History Main / BigBrotherMentor

* Tom Paris to Harry Kim in ''Series/StarTrekVoyager''.

* In the anime of ''Manga/{{Planetes}}'', Hakim Ashmead fills this role for Hachimaki, at least until his [[spoiler:HeelFaceTurn when he is revealed to be TheMole for the terrorist Space Defense Front]].

* In ''Manga/MyMonsterSecret'' Ryou initially seems to be this, giving his younger sister Nagisa seemingly profound advice, but it quickly becomes clear that he's just a lazy bum who makes crap up on the spot.

* In the anime of ''Anime/{{Planetes}}'', Hakim Ashmead fills this role for Hachimaki, at least until his [[spoiler:Heel Face Turn where he was revealed to be The Mole for the terrorist Space Defense Front]].

** Ash eventually takes up this role towards May in the ''[[Anime/PokemonTheSeriesRubyAndSapphire Advanced Generation]]'' saga, and towards Dawn in the ''Diamond and Pearl'' saga.

* ''Anime/{{Pokemon}}'':
** Brock is this to Ash and anyone else who is in the main traveling group in the ''{{Anime/Pokemon}}'' anime.
** Ash eventually takes up this role towards May in the ''Advanced Generation'' saga, and towards Dawn in the ''Diamond and Pearl'' saga.
** During the Unova arc, [[spoiler:Charizard]] became this to the rest of Ash's team (Pignite in particular).

* Maiza Avaro to Firo in ''LightNovel/{{Baccano}}''. Firo reminds Maiza of his younger brother and guides him into the Camorra and fittingly enough, [[spoiler:after devouring Szilard, Firo obtains Maiza's brother's memories along with those of Szilard's other victims]].

* As Setsuna's [[SempaiKohai sempai]], Kira in ''Manga/AngelSanctuary'' often acts this way towards him. Yue Katou too to some extent. Sara Mudou calls Setsuna "aniki," but his behavior towards his own sister is more along the lines of BrotherSisterIncest.

* Given that ''VideoGame/EnsembleStars'' is chock full of SempaiKouhai relationships, it naturally has heaps of these, with group leaders in particular usually acting as brotherly mentors to younger members. Nazuna takes it furthest, however, outright requesting that the other members of Ra*bits refer to him as 'oniichan', which they all do happily. (Of course, that might be also his attempt to make it clear that [[OlderThanTheyLook he's two years older than them despite how he looks]], but he certainly fits the role regardless.)

* ''LightNovel/BanishedFromTheHerosParty:'' Red, a.k.a. Gideon, serves as this to his younger sister Ruti and Al, a boy in the village he retires to. At the start, Ruti knew nothing. Nowadays, she is an expert in fighting and information gathering, all of which her brother taught her. She even imagines a HelpfulHallucination of him when she needs to think. Al, meanwhile, is trained both by Rit and Red. While Rit is an expert with Al's weapon of choice, Red also has so much experience that Al is in awe of Red's strength.

* ''Fanfic/HailToTheKingThuktunFlishithy'': ''Series/ZoneFighter'' acts that way towards Shinji. He teaches him to fight and to be more confident, assertive, selfless, and courageous. Through this process, Shinji [[GrewASpine grows a spine]] and becomes a hero.

* ''[[Fanfic/GodsAngelsAndKings Hail To The King]]'': ''Series/ZoneFighter'' acts that way towards Shinji. He teaches him to fight and to be more confident, assertive, selfless, and courageous. Through this process, Shinji [[GrewASpine grows a spine]] and becomes a hero.

* In ''WesternAnimation/BigHero6'', Tadashi is ''literally'' Hiro's big brother, is stated as being responsible for Hiro getting into robotics, gets him out of the bot fights and inspires him to enroll at SFIT, and [[spoiler: dies for the plot]].
* ''WesternAnimation/BrotherBear'': Sitka, who explains to Kenai the significance of their respective totems (guidance and love), and what it means to be a man. The latter bit is elaborated on a bit more in a piece of dialogue that was ultimately cut from the movie:
--> ''"It's not about how fast you can run, or how far you can throw a spear [...] People see you as a man because of what's inside you."''

[[folder:Films--Live-Action]]

** It's played straight with Detective Wataru Date, who took his younger partner [[NamesTheSame Wataru]] Takagi under his wing and called him his little brother. [[spoiler: Sadly, this case ''did'' include the death part.]]

* In the ''Literature/HIVESeries'', benevolent AI [=H.I.V.E.mind=] is this to [[TheHero Otto]]. He guides Otto, normally an InsufferableGenius, to becoming a more tolerable person. He also serves as TheParagon in book three. Once the two begin SharingABody, they actually switch roles, with [=H.I.V.E.mind=] acting grateful towards Otto for showing him [[PinocchioSyndrome what it is like to be human]] and effectively taking the role of the HypercompetentSidekick.

* Seigi says Richard of ''LightNovel/TheCaseFilesOfJewelerRichard'' is like an older brother he never had to him, always giving him advice.

* Albert/004 in ''Manga/{{Cyborg 009}}''. His "little brother" Jet/002 later also has some Big Brother Mentor moments in the Little Psychics mini-arc.

[[folder:Web Comics]]
* Wendy of ''[[Webcomic/CwensQuest Cwen's Quest]]'' is a female version of this trope as well as Cwen's NonHumanSidekick and the good guys' {{Only Sane Man}}. She tends to {{deadpan snark|er}} rather than hit people upside the head when they are doing something stupid due to her small size. [[http://www.drunkduck.com/Cwens_Quest/index.php?p=415926 When hasn't always returned this consideration]]. She avoids being the {{Team Mom}} by only offering her snarky advice to Cwen and letting most other people [[http://www.drunkduck.com/Cwens_Quest/index.php?p=410033 make horrible, horrible mistakes]] or [[http://www.drunkduck.com/Cwens_Quest/index.php?p=462855 suffer for their ignorance]]. Might be more of [[MentorMascot Mentor Mascot]].

* ''Webcomic/TowerOfGod:'' Rachel to Bam. [[spoiler: [[BrokenPedestal Until stuff happens.]]]]

* ''LightNovel/BanishedFromTheHerosParty:'' Red, a.k.a. Gideon, serves as this to his younger sister Ruti and Al, a boy in the village he retires to. At the start, Ruti knew nothing. Nowadays, she is an expert in fighting and information gathering, all of which her brother taught her. She even imagines a HelpfulHallucination of him when she needs to think. Al, meanwhile, is trained both by Rit and Red. While Rit is an expert with Al's WeaponOfChoice, Red also has so much experience that Al is in awe of Red's strength.

However, just because the Big Brother Mentor cares about the hero doesn't mean that he won't rebuke him if he gets out of line, and he would even go as far to deal with him physically. He only wants the best out of the hero, but won't hesitate to educate him the hard way if the hero shows reluctance to learn or has a tendency to run headlong into danger. In essence, he's the ideal big brother figure who knows when to get friendly or strict.

** Prussia tries to be this to Germany as well, but is too wild and kinda... immature to do it fully. He succeeds a little more with a young America, however.

** Itachi is a huge one for Sasuke until he killed their whole clan, [[spoiler:but since the clan was planning war anyway, Itachi was doing the right thing and above all he couldn't kill his younger brother Sasuke and left the latter alive. Itachi still looked after Sasuke afterwards despite Sasuke believing he was evil, urging his younger to become stronger and ''be a better person'' (which Sasuke didn't listen to)]].

*** For that matter, the relationship between Ace and Luffy play this almost completely straight. Luffy obviously looks up to Ace, who's older, stronger, and more mature.

** Subverted post-Crisis. Kara was actually older than Superman, and she expected to take care of her baby cousin, but after her ship launched, it was stuck in a Kryptonite debris field for 30 years, during which she was in a coma. Although she eventually reached Earth, her cousin was now older and wanting to be her mentor and caretaker.
** Subverted in the New 52. Superman thinks he must help and guide his teen cousin. Everyone thinks she would be better off with him... but Supergirl, who protests that she doesn't need or want any help.

** Despite being there being a roughly forty-year age gap, Warren Worthington III and Sean Cassidy have this kind of relationship, with an edge of VitriolicBestBuds (one of Warren's earliest lines is to snark that Sean is much older than he looks, "but refuses to have the decency to look it", thanks to a NoodleIncident). Sean guides Warren, encouraging him out of his self-imposed shell, based around fears involving his RazorWings, and nearly kills Wisdom when he realises that the other man set Warren up so that he'd end up having to kill someone and would therefore be easier to mould into a soldier.

* Kerlongsj could act like an example for some women in ''Fanfic/InfiniteStratosToTheOtherEndOfTheWorld''. Despite being AFatherToHisMen, in Anaton's case, it's literal because the boy is his son by adoption. Still, because of their not-so-small age difference, Kerlongsj being twenty-two and Anaton being twelve, they're more like this. It would feel a bit awkward for the two to act like they're supposed to. Kerlongsj will scold Anaton when he messes up, but he isn't as strict with him as Chifuyu is with Ichika, but won't tease him like Tatenashi.

* In ''Film/{{Battleship}}'', the main character Alex is a directionless loser who's all but forced into the military by his older brother in the hopes that it'll straighten him out. The older brother is successful and straightlaced... and his death early on in the movie motivates Alex into becoming a better soldier.

** In ''VideoGame/FireEmblemAwakening'', [[ChildMage Ricken]] views [[TheHero Prince Chrom]] as this ever since he saved his life and protected him from bullies. In one of the DLC's, [[ReligiousBruiser Libra]] has a talk with [[HeroicComedicSociopath Henry]] that gives ''very'' strong vibes of the trope as well.

%%** Goro Daimon is this to Kyo Kusanagi in .

* ''VisualNovel/MinotaurHotel'': Asterion used to have two such mentors that he had strong connections. First is Androgeos, his actual brother, who acted kindly towards Asterion despite his curse and even [[spoiler:stopped him from being plunged into Tartarus during his after-life.]] The other is Phroneos, who while not a blood sibling, he took care of Asterion when he was young, during which they grew a tight relationship.

-->'''Jack:''' Ah hah hah! What a scene, man, whoo-ee! And then they just plop you out here like a naked baby in the woods, heh heh, how about that? Ahhh... Look kiddo, this is probably a lot for you to take in, so why don't you let me show you the ropes, whaddaya say?

* In ''Franchise/{{Noob}}'', Ystos, the healer of Justice guild's main roster, was quite involved in the Noob guild even before he enrolled his second avatar in it. He averts the WeUsedToBeFriends situation Arthéon has with the other members of Justice guild, gives them an experienced player's advice when he notices that they're in a dead end and occasionally gives a helping hand. He also happens to be a little younger than most of the guild and the trope is reinforced when it comes to Sparadrap, the Noob guild's own healer [[spoiler:who happens to be Ystos' older but not-too-bright brother]].

* Inverted on ''WesternAnimation/FamilyGuy'' by Stewie Griffin, who functions as a ''Little'' Brother Mentor to his older siblings Chris and Meg. He's shown more concern for his brother's and sister's welfare than their parents ever have, and tried to help them with their problems.

This is a subtrope of TheMentor.

** [[ComicBook/{{Nightwing}} Richard "Dick" Grayson]] decided early on to take a more active role in the mentoring of the third Robin, [[ComicBook/RobinSeries Tim Drake]], than he did with the second, and the two developed a sibling-like relationship in the process. This was so well-liked by fans that ''Nightwing'' writer Chuck Dixon chose to devote what is normally a landmark issue - #25 - of that series not to a major battle or character death, but to Tim and Dick discussing life, Batman, and Dick's [[ChickMagnet seemingly endless parade of hot girlfriends]] for an entire issue (although they were doing that [[CasualDangerDialog while blindfolded, fighting bad guys, on a moving train]]).

** In ''Anime/FullmetalAlchemist'', Hughes is Roy's Big Brother Mentor, hitting pretty much every single qualification for one listed above at some point. He is one year older, but he has a family whereas Roy doesn't, and thus a very different perspective on life. He has one notable moment of snapping out of his easy-going attitude.

* [[spoiler:Zuko]] for Aang in the second half of the third season on ''WesternAnimation/AvatarTheLastAirbender''; made all the sweeter by the ([[{{Reincarnation}} sort of]]) LukeIAmYourFather revelation that season.

** Roy Fokker's {{Expy}} Mu La Flaga from ''Anime/MobileSuitGundamSEED''. He's actually referred to as Kira's sempai on one occasion.
*** In ''Anime/MobileSuitGundamSEEDDestiny'', Athrun Zala tries to do this for Shinn Asuka. It doesn't really work, as Shinn is too messed up to listen, and [[BrokenAce Athrun]] doesn't really have the people skills to pull it off.

** In ''VideoGame/TheLegendOfZeldaTwilightPrincess'', Rusl, the Ordon swordsman and Colin's father, is this to Link. It's stated that he was responsible for teaching Link everything he knows and can be viewed as either a sample of this trope or a straight father figure. Their relationship is more depicted as this in the manga adaption.
** In the backstory of ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', Link himself served this role to the "Big Bad Bazz Brigade", a trio of Zoras that he mentored in swordsmanship.
*** Daruk is this to Link, as they are long-time friends and Link is the last to join the Champions. Daruk is the one to suggest formally inducting Link to the group with a traditional ceremony and later on, Daruk advises Link on how to better get along with Zelda.
