=== Li'l Sneezer[edit] ===
Li'l Sneezer (voiced by Kath Soucie), is based on the classic animated mouse Sniffles from the Looney Tunes shorts. However, his extremely talkative personality is based on Little Blabbermouse. He is a young, gray male mouse who wears a diaper. He is shown to be allergic to many things. His allergies trigger exaggerated, explosive, gale-forced sneezes capable of seriously damaging or destroying buildings, as Elmyra had the misfortune of finding out. He is the youngest of the students at Acme Looniversity, as he is the only one seen wearing diapers. Due to his small size, he sometimes spends time with other smaller students like Sweetie.
=== Arnold the Pit Bull[edit] ===
Arnold the Pit Bull (voiced by Rob Paulsen) is a white, muscular, male pit bull with a pair of black sunglasses, parodying Arnold Schwarzenegger. He is one of the few characters who does not attend Acme Looniversity and isn't based on an existing Warner Bros. character, though there is some connection between him and Hector the bulldog from the Sylvester and Tweety shorts. Arnold has various jobs, including lifeguard, doorman, zookeeper, security guard, bouncer, and gym owner. He hails from Romania, as mentioned in the episode "It's Buster Bunny Time", which explains his strong accent. His love interest is another white muscular pit bull named Arnolda.
=== Byron Basset[edit] ===
Byron Basset (voiced by Frank Welker) is a brown, black and white male basset hound, generally portrayed as being slow and lazy. He is based on Looney Tunes's many dog characters, specifically Barnyard Dawg. One sight gag involves him turning around: to do so, he pulls his head and tail inside the folds of his body, then pulls them out the other side. He is also shown to be capable of flight, as seen in the movie Tiny Toon Adventures: How I Spent My Vacation, using his stretchy skin to glide on a waft of air. Byron is sometimes shown as one of Elmyra's pets. His end tag is a simple "woof".
=== Fowlmouth[edit] ===
Fowlmouth (voiced by Rob Paulsen) is a young, white male rooster with a blue, short-sleeved shirt. He is based on Foghorn Leghorn, though he speaks in a New York accent instead of a Southern accent. Fowlmouth is shown to be very polite when calm but when his short temper is provoked, he launches into a bleeped-out swearing tirade. In his first appearance, he was even shown to pepper all of his sentences with profanity, but he curbs this when children are around. Other appearances show him using euphemismsinstead, likely due to Buster's efforts to train him out of swearing in the premiere episode. Fowlmouth's profane catchphrase is "dadgum". In Tiny Toon Adventures: How I Spent My Vacation, he annoys people in a theater by talking about the movie plotline.
=== Mary Melody[edit] ===
Mary Melody (voiced by Cindy McGee in her debut episode "Cross-Country Kitty," and Cree Summer in all other appearances) is a young, African-American girl. Her name is a pun on the Merrie Melodies series of Warner Brothers shorts. She may be based on Granny, as she is the human master of Furrball, but she is modeled on the one-shot character So White from the controversial Warner Bros. short "Coal Black and de Sebben Dwarfs". She attends Acme Looniversity with the other characters and sometimes hangs out with Babs, Shirley, and Fifi. Mary has a sweet disposition with almost everybody, unlike her human counterparts Montana Max and Elmyra Duff (also voiced by Cree Summer). Mary lives in an apartment building in the city of Acme Acres.
=== Bookworm[edit] ===
Bookworm is a green male worm with large glasses. He is based on the bookworm companion of Sniffles. He works at the Acme Looniversity library and is shown to be well-read and proficient on the computer. In some scenes, he is pursued by Sweetie. Bookworm does not speak; however, he does say something just before the football game in Buster Busts Loose on the SNES, though it is only on-screen text.
=== Concord Condor[edit] ===
Concord Condor (voiced by Rob Paulsen) is a young, purple male condor. He attends Acme Looniversity and lives in Acme Acres. He is based on Beaky Buzzard. Concord is shy and dimwitted, often ending sentences in "nope nope nope nope," or "yup yup yup yup." He lives at Acme Zoo, where he spends most of his time relaxing in his nest and watching TV. His first name is pronounced the same as the supersonic airliner, the Concorde, in spite of being spelled the same as the town in Massachusetts.
=== Barky Marky[edit] ===
Barky Marky (voiced by Frank Welker) is a young, brown, and tan male dog. He is based on Looney Tunes's many dog characters, specifically Marc Antony and Sam Sheepdog. Barky Marky is portrayed as a typical canine who loves to play fetch and various other sports and activities. Even though Barky starred in his very own short entitled "Go Fetch" with Elmyra Duff, and made many cameo appearances in other episodes, specials, and movies, Barky Marky was still mocked for his lack of appearances on the Saturday Night Livespoof Weekday Afternoon Live. When Buster Bunny is reading the news out loud from the viewers complaining about him not being in enough episodes, Babs Bunny, posing as a Tiny Toons casting director, asks "Who's Barky Marky?"	
=== Gogo Dodo[edit] ===
Gogo Dodo (voiced by Frank Welker) is a young green male dodo with blue shoes and a pink and purple umbrella sticking out from the top of his head. Gogo performs various bizarre sight gags and stunts. Unlike the other characters who attend Acme Looniversity, Gogo makes his home in the Daliesque realm known as Wackyland, a surreal place with constantly changing backgrounds. It is on the outskirts of the city of Acme Acres, which is the usual setting of Tiny Toon Adventures. Gogo is the only student related to one of the Looney Tunes characters—he is a relative of the Dodo bird in Porky in Wackyland, who was retroactively named Yoyo Dodo. Gogo's catchphrase is "It's been surreal!"
=== Furrball[edit] ===
Furrball (vocal effects provided by Frank Welker; Rob Paulsen provides his voice in "Cinemaniacs" and "Buster and the Wolverine" episodes) is a young, blue male cat with a hole in his right ear and a bandage on his tail. Furrball is usually depicted as living in a cardboard box in an alleyway, although sometimes he is shown as one of Elmyra's pets and briefly had a home with Mary Melody. He is a peaceful and innocent character, but he is also one of the most unfortunate characters in the show, since he is almost always chased, abused, or bullied, often by being squashed. For example, during the intro credits, he gets flattened by a falling upright piano to the lyric of "Furrball is unlucky", while peacefully sniffing a flower. He is less anthropomorphic in nature than the other animal characters, generally walking on all fours and almost always mute, except for making typical cat sounds; he is known to be mentored by Sylvester the Cat. Furrball is based on Penelope Pussycat and the Chuck Jones version of Sylvester, both of whom are silent. Furrball often chases Sweetie Pie, who is based on Tweety. In one speaking role ("Cinemaniacs"), he was voiced by Rob Paulsen in a mockup of Leonard McCoy from Star Trek. He also has another very brief speaking role in the episode "Buster and the Wolverine".
=== Sweetie Bird[edit] ===
Sweetie Bird (or Sweetie Pie) (voiced by Candi Milo, then Tessa Netting in the reboot) is a young pink female canary with a light blue ribbon bow in her plumage. She is based on the Bob Clampett version of Tweety Pie. Like her predecessor, she is colored pink and is devious around feline enemies like Furrball. Sweetie chases Bookworm (based on a nameless bookworm character in Chuck Jones's Sniffles the Mouse cartoons) with about the same success as Furrball. Though it is only seen in one episode, Sweetie, like Plucky, is also quite jealous of Buster and Babs's popularity and is the only character other than Plucky to openly speak up about it. In one scene, she was cared for by an eagle until he realized that she was too crazy and dangerous to be around. She sometimes switches from her babyish voice to a louder, more obnoxious voice.
=== Dizzy Devil[edit] ===
Dizzy Devil (voiced by Maurice LaMarche) is a young lavender male Tasmanian devil with a yellow propeller cap, as well as one pink eye and one green eye, and is also crosseyed. He is based on the Tasmanian Devil, and he spins around like a tornado and eats constantly like him. Also like Taz, his speech is generally monosyllabic or composed of random noises. Unlike Taz, he has no ears, horns, or tail. Dizzy is adored and sometimes accompanied by a trio of young ladies, who often make the other guys like Montana Max go crazy. Dizzy meets them in an episode where he fell in love with a little tornado, thinking that it is another Tasmanian Devil. When the tornado leaves the city, Dizzy becomes depressed, so the trio of young ladies take pity on him and decide to pet him.
=== Calamity Coyote[edit] ===
Calamity Coyote (voiced by Frank Welker) is a young, gray male coyote with pink sneakers; he is based on Wile E. Coyote. Calamity never speaks, instead communicating through noises and signs that he pulls out from behind his back. Calamity is also shown to be scientifically proficient, constructing random devices for the other characters. He pursues Little Beeper unsuccessfully. Like Wile E., Calamity's devices frequently malfunction. Calamity is less antagonistic than Wile E., preferring to work on his various inventions rather than chase Little Beeper.
=== Little Beeper[edit] ===
Little Beeper (voiced by Frank Welker) is a young roadrunner with red and orange feathers and blue sneakers. Much like his Looney Tunes counterpart, the Road Runner, Beeper spends most of his time outrunning and avoiding capture by Calamity Coyote. Unlike the Road Runner, Beeper can laugh and make other sounds, but he does not speak.	
 	
=== Hamton J. Pig[edit] ===
Hamton J. Pig (voiced by Don Messick in the TV series, Billy West in video games, also by David Errigo Jr.in the reboot) is a young pink male pig who wears blue overalls. Based on Porky Pig, Hamton's role in the series is as a straight man, often against Plucky Duck's antics. The only difference is that unlike his mentor Porky, Hamton never stutters. Hamton is an overeater who is obsessed with cleanliness. Billy West took over the role of Hamton in a few video games after Don Messick's death, including 1999's Tiny Toon Adventures: Toonenstein.
=== Shirley McLoon[edit] ===
Shirley "The Loon" McLoon (voiced by Gail Matthius) is a loon citizen of Acme Acres. She is based on Daffy Duck's main love interest, Melissa Duck. She speaks with a thick Valley girl accent. Although she seems reasonably intelligent, she is obsessed with superficial New Age paraphernalia. Her name is a pun on fellow New Age aficionado Shirley MacLaine, and she later appeared in an episode of Animaniacs, standing next to MacLaine. Most characters refer to her as "Shirley the Loon" rather than "Shirley McLoon". She appears not to notice the negative connotations of the nickname and often recites "Oh, what a loon I am" while meditating. Shirley is romantically pursued by Plucky Duck and Fowlmouth. Despite her annoyance with Plucky's flirtatious gestures, Shirley does seem to care for him and occasionally dates him. According to writer Andrew Stanton, She is the Girly Girl to Elmyra’s Tomboy because Elmyra is a perky, happy-go-lucky tomboy and Shirley is an intelligent Girly Girl. Shirley often hangs out with Babs and Fifi. She can tell fortunes, obtains psychokinetic powers, and is a skilled ballerina.
=== Fifi La Fume[edit] ===
Fifi La Fume (voiced by Kath Soucie) is a young, purple and white female skunk with a pink bow in her hair. Based on Pepé Le Pew, she shares his character traits of having a French accent and aggressively seeking romance, only to find the object of her affection is repulsed by her odor and aggressive advances. Unlike Pepé Le Pew, Fifi often takes being rejected to heart and cries over it. Fifi often unsuccessfully attempts to chase boys who have ended up with white stripes painted down their backs, such as Furrball, Calamity Coyote, and Little Beeper. Unlike Pepé Le Pew, Fifi does not mind if boys chase her. Some episodes downplayed her romantic life, and showed her doing random group activities with other characters. She lives in a striped 1959 Cadillac in a wrecking yard. 
=== Elmyra Duff[edit] ===
Elmyra Duff (voiced by Cree Summer) is a redheaded girl who wears a blue blouse, white skirt, black Mary Janes over white socks, and a blue bow with a skull at the center. Despite being based on Elmer Fudd – she has a similar face, her red hair has been revealed to be a wig on several occasions, and her last name backwards is a misspelled take on "Fudd" – she is the total opposite of him. Instead of hunting animals, she cares for them to smothering lengths and falls into the stereotype of the "spoiled and piercing-voiced girl."She is one of the few human characters in the series, and she attends Acme Looniversity with the animal characters, where she also serves as the nurse. In two episodes, Elmyra's family is shown, including her mother, inventor father, typical '90s teen sister, younger brother, super-strong baby brother, and a maid.
Elmyra was also featured as a co-protagonist and ally to Pinky and the Brain in a spin-off, Pinky, Elmyra & the Brain. Though initially claimed by Cree Summer to be removed from the show, Tiny Toons Looniversity.
=== Montana Max[edit] ===
Montana Max (voiced by Danny Cooksey), nicknamed "Monty", is a young brown-haired boy and the main antagonist. Based on Yosemite Sam, he is an evil, loud-mouthed, and money-hungry tycoon. Monty has an American location in his name and is often an enemy to Buster Bunny, much like Yosemite Sam is to Bugs Bunny. Like Elmyra, Monty is a human and attends Acme Looniversity. He is portrayed as a very wealthy and stubborn boy who lives in a mansion and doesn't have any siblings or friends. However, he does have a (rarely shown) sweet side and has been shown to have a good imagination. Elmyra likes Monty a lot, though he usually feels nothing but annoyance towards her. He was the very first villain of the series, as seen in the pilot episode.	
Flavio and Marita, also more commonly known as the Hip Hippos, are a wealthy, Spanish, anthropomorphic hippo couple voiced by Frank Welker and Tress MacNeille (singing voices done by Wendy Knudsen for Marita and Ray McLeod for Flavio).
=== Supporting characters[edit] ===
* Dr. Gina Embryo (voiced by Tress MacNeille) – A human zoologist who studies the Hip Hippos and tries in vain to protect them, a parody of both Joan Embery and Jane Goodall.
* The Maid (voiced by Tress MacNeille) - The Hip Hippos' anthropomorphic giraffe maid who appears in "La Behemoth".
* The Punishing Petersons (voiced by Jim Cummings and Tress MacNeille) - A super athletic and highly competitive couple, who first appears in "Amazing Gladiators" as competitors on the namesake show (a parody of American Gladiators).	
Minerva Mink is a curvy young anthropomorphic mink, voiced by Julie Brown, who was called Marilyn Mink in pre-production.
=== Supporting characters[edit] ===
* Newt (voiced by Arte Johnson) – A faithful anthropomorphic dachshund who appears in "Puttin' on the Blitz".
* Wilford B. Wolf (voiced by Peter Scolari) – An anthropomorphic nerdy wolf who becomes a handsome werewolf every full moon. His werewolf alter-ego is similar in appearance to a Chippendales dancer and very affectionate to Minerva. Minerva once asked him about his werewolf changes and when will the next full moon come, Wilford answers that it comes every 28 days, to which she replies, "Good things are worth waiting for	
 	
Katie Ka-Boom is a teenage girl voiced by Laura Mooney, who morphs into various violent, destructive monsters when things do not go her way. She lives with her parents and her little brother named Tinker. Writer Nicholas Hollander based Katie on his own daughter, who, at the time, was going through a similar tantrum phase.
In the reboot episode "Good Warner Hunting", Katie is seen with the previous cartoon characters and her appearance suggests that she is now an adult.
=== Supporting characters[edit] ===
* Tinker Ka-Boom (voiced by Justin Garms) – Katie's little brother, who is five years old and in kindergarten. He wears a blue shirt and red hat like Wakko.
* Mr. and Mrs. Ka-Boom (voiced by Rob Paulsen and Mary Gross respectively) – Katie's parents. Mr. Ka-Boom's voice and appearance are modeled after Jimmy Stewart.
* Jared (voiced by Eric Balfour) - Katie's boyfriend	
Buttons is a German Shepherd Dog who watches Mindy when her parents are away. He also has some rarely shown anthropomorphic traits. His vocal effects are provided by Frank Welker. Mindy, voiced by Nancy Cartwright, is a young girl who constantly wanders into trouble without even being aware of it. Buttons haplessly struggles with various dangers and narrowly rescues Mindy, only to be blamed and punished for her misbehavior. There is no consistency or continuity in the storytelling; most episodes each feature Mindy's family living in a different setting and portraying them as different sorts of people. In Animaniacs: Wakko's Wish, Buttons is rewarded with some good steak instead of being punished.
=== Supporting characters[edit] ===
* Mindy's Mother (voiced by Tress MacNeille) – In brief off-camera appearances, her face is never shown and she is usually called "Lady" by Mindy in the series; in Animaniacs: Wakko's Wish, Mindy finally calls her "Mom".
* Mindy's Father (voiced by Frank Welker) – His face is also never shown; Mindy usually calls him "Mr. Man".	
* Rita (voiced by Bernadette Peters) – A sarcastic, aloof and intelligent cat that sings. She also has various anthropomorphic traits.
* Runt (voiced by Frank Welker) – A dim-witted dog who thinks that Rita is also a dog like himself and who constantly uses the word "definitely" when speaking. This verbal tic, as well as Runt's speaking style, is a reference to Dustin Hoffman's character in Rain Man. He also has a few anthropomorphic traits, even though these are rarely shown.
=== Supporting characters[edit] ===
* Dr. Phrankenstein (voiced by Adrienne Alexander) – A stumpy female mad scientist, who appears in "Phranken-Runt".
* Scout (voiced by Frank Welker) – Dr. Phrankenstein's dog-like creation, who appears in "Phranken-Runt".
* Mr. Squeak – Dr. Phrankenstein's pet rat, who appears in "Phranken-Runt".
* Mrs. Mumphead (voiced by Paul Rugg) – An eccentric old lady, who appears in "No Place Like Homeless".
* Crackers (voiced by Frank Welker) – Mrs. Mumphead's pet parrot, who appears in "No Place Like Homeless".
* Kiki – An ill-tempered gorilla, who appears in "Kiki's Kitten".
* Mr. Politician (voiced by Frank Welker) – A parody of Ross Perot, who appears in "Icebreakers".
* Missy "Ma" McCoy (voiced by Tress MacNeille) – An elderly farm cat, who appears in "Up a Tree"	
* Slappy Squirrel (voiced by Sherri Stoner) – A female anthropomorphic squirrel and a grumpy old cartoon veteran, who lives in a tree with her nephew Skippy Squirrel. The music played in some of her segments is from Antonín Dvořák's "Humoresque No. 7".
* Skippy Squirrel (voiced by Nathan Ruegger) – An anthropomorphic squirrel and Slappy's grand-nephew, whose chipper personality is the opposite of his aunt's. His character varies from slightly naive to innocent to being a complicit partner of Slappy.	
* Walter Wolf (voiced by Frank Welker in his first appearance and Jess Harnell for the remainder of the series) – An anthropomorphic wolf and Slappy Squirrel's longtime nemesis. He is a parody of the Big Bad Wolf characters of Disney and Tex Avery fame.
* Stephen Wolf (voiced by John P. McCann) - An anthropomorphic wolf and Walter's grandson, who appears in "...And Justice For Slappy". In the episode, he acted as Walter's attorney as part of Walter's plot to finally turn the table on Slappy as revenge for years of torment by her by putting her on trial for supposedly "assaulting him with a intent to squash" (even though he was the one who assaulted her first). However, Walter's plans eventually fail when Slappy is found innocent. As a result, he brutally attacks his own grandson.
* Sid the Squid (voiced by Jack Burns) – An anthropomorphic squid villain similar to Chuck Jones' version of Daffy Duck.
* Beanie the Brain-Dead Bison (voiced by Avery Schreiber) – An anthropomorphic bison villain similar to Pete Puma.
* Stinkbomb D. Bassett (voiced by Jonathan Winters) – An anthropomorphic basset hound and foe of Slappy, who appears in "Smell Ya Later".
* Bumpo Bassett (voiced by Luke Ruegger) – An anthropomorphic basset hound and Stinkbomb's grandson, who also appears in "Smell Ya Later".
* Candie Chipmunk (voiced by Gail Matthius) – A female anthropomorphic chipmunk and Slappy's self-centered neighbour, who appears in "I Got Yer Can". An excerpt of the "Dance of the Reed Flutes", from Tchaikovsky's Nutcracker Suite, plays whenever she appears.
* Codger Eggbert (voiced by Chuck McCann in "Critical Condition" and Billy West in "Hurray for North Hollywood") – A parody of Roger Ebert.
* Lene Hisskill (voiced by Maurice LaMarche) – A parody of Gene Siskel, who appears in "Critical Condition".
* Doug the Dog (voiced by Frank Welker) – A large anthropomorphic bulldog villain, who appears in "Slappy Goes Walnuts".
* Vina Walleen (voiced by Tress MacNeille) – A female anthropomorphic deer and old friend of Slappy, who appears in "Bumbie's Mom".
* Daniel Boone (voiced by Jim Cummings) – The self-proclaimed "best frontiersman that ever lived", who appears in "Frontier Slappy".
* Duke (voiced by Corey Burton) – A school bully, who appears in "Bully for Skippy".
* Ms. Butley (voiced by Tress MacNeille) – Skippy's guidance counselor, who appears in "Bully for Skippy".
* Reef Blunt (voiced by Rob Paulsen) – Chairman of the Federal Television Agency, who appears in "Bully for Skippy". He wanted everyone involved in children's television to follow the new strict guidelines, which includes decreasing amounts of cartoon violence and increasing education for three hours each day, much to the misery of Yakko and Slappy.	
* The Godpigeon (voiced by Chick Vennera) – An anthropomorphic pigeon and parody of Vito Corleone in The Godfather. He is usually unintelligble and has to be translated by Bobby.
* The Girlfeathers are a trio of anthropomorphic doves and their girlfriends. Sasha (voiced by Tress MacNeille) is Squit's girlfriend and Pesto's equally hot-tempered sister. Lana (voiced by Gail Matthius) is Bobby's girlfriend, a parody of Cathy Moriarty's character in Raging Bull. Kiki (voiced by MacNeille), is Pesto's girlfriend and a stereotypical dumb blonde.
* Pipsqueak (voiced by Gabriel Luque) – A tiny anthropomorphic great horned owl.
* Ma (voiced by Lainie Kazan) – A anthropomorphic dove and Pesto and Sasha's mother, who lives in Miami Beach, Florida.
* Steven Seagull (voiced by David Kaufman) – A anthropomorphic seagull and Pesto and Sasha's stepfather, a parody of Steven Seagal.	
* Billie (voiced by Tress MacNeille) – A anthropomorphic female white mouse, who appeared in "The World Can Wait", "Brain Noir" and "You'll Never Eat Food Pellets In This Town Again!".
* Pharfignewton (voiced by Rob Paulsen and Frank Welker) – A female white racehorse who Pinky fawns over. Her name refers to Phar Lap, Fig Newtons and Fahrvergnügen, the last an advertising slogan used by Volkswagen. Unlike most other animal characters from Animaniacs, she does not have any anthropomorphic traits.
* Julia (voiced by Maria Bamford) – A female, genetically altered, anthropomorphic lab mouse and ex-wife of the Brain, who appears in the 2020 revival, first appearing in "Mousechurian Candidate". She was mutated by Brain using the DNA found on artifacts of past First Ladies of the United States to be his candidate for the position as he attempts to run for president. However, the public finds her more favorable and write her in instead, and Julia then defies Brain's schemes after finding them immoral. During a presidential debate in Nashua, New Hampshire, Brain attempts to control her using a neural implant in her left ear, but she overcomes his control through her own will. However, she cannot remove the malfunctioning device, which continuously gives her electric shocks. This gradually drives her insane, causing her to desire revenge and want to take over the world for herself.
* Snowball (voiced by Roddy McDowall) – An anthropomorphic lab hamster and Brain's former childhood friend-turned-rival who was also made intelligent by gene splicing and has a similar desire for world conquest (though his desire is far more malevolent than Brain's) which Pinky and Brain are sometimes forced to stop.
* Larry (voiced by Billy West) – An anthropomorphic white mouse created as a response to demands from Kids' WB executives to include additional characters on the show. His presence is sporadic, as the writers of the show believed that including an additional character would ruin the chemistry between Pinky and Brain, as they worked best as a comedy duo; thus a third character would, therefore, be out of place and unnecessary to the plot. To further drive this point home, Larry's first appearance was marked by a modified version of the theme song with the words "and Larry!" shoehorned in between existing lyrics. He is a caricature of Larry Fine of The Three Stooges fame; therefore, the episode's title is "Pinky and the Brain...and Larry". He later makes a brief cameo in the Animaniacs revival series segment "The Flawed Couple", appearing in the title sequence of Narfs, a parody of Cheers.
* Elmyra Duff (voiced by Cree Summer) – A redheaded girl who became Pinky and the Brain's owner in Pinky, Elmyra & the Brain. She originated from Tiny Toon Adventures.
* Precious (voiced by Nora Dunn)
* Pinky's Parents (voiced by Eric Idle)
* Brain's Parents (voiced by Ernest Borgnine and Tress MacNeille)
* Romy (voiced by Rob Paulsen (adult) and Maurice LaMarche (young)	
* Dr. Otto von Scratchansniff (voiced by Rob Paulsen) – A WB studio psychiatrist, who attempts to force the Warner siblings to be "less zany". He often loses patience with the Warner kids and has an outburst of frustration—his first chronological interaction with them sees him pulling out his hair until he achieved his characteristic baldness—but then becomes fonder of and takes more responsibility for them as the series progressed, occasionally acting as a father figure; the Warner siblings are clearly shown to be annoying him on purpose, but are also very fond of him.
* Hello Nurse (voiced by Tress MacNeille) – The curvy blonde WB studio nurse over whom various males—particularly the Warner Bros, Yakko and Wakko—fawn. Her appearance usually prompts the Warner brothers into affectionate greeting of "Hellooooooo, nurse!" occasionally accompanied by leaping into her arms or big kisses, although sometimes any number of all three WB siblings use the same gag on other characters. Hello Nurse appears in a few Slappy cartoons as a running gag. In Wakko's Wish, it is revealed that she has an IQ of 192, but is primarily respected for her looks and not her mind. The phrase "Hellooooooo, nurse!" was initially meant to be a catchphrase for Buster Bunny on Tiny Toon Adventures as a counterpart for Bugs Bunny's "Eh, what's up, Doc?", but the writers could not find an appropriate way for him to use the phrase organically; the phrase did not originate there, having been used decades earlier in vaudeville shows. Creator Tom Ruegger shared on Twitter that the character's name is Heloise Nerz and she has German heritage. The era of the revival would deem Hello Nurse inappropriate, and so she is fully absent, with Dr. Scratchansniff providing the in-universe explanation of her joining Doctors Without Borders in the intervening two decades.
* Ralph T. Guard (voiced by Frank Welker) – A dim-witted WB Studios security guard who is usually the one to recapture the Warner siblings and confine them to the Warner Bros. tower. He first appeared in Tiny Toon Adventures as the Fat Guard. Despite retaining his stupidity in the revival, he takes advantage of the Warner's lack of 21st century technology to contain them briefly. In the season 2 finale, he is revealed to be related to Nora Rita Norita and his real name is Ralphnazo.
* Thaddeus Plotz (voiced by Frank Welker) – A squat, hot-tempered, money-grubbing CEO of Warner Bros., whose portrait is a prominent decoration of the CEO's office. He is not present in the reboot (except in the two-part "Wakkiver Twist"), as he has left his position at Warner Bros. sometime during the Warners' 22-year period of absence.
* Nora Rita Norita (voiced by Stephanie Escajeda) – Plotz's successor in the revival. Though as stern and short-tempered as Plotz, she takes the Warners' zaniness more passively; she is also obsessed with her health so as to maintain her slender frame.
* Nils Neidhart (voiced by Fred Tatasciore) – An immensely muscular, narcissistic, and vindictive Liechtensteiner athlete with a massive ego. He prides himself on his muscles and laughs off those he assumes to be weaker than him. However, after the Warners outsmart him, he literally ends up trapped in Hell.	
 	
* Yakko (voiced by Rob Paulsen, occasional singing voice provided by Gabriel Mann in reboot) – Yakko is the wise-cracking, smart-and-fast-talking, oldest sibling—who usually acts as the leader of the trio. He's the oldest sibling, at 14-years-old. He gets his name for his talkative nature being generalized as loquacious. As per his age and consequent obsession with girls, Yakko is responsible for most of the show's adult humor. He is inspired by Tom Ruegger's son Nathan, who also voices Skippy Squirrel.
* Wakko (voiced by Jess Harnell, belched by Maurice LaMarche, occasional singing voice provided by Brock Baker in reboot) – Wakko is the middle sibling, at 11-years-old, who has a huge appetite and magical "gag bag" full of tricks. He earns his name for being the most outrageous in physical comedy—and supposedly the least intelligent—though Yakko has claimed it to be "middle kid syndrome" in the episode "Survey Ladies". He also has a Scouse/Liverpool dialect inspired by The Beatles.
* Dot (voiced by Tress MacNeille, occasional singing voice provided by Missi Hale in reboot) – Dot is the youngest sibling at 10-years-old, and only sister. She is more easily relaxed than her brothers, but proves on numerous occasions

Main article: SpongeBob’s Multiverse: The Movie
SpongeBob’s Multiverse: The Movie was produced at Dr. D Studios and released on December 16, 2023. The cast reprised their roles for the sequel. Dolci was set to reprise her role and begin recording sometime in 2023, but was replaced by Nikki Herring after Dolci died from colon cancer on March 31, 2009. Loud House and Casagrandes are joined the movie respectively.
