List of Animaniacs characters

The Warner Siblings (Animaniacs)

• Yakko – 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. He gets his name for his talkative nature being generalized as loquacious. As per his age and 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 – Wakko is the middle sibling, 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 accent inspired by the Beatles drummer, Ringo Starr.
• Dot – Dot is the youngest sibling at 10 years old, and the only sister. She is more easily relaxed than her brothers, but proves on numerous occasions that she can be just as wild as they are. She claims her full name is Princess Angelina Contessa Louisa Francesca Banana Fanna Bo Besca III; she also despises being referred to as "Dottie", threatening anyone who does so with death.

  Supporting characters

• Dr. Otto von Scratchansniff – A WB studio psychiatrist of Austrian descent 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 achieves his characteristic baldness—but then becomes fonder of and takes more responsibility for them as the series progresses, 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 – The curvy blonde WB studio nurse who various males—particularly the Warner Bros, Yakko and Wakko—fawn over. 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 – The dim-witted WB Studios security guard who is usually the one to get the Warner siblings recaptured, and to 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 Warners' 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 – The 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, as he has left his position at Warner Bros. sometime during the Warners' 22-year period of absence.
• Nora Rita Norita – 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 – 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.

  Pinky and the Brain

Supporting characters

• Billie – 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 – 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 – 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. In "Reichenbrain Falls", she disguises herself as Pinky an attempt to get Brain to reveal a code needed to trigger his latest scheme, but he is able to uncover her ruse. In "All's Fair in Love and Door", Pinky discovers that Brain created a virtual reality where he and Julia are a couple, which Brain made out of regret for what he did to the real Julia. The AI copy of her then turns on Brain after overhearing a private conversation between him and Pinky that leads to her realizing that she's not a real physical being. The AI Julia then attacks the two as a robot in the real world, but she gets defeated. Soon after, the real Julia discovers the AI Julia's damaged robot form, seemingly intending to make use of her AI self, though neither appear any further due to the revival ending after three seasons.
• Snowball – 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 which Pinky and Brain are sometimes forced to stop.
• Larry – 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 – A redheaded girl who became Pinky and the Brain's owner in Pinky, Elmyra & the Brain. She originated from Tiny Toon Adventures.
• Precious
• Pinky's Parents
• Brain's Parents
• Romy and Maurice LaMarche

  The Goodfeathers

Supporting characters

• The Godpigeon – An elderly anthropomorphic pigeon and parody of Vito Corleone in The Godfather who leads the crime family and shows up at different points to provide advice to the Goodfeathers on how get through a situation. He usually speaks in mock-Italian mumbling noises, and Bobby translates for him.
• The Girlfeathers - A trio of anthropomorphic doves and the Godfeathers' girlfriends.
• * Sasha - Squit's girlfriend and Pesto's equally hot-tempered sister. She is modeled on Lorraine Bracco's performance as Karen Friedman Hill in Goodfellas.
• * Lana - Bobby's girlfriend. She is a parody of Cathy Moriarty's character in Raging Bull.
• * Kiki - Pesto's girlfriend and a stereotypical dumb blonde.
• Pipsqueak – A tiny anthropomorphic great horned owl.
• Ma – A anthropomorphic dove and Pesto and Sasha's mother who lives in Miami Beach, Florida.
• Steven Seagull – An anthropomorphic seagull, who becomes the stepfather of Pesto and Sasha by marrying Ma. He is a parody of Steven Seagal.
