"I'm not gonna scare you. I'm off-duty."

One of the series' two protagonists. He is a large, bear-like monster with shaggy blue fur, purple polka dots, a colossal tail, and curvy beige horns.

  • The Ace: The top scarer in Monsters Inc.
  • Accessory-Wearing Cartoon Animal: Wears a plaid tie at the end of the first movie as the new CEO of Monsters, Inc..
  • Anti-Hero: In the prequel, he starts off as being condescending and arrogant. He gets better, but that doesn't stop him from cheating at the final round of the Scare Games out of a lack in faith in Mike's scaring skills.
  • Arbitrary Skepticism: In the Laugh Factory comics, he and Mike find the idea of toys coming to life ridiculous, though an interesting idea.
  • Bears Are Bad News: In the prequel, he is this to the police in the summer camp, who mistake him for a bear.
  • Beary Friendly: He partially looks like a bear, and is a humble fellow despite his monstrous looks.
  • Beware the Nice Ones: He is kindhearted, but he can be ferocious when he has to.
  • Big Damn Heroes: He rescues Boo from the Scream Extractor.
  • Big Guy, Little Guy: Sulley plays the large-but-gentle Big Guy to Mike's smaller, snarkier Little Guy.
  • Blue Is Heroic: One of the definitely heroic protagonists, and is covered in blue fur.
  • Brains and Brawn: The Brawn to Mike's Brains. Sully has the physique and natural talent to bring out the scares.
  • Bruiser with a Soft Center: Sulley has super strength and a mighty roar, but is really a sweet guy under it all.
  • Brilliant, but Lazy: In college, where he had the physique to be a naturally talented Scarer, but he lacks the motivation to study the field and would prefer to rely on his roaring for all kinds of scaring.
    "You don't have to study scaring! You just do it!"
  • Celibate Hero: Neither in the prequel or the original movie does he show serious pursuance of women (aside a small gag where he flirts with a couple of school girls in Monsters University). His companion Mike is the one romantically active.
  • Character Development: is initially arrogant in Monsters University because of his talent. He gets better, though.
  • Delinquent Hair: While not really a delinquent, Sulley sports a fauxhawk in his college days, which compliments his initial Jerk Jock personality.
  • Deuteragonist: Of Monsters University, where Mike is the protagonist. He doesn't even appear for the first 15 minutes.
  • Dumb Jock: Played with. In college Sulley was naturally talented, and consequently unmotivated to work hard in school. He comes around, though.
  • Et Tu, Brute?: His very reaction to his mentor and best friend banishing him and Mike to the Himalayas is of utter shock.
  • The Exile: After Waternoose's duplicity is revealed, he's exiled to the Himalayas.
  • Experienced Protagonist: By the time of Monsters, Inc., Sulley's already been in the scaring game for years and is considered one of the company's top scarers.
  • Foil: To Randall. He and Sulley are the two best scarers of the company, got their scaring education at Monsters University and had the same Scaring 101 class. However, Sulley is a mammalian monster while Randall is reptilian. His color scheme is primarily blue with a bit of purple while it is the opposite for Randall. Sulley's strengths involve charging in at brute force while Randall has to sneak around, using his invisibility to be physically effective. Sulley is sociable in both his college and adult years, and was more of a jock in college. Randall was always isolated from most monsters and was a nerd in his academic days. Sulley was an arrogant jerk in college who got kicked out of Roar Omega Roar for his poor grades. He had an intense rivalry with Mike, but eventually softened up to him and weaker monsters. However, he ended up expelled from MU and humbled himself after becoming a scarer by climbing up the corporate ladder at Monsters, Inc. Randall was sweet and self-deprecating in college, and got kicked out of Roar Omega Roar for his poor performance in the final round of the Scare Games. While Randall still continued to study and became a scarer after graduation from MU, he grew to resent other monsters, especially Sulley and Mike, the latter being his closest friend prior to the Scare Games, and his mindset started to become fueled by his vices.
  • Four-Fingered Hands: Like several other monsters, probably to make the animation process easier.
  • Four-Temperament Ensemble: A mixture of Phlegmatic and Melancholic. He's humble despite being the best at his job, but he keeps up his rivalry with Randall and at first does not handle Boo getting into their world at all.
  • Gentle Giant: He is very nice, despite being over seven feet tall.
  • Heel Realization:
    • One of the most powerful scenes in the movie is Sulley, when inadvertently scaring Boo, realizing just what he's been doing to children all this time.
    • Likewise in the prequel as he bonds more with Mike and Oozma Kappa and realizes what a jerk he's been.
  • The Hero: Of Monsters, Inc., though he becomes The Lancer in Monsters University.
  • Heroic BSoD:
    • He goes through a brief one when he inadvertently scares Boo and gets exiled by Waternoose.
    • By the end of Monsters, Inc., he has another one when Waternoose blames him for destroying the company. He recovers once he finds out a way to keep up the factory by using children laughter.
  • Heterosexual Life-Partners: With his best friend Mike, who he lives and works alongside.
  • Honest Corporate Executive: Sulley becomes one at the end of the film.
  • Horrifying Hero: He's a monster, what would you expect?
  • Humble Hero: Whenever he's praised for his skill as a scarer, Sully typically waves the compliment off and simply says he's doing just his job.
  • I Did What I Had to Do: Regarding tampering with Mike's Scare Simulator so he'll be guaranteed to get a record scare, although he comes to regret this.
  • I Was Quite the Looker: Not to us (Unless you're into that sorta thing) but if you pay close attention, you’ll notice that back in his college days he was a lot leaner, had brighter, shiner fur, and more of it on top of his head.
  • Inadequate Inheritor: He mentions to Mike that despite his arrogance, he is quite insecure due to the pressure the Sullivan family puts on him, as Sulley's father was a famous scarer (hence doing anything he can to get back into the Scaring Program).
  • Inferiority Superiority Complex: Supposed to be this in contrast to Mike in University. While Mike isn't scary, he's extremely skilled and ridiculously confident, whereas Sulley has the traditional scaring build as an ideal monster, but he's insecure, terrified and feeling pressed by fellow peers because of his famous surname. He gets better in the sequel.
    Sulley: I act scary Mike, but most of the time... I'm terrified.
  • Ink-Suit Actor: He's really just a hairy John Goodman, well, a hairier John Goodman.
  • Jerkass: In Monsters University, he's largely inattentive, apathetic, and outright rude to many of his peers. It just may be an act though.
  • Jerk Jock: Hand in hand with his jerkass personality, he was even a member of the Roar Omega Roar fraternity until he got thrown out of the scare program.
  • Jerk with a Heart of Gold: Over the course of the film, he outgrows this and becomes a much better person.
  • The McCoy: To Mike's Spock and Randall's Kirk. His main goal becomes to get Boo back home safely, despite Randall's meddling and Mike's reluctance to get involved.
  • Meaningful Name: In French, "j'aime" can mean "like", "love," or "cherish"; the word "sully" means "to soil or tarnish". A lot of the narrative concerning Mike and Sulley variously involves their relationship being troubled or causing trouble.
  • Mighty Roar: His loud, lion-like roar is one of the reasons Sulley's so good at scaring children. This comes to bite him in the rear when he accidentally scares Boo with it.
  • Mistaken for Gay: It's implied that Celia thought this when Sulley turned up at her date with Mike.
  • My God, What Have I Done?: In Monsters Inc, one of these prompts his Heel Realization as indicated in the above entry.
  • Nice Guy: He becomes this by the end of Monsters University, and he's consistently polite in Monsters Inc.
  • Only Known by Their Nickname: He's rarely referred to by his first name outside of Mr. Waternoose and everyone else calls him "Sully".
  • Papa Wolf: He steadily becomes this to Boo, big time.
  • Parental Substitute: A lot of Sully's interactions with Boo start to resemble that of a father and daughter relationship. Even lampshaded by a babysitter.
  • Power Walk: Leads the one in the first film.
  • Purple Is Powerful: He's extremely strong, he's the best scarer at Monsters Inc, and he has purple patches of fur on his otherwise blue body.
  • Pursue the Dream Job: Foregone Conclusion in Monsters University, since we know that Sully becomes MI's top scarer, but after getting kicked out of school he and Mikey are shown starting in the mail room, being janitors and cafeteria cooks, until finally a chance for a shot at the coveted scarer position becomes available.
  • Red Oni, Blue Oni: Red oni to Mike's blue, which is more prominent in the prequel.
  • The Slacker: In college, a contrast to Mike's nerdy behavior.
  • Spell My Name with an "S": Unlike several other Sullivans with a nickname derived from their surname, this monster's name isn't "Sully" but "Sulley".
  • Straight Man and Wise Guy: Sulley plays the sane, reasonable straight man to Mike's goofy comic relief.
  • Super Strength: Prominently displayed during his fit of Unstoppable Rage when he goes saving Boo. The secret door and the scream extractor are no match for him.
  • Technician vs. Performer: The Performer to Mike's Technician.
  • Took a Level in Kindness: In Monsters University, he starts out as snob, but he develops into the kindhearted beast he is in Monsters, Inc.
  • Unskilled, but Strong: In college, this is how Sulley, at first, impresses his teachers; he barely studies, but his natural abilities still make him a great scarer. However, Reality Ensues when he's properly evaluated, and he finds a single great roar can't account for every kid.
  • Vitriolic Best Buds: His rivalry with Mike eventually becomes this kind of relationship. By the time the events of Monsters, Inc. happen, they regularly interact with each other through friendly banter.
  • "Well Done, Son!" Guy: His relationship with his father isn't even delved into but the expectations over his great family name is what drove his insecurities.
  • Wham Line: To Mike regarding his scaring skills after he found out Sulley cheated in University:
    Sulley: What, am I gonna let a whole team lose because you don't have it?!"
  • Wouldn't Hurt a Child: Even though he is the number one scarer at the company, he would never intentionally wish any real harm to a child, in contrast to Waternoose and Randall Boggs, even having a Heroic BSoD moment when he sees the frightened look on Boo's face after reluctantly operating the Scare Simulator at Waternoose's insistence.
  • You Gotta Have Blue Hair: Fur, but it counts. With purple spots.
  • You Kill It, You Bought It: Non-fatal variation - he becomes the CEO of Monsters, Inc. after ousting Waternoose.

"You've been jealous of my good looks since the fourth grade, pal."

One of the series' two protagonists. He is a ball-shaped monster with light green skin, two small horns, and one gigantic eyeball.

  • Affectionate Nickname: Celia addresses him as "Googly Bear".
  • Ascended Extra: Deuteragonist and Plucky Comic Relief in the original movie, and the smart protagonist in the prequel.
  • Arbitrary Skepticism: In the Laugh Factory comics, he and Sulley find the idea of toys coming to life ridiculous, though an interesting idea.
  • Awesomeness by Analysis: His main talent as shown in Monsters University, which is what makes him an excellent scaring coach.
  • Badass Bookworm: Pulled off, in Sulley's words, "the biggest scare the school has ever seen" simply by reading about the theory behind it and then applying the knowledge.
  • Berserk Button: He gets upset whenever Sulley doesn't listen to his plans. It gets to the point that Mike assaults him after they are banished to the Himalayas.
  • Big Guy, Little Guy: Mike plays the smaller, snarkier Little Guy to Sulley's large-but-gentle Big Guy.
  • Brains and Brawn: The Brains to Sully's Brawn. Mike has an encyclopedic knowledge of all things scaring and uses that knowledge to coach Sully.
  • Breakout Character: Went from Plucky Comic Relief Sidekick to being the protagonist of the prequel.
  • Break the Cutie: He was very optimistic and dorky in the prequel until he got kicked out from the scare program, and had to train a loser team into masters to be able to be in the program he wanted. It didn't work for him since he lacked the spark everyone else in the team had, thus he was never educated as a real scarer.
  • Butt-Monkey: Mike takes a lot of comedic abuse throughout the movie, which Boo finds hysterical. He gets bitten, suffers a Groin Attack, falls into a toilet, gets kidnapped by Randall and banished to the Himalayas, the list goes on.
  • Cassandra Truth: When Mike goes back to the human world and flees from Randall alongside Sulley, Celia tosses herself at him out of anger and threatens to break up with him if he doesn't tell her the truth about what's going on. Mike explains the whole situation regarding the child and Randall and Waternoose's plot. Celia angrily expresses her disbelief, only for Boo to pop out and say Mike's name, causing Celia to let go of Mike in shock. She instantly believes him once Boo shows up.
  • Cephalothorax: Mike's entire body is basically a round ball with arms and legs attached, with his face taking up the entire "ball."
  • The Charmer: Shows this around Celia.
  • Copiously Credited Creator: The DVD extras show a playbook for "Put That Thing Back Where It Came From Or So Help Me!", showing that Mike wrote, directed, created the costumes, etc. invoked
  • Cyclops: He consists of a giant eye, a mouth underneath, and limbs.
  • Deadpan Snarker: Has his moments, especially in Monsters, Inc..
  • Determinator: MU shows this side of him. Nothing keeps him down.
  • Deuteragonist: Of Monsters, Inc., though he gets his day in Monsters University.
  • Doomed by Canon: His character in the prequel. He really wants to become a scarer but we already know he's going to fail, since in the first film he is just Sulley's assistant.
  • Drill Sergeant Nasty: Sulley and his morning work-out routine.
  • Dude, Where's My Respect?: Suffers from this in the prequel. Everyone, even Oozma Kappa, consistently praises Sulley for looking like a scarer and will be the winning load of the team, when it's actually Mike carrying them all the way to the top. Sulley admits this at the end and praises Mike for it, though.
  • Earn Your Happy Ending: Sulley and Mike get kicked off the scare program at Monsters University, take 6 misfits and turn them scarer material just for the chance to get back on. They end up expelled. Undeterred they decide to work their way up together at the ranks at Monsters Inc, from the mail-room up, until they become scarers. They then become the greatest scaring team on record. Only to uncover corruption at their workplace and inadvertently close down the business they worked so hard for. Fortunately they discovered a new means of power along the way. Fittingly, having lost his dream of being a scarer, it is Mike who now gets to take the lead and become one of the greats in his business.
  • Establishing Character Moment: It isn't that clear at first, but in M.U., when a young Mike is mistakenly left behind in the bus, he seems too naive to take offense and instead rejoices over finding a nickel on the bus.
  • The Exile: He's exiled to the Himalayas along with Sulley.
  • Extraverted Nerd: As a college student he's incredibly nerdy about scare methods.
  • Foil: To Randall. In college, Mike and Randall were both nerdy and physically weak monsters who majored in Scaring. Randall had no faith in his scaring abilities, while Mike believed in himself to the point of overconfidence. Although Mike did get the best score in the Scare Games, he was expelled from MU and climbed up the ladders to become a scare assistant. Randall got the worst score in the Scare Games, but completed his education and became a Scarer.
  • Four-Fingered Hands: Like several other monsters, probably to make the animation process easier.
  • Four-Temperament Ensemble: Sanguine with a dash of Choleric. He is genuinely dedicated and takes great pride in his job and loves Celia deeply and dearly, but when it comes to the trouble Sully and Boo get them all in, he is very unhappy and lets his lack of amusement known.
  • Growing Up Sucks: Sacrificed his life-long dream as an on-field Scarer. Even though he works his way into being treated like an equal to on-field Scarers, it doesn't make his past pains any less significant.
  • Hard Work Hardly Works:
    • Mike works very hard to prove himself capable of scaring in Monsters University, but his appearance and size do not help him in the field. And not only does his final effort of proving himself fail, it gets him expelled from MU.
    • Also averted, as he and Sulley climb the ranks at Monsters Inc. until they become a full-fledged scare team. Mike's hard work ultimately brings him to the position as a scare coach rather than a scarer. Not only that but one of the top scarers in the company. Heck even before then, as Sulley and he were working their way up the company. They would in the top in a lot of simple fields such as Mail Clerk, Janitorial Work and Cafeteria Workers. Before ultimately landing a job as scarers, no doubt thanks to his coaching.
  • The Heart: According to Sulley, he's the heart and soul of the team (Oozma Kappa).
  • Heroic BSoD: He goes through this when Sulley tells him that he doesn't have what it takes to be a real scarer.
  • Heterosexual Life-Partners: With Sulley, who he coaches. The two work together and even share an apartment.
  • Hidden Depths: What we learn about him in the original film never implies that he is the book smart hard-working guy we see in the prequel.
  • High Hopes, Zero Talent: In the prequel, Mike is constantly told he can never become a scarer because he simply isn't scary. It eventually turns out they're right.
  • Horrifying Hero: Subverted, Mike is extremely knowledgeable, but isn't very scary the same way Sulley can be. Even when he attempted to do so on his own in the second film, none of the kids were scared of him, and in fact found him kind of adorable.
  • Hypercompetent Sidekick: If you take the prequel into account, and being the Sidekick in the original, he is this.
  • I Just Want to Be Special: In Monsters University. Unfortunately, his dream of becoming a scarer himself doesn't work out, but he does end up becoming a scare coach and lifelong friend to Sulley along the way. Though at the end of Monsters Inc he eventually finds himself uniquely suited to making kids laugh and helping end the energy crisis. It just took a long time for him to get there.
  • Ink-Suit Actor: Even as an adorably inhuman monster, Mike could not be more Billy Crystal.
  • It's All About Me:
    • Suffers from this briefly in the prequel. When he enters the Scare Games, his only condition during his bet to Hardscrabble is that he gets back into the scare program if he wins, is more concerned about proving himself better than Sulley than actually getting his team through the first event, and is dismissive of teammates, simply telling them to forget everything about themselves and follow his lead. Initially, Hardscrabble indirectly calls him out on it by expanding his offer to include the entire team, but it doesn't really take until his team manages to complete the second event without him.
    • Suffers from it again in Monsters, Inc., even more extreme than before. When they’re both banished to the Himalayas, Mike blames Sulley for getting him trapped there, and is only concerned about how his life and dreams has been ruined.
  • Jerkass Has a Point: When he and Sulley are banished to the Himalayas, he clearly doesn't care about how horrible Sulley feels over accidentally scaring Boo, is bitter over how Sulley essentially ruined ''his'' life and aspirations by ignoring his advice ever since Boo came into the picture, and more distraught over how close he and Sulley were to breaking the all-time scare record before getting banished than how many innocent human kids Waternoose and Randall will put at risk with the scream extractor. However, Mike's resentment at Sulley is not exactly without merit considering how he was more or less dragged into Sulley's problem against his will and had his relationship with Celia ruined without getting a chance to share his side of the story with her or make things right with her.
    • His fury at Sulley becomes much more understandable when the prequel reveals that the path they had to go on to get where they were at point in their lives involved getting booted from the scare program of Monsters University, joining the least popular fraternity on campus and helping its members realize their true potential as scarers for a chance at getting back into the program only to be expelled from the school after a terrifying visit to the human world, after which they got employed in the mailroom of Monsters Inc. where they worked position after position until they got qualified to work on the scare floor. And between the two of them, Mike arguably had it the worst given how his dream of becoming a scarer was constantly ridiculed by both his peers and professors by being told he wasn't scary and then realizing they were all correct after trying to scare a real child resulted in him and Sulley nearly getting trapped in the Human world.
    • While he isn't that much of a Jerkass, he did make a good point about Sulley becoming attached to Boo when he gives her a nickname.
  • Jerk with a Heart of Gold: Thoroughly self-centered with a large ego to match, but a loyal friend to Sulley and Oozma Kappa anyhow. In the original, he also learns to warm up to Boo after he had been trying to get rid of her for the whole movie.
  • The Lancer: How Mike views Sulley, even though he himself is the Lancer in Monsters, Inc. In Monsters University, it is more clear that Mike is The Smart Guy behind the duo.
  • Large Ham: His personality can be quite dramatic, especially when he makes children laugh at the end of Monsters, Inc.
  • Literal-Minded: In the scene where Randall and Fungus have him captive, Randall tells him to "say hello to the Scream Extractor", and he does just that.
  • Mistaken for Gay: Again, implied by Celia's reactions to Mike and Sulley's interactions on their date.
  • Motor Mouth: He talks a lot, and really fast. Specially if he's angry.
  • Nice Hat: His blue MU baseball cap given to him by Frank McCay. There's also his blue Monsters, Inc. hardhat, which is arguably more iconic.
  • Oculothorax: A giant eyeball, with a small mouth and spindly arms and legs.
  • Official Couple: He gets together with Celia.
  • Oh, Crap!: In Monsters University, after realizing that not only is the girl not scared of him, but he's stuck in a summer camp full of kids.
  • Plucky Comic Relief: His role in Monsters, Inc..
  • The Pollyanna: He was this to everyone's disapproval of him, until he got kicked out from the scaring program and could never be a scarer.
  • Rage Breaking Point: Mike spends the whole movie irritated that Sulley continuously ignores his suggestions after getting him roped into the situation with Boo. When Sulley still ignores him after getting them both banished, Mike explodes in anger and attacks Sulley.
  • Red Oni, Blue Oni: Blue oni to Sulley's red, which is more prominent in the prequel.
  • Shorter Means Smarter: In college, Mike was one of the university's shortest monsters, and also among the smartest, most studious ones.
  • Sidekick: Interestingly enough, Mike sees Sulley as his sidekick. In Monsters University, this is explained by showing Sulley as being very dependent on Mike's intellect and knowledge.
  • Sickeningly Sweethearts: He and Celia frequently refer to each other by cheesy pet names. "Schmoopsie-Poo" for Celia and "Googly Bear" for Mike.
  • Skewed Priorities: He and Sulley are trapped in the Himalayas, Waternoose and Randall are about to use their machine on Boo (plus a thousand other children, not to mention whatever number of children they might have used it on beforehand), and all Mike can think about is how Sully got him trapped in “this frozen wasteland”, and that they were about to beat the Scare Record.
  • The Smart Guy: Coaches Oozma Kappa into making them competent scarers, and later serves as Sulley's coach at Monsters Inc., who is now the best scarer in town.
  • The Spock: To Sulley's McCoy and Randall's Kirk.
  • Stepford Smiler: On his school field trip. He is acting really chipper and occasionally snarks about, but both when he ends up without a field trip buddy and when a classmate tells him he does not belong on a scare floor, it is clear how disheartened he is. Shades of this character trait are also present when he is older, especially in his reactions to Randall's treatment of him.
  • Stock Audio Clip: Not as much as Boo, but his comical yelling has a tendency to be reused a few times.
  • Straight Man and Wise Guy: Sulley plays the sane, reasonable straight man to Mike's goofy comic relief.
  • The Strategist: Thanks to being book smart, Mike formulates plans and tactics that help out greatly during the second film, such as whipping Oozma Kappa into a fairly competent scaring team, and later when he and Sully get trapped in the human world, and he devises a plan to scare the rangers so that they can power the door from the human side. It also has the bonus of surprising Dean Hardscrabble, which had never been done before.
  • Technician vs. Performer: The Technician to Sulley's Performer.
  • Tiny Guy, Huge Girl: Tiny Guy to Celia's Huge Girl.
  • Took a Level in Kindness: An arc in MU. Joins Oozma Kappa for his own motives in order to revive his chances in the Scaring Program. After barely passing the first competition, he holds Oozma Kappa to a rather conforming (ineffective) method in the library challenge. But when he sees that the Oozmas have competence of their own, he becomes more appreciative of them and more accommodating to their special abilities.
  • Tragic Dream: Worked from a very young age to become a scarer. Nobody truly believed in him and in the end it didn't work out, though he did become Sulley's best friend and discovers a true greatness in serving as scare coach along the way. Subverted when he turns out to have quite the talent for making children laugh and so he does become a great in his field of expertise after all. Albeit in a very different way than he'd thought.
  • Vitriolic Best Buds: His rivalry with Sulley eventually becomes this kind of relationship. By the time the events of Monsters, Inc. happen, they regularly interact with each other through friendly banter.
  • Weak, but Skilled: In college. In fact, it is the plot point in University; he is incredibly ambitious, which leads him to being extremely good in his grades (getting straight A's), but since he doesn't have that certain "spark" which is required for a scarer he never lives up to his dream and becomes Sulley's assistant in the sequel.
  • Wrong Line of Work: Mike enrolls in the Monsters University Scarer Program so that he can become the best scarer ever, and accumulates an enclopedic knowledge of scare tactics. However, after being failed out of the Scraer Program by Dean Hardscrabble, and after discovering that Sulley sabotaged his turn during the Scare Games so that Oozma Kappa could win, Mike faces the Awful Truth that he's not a frightening monster, and gives up on his dream of ever becoming a scarer. After working his way to the scare floor at Monsters Incoprorated, he uses his vast knowledge of scaring to help Sulley become the best scarer in the company, and after discovering that laughter is more powerful than scream Mike evetually finds his life's calling, making children laugh as a comedian.

Voiced by: Mary Gibbs

A human toddler who doesn't fear any monster except for Randall. She accidentally enters the monster world when Sulley inspects her door at the Scare Floor, setting Mike and Randall to find a way to send her back to her house.

  • The Unintelligible: Speaks mostly in childish gibberish, save for words like "Kitty".
  • Why Did It Have to Be Snakes?: Boo is remarkably sanguine about finding herself in a world full of monsters, but she's absolutely terrified of Randall, her scarer. Her file indicates that she actually is afraid of snakes.

    Randall Boggs 
Voiced by: Steve Buscemi
Click here  to see Randall as he appears in Monsters University
"I'm in the zone today, Sullivan."

The first film's main antagonist, and a supporting protagonist-turned antagonist in the prequel. He is a reptilian monster with both chameleon and snake-like features. He has purple scales, a blue tail, four arms, four legs, and three pink fronds on the top of his head. He also has the unique ability of becoming completely invisible.

  • Ain't Too Proud to Beg: When Sulley and Mike are about to exile him, he pleads them not to. It doesn't work.
  • Always Second Best: No matter how much effort he puts into it, he'll never become a better scarer than Sulley, a fact Waternoose acknowledges to Randall even after the former exiles Sulley for the sake of their Evil Plan.
  • Bad Boss: Often seen bossing around Fungus and gets into heated disagreements with Mr. Waternoose.
  • Big Bad: He is the mastermind behind the Scream Extractor. However, it is revealed that he is in a Big Bad Duumvirate with Mr. Waternoose.
  • Big Bad Wannabe: Randall may be the Big Bad, but he only gets somewhere because his boss was so desperate to end the energy crisis that he decided to work with him.
  • Bitch in Sheep's Clothing: Despite being Mike's roommate in college, he was something of a popularity seeker who joins up with ROR and participated in the prank to discredit his old friend's team, although peer pressure might have been a factor.
  • Blind Without 'Em: Well, not necessarily blind, but after he abandons his glasses due to Mike suggesting he do so in order to make the most out of his camouflage ability, he keeps his eyes constantly squinted in order to see. By the time Monsters, Inc. comes around, he's still squinting.
  • Card-Carrying Villain: He apparently knew what he was doing was evil as he told Fungus not to fraternize with victims of his plan. Those were Fungus' words, not his own, so Fungus might have just been projecting his unease about the whole shady deal unto his view of Randall.
  • Cheshire Cat Grin: It fits considering he is like a reptilian version of the Cheshire Cat.
  • Continuity Nod: After shedding his glasses away in the prequel, he begins squinting due to his poor eyesight, much like how he does in Monsters Inc.
  • Demoted to Extra: In the prequel. While he frequently shows up in the beginning as Mike's studying partner, he doesn't do anything significant to the plot except joining Roar Omega Roar, forcing Mike to team up with Sulley.
  • Disc-One Final Boss: Despite being one-half of the Big Bad Duumvirate, by the time he's defeated by Sulley and Mike, there is still another member of the duumvirate for the duo to take down: Waternoose.
  • Establishing Character Moment: In the prequel, he is introduced by happily shaking Mike's hand while saying that they'll be best friends, and then disappearing out of nowhere and apologising in embarrassment, showing his hopeful, but awkward personality. In Monsters, Inc., his first appearance consists of him confusing Mike by shutting his locker's door while being invisible, and then appearing out of nowhere to jump scare him. He then chuckles at Mike's fright and mockingly remarks that his tactic works on "little kids and little monsters".
  • Evil Counterpart: To Sulley. In college Randall was nice and Mike's best friend, while Sulley was a jerk and Mike's rival. This changes over the course of the movie, and by the end their roles were completely reversed. By Monsters Inc we see Sulley as the Gentle Giant best friend of Mike and Randall as the evil arch-rival who hates both of them.
  • Evil Former Friend: To Mike. He was his best friend and roommate in the prequel before his Face–Heel Turn.
  • Evil Genius: Invents the Scream Extractor.
  • Expy: Of the chameleon carnotaurs from "Jurassic Park: The Lost World" novel. Ironically, the Indoraptor in Jurassic World: Fallen Kingdom (which also features Carnotaurus but it can't/doesn't camouflage) is one of him to substantial degree.
  • Face–Heel Turn: He used to be a friend of Mike's in Monsters University, but decided to partner with Roar Omega Roar instead and swore revenge on Sullivan for accidentally ruining his scare simulation.
  • Foil: To Sulley and Mike.
    • In college, Mike and Randall were both nerdy and physically weak monsters who majored in Scaring. Randall had no faith in his scaring abilities, while Mike believed in himself to the point of overconfidence. Although Mike did get the best score in the Scare Games, he was expelled from MU and climbed up the ladders to become a scare assistant. Randall got the worst score in the Scare Games, but completed his education and became a scarer.
    • Sulley and Randall are the two best scarers of the company, got their scaring education at Monsters University and had the same Scaring 101 class. However, Sulley is a mammalian monster while Randall is reptilian. His color scheme is primarily blue with a bit of purple while it’s the opposite for Randall. Sulley's strengths involve charging in at brute force while Randall has to sneak around using his invisibility to be physically effective. Sulley is sociable in both his college and adult years, and was more of a jock in college. Randall was always isolated from most monsters and was a nerd in his academic days. Sulley was an arrogant jerk in college who got kicked out of Roar Omega Roar for his poor grades. He had an intense rivalry with Mike, but eventually softened up to him and weaker monsters. However, he ended up expelled from MU, and humbled up after becoming a Scarer by climbing up the ladders at Monsters, Inc. Randall was sweet and self-deprecating in college, and got kicked out of Roar Omega Roar for his poor performance in the final round of the Scare Games. While Randall still continued to study and became a scarer after graduation from MU, he grew to resent other monsters, especially Sulley and Mike, the latter being his closest friend prior to the Scare Games, and his mindset started to become fuelled by his vices.
  • Four-Temperament Ensemble: Mainly Choleric, with some Melancholic elements here and there. He is very irritable and selfish and shows quite a lot of callousness towards whatever happens to Fungus, and also seems to have carried over some of his intelligent traits from Monsters University, while also being rather resentful about Sulley being a better scarer than him.
  • From Nobody to Nightmare: As Monsters University shows, he turns into this.
  • Geek Physiques: In his college years, Randall was still scrawny, but he also had huge glasses and some of his scales are colored in a way that implies that there are his equivalent to acne.
  • Glass Cannon: He's pretty strong, and his invisibility is a great help as shown in his fight with Sulley. Sulley couldn't even touch him until Mike revealed his location by hitting him with a snowball. But once that happened, all it took was one backhand to take him down.
  • Green-Eyed Monster: Not only is he literally a monster with green eyes, but he is also extremely envious of Sulley's success. Randall might easily outrank all of the other Scarers in his floor, and perhaps the entire company, but he is never satisfied due to Sulley barely beating him every time. It's implied that his envy is what fuels his desire to go with his Scream Extractor plan.
  • Handicapped Badass: Randall apparently has eyesight so bad he needs to squint constantly to see properly, but that doesn't stop him from being the second-best scarer in the industry, nor does it stop him from almost killing Sulley in a fight.
  • Hate Sink: In the first film. Whereas Waternoose is an Affably Evil Well-Intentioned Extremist, Randall is a selfish, arrogant scumbag who has no redeeming qualities whatsoever. Even in the prequel wherein he seems to be an awkward, friendly geek, he quickly turns tail on Mike with no remorse the minute he finds more popular friends to bump his status.
  • Heel–Face Turn: In the Scream Arena spin-off game, he's shown to have returned to Monstropolis and fully embraced the idea of making kids laugh by playing dodgeball.
  • Hollywood Chameleon: He can practically turn invisible. Justified as he's clearly not meant to be an actual chameleon.
  • I Just Want to Be Special: In college he was a shy student who really wanted to befriend the cool guys.
  • I Just Want to Have Friends: In college. Preferably if they're cool, which leads him to dumping Mike for ROR.
  • Incoming Ham: De-cloaking while yelling "WAZOWSKI!" to startle Mike. Quite the intro.
  • Ink-Suit Actor: Hard to look at him while talking and not remember Buscemi.
  • Invisibility: Given he can change himself to the colors of the environment.
  • Invisible Jerkass: His Establishing Character Moment has him using his invisibility to scare Mike in the locker rooms. He only gets worse from there.
  • It's All About Me: In Monsters University, Randall abandons Mike, just to fit in with the cool monsters because he doesn't have any friends, not even caring that Mike was a good friend to him at the very start.
  • I Was Beaten by a Girl: He is beaten up by Boo when he tries to kill Sulley.
  • Jerkass: Randall is an impatient and bitter jerk who doesn't show any respect for any other character, not even his boss Waternoose, who decides to work with him out of desperation. He frequently intimidates and threatens his assistant, Fungus, is progressively crueller and snider to Sulley as the story progresses out of mere envy, and displays sadistic enjoyment out of tormenting Mike, seeing Sulley and Mike getting banished and possibly torturing Boo to death.
  • Large Ham: Can be quite dramatic at times. The jittering and mugging helps!
  • The Kirk: To Sulley's McCoy and Mike's Spock in Monsters University. He firmly believes that Boo (and all human children) are disgusting creatures at worst and expendable sources of energy at best, but his main drive is to get back at Sully for their rivalry.
  • Laser-Guided Karma: In the prequel, he joins with his and other fraternities to pull a nasty prank against OK in their party to make them into "adorable monsters". Later in the final round of Scare games, he accidentally camouflages the heart motif from the scare simulator room over his whole body, which turned him into an "adorable monster" himself. Even his fraternity captain has no qualms in mocking him for this.
  • Last-Name Basis: Refers to Sulley and Mike by their last names out of antagonism. Especially since he referred to Mike by his first name in Monsters University, but never referred to Sulley by his first name or nickname.
  • Lean and Mean: Just compare him to Sulley or most of the other scarers who all seem big and muscular.
  • Lizard Folk: He resembles a lizard.
  • Loud Gulp: He gulps loudly the moment Sulley tells him he's out of a job.
  • Lovable Lizard: Zig-zagged. In the original movie, he, a lizardlike monster, was portrayed as pure evil. But Monsters University shows his Start of Darkness. As a teen, "Randy" was a shy, nerdy, and innocent guy who just wanted to make friends. This led him to join the Jerk Jock fraternity, only for them to cast him out when he loses the big game to Mike and Sully, causing him to develop a grudge against Sully that guides his actions in the original movie. This is an interesting example because even though we know he's going to turn bad, his younger self in MU is still quite cute and relatable (until his last scene, in which he swears revenge on Sulley), making him a great (if retroactive) example of straying away from Reptiles Are Abhorrent.
  • Mean Character, Nice Actor: Implied by the Hilarious Outtakes, where he comments that he looks good in a suit after a coworker pulls a prank on him during filming.
  • Mix-and-Match Critter: Randall resembles both a chameleon and a snake.
  • Multi-Armed and Dangerous: Subverted. He has multiple arms, but they aren't the reason why he is so dangerous.
  • Narcissist: In one scene, we see him checking himself out in a mirror.
  • Nerd: In college, at least for the first half of the film. It can be assumed that he was this in high school as well.
  • Nerd Glasses: Sadly, he drops them within a minute of his first appearance under Mike's advisement.
  • No-Holds-Barred Beatdown: His fate at the end of the first film, he gets repeteadly whacked in the head with a shovel by a hillbilly.
  • Not-So-Well-Intentioned Extremist: He claims that he's going to revolutionize the scaring industry, but in fact he's only doing it for personal recognition.
  • Only Known by Their Nickname: In Monsters University he's called "Randy".
  • Outgrowing the Childish Name: Now he only goes by Randall, but the prequel reveals that he used to be called Randy when he was a harmless college student. He probably abandoned his nickname shortly after his Start of Darkness.
  • Out of Focus: The main antagonist of the first film, a relatively minor character in the prequel. However, aside from Sulley and Mike, he's the only major character who appears in both movies.
  • Power Walk: Participates in the one found in the first film.
  • Psycho for Hire: Under orders from his boss, he builds a horrific machine that sucks the screams out of human children. While Waternoose at least has the motive of keeping his company afloat and providing energy to Montropolis, Randall has no motive except to satisfy his own resentment over always being passed over in favor of Sulley, a college dropout who patiently worked his way to the top of the scaring game.
  • Reptiles Are Abhorrent: An interesting combination of traits. Chameleons typically don't fall victim to this trope, but he also resembles a snake.
  • The Rival: To Sulley since university. Overlaps with The Resenter, as his obsession with being better than Sullivan stems from being accidentally humiliated by him and being rejected by his ROR "friends" because of it (in his scare turn, the vibrations from Sulley's roar caused him to fall on a carpet and involuntarily blend in with its pink and heart pattern, ruining his scare score).
"That's the last time I lose to you, Sullivan!"
  • Shapeshifter Swan Song: Parodied. When he is being beaten up by Boo, he keeps changing colors cartoonishly, including, at one point, white with red stars.
  • Smug Snake: Figuratively and literally. He has a very high opinion of himself while simultaneously constantly being in Sulley's shadow and looks like an actual snake.
  • Social Climber: In Monsters University he was one of these, ditching Mike at the first opportunity to hang with the cool teens.
  • Sore Loser: In Monsters University, his loss to Sulley in the final event of the Scare Games gets him mocked in front of the school (he got the lowest score of his teammates), lost him all his friends, and served as a catalyst for his resentment of him in Monsters Inc.
  • Spared by the Adaptation: The Boom! Studios comic, the Scream Arena video game, and Kingdom Hearts III show that he survived the movie and got back to Monstropolis.
  • Start of Darkness: In Monsters University, he slowly turned from a nervous character who was close friends with Mike to a resentful foe who is Sulley and Mike's arch-nemesis.
  • The Starscream: It is hinted that he plans on backstabbing Waternoose after his Evil Plan succeeds.
  • Took a Level in Jerkass: It says a lot about someone when they're willing to casually murder their university dorm mate.
  • Torture Technician: Invents a horrific machine that will literally suck out children's voices.
  • Unknown Rival: Mike thinks of him as a competitor, while Sulley just thinks of him as a colleague. Randall, meanwhile, sees them as his adversaries.
  • Used to Be a Sweet Kid: He starts out being very polite, kind and supportive to Mike, and he seems to genuinely value their friendship, but he's led astray by his own desire for personal status. Eventually, he ends up joining the most high-up fraternity in a bid to become "cool", ending up as an adversary in the Games. When he's (accidentally) publicly humiliated by Sulley in the last Game, he develops his bitter resentment towards the former and Mike.
  • Vertebrate with Extra Limbs: Randall resembles both a snake and a lizard. He also happens to have four arms and four legs.
  • Vile Villain, Saccharine Show: Monsters Inc is a light-hearted franchise overall. Randall, however, stands out for being a ruthless, callous, attention-seeking sociopath who will do anything for his own benefit, even if it means hurting others.
  • Villainous Breakdown: After Waternoose tells Randall he will never amount to Sulley, he growls at him and forces him to accept his plan. Then when Sulley destroys and throws the Scream Extractor at Randall, Waternoose, and Fungus and saves Boo, Randall loses it and tries to kill Sulley (and was prepared to do so, even before Waternoose told him to).
  • Wall Crawl: Goes hand in hand with being a gecko-salamander-chameleon-thing.
  • We Used to Be Friends: Randall used to be Mike's roommate and friend in Monsters University before deciding to side against him.
  • Would Hurt a Child: His plan may not have been specifically aimed at killing children, but the results of the Scream Extractor are anything but harmless (probably lethal).

    Henry J. Waternoose III 
Voiced by: James Coburn
"There is nothing more toxic or deadly than a human child."

Waternoose is an elderly, grey-skinned, overweight monster with five eyes, seven digits on both hands, and six crab-like legs. He is the CEO of the eponymous company, a retired scarer, Sulley's mentor, and the boss of every character who works for the company. His plans to rejuvenate the company hide his sinister ambitions...

  • Acrofatic: Despite his portly frame, Waternoose can run surprisingly quick thanks to his multiple legs. When pursuing Sulley near the end of the movie, he has no problem keeping pace with him despite being much older.
  • Affably Evil: Waternoose is pleasant, reasonable, and has a good sense of humor. Too bad about the whole 'kidnaps children and extracts their screams' thing.
  • Benevolent Boss: Subverted. Was initially this to Sulley and Mike, then he is revealed to be part of Randall's plan on kidnapping human children for the sake of the company and resolving the energy crisis.
  • Big Bad Friend: Friendly enough that he genuinely did not want to banish Sulley and Mike to the point where he defends Sulley's reputation and snaps at Randall for insulting him. Unfortunately, this didn't stop him from going through with all of it.
  • Big Good: The benevolent CEO of Monsters Inc., Sulley trusts him enough to reveal Randall's treason. Except that Waternoose is working with Randall in a Big Bad Duumvirate.
  • Broken Pedestal: For Sulley when Waternoose turns on him and Mike, despite considering them best friends.
  • Corrupt Corporate Executive: Waternoose initially appears to be an Honest Corporate Executive who just wants to keep his company from failing, but the ongoing power shortages eventually force him to team up with Randall and kidnap children to drain their screams.
  • Engineered Public Confession: Sulley and Mike work together to entrap him, using the scare simulator as their medium.
  • Evil Sounds Deep: A Corrupt Corporate Executive with the voice of James Coburn. Though he is a Tragic Villain.
  • Extra Eyes: Waternoose has five of them.
  • Fat Bastard: He is quite wide in proportion to his height and he is a child-kidnapping Knight Templar.
  • First-Name Basis: The only one in the film to address Sulley by his first name James.
  • Four-Fingered Hands: He has seven fingers on his hands.
  • Funny Afro: Yes, he has this in the prequel! Well, only shown briefly in photograph, however, when he welcomed Sulley and Mike as the newest Scarer team in his company.
  • The Guards Must Be Crazy: When Mike informs him about the obviously fictional "Bring an Obscure Relative to Work Day", he simply says, "Must've missed the memo."
  • Half-Dressed Cartoon Animal: Only wears a tuxedo jacket with no pants.
  • Hoist by His Own Petard: A minor and somewhat humorous example early in the film: After the 23-19 on the Scare Floor, it's shown that even he gets scared when Sulley practices the Waternoose Jump and Growl on him. This one is Played for Laughs—even he knows that Sulley is a good enough scarer to get him with a scaring technique that he himself had perfected, and he considers it an admirable quality.
  • Honest Corporate Executive: Eventually Subverted. He seems to be reasonable in making sure that his company doesn't go in the red, but in truth, he's a Corrupt Corporate Executive.
  • I Did What I Had to Do: He feels that with the energy crisis growing worse and worse with each day due to human children becoming harder to scare, he needs to do what's best for his company and Monstropolis even if it means crossing legal and moral boundaries by abducting countless human children and putting them through Randall's scream extractor to forcefully obtain their screams.
  • Intergenerational Friendship: Between him and Sulley.
  • Knight Templar: Waternoose wants to save his family business and Monstropolis from collapse due to a power shortage. His "solution" drives him into would-be child slaughterer.
  • Large and in Charge: A large, overweight monster who's the boss of Monsters Inc.. When using his legs to prop himself up, he dwarves even Sulley.
  • Large Ham: He has an affable and boisterous personality, especially when he is excited.
  • Last-Name Basis: No one in the movie, not even his best Scarer, calls him Henry.
  • Mentor Archetype: He's implied to be such for Sulley, since he helped the latter become the company's top scarer. Waternoose is sincerely despondent when he has to get rid of him and in the climax while Sulley quite truly hopes he can convince him not to go through with the plan, sadly to no avail.
  • Mix-and-Match Critter: The most notable one in the movie, Waternoose has been described by several of the filmmakers as a cross between a crab and a spider.
  • The Mole: He and Randall are in charge of kidnapping children and made up the "poisonous human" superstition for the sake of keeping the company up and running to power Monstropolis.
  • Pragmatic Villainy: Implied. Judging by his words, his regret over banishing Sulley seems aimed more at the latter being his company's top scarer than an old friend.
  • Put on a Bus: To near literal levels. The CDA agents place him in their personal vehicle when they arrest him and drive away from the factory. Waternoose also doesn't appear in Monsters University aside from a cameo in a photo despite arguably being as important as Sulley, Mike, Boo, and Randall.
  • Reasonable Authority Figure: He's always reasonable to listen to his employees, especially Sulley. Or so it originally seems...
  • Red and Black and Evil All Over: Waternoose has grey skin and wears a black tuxedo jacket with a red undercoat. He turns out to be the Big Bad.
  • Retired Badass: Judging from dialogue, he was once a top scarer.
  • Signature Move: While he was a scarer, he was famous for his "Jump and growl", which Sulley uses on him early in the film.
  • Spider People: His design seems to be based on a mix of 'spider' and 'crab'.
  • Stout Strength: Waternoose is fat, but that insectoid biology seems to come with insectoid strength, as seen when he singlehandedly shoves both Sulley and Mike through their banishment door and during the climax; he breaks through a door that Sulley sealed off with a bent metal pipe, and then backhands the massive Sulley across a bed with little apparent effort. He's completely unafraid of chasing Sulley down alone, even though he is seen by this point the lengths Sulley will go to to protect Boo, and knows that Sulley must have beaten the invisible Randall by this point.
  • Tragic Villain: The company of his father and his father's father is in hard times, and there's an energy crisis throttling the city that is worsening with each day. With his company being the only thing that powers the city, he must act to save it and Monstropolis no matter how immoral his plan might happen to be. He even declares to Sulley as he's being arrested that because of Sulley's actions, Monsters Inc. will be destroyed, and the energy crisis will be even worse than it already was.
  • Treacherous Advisor: Waternoose is revealed to have been behind the conspiracy all along.
  • Utopia Justifies the Means: He just wants to save his city from an energy crisis. If this means kidnapping children and strapping them to a horrific machine to extract their screams, then so be it.
  • Villain Has a Point: At the end of the film, he tells Sulley that the energy crisis will only get worse since Sulley has exposed his crimes and almost made the factory shut down in the aftermath. Fortunately, Sulley's discovery of the laughter of children being significantly more powerful than their screams resolves this problem.
  • Villainous Breakdown: He loses it towards the end of the film to the point that he reveals his intentions to kidnap children to help his company's crisis.
  • Walking Spoiler: Outside of some subtle Foreshadowing, he doesn't show any clear signs of villainy during the first half of the movie.
  • Well-Intentioned Extremist: He just wanted to solve the energy crisis and save his family company... by kidnapping children and draining energy out of them through cruel ways instead of a short scare.
  • Would Hurt a Child: The plan involving him and Randall may not have specifically aimed at killing children, but the results of the Scream Extractor seem anything but harmless. Just ask Fungus.

Celia Mae

Voiced by: Jennifer Tilly
"Googly bear!"

A tall and slender, magenta-skinned, and fairly humanoid monster with Gorgon-like features. She has one eye, five purple rattlesnakes that act as her hair, five tentacles as legs, and wears a green, scaly skirt. She works as the receptionist for Monsters, Inc. and is Mike's girlfriend.

  • Ascended Extra: In the Laugh Factory comics, she helps Sulley and Mike take care of Boo.
  • Barefoot Cartoon Animal: In a variation, she has tentacles rather than feet.
  • The Cameo: She makes an appearance in Mike's locker at the end of the prequel. A photo of her appears with her phone number and a note telling Mike to call her.
  • Cone of Shame: Oh yes, she's also subjected into wearing one after her date is ruined because of an 835 call. Even each of her snake hair are also subjected into this. No wonder she's angry at Mike.
  • Cool Big Sister: To Boo in the Laugh Factory comics.
  • Cute Monster Girl: A cute female monster with one eye and purple snakes as hair.
  • Cyclops: Although her "girls" have eyes of their own.
  • Dangerously Short Skirt: She wears a skirt with her outfit, which exposes her long lower tentacles.
  • Four-Temperament Ensemble: Choleric. Though she's very sweet to her boyfriend, she can be hotblooded and is quick to make assumptions. That said, she uses practical resources in the factory to prevent Randall from chasing Mike and Sulley for a little bit in her last appearance before the finale.
  • Gorgeous Gorgon: A gorgon with very playful snakes as hair.
  • Laugh of Love: She giggles upon learning that Mike was able to get a reservation at Harryhausen's for their evening date.
  • Meaningful Name: She's a cecaelia, after all.
  • Ms. Fanservice: She has quite the busty hourglass figure for a monster.
  • Official Couple: With Mike.
  • Pink Means Feminine: She is a very feminine monster with pink skin.
  • Reasonable Authority Figure: In the Laugh Factory comics, at one point, Sulley and Mike come up with an idea that involves using Boo's door as bait to lure out Waternoose, but she has Boo stay safe at her workstation rather than put her in danger.
  • Satellite Love Interest: Aside from being Mike's love interest and the company secretary, she doesn't have much characterization. On her date with Mike they don't really talk about anything but their relationship and it is difficult to see why he likes her so much, aside from the obvious. Not even the prequel bothers to tell us how they first met, as she didn't attend Monsters University like he did. She's only shown briefly as a photograph after Mike begins to work in Monsters, Inc. and starts dating her.
  • She's Got Legs: Her usual outfit shows off her lower tentacles.
  • Slapstick Knows No Gender: Her state after her horrible date with Mike—bruised and stuck not just in one Cone of Shame, but with one for each of her snakes—is treated as comedic.
  • Tiny Guy, Huge Girl: Huge Girl to Mike's Tiny Guy.
  • Tsundere: Celia is Type B, with a sweet "deredere" default.
  • Vertebrate with Extra Limbs: She has five legs.
  • We Need a Distraction: When she sees Mike and Sulley running by with Boo, being chased by Randall. Celia has no idea what's going on, but she buys them some time by making a fake announcement over the mic that Randall has become the top Scarer, getting him mobbed by a horde of monsters as they congratulate him.
  • Woman Scorned: She really starts to lose her cool when her date with Mike is ruined. At least up until they reconcile.

Each spoiler regarding the character below will be left unmarked. You Have Been Warned.

"Wazowski, you didn't file in your paperwork last night."

An elderly, bespectacled, slug-like monster with yellow skin, grey hair who wears a red shirt. She arranges the paperwork for the Scare Assistants, most notably those that work on Scare Floor F. It turns out that she is Agent number 1 of the CDA, who started working undercover at Monsters, Inc. two and a half years ago prior to the film's events to uncover a rumoured conspiracy regarding the company.

  • Big Good: Number 1 agent of CDA who was trying to capture the guy who they suspected committed crimes at MI, aka Waternoose.
  • Chekhov's Gunman: Appears at the end to reveal herself as the Reverse Mole.
  • The Cameo: Shows up as head of the CDA after Mike and Sulley's trip to the human world in Monsters University, telling them that she's always watching.
  • Clerk
    From DVD bonus material: "The pink copy [of your carbonless copy paper scare receipt] goes to accounts receivable. The fuchsia copy goes to purchasing. Ivory goes to your immediate supervisor. And I! Get! The goldenrod! Goldenrod!"
  • Cool Old Lady:
    • Who knew that behind a boring and sarcastic clerk, was actually a reasonable leader of this universe's equivalent of The Men in Black?
    • She counts in the Hilarious Outtakes too due to her constantly messing with the filming for laughs.
  • Deadpan Snarker: "Your stunned silence is very reassuring."
  • Foreshadowing: She stoically closes her window when the CDA makes their first appearance.
  • Four-Temperament Ensemble: Leukine. She is generally a neutral presence for the majority of the movie, neither a threat nor an aid for Sully and Mike, but she ends up being one of the good guys by the end.
  • The Gadfly: The outtakes in the credits portray her as this on-set.
  • Jerk with a Heart of Gold: She is quite outwardly sour and holds a grudge against Mike for most of the film because of his failure to file his paperwork. She also proves to be a good Reasonable Authority Figure to Sulley when she learns about Boo and allows him five minutes to properly say goodbye to the child before they have to shred her door so she wouldn't reenter the monster world, and takes the time to have a bit of fun during the outtakes.
  • Late-Arrival Spoiler: Watching Monsters University before Monsters, Inc. will spoil the fact that Roz is a CDA agent.
  • Non-Mammalian Hair: A large slug-like monster with a tuft of hair on her head.
  • Only One Name: One of the few named monsters without a confirmed full name.
  • Perpetual Frowner: Every time she shows up in the film, she is frowning dourly. That doesn't stop her from joking around in the outtakes, though.
  • Pet the Dog: She shows some semblance of sympathy for Sully not being able to see Boo again after sending her home and allows him five minutes to say his goodbyes.
  • Reasonable Authority Figure: In spite of being the head of an organization that is ridiculously paranoid in dealing with humans and hearing the many false horror stories about them, Roz's first inclination upon meeting Boo is to send her safely back to the human world. She also gives Sully five minutes to say goodbye to Boo before the CDA has to shred her door.
    Sully: I just...want to send her home.
    Roz: ...Very good.
  • Reverse Mole: It turns out that she is the Agent #001 of the CDA.

Jeff Fungus

Voiced by: Frank Oz
"I'm sorry, Wazowski, but Randall said I'm not allowed to fraternize with victims of his evil plot."

A pill-shaped, bespectacled, three-eyed monster with chicken-like legs, red skin, and an orange fin on his back. He works as Randall's assistant and is a supporting antagonist.

  • Anti-Villain: He's only a "bad guy" for being Randall's assistant.
  • Apologetic Attacker: He apologizes to Mike for not being allowed to "fraternize" with him while he's captured, and in general seems to just go along with the evil plan because Randall is commanding him to.
  • Butt-Monkey: From Randall - every appearance of his involves him getting threatened, beat on, or otherwise dumped upon by Randall in some way.
  • Cephalothorax: Like Mike and many other small monsters, his head and his body are pretty much the same thing.
  • Chuck Cunningham Syndrome: Although almost every prominent character in the first film (aside from Mike, Sulley, and Randall) simply appears as a cameo in Monsters University, Fungus is unfortunately one of the rare exceptions. He doesn't appear in the prequel in any way.
  • Extra Eyes: He has three of them.
  • Extreme Doormat: Always does what Randall wants him to do out of fear. He never stands up to his boss, and Fungus isn't involved in Randall's defeat whatsoever. When his coworker gets banished, Fungus' proper reaction is never seen.
  • Four-Fingered Hands: Like several other monsters.
  • Four-Temperament Ensemble: Melancholic. He has no backbone when it comes to being an assistant to Randall, and often bumbles around awkardly.
  • The Igor: He does as Randall commands, such as running the extractor machine.
  • Last-Name Basis: Calls Mike by his last name. This also applies to Fungus himself, who is never called by his apparent given name of Jeff.
  • Minion with an F in Evil: Randall's cowardly, not so evil henchman.
  • Nice Hat: Fungus is never seen without the blue Monsters, Inc. hardhat aside from one singular frame.
  • Punch-Clock Villain: It's hinted at several points that he only works for Randall because he's genuinely afraid of him. Given his treatment at Randall's hands, it's easy to see why he's afraid.
  • Throw the Dog a Bone: When the factory goes from scares to laughs, Fungus really enjoys the change.

George Sanderson

Voiced by: Sam Black
"Keep the doors coming Charlie, I'm on a roll today."

A large monster with orange fur, yellow stripes, and a singular horn on his forehead. He works as a Scarer for Scare Floor F, and is the victim of a series of accidents regarding human accessories.

  • Butt-Monkey: Victim of two 2319 calls, the first one leaving him shorn and sporting a Cone of Shame for the rest of the movie. He's also the one who's tested for cheating with anti-poison gel in the prequel, earning him a puffed-up leg. Further, according to the comics, his body makes a "defense mechanism" by producing a smell that smells like daffodils. This is seen as gross, since what humans perceive as smelling bad is what is considered by monsters to smell good.
  • The Cameo: George appears in the Monsters University as a member of the fraternity Jaws Theta Chi. Funnily enough, when JTC get disqualified for using protective gel, he’s the one who gets used as an example, proving that he still can't avoid being the butt of a joke. He also appears at the end of movie when Mike and Sulley start their first day as a scare team.
  • The Chew Toy: Most of his appearances in both the first and prequel films are being subject to unpleasant experiences, in particular two cases of being shaved and "sanitized" after contact with human objects.
  • Cone of Shame: Infamously wears one after getting his fur shaved and decontaminated by the CDA.
  • The Dog Bites Back: Near the end, he's had enough and just pushes his co-worker into the door before he can be "sanitised" again.
  • Dumb Jock: In M.U., he was part the not very bright Jaws Theta Chi material.
  • Four-Fingered Hands: Like several other monsters.
  • Horned Humanoid: As human-like as a monster can get, and has a horn.
  • Iconic Item: You will very rarely find a piece of merchandise with George Sanderson on it that doesn't feature the infamous white sock on his back. Even in his official artwork, once the model rotates, has the sock stuck on his back.
  • Jerk Jock: Subverted. He was part of the Jaws Theta Chi, but during the scene of Oozma Kappa's humiliation at the ROR house, he is the only member of his frat who looks distraught at what's going on. Word of God says, "he's a good kid in the wrong frat."
  • Power Walk: Is one of the participants of the one found in the first film.
  • Phrase Catcher: "2319! We have a 2319!"
  • Running Gag: Him coming into contact with human items and his assistant Charlie panicking about it.

Ms. Flint

Voiced by: Bonnie Hunt

A pinkish-orange snakelike monster with fins attached to back of her eyes (which are on stalks), who works as a supervisor of the Scare Simulator, where potential Scarers try out the skills.

  • Sassy Secretary: Not quite a secretary, but definitely sassy.
  • Snake People: She resembles an anthropomorphic snake.
  • Surrounded by Idiots: She expresses frustration towards Bile for his poor performance, as well as her pupils for failing to explain what Bile did wrong.
  • Sugar-and-Ice Personality: Comes off as cold at first, but enthusiastically claps for Sulley when he gives his demonstration.

Smitty and Needleman

Voiced by: Dan Gerson

A pair of teenage, geeky monsters with gawky voices that frequently crack. They work as maintenance workers at Monsters, Inc. and admire the Scarers, especially Sulley. Smitty is the short and stout, slug-like one with brown fin-like hair, braces, khaki green skin, and four arms. Needleman is the taller and slim one, with a brown and beige body, a large, round brown nose, and a general lanky physique.

  • Ascended Extra: On a meta level. Despite being minor characters in the film that have little relevance to the plot, they are amongst the most frequently seen Monsters, Inc. representatives in the Disney Parks. Needleman was even part of the Monsters, Inc. section of the Pixar Play Parade before it was revamped to accommodate the release of Monsters University.
  • Chuck Cunningham Syndrome: Alongside Boo and Fungus, they are two of the few characters to be prominent in the first film in some way that don't appear in any form in the prequel. However, they are teenagers, so when Mike, Sulley, Randall, and George were in college, they were only babies at most.
  • Fat and Skinny: Smitty is the Fat to Needleman's Skinny.
  • Four-Fingered Hands: Both of them have those.
  • Geek Physiques: Representing both the "short and fat" (Smitty) and "tall and lean" (Needleman) sides.
  • Heterosexual Life-Partners: Considering how they never interact with anyone else on their own but each other, they clearly have a really close relationship.
  • Manchild: Both of them act childish, but it's understandable because they're not adults yet. Needleman is a special case, since according to a conversation they have, his mom still punishes him by sending him to his room.
  • Nice Hat: Like several employees, they are always seen wearing the blue Monsters, Inc hardhat.
  • Only One Name: They are one of the few named characters that are only known by one name, and it is unconfirmed if they go by their surnames, given names, or nicknames.
  • Plucky Comic Relief: All of their scenes are meant to provide humour, even in more tense ones like Sulley mistaking the fake eye stalk in the trash compactor for Boo.
  • Those Two Guys: They're never seen apart, they have similar voices, and they never interact individually with characters that are not each other.
  • Vertebrate with Extra Limbs: Smitty has four arms.

"2319! We have a 2319!"

A turquoise monster with snail-like eyes and seven tentacle limbs (five of them being legs) that works as George's scare assistant.

Thaddeus "Phlegm" Bile

Voiced by: Jeff Pidgeon

The very first monster seen in the movie. He has a bloated physique, a greyish-blue colour scheme, an Ankylosaurus tail, several pink spikes on his body, and four pink tentacle-like arms. He is a trainee Scarer who is very clumsy in his attempts at scaring children.

  • Brick Joke: One that takes the entire movie to pay off, no less! At the start, his Epic Fail of a scaring attempt involves him slipping on a soccer ball and landing square on a bunch of jumping jacks. At the end, after the switch to laugh power, he's seen coming out of a door with...what else but a soccer ball, and jumping jacks stuck in him?
  • Character Development: Gets braver and able to tank more pain as the film progresses.
  • Chuck Cunningham Syndrome: He doesn't appear in the prequel, nor is he mentioned. Given he's a trainee scarer in Inc., it's likely that he was simply a child during the events of University.
  • Establishing Character Moment: In his first scene, he almost successfully scares the robot child, but its screams scare him too, making him trip over several toys in the room.
  • Epic Fail: Not only does he keep the door open when he enters the robot child's room, but he trips on a soccer ball, a skateboard, and lands on a bunch of jacks, making him scream in pain. Still he at least managed to get a scream out of the animatronic, his second attempt, while lacking the slapstick failure of the first, goes even worse with his "snake/ninja approach with a little hissing" putting the animatronic to sleep. Suffice to say Waternoose was not amused.
    Waternoose: No no no no no, what was that? You're trying to scare the kid not lull it to sleep!
  • Screams Like a Little Girl: When startled by a child animatronic and when he gets some jacks stuck in his bottom.
  • Throw the Dog a Bone: He gets an actual job at Monsters, Inc. once the company switches from screams to laughter.
  • Took a Level in Badass: Starts out as being afraid of even animatronic children and a wimp who Screams Like a Little Girl when jacks get stuck in his bottom. Then when we see him in the middle of the film, he's no longer afraid of the child animatronic, though his attempts at actually scaring it are still poorly. Then by the end, he has incorporated getting jacks stuck into his backside simply to make children laugh.
  • Vertebrate with Extra Limbs: He has four arms.

Jerry Slugworth

"We're on in seven, six, five, four, three, two..."

A humanoid monster with red skin, blue stripes around his body, vertical spikes that resemble hair, and seven digits on both hands. He works as the supervisor for Scare Floor F, and announces when scaring starts and when it ends.

  • Chuck Cunningham Syndrome: He doesn't appear in the prequel, not even in one of the photos in the montage at the end.
  • Four-Fingered Hands: He has seven digits on his hands.
  • Horned Humanoid: One of the most blatant human-like monsters, who also has a bunch of horns that serve as "hair."
  • Nice Guy: He is very amicable, especially towards Sulley.

Other Scarers

Voiced by: Joe Ranft (Claws), unknown (Lanky & Ricky)

Background characters with little to no actual purpose to the story. All of the other Scarers seen in the film work on Scare Floor F alongside Sulley, Mike, Randall, Fungus, George, and Charlie.

  • The Cameo: All of them appear during the credits of Monsters University, in their own Scare Cards, with the exception of Harley Gerson (the armless, orange one with a large jaw).
  • Cowardly Lion: All of them panic upon seeing Boo at the restaurant. Harley is the worst case. Bonus features on the DVD claim that Harley is scared of dogs, cats, and squeeze toys.
  • Extra Eyes: Ted Pauley, the purple monster with gigantic, apelike fists, has sixteen removable eyes. His cousin, Joe "JJ" Ranft has three.
  • Four-Fingered Hands: All of them with fingers have those.
  • Funny Octopus: Rivera, the tall and slender monster with orange skin and eyes on stalks, whose limbs are tentacles, and Harry “Bud” Luckey, whose appearance consists of a head/body covered in purple fur and dark turquoise tentacles.
  • Meaningful Name: Pete "Claws" Ward, a blue, crocodile-like monster with a retractable set of claws, Nicholas “Lanky” Schmidt, a pink monster with very long limbs, Bob "Dentures" Peterson, a light blue dinosaur-like monster with a removable set of sharp teeth, and Augustus “Spike” Jones, a red, slug-like monster with a set of retractable spikes on his back.
  • Power Walk: Alongside Sulley, Randall, and George, they participate in one when they enter the scare floor.
  • Reptiles Are Abhorrent: Bob Peterson and "Claws" Ward obviously try to project this to kids that they scare.
  • Shout-Out: With the exception of Ricky Plesuski, all of these monsters are named after Pixar employees.
  • Vertebrate with Extra Limbs: Rivera has six arms and four legs, Ricky (the green one with eyes on stalks and a large mouth for a body) has eight, crab-like legs, and Bud Luckey simply has six limbs.
  • The Voiceless: With the exception of Claws, Ricky, and Lanky, none of them say a word throughout the movie. Although the rest of them (except JJ Ranft) make brief, but clear noises throughout the film.

Scare Assistants

Voiced by: unknown (Chuck, Frank, and Betty)

Background characters who work as scare assistants on Scare Floor F.

  • Cyclops: Frank, a green, four-armed monster with a ruff of brown fur, has one singular eyeball on a stalk. Harley's assistant, whose body consists of a turquoise eye on a stalk and teal, crab-like legs, also counts.
  • Cephalothorax: Betty, a blue pill-shaped monster, and Ricky's unnamed assistant, a green, Picasso-faced monster.
  • Extra Eyes: Two slug-like monsters, one yellow and one red, have five eyes. Ricky's assistant has three eyes. Waxford, Spike's assistant, is a green monster with small tentacle limbs and five eyes on stalks.
  • Four-Fingered Hands: Frank, Chuck, Betty, and Ricky's assistant have those.
  • Nice Hat: All of them wear the blue Monsters, Inc. hardhat.
  • Two Girls to a Team: Betty and Marge,a pink starfish-like monster, are the only female employees in the movie to work on a scare floor.
  • Vertebrate with Extra Limbs: Frank, with his four arms, and Chuck, a pinkish-beige toad-like monster with four arms.
  • The Voiceless: With the exception of Frank, Betty, Marge, and Chuck, none of them say a word throughout the movie.

    Abominable Snowman

The famous white-furred monster of Himalayan folklore, whose presence in the human world is apparently due to the monster world exiling him. He now spends his life living in a cave in the middle of a cold, snowy mountain, while making snow cones to pass the time.

  • Bigfoot, Sasquatch and Yeti: His name is what he is.
  • The Cameo: He used to work in the mail room at Monsters Inc. along with Mike and Sulley, and warns them that tampering with mail is a crime punishable by banishment.
  • Chekhov's Gunman: Is offhandedly mentioned by Mike as one of the many monsters who got banished, but later shows up when Mike and Sulley get banished to the Himalayas.
  • The Exile: He lives in exile in the Himalayas and meets Mike and Sulley when Waternoose exiles them.
  • Four-Fingered Hands: Like several other monsters.
  • Gentle Giant: He's even bigger than Sulley, but is nothing but helpful to him and Mike when they get trapped in the Himalayas.
  • Ink-Suit Actor: His facial expressions give him a striking resemblance to Ratzenberger.
  • Ironic Name: He lampshades it. He's called the Abominable Snowman, but he's probably the biggest Nice Guy in the movie. In more than one sense.
  • Large Ham: He is very expressive when he talks, especially when he tells stories about Bigfoot, or when he praises the Himalayas after Mike calls them a "frozen wasteland".
  • Noodle Incident: Whatever got him banished to the Himalayas. It's implied he tampered with the Monsters Inc. mail. But how and why is never seen.

    The CDA
"We can neither confirm nor deny the presence of a human child here tonight."

Short for "Child Detection Agency", this group of yellow Hazmat suit-wearing monsters has the responsibility of eliminating all traces of human objects present in the monster world. Their methods of decontamination are often painful, and they will take extreme measures to prevent the spreading of human toxicity.

  • Cyclops: Some models imply that several CDA agents are among the many one-eyed inhabitants of Monstropolis.
  • Decontamination Chamber: They use portable ones to decontaminate subjects that set off a 2319.
  • Everyone Has Standards: Bringing objects from the human world into their world, even by accident, is a serious crime. Kidnapping children and planning on doing them harm? A bigger crime that they're willing to overlook the other one over.
  • Extra Eyes: The visors on some models imply that some of them have three eyes, and perhaps more.
  • The Faceless: All of them wear yellow bio-hazard suits, although because they're monsters, their body shapes vary quite a bit.
  • Failed a Spot Check: Despite their entire purpose being to prevent humans and their objects from contaminating the monster world and being paranoid enough to attack anyone even remotely suspcious, they repeatedly fail to realise Sulley and Mike are the ones harbouring the human child.
  • Fast-Roping: Several CDA members enter the Scare Floor like this. During the Hilarious Outtakes one CDA agent accidentally splats against the window instead of opening it.
  • Hazmat Suit: They all wear banana yellow ones.
  • The Men in Black: They act as this to the Monster world.
  • Multiple Head Case: One model represents the only two-headed monsters to be physically present in the movie.
  • Not So Above It All: At one point, Sulley is cornered by two agents...who want his autograph.
  • Number Two: One of the CDA agents is numbered as 00002, which implies heavily that this agent is the 2nd in charge. 00002 is usually the one seen leading and giving the orders to the rest of the CDA.
  • Overreacting Airport Security: The way they react to a 2319 alert is pretty damn over the top.
  • Vertebrate with Extra Limbs: Several of them have four arms. One specific model has six arms.


How well does it match the trope?
