Kitty: I did.
Boss: And who are you?
Kitty: I'm his mother.
Boss: Okay then.
- Chi-Chi, and later Bulma (pictured above), from Dragon Ball Z. Chi-Chi's vicious telling off of anyone who mistreats or endangers her children had been a long Running Gag in the series, until she tried to do it to Majin Buu, at which point it stopped being funny.
- Invoked in the episode "Odd One Out" in Halo Legends. Two of the colonists on the planet claim "No one is stronger than Mama" as they and Spartan 1337 are about to face off against the Covenant warrior. At the end of the fight scene, the wreckage of the UNSC Frigate, which up to this point was just a background object, lights up and fires the Covenant into a Slipspace rupture. Mama was the frigate's AI.
Sesshoumaru's Mother: Did you think you were like a god or something? That as long as you had Tenseiga there was no fear of death? Sesshoumaru, it's something you had to learn, that when your heart wishes to save someone dear to you it must at the same time feel sadness and fear of losing them. Your father said this as well: Tenseiga is a healing sword. Even when wielded as a weapon, you must understand the weight of life and carry a compassionate heart when dispatching your enemy. That is what is necessary for the one who wields the Tenseiga which can save a hundred lives and send enemies to the Meidou.
- Sesshoumaru is a young Youkai, so powerful and wilful that his father's allies fear him and even Naraku plots carefully before crossing paths with him. His obsession with obtaining his younger brother's sword is such a problem that it can't be resolved until after direct intervention from his mother. Her ability to put her wayward son in his place is brutal. It's terrifying. It works.
- Pokémon's Delia Ketchum gets to be this in the third movie, Pokemon 3: Spell of the Unown, when she stands up to Entei. It was a failed effort, but she gets points for trying.
- Miyako Sakuragawa's mother, Kyouko, from Private Prince. Runs the family ryokan firmly, is both loved and feared by everyone in it (her husband and daughter included), and does not tolerate anyone stepping out of line.
- Anna Kyouyama, later Asakura from Shaman King became one of this in Shaman King Flowers. Her reputation as the only person able to master Hao's tecniques makes her son's enemies plot things carefully before messing with him. Heck, this woman can talk back to Hao, God himself, and threat him to revive Hana's little baby body and he complies at the first threat.
- Ragyo Kiryuin from Kill la Kill is a stellar example. No matter how powerful and charismatic her daughter Satsuki is, Ragyo is always a full tier above her, overstripping her in both power and authority, the former of which she displays consistently through the latter part of the series. Even when Satsuki rebelled and Ryuko was revealed to be her daughter as well, she has absolutely no problem putting everyone including both her daughters back in their place. The downside is, she's also the villain. And a horrible mother.
- In Captain Tsubasa, Ryo Ishizaki is terrified of his mother. Mrs. Ishizaki turns out to be one of these: harsh, Hot-Blooded like her son, very strong-willed, and not afraid of speaking her mind at all. Though if you're on her good side, she's a total sweetheart.
- In the first Card Captor Sakura movie, Syaoran is also pretty scared of his mother Li Yielan, and even his super bubbly and energetic four older sisters settle down when they're around her, implying that she is this trope.
- This trope could be named The Aunt May, because she is often this trope:
- Aunt May does this to Tony Stark and Reed Richards in Spider-Man: The Other, when they want Peter to take more tests instead of going out with Mary Jane. The two most brilliant men in the Marvel Universe are no match for Aunt May's stern reprimand.
- Aunt May also does it to J. Jonah Jameson over the phone in an early episode of The Spectacular Spider-Man, when JJJ yells at Peter for being late.
- When the Parker family moved in to the Avengers' tower, Aunt May scolded Wolverine for drinking and smoking so early in the morning in the breakfast room. Wolverine is stunned into silence.
- Aunt May also slagged off JJJ in #616 after she found out Peter was Spidey; she couldn't stand JJJ badmouthing her nephew in the Bugle, even if she couldn't tell JJJ why she was pissed at him for badmouthing Spidey.
- Aunt May told off the Scorpion for being impolite. "I don't much care for that awful Spider-Man, but at least he is polite!" Complete with finger-waggle.
- Ultimate Aunt May is just as almighty. After JJJ unfairly fired Peter, Peter calls her to ask if she can come pick him up and she ends up yelling Jameson's ear off when she finds out he fired Peter. Then she insults his mustache. Jameson calls Peter back and tells him he can have his job back under the condition that he never has to talk to Aunt May again.
- Ultimate Aunt May takes it a step further post-Ultimatum when she not only takes in Johnny Storm and Bobby Drake (in addition to Gwen Stacy who'd been living with the Parkers for a while), she gets them into Peter's school and sets a moratorium on super-heroing unless she gives the boys permission.
- Rare male example: Batman's Alfred Pennyworth.
- Bianca Reyes from Blue Beetle. She told off her son for getting into a fight with Green Lantern Guy Gardner, and then followed it up by yelling at Guy.
Bianca: Is. That. A Giant. Green. Fist?
- Which promptly leads to her husband admitting to Jaime's best friends that she is the reason he never has to raise his voice.
- In the Ranma ˝ fanfic Cheaper by the Dozen Ryoga runs across Ranma twenty years later and is horrified to discover that his former rival has become an almighty mom after a trip to Jusenkyo gone disastrously wrong forced her to spend the next twenty years giving birth to 24 copies of herself.
"Damn it, Ranma may be a mother, but she wasn't HIS mother. So how did she manage to make him feel like a little kid?"
- Queen Elinor in Brave. She can stop a Ballroom Blitz between three feuding clans (and her husband) of Violent Glaswegians simply by walking through it in a calm, regal manner. All the brawling Scots will immediately stop and bow, moving only to let her pass. She then calmly walks back to her throne while holding her husband (the king), as well as the three leaders of the clans, by the ear, who doesn't even try to resist. Merida, though, has a... low opinion of her mother, believing her to be just My Beloved Smother until the Queen is transformed into a bear (and that's kiiiiinda Merida's fault) and ends up defending her daughter against a demon bear.
- The main character's mother in Almost Famous does this to the rock band that's touring with him.
- Fargo: Margie Gunderson is an Almighty Mom in the making - just witness her telling off multiple-murderer and Grimsrud after shooting him in the leg and taking him in single-handed.
"There's more to life than a little money, you know. Don'tcha know that? And here ya are, and it's a beautiful day. Well. I just don't understand it."
- Cordelia Naismith Vorkosigan. She even tells off the parents of other children. In less than five minutes. By telling them to sit on a sofa.
- This is one of the main character's "powers" in the novel Confessions of Super-Mom.
- In Robert A. Heinlein's The Cat Who Walks Through Walls, the Moderator [Mayor] of Hong Kong Luna has our hero, Richard, under arrest when "Auntie" Washington arrives and makes them all kids who have gathered to praise Richard for his heroism. Naturally, they let Richard go rather than mess with Auntie.
- Mrs. Molly Prewett-Weasley to everyone in the Harry Potter series, except Harry whom she almost never criticizes. She's especially hard on her own children, but the members of the Order of the Phoenix know all about her wrath as well. To wit, one of the most famous lines of the series—partially due to the Precision F-Strike and partially due to its awesomeness...
- Molly: Not my daughter, you bitch!
- Charity Carpenter from The Dresden Files. Harry claims her tongue is sharper than the Absurdly Sharp Blade Amorrachius. She turns out to be one badass Mama Bear.
- Nita's mom in the Young Wizards series stops her daughter from making a Deal with the Devil, and tells off the Lone Power.
- Dairene pulled of a similar feat for the species of wizard supercomputers she built on her ordeal.
- Discworld's Sybil Vimes comes from a long line of these. Her aunt is mentioned to have given a pair of highwaymen who attacked her coach such a talking to that they ran home to their own mothers to apologize.
- Adah from The Red Tent. Don't underestimate her just because her health is failing in her old age!
- Kel's mother in the Protector of the Small books by Tamora Pierce. Although the most badass thing she does in the present is yell at Kel's Drill Sergeant Nasty, in a flashback we see her protect her daughter and a bunch of sacred relics by slicing up a gang of pirates.
- People are impaled in The Last Dragon Chronicles, but no one will ever disobey Liz. Think about it.
- Burn Notice has Madeline Westen, whose real skill is the way she can shift effortlessly between soft-power "I'm a sweet little old lady and I know what's best" mumsiness to hard-power "Do what I tell you or there'll be trouble" Mama Bear Mode. In other words, she can play Good Cop/Bad Cop on her own.
- Michael Westen: Mom, put down the shotgun.
- David's mom on Kings did this a couple of times to different people, including once to the King himself.
- Lois in Malcolm in the Middle is this to such a degree that she has a minor Heroic BSOD when faced with a problem that she can't fix by telling people off (a highway accident blocking traffic), or with proof that she's in the wrong (security footage of her making an illegal manoeuvre). Eventually turns out that she was right in the latter case, but Hal and the boys destroy the evidence to avoid giving her the impression that she's always right about everything.
- Mrs. Kim on Gilmore Girls. She arguably terrifies everyone in Stars Hollow.
- The Boss in Metal Gear Solid 3: Snake Eater. She acts as a surrogate mother to Naked Snake, her son is Ocelot, and she is feared and respected and also feared by everyone including Colonel Volgin. At one point, he says he's beginning to question the Boss's loyalty, and her stoic reaction makes him shrink in fear. Later on when Snake is discovered, he and The Boss brawl only to have him lose, and when Volgin is about to shoot Snake in the head, The Boss retorts "You stay out of this!", grabs the gun from Volgin's hand, and beats him. Volgin is over 6 feet tall, heavily muscled, batshit insane and has lightning powers and The Boss slaps him down. She also has a habit of ripping up people's guns while they are still in their hands.
- Macha from Chrono Cross is this for the few moments that she has time to actually display a personality.
- In Suikoden V there's one person Logg and Lun wouldn't cross, it's Kisara.
- In the remake of Tales of Innocence, this is Played for Laughs with resident Team Mom Ange. Once she descends into Tranquil Fury or has rather unsettling smile on her face, not even Ricardo dares to cross her.
- Leia's mom in Tales of Xillia not only taught her her fighting style, but in the sequel, Gaius ends up admitting she's the only person on his list of "people he never wants to end up fighting one day". Considering Gaius was the Big Bad and Final Boss of the first game, this says a lot.
- Zhang Chunhua is known to inspire fear in even enemy troops by her mere presence, let alone among her family, who are too afraid to even ask her for help.
Wang Yuanji: Lady Zhang Chunhua, do you have a moment? It's about Master Zhao...Zhang Chunhua: Is that idiot son of mine causing you grief, Lady Yuanji? I'll be sure to punish him, so please don't give up on him.Wang Yuanji: Oh no, it isn't that bad...Zhang Chunhua: You must not go easy on him. It is vital to take a strong stance from the beginning.Wang Yuanji: ...Y-Yes, my lady.

- On The Fairly Oddparents, Timmy's Mom attempts to do this to the mean Dr. Wendell after he steals Timmy's ball. Eventually she, without losing her motherly tone, decides to slam Dr. Wendell in the face with the ball and steal his perfect dentures instead.
- In the episode "Halloween On Spooner Street" from Family Guy, Lois tells off another mother of a child who stole Stewie's candy.
- In an episode of Rocko's Modern Life, Heffer has sold his soul for a chance to be on a game show, and has to spend eternity in Heck. His grandmother (who he had been told was in Heaven) is down there, and she doesn't want to spend eternity with her grandson, because she doesn't like him. She tells off Peaches, and Heffer is allowed to go home scot-free. Peaches gets in big trouble with his beanie-wearing boss for listening to her, though
- Super Best Friends Forever shows that while Supergirl may be a Kryptonian Flying Brick that could challenge Superman in a fight, she still has to bow down to the authority of Martha "Ma" Kent.
- Superman: The Animated Series: Ma Kent took out Braniac, who has destroyed whole worlds, with a shotgun when he went after Clark.
- My Little Pony: Friendship Is Magic: Fluttershy can act like this towards her animals or monsters when she gets assertive. Her staring down a cockatrice while lecturing it as if she was its mother was an example.
