* In ''Disney/OneHundredAndOneDalmatians'', Pongo [[BattleCouple teams up]] with [[MamaBear Perdy]] to lay the hurting on the two thugs about to kill not only their puppies but all 99 puppies. Their treatment of the bad guys is SCARY. You do not mess with puppies and let their parents find out.
* [[Disney/AladdinAndTheKingOfThieves Cassim is very protective of his son]]. While they have been separated for years, he still risks his life and tries everything in his power to keep Aladdin safe.
* Although not the biological father, O'Malley from ''Disney/TheAristocats'' adores Duchess and her three kittens, and he fights quite ferociously to prevent the BigBad from shipping them to Timbuktu.
* Fish from ''WesternAnimation/TheBoxtrolls''. Despite being a shy, cowardly creature, it's evident Eggs is more important to him than anything - and he proves it, too, even lashing out at his attackers when the boy is harmed. He's knocked out almost immediately, but considering the boxtrolls' nature, it was a brave act.
* Fergus in ''WesternAnimation/{{Brave}}'' is a loving husband and father who would fiercely protect his wife Elinor and their four children from any danger. However, this almost has some serious consequences when he goes after a bear because he thinks the bear has [[spoiler:killed Elinor]] and is now attacking their daughter, Merida. [[spoiler:The bear actually ''is'' Elinor, who has lost control of her bear form and has lapsed into wild behavior, but Fergus is mad with grief and refuses to listen to Merida's (admittedly crazy-sounding) explanation.]]
* ''WesternAnimation/TheCroods'': It doesn't matter if you're a weird cat/owl hybrid thing, and multicolored sabertooth cat or even a new and more civilized cave person. If you threaten Grug's family, indirectly or not, ''he will take you down''.
* Gru from ''WesternAnimation/DespicableMe'' [[TookALevelInBadass takes a level in badass]] after his three adopted daughters [[spoiler:are kidnapped]]. Among other things, he hopscotches over a group of heat-seeking missiles fired towards him and ''one-punches a shark!''
** In a minor case, when the carnival barker denies Agnes the unicorn she wanted, even when she hit the nearly impossible target. He almost makes her cry, and Gru shows him why he should never mess with the adopted children of a supervillain.
* In ''{{WesternAnimation/Epic}}'', Mandrake singlehandedly destroys an entire tree after someone [[spoiler:makes light of his son's death]].
* Marlin in ''WesternAnimation/FindingNemo'', because how many fish do you know would risk life and death across an ocean that is infamous for some of the most POISONOUS and DANGEROUSLY VICIOUS creatures of the sea, to find his son? He's not even a shark, he's a ''clownfish'' who's [[CowardlyLion scared of everything]].
* Mumble from ''WesternAnimation/HappyFeet'' goes beserk if you try to harm his son. If you are a skua who tries to harm his son, he will bash you aside as if you're a bowling pin. Even if your an elephant seal, [[CrowningMomentofAwesome HE!]] [[PunctuatedforEmphasis WILL!]] [[RammingAlwaysWorks RAM YOU!]]
* [[WesternAnimation/HowToTrainYourDragon Hiccup]] is lucky enough to have two of these...one is his biological father, a BadAss Viking who's willing to punch dragons in the face and dent metal with his hammer to protect his boy, and the other is a freaking ''dragon.'' A dragon who attacks and drives off another dragon a little over three times his own size when the other threatens Hiccup.
* ''WesternAnimation/TheIncredibles'', Helen and Bob (a.k.a. Mrs and Mr Incredible) do a [[BattleCouple Mama Bear and Papa Wolf team-up]] when they take on half of Syndrome's men to get to their kids.
** When Syndrome kidnaps Jack Jack at the end of the movie, Bob ''throws a freakin' car at him''.
** The look Bob gives Syndrome when he is told his family is dead sums up this trope.
*** As does the moment when (still thinking they're dead) he [[spoiler:nearly strangles Mirage]], and threatens to break [[spoiler:her]] in ''half''.
* Whether it's Disney's ''Disney/TheJungleBook'' or ''WesternAnimation/TaleSpin'', messing with Mowgli/Kit will get you trouble from Baloo. In the former, he tells the monkeys outright, "Keep your flea pickin' hands offa my cub!" In the latter, discovering that someone has conned Kit leads to a different threat, "Wait until I get through with that guy he'll be able to count his teeth on one finger!" Both Mowgli and Kit even affectionately call him "Papa Bear".
* Tramp from ''Disney/LadyAndTheTramp'' fights and kills a rat in order to protect the infant son of Lady's owners.
** He's also protective of his son Scamp in ''Disney/LadyAndTheTrampIIScampsAdventure'', when he saves him from a large and angry mastiff and snarls "Keep your paws off my boy!"
* ''Disney/TheLionKing'': Mufasa is the best father ever (no matter his species), as he is wise, just, loving, stern when necessary, and royal. But don't you ''dare'' cause ''any'' harm to his kid, or he will ''find'' you and he will ''kick your ass''(unless you're unlucky...).
** [[Awesome/TheLionKing IF YOU EVER COME NEAR MY SON AGAIN...!!!]]
** This is a TruthInTelevision, as the RealLife section of PapaWolf attests.
** Inverted with Simba as he becomes enraged when [[KickTheDog Scar strikes Sarabi]].
* Sulley from ''WesternAnimation/MonstersInc''. Harm Boo, and you'll find out why he's the scariest monster on the floor.
* ''WesternAnimation/MrPeabodyAndSherman'': Mr. Peabody is an almost literal one to Sherman, being a dog and all. [[spoiler: He even bites a bigoted social worker trying to take Sherman away.]]
* In ''Disney/{{Mulan}}'', TheEmperor is this to ImperialChina. The ancestors and the dragons to Mulan's family.
* Spike is a literal example in the ''WesternAnimation/{{Rugrats}}'' films. In the first film, he fended off a wolf that threatened the babies. In the crossover film with ''WesternAnimation/TheWildThornberrys'', he teamed up with Eliza to find the babies.
* Disney/WreckItRalph is a nine foot tall, 643 pound GentleGiant. Harming anyone he cares about, namely Vanellope, will bring out the worst in him.
