"I am a mind — a Brain! I am the Brain!"
A genetically altered lab mouse with a large head who plans to - you guessed it - Take Over the World.
Tropes associated with The Brain:
  • Affably Evil: The Brain intends to rule benevolently for the good of all, but he does intend to become the unquestioned dictator of the Earth. In person, he's amiable enough (unless you're Pinky and you've just said something so stupid that the only proper criticism is a sharp smack.)
  • Anti-Hero: Brain is constantly trying to take over the world hardly heroic but he is good-natured (when not hurting Pinky) and truly believes that the world would be a better, happier place if he was in charge; this is justified by portraying real world's leaders as either egotistic, incompetent or plain crazy (or all at once). Also compare to his archrival Snowball, a sadistic villain whom Brain believed would destroy the world if he ruled it.
  • Anti-Villain: If you interpret him as a Villain Protagonist, though he really blurs the line between this and Anti-Hero. After all, the rest of the world is portrayed as so messed up and idiotic, him taking it over might actually lead to some form of utopia.
  • Are You Pondering What I'm Pondering?: I think so Trope Namer, but what does having a TvTropes article have to do with taking over the world?
  • Awesomeness by Analysis: You wouldn't think it by looking at him, but if a physical action or sport can be reduced down to physics/mathematics, Brain can do it flawlessly.
  • Bad "Bad Acting": Doesn't act so much as read his lines. His physical acting is just fine though - in "Brain's Song", he bounces a lemon-football around like a basketball during a live broadcast, and in "Cinebrainia" he essentially becomes a silent-film comedy actor this way.
  • Berserk Button: Downplayed in the sense that he doesn't go blind with rage, but there are two things that he will give top priority to - saving Pinky, and stopping Snowball.
  • Big Guy, Little Guy: The Little Guy to Pinky's Big Guy. Brain's not any weaker than Pinky though, and gives him credit where it's due.
  • Big "YES!": Essentially what one of his Catch Phrases is.
  • Break the Haughty: This Old Mouse.
  • Cartoony Tail: He has a tail like a real mouse, except it is kinked in a way that it looks like stair steps.
  • Catch Phrase:
  • City Mouse: Becomes The Load in outdoor and non-technical situations.
  • The Comically Serious: He can provide some laughs solely because of his stoic personality and having to deal with Pinky's dim-witted antics.
  • Creative Sterility: Seems to be a pet worry of his, bordering on Adult Fear. A couple of episodes focus on him worrying about how he can't come up with a new plan.
  • Deadpan Snarker: Seems he can't tell a normal joke though.
  • The Determinator: Tonight's plan failed? Start planning for tomorrow night. Repeat as needed.
  • Ditzy Genius: His plans are quite brilliant, but lack common sense.
  • Evil Genius: Averted, in a couple of ways - he is a genius, but Brain works for himself and was never particularly evil (he'll take direct action against actual evil) - but we don't have "Anti-hero Genius" as a trope yet.
  • Even Evil Has Standards:
    • His refusal to sell his soul for world domination in the Halloween Special. Usually an aversion, since he was never particularly evil to being with, and has enough scruples that he doesn't need Pinky to be a Morality Pet... most of the time.
    • One Very Special Episode against smoking has Brain playing Brainy The Elf, a spokesman for the tobacco industry, who use him as a mascot to get children to smoke. While he initially planned to put an additive in the tobacco as part of a plan to take over the world, he has a My God, What Have I Done? when he sees children about to start smoking, and turns against the tobacco industry.
  • Fatal Flaw: His lack of common sense. He has a few other glaring flaws, but this is what kills the nightly plan the most.
  • Four Legs Good, Two Legs Better: Walks and runs upright as a rule, even in the mouse wheel.
  • Freudian Excuse:
    • Being taken from his home and family when he was younger. Where were they living? A can with a globe (ie, the world) on it.
    • As a lab mouse, he's subject to testing; in "Where No Mouse Has Gone Before" at least, he holds a mild grudge over this.
    • It is suggested in "Project: B.R.A.I.N." that his desire to take over the world stems from his shame at never getting a chance to show the research scientists his newfound intellect.
  • Friendly Enemy: At least tries to be this to Snowball. It never works though.
  • Gadgeteer Genius: Brain's strongest suit. Quite often, the gadget or means to world domination is assumed to be an automatic success, and their 'twilight campaign' is typically the duo filling in a minor cog in the plan. However, it only applies to gadgets - take away his lab access, and he's completely lost.
  • Glad I Thought of It: Averted...? Though he will criticize the original comment as being unhelpful or irrelevant, quite a few plans are Brain's extrapolation(s) of something Pinky said, and he's more than happy to dole out credit for it.
  • Guile Hero: ...Hero might be pushing it a little, but he shows a clear preference for plans involving as little physical violence as possible, with (temporary) Mind Control and other forms of influence being favorites.
  • Grumpy Bear: In contrast to the cheerful Pinky.
  • Heterosexual Life-Partners: With Pinky, and he knows it.
  • Hidden Heart of Gold: It has been proven on numerous occasions that behind the megalomaniac outer layer lies a complete softy who cares deeply about the ones he loves, especially Pinky. The Christmas Special has to be the best example of his sweeter side.
  • Hoist by His Own Petard: The nightly plan usually fails because something he did boomerangs on him, such as trusting Pinky with a crucial part of the plan (more common early on), or some minor detail turns out to be a lynchpin. Sometimes it's not even Pinky's incompetence but Brain's reaction to it that wrecks his plans.
  • Indy Ploy: Averted. Brain's not all that good at dealing with a Spanner in the Works he didn't account for (separate from his lack of common sense), though this is due to an element he couldn't have predicted as often as it is just him dismissing something as irrelevant. In some cases, the plan gets as far as it does on sheer dumb luck.
  • Insufferable Genius: He is usually condescending to everyone. Although he's pretty tolerable compared to Snowball...
  • Iron Butt Monkey: Usually gets it worse than Pinky.
  • Jerk with a Heart of Gold: It's implied that he does have a small soft spot for Pinky deep down. And by 'implied', we mean 'all but publicly stated with a megaphone from the rooftops'. (It's most obvious when he thinks he might have accidentally hurt or killed Pinky through a device.) Multiple times he has stated his conquests as "our", and though he repeatedly snarks at Pinky he would go out of his way to help him, even if it means aborting every single plan.
  • Kavorka Man: Has no trouble attracting women when playing a human.
  • Large Ham: His voice actor described Brain as "65% Orson Welles, 35% Vincent Price."
  • Laughably Evil: To a large extent, even though he's The Comically Serious. To quote him, "I am not devoid of humor."
  • Meaningful Rename: Whatever his name was before, he goes by 'Brain' now. In the Italian dub, his name is "Prof" (short for professor).
  • Mobile-Suit Human: His mech suit is a human body...yet has no head.
  • Noble Demon: Wants to conquer the world to make it a place of kindness, equality and happiness for all.
  • No Celebrities Were Harmed:
  • Paper-Thin Disguise: When not using a mech suit as part of it, a lot of his human disguises are just himself with a wig. Even with the suits, the head is just him with a wig.
  • Parental Abandonment: One episode gave it as his Freudian Excuse. He meets them again in another episode; it doesn't exactly work out.
  • Pragmatic Villainy: In "A Meticulous Analysis of History", Brain espouses the view that historical rulers like Atilla The Hun and Caligula were thwarted by their own senseless brutality and warmongering, which is part of the reason why his own plans for world domination are almost always nonviolent.
  • Sarcastic Confession: Quite often, Brain will be forthright with people that he and Pinky are lab mice scheming to take over the world. Whoever he says this to thinks he's just joking around (and that's probably what he intends).
  • Sesquipedalian Loquaciousness: He can speak in layman's terms when he wants to (he switches over when dealing with people as part of the nightly plan), and Pinky understands him just fine most of the time. It's only gotten in the way of a plan when he tried to be a stand-up comedian - even then, he became popular as a highbrow insult comic.
  • Shorter Means Smarter: He and Pinky provide the page image. Even though they're lab rats and already pretty small by default, Brain is shorter than Pinky, who is a Cloudcuckoolander.
  • Sophisticated as Hell: He doesn't dabble in this too often, but it's there. "Opportunity Knox" provides this little gem when they take the Lab's van:
    Brain: Now Pinky, let us, in their vernacular, take this hog out on the road and show who's boss.
  • Spell My Name with a "The": 'The Brain', though in practice it's more of a 'full name' thing and he's not particularly insistent about it.
  • Take Over the World: He tries to, but always fails.
  • Technical Pacifist: There's any number of explanations for it, but Brain's plans rarely involve direct physical harm for anyone, even when that would greatly simplify things.
  • TV Genius: Averted. Though he's a brilliant engineer and scientist, he clearly has social skills (as well as a low tolerance for stupidity), and is sometimes seen studying.
  • Villain Protagonist: Could be interpreted this way, since his goal after all is world domination, though he's rarely out-and-out villainous.
  • Villains Never Lie: Parodied. Whenever Brain uses his mech suit and is asked why his head looks like a mouse, instead of coming up with an excuse (i.e. skin condition), he outright tells them the truth and they laugh it off.
  • Vitriolic Best Buds: Brain supplies all the vitriol, Pinky cheerfully thinks (rightly) that they're best buds.
  • Well-Intentioned Extremist:
    • It's not often you get a character who wants to Take Over the World so he can change it for the better, but there you go.
    • This was a bit of Character Development on Brain's part; the notion of making the world better was a result of events in the episode "Megalomaniacs Anonymous"...and even then, he's still doing it just a little for his own ego.
    • Even before that, there's every indication that he plans to rule the world far more benevolently than Snowball.
    • There are even quite a few implications that if he succeeded the world actually would be better off — in the Freakazoid! episode "Freakazoid is History," Freakazoid inadvertedly changes history and finds himself in a world where the Brain is president of the United States and the world is better off for it — among other things, cold fusion works and Sharon Stone is a good actress.
  • Workaholic: The other side of being a Determinator, and occasionally to an uncomfortable degree. ("This Old Mouse" points out that he's around 2 years old, and can expect to reach 4.)

     Pinky 
Voiced by: Rob Paulsen (English), Hideyuki Umezu (Japanese), Frank Carreño (Latin American Spanish)
http://static.tvtropes.org/pmwiki/pub/images/Pinky08_8.jpg
Another genetically engineered lab mouse: the Brain's closest friend, devoted assistant and part-time Spanner in the Works.
Tropes associated with Pinky:
  • Adaptational Jerkass: He noticeably shows more of a jerkish side to him in Pinky, Elmyra & the Brain. Lampshaded by the Brain in "My Fair Brainy".
    Brain: "You used to be a hindrance. Now you're a hindrance with an attitude."
  • Adorkable: He's a complete and utter goofball and it just makes him look all the more lovable.
  • Anti-Hero: An example of Classical Anti-Hero.
  • Anti-Villain: The only reason he's a villain at all is because he helps Brain.
  • Attention Deficit... Ooh, Shiny!: Much more common earlier on, but continues to play a large role in his side of the 'Are You Pondering What I'm Pondering?' exchange, apparently.
  • Bad "Bad Acting": Not averted so much as downplayed - he's better with a role of the two. "Brain's Song" even has him juggling two roles, narrator, stagehand, and carpenter duties.
  • Big Guy, Little Guy: Big Guy to Brain's Little Guy. Not any stronger than Brain, though.
  • Break the Cutie: The Christmas episode, The Halloween Episode, That Smarts and The Pink Candidate to name a few episodes. He can easily go from Plucky Comic Relief to Woobie under the right conditions.
  • Bumbling Sidekick: Though Brain clearly trusts him as an assistant, and they both think of it as a partnership/friendship anyway.
  • Catchphrase:
  • Cloudcuckoolander: In particular, he has a tendency to bring up celebrities at random and he always replies to Brain's statements of "Are you pondering what I'm pondering" with a completely irrelevant question.
  • Crouching Moron, Hidden Badass: While he may be a massive Cloudcuckoolander, when he gets his act together, he can come up with plans to take over the world that actually WORK.
  • The Cutie: In contrast to Brain, he's usually cheerful and lovable.
  • A Dog Named "Dog": The less obvious version - "pinkie" is a term for a newborn mouse (or other rodent), due to their lack of fur at birth.
  • The Dragon: Generally The Lancer, as his Cloudcuckoolander status makes him a less than useful Dragon.
  • Dumbass Has a Point: Often thinks to ask logical questions about the logistics of a plan. Brain will usually have thought of that himself, but props to Pinky for not needing to be prompted.
  • Dumb Is Good: Though, when events conspire to make him 'smarter' than usual, he doesn't get any less good.
  • First-Person Perspective: One episode is done entirely from Pinky's literal point of view, revealing that Pinky's flights of fancy take on literal form in his eyes (for instance, Pinky ruminates about hippos when listening to Brain. Brain turns into a hippo). Capped by a first-person perspective view of what it is like to be blasted out of the Space Needle.
  • Four Legs Good, Two Legs Better: Usually walks upright, but runs on all fours in the mouse wheel.
  • Genius Ditz: The theme song doesn't specify which one of them is the genius or insane... But in a more literal sense, Pinky's wide-ranging knowledge of pop culture (current and past) comes in handy from time to time - and he supplies them with no hesitation whatsoever. It's worth noting that, by mouse standards, Pinky is genuinely a genius: he's capable of speech, tool use, and higher-level reasoning. It's just that, by human standards (to say nothing of the Brain's standards), he's kind of a dim bulb.
  • Heterosexual Life-Partners: With Brain. They're rarely seen apart and both have been shown to be devastated if one were to leave or betray the other.
  • Hidden Depths:
    • Most of the time he's goofy and hyperactive, but has a strong moral compass that shows on occasion. Particularly when he became president of the U.S for one episode and turned Brain down when he tried to get him to abuse some of his new powers because "it would go against everything I've come to stand for."
    • Besides that, while he doesn't have Brain's sheer intelligence, he is still keenly observant and humanistic, and by far the more grounded of the two.
    • You wouldn't think being easygoing and adaptable would ever be useful, but it saves their lives in "Welcome to the Jungle" - Pinky manages to come up with stone age-level solutions to being trapped outside, while Brain is reduced to complete reliance.
  • Indy Ploy: Pinky's fast talking has been the only thing keeping the plan going on many, many occasions.
  • Interspecies Romance: With Pharfignewton (a horse), of course, but also with a sea lion and a pig in other episodes (unsuccessfully).
  • Iron Butt Monkey: Of course, Pinky doesn't really mind when Brain bops him on the head, so perhaps he's okay with it.
  • Keet: He's a very hyperactive mouse.
  • Kindhearted Simpleton: Usually goofy and scatter-brained, but certainly nicer and happier than the Brain.
  • Mad Libs Catchphrase: "I think so Brain, but [*improvises idea that has nothing to do with taking over the world*]" after Brain's Are You Pondering What I'm Pondering?.
  • The Millstone:
    • On occasion, though Brain's plans tend to fall apart without outside help. Early on in the Animaniacs segments, he tended to be the latter far more often; by the time of the series, he's rarely even The Load.
    • Brain at one point makes a calculation that it's always Pinky's fault that his schemes fail, so he uses an intelligence-enhancing device to make Pinky smarter. Pinky uses this newfound intellect to point out that it's Brain's nonsensical plans that are doomed to fail in the first place.
  • Minion with an F in Evil: He's just too ditzy and sweethearted to realize that hanging around someone who wants to Take Over the World doesn't put you on the side of good.
  • Morality Pet: On the rare occasions Brain's megalomania gets the better of him.
  • Nice Mice: Between the two, he balances them out to this.
  • Noble Demon: Downplayed. His demeanor isn't evil to begin with.
  • Plucky Comic Relief: He provides comic relief with his occasionally random comments.
  • Simpleton Voice: His voice is very goofy-sounding and matches his dim-witted nature.
  • Smarter Than You Look: There are hints that Pinky is actually very intelligent, the genius in the opening theme song, but his poor connection with reality and the fact that he's quite content with his lot in life hides it too well.
  • Tender Tears: Despite his cheerful personality, he cries fairly easily.
  • Too Dumb to Live: In the Animaniacs Stew episode "Pinky And The Cat", he gets devoured by Rita and enjoys it!
  • Too Kinky to Torture: "This is more fun than the coat-me-in-peanut-butter-and-shove-me-in-the-anthill game!"
  • Undying Loyalty: To Brain, for the most part.
  • Verbal Tic: Narf! Zort! Egad! Poit! Troz!
  • Villain Protagonist: Downplayed - he's villainous only by association.
  • Vocal Evolution: Pinky's speech impediment is more pronounced in the earliest segments. His voice is also a notch lower in the earlier Animaniacs segments.
  • The Watson: Grows into this as the show progresses. Brain is aware of this, and will occasionally rework the plan based on Pinky's observations.
  • Wholesome Crossdresser: He sometimes dresses as a woman as part of Brain's plans.

Other Characters

     Snowball 
Voiced by: Roddy Mc Dowall
http://static.tvtropes.org/pmwiki/pub/images/Snowball_5804.jpg
A hamster who was put through the same gene splicer as the mice and also schemes to Take Over the World, but does not intend on making it a better place like Brain would. As such, he is The Rival to the Brain. Was eventually changed back to an ordinary hamster in his last appearance.
Tropes associated with Snowball:
  • Always Someone Better: He's actually smarter and more efficient than Brain. He also doesn't need a sidekick, making him much more dangerous.
  • Brought Down to Normal: His final appearance has him turned back into a normal hamster.
  • The Caligula: It's suggested that Brain doesn't want Snowball to win because he's insane and that the world under his rule would fall into chaos.
  • Evil Brit: He was voiced by Roddy McDowall after all.
  • Evil Counterpart: To Brain, and evil enough that Brain will drop everything to stop him.
  • Evil Former Friend: He and Brain were friends before their intellects were enhanced.
  • Evil Genius: He's a highly intelligent mastermind and is much less scrupulous than the well-intentioned Brain.
  • Faux Affably Evil: He may act sophisticated and polite, but he's much worse than Brain.
  • Fluffy the Terrible: Snowball isn't a very scary-sounding name, but he is still a force to be reckoned with.
  • From Nobody to Nightmare: From a harmless hamster to Brain's rival in achieving world domination.
  • Killer Rabbit: He may be a hamster, but he isn't to be underestimated.
  • Knight of Cerebus: Snowball-centric episodes are always darker.
  • Mobile-Suit Human: Like the Brain, he also has a human mech, although he has a fully working head.
  • Perpetual Frowner: He rarely smiles.
  • Rival Turned Evil: When he and Brain became highly intelligent, they turned against one another because of a disagreement on which of them should take over the world.
  • Sanity Slippage: He appears to get more and more unhinged every time he comes back to battle Brain again.
  • Sesquipedalian Loquaciousness: Like Brain, he has a large vocabulary.

     Billie 
Voiced by: Tress MacNeille
http://static.tvtropes.org/pmwiki/pub/images/Pinky_and_the_brain_billie_8164.png
Another genetically altered lab mouse that Brain sometimes romantically pursued, despite her being as ditzy as Pinky. (Does This Remind You of Anything?)
Tropes associated with Billie:
  • Abhorrent Admirer: She becomes this towards Pinky in "Brain Noir". After Billie reveals that she loves Pinky rather than Brain or Snowball, Pinky himself is rather disturbed by Billie's advances and runs for it after she kisses him.
  • Distaff Counterpart: She's basically a female Pinky.
  • Genius Ditz: Her intelligence is about as high as Pinky's, but her vocabulary expands greatly after receiving electric shocks.
  • Love Dodecahedron: Between her, Brain, Pinky, Pharfignewton and Snowball. Specifically, both Brain and Snowball love her, but she has a crush on Pinky, who in turn is in love with Pharfignewton.
  • Sesquipedalian Loquaciousness: Speaks with much less simplistic terms after being subjected to electric shocks.

     Pharfignewton 

A grey and white race mare (female horse) whom Pinky fell in love with in the segment "The Kentucky Derby". She reciprocates his feelings, but sadly, they come from different worlds... not to mention different biological orders. The relationship between them obviously disgusts Brain.
Tropes associated with Pharfignewton:

     Roman Numeral 1 "Romy" 
Voiced by: Maurice LaMarche (as an infant), Rob Paulsen (as an adult)
http://static.tvtropes.org/pmwiki/pub/images/Romy_5894.jpg
A clone of both Brain and Pinky created from their combined DNA. (Does This Remind You of Anything?)
Tropes associated with Romy:
  • Cloning Blues: He is cloned from Pinky and Brain and just wants to be his own man.
  • Deadpan Snarker: He makes a few sarcastic remarks, particularly about Pinky and Brain's arguments and quarrels.
  • Does This Remind You of Anything?: Romy's creation is played similarly to a baby being born in addition to Brain and Pinky's disagreements on raising him being reminiscent of dysfunctional parents.
  • Interspecies Romance: He ends up in a relationship with Pat "the Bunny" (a human).
  • "It" Is Dehumanizing: While the ethical problems it raises aren't addressed, Brain constantly refers to Roman Numeral 1 as "it" while he is still a baby.
  • Mix-and-Match Man: He looks like a cross between Pinky and Brain.

     Brain's Parents 
Voiced by: Ernest Borgnine and Tress MacNeille


Tropes:
  • I Want Grandkids: Brain's mother at one point chides her son for not giving her grandchildren.
  • Jerk with a Heart of Gold: They do nothing but berate Brain for being untidy after gaining the ability to speak and threaten him whenever he tries to get a word in edgewise, but after they are sent away at the end of the episode, Brain mentions that his parents invited him and Pinky over for Thanksgiving, hinting that they care about their son at least a little bit.
  • Uplifted Animal: They are ordinary mice at first, but gain human-like posture and speech after Brain equips them with devices enabling them to talk.

     Pinky's Parents 
Voiced by: Eric Idle


Tropes:

     Pinky's "Sister" 


Tropes:

     Larry 
Voiced by: Billy West
http://static.tvtropes.org/pmwiki/pub/images/larry3.jpg
"Hi there! I'm the one named Larry."
A dopey chubby mouse with frizzy hair that sticks out in the sides like Larry Fine of the Three Stooges. He accompanied the duo during one of their schemes, doing little except constantly introducing himself and providing useless observations. Eventually, Brain tires of him and tells him to leave. He later joins up with Paul Simon.


Tropes associated with Larry:
  • Biting-the-Hand Humor: The entire reason for his existence. Larry was created in response to the network's request that Pinky and the Brain be joined by a third character. Naturally, the writers thought this to be completely pointless, so they created Larry to demonstrate just how pointless a third character would be. However, the network eventually won out, with Elmyra of Tiny Toon Adventures being shoehorned into the show in Pinky, Elmyra & the Brain.
  • Captain Ersatz: Of Larry, naturally.
  • Catch Phrase: "Hi there!", "Hello!", and "I'm Larry!"
  • Flat Character: Deliberately so. He contributes absolutely nothing to the episode's plot, and doesn't do anything except introduce himself and point out that he's Larry. He's merely there to demonstrate just how useless adding a third wheel to Pinky and the Brain would be.
  • Furry Baldness: He has tufts of hair around his head implying baldness even though his body's covered in white fur like Brain and Pinky.
  • Here We Go Again: Finally, Brain managed to get rid of "Larry", and be just a duo with Pinky again. Now it's time to take over the world, without Larry... and the scientist opens the cage and introduces a new mouse, Zeppo. And Here We Go Again
  • My Friends... and Zoidberg:
    Brain: Tonight's plan is my masterpiece, Pinky... and, uh, Larry.
    Larry: Hi there!
    Pinky: I like the lines, Brain, and, uh, Larry
    Larry: I'm Larry!
    (and it goes on the whole episode like that)
  • No Celebrities Were Harmed: Larry from The Three Stooges. There's even a point in the episode where Brain gets a piece of wallpaper stuck to his head that looks like Moe's bowl-cut hair.
  • Remember the New Guy: The one episode featuring him treats him as if he always was part of the main cast.
  • Shoo Out the New Guy:
    Brain: It's all about teamwork. That special chemistry. The Yin and the Yang.
    Larry: And Larry!
    Brain: No, that's it! It's just yin and yang! There shouldn't be a Larry!
    Pinky: Zort! Am I the yin or the yang?
    Brain: I don't know, Pinky. But he is definitely the Larry!

     Trudy 
Voiced by: Pamela Hayden
A black-haired mouse from the black and white Pinky and the Brain episode, "The Third Mouse."

Tropes:

     Mousey Galore 
Voiced by: Diane Michelle
http://static.tvtropes.org/pmwiki/pub/images/Pinky_and_the_Brain_Mousey_Galore_4897.jpg
Russian lab mouse and rival to Pinky and the Brain in "To Russia With Lab Mice".
Tropes:

     Dr. Mordough 
Voiced by: Jeff Bennett
http://static.tvtropes.org/pmwiki/pub/images/DrMordough_3222b_4157.png
The scientist who built the gene splicer that turned Brain, Pinky, and Snowball into their anthropomorphic forms. Appears only in part 3 of "Brainwashed".
Tropes associated with Dr. Mordough:

     The Evil Clown 
Voiced by: Corey Burton
http://static.tvtropes.org/pmwiki/pub/images/EvilClown_2_4724.png
Precious's confidant.
Tropes associated with The Evil Clown:

     Precious 
Voiced by: Nora Dunn
http://static.tvtropes.org/pmwiki/pub/images/PreciousTheCat_5001.jpg
Dr. Mordough's cat who was the Diabolical Mastermind of the scheme the mice had to foil in "Brainwashed". Like the mice, she too gained brainpower from the gene splicer, but lost her feline beauty and swore vengeance on humanity as a result.
Tropes associated with Precious:
  • Cats Are Mean: Though originally averted.
  • Freudian Excuse: She wants to destroy the world because her increased intelligence robbed her of her good looks and therefore made her an outcast.
  • Omnicidal Maniac: Unlike Brain or Snowball, she just wants to destroy humanity and bring everything to ruin out of anger and has no intention of ruling anything.
  • Partially Civilized Animal: While she is highly intelligent, she still is susceptible to common feline instincts such as playing with small shiny objects.
  • Roaring Rampage of Revenge: She wants to annihilate civilization just because she's not adorable anymore.

     Zalgar 
Voiced by: Jeff Bennett
A humanoid alien who scouts planets to eat the being with the highest intellect's brain, he attempts to steal Brain's after sending him an email promising to help him take over the world, after his defeat he decides to settle for Dick Cavett's.
Tropes associated with Zalgar:

Pinky, Elmyra and the Brain Characters

     Elmyra Duff 
Voiced by: Cree Summer
The annoying redhead from Tiny Toon Adventures. She turned up to chase the Warners in one of their segments, but is listed here because of her being shoehorned into Pinky and the Brain. See Tiny Toon Adventures for her tropes.

     Pussy Wussy 
Voiced by: Frank Welker
Elmyra Duff's pet cat.
Tropes associated with Mr. Pussy Wussy:

  • All Animals Are Dogs: He started out as a cat hungry for Pinky and the Brain (because, you know, they're mice). But then came "The Cat Who Cried Woof," where Brain turned him into a dog. And he stayed that way for the rest of the series, averting Status Quo Is God.
  • Expy: Of Furrball from Tiny Toon Adventures.

     Mr. Shellbutt 
Elmyra Duff's pet turtle.
Tropes associated with Mr. Shellbutt:
  • Expy: Of Tyrone Turtle from Tiny Toon Adventures. Also appears to be this to Byron Basset, since he's the other most frequently seen pet from Furrball.

     Rudy Mookich 
Voiced by: Nancy Cartwright
http://static.tvtropes.org/pmwiki/pub/images/RudyWithHisPetSnake_2774.jpg
A fat slob who replaced Montana Max as Elmyra's love interest in Pinky, Elmyra and the Brain. Has the hots for Brain's occasional alter-ego, Patty Ann.
Tropes associated with Rudy:

     Vanity White

     Wally Faust

The seldom-seen antagonist of Pinky, Elmyra and the Brain, he is a man pursuing the mice to use in his own world domination schemes.
Tropes associated with Wally:
  • Advertised Extra: He only appears a handful of times even though he's seen in the show's intro.
  • Big Bad: He is the closest thing Pinky, Elmyra & the Brain has to a recurring antagonist, even though we barely see him.
  • Determinator: The opening shows how persistent he is in checking on the mice he needs for world domination. So persistent that they "had to flee constantly, needing a place to hide".
  • Early-Bird Cameo: Sort of. Christopher Walken has made at least a couple appearances on Pinky and the Brain before this guy appeared.
  • Evil-Detecting Dog: Okay, evil-detecting cat, but still, a nearby alley cat sees Wally, and yowls in fear.
  • Greater-Scope Villain: The Circle as a whole could qualify under this, as it's suggested that he's just an agent, not their leader, but it's hard to tell.
  • Knight of Cerebus: Reflected in the opening of the show. Elmyra's house and her surroundings are bright and colorful, but Wally Faust is almost always seen as a shadowy silhouette, and his surroundings are much darker. The few episodes featuring him also tend to be notably more serious in tone.
  • Manipulative Bastard: He tried to manipulate Brain into a trap. Tried to, but he came kinda close.
  • No Celebrities Were Harmed: He is clearly modeled after and talks like Christopher Walken.
  • Ominous Latin Chanting: His presence is accompanied by this. Well, sort of. They're really saying things like "gingivitis," "lactose," and "gluteus maximus".
  • Series Continuity Error: In the show's opening, Pinky and the Brain clearly know who Wally Faust is and what he wants with them, yet in his debut episode, they act like they don't know who he is or what he wants with them until it came to Brain's "cheese ray". Their ignorance made it easy for Wally to almost lure them into his trap. Well, that's what happens when you take candy from strangers.
  • Verbal Tic: He likes to say "crisply" in his sentences.
