12-> "Hi there! I'm principal Nezu and I literally HATE HUMANS. You think that would be a conflict of interest but honestly, I'm no different from a majority of school staff. Now please, run in terror."
13-->-- [[WebVideo/XinXMinutes "My Hero Academia Season 2 in 8 minutes"]], Creator/TeamFourStar
14
15So you have a [[SadistTeacher cruel, mean bully of a teacher]], say the most banal sort of evil, that's got to make school life pretty harsh, right? Well, it could be worse, they could actually be evil on a much grander scale with much loftier plans.
16
17This includes {{Mooks}} and murderers whose day job is teaching, all the way up to {{Big Bad}}s who pose as teachers as part of the {{Masquerade}}. Not too uncommon in WakeUpGoToSchoolSaveTheWorld situations, but can also appear in other works which are set in a school or University.
18
19Sometimes this does overlap with the SadistTeacher, but it isn't too uncommon for [[HippieTeacher some iteration]] of [[MisplacedKindergartenTeacher supposedly "nice"]], [[SternTeacher and/or well liked, teacher]] to be secretly evil. Perhaps so secretly even [[TomatoInTheMirror they don't know]].
20
21If the Evil Teacher teaches in a WizardingSchool, chances are that he's likely an EvilSorcerer, a SorcerousOverlord, or a {{Necromancer}}.
22
23If they don't like teaching, a SadistTeacher can result. If they [[BecomingTheMask do like it]], they'll often end up a BadassTeacher. They may also be MoreThanJustATeacher. One rank up is the EvilPrincipal.
24
25Also not to be confused with the RuleOfTwo or the EvilMentor, who is not only evil, but also corrupts his disciples with evil teachings. Teachers found in an AcademyOfEvil are usually evil, but so are the students, so they don't count.

28!!Examples:
29[[foldercontrol]]
30[[folder:Anime and Manga]]
31* Kuzuki of ''VisualNovel/FateStayNight'' is a downplayed example. [[spoiler:He's well-liked among the students, and isn't actually evil. He's just amoral and has no problem going along with Caster's plans, which involve mass murder.]]
32* [[spoiler:Dante]] of ''Anime/FullmetalAlchemist2003''. [[spoiler:She's introduced as a kind old lady who was once Izumi's alchemy tutor, but it is eventually revealed that she is the BigBad behind the homunculi.]]
33* The StarterVillain of ''Anime/FutariWaPrettyCure'', Pisard, disguises himself as a student teacher named Ryuuichi Kazama in his day-to-day life. In episode 3, this disguise lets him slip into the Cures' middle school unnoticed and brainwash their actual teacher, Takenouchi, into taking them right into his clutches.
34* ''Manga/GreatTeacherOnizuka'' has several:
35** Suguru Teshigawara is a {{Yandere}} StalkerWithACrush on his fellow teacher Azusa, and eventually [[spoiler:kidnaps her]]. When Onizuka and Azusa's sister Makoto foil his plans, he goes off the deep end and [[spoiler:barricades himself inside the school with hostages and {{molotov cocktail}}s]].
36** CreepyGymCoach Hajime Fukuroda is mainly a HarmlessVillain, but he still has an unhealthy obsession with the teenage girls he teaches.
37** Tadashi Sakurai takes it one step further by being ThePeepingTom and recording photos and videos of schoolgirls in the bathrooms and locker rooms. He's been doing this for ''decades'', and yet [[KarmaHoudini he's never fired]], though at least some of the students use this to blackmail him.
38* Professor William James Moriarty of ''Manga/MoriartyThePatriot'' is actually a CoolTeacher who is [[BadassTeacher protective of his students]], but when he's not teaching or doing mathematics research, he's actively plotting or committing murders and views himself as the devil.
39* Harumi Saotome of the Higa team in ''Manga/ThePrinceOfTennis''. This is a guy who actually orders his pupils to ''throw balls at the rival coaches to injure them'', and throws tantrums when they don't go along with it.
40* ''Manga/GTOTheEarlyYears'': [[spoiler:Yoko "Nanno" Minamino]] is not only a SadistTeacher, he's also a [[PaedoHunt pedophile]]. His students use this information to blackmail him.
41* [[spoiler:Yuu Nikaidou-sensei]] of ''Manga/ShugoChara'', who is only a teacher as it involves screening children from Seiyo Academy to see if they possess the legendary "Embryo" as their "Hearts Egg". As the best way to draw out a "Hearts Egg" is to make a child become filled with self doubt about their aspirations for life and usually means that without outside help they get their dreams crushed, and he is a ChildHater, he's presented as evil.
42* The teacher in ''Manga/ASilentVoice'', who not only actively allows for a deaf student of his to be bullied and tormented constantly, he finds it fun to watch and even ''encourages'' it. When he and the class are in danger of being called out for this, he uses one of his students as a scapegoat, shifting all blame onto him. Said student spends the rest of the year facing ''worse'' torment than the deaf girl, and once again the teacher allows and encourages it readily.
43* SenseiChan Yuri Shibasawa in ''Manga/BoysAbyss'' is the protagonist Reiji's homeroom teacher who becomes a {{yandere}} after [[TeacherStudentRomance starting a sexual relationship with him]] and does everything in her power to keep him all to herself, from [[StalkerWithACrush stalking]] to trying to alienate him from his other loved ones. She even calls a parent-teacher conference to subtly tell his ''mother'' to back off. What makes it especially tragic is that she was a CoolTeacher with genuinely good intentions in the beginning but [[FaceHeelTurn her own fears and insecurities took over]].
44* ''Franchise/YuGiOh'':
45** In [[[Manga/YuGiOh the original manga]], it's hard to find a teacher in Domino High who ''isn't'' evil, or who at least isn't a creep. The worst is probably Ms. Chono (called "The Wicked Witch of Expel" by her co-workers behind her back for the sadistic way she punishes students), who is so bad that Yami actually inflicts a Penalty Game on her to teach her a lesson. (And compared to most of them, she actually gets off easy.)
46** ''Anime/YuGiOhGX'':
47*** Professor Viper, the BigBadWannabe of Season 3. He's a teacher at Duel Academy's west branch and presents his Disclosure Duels as a required academy course. His true motive is to use the Disclosure Duels to drain energy from the students and restore Yubel so they can revive his son.
48*** Mr. Stein has shades of being a WellIntentionedExtremist because he feels he has to eliminate Jaden, thinking that he, despite being a hero, is a bad influence on the other students. However, even with this in mind, Stein doesn't care at all that Viper is willing to let Alexis drown in order to help him win a duel. He fails to realize that he's little more than an UnwittingPawn for Viper, and it costs him in the end.
49*** Fonda Fontaine normally isn't an example, being one of the sweetest members of the faculty of Duel Academy. However, when much of the cast becomes [[BrainwashedAndCrazy Duel Zombies]] during Season 3, she's one of the most dangerous.
50%%*** Professor Crowler is much the same. (Administrivia/ZeroContextExample)
51** Henrietta Akaba from ''Anime/YuGiOhArcV'', the chairwoman of [[OpposingSportsTeam LDS]], is a morally dark-grey variant. She attempts to take over You Show by rather predatory means of pinning an incident on Yuya, but she intends to add his [[WrongContextMagic Pendulum Summoning]] to her school network to better combat [[AcademyOfEvil Academia]]. Even then, [[EducationMama there's the relationship]] [[WickedStepmother between her and Reira]]...
52%%** Mr. Kay from ''Anime/YuGiOhZexal'' really isn't any more evil than anyone else who is [[BrainwashedAndCrazy corrupted by a Number]] but he probably deserves notice. (What exactly does he do that's evil while he's corrupted?)
53[[/folder]]
54
55[[folder:Comic Books]]
56* In ''ComicBook/{{Invincible}}'', one of the first villains Mark fights is his Physics teacher, Mr. Hiles. Initially he doesn't seem so bad aside from him humiliating Mark and Eve for talking in class, but moments later it's revealed that he turned several of the popular boys at their high school into unwilling suicide bombers because he was bitter about kids ''like'' them [[DrivenToSuicide driving his son to suicide]]. He then tries to [[TakingYouWithMe blow the three of them up]], only for Mark to use his SuperSpeed to let him detonate over Antarctica.
57* ''ComicBook/SensationComics'': Don Enrago is hired as a fencing instructor at Holliday College, but unknown to everyone, he despises women and is disgusted at the idea of women being competent fighters. He uses his position to sabotage fencing gear prior to a competition in the hopes that his students and those they're fighting will be killed and captures one student with plans to torture her to death, though she is rescued in the nick of time by Franchise/WonderWoman.
58[[/folder]]
59
60[[folder:Fanfiction]]
61* ''Literature/HarryPotter'': ''Way'' too many authors like to portray Dumbledore as a ManipulativeBastard who's setting up Harry as a HeroicSacrifice to defeat [[BigBad Voldemort]], in some cases with Dumbledore planning to take all the glory immediately after. A few fanfics also have him paying off Ron/Hermione/Ginny/whoever to be Harry's "friend" as a way for Dumbledore to spy on him.
62[[/folder]]
63
64[[folder:Films -- Live-Action]]
65* Kitano in ''Film/BattleRoyale''. Although this is almost [[JustifiedTrope justified]] by the fact that the world has gone to hell and the students are unruly to the point of stabbing him at random in the hall. He doesn't actually do anything malevolent to them until after they've left school and he enrolls them in the BR program to force them to battle each other to the death.
66* In ''Film/TheFaculty'', the teachers are all gradually infected by {{Puppeteer Parasite}}s, before they move on to the student body.
67* In ''Film/HotFuzz'', [[spoiler:the schoolteacher is one of the members of the villainous NWA, who kill off anyone who makes the town look bad]].
68* ''Film/ThePeanutButterSolution'' has the Signor, an evil art teacher who kidnaps a student to make paintbrushes out of his magical hair. Yeah, it's that kind of film.
69* The BigBad of ''Film/PromNight2008'' was originally a teacher who took a sexual interest in one of his students. Three years after being incarcerated for murdering said student's family, he escapes and starts carving through her classmates to get to her at the senior prom.
70* All the movies in ''Film/TheSubstitute'' series will usually reveal that one of the other teachers (except for the first film, in which it's [[EvilPrincipal the principal]]) is actually controlling the criminal operation that the ActionHero teacher needs to dismantle.
71%%* The Assistant Principal, and the super-teachers he hires, in Korean action-comedy ''Volcano High''. (Administrivia/ZeroContextExample)
72* One member of the biker gang that threatens the protagonists' dream girls in ''Film/WeirdScience'' indicates that he is this as the bikers are retreating from Wyatt's house:
73-->'''Biker:''' Could we keep this between us? I'd really hate to lose my teaching job.
74* Terence Fletcher from ''Film/{{Whiplash}}'' is a more realistic example. Fletcher's goal is to train the next great jazz musician, but he will stoop to any low to achieve that goal. Even if it includes lying, harsh language, intimidation, or even physical violence.
75* Sam Lombardo in ''Film/WildThings'' is a guidance counselor at a prestigious Florida high school who rapes one of his students when he gets the chance. [[spoiler:Before it's revealed that he's a different kind of bad, as they were working together to con the girl's rich mom out of millions of dollars. Sam just seems to be a lying sleazeball... but at the end we learn that he's been sleeping with Kelly for a long time, thereby committing ''statutory'' rape.]]
76[[/folder]]
77
78[[folder:Literature]]
79* PlayedWith in ''Literature/{{Animorphs}}'' -- Vice Principal Chapman is a high-ranking Controller whose [[PuppeteerParasite Yeerk]], Iniss Two-Two-Six, is a recurring foe, especially in the early books; however, the real Chapman is generally characterized by being a PapaWolf who gave himself to the Yeerks to spare his daughter. (Then again, a prequel book shows that someone with his surname, presumably supposed to be him, [[TheQuisling willingly sold out the Earth to the Yeerks]] as a teenager ForTheEvulz, though that seems so out of character that [[FanonDiscontinuity some fans try ignore it]].)
80* Vice Principal Nero from ''[[Literature/ASeriesOfUnfortunateEvents The Austere Academy]]'' is a true sadist. He makes Sunny, a ''baby'', work as his secretary and punishes people by taking away silverware and tying people's hands behind their backs during lunchtime.
81%%** Coach Genghis -- who is really Count Olaf in a PaperThinDisguise -- from the same book. (Administrivia/ZeroContextExample; how is he evil?)
82* Kinpatsu Sakamochi from ''Literature/BattleRoyale'' is the FauxAffablyEvil bastard who oversees [[DeadlyGame the Program]]. He fancies himself the class's new teacher, a role he gained after [[KlingonPromotion having their previous teacher killed]], and will gladly have his students killed for such [[SarcasmMode heinous infractions]] as [[DisproportionateRetribution whispering while he's talking]]. In his first scene in the book, Sakamochi goads a student into a blind rage by claiming that he [[RapeIsASpecialKindOfEvil raped the woman who took care of him when he was an orphan]], and then uses the boy's fury as an excuse to [[BoomHeadshot shoot him in the head]].
83* ''Literature/BloodFever'' has [[spoiler:Professor Peter Haight]], who appears to be a ReasonableAuthorityFigure but is actually a member of a secret society dedicated to restoring UsefulNotes/TheRomanEmpire and who poisons the teenaged Literature/JamesBond when he gets too close to the truth.
84%%* Brother Leon in ''Literature/TheChocolateWar''. (Administrivia/ZeroContextExample)
85* ''Literature/DevinAndTheTeacher'' has the narrator insisting all teachers are evil.
86* ''Literature/HarryPotter'': Given that it's set in a WizardingSchool this isn't surprising.
87** The Defense Against the Dark Arts teacher often turns out to be this on account of the position being [[HighTurnoverRate cursed]]:
88*** [[spoiler:Quirrell is TheMole for [[BigBad Lord Voldemort]] and acts as a host to his spirit, trying to locate the Philosopher's Stone and kill Harry under the latter's instruction.]]
89*** [[spoiler:Lockhart isn't working for the villains, but the degree of selfishness it takes to steal others' memories for fame and be willing to let an eleven-year-old die to maintain his reputation probably counts as a banal kind of evil.]]
90*** [[spoiler:"Moody" is actually the Death Eater Barty Crouch Jr. in disguise, and is manipulating things for the sake of his plan to fully resurrect Lord Voldemort.]]
91*** Umbridge, former trope namer for TyrantTakesTheHelm, is a government stooge and FantasticRacist whose idea of detention involves students magically carving words into their own hands by writing lines and who forcibly removes every staff member who disagrees with her politics.
92*** [[spoiler:The Carrows were installed by Voldemort and aren't so much teachers as anti-Muggle propagandists. They're less subtle in their prejudice than Umbridge, and even more sadistic. Umbridge tortured students herself, while they encourage their favourites to torture other students.]]
93** Snape [[spoiler:is presented as an Evil Teacher but proves not to be. He's actually a DoubleAgent who spies on Voldemort on behalf of Dumbledore. He's still a SadistTeacher though.]]
94* In ''[[Recap/WarriorCatsIntoTheWild Into the Wild]]'', Tigerclaw -- Ravenpaw's mentor, and partial mentor to Firepaw before Bluestar -- is a VillainWithGoodPublicity: He secretly murdered the Clan deputy in the hope of being chosen for the role, and intends to continue killing his way to leadership. He even tries to kill his apprentice Ravenpaw (who [[HeKnowsTooMuch witnessed the murder]]) by assigning him dangerous tasks (hunting in enemy territory, or at the rocks where poisonous snakes live).
95* Agatha Trunchbull in ''Literature/{{Matilda}}'' isn't just a SadistTeacher, it becomes obvious at the end that [[spoiler:she probably either herself murdered Miss Honey's father/her brother-in-law or at least had him assassinated]].
96* In the picture book ''My Teacher is a Monster!'', a young boy named Bobby thinks that his teacher is one of these and visualizes her as a giant green-scaled monster. However, when he gets to know her better, he slowly realizes that she's really just a SternTeacher who can be friendly with him and her appearance gets progressively less monstrous until she's completely human-looking at book's end... well, except for when Bobby misbehaves in class.
97* In ''[[Literature/AlexRider Point Blanc]]'', the eponymous Point Blanc is an exclusive boarding school for the troubled sons of wealthy families. There are only two teachers: MadDoctor Dr. Hugo Grief and [[TheDragon his Dragon]], the freakishly strong Mrs. Stellenbosch. Aside from being unrepentant white supremacists, [[spoiler:Grief is secretly replacing the boys under his care with clones of himself to allow them to control the world in a generation]].
98%%* ''[[Literature/DiamondBrothers Public Enemy Number Two]]'' has [[spoiler:SadistTeacher Mr. Palis turn out to have been "The Fence" all along]]. (Administrivia/ZeroContextExample; how exactly is "The Fence" evil?)
99* ''Literature/{{Salamander}}'' features [[EvilSorcerer Maridon]], one of the teachers in the story's College of Magic. He's not presented as a bad teacher, just as a teacher who wants to be a PersonOfMassDestruction.
100* The criminal mastermind Professor James Moriarty from ''Literature/SherlockHolmes'' was a mathematics professor until dark rumors forced him to resign. The nature of these rumors and how true they were is unknown, but presumably, they were not pleasant and not entirely inaccurate.
101* Creator/MichaelRosen's story "Strict" is about a teacher so strict, students aren't allowed to breathe in her lessons. Any student caught violating this rule gets sent to an underground prison where they are strung up from the wall bars for weeks while rats nibble on their toes.
102* ''The Teacher from the Black Lagoon'' and its many, many sequels would qualify as the best example if ''Series/TheXFiles'' hadn't taken that honor. "This is a whole boy. [[HalfTheManHeUsedToBe This is half a boy.]] Now you've learned fractions." [[spoiler: [[AllJustADream But they're always more or less in the main character's overactive imagination and the school staff are more or less pleasant people]] most of the time]].
103* Professor Denovo, the protagonist's former mentor in ''Literature/ThreePartsDead'', is a ''monster'' in ways that take most of the book for the reader to really appreciate. [[spoiler:He once [[MindRape stripped Tara of free will]], then tried to have her killed when she rebelled. He is a self-made HumanoidAbomination. And he has a ''completely plausible'' plan to make himself something rather greater than a god.]]
104* ''Literature/WaysideSchool'':
105** Mrs. [[SdrawkcabName Gorf]], who turns students into apples.
106** Mrs. Gorf's son, who steals the students' voices and uses them to call their parents and tell them they hate them.
107** Ms. Nogard, who uses her mind-reading ability to make the students miserable and turn them against one another.
108* Miss Gaunt in ''[[Literature/GhostsOfFearStreet Who's Been Sleeping in my Grave?]]''. She's good ''at'' teaching, it just so happens that she wants to pull students into the grave to teach them forever, which is where the evil part comes in. There's also the matter of [[spoiler:makin their usual teacher sick so she can take over the class]].
109%%* Madame Morrible from ''Wicked''. Both [[Theatre/{{Wicked}} the musical]] and [[Literature/{{Wicked}} the book]]. (Administrivia/ZeroContextExample)
110[[/folder]]
111
112[[folder:Live-Action TV]]
113%%* Parodied on ''Series/ANTFarm'' with Skidmore, as shown by the page quote.
114* ''Series/BuffyTheVampireSlayer'':
115** "[[Recap/BuffyTheVampireSlayerS1E4TeachersPet Teacher's Pet]]" has [[MonsterOfTheWeek "Ms. French"]], a praying mantis demon who seduces her male students to mate with them and bite their heads off. She's the one who starts Xander's streak of attracting demon women.
116** In season four, there's the KnightTemplar Psychology professor Maggie Walsh, head of the Initiative.
117* ''Series/ChoujuuSentaiLiveman'': Great Professor Bias preys on promising young university students and coerces them to join the [[AcademyOfEvil Volt]] with the promise of gaining more knowledge, all while coercing them to give up their humanities and become more cold-hearted.
118* ''Series/DoctorWho'': In "[[Recap/DoctorWhoS28E3SchoolReunion School Reunion]]", Deffry Vale School has the teachers (and kitchen staff, and nurse) [[EvilPrincipal new headmaster Mr. Finch]] brought with him. They're [[ToServeMan human-eating]] aliens who are both exploiting and killing the students in a plot to become gods.
119* ''Series/FamilyTies'': Mr. Tedesco from "[[Recap/FamilyTiesS2E3TheHarderTheyFall The Harder They Fall]]", thanks to his sadistic, insulting personality. Several students have complained to their parents about his abrasiveness and sometimes cruel behavior in the classroom, including the parent of a student he says is a "loser" and a "pimple-faced liar", while advising that another student and her mother need to lose weight. At one point, when family patriarch Steven is trying to get an explanation from Tedesco, he makes crude remarks about Elyse, who had earlier punched him out.
120* ''Series/TheFlash2014'' has The Thinker, aka Clifford [=DeVoe=], who is a former professor who becomes the BigBad of [[TheFlash/SeasonFour Season 4]].
121%%* All teachers in ''Series/HouseOfAnubis'' tend to fall into this trope: (Administrivia/ZeroContextExample; how are they evil, or ''appear'' evil in the case of the subverted examples?)
122%%** Victor.
123%%** Vera.
124%%** Miss Denby.
125%%** Subverted with Jason, who actually tries to ''help'' Patricia in the beginning and still cares about her well-being even after his FaceHeelTurn. Later it's revealed that [[spoiler:he only joined Victor and the others because he was suffering a degenerative illness and immortality was the only way to save his life]].
126%%** Another subversion is Mrs. Andrews, who [[spoiler:quits the society and leaves the school as she feels the students should come first]].
127* ''Series/{{Itch}}'': Dr. Flowerdew, who gets one of his students sent to hospital, and later kidnaps them.
128* PlayedForLaughs in the "Self-Defence Against Fresh Fruit" skit in the ''Series/MontyPythonsFlyingCircus'' episode "[[Recap/MontyPythonsFlyingCircusS1E4 Owl Stretching Time]]". The teacher teaches the students how to defend themselves against fresh fruits, more dangerous than pointed sticks[[labelnote:*]]SHUT UP[[/labelnote]] by telling them to attack him with fruits, and then he kills the students one by one in the name of "self-defense", in increasingly crazy ways (first shooting the student with a gun, then dropping a 1-ton anvil on another, then releasing a tiger to devour the rest).
129* Mr. Sweeny in ''Series/NedsDeclassifiedSchoolSurvivalGuide'', most notably in the teacher's episode where he's actually labeled as the evil teacher who wants nothing more than to see you fail. Subverted later on, though, when Ned comes to the conclusion that no teachers are evil, and they just want to see you succeed. Along with this, Mr. Sweeny shows moments where he is actually a nice guy, just strict.
130* In the ''Series/TheOuterLimits1963'' episode "[[Recap/TheOuterLimits1963S1E28TheSpecialOne The Special One]]", Mr. Zeno, an alien in human form, tutors gifted children, planning to indoctrinate them and use their advanced scientific skills to help his planet conquer Earth. Zeno kills one father who discovers what's going on, and [[spoiler:almost kills another before his current pupil (the son of Zeno's intended target) turns the tables on him]].
131* In ''Series/TheSarahJaneAdventures'' story "[[Recap/TheSarahJaneAdventuresS1E1E2RevengeOfTheSlitheen Revenge of the Slitheen]]", the Slitheen pose as teachers worldwide during their revenge plot.
132* In ''Series/{{Smallville}}'', [[RoboticPsychopath Brainiac]] mixes this with BadassBookworm, EvilMentor, and OmnicidalManiac. No, he's not your average History Prof.
133* Mrs. Argent and Kate Argent from ''Series/TeenWolf''. Both are part of a hunter family that is out to kill most of the main characters. Kate even burned down a house that contained all of Derek's family members, and Mrs. Argent blatantly threatens Scott with death if he continues to date her daughter.
134%%* He's only briefly a teacher, but Cromartie from ''Series/TerminatorTheSarahConnorChronicles''.
135* Alaric Saltzman becomes this at the end of the third season of ''Series/TheVampireDiaries'', complete with torturing one of his vampire students in his classroom.
136* Ms. Paddock from the ''Series/TheXFiles'' episode "[[Recap/TheXFilesS02E14DieHandDieVerletzt Die Hand Die Verletzt]]". [[spoiler:She is actually a manifestation of the demon Azazel.]]
137[[/folder]]
138
139[[folder:Music]]
140* An evil teacher is featured in the music video for [[Music/TwistedSister Twisted Sister's]] "I Wanna Rock". The teacher is seen giving his student's three hours of detention in the basement and trying to murder Twisted Sister with [[HoistByHisOwnPetard explosives]].
141[[/folder]]
142
143%%[[folder:TabletopGames]]
144%%* Every teacher in ''Miskatonic School for Girls''. It's pretty much the point of the game. (Administrivia/ZeroContextExample)
145%%[[/folder]]
146
147[[folder:Video Games]]
148* Baldi from ''VideoGame/BaldisBasicsInEducationAndLearning'' is a teacher who seems innocuous at first. He forces you to solve math problems to progress through the game, but if you get even a single question wrong, Baldi ''will'' kill you. To make things worse, some of the problems are [[FailureIsTheOnlyOption unsolvable on purpose]], so you are ''forced'' to make him come after you.
149* ''VideoGame/{{Kindergarten|2017}}'': Mrs. Applegate will give you gold stars for expelling students from her class, usually by violent and/or fatal means. She also wants to start a kiddie fighting ring.
150* In ''VideoGame/LifeIsStrange'', [[spoiler:Mark Jefferson seems to be a nice guy at first, but turns out to be the BigBad by the end]].
151* ''VideoGame/LittleNightmaresII'' has, well, the Teacher. She's a MonstrousHumanoid who can [[LongNeck stretch her neck to extreme limits]]. She is implied to be abusive towards her students both within the game itself and in promotional material, and she will attempt to catch and kill Mono if she finds him wandering throughout her school.
152* ''VideoGame/LoveOfMagic'':
153** Sarah is a 95-year-old Ceremonial Magician who attempts to cause trouble by throwing Owyn and Emily together in ways likely to cause Emily's father to want Owyn dead. [[spoiler:She then attempts to blackmail Owyn, gets her mind blown, and eventually becomes a necromancer.]]
154** Torman is [[spoiler:Thor, Katie's grandfather. He tries to kill Owyn in an attempt to cripple the Courts in order to make them a more tempting target for the Outsiders. He got the job by ambushing Booker, the actual Evoker professor.]]
155* ''VideoGame/{{Misao}}'': [[spoiler:Mr. Kurata, the teacher of Aki's class, turns out to be a member of the BigBadEnsemble, having killed Misao herself for rebutting his advances, then Ayaka once [[HeKnowsTooMuch she put two and two together]], and in the bad ending, he kills Aki after they find out as well. [[FreudianExcuse In his defense]], [[DarkAndTroubledPast he was brutally mistreated in his youth]] and led to believe that nobody cared about his genuine efforts to try and be a good person]].
156* The first main antagonist you encounter in ''VideoGame/Persona5'' is Suguru Kamoshida, a PE teacher and the volleyball team coach at your school. He has been physically abusing his male team members and sexually harassing female team members; it's even implied that he raped one of his students, resulting in the latter attempting suicide. He has gotten away with all of these simply because he was a former Olympic medalist, and everyone who knows his atrocious acts are either too scared to tell or are turning a blind eye due to his past achievement.
157* In [[https://www.youtube.com/watch?v=MJnHkRgDnpc one trailer]] for ''VideoGame/WildStar'', the android teacher is rather cruel in her vivid descriptions of the brutal, gory deaths her students will likely suffer on Nexus, but then offers them an alternative (as in, a MercyKill).
158[[/folder]]
159
160[[folder:Visual Novels]]
161* In ''VisualNovel/ChaosChild'', it is revealed both in [[spoiler:Hana's]] and [[spoiler:Serika's]] routes that [[spoiler:Shuuichi Wakui]] is a ruthless assassin for the Committee of 300 that has no problem killing or torturing whoever gets in their way.
162* In ''VisualNovel/PhoenixWrightAceAttorneyDualDestinies'': Professor Aristotle Means is a seemingly friendly law teacher that teaches his students that "The ends justify the means", and that a defense lawyer should use any methods necessary to win a court case. [[spoiler:It turns out that he's taking bribes, and murdered another teacher when she found out, trying to get one of his students convicted in his place.]]
163[[/folder]]
164
165[[folder:Webcomics]]
166* ''Webcomic/{{Aisopos}}'': The teacher in Agoge. He beats up Lenius just because he was late, threatens him to cut one of Aesop's limps and then, Daross to bring him back, or else he will kill his brother.
167* ''Webcomic/AngelMoxie'' has [[spoiler:the MisplacedKindergartenTeacher Mrs. Merriweather, who turns out to be a demonic underling of the villains]].
168* ''Webcomic/DICETheCubeThatChangesEverything'': Teacher [[spoiler:Kim Youngsuk]] accidentally becomes a Dicer after picking a Dice [[spoiler:from dead Sungchul]], and argues with X that adults are forgetting what fun is. He joins the War Quest on the Attack's side, commenting he'd hate a boring life and [[spoiler:nearly kills the targeted teacher Chun Sobong, who's confirmed to pass away later]].
169* As shown in the page image above, ''Webcomic/ThePerryBibleFellowship'' has Mr. Rex, a tyrannosaurus rex who serves as a teacher for a school of dinosaurs.

174* Most of the teachers at ''WesternAnimation/BromwellHigh'' are just {{apathetic|teacher}} and/or dumb as a sack of bricks, but then we have Roger Bibby the deputy head/geography teacher. He is insatiably greedy and selfish, devoted to making money by any means necessary, abusive, manipulative, is on a first-name basis with demons, and has links to both the slave trade and diamond smuggling in Angola. Ironically, in spite of being easily the evilest teacher at the school, he's also probably the ''best'' teacher at the school because he's at least well-spoken, articulate, and actually knowledgeable.
175* Subverted by Mrs. Thomson the [[OurWerebeastsAreDifferent Were-Dog Queen]] from ''WesternAnimation/CodenameKidsNextDoor''. [[spoiler:She was [[NotEvilJustMisunderstood inflicted by the curse of lycanthropy by an angry ex-husband]], and turns out to actually be a rather decent sort in the end.]]
176* ''WesternAnimation/CourageTheCowardlyDog'': "[[Recap/CourageTheCowardlyDogS4E52RemembranceOfCouragePastPerfect Perfect]]" has a mysterious old teacher who approaches Courage and strictly trains him into becoming a perfect dog.
177* ''WesternAnimation/TheFairlyOddParents'':
178** Denzel Q. Crocker is a pathetic SadistTeacher by profession, but wants to prove the existence of magic and harness it to TakeOverTheWorld, and has more than once expressed a willingness to kill people in the process. When he does get his hands on magic power in the MadeForTVMovie episode ''WesternAnimation/AbraCatastrophe'', he becomes a maniacal dictator.
179** The episode "[[Recap/TheFairlyOddParentsS5E34NoSubstituteForCrazy No Substitute for Crazy]]" features a new seemingly friendly substitute teacher; however, after Timmy wishes for her to become his permanent teacher, the CoolTeacher façade drops and she is revealed to be a more ruthless and cruel fairy hunter than Crocker, torturing her students until she finds out which one has fairies.
180%%* Mr. Mufflin from ''WesternAnimation/FanBoyAndChumChum'', who is also the show's BigBad.
181%%* ''WesternAnimation/InvaderZim'' had Miss Bitters.
182%%* Miss [=MacBeth=] from ''WesternAnimation/InvisibleNetworkOfKids''.
183* ''WesternAnimation/PennZeroPartTimeHero'': The BigBad Rippen works as the art teacher at the heroes' school when not working as a part-time villain. Although, for what it's worth, he keeps his evil out of the school, being an ApatheticTeacher who is only there to pay the bills. His minion Larry is the school principal, although [[MinionwithAnFInEvil there's barely if anything evil about him at all]].
184* The fill-in for Ms. Keane in ''WesternAnimation/ThePowerpuffGirls1998'' episode "[[Recap/ThePowerpuffGirlsS5EP6SaveMojoSubstituteCreature Substitute Creature]]" subverts this. The girls assume that he's mean and villainous because he's, well, monstrous looking. But his credentials as a qualified teacher show the girls otherwise.
185* ''WesternAnimation/TheSimpsons'': In "Nightmare Cafeteria", the third segment of "[[Recap/TheSimpsonsS6E6TreehouseOfHorrorV Treehouse of Horror V]]", the faculty of Springfield Elementary become cannibals to solve the overcrowding of students in detention and food budget cuts. The only exception is Groundskeepr Willie, but he takes an axe to the back before he can rescue the kids from Skinner.
186* Mother Goose from ''WesternAnimation/TeenageFairytaleDropouts'' bullies the main trio after they push her BerserkButton.
