History BigBrotherInstinct / WesternAnimation

* ''WesternAnimation/{{Rugrats}}:''

* Most ''Franchise/Transformers'' TV series feature human characters, with said characters usually being kids, teenagers, or young adults. Expect every Autobot in the show (especially Prime and Bumblebee) to drop everything if their human friends need them, or to go out of their way to help them if they can.

* In ''WesternAnimation/FantasticFourWorldsGreatestHeroes'', Susan is this to Johnny. One of the most notable examples is "[[Recap/FantasticFourWorldsGreatestHeroesTrialByFire Trial By Fire]]."

---> Soos: Sorry [[spoiler:Mr. Pines]], but I have a new mission: to protect these kids!

* ''WesternAnimation/TheOwlHouse'' gives us Hunter, who in the later part of season two befriended and developed this towards Gus, and to a lesser extent toward protagonist Luz. A point of interest is that, even in Hunter's villain days, many fans noticed a sibling-like dynamic between Luz and Hunter in the form of petty squabbling and him treating is younger foe like a nuisance("She can ruin someone else's day."), but seeming reluctant to actually hurt her.

** For the X-men franchise as a whole this trope is all over the place. In general, when the students are in danger, the older ones will protect their younger peers and the teachers will all break out their Mamabear or Papawolf sides. Or as Xavier himself puts it...

-->'''Charles Xavier''' I pity the poor, misguided fool who goes to that school seeking trouble.

* WesternAnimation/MyLifeAsATeenageRobot: Jenny has a BigSisterInstinct towards her friend, Tuck. She’s sees him as her little brother and is often protective of him. He likewises sees her as a CoolBigSis

* Comicbook/{{Wolverine}} often acts as a mentor to one of the younger heroines on the team: Kitty Pryde (comics), Jubilee (comics''/''[[WesternAnimation/XMen animated series]]), or Rogue (film''/''[[WesternAnimation/XMenEvolution second animated series]]).

** Female version -- Let it be understood that only Shelley has the right to torture little brother Stan.

** [[BarbarianHero Finn]] is ''fiercely'' protective of his [[LivingEmotionalCrutch adoptive brother Jake]], despite technically being the younger of the two. He’s very easy-going, but if you hurt Jake, [[BerserkButton all bets are off]] – he will unload a can of whoop-ass on anything that touches his brother. Played straighter towards [[ParadoxPerson Fern]], as Finn constantly supports and encourages him, psychs himself up to slay a monster by pretending he's saving Fern, and mercilessly [[spoiler: killing the Grass Entity]] to protect him.

* ''WesternAnimation/MegaMan'': Mega Man is this to his sister Roll to the point that in the pilot episode he is crush by a monorail train protecting her. In the same episode he tells a lie, something that robots are supposedly incapable of doing, to save Roll from reprogramming.

** In [[Recap/MyLittlePonyFriendshipIsMagicS1E5GriffonTheBrushOff Griffon the Brush-Off]], [[GenkiGirl Pinkie Pie]] and [[{{Tomboy}} Rainbow Dash]] have fun pranking [[HoldYourHippogriffs everypony]], but Pinkie has a strong instinct to protect [[ShrinkingViolet Fluttershy]] from even their most harmless prank.

* ''WesternAnimation/TeenTitans'': The Titans have this towards each other. Of additional note is [[BadassBookworm Raven]] having this towards her "kids" (Melvin, Timmy Tantrum, and Teether), [[PluckyComicRelief Beast Boy]] towards his adoptive family (the Doom Patrol), and [[TheLancer Cyborg]] towards the Titans East team.

* ''WesternAnimation/YoungJustice'':

* ''WesternAnimation/{{Arcane}}'': Vi has this for her little sister Powder and their mutual friends. She always makes sure Powder is never in harm's way, [[spoiler:which is why she's wracked with guilt for hitting Powder and blaming the girl for the deaths of Vander and their friends.]]

* ''WesternAnimation/{{Arcane}}'': For Powder and her other friends. She always makes sure Powder is never in harm's way, [[spoiler:which is why she's wracked with guilt for hitting Powder and blaming the girl for the deaths of Vander and their friends.]]

** Sarah herself is this to Jimmy, she maybe is a SpoiledBrat but this is arguably one of her redeeming qualities.
