Abraham: Feigned frailty, no "En garde"... Have you no honor?Sometimes you have a teacher who is not a sadist, particularly strict, or overly nice. They are just a regular teacher. 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 be 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. 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
- 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!"
- 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.
- 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.
- Negi Springfield from Mahou Sensei Negima! 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.
- 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 Crowning 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.
- 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...
- Seki-sensei from Ojamajo Doremi isn't just a Badass Teacher, she's a Badass Biker.
- 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.
- 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...
- In Wei▀ Kreuz Gluhen, 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.
- Soul Eater has the Shibusen faculty, with Stein as a particular example.
- 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...
- The Tales of Symphonia OVA has a scene where Raine takes out Lloyd with a piece of chalk when he was
not paying attentionsleeping in class. And it knocked him down along with his seat. That or she caught him off guard. Kratos would be disappointed.
- Basically every sensei on Naruto. Especially Kakashi.
- Maito Gai is perhaps the most Badass teacher in the series. He isn't only The Ace and Rated M for Manly, but he has never lost a fight on panel and has one-shotted one of the strongest characters in the series.
- Special mention to Asuma as well, who took on a group of Sound nin 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 one 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.
- 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.
- Kagami of Denpa Kyoshi 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.
- 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.
- Spider-Man, for the brief time he worked as a science teacher at his old high school.
- The Huntress, of the Batfamily.
- Black Lightning is also 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.
- Chaim Levon from the Global Guardians was a Jewish school teacher before becoming the super hero Seraph and aiding Superman to dismantle bombs in Israel.
- 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.
- The teachers at PS238 are almost all retired superheroes. This follows logically.
- 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.
- In Oh God Not Again!!, Sirius gets to become a Hogwarts professor. Yeah, you heard that right.
- 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 Distressed Damsel to whom she is an Honourary Aunt is involved, out come the plans, the super strength, and the friendship beams of death.
- 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.
- Jack and Brick in Origins, a Mass Effect/Star Wars/Borderlands/Halo Massive Multiplayer Crossover. While they really do care about their students, that manifests itself in teaching them how to bring each other to death's door—for 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....
- 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.
- 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.
- 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.
- 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.
- 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 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.
- 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 ...
- Kindergarten Cop. Bonus for being played by Arnold Schwarzenegger, Papa Wolf extraordinaire in his movies.
"You hit the kid, I hit you!"
- 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 Substitute movies, professional mercenaries infiltrate high schools as substitute teachers to weed out the crime rings keeping the rest of the school in fear.
- David Niven's character in The Guns of Navarone was a chemistry teacher turned explosives expert. He's never shown around students, though...
- 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.
- 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.
- 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.
- Harry Potter and the Prisoner of Azkaban: He's a dick, but what does Snape do when he sees Lupin transformed? 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!
- Professor Charles Xavier. Specifically, with a doctorate in genetics.
- 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.
- 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.
- In Warrior, Brendan is a physics teacher who is also a MMA fighter.
- 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.
- Quiet, unassuming Mr. Tidwell from Animorphs is actually a revolutionary fighter who has a symbiotic relationship with the Yeerk inside his head.
- Susan Sto Helit from Discworld becomes one of these in Thief of Time.
- From "Interesting Times", Teach. (At the end, he even goes berserk. After he's been mellow all his life).
- Most of the teachers in Harry Potter;
- Mad-Eye Moody 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.
- 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. 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 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".
- 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
- There is Odin who is hinted to be the teacher of the Original Merlin
- Harry Dresden himself once he takes on Molly as his apprentice.
- 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.
- 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.
Five three and a buck even, she'd protected her whole Sunday school class for nine days with nothing but a six-foot iron candlestick.
- 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.
- 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.
- 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 anyting 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.
- 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? I'd say that's pretty Badass. Doubles as a Mama Bear moment.
- Time Scout: Kit and Malcolm take it upon themselves to manage Margo's education in badassery. They hire Ann and Sven as tutor's for guns and close-quarters combat; two seperate sub-badassitudes, and not the sum.
- 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.
- Percy Jackson and the Olympians: Paul Blofis, Percy's step-father and English teacher proves to be this in the final book when he stabs a monster he can't even see with a sword and brushes it off as 'having done fencing in college.' Then again he had to be pretty badass just marry a woman's whose son is half god in the first place.
- 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.
- 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.
- 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!
- 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.
- In The 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 scared 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.
- The Goldfish Robot in Sophia Mc Dougall'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.
Live Action TV
- 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!
- 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.
- 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 of how capable he is.
- Miss Le Hane worked as one, and did a pretty good job of it as well, trying to stop the school from being turned into vampires. Bad Ass? She's the freaking Slayer. She whips Drusilia without breaking a sweat. And she's savvy enough to do well on the teacher part.
- Harry Senate from Boston Public.
- 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.
- The protagonist of The Greatest American Hero
- The Hoshikawa siblings of Chikyuu Sentai Fiveman are all Badass Teachers.
- 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)
- Ultra Series
- The human form of Ultraman Eighty, Takeshi Yamato, took elementary school teaching 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 on his home planet.
- Mr Rimmer, headmaster of Waterloo Road.
- World History Professor Milton Fine, alias Brainiac on Smallville combines this with Evil Teacher and Badass Bookworm for truly dangerous results.
- 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.
- 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.
- 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.
- Al's grade school librarian in Married... with Children
- 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.
- 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.
- 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.
- 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.
- Attack the Blood Raven initiates, especially the ones trained by Cyrus, I dare you. Even if you're a Super Soldier enhanced with demonic power.
- 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.
- Keine Kamishirasawa of the Touhou series. Half-Beast history teacher and protector of the human village. Best portrayed in this fanvid.
- Professor Layton, 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.
- Jack in Mass Effect 3. Also a Cool Teacher, judging by her students' comments towards her.
- 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.
- 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.
- 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.
- Professor Sycamore in PokÚmon 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.
- Kogoro is Mii's tutor in Project X Zone, as he tutors Mii while doing his detective work at the same time. He's also her Battle Butler.
- Go on, try to attack a teacher or kill one of her students in front of her in Yandere Simulator. Just know that she'll pin the Villain Protagonist to the ground if you don't have the proper stats, giving you a Non-Standard Game Over.
"Just what do you think you're doing?"
- 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´ve gotten alot further if her little strap on her shinai didn´t ban her from most tournaments) and a swordsman on level with Shiki Ryougi.
- 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 Frickin' Laser Beams.
- 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.
- Sandaur'recherrai Val'Illhar'dro of Drowtales is the combat instructor of Orthorbbae and it is a simple task for him to beat just about any opponents with ease and more then willing to use a Groin Attack to do it. When his clan left Chel, he went with them to their home city of Nuqrah'shareh and taught the students who were there as well. When he comes across a group of rebels attacking his students, he charged in and killed all of them, unarmed, unarmoured and without taking a single hit.
- Mr. Sly in Destiny Fails Us.
- James Eglamore in Gunnerkrigg Court. As was his predecessor.
- Not to mention Jones, who mentors mediums and beat Eglamore in a sword fight while unarmed. By blocking the sword with her face.
- Kat's parents are scientists at the Court and she follows their footsteps. Her mother built a magitek computer to trap a body-stealing demon and in youth was building robots.
- Mr. Raven in El Goonish Shive. He happens to be the son of an immortal, making him very old and very dangerous. Good with a Sword Cane, and can summon a flock of exploding crows. Another case of don't mess with the students.
- Largo from Megatokyo is a subversion,because while he tries to do this, he just as often leads his students into danger.
"Doesn't Great Teacher Largo make you want to learn English so you can understand what he's saying?"
- Although the fact that he's teaching an English class in Japan and doesn't speak Japanese is interesting. But they're still learning somehow.
- Any of the teachers in MSF High.
- Miranda Deegan. A very evil mage once killed several of her students to get to her. She banished him to a realm of Mind Rape.
- In Girl Genius, the caretaker for the students on Castle Wulfenbach is Von Pinn. Don't mess with Von Pinn. It is not pretty.
- Sidney Burns of Mob Ties.
- 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.
- 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).
- 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.
- 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.
- In Yandere High School, the gym teacher, Rowan, is a SWAT person. His wife, Okami, the main teacher is also on the team.
- 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 Crowning 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.
- 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.
- Some of the teachers from Recess in Recess: School's Out.
- Of the four named faculty, two 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.
- 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."
- The core of the Order of the White Lotus from Avatar: The Last Airbender 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 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 gives us 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 to Eleven 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.
- Xavier, Wolverine, and Storm in X-Men: Evolution, along with Hank McCoy who was pretty tough before mutating into a blue, furry form.
- The title character of Cybersix, who's a literature teacher by day and a superhero by night. There's also her love interest, the Badass Normal biology teacher Lucas.
- Principle Seymour Skinner from The Simpsons. While more of a Retired Badass 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.
- Case in point, beating up the blue haired lawyer and two hired goons after being threatened with a lawsuit over just a trivial copyright.
- The Gromble from Aaahh!!! Real Monsters. He is a Sadist Teacher, but he'll also rain fiery vengance upon anyone who dares threaten his students.
- Ms. Frizzle from The Magic School Bus. C'mon, who wouldn't want to go one of her field-trips? (Besides Arnold, of course).
- Brian Lewis, who for most of his screen time delves into Moral Myopia as an Apathetic Teacher on American Dad!, shattered a hot pot of coffee in Steve Smith's face when he learned Steve had just punched a very young exchange student everybody liked with absolutely no provocation.
- In the Code Lyoko episode "False Start", Jim becomes one, fighting Xana's monsters at Kadac while the regular cast battles the villain on Lyoko.
- Star Wars: The Clone Wars Anakin is this to Ahsoka. Pretty much every other Jedi with a Padawan counts as well.
- Master Hamma from Johnny Bravo.
- Extreme Ghostbusters: Professor Egon Spengler. Invented a portable nuclear accelerator; punched out Cthulhu and other, similar deities; led a one-man charge against an ancient demon called Achira...and mentored a new generation of Ghostbusters.
- 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.
- 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. 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. Although, despite the fact all of them should be considered heroes who made the ultimate sacrifice, in all honesty Librescu still is the most Badass Teacher - he held the armed and physically healthy Cho off long enough for all but one of his students to escape, being 77 years old.
- There is the Troops to Teachers program; former military members get certified to teach, then go to (generally dangerous) schools.
- Joshua Lawrence Chamberlain. A university professor, he took a sabbatical to fight for the Union in the American Civil War, saved the whole Union army with a bayonet charge, was wounded a half-a-dozen times, won the Congressional Medal of Honor, became a Brigadier General (after he was given a few hours to live; he got better) and returned after the war to become head of the school and teach every subject except Mathematics. He was also the officer chosen to accept Lee's surrender at Appomattox Court House and where he served four terms as Governor of Maine.
- 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 doubles as this and Badass Preacher.
- 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.
