Badass Teacher

Go To
I wish we were learning that instead of marine biology.
Abraham: Feigned frailty, no "En garde"... Have you no honor?
Raven: The lives of my students are more important. Besides which, I did warn you.

Sometimes, you have a teacher who is not a sadist, particularly strict, or overly nice. They are just a regular teacher. Maybe. Until you threaten their students. After that you might want to start praying to whatever god is out there for mercy. You do not mess with their students. Getting away with just a lecture is not an option. Detention, even less. And don't even think about getting off with a warning. These are the teachers that make you wish they'd leave discipline up to the principal.

A Sadist Teacher wants their students to suffer. A Badass Teacher wants those who make their students suffer to suffer. It is not uncommon for the same person to be both ("You can't do that to my student; only I can do that to my student!"), but if the Badass Teacher and the Sadist Teacher are different people, expect the two to have at least one confrontation over the treatment of their students.

Usually they're the Non-Action Guy (or Girl) type, or a nerd. Often they're well-respected and popular with their students (though this isn't always the case). This is also common with Evil Teachers who actually like their day job. Anyone who runs a martial arts school is almost certainly also this trope, since their entire day job is teaching students how to fight anyway.

If a Hippie Teacher or a Misplaced Kindergarten Teacher is prone to this, running away as fast as possible is probably a good idea. If the school in question is run by a church, it might overlap with Badass Preacher.

Usually not Truth in Television, as any real teacher who behaved this way would in most cases lose their job and become a Fired Teacher — but see the Real Life examples below.

For the parenting equivalents, see Mama Bear and Papa Wolf. For an older sibling who acts like this, see Knight Templar Big Brother. Can overlap with Beware the Nice Ones, and occasionally Badass Normal in worlds with Supers. For a similar character, see Badass Bureaucrat. Contrast Sadist Teacher.

    Anime & Manga 
  • Assassination Classroom features Koro-sensei, a nonhuman teacher badass enough to destroy most of the moon, turning it into a permanent crescent, capable of moving at Mach 20, temporarily cloning himself to teach his students individually at once, and immune to all weaponry besides a specific form of Applied Phlebotinum. And his almost as badass class. Who are tasked with killing him. Because if they don't by March, he will destroy the Earth. If they do, whoever is responsible will get 10-billion yen, which equates to about 126-million US Dollars. The thing is, Koro-sensei is the best teacher these students have ever had...
    • Later on, Tadaomi, their overseer sent by the world government, also joins in as their phys-ed teacher in order to sharpen their combat skills. They also get the help of Irina Jelavic, a professional hit woman and Femme Fatale to act as their foreign language instructor.
    • At the end of the series, Nagisa becomes one for a class full of delinquents.
  • Dragon Ball has no shortage of badass mentors. Master Roshi is one of the earliest and best known examples: he may be a lecherous geezer, but he is also one of the oldest and most respected martial artists in the world, and the one who taught Goku and many of his friends the martial arts (in addition to basic life skills and arithmetic). Later on, Goku, himself, fills this role for Gohan, but not before Piccolo, whose extreme teaching methods helped Gohan grow as a fighter, in addition to helping facilitate the now-former demon king's Heel–Face Turn. Come Dragon Ball Super, Goku and Vegeta take on new mentors in Beerus and Whis, a bona-fide Destroyer Deity and his angelic attendant (who is even stronger than Beerus, at that!).
  • Colbert-sensei from The Familiar of Zero is a Technical Pacifist and vehemently opposes war, but when the students are in danger, he kicks major amounts of ass.
  • From Fullmetal Alchemist, Izumi "I'm a Housewife" Curtis. Endanger her students/child figures and you're in big trouble. Big trouble.
    • Be one of her students and you're in even bigger trouble.
  • Kumiko Yamaguchi from Gokusen is the homeroom teacher for a delinquent-filled school. However, she's also the 4th Generation female heir of a notorious yakuza gang. Indeed, she does a lot to protect (and also correct) her students...
  • Onizuka from Great Teacher Onizuka is the epitome of this. The guy took multiple gun shots to save a girl that's been slandering him and threatening his job, dived off a building multiple times to save students, biked through a building with an impending explosion, forced a student to give up her death wish, and destroyed multiple gangs.
    • The same author wrote a manga called Kamen Teacher, which is implied to take place in the same universe as GTO, and focuses on a teacher who dons a Kamen Rider-style mask in order to whip his class of delinquents into shape.
  • Meisuke Nueno, better known as Hell Teacher Nube. Harm his students, and it doesn't matter if you're a powerful ghost or demon. He will kill you.
    • Ritsuko also qualifies: despite being absolutely devoid of spiritual power, her Moment of Awesome had her, usually portrayed as being scared to the death of even casual mention of the occult, doing what she could to protect a student endangered by an evil ghost until Nube came to rescue them both.
    • And of course, there's Sexy Mentor Minako-sensei, who actually died to save little Nube's life.
  • Knight Hunters:
    • In Weiß Kreuz Glühen, history teacher Fujimiya Aya is the only person at Koua Academy to stand up to the Absurdly Powerful Student Council when they declare their control over the school, rushing to the defense of one of his students when S Class calls out a manhunt on the boy. Of course, this is mostly because both Aya and the student are undercover assassins investigating the school, although Aya probably would also have taken action to defend other innocent students if it had ever come up.
    • One of Aya's fellow teachers, Asami, is very impressed by how Aya stands up to S Class, and does her best to emulate him when she stumbles across a severely injured and obviously terrified student on the school grounds. It doesn't go well for her.
  • Aoki Daisuke from Kodomo no Jikan can be pretty badass when it comes to protecting Rin.
  • Early on in The Law of Ueki, Kobayashi (pictured) demonstrates that he may be against violence, but if you threaten or harass his students, you will wake up in a lot of pain. Also, despite his love of justice, he is very mischievous...
  • Little Witch Academia (2017), being set for the most part in a school that teaches magic, comes naturally staffed with at least reasonably competent witch professors, but Professor Ursula definitely takes the cake for measure of "most badass". She usually plays the part of a meek, soft-spoken educator, but will also effortlessly brawl giant monsters with her bare fists in defense of her students and childhood friend turned Big Bad.
  • Professor William James Moriarty of Moriarty the Patriot. He is violently protective of his students, and his default method of dealing with people who anger him is murder.
  • Koumoto Akari, of My Monster Secret, is the great-great-granddaughter of the school's Principal, the thousand-year-old demon Akane. Said demon is a recidivist troll to the students and occasionally goes on potentially world-threatening tantrums when she doesn't get her fix of sugar. Akari possesses Super-Strength and is pretty much the only thing in the world that can put her Akane her place; and the latter is very careful to not piss her off too much.
    "Carve this into your mind. The only one who's allowed to toy around with my students is me."
    Akane, moments before slicing the addressee in half with her bare hands.
  • The eponymous school of My Hero Academia is staffed primarily by professional superheroes, so naturally this trope applies to pretty much all of them, but All Might definitely takes the cake when the League of Villains break into the school and decide to lure him out by killing a few kids. All Might arrives on the scene and he is not happy, proceeds to kick the ass of every villain standing (barring Tomura Shigaraki and Kurogiri) in seconds, and then manages to inflict a No Holds Barred Beat Down on a Noumu (which was specifically created to defeat him, by the way), punching it so hard it becomes a Twinkle in the Sky.
    • And before All Might showed up, Eraser Head pretty much took on the entire League by himself, only to become overwhelmed by the Noumu, and when it was viciously beating him by crushing him, breaking both his arms and smashing his head into the floor, he still managed to stay conscious long enough to stop Shigaraki from disintegrating Tsuyu — even Shigaraki called Eraser Head "so cool" for that.
  • Basically every sensei on Naruto. Especially Naruto's own sensei, Kakashi. Mess with Kakashi's students and he will end you. He's not called the Copy Ninja for nothing. Even when Naruto, Sasuke, and Sakura get strong enough to take care of themselves and any threat that comes their way, he still protects them.
    • Might Guy is perhaps the most badass teacher in the series. He isn't only The Ace and a Manly Man, but he never loses a fight on panel until near the very end (and even then he still almost won) and one-shots one of the strongest antagonists in the series.
    • Special mention to Asuma as well, who took on a group of Sound ninja about to kill his student... and beat every single one of them in under thirty seconds. While still smoking.
    • And poor Iruka, a Chuunin Academy teacher who in Episode 1 completely fools an Ax-Crazy colleague and protects Naruto... after having a giant shuriken (among other things) embedded in his back.
    • Jiraiya. As one of the strongest characters in the series, he's badass from the word go; but its his students who really define him. Namikaze Minato, Yahiko, Nagato / Pain, Konan, and Uzumaki Naruto.
    • Tsunade too, as she taught Sakura and Shizune everything she knows and Tsunade is the World's Strongest Woman.
  • Negi Springfield from Negima! Magister Negi Magi becomes dramatically more dangerous if his students are in danger. The same goes for Takahata. If there's a queen then Negi could be considered the king; after being impaled with a stone spear he collapses in a pool of his own blood. Then person that injured him turned his attention to Negi's student... and that's when he gets mad: he tears the spear out of his body and uses it to bash the guy in the head. Also, keep in mind that he's only 10-years-old.
  • Seki-sensei from Ojamajo Doremi isn't just a Badass Teacher, she's a Badass Biker.
  • In Pokémon the Series: Sun & Moon, Professor Kukui is a competent enough teacher that it's little surprise that he can battle quite well with them. While he doesn't usually do so, he and his Braviary do save Professor Burnet from a Zerg Rush of Dragon Pokémon. (And then there's his alter-ego as the Masked Royal...) Then again, the school he teaches at is a Two-Teacher School, so he has no competition for badass teacher.
  • The titular character Heine in The Royal Tutor. He is well-versed in mathematics, history, chemistry, geography and several languages, despite having no university degree. He is also able to easily catch the already fast Leonhard on horseback who had a head start and when Fuchs and his mooks threatened to physically harm Kai, he was able to take care of them without breaking a sweat.
  • Stewart, the agent posing as a teacher in Sonic X, fell fully into the role and did everything in his power to protect the kids, most notably throwing off his orders to protect them during Chaos' rampage. Not to mention the episode where he gets captured along with some of the kids, and has to break out and protect them.
  • Soul Eater has the Shibusen faculty, with Stein as a particular example.
  • The Tales of Symphonia OVA has a scene where Raine takes out Lloyd with a piece of chalk when he was sleeping in class. And it knocked him down along with his seat. That or she caught him off guard. Kratos would be disappointed.
  • Yoko Littner from Tengen Toppa Gurren Lagann may be the queen of this trope, managing to defeat two Ganmen with just her rifle and a hoverbike in order to protect her students.
    "This will be on the test, so remember well. Don't wreck people's houses! (strafes a Ganmen with over a dozen shots) Don't take children hostage! (dodges the other Ganmen's attack) Don't threaten people with force! (finishes off the second Ganmen) That's it. Class dismissed. (Dramatic Gun Cock, the Ganmens explode) You fail!"
  • Kagami of Ultimate Otaku Teacher is perfectly willing to risk his own life and freedom to protect his students' lives and freedom. Despite not being that willing to be a teacher in the first place.
  • Yu-Gi-Oh! GX:
    • Chronos-sensei. Not only does he stand up to Camula to protect the other students who are carrying Spirit Keys (and most especially the pride of the school at the time, Kaiser Marufuji Ryou), but in season three, he puts himself in between his students and a rampaging horde of duel zombies, to delay said zombies and prevent them from stopping the students from getting to where they could get the help they needed to leave the desert dimension. And both times, he knew he was going to fail. He did it anyway. He has his bad points, but when his students are threatened, he will put his foot down (and then get knocked on his ass, but he doesn't let that get him down!).
    • You might also include Samejima, the school's headmaster. He was the one who originally trained Ryo, and was presumably no slouch. "Presumably" because he never actually won a duel on-camera. But then, there had to be a reason why he was running this place and a monastery devoted to the Cyber-Style of dueling before that...

    Comic Books 
  • The DCU:
    • Batman: Huntress is a crime-fighter by night and a high-school teacher by day. Just try to threaten "her kids".
    • Black Lightning: Jefferson Pierce is a teacher in his day job, and spends a lot of time trying to defend his students from the dangers of the streets. Often in costume.
    • Global Guardians: Chaim Levon was a Jewish school teacher before becoming the superhero Seraph and aiding Superman to dismantle bombs in Israel.
    • Wildman was the most fearless and ferocious combatant in Sgt Rocks's Easy Company. In the civilian world, he was a quiet and mild-mannered high school history teacher.
    • Wonder Woman Vol. 2: Mnemosyne is a Themysciran philosopher and teacher, who is also an Amazon with all the training, speed, and strength that entails.
  • Marvel Universe:
    • The Punisher: Frank Castle once went undercover as a substitute teacher in a high school to weed out a gang of drug dealers. He quickly developed this attitude towards the students he was teaching.
    • Spider-Man: Peter Parker was this for the brief time he worked as a science teacher at his old high school in The Amazing Spider-Man (J. Michael Straczynski). One cool moment is when he uses his Spider-Sense to catch a paper ball aimed at his head without looking.
    • X-Men: The X-Men are almost always badass, and this extends to their teaching careers at the Xavier Institute as well. Emma Frost in particular is very protective of her students, probably because two of her previous classes of students were murdered.
  • PS238: The teachers are almost all retired superheroes. This follows logically.

    Comic Strips 
  • In Frazz, Mrs. Olsen saves one of her students, Gabriella, by knocking her out of the way of an SUV driven by a texting driver. Both Mrs. Olsen and Gabriella suffer a broken arm.

    Fan Works 
  • In Amazing Fantasy, Peter is a former science teacher and ex-instructor at Avengers Academy who takes up the Big Brother Mentor role to a newly spider-powered Izuku. Being Spider-Man, Peter can wipe the floor with gangs of criminals that could seriously injure the average Pro Hero.
  • In A Boy and His Dog, Captain Komamura takes this role to Ichigo after the later took all of the former's power when protecting his family from a hollow. Not only does Komamura mentors him about his duty as a Soul Reaper, but he also teaches him to make contact with his Zanpakuto spirit.
  • Godzilla Junior becomes one in The Bridge after realizing Mariner Chibi Moon, a hyperactive fangirl he initially wrote off, was actually a lot like himself before he lost his innocence and becomes her sensei. Considering he's Godzilla and is a One-Man Army even in his unicorn form, this comes naturally.
  • The highschool history teacher Cole Anderson in Bringing Me To Life off- and on-screen saves one of his students, Max Jameson, from Cecil and his Mooks Brandon and Dillon...then offers to teach Max martial arts to defend himself.
  • In The Dark Side of the Mirror Verse, Mirror!Starlight Glimmer is this. Pinkamena describes her as a great teacher, and she is dedicated to helping others reach their full potential, but she's also The Dreaded and is implied to be extremely strong. Case in point, she mopped the floor with a stallion who was attempting to beat up Rainbow Crash with little effort, and Fluttercruel at least fears the mare could turn her into a pony pretzel with her mind if she felt like it. It's also said she trains Royal Guards.
  • Fire Emblem: Three Houses: Fifth Path: Byleth, naturally. Messing with her students is usually a good way to get the crap beaten out if you at best. She's especially protective because she already went through several of their deaths once and refuses to go through it again.
  • Futari Wa Pretty Cure Blue Moon has Ami-sensei, who, despite her ditzy nature and constant striving for a promotion she'll never attain, is a Gadgeteer Genius who built a machine to communicate across dimensions. Oh, and she's a retired Magical Girl Warrior who's aware of the danger that her students put themselves in on a regular basis. When things get serious, especially when the Damsel in Distress to whom she is an Honourary Aunt is involved, out come the plans, the super strength, and the friendship beams of death.
  • Ellen Baker in the Harry Potter/KanColle crossover Harry and the Shipgirls is an English teacher at Yokosuka. One time, when one of the cultists who worship the Abyssals attacked her class, Ellen wrestled with him to buy time for her students to escape. After he stabbed her in her gut at least twice and threw her to the ground, she staggered to her feet, picked up a tree branch, and promptly laid into him. Let's just say after that, no one in the military asks if she is good enough for the kids.
  • Harry Potter and the Methods of Rationality features Professor Quirrell, who is as unlike his canon incarnation as possible. He stuns two hundred students with one spell to save Harry (It Makes Sense in Context), can cast a Shield Charm strong enough to block fifty shield-breaking curses, glues bullies to the ceiling, and has the Pioneer Probe plaque as one of his Horcruxes.
  • In Horseshoes and Hand Grenades, we have Chuta Ohsugi who is about the exact opposite than his canon portrayal. Instead of a Butt-Monkey, we've got a determined man who is willing to go against the woman he crushed on (Sonada) with nothing more than a slipper and a costume glove, fight his chairman head on and even proclaim that he will be the next principal of Amanogawa High. Haruka Utsugi also counts as she's willing to fight off against Leo Zodiarts with nothing more than a katana. In Month of Sundays, Takashi Satake is also stepping up to be this.
  • Exaggerated in The Night Unfurls. The teacher, Kyril, witnesses his students Sanakan and Hugh being incapacitated by Shamuhaza in battle. What does he do? He Mind Rapes the being responsible for this to a Fate Worse than Death.
  • In Oh God, Not Again!, Sirius gets to become a Hogwarts professor. Yeah, you heard that right.
  • While the teachers in canon are this, in Ruby and Nora they are much more hands on.
  • Jack and Brick in Origins. While they really do care about their students, that manifests itself in teaching them how to bring each other to death's doorfor real since bacta offers a massive healing boost afterward. They wonder what the point of all this is during a relatively peaceful time, until it turns out Faster-Than-Light Travel has unforseen consequences...
  • Furutani Katsuo, resident zanjutsu teacher and Yuzu's class advisor in Phases of the Moon is this coupled with Cool Teacher. While he doesn't actually fight any of the people who bullies his class, he does make it very clear that he's firmly on his students' side, encourages his students (including Yuzu) to beat up their opponents from other classes when challenged, and likes to remind people that he was once a seated officer in Eleventh Division. And when Karin's class gets ambushed by Hollows in the living world while on a training exercise, he doesn't hesitate to fight in their defense, albeit in the background.
  • Astrid in Prodigal Son is a very competent, tough but fair mentor to the children, having taught them fighting and survival skills with the knowledge that they will eventually be savvy enough to fend for themselves against their dragon enemy. Even when she has Snotlout take over for her to spite their parents for trying to force her to quite, she was able to remind them of the basic skills they needed to survive.
  • Rosario Vampire: Brightest Darkness Act III: In chapter 41, Ms. Nekonome bravely stands up to Kuyou of all people, reminding him that he is no longer welcome at Yokai Academy and ordering him to get out. While she does lose some of her bravado when Kuyou draws his sword and comes after her, just the simple fact that she's willing to stand up to an anti-human Knight Templar who needs very little provocation to reduce humans and monsters alike to smoldering piles of ash in the first place qualifies her for this.
  • Most of the teachers in Skyhold Academy Yearbook fall under this, Bull especially. When outside forces threaten their students and actively harm one of their colleagues, they join forces to take back the school. The badassery makes sense, given that the teachers are the inner circle of Dragon Age: Inquisition transplanted into a High School AU.
  • Turning Red: Secrets of the Panda: Catherine Moore aka Xia Lee is the new biology teacher at Mei's school, and is shown to be a competent fighter, able to go toe-to-toe with Jason's men. plus, just like the rest of her female relatives, she can transform into a gian red panda.
  • Weiss Reacts: All of Beacon's staff, including the almost-literally Almighty Janitor Beth Lupin, and Cinder. Yes, even Peter Port and Tohru Honda count here. Not to mention the headmaster, Ozpin himself...
  • In canon Worm, Mrs Knott is a run-of-the-mill Computers teacher. In Recoil, she's a formidable boxer and an expert sniper. Nobody better mess with her kids ...
  • Zero no Tsukaima: Saito the Onmyoji has, in addition to the canon examples, Saito himself, after he becomes Professor of Magical Morals.

    Films — Live-Action 
  • Subverted in the film Bad Teacher, where Cameron Diaz plays it as being just as much a jerk to her students as she is to non-students.
  • Big Brother (2018): Henry Chan, ex-military martial artist played by Donnie Yen. He earns his student's attention with his strength, but he earns their respect with his kindness. When a news outlet slanders Henry and he loses his job, the students are tearful to see him go, but strive to help him back by acing their exams so the school can see the good influence he has on them.
  • In By the Sword, Max Suba, once he has Erin as a fencing student, is protective of her, and once she gets hurt, fights the already established badass teacher Villard over his teaching techniques and showing him just what happens if you are a ruthless sword fighter.
  • Played with in Gods and Generals. Stonewall Jackson was a Four-Star Badass who happened to have once been a mediocre math teacher..
  • David Niven's character in The Guns of Navarone was a chemistry teacher turned explosives expert. He's never shown around students, though..
  • Harry Potter and the Prisoner of Azkaban: He's a dick, but what does Snape do when he sees Lupin transform? Instinctively puts himself between an out-of-control werewolf and his three least favorite students. This becomes even more apparent when you take into account that this was the same werewolf that had nearly killed him as a teenager. And he didn't even have his wand!
  • Indiana Jones is never actually seen protecting his own students, but given he is a teacher with an extremely protective attitude towards kids, he probably counts.
  • Principal "Crazy Joe" Clark, from Lean on Me, comes across as a Stern Teacher, but in reality is a Badass Teacher for his entire school, chaining the doors during the school day to keep the students in and the bad influences out. Remembered largely for carrying a bullhorn and a baseball bat.
  • Kindergarten Cop. Bonus for being played by Arnold Schwarzenegger, Papa Wolf extraordinaire in his movies.
    "You hit the kid, I hit you!"
  • Australian zom-com Little Monsters has Miss Caroline become this when she has to save her kindergarten class from an outbreak of zombies while on a field trip
  • Principal Duvall in Mean Girls doesn't do anything typically badass during the film, but sometimes sheer presence is enough: looking at the man, especially when he's giving a stern lecture whilst wielding a baseball bat, just tell me you wouldn't a) hang on to his every word or b) not want to take him on in a fight.
  • In The Principal, James Belushi's character Rick, the principal in question, personally fights the Gangbangers who are turning the school he's been assigned to into a living hell.
  • In Saving Private Ryan, Captain Miller's occupation back home is a mystery to his men. It turns out he was a high school English teacher.
  • In The Substitute movies, professional mercenaries infiltrate high schools as substitute teachers to weed out the crime rings keeping the rest of the school in fear.
  • In Warrior, Brendan is a physics teacher who is also a MMA fighter.
  • In The Wrong Cheerleader Coach Flynn (played by Vivica A. Fox no less) takes it personally when somebody threatens her 'girls'. She gets to chase down the Big Bad, stun him with mace and follow through with a Bond One-Liner. Definitely not a woman to mess with.
  • X-Men Film Series:
    • Professor Charles Xavier. Specifically, with a doctorate in genetics. He can telepathically freeze entire airports full of people, co-opt the mind of anyone he can "see" and force them to be a perfect mouthpiece for himself, switch between bodies and even psychically control people if need be, despite the gravity of his puppet's own powers. And his strength has only increased with age.
    • At the end of X-Men, Magneto asks Xavier what happens when someone finds out about his mutant school, and Xavier replies that he has a great deal of pity for anyone who comes to the school looking for trouble. In X2: X-Men United, he's proven right, when the teachers and caretakers fight side by side with some of the more powerful mutant students.
    • Wolverine sarcastically claims to be an art teacher in X2: X-Men United, and serves as a substitute for Cyclops in X-Men: The Last Stand. In the new future created at the end of X-Men: Days of Future Past, it's explicitly stated that he's the history teacher. Messing with the kids (particularly Rogue) while Wolverine is babysitting is a catastrophically stupid thing to do.

  • Tamora Pierce is fond of this character type. If you're a character in one of her books who fails to take teaching seriously, you're probably a baddie. Specifically:
    • Numair from The Immortals. He's very patient and does a good job teaching Daine how to train her wild magic, given that nobody knows much of anything about it, but gods help you if you interfere. He'll demonstrate that he is, in fact, the strongest mage in Tortall.
    • The rather similar character of Niko Goldeneye in Circle of Magic as well. He doesn't go in for much combat, but he still has a temper that should not be crossed.
  • Quiet, unassuming Mr. Tidwell from Animorphs is actually a revolutionary fighter who has a symbiotic relationship with the Yeerk inside his head.
  • Miss Chadwick, the quiet math teacher from the Agatha Christie novel Cat Among the Pigeons, tackles a gunman in order to protect her fellow teachers and one of the parents. She doesn't survive the experience.
  • Miss Wilson in the Chalet School series. Leading a group of kids to safety through a secret passageway, with a gang of angry Nazis in hot pursuit? Pretty badass. Doubles as a Mama Bear moment.
  • Ciaphas Cain (Hero of the Imperium!) eventually gets to retire from inadvertently being a Badass Commissar... in order to teach another generation of Commissars. The Imperium is naturally expecting this trope to come into play, even before he starts working with three more Badass Teachers in order to protect the planet from an arm of the 13th Black Crusade.
  • Discworld:
    • Susan Sto Helit becomes one of these in Thief of Time.
    • From Interesting Times, Ronald "Teach" Saveloy, a retired schoolteacher and member of Cohen the Barbarian's Silver Horde. (At the end, he even goes berserk. After he's been mellow all his life).
    • And the Assassins' Guild School has a staffroom full of teachers who have all inhumed people at least once. When people stop and think about it, having killed somebody is, implicitly, an entry requirement for the job. And they are allowed to openly carry weapons in the classroom.
  • The Dresden Files, Has a few examples.
    • Harry Dresden himself once he takes on Molly as his apprentice.
      • Molly's teacher in Ghost Story and Cold Days is none other than Leanansidhe, who is second only in power to Queen Mab in the Winter Court
    • Harry's second Teacher and Grandfather Ebenezer McCoy. This is the guy who's responsible for Krakatoa, the New Madrid Earthquake, and Tunguska, amongst others. He's mastered the Colony Drop, and if you mess with his grandson, he will drop a satellite on your head.
    • There is Odin who is hinted to have been the teacher of the Original Merlin. He's also a Badass Santa, and mentors Harry.
  • In Farmer Boy, Almanzo's teacher, Mr. Corse, is soft-spoken and rather on the smallish side. The oldest students in the school have a tradition of beating teachers nearly to death and breaking up the school—which tradition Mr. Corse proceeds to break by driving the boys out of the school with a blacksnake whip. The description of the damage he does and his complete lack of mercy is quite disturbing—particularly when he simply coils the whip after he's done and resumes teaching as if nothing had happened.
  • De Griezelbus: In the third book, Mister Jacques is initially a Distressed Dude after he's captured by Beentjes. When he hits his Rage Breaking Point, he breaks free, smashes Beentjes, and destroys the computers that are keeping his students captive.
  • Most of the teachers in Harry Potter;
    • Mad-Eye Moody who became the new Defense Against the Dark Arts teacher in Goblet of Fire would be the straightest example. Both, the real Moody, even though he never gets a chance to actually be a badass while a teacher, and the fake Moody, who manages to do a great job of impersonating a badass.
    • Dumbledore gets special mention, as the one and only time he rebuked Professor Umbridge was when she started physically attacking one of his students. And the one and only time he ever got angry with Harry Potter was when Harry thoughtlessly suggested that Dumbledore was leaving the school unprotected. There is also his Unstoppable Rage when a bunch of Dementors showed up at a Quidditch match. And when fake Moody tries to kill Harry, our hero (along with, by extension, the readers) sees exactly why Dumbledore is the only wizard that Voldemort ever feared.
    • As does McGonagall. Mess with her, and you get a disapproving glare. Mess with one of her students or colleagues, and she takes ''four'' Stunners to the chest at age seventy and bounces back with only a walking stick to show she was hospitalized for a month. And Madam Pomfrey claims that the four people that are basically the wizard equivalent of a SWAT team would have had no chance in hell of taking her in a straight fight if they hadn't turned around and sucker punched her. Then, for an encore, she and Slughorn help an Auror take on Voldemort himself and live to tell about it, something that very few people have done.
      • Almost all of McGonagall's interactions with Umbridge in Order of the Phoenix qualify as this. She repeatedly mocks or snarks at Umbridge, who could fire her with a word to Fudge if she wished, and encourages Peeves to screw with her. And when Umbridge starts trying to pick on Harry and the other students, McGonagall does her best to stop her or thwart her.
    • Severus Snape. He was a spy for Dumbledore, could fly without a broom, and during his spying days he lied to Voldemort's face for years. And he was an innovator, too. He is in fact the Half-Blood Prince who was behind a number of innovative and sometimes nasty spells. And when he actually does teach, once you get past his Jerkassery, he is focused; he teaches with a purpose.
    • Lupin also deserves a mention, being the only member of the Order of the Phoenix other than Dumbledore to survive the battle in the Department of Mysteries unscathed. He also happened to be the first competent Defense Against the Dark Arts teacher that Harry ever had—and in order to be a competent Defense teacher, this trope is practically a job requirement. There's a reason that the three best Defense instructors Harry ever had are on this list.
    • Most, if not all, of the teachers get dangerous in the Battle of Hogwarts in the final book, using their significant magical knowhow to great effect. There's a reason that Hogwarts is often called "the safest place to keep something".
  • In Heralds of Valdemar most of the teachers at the Collegia are this. Especially the Herald ones, but a good chunk of the Bardic and even Healer teachers are not ones to mess with. Heralds just stand out because not only do they teach, they do.
    • Special mention goes to Alberich. Old, battle and fire scarred warrior long before he even became a Herald. He's the only one to escue Herald White and is the resident Weaponmaster. He teaches the student how to fight and survive in a Stern Teacher fashion. Because his teachings will not only save the lives of those the Heralds rescue but themselves. Also, should note that only with a handicap can anyone defeat him in a one-on-one battle.
  • Heretical Edge: Being a Badass Teacher is practically a job requirement ot be hired at Crossroads Academy, which is staffed by often centuries-old monster hunters.
  • The Goldfish Robot in Sophia McDougall's Mars Evacuees is a Sadist and Misplaced Kindergarten Teacher, but when its students are endangered, it flies into battle against any danger without hestitation.
  • Percy Jackson and the Olympians:
    • Paul Blofis, Percy's stepfather and English teacher proves to be this in the final book when he stabs a monster with a sword and brushes it off as 'having done fencing in college.' Then again, he had to be pretty badass just to marry a woman whose son is half god in the first place.
    • There's also Mr. Brunner (who is present throughout the entirety of The Camp Half-Blood Series), willing to defend his students at any cost, even fighting the Titan King Kronos himself. Then again, him being the ancient centaur Chiron helps with that. He's also the closest thing the series has to a Big Good.
  • Many of the mentors in various fields in Ranger's Apprentice are badasses, but special mention has to go to Halt, a Living Legend Badass Normal whose wit is as sharp as his arrows. Mess with Will or Horace, and you will regret it.
  • Reign of the Seven Spellblades: One of Kimberly Magic Academy's major purposes is to train the order of Military Mages known as the Gnostic Hunters, who battle Alien Invasions sent by the gods of other worlds and root out their earthly cults. Consequently, every member of the faculty is a badass even by mage standards: several instructors are current or former Gnostic Hunters themselves, and they include among their number the wielders of at least two of the eponymous seven spellblades. At the top is Headmistress Esmeralda, the Witch of Kimberly, who is credibly believed to be one of the most powerful mages in recorded history.
  • Sherlock Holmes' Arch-Nemesis Professor Moriarty who is this, while being a Chess Master.
  • In the Star Trek: Deep Space Nine novel "Fallen Heroes", schoolteacher Keiko O'Brian holds off the marauding Bekkir long enough for Jake and Nog to escape. It gets Reset Buttoned, but it was still pretty awesome.
    • This also qualifies as a Mama Bear moment, because Keiko's primary motivation was to protect her daughter Molly who was also with Jake and Nog.
  • Tales of the Astonishing Black Spark has Nikolas Tess, who having the same powers over electricity as the titular hero trains him in both utilizing the ability, and getting his butt kicked.
  • The short story This Year's Class Picture by Dan Simmons has one of these who actually teaches a class of zombies after the Zombie Apocalypse, and sits in a bell tower daily to mow down zombies invading her school. When the outside zombies mob together to attack her zombie schoolchildren, she burns them alive in a freakin' gasoline moat.
  • Time Scout: Kit and Malcolm take it upon themselves to manage Margo's education in badassery. They hire Ann and Sven as tutors for guns and close-quarters combat; two separate sub-badassitudes, and not the sum.
  • Tunnel in the Sky has Deacon Matson. Short an eye and some fingers and a decorated survivor of the first interstellar expeditions. That includes an award for being the sole survivor of a disaster. He teaches college-level survival to high school students and believes that, instead of the sissy method of giving them any desired weapon, the students should go unarmed to a hostile ecosystem for the final test.
  • Starship Troopers has Jean Dubois, Rico's History and Moral Philosophy teacher, retired Lt. Colonel in the Mobile Infantry, who lost an arm in combat.
  • Dimitri Belikov from Vampire Academy. A badass dhampir guardian who teaches Rose how to use a stake. Eventually fights in a huge battle against Strigoi and takes several down in the process. Characters outright use the word "badass" to describe him!

  • Sister Montoya from World War Z. A badass nun teacher, who went on to join the army when they re-organized to start fighting zombies effectively.

  • In David Klass' novel You Don't Know Me Mr. Steenwilly, the protagonist John's music teacher, is the only adult to notice John's mother's boyfriend was physically abusing him and even took the initiative to follow him home one day. When the abusive boyfriend was beating John senseless, Mr. Steenwilly jumped in and saved John's life.

    Live-Action TV 
  • Though she never actually takes anyone down physically, Laura Roslin of Battlestar Galactica probably counts, considering she is a political badass who used to be a school teacher and will airlock anyone she sees as a threat to her people.
  • In Black Lightning (2018), the titular superhero's day job is that of a high school principal.
  • Harry Senate from Boston Public.
  • A sort of weird twist on this trope from Walter White of Breaking Bad. Walt is a registered badass, being a rising drug-lord and slowly amassing a criminal empire while on the surface being a gentle high-school Chemistry teacher.... but those two elements don't overlap. Walt sees teaching as a soul-sucking, miserable job he took only to support his family and clearly enjoys the rush and thrill of his criminal lifestyle much more. He couldn't give two shits about his equally-apathetic students, and is shown casually handing out failing grades and shooting down excuses for why they didn't study.
  • Giles from Buffy the Vampire Slayer.
    • Technically he's just the school librarian, he doesn't actually teach any classes. Except private ones after hours about vampire slaying for a select audience, of course.
    • Riley Finn was a badass TA.
    • Robin Wood is a Badass school principal and son of a Slayer. Even Buffy is amazed at how capable he is.
    • Miss LeHane worked as one, and did a pretty good job of it as well, trying to stop the school from being turned into vampires. She's the freaking Slayer. She whips Drusilia without breaking a sweat. And she's savvy enough to do well on the teacher part.
  • The Hoshikawa siblings of Chikyuu Sentai Fiveman are all Badass Teachers.
  • Ian Chesterton and Barbara Wright from Doctor Who.
    • Hell, the Doctor himself in the episode School Reunion. And John Smith ends up being one by sacrificing his life in "Human Nature"/"The Family of Blood".
    • Danny Pink, former British soldier turned math teacher, was able to resist being turned into a Cyberman after being killed and subsequently foiled the Master's latest plot to defeat the Doctor and humanity.
    • Clara Oswald, who rides a motorcycle (which is enough to qualify her right there), steps away from her class because a paramilitary organization calls upon her whenever the Doctor isn't available, and is arguably the most powerful companion in the show's long history.
  • Game of Thrones: Syrio Forel is Arya's unrivaled sword master.
  • The protagonist of The Greatest American Hero.
  • Takeshi Hongo of Kamen Rider would like to do a Rider Kick to the monsters who harms not just his students, but to those who harm other people as well. And he's a Badass Biker too!
  • Kamen Rider Fourze, being a Kamen Rider series set in an American-style high school, naturally has several. Movie Wars Ultimatum, which takes place five years after the end of the series, shows that Gentaro himself came back to teach at his old school and still becomes Fourze to fight the random monsters that crop up once in a blue moon.
  • Al's grade school librarian in Married... with Children.
  • Nowhere Boys: Ellen in the final two seasons.
  • Tommy Oliver in Power Rangers: Dino Thunder. He doesn't want to be badass, he just wants to be an ordinary science teacher. Nonetheless, he shows that he's more than willing to step back onto the battlefield after years of retirement if his students are threatened.
  • Santiago Mancilla in Rebelde Way. You don't mess with Third Year. Period.
  • World History Professor Milton Fine, alias Brainiac on Smallville combines this with Evil Teacher and Badass Bookworm for truly dangerous results.
  • Most Star Trek vets end up becoming instructors at Starfleet Academy if they aren't promoted to Captain in the future.
    SFDebris: Our last stop's Reg, who has a special shuttlecraft waiting... Because why wouldn't he? He's a teacher! I remember when I took my first trip in the school helicopter. (contented sigh)
  • In Teen Wolf, Ms. Morrell looks to be shaping up as one, if the end of season two is anything to go by, she's got ties to Deaton's past.
    • Coach Finstock has a touch of this; ask the orderlies from Eichen House. Once they've stopped writing in pain on the music room floor.
  • The Twilight Zone (1985): In "Teacher's Aide", Miss Peters is possessed by the spirit of the gargoyle that sits on the roof of the tough Inner City School where she teaches English. She goes from being a dedicated teacher whom the students don't respect to one who responds to any act of insubordination with violence. Miss Peters begins to worry that there is something seriously wrong with her because she can't control this behavior. When a gang member named Wizard plans to attack her, she senses the approaching assault and is able to defeat him. Miss Peter is about to kill him when she sees her reflection and realizes that she has now become a gargoyle herself. She is disgusted by her use of violence as she is not that kind of person. Lightning strikes the gargoyle and she returns to normal. Grateful to Miss Peters for not finishing him off when she had the chance, Wizard thanks her from the bottom of his heart and helps her up.
  • Ultra Series
    • The human form of Ultraman 80, Takeshi Yamato, took teaching middle school students as his job. Considering what he can do in Ultraman form, it's not a good idea to threaten his students.
    • Also, the original Ultraman qualifies, somewhat. Not his human host, but Ultraman himself, who was actually a university professor back on M78.
  • In The Vampire Diaries Alaric Saltzman, history teacher by day, vampire hunter by night. On a few happy occasions, these two interests have synergized when he finds old documents about vampires.
  • Mr Rimmer, headmaster of Waterloo Road.

    Video Games 
  • It's not touched upon much in the games, but Jeanne, who is every bit as badass as Bayonetta moonlights as a high school teacher when she's not doing her witch thing.
  • Attack the Blood Raven initiates, especially the ones trained by Dawn of War's Cyrus, I dare you. Even if you're a Super-Soldier enhanced with demonic power.
  • Final Fantasy:
    • The instructors of Garden in Final Fantasy VIII qualify for this. Case in point: Quistis Trepe. How did she once assist her students on the field? By taking down the giant spider robot that's pursuing them with a gatling gun.
    • Serah Farron of Final Fantasy's "Lightning Saga" took a job as a teacher in the three years between the first game and Final Fantasy XIII-2. She earned the nickname of "Meanie Miss Farron" for how she reacts to students not doing their homework. She's also an ex-l'Cie, which means that she knows how to use magic,* and she's currently living on Gran Pulse, which means she's a crack shot with a bow.
  • Fire Emblem: Three Houses is set in a military academy, so naturally, all of the teachers (including the protagonist themselves) are just as capable on the battlefield as they are in the classroom.
  • The Didact from Halo once taught at the "College of Strategic Defense of the Mantle", or simply the War College; it was in fact where he gained the name "Didact". He's also the leader of the Prometheans, the highest order of Forerunner Warrior-Servants, and one of the most capable warriors in the galaxy's known history.
  • The Legend of Heroes: Trails of Cold Steel has a lot of badass teachers who work at Thors Military Academy; the principal is a retired Four-Star Badass who uses a large spear, the school nurse is a Friendly Sniper, the historian is secretly the right hand man of the most powerful Church Militant, the math and science teacher is a powerful arte user in his own right, the military officer takes on robots with his sword, and the homeroom teacher of the heroes class is one of the most famous bracers of the empire. Combined with the off-duty Oroborous Ninja Maid who manages Class VII's dormitory, they managed to make a better showing for themselves in the final battle of the first game than the entire First Armored Division. By Cold Steel III, Rean ends up becoming this alongside Towa, Randy, Michael, and Aurelia.
  • Mass Effect 3: Jack. Also a Cool Teacher, judging by her students' comments towards her.
  • Cyrus from Octopath Traveler is a professor, and he's just as combat-capable as any of the other characters are. He has no hesitation when it comes to fighting any of his chapter bosses, even though two of them go One-Winged Angel.
  • Pokémon:
    • Professor Sycamore in Pokémon X and Y is unlike any Pokémon Professor in previous games in that you can actually challenge him to Pokémon battles from time to time.
    • In Pokémon Sun and Moon, we have Professor Kukui. First of all, he studies Pokémon moves by actively taking them! Second of all, he's responsible for having the idea of building a Pokémon League in Alola, and third he's the final battle before you become champion! He poses quite a challenge at that.
    • In Pokémon Scarlet and Violet, the various teachers of the Academy are all competent trainers in their own right. The most prominent examples would be Director Clavell, who has a fairly diverse team complete with the starter that's strongest against yours as well as art teacher Hassell, who happens to be a member of the Elite Four specializing in Dragon-types.
  • Kogoro is Mii's tutor in Project × Zone, as he tutors Mii while doing his detective work at the same time. He's also her Battle Butler.
  • Professor Layton: The titular professor, although we don't see a great deal of him interacting with his actual students in the archaeology classes he teaches, is certainly this for his apprentice Luke.
  • All three teachers in the Rival Schools series — Hayato Nekketsu of Taiyo High, and Hideo Shimazu and Kyoko Minazuki of Justice High — exhibit this trope to varying degrees.
  • The Secret World features this in spades from Headmaster Hayden Montag and Ms Annabel Usher of Innsmouth Academy; both of them are trained mages with encyclopedic knowledge of the Secret World, so they're already pretty high on the badass scale, but the fact that they're staff members at one of the most disaster-prone schools in the United States just kicks their credentials into overdrive. Plus, Innsmouth Academy has recently been enveloped by the same catastrophe as the rest of Solomon Island, leaving the place infested with feral familiars and spectral alumni... and yet, Montag and Usher are still alive, still protecting their remaining student, and still weathering the storm. Plus, Montag has personal experience on killing familiars with "a swift, decapitating blow with a spade."
    A teacher is only as good as his tools!
  • Street Fighter, being a fighting game series that takes place in a World of Badass, has no shortage of badass teachers. In Street Fighter III, Ken takes Sean under his wing and trains him. Meanwhile, in Street Fighter 6, Luke fills this role for the player in World Tour mode (and by extension, every other member of the playable roster), as does Chun-Li for her adopted daughter Li-Fen.
  • Raine of Tales of Symphonia continues to teach her three students Lloyd, Colette, and Genis while they are traveling across the world on their quest. Then she fights monsters and bandits and half-elves and brings down holy light on enemies with devastating power. Her role as the group's primary healer further cements her as a Badass Teacher, since she has spells that are used for the express purpose of protecting her students from harm.
  • Keine Kamishirasawa of the Touhou Project series. Half-Beast history teacher and protector of the human village. Best portrayed in this fanvid.
  • Lee of The Walking Dead was a university history professor before the outbreak, and the fact he was convicted for killing a man should tell you he's not to be messed with.
  • The Wonderful 101 features Mr. Wedgewood, aka Wonder Red and the leader of the eponymous heroes. The beginning of the game shows him getting separated from his students, and the rest of the game involves him rescuing them and saving the rest of the planet as well.
  • Trying to attack a teacher or kill one of her students in front of her in Yandere Simulator tends to be very, very risky. She'll pin the Villain Protagonist to the ground if she doesn't have the proper stats, giving the player a Nonstandard Game Over. According to YandereDev, all teachers at Akademi High were required to have self-defense training after an incident in 1989, involving the murder of one student by Ryoba Aishi, who would become Yandere-chan's mother.
    "Just what do you think you're doing?"

    Visual Novels 
  • Yui Shishido, or "Yui-sensei," from Corpse Party. What does she do when her students get trapped in a Dark World with seemingly no way out? She still tries to ensure her students' safety. When a ghost offers to let her go if she sacrifices her students, Yui-sensei tells him to stay the hell away from her students. Keep in mind, at the time, she was also trapped under a cabinet filled with knives. Not only does she keep rejecting the ghost's offers, but she manages to free herself. She even pulls a Heroic Sacrifice to ensure that Yoshiki and Ayumi escape a classroom before it falls apart. Not only that, but it's revealed she's encountered Heavenly Host before, and survived. Yui-sensei never abandons her students.
  • Souichirou Kuzuki in Fate/stay night in the Unlimited Blade Works route. The Drifter who randomly came to town prior to the story and stayed at the local shrine. Despite being a perfectly normal human, he becomes the suspect of who Servant Caster's Master is. Simple mission: shoot him with a sleeping spell. If he is the Master then job well done, and if not then no harm done. Of course this doesn't turn out well when Caster warps in and saves him. But the battle is on our heroes' side! They've got Saber, the woman who is the strongest Servant! She gets past Caster and goes for Souichirou! And THWACK. Souichirou counters and proceeds to unleash a Spam Attack on Fist of the North Star levels. Yes, Souichirou just beat up King Arthur with his bare hands.
    • Bonus points for in the 2015 version, he is voiced by none other than Lex Lang himself.
    • And then if you think back a day or two ago, this means he was also the one who snapped Rider's neck in twain.
      • Even after Archer betrays Caster and kills her, he's back to being a normal human, he challenges Archer to a one-on-one battle despite knowing he's going to be killed in one hit.
    • Although not on Kuzuki´s level, Taiga is a 5th Dan in Kendo (who could have gotten a lot further if her little strap on her shinai did not get her banned from most tournaments) and a swordsman on level with Shiki Ryougi.
  • Magical Diary gives us Professor Potsdam. Sweet little old lady who calls her students such things as "starshines" and "cygnet" in utter sincerity, doesn't seem to quite get the idea of discipline...and is over six hundred years old, with all the power to match. When it comes to it, Damien runs rather than face her on her own ground. Not that she can keep him from coming back for the May Ball, if you decide to take him back.
  • Yumi Matsumiya from True Love Junai Monogatari doesn't look like this, but fully shows why she deserves this title when she and the MC find out that her fellow teacher Mikazaki is sexually harrassing Mayumi and when a drunkard beats the shit outta the MC when he tries to protect her from him.
  • In the opening of Tsukihime, Shiki gets visited by Aoko Aozaki, and by the end of their little sessions, calls her Sensei from then on. Cue Melty Blood, where Aoko is a Kung-Fu Wizard specializing in Slow Lasers.

  • In the Ask a Pony blog Ask Hoops and Dumbbell, Dumbbell is a currently a Badass Student Teacher. Before going for his Teaching License, he was offered a Pro Boxing position. It's been a few years, but he's still good enough to drop an unlucky mugger.
  • Coach Callahan from Tales of MU. Aside from teaching such mundane classes as "Mixed Melee" and "Fighting to Disable", she is also one of the worst war criminals alive today. In her past, she has committed multiple genocides, stopped giants from taking over the world more than once, and has been charged with multiple counts of attempted deicide (most nations do not have laws against successful deicide).
  • The faculty of Beacon in RWBY are all skilled Huntsmen and Huntresses. The most notable examples are Glynda Goodwitch, who can repair entire buildings with a flick of her wand and can take down Grimm without even looking, Professor Port, who treats Grimm like any Great White Hunter would, and Doctor Bartholomew Oobleck, who is a bit more bookish than the other two but can total Mini-Mecha with one hit from his mace/napalm launcher/thermos. The most badass, however, is headmaster Ozpin, who puts up one hell of a fight against a Cinder who has the entirety of the Fall Maiden's power, landing multiple hits on her in quick succession.
  • Similarly, most of the teachers at Whateley Academy in the Whateley Universe, since many of them are retired superheroes. Even more frightening, some of them are retired supervillains.
    • Special mention may go to Mrs. Ryan, a kindly old lady who teaches Costume Shop I. She's very mild-mannered, knows her stuff, happily offers advice to any student who comes looking, and used to be the notorious European A-List supervillain, Lady Hydra. Most students underestimate her once. Very few do so twice.
  • In Yandere High School, the gym teacher, Rowan, is a SWAT person. His wife, Okami, the main teacher is also on the team.

    • Avatar: The Last Airbender:
      • The core of the Order of the White Lotus is made up of Cool Old Guy Badass Teachers: Iroh, Pakku, Bumi, Jeong Jeong, and Piandao.
      • Also, Gyatso, the Actual Pacifist air monk. He took on a platoon of powerful firebenders, while they were juiced up on the comet that made each of them into a walking, talking, armored Person of Mass Destruction. And killed. Them. All. As they brought him down.
      • Toph Beifong as well. She joins the group in order to teach earthbending to Aang, and she's pretty much made of badass. She also opened up an academy after the war to spread her knowledge of metalbending, which she invented.
    • The Legend of Korra: Aang and Katara's son Tenzin, the world's only master airbender. He shows himself to be quite badass, taking out chi-blockers and one of Sato's mechas by himself, and has passed on his skills to his three Badass Adorable children. Tenzin really turns it up when he takes on Zaheer, who has only been seen curb stomping opponents, and is able to hold his own against all 4 members of the Red Lotus until the finally overtake him.
  • Laid-back Hippie Teacher Mr. Van Dreissen attacks a guest speaker (somewhat wimpily) when Beavis And Butthead claim the speaker "touched" them.
    • In a later episode Teacher/Coach Buzzcut walks in on the same speaker threatening the duo. Said speaker then unwisely attempts an attack on Buzzcut, an ex-Marine, who proceeds to beat the stuffing out of him.
      "I do the ass-kicking around here!"
    • Van Dreissen's real Moment of Awesome comes in Incognito, where not only does he fail to show anything resembling fear when an unknown assailant shoots through the window of his classroom, after when Earl shoots back, driving the attacker off, Van Dreissen calmly confiscates Earl's pistol and Earl complies. Sure it was supposed to be a satire about how desensitized to violence everybody has become, but it ends up making Van Dreissen look like a fearless Badass Pacifist.
  • The title character in the Pakistani show Burka Avenger- a schoolteacher who literally uses books and pens as weapons in the In-Universe martial art Takht Kabaddi to protect access to education and women's rights.
  • In the Code Lyoko episode "False Start", Jim becomes one, fighting Xana's monsters at Kadic while the regular cast battles the villain on Lyoko.

  • In The Long Long Holiday, Mr. Herbin turns out to be Sparrowhawk, the local Rebel Leader.
  • Ms. Frizzle from The Magic School Bus. C'mon, who wouldn't want to go one of her field-trips? (Besides Arnold, of course).
  • The Flexer Teacher from Mixels. She is serious when it comes to teaching, but will be first in line to protect her students from any threat that comes their way, and ends up being the leading Mixel in a Mix that stops a rampaging Mixelopter.
  • Principal Bump from The Owl House. When faced with a threat to his students' ability to study different schools of magic, his response is to lead them into battle.
  • Some of the teachers from Recess in Recess: School's Out.
    • Of the five named faculty, three were accomplished martial artists, one was able to use his Janitorial Supplies as Improvised Weapons, and the other one was a Hippie Teacher as well as The Cutie, and showed a perfect example of Beware the Nice Ones. The principal handled capture pretty nicely as well. Course, one scene had all the teachers rappelling into the cafeteria to help the kids in the fight against the Big Bad.note 
    • Especially effective in that of the four named faculty, two are the main antagonists of the series, one an Apathetic Teacher who wants nothing more than to move up the career path and stop dealing with children, and the other is the very essence of a kids show Sadist Teacher. But if you mess with their kids, you're going down hard.
    • One episode had a substitute teacher fall into this trope. The gang goes to school, expecting a free day, only to be greeted by a teacher, whom Spinelli describes, after seeing some of his actions, having "zero fear."
  • Principal Seymour Skinner from The Simpsons. While more of a Retired Badass and a Butt-Monkey in his civilian life, Skinner is a Vietnam veteran and was a relatively successful military officer back in the day. While he usually goes out of his way to avoid conflict, he has no qualms about kicking serious ass if the situation (rarely) calls for it.
    • Case in point, beating up the blue haired lawyer and two hired goons after being threatened with a lawsuit over just a trivial copyright.
  • Star Wars: The Clone Wars: Anakin is this to Ahsoka. Pretty much any Jedi with a Padawan counts as well.
  • The Venture Bros.: Professor Victor Von Helping. He is a Cool Teacher who convinces Dean to embrace science and take his botany class. The Monarch and 21, assigned to antagonize the Science Hero, break into the classroom. When they declare their hostility, he flatly declares he will not fight them. When they attack anyway, he does not flinch at a punch to the face or a Groin Attack. But when they threaten Sirena, it hits his Berserk Button. He stares down The Monarch with "Uh-Oh" Eyes and starts Burning with Anger — hot enough to burn away his disguise and reveal the way he must have looked and behaved before his Meaningful Rename. The villains immediately regret their mistake, and only Dean's intervention spares them a serious beatdown.
    Von Helping: Enough! Do as you like to me, but YOU DO NOT THREATEN MY STUDENTS! ... How do you like facing the full wrath of Professor Victor Von Hellfire?!
  • Xavier, Wolverine, and Storm in X-Men: Evolution, along with Hank McCoy who was pretty tough before mutating into a blue, furry form.

  • Drill sergeants in general.
  • In the Finnish Army, schoolteachers are referred as reserve officers.
  • Because of the threat of suicide bombings against a certain girls school in Afghanistan, the complex was walled with only one gate placed far away from the main school building. At this gate a single teacher would sit, watching the gate. If a suicide bomber entered the teacher would attack him and try to detonate the explosive, killing them both. And if that's not badass enough, the teachers were 50 year-old women.
  • Dr. Liviu Librescu of Virginia Tech, personally kept the door shut to prevent gunman Seung-Hui Cho from entering the classroom so his students could escape. It took five shots to take him down, the last one having to be a headshot. All but three of his students managed to escape through the windows of his classroom, with only one of the remaining students dying. Of course, he had a history, since surviving the Holocaust takes a Determinator in itself...
    • The same can be said for the four other (murdered) professors who attempted to confront or stop Cho from hurting their students. Professor Kevin Granata had managed to get his class of 20 students into his office where the door could be locked. He immediately went out to investigate the shooting. Sadly he was shot and killed in a stairwell alongside his colleague Professor Wally Grant, who survived his wounds. Instructor Jocelyne Couture-Nowak, alongside student Henry Lee died attempting to barricade the door to her French Classroom. Graduate assistant Haiyan Cheng was substituting for a Professor, but managed to save his classroom as he and a student noticed the shooter heading for his classroom, letting the class barricade the classroom door in time.

    • For the Confederates, Stonewall Jackson was a professor of physics at the Virginia Military Institute prior to the war, and is widely regarded as the South's strongest tactician (although Bunny-Ears Lawyer also applies in his case, hindering his effectiveness as a teacher and his ability to work with other Confederate officers).
  • Dr. David Benke, a math teacher at Deer Creek Middle School in Denver, tackled a gunman when he tried to attack the school. In a letter to the public explaining what happened, he wrote, "If we could have told the students what we felt before the incident happened we would have said, 'Not on my watch. On my watch you are going to be as safe as I can make you.'"
  • At a university-type Military Academy, many of the professors are usually commissioned officers.
  • In Hanover, Germany, a 37-year-old kindergarten teacher named Ina Koenig saw one of her students fall down a mine shaft on a field trip. Immediately, she jumped in after him and kept his head above the extremely cold water at the bottom for two hours until help arrived, saving his life.
  • The Sandy Hook shooting gave light to many badass teachers:
    • Vicki Soto, a first-grade teacher, hid her kids in closets/cabinets and told the shooter that the kids were in an auditorium/gym. The shooter proceeded to shoot the teacher, but the kids survived. The mayor of Newtown wants to name one of the schools after her for her heroism. And she was all of twenty-seven.
    • One of the teachers turned on the PA system to warn the rest of the school of the shooting.
    • How did the principal die? She died lunging after the shooter, trying to stop him herself, probably knowing she was going to die.
  • Jane Haining and Sara Salkahazi, two schoolteachers who died in World War II for refusing to abandon their pupils, double as this and Badass Preachers (Haining was a missionary of the Church of Scotland, Salkahazi was a nun).
  • Professor Badass. Otherwise known outside Memetic Mutation as Kevin Stewart. And no, this isn't a photo shoot - this is how he rocks up to college on an ordinary day.
  • Badass school receptionist in the form of Antoinette Tuff, who managed to stop an armed gunman from hurting a single student. How? By simply talking to him, remaining calm, and showing some compassion. She managed to keep her cool the whole time until police arrived, at which point she admitted to the 911 respondent (who had been listening in the whole time) that she'd been scared to death. Again, not a single person was hurt.
  • Principal Susan Jordan, of an elementary school near Indianapolis, Indiana, died on January 26, 2016 when she saw a bus suddenly jump the curb and was rolling towards two students. Without hesitation, she rushed headlong at the two children in harms way and pushed them out of the way while being fatally struck by the bus.
  • Dave Sanders, the only teacher to die during the Columbine High School massacre. When the gunmen started firing outside the school, he ran to the cafeteria and sounded the alarm. He, along with two of the school's janitors, helped get more than 100 students out of the path of danger by herding them away from the shooters, who arrived in a nearly empty cafeteria. Sanders was in the upstairs hall trying to hide students when he was shot from behind in the torso, head, and neck. He managed to get himself into a science lab. Student Deirdra Kucera posted a sign in the lab window, "1 BLEEDING TO DEATH", and others alerted 911 dispatchers, but help never came because the police feared it was a ruse by the shooters. Sanders bled out in the lab.
  • Twenty-year-old Mary Gibbs of the Faraday School Kidnapping in 1972, who was taken hostage along with her six pupils, forced into a van at gunpoint and driven into a remote area in the Australian bush. When their kidnappers left to collect their ransom at around five o'clock in the morning, Gibbs kicked out one of the door panels of the van with her heavy, platform-heeled boots, then led the girls through the bush in the dark until they found help several kilometres away. Three months later she was awarded a George Medal for her bravery.
  • Liam Neeson trained as teacher in Newcastle. He was dismissed after punching a student in the face for pulling a knife on him.

It's not everyday you see your science teacher and school principal trying to kill each other Mortal Kombat style.

How well does it match the trope?
