History Main / EvilTeacher

* 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.

* 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.
* ''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]].

** 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.)

** Sarah is a 95-year-old Ceremonial Magician who attempts to cause trouble by throwing MC and Emily together in ways likely to cause Emily's father to want MC dead. [[spoiler:She then attempts to blackmail MC, gets her mind blown, and eventually becomes a necromancer.]]
** Torman is [[spoiler:Thor, Katie's grandfather. He tries to kill MC 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.]]

* ''VideoGame/{{Kindergarten}}'': 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.

** Denzel Q. Crocker slides from a simple pathetic SadistTeacher to truly evil depending on the episode. Compare the SympatheticPOV Crocker in "[[Recap/TheFairlyOddParentsS3E21TheSecretOriginOfDenzelCrocker The Secret Origin of Denzel Crocker!]]" to the maniacal dictator he becomes in the MadeForTVMovie episode ''WesternAnimation/AbraCatastrophe''.
