!!Oozma Kappa

[[folder:Don Carlton]]
->'''Voiced by:''' Creator/JoelMurray [[labelnote:Other voice actors]]Peik Stenberg (Finnish), Jean-Claude Donda (European French), Louis-Georges Girard (Canadian French)[[/labelnote]]
[[quoteright:326:https://static.tvtropes.org/pmwiki/pub/images/don_carlton_2_8213.png]]

A middle-aged student and the founding member of Oozma Kappa fraternity.
----
* BackToSchool: Don has joined Oozma Kappa after he was downsized from his sales department. Averted in that none of his humor is about his age, rather than that he's still sticking with his well-polished sales persona and patter in a fraternity environment. This is itself averted [[spoiler:in the final act when it's revealed that he's engaged to his fraternity President's mother; and will now be his big brother as well as a stepfather]].
* CoolOldGuy: He's a friendly, cheerful guy and welcomes Mike and Sulley into the frat with hot cocoa. He also [[spoiler:beats Reggie Jacobs during the Scare Test segment of the Scare Games]].
--> '''Don''': [[InsultBackfire Thanks for "taking it easy on Grandpa"]].
* DiggingYourselfDeeper: See ThatCameOutWrong below.
* IntergenerationalFriendship: Is friends with the other members of Oozma Kappa despite being old enough to be their dad. [[spoiler:Actually becomes literal for Squishy when Don decides to marry Sheri.]]
%%* MeaningfulName
* NiceGuy: Don is fatherly, accepting, gentle, and kind.
* NonMammalianHair: Sort of. His "thinning hair" and [[PornStache mustache]] look like fins, much like many other students on campus.
* TeamDad: Starts out as one for Oozma Kappa and later on [[spoiler: becomes one in a more literal sense for Squishy by getting engaged to his mom]].
* ThatCameOutWrong: [[spoiler:His attempt at making Squishy feel less awkward about him becoming Squishy's stepfather.]]
--> [[spoiler:'''Don:''' Just think of me as your big brother that's marrying your mother... wait. We're brothers that share the same mom/wife. ''(beat)'' [[DiggingYourselfDeeper That's worse]].]]
* WallCrawl: [[spoiler: Don eventually learns to do this by utilizing the suction cups on his arms. He makes effective use of it during the last few rounds of the Scare Games.]]
[[/folder]]

[[folder:Terri and Terry Perry]]
->'''Voiced by:''' Creator/SeanHayes and Creator/DaveFoley [[labelnote:Other voice actors]]Kimmo Vehviläinen and Jarkko Valtee (Finnish), Creator/EmmanuelGarijo and Creator/DonaldReignoux (European French), Sébastien Dhavernas and Gilbert Lachance (Canadian French)[[/labelnote]]
[[quoteright:242:https://static.tvtropes.org/pmwiki/pub/images/terri_and_terry_2_3000.png]]

A two-headed monster with one eye on each head, four arms, and tentacles for legs.
----
* ConjoinedTwins: They both have different personalities, appearances and voices but share the same body. Sadly for Mike, the Greek Council counts bodies, not heads.
* {{Cyclops}}: Both of them, individually
* DeadpanSnarker: Terry, in his and Terri's introduction scene.
-->'''Terry:''' Hi, I'm Terry with a "y".\\
'''Terri:''' And I'm Terri with an "i"! I'm a dance major!\\
'''Terry:''' [[SarcasmMode (laughs) And I'm not.]]
* ADegreeInUseless: Terri is a dance major. But Terry doesn't cooperate.
* FoolishSiblingResponsibleSibling: Terri is foolish while Terry is responsible.
* GenderBlenderName: Terri is presumably male, but has a girl's name.
* HiddenDepths: The serious and cynical Terry can perform close-up magic.
* HumanoidAbomination: [[spoiler: Both briefly make a shadow silhouette that resembles one during the final event in the Scare Games.]]
* IdenticalTwinIDTag: Terri has a single straight upright horn, like an "I", while Terry has two slightly curved downward horns, like a "Y". Also, Terry is taller.
* JapaneseBeetleBrothers: It probably wasn't intentional on the creators' part, but they fit the pattern perfectly.
%%* {{Keet}}: Terri, much to Terry's chagrin.
* MultipleHeadCase: Mike tries to exploit it by passing them off as two members but Brock doesn't buy it. Lampshaded:
--> '''Brock''': Sorry, boss. We count bodies, not heads. That dude counts as one.
* NiceGuy: In spite of their opposing personalities, both twins are well mannered and polite, and have deep, brotherly love for each other.
* PolarOppositeTwins: Terry is calm, cynical, and intellectual, while Terri is energetic, optimistic, and theatrical.
%%* RedOniBlueOni: Terri is the red to Terry's blue.
* RhymingNames: Terry and Terri Perry.
* ThemeTwinNaming: Their names sound the same but use a letter similar to their respective horn designs.
* ThoseTwoGuys: Justified since they ''are'' Conjoined Twins.

[[folder:Scott "Squishy" Squibbles]]
->'''Voiced by:''' Creator/PeterSohn [[labelnote:Other voice actors]]Tuomas Uusitalo (Finnish), Malik Bentalha (European French), Creator/HugolinChevretteLandesque (Canadian French)[[/labelnote]]
[[quoteright:278:https://static.tvtropes.org/pmwiki/pub/images/squishy_2_5239.png]]

A five-eyed jelly monster whose mother owns the fraternity house.
----
* AlliterativeName: '''S'''cott '''S'''ebastian '''S'''quibbles[[note]]As revealed by the FullNameUltimatum his mother gives him in the short ''Party Central''[[/note]]. Also applies when using his nickname.
* AlwaysSomeoneBetter: It's not that evident at first, but he could count as this to Mike. Though conventionally cuter and shorter than Mike, [[spoiler:he ends up becoming an on-field Scarer]]. This is to demonstrate that it wasn't exactly height and appearance that doomed Mike's dreams.
* AmazinglyEmbarrassingParents: His mom, Sheri Squibbles.
* ChekhovsSkill: His tendency to sneak up on people early in the film serves as {{Foreshadowing}}, as [[spoiler:he uses it to his advantage during the Scare Games]].
* DisappearedDad: [[spoiler: Don later marries Sheri. Probably means his biological father left the picture a while ago.]]
* EstablishingCharacterMoment: When introducing himself, he unintentionally startles Sulley, then rather childishly climbs into a rocking chair.
* ExtraEyes: He has five eyes.
* JumpScare: [[spoiler: His tactic used in the final event of the Scare Games when an unsuspecting dummy turns around and finds him creepily staring at it.]]
* {{Keet}}: He is a very energetic and excitable little fellow. He can still be stealthy when he wants to be.
* {{Manchild}}: While still living with his mom isn't ''that'' odd for many college-age students, him never staying up late and making wishes on ladybugs makes him rather childlike in an endearing way.
* MeaningfulRename: Somewhere after the end of the movie, his nickname got changed from "Squishy" to "Scary", as shown on his Scare Card during the credits.
* MommasBoy: Much to his embarrassment. He still lives with his mother who dotes on him, even in front of his friends.
* NiceGuy: Squishy is kind and sweet.
* OffscreenTeleportation: [[spoiler: Later uses this to his advantage in the scare simulator challenge of the Scare Games.]] Overlaps with StealthHiBye. He never uses the stealthy exit, but ''hot damn'' he's got the "Stealth Hi" part down.
* RunningGag: Squishy repeatedly shows up from out of ''nowhere''. [[spoiler: Acts as a sort of ChekhovsSkill later in the Scare Games.]]
-->'''Mike:''' ''We need to get you a bell.''
* StealthExpert: His natural skill is being unnervingly stealthy, which allows him to excel as a Scarer.

[[quoteright:347:https://static.tvtropes.org/pmwiki/pub/images/art_2_7730.png]]

A purple furry monster with an arch shape and a questionable background.
----
* CloudCuckoolander: His appearance alone confuses the hell out of people.
* ADegreeInUseless: He's studying [[NewAgeRetroHippie New Age Philosophy]].
* HavingAHeart: "I have an extra toe. Not with me, of course."
* MysteriousPast: "The ultimate free spirit, Art is a mysterious monster with a questionable background."
* NeverGoingBackToPrison: When spotted by security in the Scare Factory, he completely freaks out at the thought of any legal punishment and screams that he can't go back to prison.
* NewAgeRetroHippie: He fits the mold quite perfectly. He studies "New Age Philosophy" and is overall quite the {{Cloudcuckoolander}} and PluckyComicRelief.
* NiceGuy: He has a good heart, but rather oblivious for the most part.
* NoodleIncident: Whatever got him in jail before.
* OnlyOneName: He is only ever referred to as "Art". Not even in the promotional material is he given any other names.
* PluckyComicRelief: His main purpose in the movie is to provide humor with his hippie personality.

!!Roar Omega Roar
A preppy fraternity comprised only of the cream of the crop in scare students, Roar Omega Roar has won the Scare Games several years running. Sulley was a member with them at the start of the semester until getting thrown out of the Scare Program. Randall Boggs becomes a member of the group for the Scare Games in the film.
----
[[folder:Johnny J. Worthington III]]
->'''Voiced by:''' Creator/NathanFillion [[labelnote:Other voice actors]]Creator/IlkkaVilli (Finnish), Creator/AlexisVictor (European French), Creator/TristanHarvey (Canadian French)[[/labelnote]]
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/johnny_2508.png]]

The confident President of Roar Omega Roar who is Mike Wazowski's rival.
----
* TheAce:
** Much like Sulley, Johnny is a naturally gifted scarer, though it's implied that he lacks Sulley's initial [[BrilliantButLazy tendency to slack off]] and used his past studies to perfect his talent and become a legitimate high-achiever. As a result, he's regarded as the top scarer in the entire university, which further verifies his VillainWithGoodPublicity status.
** Season 2 of ''Monsters at Work'' reveals that he ended up as a Scream King during his time at MU and set new records at the school that weren't broken until Tylor Tuskmon broke them during his time at MU.
* BigBad: Of ''Monsters University'', while he's not truly evil and Hardscrabble is a bigger threat in the greater scope he's the most active threat against Sulley and Mike's rise to the top and their most personal foe there. [[spoiler:He acts as this again come Season 2 of ''Monsters at Work'', where he's attempting to run Monsters Inc to the ground both to ensure [=FearCo=] outlasts them and ruin their reputation for coming close to solving the energy crisis.]]
* TheBusCameBack: He returns in Season 2 of ''WesternAnimation/MonstersAtWork''.
* CapitalismIsBad: [[spoiler:Johnny is, basically, a robber baron that employs lies and the threat of violence to exploit his workers and keep them in constant competition with each other, for his own profit]].
* ClimaxBoss: The movie builds up to Johnny and Mike's eventual face-off towards the end of the movie. However, the movie doesn't end [[spoiler: even after Mike defeats Johnny as it was revealed that Sully tampered with the machine to make it easier for Mike to scare it which Mike becomes distraught about once he finds out, leading to him to stumbling off into the human world to prove himself]].
* EveryoneHasStandards:
** While Sulley's family heritage initially gets him in Johnny's good graces, Johnny soon becomes frustrated with Sulley's failing grades and his nonchalance towards them. He warns Sulley before the end-of-semester exam that his natural talent and the famous Sullivan name alone aren't enough without academic success.
** Following his debate with Sulley on the benefits of Laugh Power on ''I Scream! You Scream!'', Johnny openly acknowledges that the hosts' questions were unfairly biased in his own favor, due to him being a supporter of Scream Power, and he believes that they should have given Sulley more of a chance to explain his stance without vilifying him. [[spoiler:Though following the reveal of his true intentions at the end of the season, it's unclear whether Johnny truly means it or is merely manipulating Sulley as part of his ruse.]]
* EvenEvilHasLovedOnes: While he isn't shown interacting with them much onscreen, in ''Monsters at Work'' Johnny seems to have a healthy relationship with his wife Claire and their two children, at one point complaining that an incoming phone call is making him late for "family game night". [[spoiler:Even with the revelation that Johnny was [[BitchInSheepsClothing manipulating Tylor and the rest of the main cast]] for the entire season, there is no indication that his love for his family is anything less than genuine, and he seemingly makes sure to avoid involving or implicating them in his scheme.]]
* EvilCounterpart: To Sulley, as both are introduced as popular {{Jerk Jock}}s. The difference is that Sulley undergoes CharacterDevelopment and becomes nicer as a result while Johnny sticks to remaining a jerk. [[spoiler:It's even more obvious by Season 2 of ''WesternAnimation/MonstersAtWork'', which reveals Johnny is now the CEO of Fear Co., a rival company to Monsters, Inc]].
* {{Expy}}: Basically Bradley Uppercrust III from ''WesternAnimation/AnExtremelyGoofyMovie'' if he were a monster.
* FatalFlaw:
** His close-mindedness. During college, he arrogantly assumes that Mike and the rest of Oozma Kappa are all nothing but a bunch of losers who don't even have a remote chance of being scary. Thanks to Mike's training, they actually manage to do decently well at the Scare Games and make it into the program afterwards, with Mike going on to [[spoiler:deliver a record breaking scare against Johnny--or so it seemed, as Sulley cheated to make it so Mike's scare would win no matter what.]] While he ultimately was proven right that Mike didn't have what it took to be a scarer, Mike still found his way onto the Scare Floor at Monsters, Inc. thanks to his and Sulley's teamwork, and the duo would go on to become the top team at the company.
** This becomes an even bigger flaw for him during ''Monsters at Work''. When Mike and Sulley successfully transition the company to laugh power, [[spoiler:Johnny is outright furious, and decides to find Randall, and works with him to sabotage M.I. from within. While Johnny puts up a false front where he seems willing to accept laugh power as a potential alternative, he's already made up his mind and deemed that scream and ''only'' scream power is the one true way of the monster world. Even then, he still has Randall steal laugh energy from M.I. and mixes it with his company's scream energy, disguising it as a Scream Enhancer to make it seem as if he's found a solution to the energy crisis. But rather than being hailed as a hero (or nearly turning the city into a crater, since neither energy can mix without becoming unstable), or even accepting that laughter is a more viable energy source, he's exposed as a fraud and hauled off to the slammer.]]
* FauxAffablyEvil:
** While he isn't outright "evil" in ''Monsters University'', Johnny puts on a superficial front of charm and chumminess that only serves to underline how slimy he really is.
** In ''Monsters at Work'', Johnny seems much more genuinely cordial and friendly, in spite of the fact that he's still proudly using Scream Power and exploiting human children without hesitation. [[spoiler:In the season finale, any friendliness he displayed previously is revealed to be nothing more than a front, as he's revealed to be a CorruptCorporateExecutive.]]
* FollowInMyFootsteps:
** Never brought up in the movie proper, but his voice actor, Creator/NathanFillion, [[https://www.youtube.com/watch?v=hQ-TjOOaoTQ believes]] Johnny has been pushed by his father into becoming a high-achiever. Supported in the [[AllThereInTheManual official artbook]], where it's stated that Johnny is deathly afraid of failure.
** Played straight in ''Monsters at Work'', which reveals that Johnny's father was the previous CEO of Fear Co., and since inheriting the position, Johnny is grimly determined to uphold the company's scaring legacy, [[spoiler:even if he has to resort to underhanded and deceitful methods to do so]].
* FormerlyFit: In ''Monsters at Work'', he's shown to have put on a bit of weight since his freshman year of college.
* GloryHound: At the end of the day, glory is all that matters to him. [[spoiler:In fact, his primary motivation for sabotaging Monsters Inc is to remain on top at the expense of others]].
* GracefulLoser: [[spoiler:Possibly. While he never interacts with OK after losing to them, even though he constantly underestimated and belittled them leading to that point, he gets over the shock of their victory fairly quickly and doesn't seem to hold a grudge. He even congratulates and tries to invite Sulley to rejoin his fraternity after their defeat from OK.]]
* HiddenDepths: For much of the movie, his general reaction towards Oozma Kappa has been of disdain, scorn, and smug dismissal of them. However, at the end, when facing off against Mike for their scaring round, he speaks surprisingly frankly and without any of the usual pomp in his voice when he tells Mike that he shouldn't feel embarrassed if he fails, given that he was never meant to be here anyways.
* HateSink: Hardscrabble later proves to have some more genuinely benevolent HiddenDepths and also has the justification of wanting actually qualified candidates for the Scaring program which is, to their knowledge, a highly dangerous job. Johnny is more for the audience to root for Mike and Oozma Kappa to triumph over, and he's the ClimaxBoss of the film as a result. [[spoiler:Season 2 of ''Monsters at Work'' seemingly takes him out of this as he's received significant CharacterDevelopment and now he's reformed from his old bullying ways... Until the finale two-parter reveals he's not only not changed but has gotten worse about everything.]]
* HighCollarOfDoom: Johnny's college outfit includes an orange undershirt with a large, popped collar, fitting his devilish, vampire-like appearance. His business suits as the CEO of Fear Co. maintain this feature.
* HornedHumanoid: He has an humanoid monster appearance but has two big horns on his head.
* HorribleJudgeOfCharacter: After Tylor [[spoiler: goes to work for him at Fear Co.]], Johnny [[VillainRevealsTheSecret decides to reveal]] [[spoiler: he's been having [[ItsPersonal Randall]] sabotage Monsters, Inc. so he can steal their laugh power and mix it in with his company's scream energy to "resolve" a resource crisis of his own making. Johnny arrogantly assumes Tylor's just as morally bankrupt and willing to go along with a scheme of such magnitude or at least desperate enough to do so without qualms; he predictably warns his former coworkers and puts a stop to the scheme.]]
* JerkassHasAPoint:
** While kicking Sulley out of the fraternity is harsh Johnny is completely justified in his assessment that Sulley is mooching off his family legacy and not putting in the effort he needs to succeed on his own merits.
-->'''Johnny:''' It's time to start delivering on that Sullivan name.
** An unpleasant take where in spite of his brutal jerkishness he’s ultimately right that Oozma Kappa lacks the traditional Scarer traits. This leads to them learning to become resourceful about their own seemingly benign traits to become Scarers. Lampshaded by Sulley in a deleted scene:
-->'''Mike:''' Tell them! That guy's a jerk! He's all wrong!
-->'''Sulley:''' You're right. He's a jerk… but I'm ''not'' so sure he's wrong.
* JerkJock: A monster version of the trope but it's clear he’s the popular guy on campus who’s thought as cool by everyone. Yet he values academic performance as well as sports prowess.
* JerkWithAHeartOfJerk: The only reason he invited Oozma Kappa to the fraternity party during the Scare Games was to humiliate them, not congratulate them. [[spoiler: In Season 2 of ''Monsters at Work'' he gives Tylor an offer to work for him to help his family and acts cordial to Sulley and Mike despite their past hang-ups and being rivals… Only so Randall could pull sabotage from behind the scenes with them none the wiser. Once the chips are down he proves he's still the same petty jerk as before.]]
* KarmaHoudiniWarranty: [[spoiler: Though he and his fraternity lost the Scare Games to Oozma Kappa this is made moot when it’s revealed this only happened because Sulley cheated by tampering with Mike's settings in the final challenge which he eventually admits to. Johnny himself faces no consequences for being a jerk and eventually gets a job at Fear Co. where he eventually became the CEO. Upon his return in ''Monsters at Work'' Season 2 though it’s eventually revealed he’s been sabotaging Monsters Inc. via an alliance with Randall and stealing their Laugh power while passing it off as his own Scream power. His luck finally runs out when MIFT thwarts him and Randall and exposes his corruption, resulting in his arrest.]]
* KnightOfCerebus: [[spoiler: ''Monsters at Work'' had been a generally light-hearted WorkCom since the first season and well into the second one despite the higher stakes, but when Johnny reveals his true colors, the Season 2 finale treats him ''very'' seriously, and he proves to be genuinely menacing who is unfettered in his methods and whose goals threaten to destroy all of Monstropolis]].
* MeanBoss: ''Monsters At Work'' shows that in contrast to Sulley, who's a BenevolentBoss as CEO of Monsters Inc, Fear Co. is an extremely oppressive and toxic work place that still uses the scare board to instigate competition among the scarers, they only get 15 minutes of lunch and their scare room is windowless in contrast to the well-lit Monsters Inc. And any scarer that's late or fails to put up good numbers is terminated.
* MirrorCharacter: ''Monsters At Work'' places him as one to [[spoiler:Waternoose, as both were high-class CEO's who ran major energy companies, were the third member of their family line, and were using Randall to commit morally dubious deeds to protect scream power as a viable energy source. However, whereas Waternoose was a WellIntentionedExtremist who was willing to kidnap children and torture them because he was desperately trying to solve the energy crisis and protect his company, Johnny was willing to sabotage Monsters, Inc. and steal their laugh power to mix with his own scream power because Mike and Sulley's success bruised his ego. Moreover, while Waternoose did his best to keep Sulley out of it until he found out and was forced to banish him, Johnny brought Tylor into the fold of his scheme and got brought down as a result. For added irony, Johnny winds up becoming Waternoose's cellmate.]]
* MoneyDumb: [[spoiler:Johnny's business could've been a lot more successful had he not treated his workers as borderline slaves, as he could’ve had a happier, healthier, and genuinely loyal workforce producing even more money profit. As ruthless and cunning as Johnny is, this just shows how dumb he really is as far as understanding what makes for a good business model]].
* TheNicknamer: Examples include "Killer", "Big Blue", "Bruiser", and "Grandpa". He also latches onto "Sulley" immediately when he's told that's his current conversation partner's preferred address. Which says a lot when you consider that Randall is just "Boggs" to him.
* NotSoHarmlessVillain: At first, he was just the garden variety JerkJock college rival who flaunts his status, [[spoiler:but by Season 2 of "Monsters at Work", he's a sadistic corporate shark willing to sabotage others to get ahead]].
* ObviouslyEvil: His rather devilish appearance should be a big hint that he's not a nice guy. [[spoiler:He ''seems'' to get better in Season 2 of ''Monsters at Work'' until the season finale reveals he's not, sending back into this trope.]]
* OfficialCouple: ''Monsters at Work'' reveals that, in the years since they graduated from MU, he married Claire Wheeler and they now have two kids.
* OpposingSportsTeam: The closest thing the prequel movie has to a main antagonist.
* PreppyName: As befitting his background as an upper-class snob, he has a fancy family name that also shows him to be the third member with that name.
* TheRival: Serves as Mike's main one in the movie. They even face off against each other in the final round of the Scare Games.
* RivalTurnedEvil: [[spoiler:By ''Monsters At Work'', he's become a full-blown villain who seeks to run Monsters Inc out of business and sabotage Mike and Sulley's success]].
* RunningOnAllFours: Johnny is occasionally seen running on all fours during some of the Scare Games, such as the Simulated Scare challenge.
* {{Sadist}}: [[spoiler:He defends the act of scaring children as a matter of course. His belief is that as monsters, it's in their nature to be scary. Despite these claims, it's very clear he ''enjoys'' tormenting others, be it his own workers or human children]].
* SmugSmiler: He usually has a big prideful grin on his face.
* SmugSnake: As great as he is at scaring, he is too overconfident on his skills and doesn't think Mike can compare to him.
* TookALevelInKindness: In Season 2 of ''Monsters at Work'', Johnny seems much more cordial and respectful to both Sulley and Mike, even when he disagrees with Monsters. Inc's change to Laugh Power, though Mike still holds a grudge from their college days. [[spoiler:{{Subverted|Trope}} in the Season 2 finale, which reveals that Johnny's niceness has all been a front, and he's actually even ''[[TookALevelInJerkass worse]]'' than he was in his college days, having gone from simply being a mere {{Jerkass}} to being a full-blown villain, deliberately conspiring with Randall to sabotage Monsters Inc.]]
* TopHeavyGuy: The lower half of his body is much smaller than his upper half.
* VillainWithGoodPublicity:
** As Mike's arch-rival and the ringleader on the effort to humiliate Oozma Kappa, he is loved and respected by pretty much everyone in the university. But then again, who could blame him? Being the president of the top fraternity in the most prestigious university in the monster world and all.
** [[spoiler:In ''Monsters at Work'', Johnny is now the highly respected CEO of Fear Co., and while he initially seems to have TookALevelInKindness, the season finale reveal that he's actually a CorruptCorporateExecutive. Fortunately his luck finally runs out and he's outed for his corruption in the end, getting arrested like Waternoose before him.]]

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/chet_alexander_2_9725.png]]

A one-eyed crab monster that serves as the Vice President of Roar Omega Roar.
----
* AmbiguouslyGay: He is seen often following Johnny than most members of the fraternity [[spoiler:and when Johnny gets a high score during the last challenge of the Scare Games, he yells at him "Johnny, you're my hero" in a way that a straight person would surely not yell to a friend when congratulating him]]. In ''Monsters at Work'', [[spoiler:though some of his clinginess to Johnny can be explained by the reveal of him being a secret MERC agent]], he is also constantly complimenting Johnny, is "overprotective" of him, and it's implied he's desperate for his attention, which would've been the case for more than a decade at this point.
* {{Cyclops}}: Another one-eyed monster in the series.
* TheDragon: To Worthington. This continues into their adult years where he's an employee at Fear Co. under Johnny's authority [[spoiler:until he betrays Johnny and helps MIFT stop his and Randall's evil plan and reveals his nature as a MERC double agent]].
* EvenEvilHasStandards: [[spoiler:While he may have been happy to help Johnny with their bullying in their younger years and sided with him and Scream Power in their adult years, even Chet recognizes that Johnny working with a banished monster like Randall and enacting a scheme to steal and mix Laugh Power with Scream Power is going too far. This is why he infiltrates his scheme as a MERC agent and betrays him at the last second by using Randall's tail as a plug for the Scream Extractor.]]
* GiantEnemyCrab: He's not the biggest of the [=ROR=]s, but he ''is'' much bigger than most normal crabs, and is an antagonist for Mike, Sulley, and the other Oozmas.
* HeelFaceTurn: [[spoiler:During the climax of ''Monsters at Work'''s second season, Chet betrays Johnny to help MIFT stop his and Randall's evil plans and even reveals that he was secretly working against Johnny the entire time as a MERC agent.]]
* MistreatmentInducedBetrayal:
** [[spoiler:In the second season finale of ''Monsters at Work'', Chet is revealed to be an undercover MERC agent reporting to Roz on Johnny's activities. Given his remark that Johnny should have treated his assistants better, it is heavily implied that Chet was an assistant first and was then recruited by MERC due to Johnny's years of dismissing and looking down on him.]]
** [[spoiler:Played even straighter against Randall, who spends much of the Season 2 finale belittling and mocking Chet, even calling him his old college nickname, "Chet Wetter", clearly making Chet uncomfortable while Johnny gladly allows Randall's bullying to continue. When Randall has the upper hand against the MIFT team at the end of the episode, Chet electrocutes Randall and uses him to re-power the Scream Extractor, finally getting payback for all the abuse he's endured.]]
-->'''Chet:''' That's for all the bed-wetters out there.
* NiceJobFixingItVillain: [[spoiler:If Chet hadn't casually mentioned to Mike after he and the rest of Roar Omega Roar humiliated them at a party that they weren't cut out "for the big leagues", Mike wouldn't have gotten the idea to take Sulley and the rest of the Oozma Kappa members to Monsters Inc. to cheer them up, show them that all kinds of monsters are scarers, and thus provide them the encouragement they needed to proceed forward in the Scare Games.]]
* RedBaron: We see in the credits that he is known as "The Claw".
* SpeechImpediment: Speaks with a noticeable lisp.

[[quoteright:126:https://static.tvtropes.org/pmwiki/pub/images/claire_2_51.png]]

President of the Greek Council and announcer of the Scare Games. In ''Monsters at Work'', she is now married to Johnny Worthington III, making her full name Claire Wheeler-Worthington, and has two kids with him.
----
* CuteMonsterGirl: She looks kind of cute for a monster with three eyes.
* TheEeyore: Played with. She says discouraging words to Mike so he won't participate into Scare Games while she's also announcing Scare Games to Mike and many other students. This is opposed to what her partner Brock's doing, in which he says encouraging words instead. However, it's pretty much likely a case of JerkassHasAPoint, that Mike isn't scary, just like many other monsters have said.
* ExtraEyes: Has three eyes.
* {{Goth}}: She appears to be one in her college years, wearing heavy makeup, dark clothes and having a deadpan, uncaring attitude. Her older self in ''Monsters at Work'' seems to have grown out of it.
* NonMammalianHair: Like Don, her hair looks more like fish fins or webs.
* NotSoStoic: After being half-asleep while commentating through most of the Scare Games, [[spoiler:she goes ''ballisticly happy'' when Oozma Kappa wins the final event]].
* OfficialCouple: ''Monsters at Work'' reveals that, in the years since they graduated from MU, she married Johnny Worthington III and they now have two kids.
* OneSteveLimit: The prologue of the film has a younger Mike mentioning a girl in his kindergarten class named Claire, [[TheGhost though she doesn't appear on screen]]. This more prominent Claire who appears in the rest of the film is seemingly not the same character.
* RedOniBlueOni: The blue to Brock's red.
* SavvyGuyEnergeticGirl: {{Inverted}}. She's the Savvy Girl to Brock's Energetic Guy.
* ShipTease: With [[LovableJock Brock Pearson]], though by the time of ''WesternAnimation/MonstersAtWork'', she has married Johnny Worthington III and had two kids with him.

The Greek Council's Vice-President and co-announcer for the Scare Games.
----
* CharacterCatchphrase: "'''THE SCARE GAMES!!!'''"
* EightiesHair: He has feathers on his head styled like a mullet.
* FeatheredFiend: Downplayed. He's a bird monster, but other than the fact that he's supposed to be scary, he's a pretty nice guy.
%%* LargeHam
* JaggedMouth: More like jagged beak.
* LargeHamAnnouncer: He's one of the announcers for the Scare Games and he speaks in loud, dramatic tones.
* LovableJock: While he's definitely a yeller, he's nice enough to give encouraging words to Mike before he signs up for the Scare Games.
* MixAndMatchCritters: He looks like a giant purple chicken with the horns of a gazelle.
* NoIndoorVoice: [[spoiler: Inverted temporarily during one of the Scare Games events inside a library. Once the Oozma Kappa members make noise, though, he goes back to his normal level.]]
* RedOniBlueOni: The red to Claire's blue.
* SavvyGuyEnergeticGirl: {{Inverted}}. He's the Energetic Guy to Claire's Savvy Girl.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/carrie_9795.png]]

A three-eyed pink monster with red hair who is the fearless President of Python Nu Kappa.
----
* AlphaBitch: Implied. While she has very little characterizations, she's the closest example you can get in this universe.
* BrainlessBeauty: As attractive as she and her team look for monsters, they do not seem terribly smart in the "Don’t Scare the Teen" challenge judging by how they all scare humans who are clearly teenagers.
* CuteMonsterGirl: Carrie and the rest of her team have more attractive traits than other monsters, including some of the female ones we see.
* EstablishingCharacterMoment: Carrie and PNK are introduced being wished good luck by Terry. Carrie responds in a cheery voice, "Thanks! We're going to rip you to pieces!", then flashes her NightmareFace.
* EvilRedhead: To the very least, she is more than likely to be evil to human children, just like many other monsters in this universe. Also, see ManipulativeBitch below.
* ExtraEyes: Three.
%%* EyeBeams
* InexplicablyIdenticalIndividuals: All the PNK girls look identical, despite not being biologically related.
* ManipulativeBitch: Possibly. [[spoiler:OK would not have been aware of the party at [=ROR=] if Carrie and PNK hadn't told them about it, and OK attending the party ultimately results in them falling victim to a particularly cruel joke from the [=RORs=]. While not explicitly stated, some fans believe that the rest of Frat Row knew about the prank from the start, which would mean that Carrie and her sorority deliberately led OK into the trap.]]
* NightmareFace: In a second, she can reveal red eyes and a mouth full of sharp teeth.
* PaletteSwap: As mentioned above, all the PNK girls look physically identical. They can only be told apart by their skin color, hair color, and outfit color.
%%* PinkMeansFeminine
* RedEyesTakeWarning: [[EyeBeams Can shoot fire out of them, too]].
* ShootEverythingThatMoves: What screws her team over during the "Don't Scare the Teen Event". Participants are only supposed to scare young children.
* SuccubiAndIncubi: She and the rest of the PNK sorority resemble succubi. Even more prevalent in their visual development artwork.

A slug student who attempts to get to all his classes.
----
* BrickJoke: [[spoiler: Shows up after the credits as he finally makes it to his classroom, which is empty.]]
* ButtMonkey: Is late to his first day of class, [[spoiler: by two whole semesters. He now works at Monsters Inc, and he ''still'' takes so long to get to places. He took a ''whole night'' to complete his approach for his bowling team]].
* EyeOnAStalk: He is a slug monster with eyes like this.
* GoofyBuckteeth: He is a gag character with buck teeth.
* NoNameGiven: Stands out for being one of the few characters in the movie not to be named, not even in extended material.

[[quoteright:243:https://static.tvtropes.org/pmwiki/pub/images/dean_hardscrabble_2_6885.png]]

The dean of the School of Scaring.
----
* ArmorPiercingQuestion: Hardscrabble gives one regarding Mike that Sulley (despite starting to warm up to Mike) can't give a straight answer to.
-->'''Hardscrabble''': Do you think he's scary?
* BerserkButton: Surprisingly subverted. [[spoiler:When her record-breaking scream canister is introduced, and summarily knocked over and broken, it seems as though Hardscrabble is about to enter DissonantSerenity mode and hardly call out Mike and Sulley. But she doesn't. She's disappointed, but she never so much as raises her voice.]] Having said that, she ''does'' [[spoiler:give both Mike and Sulley a TheReasonYouSuckSpeech, instead of giving them a fair go in the scare simulator]].
* BigEntrance: She ''loves'' doing this trope. Anytime she's shown flying into the scene, ''everyone'' noticeably becomes nervous and on edge. In particular, her introductory scene leaves absolutely '''no''' room for discussion about her qualifications as a Scarer.
* ChuckCunninghamSyndrome: Although ''Monsters at Work'' has the characters revisiting Monsters University in several episodes, Dean Hardscrabble is never seen or mentioned, not even in the Season 2 premiere when Tylor and other famed graduates from the school are presented to the crowd. Given the [[DistantSequel significant time skip]] between the film and show, it is possible that Hardscrabble has either retired from her position or passed away, though neither is confirmed. The former is definitely possible considering the Monster World is transitioning to laugh power, and because scaring will eventually become obsolete, she will have all but served her purpose.
* CoolOldLady: She's a SternTeacher and RetiredBadass, after all.
* CreepyCentipedes: Her bottom half.
* DeanBitterman: [[spoiler: She gets better.]]
* EstablishingCharacterMoment: Hardscrabble's first scene has her swoop into the classroom, pull down all the curtains and make the room very dark, stand by her bust and trophy to show her earned credentials, and give a stern lecture about how she expects only great things and anyone substandard will fail.
* {{Expy}}: A bit of a DistaffCounterpart to Anton Ego from ''{{WesternAnimation/Ratatouille}}''.
** According to an interview, Hardscrabble takes much inspiration from [[WesternAnimation/SleepingBeauty Maleficent]]. The artists even gave her Maleficent-style horns at one point in development, but ultimately decided that this was going too far.
* {{Foreshadowing}}: Her lecture to Sulley about scaring without thought serves as a reference to the scene in the first film when Sulley unintentionally scared Boo.
* GiantFlyer: Not humongous, but big enough to qualify.
* GoodIsNotNice: Hardscrabble has no respect for students she sees as "mediocre"... [[spoiler:but once you prove you're great, she'll be the first to tell you so]].
%%* IronLady
%%* JerkWithAHeartOfGold: [[spoiler:Eventually.]]
* JerkassHasAPoint: She and all other doubters are later proven undeniably right in [[spoiler: telling Mike he's not scary]]. In addition, when she dresses down Mike and Sulley, both fail her hypothetical scenarios, Mike for the above reasons, and Sulley because he doesn't use his head when scaring, implying both Mike and Sulley only sped up their inevitable failure in the school.
** She has fair reason to despise Mike and Sulley [[spoiler: for breaking her canister]] and notably aims her disdain directly toward them rather than the rest of Oozma Kappa.
** Her extremely demanding requirements for being a scaring major also make sense in-universe. Being a scarer, according to everything the monster world understands, is incredibly dangerous. You don't want incompetents going into what is treated as an extremely dangerous environment.
*** Not only dangerous for the scarers themselves, but, as she informs Sulley, a botched scaring expedition could literally lead to the ''end of civilization'' if the humans discover the Monster World.
* KickTheDog: Although she stays rather reasonable in her strictness, she's not immune to those moments and even gently taunts Mike after Oozma Kappa's near-loss in the first round. Granted, her grudge against him is understandable, but her flaw is that her criticisms are more unpleasant than helpful.
* LargeAndInCharge: Towers over most of the other monsters. She can appear even larger by opening her wings and using her centipede half to gain height.
* LivingLegend: She is the current holder of the All-Time Scare Record.
* MeaningfulName: "Hardscrabble" means "involving hard work or struggle." The Dean herself has no respect for monsters who are mediocre, lazy, or not using their talents to their fullest potential.
* MixAndMatchCritters: A centipede-dragon-humanoid hybrid.
* NonStandardCharacterDesign: Downplayed, but her darker colors and more striking design certainly stand out compared to the cartoony and colorful looking monsters making up Monsters University.
* NotSoStoic: She's the sternest, strictest, and most unflappable monster in the school. [[spoiler:But when Mike and Sulley create a scream of such power that it not only activates a door ''from the human side'', but '''fills up every scream canister in the laboratory until they and the door explode''', she goes into wide-eyed shock. Later, as she bids them good luck in their future endeavors, she informs that she believes in them because they did the one thing she thought was impossible: surprising her.]]
* ObviouslyEvil: Come on, she's basically a black and red centipede/dragon hybrid. [[spoiler: Subverted though.]]
* OurDragonsAreDifferent: She has some dragon-like qualities, at least, including her reptilian facial features, horns and batlike wings.
* PetTheDog: [[spoiler:While Mike and Sully are still expelled at the end, she lets the other Oozma Kappa members into the Scare Program after being impressed by how they did in the Games]].
* RetiredBadass: She retired from her Scarer life to become the School of Scaring's dean.
* SinkOrSwimMentor: If you can't take the heat, leave her school.
* SternTeacher: She's more harsh than actually cruel [[spoiler:and offers words of encouragement to Mike and Sulley as they leave MU]].
* ToughLove: This may be an interpretation of her behavior towards her students. As she says in her introductory scene, she doesn’t want to make her students "less mediocre", but as great as they can possibly be.
* TranquilFury: [[spoiler: When Mike and Sulley accidentally knock over and break her record making scare canister. Hardscrabble is surprisingly rather calm about it, stating it was fine as long as no one got hurt. Mike lampshades this... at least before she gives her impromptu tests to the two.]]
* WingedHumanoid: For a given definition of "humanoid".

----
%%* BigOlEyebrows
* CoolOldGuy: Just like Hardscrabble, he's a SternTeacher and RetiredBadass, after all.
* {{Expy}}: Looks like a small Uragaan from ''VideoGame/MonsterHunter''.
* FavouritismFlipFlop: {{Downplayed|Trope}}. He initially seems most impressed with Sulley's natural scaring talent, but when Sulley's [[BrilliantButLazy apathy towards studying]] causes his grades to suffer throughout the semester, Professor Knight gradually shifts his favoritism towards Mike instead. However, he sincerely congratulates Sulley for the improvement that he showed during the Scare Games, and says he looks forward to seeing him back in class.
-->'''Professor Knight:''' One frightening face does not a monster make, Mr. Sullivan.
* NonMammalianHair: His blunt spines on the top of his head resemble hair.
%%* ReasonableAuthorityFigure
* RetiredBadass: Not quite as much as Hardscrabble, but his Scare Card shown during the credits appears rather old in comparison to all the others, showing that he was a very successful Scarer before becoming a teacher.
* SternTeacher: He gives off a strong no-nonsense vibe at first, but he is genuinely very impressed over Mike's efforts and diligence.

[[folder:Professor William Brandywine]]
->'''Voiced by:''' Creator/GregDykstra
[[quoteright:182:https://static.tvtropes.org/pmwiki/pub/images/brandywine_7922.png]]

The teacher for Scream Can Design 101.
----
* BigOlEyebrows: So big, they cover his eyes.
* TheBore: Brandywine's lecture on scream can design is deadly dull from the word "go". His bored-sounding monotonous voice and his [[GoYeHeroesGoAndDie less than motivating]] words do not help this situation.
* CreepyMonotone: Not creepy per-se, just very droll and disinterested sounding.
* GagNose: His noise looks like it would be on a ''Series/SesameStreet'' character.
* GoYeHeroesGoAndDie: He's not exactly the best at motivating his students on the first day of class.
-->'''Brandywine''': Some say scream canister design is dull, a waste of a monster's potential. [''[[{{Beat}} conspicuously long pause]]''] Open your textbooks to Chapter 3.
* ReusedCharacterDesign: According to the official artbook, his character model is the same as Don Carlton's but with yellow fur.
* SpearCarrier: Is exclusive to one scene in the movie establishing what classes Mike and Sulley have been taking after being kicked out of the scare program.

%%* AttackOfTheFiftyFootWhatever
* BerserkButton: Don't make the ''slightest'' noise in the library when she's around.
* BlindWithoutEm: An example that's actually played realistically.
* ColdHam: She is very dramatic, and yet she never seems to raise the tone of her voice.
* DisproportionateRetribution: To anyone who makes a noise in her library, as shown when Bile steps on a creaky floorboard (which was completely out of his control). She quickly grabs him and throws him out the skylight, showcasing what the participants of the games were in for if they were caught.
* {{Expy}}: The Librarian's appearance and behavior takes inspiration from [[WesternAnimation/TheLittleMermaid1989 Ursula]].
* EyeOnAStalk: Her eyeballs are on stalks that give her a slug-like appearance.
* {{Hypocrite}}: Despite [[BerserkButton despising noise in her library]], the Librarian's rampages end up causing ''far'' more noise and disturbance than the offending monsters ever would.
* MixAndMatchCritters: She's a slug and octopus hybrid.
* MultiArmedAndDangerous: She has multiple tentacles to make her move around the library with ease and grab anyone who disrupts the peace.
* PowerEchoes: Her voice has a reverberating growl underscoring it that makes her even more menacing.
* ScaryLibrarian: Perhaps the ''scariest'' librarian around. She provides this tropes page image.
* TentacledTerror: The lower half of her body is a giant octopus, and she can be quite terrifying with her tentacles.
* TranquilFury: "I said '''QUIET'''."

* LaughOfLove: When Don [[AccidentalHug accidentally hugs]] Sheri and tries to get his tentacles unstuck, she giggles as she introduces herself, [[spoiler: and they eventually get married]].
* MoodKiller: When Oozma Kappa is trying to initiate Sulley and Mike into team by setting up a mysterious atmosphere in the darkness while dressed in dark cloaks, she interrupts the initiation by turning on the lights in the basement so she can use the washing machine.
* SingleWomanSeeksGoodMan: Sheri is engaged to [[spoiler: OK's TeamDad [[NiceGuy Don]]]].

* TheAce: Considered a superstar among Scarers.
* FriendToAllChildren: Frank is the only one of the Scarers at MI that actually stopped to talk to Mike's class when they were visiting. He even gives Mike his trademark MU cap as a gift.
* SmallRoleBigImpact: He only appears in the opening scene, but he leaves a huge impact on Mike and inspires him to pursue Scaring as a career. Mike's scaring style is greatly influenced by Frank's -- for example, the technique of waking a child up by ''slowly'' scratching your claws against the bedpost.
* TentacledTerror: He walks on long tentacles that act as his legs.

[[folder:Archie the Scare Pig]]
The mascot of Fear Tech (a rival school of Monsters University) that Sulley steals.

* HugeRiderTinyMount: Mike is a pretty small monster, yet it is amusing to see Mike ride around on a pig much smaller than him.
* {{Mascot}}: Of Fear Tech.
* MixAndMatchCritter: Being a monster, he is a furry pig-like creature with goat horns, six legs and [[HellishPupils goat pupils]].
* WhatHappenedToTheMouse: He is last seen when Sulley and Mike successfully catch him and claim him for Monsters University. After that, he is taken away by other monsters and never seen again after this point. It is unclear if Fear Tech ever got him back or not.

* AscendedExtra: While she only appeared in ''Monsters University'' as a non-speaking monster being observed by Oozma Kappa, ''Monsters at Work'' gives her a semi-prominent role as a student at Mike's scare school.
* FemmeFatalons: She is a female monster with long sharp retractable claws. They are pretty much [[WeaponForIntimidation for intimidation]] though, as she only uses them to look scary for her job.
* OlderThanTheyLook: Has been in Monsters, Inc for at least a decade or so before Mike and Sulley and her Scarer Card states she worked for Fear. Co in her first 4 years as a scarer, but when she appears ''Monsters at Work'', which is set about a decade after ''Monsters University'', she appears to have barely aged a bit.
* SuddenlyVoiced: She gains a voice in that series, too.
