[[folder: Oliver]]
->'''Voiced by:''' Joey Lawrence
* BadassAdorable: With the emphasis on "adorable."
-->'''Fagin:''' That reminds me, I saw Desoto's nose; who did that?
-->(Dodger presents Oliver to Fagin)
-->'''Fagin:''' You... you? *Laughs* That took a lot of guts! We have never had a cat in the gang before... we can use all the help we can get.
* CuteKitten
* {{Determinator}}
* HappilyAdopted: By LonelyRichKid Jenny, later in the film.
* HeartwarmingOrphan: Initially he was a nameless, unwanted CuteKitten left alone in a box.
* TheHero: As the title of the film would suggest.

* NaiveNewcomer: To Fagin's gang.
* OrphansOrdeal
* ProtagonistTitle: And Company.
* RedHeadedHero
* RidiculouslyCuteCritter: Yes. [[TheWoobie So very much.]]

[[folder: Dodger]]

* TheArtfulDodger: An {{expy}} of the TropeNamer.
* BigBrotherInstinct: After CharacterDevelopment, he shows this towards Oliver.

* StreetSmart

[[folder: Ignacio Alonzo Julio Federico de Tito]]
->'''Voiced by:''' Cheech Marin
* AbhorrentAdmirer: To Georgette. At least at first.
* GoodSmokingEvilSmoking: At Jenny's apartment, he sniffs a cigar lying around, quoting, "[[Creator/CheechAndChong If this is torture, chain me to the wall]]!!!"
* TheLancer
* LatinLover: Averted until the end of the movie.
* MotorMouth
* TheNapoleon
* OverlyLongName: His friends simply call him "Tito" [[CaptainObvious for a reason]].
* VitriolicBestBuds: With Francis.

[[folder: Einstein]]
->'''Voiced by:''' Richard Mulligan
* BigFriendlyDog
* TheBigGuy
* DogsAreDumb
* DumbMuscle
* IronicNickname: Yeah, he ain't exactly the smartest member of Fagin's gang.

[[folder: Francis]]
->'''Voiced by:''' Roscoe Lee Browne
* DeadpanSnarker
* InsistentTerminology: He refuses to be referred to as "Frank" or "Frankie", a fact that Tito abuses when they fight over what to watch on TV.
* LargeHam
* MeaningfulName: Some denominations of Christianity revere Francis of Assisi, who was born into wealth, as the patron saint of animals. Many churches conduct animal blessings on his feast day.
* SmallNameBigEgo: He fancies himself as a Shakespearian actor material and high class, despite being another homeless mutt.
* TheSmartGuy
* VitriolicBestBuds: With Tito.
* WoundedGazelleGambit: Plays dead in front of Jenny's limo to distract Winston long enough for Oliver and Tito to steal the radio from inside.

[[folder: Rita]]
->'''Voiced by:''' Sheryl Lee Ralph
* TheChick
* OnlySaneWoman: The most level-headed dog in Fagin's gang, probably because WomenAreWiser.
* SassyBlackWoman
* TheSmurfettePrinciple: Is noticeably the only female dog in Fagin's gang, and the ''only'' major female character, apart from Jenny and Georgette.
* TertiarySexualCharacteristics: She seems to be wearing blue eyeshadow. What's odd is, Rita is never seen applying it whereas it's a part of Georgette's morning routine.
* WomenAreWiser: Notably the only one who voices doubts about [[spoiler:"rescuing" Oliver from Jenny's house]], as well as the only one who notices that [[spoiler:Oliver is unhappy afterwards]].

[[folder: Fagin]]
->'''Voiced by:''' Creator/DomDeLuise
* AdaptationalHeroism: His [[Literature/OliverTwist book counterpart]] wasn't a sympathetic character.
* AntiVillain: He does thievery and has the dogs do his dirty work, but he does care for them. Plus he's justified in his paranoia his dealings with Sykes and the welfare of the dogs if he gets "sleepin' with the fishes".
* CowardlyLion: He does crimes to escape his possible gangster death punishment from Sykes, but he does try to fight against him once he goes too far.
* TheFagin: An {{expy}} of the TropeNamer only having a heart of gold this time around.
* HomelessPigeonPerson: Except with dogs.
* JerkWithAHeartOfGold: A difference shared with the film adaptation - yes, he's a thief, and was planning to ransom Oliver, but he clearly loves his pets, and when he learns that Jenny is Oliver's owner, he immediately gives up all idea of collecting the ransom (even though he is fully aware that ''he will be killed'' if he fails to pay Sykes) in order to return Oliver to her.
* SparedByTheAdaptation: [[spoiler: His [[Literature/OliverTwist book counterpart]] is sentenced to execution at the novel's end.]]

[[folder: Roscoe and Desoto]]
->'''Voiced by:''' Taurean Blacque (Roscoe) and Carl Weintraub (Desoto)
* AbhorrentAdmirer: Rita is plainly repulsed by Roscoe's advances.
* ColorCodedCharacters: Roscoe = red, Desoto = blue.
* DarkIsEvil: Is it ever!
* EvilHasABadSenseOfHumor: Hinted at with Roscoe.
* {{Expy}}: Somewhat like the alligators, Brutus and Nero, from ''Disney/TheRescuers'', since there are two of them, and both serve the villain, but are much more witty and sinister.
* FamilyUnfriendlyDeath: [[ShockAndAwe Fried by the third rail.]]
* NoHoldsBarredBeatdown: Anytime they get into a fight with Dodger.
* RedOniBlueOni: Inverted, since Roscoe, the red-collared doberman, is somewhat cooler than the blue-collared doberman, Desoto.
* ScaryBlackMan: Roscoe - you can hear his African - American accent.
* ThoseTwoBadGuys
* VileVillainSaccharineShow: While the main dogs can scare off the rabid dogs that showed up in the opening song, they face these two with disgust. Besides being dogs for a gangster affiliate, Desoto is implied to be a kitten killer, even more disturbing implications is that they're both human killers, as [[EvilHasABadSenseOfHumor Sykes makes a cruel joke to her that they should eat Jenny if her parents didn't pay the ransom]].

[[folder: Bill Sykes]]
->'''Voiced by:''' Robert Loggia
* AxCrazy: At one point.
* BadassFingersnap: Its his attack dogs' cue to attack.
* BadBoss: To Fagin and possibly to any gang affiliates.
* BigBad: Though he's more of a threat to Fagin rather than Oliver.
* DangerouslyGenreSavvy: When he sees the "Pizza Delivery Boy" (actually Francis and the gang) at his door, he immediately arms himself with a pistol, realizing that the person was not likely to be a pizza delivery person as he doesn't remember ever ordering a pizza that day.
* DarkIsEvil: Indeed. He's usually shown in shadows like most stereotypical villains.
* FatBastard: Very large, very intimidating, and very much a despicable excuse for a human being.
* FauxAffablyEvil: Has his moments.
* FourEyesZeroSoul
* GoodSmokingEvilSmoking: Evil smoking, naturally.
* GutturalGrowler
* FamilyUnfriendlyDeath: [[spoiler: Ultimately hit by a subway train in the end.]]
* LoanShark: His job is this, and he'll get money no matter what the cost.
* ObviouslyEvil: Look at him. He's just as evil as he seems.
* RightHandAttackDog: Two for the price of one! (See above.)
* SecondFaceSmoke: Does this to Fagin while holding him in a NeckLift through his car window.
* SoftSpokenSadist: He's clearly a horrible human being underneath his businessman fašade.
* VillainousBreakdown: While he's mainly calm throughout the movie, in the climactic car chase, he pulls down the gear stick so hard it ''breaks off'' and ''punches his hand through his car's window'' to get at Jenny.
* VileVillainSaccharineShow: Especially for Disney. Sykes has no sorcery, [[LargeHam hamminess]] or even a VillainSong; he is a cold-blooded LoanShark played straight. His methods are brutal as he holds Jenny for ransom, has Fagin in a loan deal with the implications of mafia execution and, in one scene where he's on the phone, he's clearly instructing the person on the other end how to perform the CementShoes method.

[[folder: Jenny Foxworth]]
->'''Voiced by:''' Natalie Gregory
* TheCutie: A SpoiledSweet little girl, and very cute as well.
* DamselInDistress: In the climax after [[spoiler: she is abducted by Sykes.]]
* DitchTheBodyguards: Being seven years old, she had to elude Winston in order to save Oliver.

* NiceGirl: Jenny is very caring and friendly.
* RedheadedHero
* SpoiledSweet: To a certain extent.

[[folder: Winston]]
->'''Voiced by:''' William Glover
* CoolOldGuy: He's apparently a fan of pro wrestling.
* DeadpanSnarker
* JerkWithAHeartOfGold: Sure, he's a bit of a snob but it's clear he does care about Jenny, and he eventually warms to Fagin and his gang too.
* RollingPinOfDoom: Uses it as an ImprovisedWeapon when he goes to inspect the noise coming from Georgette's room.

[[folder: Georgette]]
->'''Voiced by:''' Bette Midler
* AntiHero: She is extremely jealous of Oliver when Jenny first gets him, and tries to get rid of him after that. Despite this, she ''does'' help Oliver and the gang [[spoiler: rescue Jenny from Sykes's clutches]] and appears to have...''slightly'' lightened up by the end.
* ArentYouGoingToRavishMe: When it becomes clear Dodger didn't break into her room for sex.
* AttentionWhore: She is used to a lot of attention and can't handle Jenny giving any of hers to Oliver.
* BeautyIsNeverTarnished: Averted. She's usually groomed and pretty, but in certain situations she looks worse for wear.
* CoolBigSis: Consigns herself to being this for Oliver in the end, though the "cool" part is debatable.
* DramaQueen: She freaks out over the tiniest things.
* DudeMagnet
* GreenEyedMonster: Towards Oliver for much of the movie.
* EveryGirlIsCuterWithHairDecs: She always wears a pink bow at the back of her head.
* HelloNurse: Most male dogs absolutely love her.
* IBrokeANail
* InformedAttractiveness: She's not too different in design to Rita, but is implied to be an unrivaled beauty.
* ItsAllAboutMe: She gets a little better though.
* JerkWithAHeartOfGold: Although she starts off as a straight-up {{Jerkass}}, she eventually regrets her actions and comes to accept Oliver as her family.
* LargeHam: Nearly every line is a slice of pure pork, as you would expect from her voice actress.
* LovableAlphaBitch: She does have a heart, especially towards the end.
* ThePrimadonna: Is something of a celebrity in dog show circles, and isn't shy about mentioning it.
* ReallyGetsAround: Just check out her shrine to her admirers! Even [[Disney/TheGreatMouseDetective Rat]][[InterspeciesRomance igan]] appears in there.
* RichBitch: A ''literal'' example!
* ShrineToSelf: Her room is not only stuffed with photographs and paintings of her and many, MANY mirrors, but statues of her make up most of her bed, flank her vanity table, and her dog bowl has a few miniature Georgettes on it.
* YouGottaHaveBlueHair: It is unclear whether her fur was dyed blue, [[AmazingTechnicolorWildlife naturally blue]], or intended as gray via HairColorDissonance.
