he cannot fly.
  • Adorable Evil Minion: Beside his violent evil nature, Disney meant for him to be both loveable and scary.
  • Bag of Kidnapping: Does this to Olivia.
  • Bat Out of Hell: He's a bat, and he's one of Ratigan's henchmen. He has some genuinely scary moments, like the Nightmare Face he makes when he breaks into Hiram's workshop and kidnaps him.
  • Beware the Silly Ones: Fidget might provide most of the films comic relief, but he can be downright brutal when he wants to be. As a variation of the usual trope, he's shown to be scary and brutal in his first scene (played very seriously) while his silly and comical traits are visible later.
  • Bumbling Sidekick: Subverted quite brutally. He can be a bit clumsy when off-duty and he does provide a few good bits of humor, but is very competent and can be downright terrifying when he needs to be.
  • Butt-Monkey: Ratigan has a tendency to treat Fidget this way.
  • Distracted by the Sexy: Gets his pegleg stuck in a floorboard when he's too busy watching Miss Kitty's burlesque act.
  • The Dragon: He's Ratigan's right-hand-bat.
  • Evil Cripple: A peg-leg and a crippled wing so he can't fly, and a rather nasty character to boot.
  • Evil Sounds Raspy: A rather extreme example.
  • Handicapped Badass: He has a peg leg, and a "broken" (mishealed? misshaped?) wing. Yet, he is a competent fighter.
  • Hidden Depths: Despite his faults, Fidget had been shown various times to be quite competent. There's also the start of the movie...
  • Indy Ploy: The chase scene with Basil in the toy store demonstrates this quite well. Fidget really knows how to think on his feet(even if he only has one foot).
  • Not-So-Harmless Villain: Don't be fooled by his occasional bumbling and physical limits, he's far from harmless. The scene where he brutally beats up and kidnaps Hiram best demonstrates just how frighting and dangerous Fidget really is.
  • Scary Teeth: Which he uses occasionally during his ambushes.
  • Shadow Discretion Shot: The scene of Fidget and Hiram's fight was so brutal, that Disney made it censored by shadows. It can be also noted that Hiram's toyshop was left in chaos after the fight.
  • Violence Is Disturbing: In the scene where Fidget kidnaps Hiram. Along with the climactic fight between Basil and Ratigan, this is one of the most brutal and frightening scenes of the whole movie.
  • Vague Age: Olivia refers to him as "old", but he is small, somewhat cute and has a high-pitched voice; in one of the spin-off comics, post-Heel–Face Turn, he was implied to be a teenager just a handful of years older than Olivia, if you can believe that.
  • Would Hurt a Child: Perfectly willing to throw Olivia out of Ratigan's blimp to "lighten the load". It didn't work out as he had hoped.
  • You Have Failed Me: When he tires from pedaling the blimp's propellor, he suggests lightening the blimp, Ratigan does so... by throwing him off of it.

Voiced by: Frank Welker

Ratigan's massive and pompous pet cat. Ratigan calls upon her by ringing a special bell to dispose of traitors or anyone who makes him angry.

Other Characters

    Miss Kitty
Voiced by: Melissa Manchester

A female dancer/showgirl mouse who briefly appears in the movie.
  • All There in the Script: Miss Kitty's name isn't brought up anywhere in the film, but it can be seen on her character model sheet. Although it isn't likely to be her actual name, but a descriptor.
  • Bad Girl Song: "Let Me Be Good to You".
  • The Chanteuse: During the bar scene.
  • Chorus Girls: Miss Kitty's musical number also has two backup dancers that dance alongside her. They are her twin-sisters, each with a Beauty Mark.
  • Hello, Nurse!: When Miss Kitty start to strip, in her musical number, only Basil pays no attention while patrons grab fruitlessly at her.
  • Ms. Fanservice: Her only appearance in the film is her putting on a burlesque performance while stripping from a dress to a showgirl outfit, earning quite a bit of cheers from the bar patrons.
  • Parent Service: Her role in the movie.
  • She's Got Legs: She has some of the most shapely, curvaceous legs ever animated.
  • True Blue Femininity: Her showgirl outfit, as seen in the picture above. Her backup dancers wear pink though.
  • Vocal Dissonance: Her singing seems this way at first: she's a cute, innocent-looking white mouse girl in a Victorian skirt and shawl, with the sultry alto voice of Melissa Manchester. But then she does her striptease and the dissonance is no more.
