Here is a listing of the characters featured in the Creator/WarnerBros series ''WesternAnimation/TinyToonAdventures''.

[[folder: Buster Bunny]]
!Buster Bunny

--> ''WesternAnimation/LooneyTunes'' counterpart: WesternAnimation/BugsBunny (specifically the calm, cool and level-headed part of his personality).
--> Voiced by: Creator/CharlieAdler until the end of Season 3 and the TV specials, when John Kassir replaced him. (English). Creator/RyuseiNakao (Japanese), Marcelo Rodriguez (Latin American Spanish), Luq Hamet (French)

The male cohost of the show, a blue-furred male bunny. Effectively TheEveryman of the show, being that he is generally portrayed as the smartest, most sensible and levelheaded of the protagonists, although not to the extent he's incapable of doing wacky stuff himself. Not related to Babs Bunny, but the two of them are occasionally hinted as being either a couple or attracted to each other.

* TheAce: He is good at various sports, and has also shown incredible musical skill in playing the drums and the electric guitar.
* AlliterativeName: His first and last names begin with B.
* BadassAdorable: A younger and cuter version of WesternAnimation/BugsBunny.
* BlueIsHeroic: He has light blue fur, and is TheLeader and the StraightMan to some of his more wacky friends.
* CatchPhrase:
** "Now, ItsPersonal."
** And "Now it's time to party: Buster style!"
* DeadpanSnarker: He has the sassiness of Bugs Bunny, but has to work a little harder because he's younger and still learning.
* FourTemperamentEnsemble: The Phlegmatic
* FriendToAllChildren: Aside from getting even with the antagonists, Buster also helps out kids who have been or may be victimized by them, such as saving a bunch of kids from being bored to death by an arrogant childrens' entertainer, and exposing a con-artist bike seller who sells shoddy bikes to kids. He even once interrupts a segment to warn kids NOT to try what Elmyra had just done (telling her dad to suddenly stop the car in the middle of a busy road and running out in traffic).
--> '''Buster:''' Hi kids! I just have one thing to say. Please, please PLEASE don't ever ever EVER get out of a car and cross a busy highway or street!
* HalfDressedCartoonAnimal: Ironically, in the first episode, he asks for clothes to please the censors, and yet still doesn't wear pants. This gets [[LampshadeHanging lampshaded]] several times.
* TheHero: Buster's adventures include outsmarting Montana Max numerous times, escaping from Elmyra's house, spending a summer vacation downriver, facing a Wolverine, trying to get muscular, saving defenseless animals, playing with a virtual reality machine, discovering lost treasure, going to the prom with Babs, visiting the center of the Earth, and directing a Christmas special.
* NiceGuy: Buster is generally a nice guy, until provoked, that is.
* NiceMeanAndInbetween: The In-Between to Hamton's Nice and Plucky's Mean. While he can be level-headed, he still has his [[RascallyRabbit trickster side]], much like Bugs Bunny.
* OnlySaneMan: Particularly evident whenever he's trying to direct a production with the other characters, which nearly drives him up the walls.
* PinkGirlBlueBoy: Blue Boy to Babs' Pink Girl (both literally, because of their fur color, and figuratively because of their personalities).
* ThePrankster: He has a mischievous nature, though his pranks are usually geared towards bullies and villains. Occasionally, however, he will play pranks on his on friends, sometimes on Babs, who usually responds in equal fashion.
* RascallyRabbit: Buster and Babs Bunny take after Bugs in this fashion.
* RedOniBlueOni: The Blue to Babs' Red.
* RidiculousProcrastinator: While he usually averts it (and even helps Plucky when the latter did the same on a few occasions), he plays this straight in "Buster's Guide to Goofing Off" (part of "You Asked For It Again"), wherein he goofs of on his science project that he had two months to complete until the last possible minute, and teaches the viewers to do the same.
* RunningGag: He and Babs clarifying that they're not related, despite the same last name.
* SavvyGuyEnergeticGirl: Savvy Guy to Babs' Energetic Girl.
* ShipTease: Buster has many times shown to be attracted to Babs, as the feeling is usually mutual. Sometimes Buster will nervously retreat from her advances, sometimes he returns her affection, and sometimes he even goes out of his way to impress her.
* SpeciesSurname: A bunny with the surname Bunny.
* SuperSpeed: He has this ability in several of the video games, such as ''[[VideoGame/TinyToonAdventuresBustersHiddenTreasure Buster's Hidden Treasure]]'', ''[[VideoGame/TinyToonAdventuresBusterBustsLoose Buster Busts Loose]]'', and ''Tiny Toon Adventures 2: Montana's Movie Madness''.
* TenMinuteRetirement: In "It's a Wonderful Cartoon Show", Buster, in a state of self-loathing, decided that perhaps the series would be better off without him. He's stopped by the White Rabbit who shows him exactly what the series would've been like if he were never on, and it wasn't pretty.
* TrademarkFavoriteFood: Carrots, much like Bugs Bunny.
* {{Trickster}}: Much like Bugs Bunny.

[[folder: Babs Bunny]]
!Barbara Ann "Babs" Bunny

--> ''WesternAnimation/LooneyTunes'' counterparts: WesternAnimation/BugsBunny (specifically the Bugs Bunny that dresses in drag to trick his enemies, and represents the manic and zany part of his personality), and Honey from the [[ Bosko cartoons.]] (See "The Original Looney Tunes" below and the episode "Fields of Honey")
-->Voiced by: Creator/TressMacNeille (English), Creator/MinaTominaga (Japanese), Elena Prieto (Latin American Spanish), Barbara Tissier (French)

The female cohost of the show, a pink-furred bunny. In contrast to Buster, she's more manic and wacky, though still capable of getting serious and sneaky if she thinks she needs it. Despite having the last name, as they constantly reiterate, they're not siblings, though many episodes do imply some level of attraction between them.

Note that both Babs and Buster apply the PinkGirlBlueBoy trope directly. A possible inspiration for a character introduced a couple years later, [[Film/SpaceJam Lola Bunny.]]

* AlliterativeName: B is the first letter of her first and last names.
* BadassAdorable: A younger and cuter female version of WesternAnimation/BugsBunny.
* BarefootCartoonAnimal: "Don't I have the cutest toes?"
* BerserkButton: Being called "Barbara Ann Bunny".
* CatchPhrase:
** "Who knew?" (always said the exact same way)
** "I just can't help myself!"
* ChangingClothesIsAFreeAction: She is capable of quick costume changes, often achieved by simply spinning around in a circle very fast.
* DoNotCallMePaul: Never ever call her by [[EmbarrassingFirstName her real name, Barbara Ann Bunny.]]
* EarsAsHair: "Do you like my ears better up or down?" .
* FourTemperamentEnsemble: The Sanguine.
* GenkiGirl: She is cheerful, hyperactive, lovable and irrepressible ham. Babs is a high energy impressionist and comedienne who doesn't know when to quit.
* HairDecorations: Her ear ribbons.
* HypocriticalHumor: In the "Respect" music video for "Tiny Toon Music Television", she sings the titular song whilst doing all kinds of disrespectful things, like skating through a library whilst loudly singing and disrupting both a trial and ''a funeral for a kid's pet''.
* IrritationIsTheSincerestFormOfFlattery: An early sketch ("Born To Be Riled", in "The Buster Bunny Bunch") revolves around her friends becoming offended by her accurate-but-unflattering impressions of them, and paying her back by doing similar impressions of her.
* JerkWithAHeartOfGold: Her impressions can come off as insensitive at times, but she genuinely means no harm by them.
* LittleMissSnarker: Like Buster, she's sassy, but with a distinctly feminine flair.
* MassiveNumberedSiblings: Being a rabbit, she has dozens of younger brothers and sisters, only one of whom has his name revealed (Mortimer).
* NiceMeanAndInbetween: The Mean to Fifi's Nice and Shirley's In-Between. She is often sassy and insensitive towards her friends, usually without meaning to be.
* OnlyKnownByTheirNickname: Which is how she prefers it.
* PinkGirlBlueBoy: Pink Girl to Buster's Blue Boy.
* PinkMeansFeminine: She's a girl and she has pink fur.
* ThePrankster: A funny bunny who will do nearly anything for a laugh.
* RascallyRabbit: Buster and Babs Bunny take after Bugs in this fashion.
* RedOniBlueOni: The Red to Buster's Blue.
* SavvyGuyEnergeticGirl: Energetic Girl to Buster's Savvy Guy.
* ShipTease: Babs is many times shown to have a crush on Buster Bunny. Sometimes Buster will nervously retreat from her advances, sometimes he returns her affection, and sometimes he even goes out of his way to impress her.
* SlapstickKnowsNoGender: Both the male and female characters get their share of slapstick comedy. Although Babs is rarely on the receiving end, sometimes [[ it happens.]]
* SpeciesSurname: In spite of her and Buster having the same surname, the two of them always state "[[LampshadeHanging No relation]]" after introducing themselves.
* TrademarkFavoriteFood: Carrots, much like Bugs Bunny.
* {{Trickster}}: Both she and Buster inherit this from their mentor Bugs Bunny, but especially Babs.

[[folder: Plucky Duck]]
!Plucky Duck

--> ''WesternAnimation/LooneyTunes'' counterpart: WesternAnimation/DaffyDuck (specifically the sarcastic, egotistical, attention-seeking Daffy of later cartoons).
--> Voiced by: Creator/JoeAlaskey (English), Creator/KoichiYamadera (Japanese), Juan Carlos Vazquez (Latin American Spanish/1st voice), Orlando Noguera (Latin American Spanish/2nd voice), Luq Hamet (French)

A green-feathered, arrogant, narcissistic, bungling young drake, Plucky wants to be the metaphorical leader of the pack, but his arrogance far outsides his competence. Though he craves attention, he rarely gets, at least not for the things he wants to get it for.

* AntiHero: He's one of the main characters, but is often self-centered.
* AttentionWhore: Moreso than his mentor, Daffy Duck.
* ButtMonkey: Although it's played for comedy, Plucky's bad luck and frequent physical abuse can make him something of a pitiful figure. Even when he's not being a jerk, he still tends to come off badly -- like in his appearance in "Tiny Toon Music Television", where not only does the caliph's cute daughter turn out to be Elmyra, but ''she'' breaks the jade duck statuette he retrieved and ''he'' gets punished by being forced to serve as a stand-in for it.
* TheChewToy: Prone to getting hit by an AnvilOnHead and many other outright abuses. The amount of constant pain, bad luck and wince-worthy situations that get inflicted on him rival Daffy Duck and it's made all the worse when you consider its a child getting run over by cars, beaten by professional boxers, and crushed under 700lb pigs and sumo wrestlers.
* CrouchingMoronHiddenBadass: When he gets a chance to shine, he REALLY shines, especially when crossing blades with Montana Max.
* DeadpanSnarker: Even more than ''Babs!''
* FourTemperamentEnsemble: The Choleric.
* HalfDressedCartoonAnimal: He wears a white tank top, but no pants.
* HeelFaceRevolvingDoor:
** In the episode, "Citizen Max", Monty pays Plucky to help him win the school election against Buster. After Buster was wrongfully expelled from Acme Looniversity, Plucky later poses as "Deep Quack" to prove to Buster and Babs that Monty framed the former for cheating and helps them expose Monty for the fraud that he is.
** In the ''[[VideoGame/TinyToonAdventuresBustersHiddenTreasure Buster's Hidden Treasure]]'' video game, Plucky is fought twice; the first time as his normal BrainwashedAndCrazy self, then later as his superhero alter-ego, the Toxic Revenger, denying his true identity. Buster manages to snap him out of it by threatening not to help him with future homeworks.
* InterspeciesRomance: With Shirley the Loon. In "The Return of Pluck Twacey", he also swoons over [[FemmeFatale Hata Mari]], [[MythologyGag the pigeon from "Plane Daffy"]], whilst in the "Istanbul (Not Constantinople)" music video from "Tiny Toon Music Television", he's shown swooning over the caliph's cute (human) daughter.
* {{Jerkass}}: Just like the post-{{Flanderization}} Daffy Duck, Plucky is an egotistical prick who cares little about the others.
* JerkWithAHeartOfGold: He has a few PetTheDog moments, but those depend on the episode.
* JerkWithAHeartOfJerk: In the ChristmasEpisode, he prays for Buster to get better after claiming to not care about him, but it's only because Plucky doesn't want Buster's departure to end the show and leave him having to find work elsewhere.
* TheLancer: He tends to play second fiddle to Buster.
* {{Narcissist}}: In the first episode, he proves that he can play a lover by delivering a romantic overture to a hand mirror.
* NiceMeanAndInbetween: The Mean to Hamton's Nice and Buster's In-Between. He acts as the narcissistic AttentionWhore.
* OnlySaneMan: Acts as this to Hamton's family in the ''How I Spent My Vacation'' film.
* PluckyComicRelief: Bonus points for being actually named "Plucky". It says something that he still manages to be recognizable as this despite every character technically being a comic character.
* RidiculousProcrastinator: He has procrastinated on his homework many times, and has a different solution for each time he procrastinated on his homework, whether it be building a TimeMachine, getting Buster to teach him the basics of animation, PlayingSick, [[FileMixUp switching his test with Egghead Jr.'s]], or pausing a dog and cat fight and trying to pass it off as a painting.
* SensitiveGuyAndManlyMan: Manly Man to Hamton's Sensitive Guy.
* {{Sidekick}}: Hired as such to Buster and Babs, much to his humiliation.
* SmallNameBigEgo: Like Daffy in his post-ScrewySquirrel appearances, his arrogance despite his obviously inferior talents is one of his most defining personality traits.
* SpeciesSurname: He's a duck and his last name is Duck.
* SpinoffBabies: His baby-self starred in a few shorts, and became somewhat of an EnsembleDarkHorse in the memories of fans, to the point that he even cameoed a couple times in ''Animaniacs''.
* ThrowTheDogABone: He gets repeatedly hit with anvils in "Ducklahoma" as payback for trashing Buster's original production and demanding a showcase. After getting repeatedly hit during his musical numbers, Plucky apologizes and begs for some relief--saying there must be someone else on this show more deserving of this treatment than him. So, Buster cues Elmyra's song.
* ToothyBird: He has teeth.
* WithFriendsLikeThese: He's sold out his friend, Hamton, on several occasions.

[[folder: Hamton J. Pig]]
!Hamton J. Pig

-->''WesternAnimation/LooneyTunes'' counterpart: Porky Pig.
-->Voiced by: Creator/DonMessick (1990-1995), Billy West (''Toonenstein: Dare to Scare!'' and ''Defenders of the Universe'' video games) (English), You Yoshimura (Japanese/1st voice), Shunichi Sugawara (Japanese/2nd voice), Jose Gomez (Latin American Spanish/1st voice), Juan Guzman (Latin American Spanish/2nd voice), Patrick Guillemin (French)

A somewhat milquetoast young pig, Hamton is the unabashed Straight Man of the protagonists; not wacky himself, but capable of generating laughs by playing foil to the more weird and manic outbursts of his friends. He's a nice guy, but a bit of a pushover, tending to be shoved around by his friends -- especially the more extroverted and insensitive Plucky.

* {{Adorkable}}: He's rather likable due to his nervous and easygoing personality.
* BewareTheNiceOnes: He's very sweet-natured, and usually tries to avoid conflict, but DO NOT push him too far. Seriously. Just don't.
* BigEater: The one thing he does share with animated works' usual depictions of pigs is that he loves to eat.
* ButtMonkey: Lots of bad things happen to him.
* TheChewToy: Not that he deserves it, considering he's one of the sweetest characters of this show.
* ExtremeDoormat: Usually to Plucky's antics.
* FourTemperamentEnsemble: The Melancholic.
* InformedJudaism: In "It's a Wonderful Tiny Toons Christmas Special", a menorah can be seen in the window of his house, implying that his family is Jewish. Most likely, this is meant to be a joke, as they do not keep kosher, as Hamton once tried to cook a lobster, and indeed, they aren't even kosher themselves, being pork.
* InterspeciesRomance: He has dated Fifi, a skunk, a few times.
* {{Leitmotif}}: More often than not, Hamton is musically represented by "Old [=McDonald=] Had a Farm".
* NeatFreak: Contrary to the usual depiction of pigs in fiction, he detests sloppiness and germs.
* NiceGuy: Like Porky Pig.
* NiceMeanAndInbetween: The Nice to Plucky's Mean and Buster's In-Between. He typically acts nice and {{Adorkable}}.
* SensitiveGuyAndManlyMan: Sensitive Guy to Plucky's Manly Man.
* {{Sidekick}}: When Plucky is hired as Buster and Bab's sidekick, he complains, ''"Hamton's'' a sidekick! He has all the earmarks of a sidekick!" and promptly [[VisualPun pulls Hamton's ear to reveal the word "sidekick"]]. Interestingly, Hamton ended up being Plucky's sidekick in a lot of the shorts, most notably the Franchise/{{Batman}} parody, in which he plays "Decoy", Batduck's answer to ComicBook/{{Robin}}.
* SpeciesSurname: His last name is Pig.
* SpellMyNameWithAnS: The correct spelling is "Hamton", though some fans still somehow hear a "p" in the middle. It might also have to do with the fact that Hamton's name was actually misspelled in one of the show's credits as Hampton.
* StraightMan: The trope title is actually used when he applied to join the cast because "I react to characters funnier than I am."

[[folder: Dizzy Devil]]
!Dizzy Devil

-->''WesternAnimation/LooneyTunes'' counterpart: The Tasmanian Devil.
-->Voiced by: Creator/MauriceLaMarche (English), Shunsuke Takamiya (Japanese), Carmelo Fernandez (Latin American Spanish), Michel Modo (French)

A hyperactive young "Tasmanian Devil", Dizzy is a fairly one-dimensional character; he likes having a good time, whether that involves partying or just stuffing his face with absolutely anything. He does have a bit of a temper, though. He's a secondary character, mostly relegated to starring in shorts alongside the others rather than starring in his own stories.

* AlliterativeName: Given name and surname both begin with D.
* AntiVillain: It's hard to remember that he's actually supposed to be one of the show's ''bad guys'', even being freed from the box of monstrous characters alongside Elmyra and Montana Max in the pilot.
* BigEater: Like Taz.
* CharacterizationMarchesOn: In the pilot, he's actually introduced as an antagonistic character. He eventually grows into the more friendly party animal that he's better known as.
* ChickMagnet: When he's not acting like his adult counterpart, Dizzy is usually in the company of hot, human teenage girls who are crazy about him.
* ExtremeOmnivore: To the point where the male characters often play a game with Dizzy called "Will Dizzy Eat It?"
* KavorkaMan: Popular with the ladies not because of his looks, but because the ladies always have a great, fun time when they're with him.
* NiceHat: His beanie.
* TrademarkFavoriteFood: Pizza rolls.
* WildCard: Even the friendlier "party animal" Dizzy had his antagonistic moments, usually when he let his temper or appetite get the better of him (or when he got the homework assignment "eat a bunny").

[[folder: Montana Max]]
!Montana Max

-->''WesternAnimation/LooneyTunes'' counterpart: Yosemite Sam.
-->Voiced by: Creator/DannyCooksey (English), Creator/UraraTakano (Japanese), Edilú Martínez (Latin American Spanish), Emmanuel Garijo (French), Luq Hamet (French/replacement voice)

The primary male antagonist of the show, a human kid whose ultra-rich family gives him a lot of finance-based weight to throw around. Selfish, greedy and a vicious little snot, he takes great pleasure in making everyone else utterly miserable whenever he can.

* AlliterativeName: Both parts of his name begin with the letter M.
* BigBadEnsemble: He and Elmyra are the show's most prominent antagonists, though he's way more malicious than the latter.
* CharacterizationMarchesOn: Became less villainous as time went on, even being the protagonist of some cartoons. He was still a bit of a jerk, but not exactly villainous.
* CorruptCorporateExecutive: He owns a number of rather destructive businesses, which Plucky often tries to stop as the "Toxic Revenger".
* EvilLaugh: Quite often laughs when things go his way.
* EvilFormerFriend: As stated below, Monty was once friends with Buster until money turned him into a complete {{jerkass}}.
* FinalBoss: In most of the video games.
* HairTriggerTemper. Like Yosemite Sam.
* HumansAreBastards: He's one of the few human characters on the show and is a complete jerk.
* {{Jerkass}}: One of the best examples of this is his owning a toy store called Toys 'R' Mine at one point. Any kid who bought something there had to deal with the heartbreak of the giant Max cutout atop the sign ''stealing it back'' as they exited.
* {{Kidanova}}: In the prom episode, he's initially all fired up to go out on a date with the "cute daughter" of his parents' friends. He loses his enthusiasm when he learns that said "cute daughter" is none other than Elmyra.
* MythologyGag: According to the series intro episode, Montana Max was originally pitched as the protagonist, but was rejected, and Buster & Babs' success at getting their own show is part of the reason why he hates them. This is a tongue-in-cheek reference to the fact that WesternAnimation/DaffyDuck was the "flagbearer" of the original WesternAnimation/LooneyTunes, until that position was stolen from him by WesternAnimation/BugsBunny.
* NoIndoorVoice: Full-fledged at first, but [[VillainDecay fizzled off a bit as time went on]].
* PetTheDog: He has his moments, but those are usually towards Elmyra and no one else.
* RagsToRiches: "Citizen Max" states that his family used to be poor.
* RichBastard: He's obscenely wealthy, but uses his fortune as an excuse to pick on the other characters and make their lives miserable.
* RunningGag: Monty loves to swim in his private pool, but his antagonist in any given episode has been known to empty the pool right after he jumps off the diving board.
* ScrewTheRulesIHaveMoney: He sometimes bribes people to get his way, one such person being the host of the game show Win, Loose, or Kerplowey.
* SpoiledBrat: He is a complete bastard and does everything he can to get his way.
* StartOfDarkness: As chronicled in [[Film/CitizenKane "Citizen Max"]], Monty UsedToBeASweetKid back when his family was poor. He even used to be friends with Buster Bunny. Unfortunately, when his family won the lottery, Max turned into the money-grubbing sociopath the rest of Acme Acres knows and loathes.
* VillainDecay: See CharacterizationMarchesOn above.
* VocalEvolution: His voice actor being 14 when the show began, Max's voice got a little deeper in the later episodes.

[[folder: Elmyra Duff]]
!Elmyra Duff

-->''WesternAnimation/LooneyTunes'' counterpart: Elmer Fudd.
-->Voiced by: Creator/CreeSummer (English), Chie Kojiro (Japanese), Josefina Nuñez (Latin Americam Spanish/1st voice), Giset Blanco (Latin American Spanish/2nd voice), Véronique Alycia (French)

The primary female antagonist of the show, in contrast to Montana Max, Elmyra doesn't ''mean'' to be a bad guy. She's a very loving girl with a huge fondness for animals... she's just a complete and utter ''moron'' who fails to realise she's being too rough and clumsy with her pets. This results in a disturbing amount of on-screen injuries -- and off-screen implied fatalities -- and makes her more hated by her animal toon classmates than Montana Max. They can easily pay Max back in kind, but Elmyra's obliviousness means she lacks malice, which means their attempts to get her back usually don't work.

* AllGirlsWantBadBoys: She likes [[RichBastard Montana Max]], and in ''WesternAnimation/PinkyElmyraAndTheBrain'' she has a crush on a slob named Rudy Mookich who is also a {{Jerkass}}.
* AmbiguouslyBi: Elmyra has a crush on Max and one short called "Can't Buy Me Love" has Elmyra meet an evil little girl called Rhoda. Elmyra sees hearts and positively MELTS when Rhoda says she'll let her be her best friend, and spends the rest of the picture bending over backwards to make Rhoda like her.
* AndCallHimGeorge: The treatment of her pets seriously harms them and in some cases even kills them.
* AntiVillain: Type IV, especially when in comparison with Montana Max and Gotcha Grabmore
* BabyTalk: It's rare that she ''doesn't'' talk like this.
* BaldWomen: In a few episodes and the ''Babs' Big Break'' video game, she is revealed to be bald (like her mentor, Elmer Fudd), and thus she wears a wig.
* BigBad: She is portrayed as the main antagonist in the Spring Break special.
* ChronicPetKiller: Ironically, despite her good intentions, she was far more successful in killing wabbits than her counterpart.
* {{Cloudcuckoolander}}: Has a pretty bizarre interpretation of how the world works, seeing that she is unaware that her affections towards animals is harmful to them.
* CompositeCharacter:
** While her name and appearance are obviously based on Elmer Fudd, her personality of adoring animals while obliviously causing them serious harm makes her more like Hugo the Abominable Snowman.
** She also resembles Suzanne from ''A Kiddies Kitty'', almost to the point of being a SuspiciouslySimilarSubstitute.
* DisabilityImmunity: In the short, "Drooley Davey" from the episode, "The Wide World of Elmyra", she's too stupid to ''even feel pain'' or at least not realizing [[BrickJoke she's hurt until later in the short.]]
* TheDreaded: ''Everybody'' in Acme Acres is afraid of Elmyra. [[EvenEvilHasStandards Even Montana Max]].
* FieryRedhead: She has red hair, but she only gets mad when her "pets" try to get away.
* {{Foil}}: To Elmer Fudd. He's a hunter who's unable to pose an actual threat to an animal; she's a girl who unintentionally harms animals by her love for them.
* FoolishSiblingResponsibleSibling: In the two "Elmyra's Family" episodes, she's seen as the foolish sibling to her little brother Duncan's responsible sibling.
* GenkiGirl: Often very cheerful and energetic.
* TheGlomp: Gee, wonder why she's TheDreaded?
* GoKartingWithBowser: While normally an antagonist (albeit unintentionally), there are instances where Elmyra is shown to be a good friend to the Tiny Toons, especially Furrball at times.
* HairDecoration: A bow with a [[RedRightHand skull]] on it. Since her interests are typically girly and all her intentions are genuinely good, this little detail is LeaningOnTheFourthWall more than anything.
* HoistByHisOwnPetard: In her skit in the "Night Ghoulery" special, she creates a FrankensteinsMonster "super-pet" that can finally take her level of loving. It promptly proceeds to start loving her back with the ''exact'' same kind of dimwitted, over-enthusiastic to the point of painful "love" as she gives all her pets.
* HollywoodToneDeaf: She's a terrible singer voiced by ''Cree Summer''.
* IdiotHoudini: As per the "rules" of Looney Tunes, the fact that she means well and her antagonism comes from the fact she's an absolute moron prevents her from getting the same level of karmic retribution as more deliberate villains get, even though she's ultimately more dangerous than they are.
* ImplacableWoman: She can not be escaped.
* {{Leitmotif}}: She is musically represented by "I Went to the Animal Fair".
* LethallyStupid: In contrast to Elmer's TooDumbToLive.
* MadLove: Towards Montana Max or also to her pets in general.
* NaiveAnimalLover: Her undying affection for animals keeps her oblivious to how dangerous some of them are, especially those with sharp teeth and claws. When she does manage to get her hands on them, however, they find out from the way she treats them that she's even more dangerous than they are.
* NiceGirl: In spite of her obsession towards animals, Elmyra is a truly kind hearted girl who means well despite the damage she causes.
* NightmareFetishist: In "Toons from the Crypt", although initially terrified of her zombie pets coming back to get her, she quickly stops caring and is just happy to have them back. At the episode's end, it's got her hopes up so much that she runs off to her pet cemetary to dig them all up herself!
* ObliviouslyEvil: She has no idea that showing her affection to animals often kills them. For example, in ''Whale's Tales'', when Elmyra finds out whales are used to make cosmetics (as in they're made ''from'' whales) she's so horrified she faints.
* PunchClockVillain: In "Prom-ise Her Anything", she shows more interest in dating Montana Max than trying to chase after animals.
* StalkerWithACrush: She is shown to be this towards Montana Max in episodes where she dates him, such as "Prom-ise Her Anything" and "My Dinner with Elmyra" (Part of "Love Disconnection").
* TookALevelInJerkass: In the Spring Break special, she doesn't seem to be oblivious of the pain she causes animals and seems to get a kick out of tormenting them.
* TomboyAndGirlyGirl: The Girly Girl to Mary Melody's tomboy. Elmyra mostly wears a dress and is into dolls, tea parties, and cute things like animals.
* VillainSong: In the Spring Break special, which portrays her as being deliberately malevolent, she sings "I'll Be Chasing You", a parody of Music/ThePolice song "Every Breath You Take".

[[folder: Fifi la Fume]]
!Fifi la Fume

-->''WesternAnimation/LooneyTunes'' counterpart: WesternAnimation/PepeLePew.
-->Voiced by: Creator/KathSoucie (English), Junko Asami (Japanese), Carmen Olarte (Latin American Spanish), Sybille Tureau (French), Barbara Tissier (French/replacement voice)

A lustful female skunk filled with deep passion and an all-consuming desire for a soulmate, Fifi comes from an implicitly poor background -- living in a derelict car in a junkyard in Acme Acres -- and is determined to find herself a Mr. Right. No matter how badly her smell and/or her aggressive come-ons tend to hinder her effort.

* AbhorrentAdmirer: Though, much like her SpearCounterpart (Pepe), it's only her smell and aggressive come-ons that are abhorrent. In "Aroma Amore" from "Furrball Follies" a nameless wolf and Furrball both clearly are attracted to her, but her scent is unbearable.
* AccessoryWearingCartoonAnimal: The three lead cheerleaders, Babs, Shirley and Fifi, represent three different aspects: Babs Bunny is implied to be fully dressed but goes [[BarefootCartoonAnimal without shoes]]. Shirley wears a hairbow and [[HalfDressedCartoonAnimal pink sweater but no pants]]. Fifi, for the most part, wears just a hairbow; there will be times she may wear clothes but is usually "nude".
* BreakTheCutie: Falls under this a lot. Tends to take losing her love in her shorts a lot more harshly than her predecessor ever did, was forced to be Elmyra's pet for a while, and her movie idol turned out to be a massive {{Jerkass}}. Though the last of which resulted in one of the most memorable moments in the series when she finally snaps at his attitude towards her.
* ButtMonkey: More like "Butt Skunkey". She is usually abused and ignored for no reason.
* CatchPhrase: "Do not fear my dear, Fifi La Fume is here!"
* DoggedNiceGirl: She has problems controlling her musk and she can be rather aggressive in pursuing guys, but she genuinely is an affectionate and friendly girl.
* EverythingSoundsSexierInFrench: She has a French accent and is very attractive.
* FunnyForeigner: Like Pepe, she has a French accent and her unrequited affections can lead to comedic moments.
* TheGlomp: Gives a huge hug to some of the boys she hits on.
* HairDecorations: Wears a pink bowed ribbon in her hair.
* HelloNurse: Played with. She ''would'' knock 'em dead with her good looks... if it wasn't for her scent and her aggressive way of coming on to guys she likes. Case in point, when Furrball saw her, he immediately jumped in her arms. All was great until he smelled her and noticed her tail stripe.
* IJustWantToBeLoved: What it seems she really wants is someone to love her. When Furrball and Calamity managed to remove the skunk-like looks before she could catch up to them and tell her they haven't seen any "cute boy skunk", she quickly breaks down in tears and thinks she's been abandoned and no one loves her.
* InterspeciesRomance: Like Pepe, she mistakes other animals for fellow skunks and runs after them. Her hit list has included Furrball, Calamity, Beeper, and Dizzy. She also went to the prom with Hamton, and his interest in her is a gag in several episodes.
* {{Leitmotif}}: "Alouette". One of the few characters to have one.
* NiceGirl: Next to Hamton, she is one of the most legitimately kind-hearted characters.
* NiceMeanAndInbetween: The Nice to Babs' Mean and Shirley's In-Between. She acts as the kind-hearted hopeless romantic.
* NoGuyWantsToBeChased: This is her main problem, though unlike her ''WesternAnimation/LooneyTunes'' counterpart, she doesn't mind being chased. Unless it's by ''Elmyra'' of course.
* NoSenseOfPersonalSpace: Toward her love interests.
* OutOfFocus: Although technically one of the three female main protagonists, alongside Babs and Shirley, she tends to appear the least, perhaps because like her "predecessor", she's a bit of a one-joke toon.
* PeekABangs: One of her eyes is obscured by her hair.
* PrehensileTail: She can use her tail to grab "boyfriends", as a bat (As seen in "Buster at the Bat"), as a shield (As seen in the "Defenders of the Universe" licensed game), and to spray stink (Being a skunk and all).
* RidiculouslyCuteCritter: She's a quite cute skunk.
* SmellySkunk: Unlike Pepe, she can actually control her scent. At least, to a degree; part of the problem is not only do guys fear that she ''will'' start stinking if they let her get close, but sometimes she really does walk around with constant musk flowing from her (the "How I Spent My Summer Vacation" special is a good example). Still, she can control it better than he does; normally she only tends to lose control when she's getting worked up over a cute guy.
* SpellMyNameWithAnS: Some people (including some who claim to be the aforementioned fans) still think her name is "Le Fume". Like Hamton as noted above, this is probably because the credits sometimes misspelled it as "Le Fume".
* StalkerWithACrush: Much like her predecessor, Pepe, only she's never had to fight off guys chasing her (in fact, she prefers it).

[[folder: Shirley [=McLoon=]]]
!Shirley [=McLoon=]

-->''WesternAnimation/LooneyTunes'' counterpart: Melissa Duck.
-->Voiced by: Gail Matthius (English), Creator/MikaKanai (Japanese), Maria T. Hernandez (Latin American Spanish), Joëlle Guigui (French)

A female avian toon of indeterminate species -- her name suggests that she's a loon, but her appearance is near perfectly that of a duck -- Shirley may speak with a ValleyGirl accent, but don't let that fool you. Under her vapid-seeming speech patterns and neo-hippie beliefs lies a keen mind and a formidable grasp of mystical powers. She is more or less Plucky's girlfriend, although Fowlmouth keeps trying to woo her away from him.

* UsefulNotes/AmericanAccents: ValleyGirl. Justified, as her voice actress played a Valley girl before (though when Gail Matthius played Valley Girl Vicki on ''Series/SaturdayNightLive'', it didn't sound as high as it does here. Whether Matthius perfected her Valley Girl voice between her short time on ''SNL'' and when she was hired to do ''TTA'' or her voice was pitched up after recording her lines isn't known).
* BewareTheNiceOnes: Do NOT make her angry. Seriously, don't.
* {{Cloudcuckoolander}}: Though actually a very smart one.
* GranolaGirl: She's into E.S.P., telekinesis, astrology, crystals, tarot cards, tea leaves, palm reading, levitation and reincarnation.
* HalfDressedCartoonAnimal: Wear only a pink shirt.
* InterspeciesRomance: A loon in a love triangle with a chicken and a duck.
* LevitatingLotusPosition: She does this as part of her psychic powers.
* NewAgeRetroHippie
* NiceMeanAndInbetween: The In-Between to Fifi's Nice and Babs' Mean. She's usually pretty collected, but isn't above making [[DeadpanSnarker snide remarks]].
* NonmammalianHair: She has long, blonde hair.
* PinkMeansFeminine: She wears pink clothes.
* PsychicPowers: Has psychic/mystical powers. When she gets angry, it's like a scene out of ''{{Carrie}}'' (in fact, there was an episode where she went berserk at a prom like in the climax of that work, albeit toned down for the younger crowd [the pig's blood dumped on her was actually fruit punch and she only ended up flooding the gym instead of killing everyone]. Observing this, Babs even namedrops the film for ParentalBonus purposes).
* SeldomSeenSpecies: Not many loons in fiction. And she looks like a duck.
* ShoutOut: To actress Shirley [=MacLaine=]; by the time this series launched, she had become notorious for her professed beliefs in reincarnation, [=UFO=]s, and various New Age phenomena. (The two Shirleys actually meet in one short.)
* SpellMyNameWithAnS: Some think her name is Shirley THE Loon. Including the programmers of the Tiny Toons videogame.
* {{Trickster}}: As Plucky finds out in "Never Too Late To Loon".

[[folder: Furrball]]

-->''WesternAnimation/LooneyTunes'' counterpart: Sylvester (although he also shares traits with Penelope Pussycat).
-->Voiced by: Creator/FrankWelker when voiced at all, except for one episode when Creator/RobPaulsen voiced him instead (English), Creator/RyuzouIshino (Japanese), Rafael Monsalve (Latin American Spanish), Roland Timsit (French)

An incredibly unlucky alley cat who struggles to fend for himself on the streets of Acme Acres, sometimes being so desperate as to tolerate living with Elmyra for a while in order to attain food and shelter.

* AntiHero: Has been every type at least once.
* AntiVillain: Even at his most antagonistic, his actions are out of an instinct to survive, rather than genuine hostility.
* AttractiveBentSpecies: He gets a stripe in the "Aroma Amore" segment of the "Furrball Follies". As a result, Fifi sees him as a cute boy skunk.
* BreakTheCutie: Things just never seem to go right for him.
* ButtMonkey: Probably the biggest on the show next to Plucky. He's called "unlucky" in the theme song for a reason. That said, despite his bad luck, he's still a bit luckier than other cartoon cats like [[WesternAnimation/LooneyTunes Sylvester]] or [[WesternAnimation/TomAndJerry Tom]].
* CuteKitten: He's a cat and can be adorable in his own way.
* CuteMute: A mute CuteKitten.
* GenderFlip: Furrball acts more like Penelope Pussycat than Sylvester,
* MasculineGirlFeminineBoy: The Feminine Boy to Sweetie's Masculine Girl. These two are homeless creatures but Furrball's too timid and meek to stand up for himself against bigger animals and Sweetie is tougher and more aggressive and even intimidates Furrball who's bigger than her.
* PinkGirlBlueBoy: The Blue Boy to Sweetie's Pink Girl.
* RidiculouslyCuteCritter
* SilentSnarker: After he lost his rights to speak on the show, at any rate.
* SpellMyNameWithAnS: People can't seem to decide whether or not his name is "Furrball" with two 'r's, or "Furball" with one 'r'. Generally, either spelling seems to be okay with the fandom.
* TeamPet: Whenever he's not shown to be a homeless stray, he's often someone's pet.
* TeamRocketWins: While he never won against Sneezer, he actually won against Sweetie in "Strange Tales of Weird Science".
* ThrowTheDogABone: Well, a cat anyway. Very rarely, an episode will end on a happy note for him.
* TheVoiceless: Except for at least three occasions. Usually he'd just meow, but one time he had a voice that sounded like a higher-pitched version of [[ScoobyDoo Fred Jones]].

[[folder: Sweetie Pie]]
!Sweetie Pie

-->''WesternAnimation/LooneyTunes'' counterpart: Tweety Bird (specifically with the nastier attitude he had in his earliest appearances).
-->Voiced by: Creator/CandiMilo (English), Creator/YukoMizutani (Japanese), Joëlle Guigui (French)

An ironically named pink female canary whose cutesy appearance hides a sarcastic attitude and an immense sadistic streak. She loves to feign innocence and harmlessness, both to lure in victims for her to abuse and to get away with tormenting other toons. She has a particular relish for harassing the luckless Furrball.

* BitchInSheepsClothing: She may seem nice at first glance, but she is really cruel and mischievous.
* ComedicSociopathy: Her favorite type of humor.
* CuteIsEvil: Much like her inspiration, she is an adorable bird.
* ADayInTheLimelight: The result of her forcing Buster and Babs to give her a ThreeShorts episode of her own.
* FeatheredFiend: A bully and a bird.
* IronicName: She is called "Sweetie" but is one of the nastiest characters on the show, perhaps even more so than Montana Max.
* {{Jerkass}}: She always torments Furrball.
* LittleMissSnarker: It's perhaps a warning of her real nature that she almost never speaks without snarking about something.
* MasculineGirlFeminineBoy: The Masculine Girl to Furrball's Feminine Boy. These two are homeless creatures but Furrball's too timid and meek to stand up for himself against bigger animals and Sweetie is tougher and more aggressive and even intimidates Furrball who's bigger than her.
* MeanCharacterNiceActor: Subverted, it's implied she and Furball are "friends" of sorts outside their cartooning careers and that she ''still'' treats him like crap even then!
* MythologyGag: Sweetie Pie is based primarily on Bob Clampett's Tweety (as opposed to Friz Freleng's Tweety), who was pink and malicious.
* PinkGirlBlueBoy: The Pink Girl to Furrball's Blue Boy.
* PinkMeansFeminine: She is a pink female bird.
* SitcomArchNemesis: For Furrball.
* {{Trickster}}: She keeps on messing with Furrball.

[[folder: Calamity Coyote]]
!Calamity Coyote

A hyper-intelligent and affable male coyote, rarely seen speaking.

* AlliterativeName: Both parts of his name begin with C.
* BigOlEyebrows: He has huge eyebrows.
* JerkassBall:
** The episode "Hero Hamton" which sees him as a member of Montana Max's team and even joins in for a few KickTheDog moments.
** In "It's Buster Bunny Time" he tried to catch Buster for Elmyra, and got his punishment in the end.
* NiceGuy: Calamity is generally characterized as nice. In fact, he does not seem to enjoy chasing Little Beeper, instead preferring to help others or invent things.
* TheSmartGuy: Like Wile E. Coyote, he is intelligent and devises gadgets.
* SiblingRivalry: Implied to be Little Beeper's adopted brother.
* SpeciesSurname: His name is Coyote.
* TalkingWithSigns: It was always troublesome whenever he wanted to talk on the phone.
* TeamRocketWins: In "Love Stinks".
* TheOneWhoWearsShoes: They're ''all'' he wears.

[[folder: Little Beeper]]
!Little Beeper

-->''WesternAnimation/LooneyTunes'' counterpart: Road Runner.
-->Voiced by: Frank Welker.

A male road runner most notable for his super-toon speed and his enjoyment of harassing and tormenting Calamity.

* {{Jerkass}}: He has run over Calamity with a truck for no reason many times (often straight after another painful experience). Even worse is in "A Piece of Mind" -- in a flashback, it's hinted that Beeper and Calamity are actually ''adoptive brothers''. [[SiblingRivalry Yikes]]...
* {{Narcissist}}: Road Runners like Little Beeper are said to be quite vain and enjoy seeing their reflections.
* SiblingRivalry: Implied to be Calamity's adopted brother.
* SuperSpeed: Like Road Runner, he moves very fast.
* TheVoiceless: Also like Road Runner, he only says "Beep Beep".

[[folder: Fowlmouth]]
-->''WesternAnimation/LooneyTunes'' counterpart: WesternAnimation/FoghornLeghorn.
-->Voiced by: Creator/RobPaulsen (English), Philippe Peythieu (French/only in some episode), Vincent Violette (French/''How I Spent My Vacation'')

A motor-mouthed, profanity-spewing, arrogant young cockerel who manages to achieve the incredibly difficult task of making Plucky seem like a well-rounded and sensitive character by comparison. He is deeply infatuated with Shirley and constantly tries to steal her away from Plucky, but he's such an arrogant, pig-headed chatterbox that she rarely returns his feeling.

* EveryoneHasStandards: He draws the line at swearing in front of little kids.
* HollywoodTourettes: Never called out by name, but treated exactly like it otherwise.
* InterspeciesRomance: Has a crush on Shirley.
* NotInFrontOfTheKid: He swears a lot, but never when there are small children present, because that would be "crude."
* SirSwearsalot: Yet his swears are always bleeped out of course... Paulsen may not even be making real curse words! His most frequent choice is "[[GoshDarnItToHeck dadgumit]]"!
* ToothyBird: He has teeth.

[[folder: Concord Condor]]
!Concord Condor
-->''WesternAnimation/LooneyTunes'' counterpart: Beaky Buzzard.
-->Voiced by: Rob Paulsen (English), Naoki Tatsuta (Japanese)

One of the least important members of the Looniversity students, a dimwitted and gullible male condor.

* AlliterativeName: First and last names both begin with the letter C.
* CatchPhrase: "Yup, yup, yup, yup!" and "Nope, nope, nope, nope!" Borders on VerbalTic.
* TheFool
* FriendToAllLivingThings: In the short, "Concord the Kindly Condor" (part of "Toons From the Crypt"), Concord becomes a veterinarian, spending all his time helping sick and defenseless forest animals, and protecting them from his three older brothers, who want to hunt and eat them and want Concord to do the same.
* SpeciesSurname: He's a condor and not a buzzard.
* WhiteSheep: In the short, "Concord the Kindly Condor" (part of "Toons From the Crypt"), Concord is revealed to have three mean (and much bigger) older brothers who want him to hunt and eat defenseless animals instead of helping them.

[[folder: Gogo Dodo]]
!Gogo Dodo
-->''WesternAnimation/LooneyTunes'' counterpart: The Dodo from "WesternAnimation/PorkyInWackyland", who is apparently his father.
-->Voiced by: Frank Welker (English), Mitsuru Ogata (Japanese), Mario Santini (French)

A hyperactive and crazy male "Dodo Bird" from the ultra-loony region of Wackyland, beyond Acme Acres. Mostly a cameo character who tends to show up for gratuitous random madcap humor.

* AdvertisedExtra: One of the few characters mentioned in the theme song and gets a fair bit of attention in the SeriesBible. After the first season, however, he's usually OutOfFocus.
* BlackBeadEyes: As a tribute to the original Dodo bird, he's the only recurring character to have them.
* CatchPhrase: "Cuckoo! Cuckoo!" Doubled with his job as the cuckoo bird in every clock on the show -- no matter if said clock is an actual cuckoo clock or not. Also, his constant "Vo-do-de-oh, vo-do-de-oh"-ing.
* {{Cloudcuckoolander}}: Quoth the SeriesBible: "Gogo operates by his own set of rules, which means no rules."
* DemotedToExtra: It seems like he was originally intended to be a principal character; he gets a fair bit of attention in the SeriesBible, he's one of the characters to be mentioned in the theme song, and he plays fairly large roles in the OriginsEpisode and several episodes early in Season One ("Her Wacky Highness", "Sawdust and Toonsil", etc.). In later episodes he's a very minor character.
* LastOfHisKind: Referred to as the last of the Dodos in a couple of episodes, though usually only in passing.
* TheMadHatter: And how! The theme song says it best:
-->''"And Gogo is INSANE!"''
* PungeonMaster: Usually ''visual'' puns -- most of his wacky stunts that aren't completely random or nonsensical are pun-based.
* RealityWarper: More so than any other Tiny Toon.

[[folder: Li'l Sneezer]]
!Li'l Sneezer

-->''WesternAnimation/LooneyTunes'' counterpart: Sniffles.
-->Voiced by: Kath Soucie (English), Creator/MegumiHayashibara (Japanese/1st voice), Creator/IkueOtani (Japanese/2nd voice), Edilú Martinez (Latin American Spanish), Régine Teyssot (French)

Another minor bit-character in the Looniversity students, Li'l Sneezer is a cute, motor-mouthed, innocent young mouse who suffers from chronic allergies, which is a problem with his super-strong sneezes.

* AlternateUniverseReedRichardsIsAwesome: In the Christmas special, his counterpart in a world where Buster Bunny never existed is named Sleazer and is an aggressive security guard.
* CreatorsPet: In-universe. He is so well liked by Spielberg, he can get him to calm down when Buster and Babs got him really angry.
* DeliberatelyCuteChild
* MeaningfulName: He's little. He sneezes a lot.
* MotorMouth: Quite often talks rapidly.
* RidiculouslyCuteCritter
* SneezeOfDoom: His sneeze is destructive. In the ''[[VideoGame/TinyToonAdventuresBustersHiddenTreasure Buster's Hidden Treasure]]'' video game, he is one of Buster's three helpers, and in certain levels of the game, Buster can use his extreme sneeze [[SmartBomb to clear the screen of enemies]].
* ThingsThatGoBumpInTheNight: For those scary things, Sneezer is this to them. In the one episode when the "Things That Go Bump" are job hunting, the mention that the job was for his place made them all scatter, save one who was TooDumbToLive.
* TrademarkFavoriteFood: Cheese.

[[folder: Other characters]]
!!Byron Basset

-->''WesternAnimation/LooneyTunes'' counterpart: Sam the Sheepdog.

* TheStoic: Usually.
* TheVoiceless: Never says anything other than the occasional "Woof."

!!Mary Melody

-->''WesternAnimation/LooneyTunes'' counterpart: None, though she looks like a modern take (read: less offensive take) on So White from the [[BannedEpisode Censored 11]] cartoon, ''WesternAnimation/CoalBlackAndDeSebbenDwarfs''.
-->Voiced by: Cindy [=McGee=] (English, "Furrball Follies"), Creator/CreeSummer (English, other appearances) Véronique Alycia (French/1st voice) Régine Teyssot (French/2nd voice)

The only other major human character in the Looniversity students, Mary is a friendly girl who just doesn't really have anything going for her, relegating her to bit-part roles and cameos.

* AlliterativeName: Her given name and her surname both start with M.
* BlackBestFriend: She's the only human character who means no malice to the animal characters.
* FlatCharacter: She does not have any characteristics.

* ChuckCunninghamSyndrome: He only makes two brief appearances on the show (one being a still shot) before being removed entirely out of concerns that his character would be too offensive.

!!Sandy Witch

-->Voiced by: Sally Struthers.

''WesternAnimation/LooneyTunes'' counterpart: Witch Hazel

* BaldWomen: Downplayed in that her true form has some hair, but what little hair she has doesn't cover much of her scalp.
* BalefulPolymorph: Buster defeats her by using magic dust to turn her into a fish in a bowl.
* BitchInSheepsClothing: She first appears in the form of a cutesy girl offering Babs and Buster a meal, but it soon turns out that she's really a witch and that she was really trying to fatten them up so she could eat them.
* PunnyName: Her name sounds close to "sandwich".
* WickedWitch

!!Arnold the Pitbull

-->Voiced by: Creator/RobPaulsen (English), Creator/TomomichiNishimura (Japanese), Orlando Noguera (Latin American Spanish)

* AngryGuardDog: He's this anytime he's with Montana Max.
* TheAhnold: He is muscular and speaks in an Austrian accent. He's got a little bit of the TotallyRadical '80s icon [[ Spuds Mackenzie]] mixed in for more laughs.
* DumbMuscle: Usually he appears as an antagonist to Buster, Babs and other Tiny Toons, but he ends up getting bested by them in one way or another for his stupidity.
* GoKartingWithBowser:
** In "Prom-ise Her Anything", he and his girlfriend, Arnolda attend the prom alongside the protagonistic toons.
** In the Spring Break special, he joins the protagonistic toons on their spring break, and even provides back-up vocals for the "Nothin' Can Be More Fun" music video.

** In ''Prom-ise Her Anything'' he is revealed to have a girlfriend named Arnolda, who looks distressingly like him.

* FieryRedhead: Has red hair.
* {{Gainaxing}}: Her "bosom" bounces with almost every movement she makes.
* GenkiGirl: She is an energetic girl.
* InkSuitActor and NoCelebritiesWereHarmed: She's a spoof of comic Julie Brown, who also voices her.
* MsFanservice: The main reason why fan remember her despite appearing only in one episode. She is sexy and really, really buxom.
* OneShotCharacter: She appears only in the Tiny Toon Music Television episode segment, "Just Say Julie Bruin".
* PettingZooPeople: She is an anthropomorphic female bear.
* RedheadInGreen: A redhead that wears a green dress.

-->Voiced by: Creator/TressMacNeille, Creator/JimCummings, Creator/CreeSummer, and Whitby Hertford, respectively.

A group of fleas who happen to live on Furrball's back.

* AffectionateParody: Of the Mousekewitz family from ''WesternAnimation/AnAmericanTail''. It is no coincidence that ''An American Tail'' and ''Tiny Toon Adventures'' were produced by Amblin Entertainment.
* ADayInTheLimelight: They only appear in a couple episodes, but they're the central focus of each of them.
* FourLeggedInsect: All of them.
* IHaveYouNowMyPretty: A greedy, fat tick crimelord almost forced Itchy to marry him in one episode. Definitely {{Squick}}.
* IWantSong: "Fur Fur Away" sung by Flio, which bears a striking, deliberate similarity to "Somewhere Out There".
* LittleMissSnarker: Itchy
* ShesGotLegs: Itchy
* UnnamedParent: The parents are only known as Mama and Papa.

!!Elmyra's Family (Emily, [=MacArthur=], Amanda, Duncan, Baby, and Grandma)

Elmyra Duff's family, consisting of her mother (Emily), father ([=MacArthur=]), older sister (Amanda), two younger brothers (Duncan and Baby), and grandmother (Grandma). They appear in the episodes, "Take Elmyra Please" and "Grandma's Dead.

* ADayInTheLimelight: They are the main focus of the episodes they appear in.
* FoolishSiblingResponsibleSibling: Duncan acts as the responsible sibling to Elmyra's foolish sibling.
* JerkWithAHeartOfGold: While Amanda does tell Duncan to get a life and talks harshly to both him and Elmyra, she does show a small act of kindness towards Elmyra in "Grandma's Dead" when one of her pet hamsters dies. She tries to cheer her up, telling her, "Come on, don't be sad, be the other way".

* NoNameGiven: Baby and Grandma don't seem to have their own names.

During their conversation, Amanda tells Stephanie that she is lucky to live in a family whose parents are always gone and without brothers, sisters, or pets.
* PoorlyDisguisedPilot: The two episodes they appeared in were meant to serve as part of a spin-off focusing on them. Although the series was never picked up, Elmyra did eventually end up starring in [[WesternAnimation/PinkyElmyraAndTheBrain another show]], which they got left out of.
* SuperStrongChild: In "Take Elmyra Please", Baby has super strength, which he uses to bend the bars on his crib and go on a mini-rampage in the living room. However, in "Grandma's Dead", he does not display any of his strengths and acts more like a typical baby.
* YouGottaHaveBlueHair: Amanda has purple hair. Given the fact that Mac has brown hair and Emily has red, it's possible Amanda dyed her hair purple.

A malicious, cruel, snooty, rich male rat who attends Perfecto Prep and aspires to being Buster's arch-enemy.

* SpeciesSurname: He's a rat named Rat.

!! Melvin the Monster

* SuddenlyVoiced: He mostly speaks in growls, roars, and the occasional woof. When Babs and Splicer argue over who he should help, he briefly breaks character and says, "I feel so torn.".

!!The Woodpile Possum Clan

-->Voiced by: Creator/RobPaulsen (Banjo)

The first antagonistic group that Buster and Babs meet during the journey downriver as part of ''[[WesternAnimation/TinyToonAdventuresHowISpentMyVacation How I Spent My Vacation]]''; a clan of seven deformed-looking possum hicks who live in the backriver regions of Acme Acres. Although the youngest son, Banjo, takes a swift liking to Buster for his ability to use his own body as a pseudo-banjo, the rest of the clan immediately seizes upon the plan of eating Babs for lunch. At the movie's end, Banjo helps rescue the bunnies and ultimately moves to Acme Acres to attend the Looniversity himself. The Woodpile Possums also appear in the season 2 episode "Acme Cable TV" as a spoof of ''Series/TheBeverlyHillbillies'' opening theme, whilst Banjo himself shows up in the season 3 episode "Music Day", both in the wrap-around and in the sketch "The Horn Blows At Lunchtime".

* FatBastard: Most of the cannibalistic possums are quite rotund, bar one male and the young female, who're LeanAndMean instead.
* {{Foil}}: To the Boo Family. Both are {{Cannibal Clan}}s, but the Possums are dim-witted, savage, low-class and straight-forward predators, whilst the Boos act more refined and cultured, and so force their victims to go through a wedding ceremony first before eating them. Additionally, the Possums are mostly males, but the Boos are almost all female, and the Possums have a non-villainous clanmember, which the Boos don't.
* TheGrotesque: Pretty much all of the possums are hideous-looking creatures.
* HillbillyHorrors: A talking animals version, but they are dim-witted, ugly, swamp-dwelling hicks who try to kill and eat other sapients who wander their way. In "Acme Cable TV", Banjo explicitly calls his clan [[GettingCrapPastTheRadar "inbred"]] at one point.
* ShoutOut: The first encounter with Banjo is an extended reference to the famous Dueling Banjos scene from ''Film/{{Deliverance}}'' -- Banjo even looks something like the deformed banjo-playing kid from that move.
* TheSmurfettePrinciple: The Woodpile Possums consist of seven possums in total; Banjo, a diaper-wearing baby possum who could be either male or female, a family matriarch and patriarch, a female possum, and two male possums, meaning that there's either 4 males and 3 females or 5 males and 2 females in the clan.
* TokenHeroicOrc: Banjo, who actually rescues Buster & Babs in the finale of their storyline, assures them that he's not like the rest of his kinsfolk, and decides to abandon the swamp-dwelling cannibal lifestyle to get an education at the Looniversity.

!!The Boo Family

-->Voiced by: Creator/TressMacneille (Big Boo), Gail Matthius (Sissy boo), Creator/KathSoucie (Little Boo) and Sorrel Burke (Big Daddy Boo).

The second antagonistic group that Buster and Babs meet during the journey downriver as part of ''[[WesternAnimation/TinyToonAdventuresHowISpentMyVacation How I Spent My Vacation]]''; a crazy clan of carnivorous alligators consisting of three females -- Big Boo, Sissy Boo and Little Boo -- and their father, Daddy Boo, all of whom enjoy abducting and consuming unlucky travelers after forcing them to marry one (or more!) of the Boo sisters.

* BigThinShortTrio: Big Boo is the Big, Sissy Boo is the Thin, and Little Boo is the Short.
* CannibalClan: Well, the cartoon animal equivalent thereof, but they are a back-river dwelling clan of lunatics who enjoy feasting on their fellow sapients.
* ExoticExtendedMarriage: When the three Boo Sisters start squabbling over which of them will get to marry Buster, Big Daddy ends the fight by simply stating that they'll ''all'' marry him.
* FatBastard: Daddy Boo, the family patriarch and a hugely fat cannibal in the bargain.
* {{Foil}}: To the Possums introduced earlier. Both are {{Cannibal Clan}}s, but each is quite different to the other. The Boos consist of three females and one male, whilst the Possums consist of more males than females. The Possums are [[HillbillyHorrors stereotypical savage, deformed, killer hillbillies]], who simply leap on and attempt to devour whoever comes their way, whilst the Boos present an aristocratic mien and insist on doing things in the "well-mannered" way by wedding their victims before eating them. The Possums have a token non-villainous member, if the form of Banjo, whilst the Boos are all just straight-up villains. Finally, although both want to eat the bunnies, the Possums are more interested in eating Babs (perhaps because Buster's ability to make music with his body impresses them), whilst the Boos want to eat Buster.
* InterspeciesRomance: Zigzagged; the Boo Sisters are quite happy to flirt with and attempt to marry Buster, a male rabbit, despite being gators, but that's at least partially because they're going to eat him afterwards.
* LiteralManeater: As is made clear in their scenes, the Boo Sisters' modus operandi is to force unlucky men into marrying them, only to serve their "husband" up as the wedding feast after the ceremony is over.
* MarshmallowHell: The Boo Sisters relish smothering Buster in their bosoms when they can get ahold of him.
* NonMammalianMammaries: Despite being alligators, the Boo Sisters all sport very considerable cleavage.
* SouthernBelle: The Boo Sisters are all perfectly sweet Southern aristocrat girls... aside from the whole "eating their suitors" thing, of course. Complete with Southern Accents, of course.

!! Mr. Hitcher

-->Voiced by: Creator/RobPaulsen.

The BigBad of the direct-to-video movie, ''[[WesternAnimation/TinyToonAdventuresHowISpentMyVacation How I Spent My Vacation]]''. He is a chainsaw-weilding hitchhiker with a psychotic aversion to pork and duck.

* AxCrazy: Or more accurately, Chainsaw Crazy.
* BigBad: Of ''How I Spent My Vacation''. Though he doesn't appear until the second half of the movie, he still antagonized Plucky, Hamton, Buster, and Babs the most.
* DisneyVillainDeath: During his chase with Buster and Babs on a mine cart, he falls off a cliff and into a river. [[spoiler: Being an {{Expy}} of Jason Voorhees, he survives to chase Plucky in the closing song.]]
* {{Expy}}: Of Jason Voorhees.
* HockeyMaskAndChainsaw
* HostileHitchhiker: He tries to attack Plucky after Hamton's family picks him up.
* KarmaHoudini: Although he never actually kills any of his intended targets, Mr. Hitcher never gets arrested or killed for his violent behavior. [[spoiler:He even shows up at the end to continue chasing Plucky.]]

!! Duck Vader

-->Voiced by: Creator/JeffBergman

The BigBad of the episode, "A Quack in the Quarks", and a parody of Darth Vader from the ''Franchise/StarWars'' franchise.

* DarthVaderClone
* ElmuhFuddSyndwome: He speaks with a lisp similar to Elmer Fudd.
* HoistByHisOwnPetard: He is the FinalBoss of the ''[[VideoGame/TinyToonAdventuresBusterBustsLoose Buster Busts Loose]]'' video game, where he attempts to zap Buster with a giant laser. To defeat him, Buster must snatch the laser from him and zap him with it several times.
* MeanCharacterNiceActor: [[spoiler:At the end of the ''[[VideoGame/TinyToonAdventuresBusterBustsLoose Buster Busts Loose]]'' video game, during the ProsceniumReveal, he is revealed to be a costumed Plucky, which is odd, as he is a completely different character in the "A Quack in the Quarks" episode.]]

!! The Wolverine
-->Voiced by: Creator/FrankWelker.

The main antagonist of the episode, "Buster and the Wolverine", and a parody of the Wolf from Prokofiev's ''Music/PeterAndTheWolf''.

* BigBad: Of "Buster and the Wolverine".
* TheDragon: To Montana Max in the ''Babs' Big Break'' video game. In the game, he is Monty's bodyguard, has captured Shirley the Loon, and refuses to let her go until he is defeated in a battle.
* {{Expy}}: Of The Wolf from ''Peter and the Wolf''.
* SuddenlyVoiced: While he does mostly speak in grunts and roars, he has been known to speak normally on two occasions:
** In "Washingtoon", he becomes able to speak in complete sentences when the ACAFC Chairperson takes his tooniness away, rendering him sensitive to pain as a result.
** In the ''Babs' Big Break'' video game, he speaks fluently to the player when he explains that he has captured Shirley and is planning to eat her.

!! Adult Coalition Against Funny Cartoons Chairperson

-->Voiced by: Creator/TressMacNeille.

A woman representing an organization against funny cartoons.

* AccidentalMisnaming: She calls Plucky "Mr. Cluck" when he calls her to tell her that he wants to help her drain ACME Acres of its tooniness.
* AscendedExtra: She first appears in the "It's Buster Bunny Time" episode segment, "The Anvil Chorus" to rant about the violence, only to get hit by a falling anvil not long after. She later becomes the main antagonist of "Washingtoon".
* BigBad: Of "Washingtoon".
* CulturePolice: In "Washingtoon", she takes over ACME Acres with a device that strips toons of their tooniness so they could become bland, pro-social educators.
* FunWithAcronyms: She runs the '''A'''dult '''C'''oalition '''A'''gainst '''F'''unny '''C'''artoons. Don't even try pronouncing it.
* HeelFaceTurn: Towards the end of the episode, her Tooniness, which had been lost many years ago, emerges from the rubble of the Toon Logic Extractor after Buster's Tooniness destroys it. This gives her a sense of humor and she bounces off happily to Wackyland to live with Gogo Dodo and his friends.
* MoralGuardians: An in-universe example; she wants to cancel ''Tiny Toon Adventures'' and rid ACME Acres of cartoon violence, feeling it has a negative impact on children.

!! Fran and Edward

-->Voiced by: Valri Bromfield and Creator/JoeAlaskey, respectively.

Two network executives Babs worked for when she left Tiny Toons for "thirteensomething." They later appear in the Christmas special, overseeing Buster's production.

* {{Catchphrase}}: Fran to Edward on a regular basis:
-->'''Fran''': You are so lost, Edward.
-->'''Edward''': Yes dear.
** A variation occurs in the Christmas special.
--->'''Fran''' (''About Montana Max''): He is ''so'' lost, Edward.
--->'''Edward''': Yes he is, dear.
* CorruptCorporateExecutive: Subverted. They treat Babs fairly in "thirteensomething" and even renew her contract for the show (which admittedly was not something she wanted), and while Max does bribe them in the Christmas episode they promptly fire him and make Buster director again when they see how awful Max's ideas are. Edward even takes the money Max gave them and donates it to charity.
* TheDogBitesBack: Edward finally has enough of Fran's criticizing and tells her "No dear, YOU are lost!" She glomps him.
* EveryoneHasStandards: Montana Max originally started bribing them with lots of cash to take over Buster's Christmas special, but once they see how awful Max's directing is there's no amount of money he can bribe them with to make them think otherwise.
* HenpeckedHusband: Edward thanks to Fran, but whenever he does argue with her she considers it a turn on.
* MasculineGirlFeminineBoy: Edward is regularly impressed with little things Fran disagrees on, with Fran regularly telling him, "You are so lost.", and the few times he isn't impressed, his opinion is pushed aside by Fran's. That being said, he isn't afraid to stand up to Fran when she disagrees on his opinion of the plot twist Buster adds to ''Thirteensomething'' by posing as Cleveland, Alabaster's twin brother.
* TinyGuyHugeGirl: Fran practically dwarfs Edward in length and width.
* {{Tsundere}}: Fran to Edward.

!! The Original Looney Tunes

-->Voiced by: Creator/DonMessick, B.J. Ward, Creator/RobPaulsen, Desirée Goyette, and Robert Morse, respectively.

''WesternAnimation/BoskoTheTalkInkKid'' and his girlfriend Honey, as well as Foxy and Roxy and Goopy Geer. These guys were the original stars for the Warner Bros. cartoon studio in the early 30's, and after that time were abandoned and drifted into cartoon limbo for decades...until they were brought back for the episodes "Fields of Honey" and "Two-Tone Town", respectively.

* ArtEvolution: The characters (sans Goopy Geer) look ''nothing'' like they did in their original appearances, looking more like a combination of the 1930s rubberhose style with the '40s pears and spheres style, and with Bosko and Honey getting their species changed into dog-like designs. Although there's a good reason for this -- Bosko and Honey were originally caricatures of old time ministrel black people, and Foxy and Roxy were shameless copies of Mickey and Minnie Mouse. Goopy was never an ersatz of any character (not even of WesternAnimation/{{Goofy}}; that character first appeared a month after Goopy Geer made his debut) so he only recieved a mild redesign.
* ADayInTheLimelight: Both of the episodes they respectively appear in.
* PoorlyDisguisedPilot: Both episodes are clear forerunners to the Tiny Toons' SpiritualSuccessor, ''WesternAnimation/{{Animaniacs}}''. The characters' redesigns are even suspiciously similar to those of Yakko, Wakko and Dot.
