[[caption-width-right:348:This won't end well...]]

->''"Thanks for accepting my request for help after I only asked once, Lexi. Normally, it takes at least two requests, and some kind of message, like a finger in a box."''
-->-- '''Principal Skidmore''', ''Series/ANTFarm''

So you have a [[SadistTeacher cruel, mean, bully of a teacher]], that's got to make school life pretty harsh right? Well it could be worse, they could actually be ''evil''.

This includes {{Mooks}} and Murderers whose day job is teaching, all 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.

Sometimes 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]].

If they don't like teaching, a SadistTeacher can result. If they [[BecomingTheMask do like it]], they'll often end up a BadassTeacher.

Also 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.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* Harumi Saotome of the Higa team in ''Manga/ThePrinceOfTennis''. This is the guy who actually orders his pupils ''throw balls at the rival coaches to injure them'', and throws tantrums when they don't go along with it.
* Kuzuki of ''FateStayNight'' is a bit of a subversion. [[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.]]
* ''Franchise/YuGiOh'':
** In the original manga, it was hard to find a teacher in Domino High who ''wasn't'' evil, or who at least wasn't a creep. The worst was probably Ms. Chono (called "The Wicked Witch of Expel" by her co-workers behind her back for the sadistic way she punished students) who was so bad that Yami actually inflicted a Penalty Game on her to teach her a lesson. (And compared to most of them, she actually got off easy.)
** Professor Cobra, the BigBadWannabe of Season 3 of ''Anime/YuGiOhGX''.
** Calling Napolean (also from ''GX'') evil may be a stretch; he was certainly a {{Jerkass}}, but he did have some good points. Eventually, he made a complete HeelFaceTurn.
** Professor Chronos was much the same.
** Then there was Professor Satou. He probably could be considered a WellIntentionedExtremist because he felt he had to eliminate Judai, thinking that Judai (who was a hero despite being a poor student) was a bad influence on the other student. (He failed to realize that he was little more than an UnwittingPawn for Cobra, and it cost him in the end.)
*** He didn't care at all that Cobra was willing to let Asuka drown in order to help him win the duel. ''Definitely'' evil.
** Ayukawa wasn't evil in the least; she was one of the sweetest members of the faculty of Duel Academy. However, when much of the cast became [[BrainwashedAndCrazy Duel Zombies]] during Season 3, she was one of the most dangerous, and probably should be mentioned.
** There was also Professor Ukyo from ''Anime/YuGiOhZexal''. He really wasn't any more evil than anyone else who was [[BrainwashedAndCrazy corrupted by a Number]] but he probably deserves notice.
* [[spoiler: Dante]] of the [[Anime/FullmetalAlchemist 2003 anime version]] of ''Manga/FullmetalAlchemist''. [[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.]]
* [[spoiler:Yuu Nikaidou-sensei]] of ''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.
* The teacher in ''Manga/KoeNoKatachi'', who not only actively allows for a deaf student of his to be bullied and tormented constantly, 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 then the deaf girl and once again the teacher allows and encourages it readily.
[[/folder]]

[[folder:Film]]
* In ''Film/TheFaculty'', the teacher are all gradually infected by {{Puppeteer Parasite}}s, before they move on to the student body.
* 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
* Sam Lombardo in ''Film/WildThings'', 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.]]
* The Assistant Principal, and the super-teachers he hires, in Korean action-comedy ''VolcanoHigh''.
* In ''Film/HotFuzz'', [[spoiler: the schoolteacher is one of the members of the villainous NWA.]]
* One of the biker gang in ''Film/WeirdScience'' indicates he is this as the bikers are retreating from Wyatt's house:
-->'''Biker:''' Could we keep this between us? I'd really hate to lose my teaching job.
* All the movies in ''Film/TheSubstitute'' series will usually reveal that one of the other teachers is actually controlling the criminal operation that the ActionHero teacher needs to dismantle.
[[/folder]]

[[folder:Fan Fiction]]
* ''Literature/HarryPotter'' fanfiction. ''Way'' too many people 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.
[[/folder]]

[[folder:Literature]]
* ''TheDemonHeadmaster'' kinda [[RoleCalled evident from the title]].
* ''Literature/HarryPotter'': given that it's set in a WizardingSchool this isn't suprising. Most of the books had one, usually the [[HighTurnoverRate Defense Against the Dark Arts]] teacher. [[spoiler:Snape is presented as an Evil Teacher but proves not to be.]]
** ''Literature/HarryPotterAndThePhilosophersStone'' - [[spoiler:Quirrell, though he was TheMole so he didn't act harshly to the students.]]
** ''Literature/HarryPotterAndTheChamberOfSecrets'' - [[spoiler: Lockhart wasn'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.]]
** ''Literature/HarryPotterAndThePrisonerOfAzkaban'' - none [[spoiler: [[BadassTeacher Lupin]] certainly wasn't evil...well maybe for [[OurWerewolvesAreDifferent one night]] every few months if he didn't get his wolfsbane potion...]]
** ''Literature/HarryPotterAndTheGobletOfFire'' - [[spoiler:Moody (though he's NotHimself, but Barty Crouch Jr. in disguise), and Igor Karkaroff as Ex-Death Eater turned coward Headmaster]]
** ''Literature/HarryPotterAndTheOrderOfThePhoenix'' - Umbridge, former trope namer for TyrantTakesTheHelm, whose idea of detention involves students magically carving words into their own hands by writing lines.
** ''Literature/HarryPotterAndTheDeathlyHallows'' - [[spoiler: The Carrows, who 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.]]
* 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.]]
* Coach Gengis - who is really Count Olaf in disguise - from ''ASeriesOfUnfortunateEvents''. (Not spoilered because... well, it's [[PaperThinDisguise Count Olaf we're talking about]]).
** Vice Principal Nero from the same book in the series is a true sadist. He makes Sunny (A BABY) work as his secretary, punishes people by [[FetishFuel taking away silverware and tying people's hands behind their backs during lunchtime.]]
* ''Literature/TheGuardiansOfTimeTrilogy'' tries to do this and fails miserably.
* As does The German ''Literature/HarryPotter[=/=]Literature/TheNeverendingStory[=/=]Literature/TheLordOfTheRings'' knock-off ''TheLauraCycle''
* On of the Literature/DiamondBrothers novel ''Public Enemy Number Two'' has [[spoiler:SadistTeacher Mr. Palis turn out to have been "The Fence" all along]]
* Madame Morrible from ''Wicked''. Both [[Theatre/{{Wicked}} the musical]] and [[Literature/{{Wicked}} the book]].
* Miss Gaunt in ''Ghosts of Literature/FearStreet: Who's Been Sleeping in my Grave?''.
* ''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."
* Mrs. [[SdrawkcabName Gorf]] in the ''WaysideSchool'' series, who turned students into apples. There were several other evil teachers as well.
* Vice-Principal Chapman from ''Literature/{{Animorphs}}'', who's high up in the [[PuppeteerParasite Yeerk]] front organization The Sharing (which is similar to a scouting group or something) and often tries to recruit students, including the protagonists. He ''acts'' like a nice guy, though.
* ''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.
* [[Literature/SherlockHolmes Professor James Moriarty]].
* The ''YoungBond'' novel ''Blood Fever'' has [[spoiler: Professor Peter Haight]], who appears to be a ReasonableAuthorityFigure but it as actually a member of a secret society dedicated to restoring the Roman Empire and who poisons the teenaged Literature/JamesBond when he gets to close to the truth.
* Brother Leon in ''Literature/TheChocolateWar''.
* ''Literature/DevinAndTheTeacher'' has the narrator insisting all teachers are evil.
* 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.]]
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/PowerRangersDinoThunder'' - Principal Randall, aka [[spoiler:aka Elsa, TheDragon to BigBad Mesogog. While Mesogog's human alter ego, Dr. Anton Mercer, also stood in as a teacher for a while, he doesn't count as Mercer was good and resisting Mesogog's control.]]
* Half the faculty (including a few dinner ladies) in the ''Series/DoctorWho'' episode "School Reunion".
* ''Series/TheSarahJaneAdventures'' story ''Revenge of the Slitheen''.
* ''Series/BuffyTheVampireSlayer'' - "Teachers Pet"
** In season four of Buffy, there was the KnightTemplar Psychology professor Maggie Walsh.
* Ms. Paddock from the second season ''[[Series/TheXFiles X-Files]]'' episode "Die Hand Die Verletzt". [[spoiler: She actually is a manifestation of demon Azazel.]]
* He's only briefly a teacher, but Cromartie from ''TheSarahConnorChronicles''
* In the ''OuterLimits'' episode "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]].
* In ''{{Smallville}}'' [[RoboticPsychopath Brainiac]] mixes this with BadassBookworm, EvilMentor, and OmnicidalManiac. No he's not your average History Prof.
* The headmaster Mr. Finch and the new staff he installed in the Deffry Vale School in the ''Series/DoctorWho'' episode "School Reunion".
* PlayedForLaughs in ''Series/MontyPythonsFlyingCircus'' skit "Self-Defense Against Fresh Fruits". 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 killed the students one by one in the name of "self-defense", in an 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).
* Mr. Sweeny in ''Series/{{Neds Declassified School Survival Guide}}'', most notably in the teacher's episode where he was 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.
* All teachers in ''Series/HouseOfAnubis'' tend to fall into this trope, most notably Victor, Vera and Miss Denby.
** Also tends to be subverted, as this is mostly just a title, and many of the teachers still do genuinely care for the students despite being part of the 'evil' group, most notably Jason, who had actually tried to HELP Patricia in the beginning and still cared about her well-being even after his [[FaceHeelTurn FaceHeelTurn]]. Later it was revealed that [[spoiler:he had only joined Victor and the others because he was suffering a degenerative illness and immortality was the only way to save his life.]] Other examples of this are Mrs. Andrews, who [[spoiler:quits the society and leaves the school as she feels the students should come first]] and Mr. Sweet, who despite almost always taking Victor's side, [[spoiler:is Eddie's father]] and whenever the students are in trouble, chooses them over Victor. He also left the society in the second season to focus on being a good principle.
* Parodied on ''ANTFarm'' with Skidmore, as shown by the page quote.
* Alaric Saltzman becomes this at the end of the third season of ''TheVampireDiaries'', complete with torturing one of his vampire students in his classroom.
* ''Series/TheDoctorBlakeMysteries'': When Blake and Lawson investigate a murder at their old school, the discover the deputy headmaster is a SchoolyardBullyAllGrownUp who still enjoys tormenting those weaker than himself.
* Mrs. Argent and Kate argent from ''Series/TeenWolf'': Both part of a hunter family that is out to kill most of the main characters and Kate even did burn down a house that contained all of Derek's family members and Mrs. Argent blatantly threating Scott with death if he continues to date her daughter.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/AngelMoxie'' has an evil teacher, it's [[spoiler:the MisplacedKindergartenTeacher Mrs. Merriweather]] also [[spoiler:Mrs. Konk is a robot, she's not evil though just a SadistTeacher]]
* ''Webcomic/TheWotch'' has [[spoiler:Ms. Dahlet, the leader of the [[StrawFeminist Militant Feminist Group]] D.O.L.L.Y.]]
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/AaahhRealMonsters'' had The Gromble.
* ''WesternAnimation/CourageTheCowardlyDog'': Episode 52 Part 2: "Perfect" had a mysterious old teacher approaches him, and strictly trains him into becoming a perfect dog.
* Denzel Q. Crocker from ''WesternAnimation/TheFairlyOddparents'' slides from a simple pathetic SadistTeacher to truly evil depending on the episode. Compare the SympatheticPOV Crocker in "The Secret Origin of Denzel Crocker!" to the maniacal dictator he becomes in the MadeForTVMovie episode ''Abra-Catastrophe!''.
** Ms. Sunshine AKA Ms. Doombringer is even worse.
* Headmistress from ''WesternAnimation/MuchaLucha''. (Well, most of the time. She does have a softer side that she occasionally shows.)
* ''WesternAnimation/InvaderZim'' had Miss Bitters.
* ''XMenEvolution'' has Bayville High's Principal Darkholme [[spoiler:that is, Raven Darkholme, a.k.a. Mystique]]. Kelly was no slouch, either, especially after mutants were exposed.
* Miss [=MacBeth=] from ''InvisibleNetworkOfKids''.
* Mr. Wilter from ''WesternAnimation/ChalkZone''.
* Mary Gibbons from ''WesternAnimation/TheMightyB''.
* While you would have expected this type of villain to have been common in ''WesternAnimation/CodenameKidsNextDoor'' (the heroes fought evil adults, after all), the team tended to have bigger problems with evil ''students'' than with teachers. In fact, the closest they ever came to a villain like this was Mrs. Thomson, the [[OurWerebeastsAreDifferent Were-Dog Queen]], and [[spoiler: [[NotEvilJustMisunderstood she was a subversion]], having been inflicted by the curse of lycanthropy by an angry ex-husband. She turned out to actually be a rather decent sort in the end.]]
* Rancid Rabbit and Sally O'Neil from the ''WesternAnimation/CatDog'' episode, Back to School.
* Mr. Mufflin from ''WesternAnimation/FanBoyAndChumChum'' who is also the show's BigBad.
* The fill-in for Ms. Keane in ''ThePowerpuffGirls'' episode "Substitute Creature" subverts this. The girls assume he's mean and villainous because he's, well, monstrous looking. But his credentials as a qualified teacher show the girls otherwise.
