Aaahh!!! Real Monsters had The Gromble act this way towards his students (especially if they were being bullied for something they didn't deserve) and genuinely seems to care about their education and is willing to implement 'tough love' if he thinks their ego needs to be knocked down a peg or two. Though when push comes to shove you can guarantee that If anyone dares try to harm or endanger his students he'll be there to defend them. As he demonstrated when he punished a parasite who invaded Oblina's body, defended Ickis to the other students when his spontaneous combustion made him into a social pariah and where he berated a scientist who called his top student, Oblina a 'subject' instead of his 'student.'
Also Slickis deserves mention as he saved his son, Ickis' life at the risk of his own against a giant tank.
In the Adventure Time episode "Simon and Marcy", Simon went to extra-ordinary lengths to protect young Marceline even when she had a cold by trying to find some Chicken Soup. He was determined to protect her (at the cost of worsening his already unstable mental condition) by putting on the crown and using his powers to freeze the threats (or in one case knock out a mutant with his crown and another with a pillow). Needless to say it's not a good idea to harm Marcy when she's with Simon, because as demonstrated in the episode he would do anything to protect her.
Aladdin: The Series: Despite the Sultan being bumbling and childish, mess with his daughter and he WILL come after you. When she is kidnapped by Amazon like warriors, he insists on going after them despite Aladdin's protests and he defeats them.
American Dad! also does this. "Surro-Gate" is a good example, as it shows a Camp Gay who previously solved fights with dance moves out of West Side Story punching out Stan in one hit after he kidnaps the guy's daughter.
Stan: That's not campy. That's not campy at all.
Stan despite his Jerkass tendencies certainly has traits of this with his children as well, should we ever forget what he did to his own boss for insulting Hayley.
In American Dragon: Jake Long the dragon trait skipped a generation, so Jake's mother can't protect him from the supernatural threats he encounters — instead it's Jake's grandfather who does so. Never mind that he even stands up to the Dark Dragon's minions when his entire family is threatened... and obliterates them single-handedly.
Jake's dad OTOH, despite being an ordinary human, gets a couple good moments. He manages to save his son from the Jersey Devil during a camping trip, and later saves him again from a bunch of vampires (who were under the guise of important businessmen).
Archer: So here's the thing, Farooq. I don't know about any stories, but whatever badass shit that you heard I did? You really need some context, because pretty much my whole life, pretty much right up until this minute, my default setting has been half-assed. (cracks knuckles) But that was before I had a child. A child you threatened to harm. A child, I just realized, who's probably on her way up to the roof so Aunt Pam can swat at biplanes! So imagine, as I literally beat you to death - Hang onů Yeah, literally - that a giant hand has turned my dial from half-assed to quadruple-assed!
Hakoda also has some signs of this. Even though Katara is a very powerful Waterbender and Sokka becomes a great warrior, he will stay behind and be captured by the Fire Nation in order to let them escape. There is also his reaction to Katara's announcement that someone was threatening Kya in "The Southern Raiders." When he hears his wife is in danger, it is obvious that if that Fire Nation sailor doesn't haul his ass out of there double time, he will find out just why the Water Tribe hasn't been overthrown yet.
YMMV on that particular scene, as we don't see much of a reaction. Everything else between Hakoda and his kids certainly suggest he counts.
Fire Lord Azulon could be seen as a much darker version of this to his older son, Iroh. When his younger son Ozai tries to usurp Iroh's right in succession, Azulon is so enraged he orders Ozai's innocent son Zuko be executed to teach Ozai a lesson. Fortunately, Zuko had a Mama Bear of his own to prevent this.
Even Avatar Roku is shown looking out for a certain troubled great-grandson of his. At the Fire Temple, Aang channels his spirit to pwn the evil Fire Sages, Zhao, and his soldiers... and then Roku melts the chains holding the good guys and Zuko, letting them all escape before he destroys the temple.
Tenzin in the Sequel SeriesThe Legend of Korra is definitely this. In the season finale, Amon threatens to take away his children's bending. When Tenzin gets loose, he sends Amon flying off the stage.
Tonraq is this as well, especially towards Zaheer who has nearly killed him and his daughter on a few occasions
Ant-Man II from The Avengers: Earth's Mightiest Heroes! mainly uses his powers and abilities to ensure the safety and well-being of his young daughter. In the episode in which he officially became the new Ant-Man, he punished Crossfire for kidnapping her by kicking him in the face, then covering him in ants.
Though they have their issues, Odin still looks after Thor, his son. In The Ballad of Beta Ray Bill, when Bill takes Thor's hammer he is summoned to Asgard by Odin who meant to summon Thor back. This angers Odin who becomes worried Bill may have hurt Thor, to which he delivers this bone chilling statement: "If you have harmed my son, you will pay with your life." Keep in mind this is the All-Father, the most powerful Asgardian.
Batman: The Animated Series: Again, Batman's one principle is to never take a life, but if you dare to enslave innocent children to steal for you like The Sewer King did, you better damn well pray that he does hold onto it.
Batman: I don't pass sentence. That's for the courts. But this time, this time, I am sorely tempted to do the job myself.
In "Over The Edge", we see justhowfar Commander Gordon will go out for Batman if Barbara is ever killed in the line of bat-duty.
Harley's Holiday has General Vreeland. Upon learning that his daughter Veronica has been accidentally kidnapped by Harley Quinn, his first instinct is to demand SWAT Team deployment from Gordon. His second instinct? To commandeer a tank and rescue Veronica himself.
Batman's reaction in the infamous flashback in Batman Beyond: Return of the Joker... when he was beating the heck out of The Joker after the latter revealed that, he not only kidnapped, but subjected Tim-Drake!Robin to three weeks of electrocution-based torture as well as truth serum, and then turned him into a grotesque miniature version of the Joker. He even states "I'll break you in two!" in a very chilling manner.
At this point though, the Joker is so desensitized to Batman's menacing threats that he isn't intimidated even in the slightest. (It's not until the 2nd Batman calls the Joker out on being a pathetic loser with an absurd fixation on the original Batman that Joker starts getting upset).
The cartoon version of Beetlejuice is typically an easy-going prankster whose main interest is driving the rest of the Neitherworld crazy. But on those rare occasions when Lydia is in serious danger, Beetlejuice will show just how he got the title of Ghost With The Most. Insulting or humiliating Lydia is also a bad idea, as Claire Brewster found out the hard way on more than one occasion.
Ben 10 may be well able to protect himself thanks to the Omnitrix, but on one occasion, his father ended up attacking a High Breed with a BFG for threatening him. Considering how powerful the High Breed had been up to that point, doing that is pretty dang impressive. Ben's grandpa Max has also shown traits of this.
And Ben grows up into one in at least one timeline. Kevin 11,000 hurts Ben's son Ken. Cue Ben going Way Big and pummeling Kevin into the ground in an Unstoppable Rage.
Rath, the badass Crazy AwesomeLarge Ham extraordinaire became this in his debut. After warming up to a Triffin Prince that's supposed to help end a war, he finds out that the prince ends the war by being eaten. Rath didn't take this kindly ("Eating babies is NOT! COOL!")—he jumped into the mouth of the alien who ate the prince and came back out the same way, threatening to knit a sweater out of the alien's organs should he declare war. It worked.
Archer season 6 sees Sterling Archer himself become one of these.
Captain Planet and the Planeteers: Yes, the eco-villains, by all means, try to kill the five kids who are more or less the adopted children of an immortal Earth spirit. Granted, it's implied that Captain Planet can't kill, but if you dare mess with his Planeteers, you'd better RUN when he shows up.
In Code Lyoko, while his ability to actually make offensive moves was very limited, Franz Hopper tried his hardest to protect Aelita to the best of his ability. In fact, that was a key part of XANA's plan through much of the fourth season; he directed William to capture Aelita and hurl her into the Digital Sea because he knew Hopper would rescue his daughter, forcing him to reveal himself and leave him open to an ambush by XANA's forces.
PE teacher Jim has even less tools at his disposal but he's incredibly protective of his students and was heartbroken when his attempts to find out what the core cast was up to landed Jeremie in a hospital bed.
Darkwing Duck, whose Tomboy daughter Gosalyn has a habit of getting into trouble like making a Deal with the Devil or releasing an evil trickster spirit. He even finds himself unable to leave the Mirror Universe without merging the two because he can't help thinking of Gosalyn's counterpart as his own daughter. And yes, he has worried about his enemies using her to get to him. In general, threatening Gosalyn is an easy way to make him quickly get over his ego and kick your ass five ways at once.
The only thing Scrooge McDuck loves more than money are his three little Nephews: Huey, Duey and Louie. If you thought he is a dangerous Badass Grandpa when he is pursuing treasure, whoa boy you have not seen how terrifying he can be if you hurt one feather on their heads. Well, there had to be a reason that Donald entrusted them to Scrooge... this is that reason.
Launchpad may be a ditz, but he will put his own life on the line rather than let anyone harm the kids, and given his reasonable competence as a fighter (and the fact that it's a Disney story), it won't be him who gets the worst of it if a villain chooses to test that determination), as demonstrated in "Where No Duck Has Gone Before"note saving the boys from hostile aliens and "Hero for Hire"note facing down the Beagle Boys to rescue Doofus. Bottom line, don't mess with the nephews or Doofus Drake.
DuckTales (2017) showcases Donald Duck as firmly within this trope, as well as the Overprotective Dad trope. Threatening the triplets' well-being is the absolute quickest way to turn him into a One Duck Army aimed squared at you. And he is more than comfortable risking his own well-being if it means they stay safe. The premiere episode showcases him using a metal shield and his bare hands to hold back numerous fire traps to protect Dewey from death.
Even Peter Griffin on Family Guy is capable of this now and then (even if the rest of the time he is an outright Abusive Parent). An episode centered around him becoming more protective of Meg after she almost drowned in a flood, even going so far as to smash stuck-up Connie d'Amico's face into a glass surface until it was a bloody pulp for making fun of her. In another episode, Stewie gets nabbed by Disney World employees who force him to sing for the customers, and Peter manages to save him and outrun a dangerous security guard. Stewie even hugs him for it at the end.
And in the episode when Meg dates Quagmire, he gets really suspicious and angrily asks Quagmire if he slept with Meg.
And when Elisa was shot in her apartment (accidentally by Broadway), Goliath tore through the city to get the gangster he believed did this. When he did find the gangster Tony Dracon, he was willing to kill the guy right then and there for what he (supposedly) did to Elisa.
Agent Six in Generator Rex is this to Rex. Heck, just watch him in "What Lies Beneath" or his fight with White Knight.
Primarily inverted in Godzilla: The Series, where Godzilla, Jr. will go to crazy lengths to protect his adopted father Nick Tatopoulos.
But also played straight with Nick. If you are human and you do something that harms Godzilla, Jr., Nick will end you.
Grunkle Stan from Gravity Falls is an Ambiguously Evil old skinflint and con artist, but there's no doubt he cares for his great-nephew and great-niece enough to take on a horde of zombies with a baseball bat and a pair of brass knuckles. And even more enough to pull a temporary Heroic Sacrifice by trapping Bill Cipher inside his mind while Ford uses the mind eraser gun to erase Stan's mind (thus destroying Bill in the process), and ultimately destroys Bill by punching him and causing him to shatter.
Stan: "Hey, look at me. Turn around and look at me you one-eyed demon! You're a real wise guy but you made one fatal mistake, you messed with my family."
Most evident example in Ice Age is the event when Manny and Diego are defending from Guanlongs Ellie giving birth to her daughter in the third movie.
To drive that point even further, the villain was his own brother, Orm. And Aquaman didn't give a single thought about kicking his ass and letting him die.
King of the Hill: Hank Hill. Whether it's a Jerkass boss putting Bobby in danger at his job, or a Jerkass football coach abusing Bobby and his teammates after losing, they quickly learn the hard way just how dangerous an angry Hank can be. One would think they'd know not to mess with someone who's so into propane. And propane accessories. (Otherwise, though, Hank is something of a "Well Done, Son!" Guy.)
Thug:"I thought that old guy inside was your daddy." Bobby:"No, no! This is my daddy! This one right here, the one with the golf club!"
Dale, too, even after learning that Joseph is "part-alien."
To elaborate on Dale, he once heard his son screaming in his sleep. What does he do? He kicks the door to his bedroom open, brandishing two pistols, ready to blast the threat to kingdom come. When Joseph says he just had a bad dream, Dale says, "Oh. How about I read you a story?"
Sylvester himself gets the chance to be a Papa Wolf when a drunken stork accidentally delivers him a baby mouse. Sylvester initially wants to eat it, but his heart melts when the little thing calls him "Daddy"; he spends the rest of the cartoon protecting his rodent son from other cats, with dynamite if necessary.
Charles Ofdensen, the band manager in Metalocalypse, is seen by some fans to be the Papa Wolf of metal band Dethklok. He is extremely protective, preparing and executing elaborate security measures and counter attacks for their concert in the first season finale; going against assassins twice his size in hand-to-hand combat; having Rockzo the clown beaten and tortured on two occasions for being a bad influence on the youngest member of the band; and warning another manager attempting to take over his position that he would have to kill him to keep him away from the band. And then killing that man himself.In a swordfight.
In Polish animated series Miedzy Nami Bocianami (Between Us Storks), storks can drive away even a wolf (the only one in the forest), for example Czarny (Black (stork)) defending children of his friends. If you compare with Ice Age, you realize that in modern times, when big carnivores are eradicated, storks are relatively safe, like once mammoths.
Mike Chilton acts as this towards his True Companions, the Burners in Motorcity. First noticable in "The Duke of Detroit" episode.
Mr. Bogus, of all people, actually shows shades of this, in regards to watching over his younger cousin, Brattus. If you even dare to pester or threaten Brattus, then may God have mercy on your soul!
Max LeBlanc of Night Hood may have a very bad habit of getting into trouble. But if you try to so much as hurt one hair on his head, count on Lupin and/or Grognard to come to his rescue...and you'll be sorry indeed.
Lord Garmadon from Ninjago may be a full-blown megalomaniac but his one redeeming feature is that he cares dearly for his loved ones. He ends up allying with the ninja... to save his son Lloyd. This trait also carries over even after he's redeemed; he chooses to break his vow of being a non-combantant when Lloyd gets kidnapped by the Overlord.
Dr. Doofenshmirtz of Phineas and Ferb may be an incompetent villain, but don't even try to hit on his underage daughter unless you want to quickly be teleported to another, monster-filled dimension.
Perry the Platypus, especially when it comes to Phineas and Ferb. There was one time when Friendly Enemy Doofenshmirtz indirectly threatened Phineas and Ferb with his latest scheme, Perry quickly beat him up, handcuffed him, and called for backup all within ten seconds.
Happens again in the movie Across the Second Dimension. Perry didn't break his masquerade even when a robot punched him across the room. But when the robot was ordered to do the same thing to Phineas and Ferb, he immediately jumped up and punched the robot just as hard.
God help you if you try and kill Perry when Doofenshmirtz is around (and vice versa) for he will go nuts at you; he is the only one allowed to kill Perry. Likewise, for Perry, he is the only enemy Doofenshmirtz is allowed to have. Got that Peter the Panda?
You do not want to mess with Morty from Rick and Morty while Rick is around. He doesn't often show it, but every now and again it's clear just how protective he is. The most prominent example is probably in "Meeseeks and Destroy," when Rick comes back through the portal and kills Mr. Jelly Bean, who had tried to rape Morty in the tavern earlier.
You can also see it in "M. Night Shaym-Aliens!" when Rick is explaining what's going on.
Rick: These Zigerions are always trying to scam me out of my secrets. But they made a big mistake this time, Morty. They dragged you into this. Now they're gonna pay.
Randy and the other dads sometimes do this, though they're so stupid it doesn't really work out very well. One time it did, however, was when Randy joined Cartman in running a giant drill through the crowd of hippies to get Stan out.
And the season 15 finale has Kenny, as Mysterion, defending his little sister Karen from a bully at the school they went to when their parents got arrested.
Spongebob Squarepants:Spongebob of all people has this for his pet snail Gary. He's only stood up to his boss Mr. Krabs on a few occasions, one of which involved him not being himself at the time and two others being him being pushed over the edge by a great deal of abuse the entire episode. However, on one occasion, Krabs used Gary to steal money for him thanks to him somehow being a living change magnet, something that Spongebob had already told Krabs hurts Gary. When Spongebob finds out, he instantly chews Krabs out for it without a second thought. On another occasion, Spongebob became the adopted father of a bunch of baby worms and this part of him awakened once again. He tackled Larry (the strongest guy in town) when he tried to eat them, then disabled a truck by tearing the engine block out of it with his bare hands to stop it from running over them. Also manages an inversion in one episode when his criminal cousin Blackjack apparently kidnapped his parents, overcoming his crippling childhood fear of Blackjack to confront him. Turns out he hadn't kidnapped them but it still counts.
Octus / Newton is this to Lance and Ilana in Sym-Bionic Titan. Bonus points in that he pretends to be their father when they're at home.
The penultimate episode of season 3 shows how much Obi-Wan has become this for Luke; when Darth Maul gets too close to realizing the true reason why Obi-Wan has taken up residence on Tatooine (he deduces that someone is being protected by Kenobi, even if Maul doesn't learn who exactly that is), the Jedi master only needs three movements to cut Maul down.
In Superman: The Animated Series, where Brainiac is responsible for Jor-El's warnings about Krypton's imminent destruction being ignored, both Jor-El and his father-in-law Sul-Van (the one member of the Council he is able to convince) become this, as Brainiac tries to use the police to prevent him from activating Kal-El's rocket. Mostly Sul-Van, however, who leads the police on a high-speed chase ending in a crash simply to draw them away from the lab and buy his son-in-law time. Knowing that he really has nothing to lose now. In fact, when he's finally caught, just as Kal-El's rocket lifts off, what he says kind of sums it up as a violent quake hits:
Police Officer: Not another one!
Sul-Van: No... The last one...
Antauri from Super Robot Monkey Team Hyperforce Go!. Being the Team Dad, he is naturally protective towards the entire Hyperforce, so messing with them while he's around would be a very unwise thing to do. Especially when it comes to Chiro. Heaven help you if you hurt Chiro.
TaleSpin:God help you if you screw with Kit. If Parental Substitute Baloo doesn't punch your lights out, he'll chase you down with his plane.
Though obviously not shown to the same extent as Rebecca, Baloo has traits of this around Molly as well (likely to further emphasize his chemistry with the former). Whether she's been kidnapped by bandits, zapped by a microscopic ray, or just wants her Christmas wish to come true, Baloo is pretty insistent she come out of it all with a smile on her face.
In the Teen Titans episode "Betrothed," Galfore, Starfire's k'norfka (guardian) is introduced, a huge, hulking, muscular guy who is willing to use violence if someone does anything that even might be a threat towards his ward. (Oddly enough, this is one thing that Beast Boy learns rather quickly.)
Being this protective to one's ward may be a common trait for a k'norfka, actually. Starfire herself becomes a Mama Bear towards Silkie after she gives herself this title towards him.
Teenage Mutant Ninja Turtles: Master Splinter made sure that his adopted sons could take care of themselves, but if you happen to be planning on experimenting on them, you'd better pray he doesn't find out.
The 2003 series might be the strongest example, as circumstances caused Splinter to be in combat situations a fair bit in that series. Fair bit of advice to that continuity: If you're beating on, or even just FIGHTING, the Turtles and you hear a gravelly voice growl "MY SONS!," just give up now. It'll be less painful for you.
Two examples on the heroes' side in The Amazing Spiez. Cal Clark, the main team's biological dad and Jerry (carrying over from Totally Spies!). Messing with any of the Clark kids when either of these men could find out is a bad idea.
In The Fairly Oddparents, even a ManchildBumbling Dad like Mr. Turner is capable of fighting with teeth and paws to defend Timmy. Just watch the episode where Timmy wishes he could merge with dad's Cool Car, then Vicky steals the car, and he believes Timmy is stuck in it...
Both of Timmy's parents, despite being comically irresponsible enough to leave him with an evil babysitter, have gone to crazy lengths to protect Timmy. This came to the fore when Timmy wishes they had superpowers, and he ends up using this to his advantage when convincing them to give up their powers.
Don't forget the end of the Fairly Oddparents movie, where Papa Wolf dad and Mama Bear... Mom double-team Mr. Crocker for abusing their son. Much ass kicking ensues.
Actually, Mr. Turner technically could be counted as a literal "Papa Bear" at that point.
Private of The Penguins of Madagascar has shown this. When the penguins are tasked with taking care of an egg in shifts, Private is so horrified by the other penguins' rough handling that he steals the egg away and snaps at Skipper.
The Powerpuff Girls usually don't need Professor Utonium to protect them, but the rare times they do, he definitely qualifies. (Or at least he tries.)
One episode where Utonium tried to join them on their adventures, embarrassing them to no end, is resolved by them exploiting this; they let Mojo Jojo kidnap them and let Professor Utonium fight him one-on-one to save them, knowing he'll tire himself out and call it quits.
When Egon of The Real Ghostbusters was literally paralyzed with fear by the Boogey Man, he found the strength to escape his bonds when the Boogey Men threatened the Junior Ghost Busters, a trio of children he had been mentoring.
The Ren & Stimpy Show: In "A Visit to Anthony," Ren and Stimpy are severely intimidated by Anthony's father. And they have every reason to be. He's very large, heavily muscled, despite his age, and unlike most of the "lummoxes" seen in the show, he is not only healthy looking, but reasonably intelligent. Just getting a threatening speech from him puts the fear of god into you. His silent rage is even more frightening when coupled with his weeping when he thinks his son is in danger, even if it's just of being disappointed.
The Simpsons: Homer Simpson may be the personification of the Bumbling Dad, but once he gets it through his thick skull that something's wrong with his kids, he will move mountains to make it right. One example is when Bart is being conned of his share of profits and the conman won't budge.
Homer: Alright, this is a homemade class 2 nuclear reactor. If I turn up the power this would create an explosion that could wipe the whole metropolitan area.
The Smurfs: You don't threaten Papa Smurf's little Smurfs unless you want to be on the receiving end of one of Papa Smurf's potions.
Grouchy towards Baby Smurf. If Baby Smurf's introductory episode wasn't any indication, in one episode it was revealed that Grouchy couldn't swim, followed by the other Smurfs trying unsuccessfully to teach him. But the moment Grouchy saw Baby in trouble, all fears left him and he immediately dived into the water to rescue him.
Brock Samson is the Alpha Papa Wolf whenever someone threatens the Venture family. See Victor. Echo. November. for the naked, murderous evidence.
Dr. Orpheus as well to his own daughter and towards the Venture boys.
In this scene (a direct parody of the one in Taken) the RedDeath is able to accomplish more with words than Liam Neeson's character could ever hope to.
The Zeta Project shows us the DCAU is filled with these. Agent Bennett, the closest thing the series has to a villain, a man who has dropped everything to chase a criminal across the country, promptly drops everything to save his son. He even works with said criminal to get his son back and spends time with him afterwards rather than go back to work. He's very dedicated to the NSA, but touch his kids and he just doesn't give a crap about them.
Buck Tuddrussel in Time Squad. While known to be a complete Jerkass at the worst of times, and often lets Otto get hurt through blind negligence; Tuddrussel will kick some major ass if Otto is in mortal danger and the thought of losing him to someone else makes him just as pissed. Same goes for the campy robot partner Larry, which crosses into Mama Bear territory.
Tom and Jerry: We all know Jerry Mouse is no push-over in regards to Tom Cat. But if Tom ever lays a paw on Nibbles / Tuffy, the local Heartwarming Orphan and Jerry's adoptive pup, he's in for even more of a pain in the tail than usual. Nibbles / Tuffy's introductory episode leaves the deal very clear; Tom spanks the little mouse and, after releasing himself from a trap and checking on the other's well-being, Jerry lets out an enraged lion's roar and brutally beats up Tom.
You also don't mess with the local neighborhood bulldog Spike's son, Tyke, in any fashion, though that really should be obvious.
Ratchet from Transformers Animated doesn't like to hear his friend Omega Supreme, who he mentored during the war, being threatened. Of course, Omega is a Person of Mass Destruction built to end the Great War, so this doesn't happen often, but...
Ratchet (to the Autobot High Council): Omega Supreme is one of us. An Autobot. A friend. Harm one circuit on him and you'll answer to me.
It should be mentioned for the un-initiated, that Ratchet is both an old man and a medic, with no offensively designed equipment. Yet you still don't doubt that he could very well hand them their asses on a plate if pressed.
Somewhat off-screen in Winx Club and crossing with Mama Bear is Oritel (Bloom's Dad). After both he and his wife think both their daughters to be dead, they according to one account went completely berserk at the ones responsible; the Ancestral Witches. Considering how high they are in among other's Faragonda's and even Valtor's regard, that says something about the power which was unleashed. Ouch. When Oritel has returned by Magical Adventure, he is fiercely protective of Bloom, banishes Sky from Domino when he thinks Sky has dumped Bloom, and doesn't hesitate to fight the Trix and Ancestral Witches when they threaten Bloom.
To explain what happened in that movie: when the Trix attacked the Winx he jumped out of nowhere and, after promising the Ancient Witches he'd make them pay for killing his older daughter, proceeded to kick the Trix' asses single-handly in spite of having no magical power and his sword having been depowered alongside all the fairies; and when the fairies and his sword recovered their power the Ancient Witches possessed Trix (who were easily defeating Bloom and the Winx Club) could barely cringe in fear when they saw him charge before he turned the side of the battle (it was the Winx to wipe out the Ancient Witches for good, but they would have lost without Oritel kicking their ass while they prepared the spell). It's also stated in both movies that it was Oritel and his wife Marion to destroy the Ancient Witches Coven one by one in revenge for the apparent deaths of both their daughters, with the Company of Light being there mainly to cover their backs and finish stragglers, and when they were finished the Three Ancient Witches were weak and bodyless, most of the coven had been wiped out, and of the two survivors Mandragora had been imprisoned with the Ancient Witches, and Valtor (the Big Bad of Season 3, with the power to defeat the rest of the Company of Light alone) had been left barely alive and survived only because they were in a hurry to finish the Ancient Witches.
Young Justice: Black Manta towards his son Aqualad, despite almost killing him in Season 1, in Season 2 he responds to Sportsmaster's request to kill him with an angry: "No one touches my son." After that, he tries to have Psimon, and later Miss Martian help him. When Sportsmaster and Cheshire attack his sub, he orders his men to help his son instead of him, and later abandons his fight to save him. In addition, when his men set a charge to blow through a door and rescue him, he detonates it prematurely, blowing the soldiers away, wanting to get to his son as soon as possible.
