[[caption-width-right:348:[[{{ComicBook/Nightwing}} One]] ComicBook/{{Robin}} to [[LegacyCharacter another.]]]]

This character is the hero's good friend. The hero (or whoever his protege may be) can fool around with him, go to the bar with him for a drink and talk about some good old man-business with him. Additionally, the character, being older (though mental age matters more than physical age) and wiser than the hero, also acts as a mentor to the hero in times of need or advice.

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.

[[CoolBigSis Female variants of this trope]], or examples where the protege is female, are much less common but not unheard of.

In {{Anime}}, this kind of character is often [[{{Honorifics}} addressed]] using the more informal "Aniki" instead of "Onii-san".

Often, this character is [[MentorOccupationalHazard doomed to die]] -- both to bring the Hero out of the character's shadow, [[TragicBromance and to give the character an emotional buildup]].

This is a subtrope of TheMentor.

If he and TheHero are romantically involved, or just have enough HoYay or ShipTease, this can become LoverAndBeloved (or a MentorShip if one party is of the opposite gender). Differs from AloofBigBrother in that the Big Brother Mentor doesn't have to be a ''literal'' big brother and actually gives a damn about his "little siblings" (Or shows it quite more often than a merely emotionally repressed AloofBigBrother). Compare with the SternTeacher, tough and strict but loved by everyone. Contrast with DisappointingOlderSibling. Not to be [[Literature/NineteenEightyFour confused with]] DracoInLeatherPants.

%%* Kuwabara to Yusuke later on in ''Manga/YuYuHakusho''.
%%* Dino to Tsuna in ''Manga/KatekyoHitmanReborn''.
* Kamina to Simon in ''Anime/TengenToppaGurrenLagann''; Simon even calls him "aniki". The dub uses "bro", and Kamina even refers to the two as "BloodBrothers" a few times.
* As Setsuna's [[SempaiKohai sempai]], Kira in ''Manga/AngelSanctuary'' often acts that way towards him. Yue Katou too to some extent. Sara Mudou calls Setsuna "aniki," but towards his own sister he is more of a... [[BrotherSisterIncest oh well...]]
* Ango from ''Manga/SevenSeeds'' is this to several people, mostly because he is somewhat of a control freak. He originally took Shigeru under his wing, helping him improve his physical abilities and making sure he got up in time, but also making him independent. He eventually becomes this to [[ShrinkingViolet Natsu]], too, though his forceful way of helping intimidates her a lot.
* ''Anime/DragonBall'':
** Yamcha could be seen as this to Kid Goku early on, but definitely not in the later series.
** Tien for Chiaotzu ''big time'' even without Master Crane, Chiaotzu still follows Tien with question and he dies (twice) Tien tends to go apeshit.
* ''Anime/DragonBallZ'':
** Piccolo towards Gohan, though it mostly overlaps with ParentalSubstitute. Technically speaking Piccolo is only being four years older than Gohan at the start of Dragon Ball due to [[PlotRelevantAgeUp rapid aging]].
*** Krillin plays older brother/uncle figure to Gohan.
** Gohan is to kid Trunks in both timelines, future Gohan teaching and inspiring future Trunks and who Trunks still remembers long after his death. Teen Gohan does the same to Trunks in the main timeline as seen in the Buu saga, Bulma evens muses in ''Wrath of the Dragon'' that Trunks is jealous of Goten for having a older brother.
*** Tapion fills this role for kid Trunks as well, especially since he lost his own younger brother.
* ''Anime/{{Macross}}'':
** Roy Fokker in ''Anime/SuperDimensionFortressMacross''[=/=]''Anime/{{Robotech}}'' is maybe the UrExample for anime. [[spoiler: And midway through the series, he kicks it. Damn pineapple salad and inner bleeding.]]
*** He also plays this role in prequel ''Anime/MacrossZero''.
** Ozma Lee in ''Anime/MacrossFrontier'' is ultimately played as a subversion of the archetype. He's an older mentor, and even flies Skull One, but it's usually the other characters who give the most useful advices, he's made lots of mistakes, and [[spoiler: ''he completely fails to die, even when pineapples are involved.'']]
*** And he's too much of a JerkAss, anyway. [[FriendlySniper Mikhail]] (he's one of the aforementioned other characters) plays the part much, ''much'' better. [[spoiler: [[{{Tearjerker}} Sadly, this includes the dying part]].]]
* ''Manga/JoJosBizarreAdventure'':
** An evil example comes in Part 5 with the two mafia members Pesci and Prosciutto. Pesci is the little brother and ironically like other mentors Prosciutto dies by getting run over by a train and getting lodged in the wheels before Pesci gets how to be a good mafia worker. Then he dies by getting his head unzipped from his body and thrown into a lake.
** In Part 7, Gyro Zeppeli's position as Johnny's friend and a teacher could fit this trope as well.
* ''Manga/{{Berserk}}'', Guts is the big mentor for Ricket and Isidro. Especially for latter, Guts even gives him lessons though he overlaps with father figure.
* 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.
** In an evil example of this trope from [[Manga/FullmetalAlchemist the manga]], Pride acts as this towards Wrath, the youngest of the Homunculi. This becomes quite ironic when you learn [[spoiler: Pride masquerades as his son, Selim Bradley]].
* In the anime version of ''Anime/{{Planetes}}'', Hakim Ashmead fills this role for Hachimaki, at least until his [[spoiler:HeelFaceTurn where he was revealed to be TheMole for the terrorist Space Defense Front]].
* 2 prominent pairs on ''Anime/YuGiOhGX'': Sho adopts Judai as his "aniki," whom he prefers to his biological AloofBigBrother (until Judai [[HoYay dumps him for Johan]]). Manjyome also looks up to Asuka's brother Fubuki. Though he does also call Fubuki shishou (master) as well as big brother. The big brother part seems to be more because of his crush on Asuka, since if he ever married her, they would *be* brothers.
* The ''Franchise/{{Gundam}}'' franchise has several examples as well...
** ''Anime/MobileSuitGundam'' has Ryu Jose, who doesn't actually teach Amuro how to pilot a Gundam, but how to be a man and soldier; [[spoiler: he of course performs a {{Heroic Sacrifice}}.]]
*** Lieutenant Sleggar Law would've been one of these, had he gotten more screentime. [[spoiler: He ''does'' get the death part, though.]]
** ''Anime/MobileSuitZetaGundam'' has Quattro Bajeena, aka Char Aznable, as the main character's mentor; however, he neither dies nor holds back from kicking ass himself.
*** Zeta Gundam also has Amuro Ray act as a mentor to the main character during one important story arc.
*** Villainous example: Kacricon Cooler is this to Jerid Messa. [[spoiler: And he gets a FamilyUnfriendlyDeath early in the series.]]
** ''Anime/MobileSuitGundamUnicorn'' has Marida act as a female variant to both Banagher and Audrey/Mineva. Flaste Schole is also a bit of one to Banagher.
** The closest to a BigBrotherMentor in ''Anime/MobileSuitGundamWing'' would be Trowa Barton, the GeniusBruiser BigGuy of the FiveManBand. His interactions with TheSmartGuy Quatre Raberba Winner walk the line between this and straight-up HoYay, but he also helped Heero Yuy sort his thoughts after his infamous suicide attempt, and gave Wufei support after he loses to Treize.
** Don't forget 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.
** ''Anime/MobileSuitGundam00'''s [[spoiler: Neil Dylandy aka the first Lockon Stratos]] was some kind of advisor to not only Setsuna but the most of CB. Even if he's dead he'll probably return as a spiritual advisor. Still, [[spoiler: Tieria Erde]] seems to fit a bit better in the second season, even dealing some Bright Slaps when needed.
*** Also, [[spoiler: Lyle, Neil's twin younger brother and the second Lockon]] isn't necessarily ''the'' BigBrotherMentor but has his moments as well, specially in episode 18 where he counsels two of his teammates when they had romantic problems.
** And ''Anime/MobileSuitGundamAGE'' gives us Woolf Ennacle playing the role for Flit Asuno ''and'' Flit's son Asemu. [[spoiler: He survives the first season, then epically and tearfully kicks it in the second one.]]
* Played straight and subverted in ''Anime/MobileFighterGGundam''. Argo Gulskii is the oldest, more mature of the Shuffle Alliance and plays the role straight towards Domon and Sai Saici, whereas Schwarz Bruder subverts it by being Domon and Rain's own BBM... [[spoiler: and a clone of Domon's AloofBigBrother Kyouji, who specifically created him with some DG cells [[DeadPersonImpersonation and the dead body of the real Schwarz Bruder]] to play this role before he was fully brainwashed by the Devil Gundam.]]
* Big Sister Mentor example: Freya to Kisara in ''Manga/KenichiTheMightiestDisciple''. Kisara calls her "Freya-nee", even when they were on opposite sides.
* Yashichi, to his followers Sasuke and Hanzo in ''Mirumo de Pon!''.
* ''Manga/{{Naruto}}'':
** 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 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).
** Kakashi's relationship with Obito and his male students, Naruto and Sasuke, can be seen as this. Some fans believe this strongly since Minato (Naruto's dad) looked after Kakashi like a son, making him a metaphorical big brother, but since Minato is dead Kakashi can also been seen as [[ParentalSubstitute a father figure to Naruto]].
** Madara towards his younger brother Izuna, though he was not above [[EyeScream taking his brother's eyeballs]].
* ''Manga/OnePiece'':
** Zoro, to Luffy. Given that he's the {{Lancer}}, and {{Fan Speak}} sometimes denotes him as the First Mate of the crew, he often steps in to help Luffy make the tough choices given [[IdiotHero Luffy's personality]]. This was especially obvious when [[spoiler: Usopp temporarily left the crew and Zoro both supported Luffy's decision to fight Usopp and later forced him to wait for Usopp's apology when it became apparent that Usopp wanted to return to their crew]].
*** Chopper also looks up to Zoro in this fashion.
** Sanji, to Usopp. Though the former makes it clear at times he doesn't care as much about Usopp as he would Nami, Robin or Chopper, Sanji still cares for Usopp greatly and gives Usopp vital advice when he needs it. Sanji explicitly showed his care for Usopp when Luffy ''almost'' told him to leave the crew but was stopped by Luffy kicking him across the room and telling his captain not to say something "he couldn't take back", when Usopp did leave Sanji chased after him along with Nami and Chopper. During the battle at Enies Lobby, Sanji was the one to make Usopp see his self-worth by stating only ''he'' could save Robin by using his [[ImprobableAimingSkills skills]].
*** Sanji also gives Chopper lessons on being "a real man" and did so twice in Enies Lobby: when Robin was not telling the truth about her past he tells Chopper that "''a real man forgives a woman's lies''". And when Usopp was left beaten and bloody by Luffy, Sanji had to physically restrain Chopper from helping Usopp, saying Luffy had already shown pity to Chopper in the face of defeat and Chopper would've stomped on Usopp's pride by treating his wounds.
** From what we see in {{flashback}}s, it seems that Marco was this to Ace when he was first[[spoiler: captured by the Whitebeard crew and had trouble accepting [[AFatherToHisMen Whitebeard as his captain and father]].]]
*** 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.
** Though he was very bitter and angry with Franky, Iceberg still invoked this trope and gave Franky his biggest life lesson when Franky's battleships were used by the government to frame Tom Worker's... that whether you want it or not "weapon are made to hurt people". Iceberg also cried upon learning Franky was alive, saying he was grateful.
** Trafalgar Law had one in Rocinante aka Corazon, who showed him genuine empathy when he was brought into the Doquixote Family by Doflamingo. [[spoiler: After Rocinante's death at the hands of his own brother Doflamingo, Law wears to make Doflamingo '''pay''' for it.]]
** Charotte Katakuri is one for all his siblings, they all hold him in high regard and call him "big brother". Brulee especially gloats to Luffy about how boss her older brother is and she's mostly right.
* Albert/004 in ''Manga/{{Cyborg 009}}''. His "little brother" Jet/002 later also has some BigBrotherMentor moments in the Little Psychics mini-arc.
* Tsukushi from ''Manga/{{DAYS}}'' gets one in the form of his team captain Mizuki. Mizuki teaches him how to properly kick a soccer ball (even when his leg was injured at the time) and other techniques to become a better player. He sees potential in Tsukushi becoming an amazing soccer player and team captain some day.
* Subaru Sumeragi becomes this to Kamui Shirou in the ''Manga/{{X 1999}}'' manga and TV series, specially after [[spoiler: Subaru takes a very dangerous JourneyToTheCenterOfTheMind to bring Kamui back from an AngstComa, and realises that deep down both are NotSoDifferent.]]
* Though Tomohiko Yamada of ''Manga/SatouKashiNoDanganWaUchinukenai'' mostly subverts this, he has his moments of wise advice for his younger sister Nagisa... [[{{Hikikomori}} before going back to his room and tuning out the world around him.]] [[spoiler: He plays it heartbreakingly straight towards the end, however, when Nagisa's best friend Mokuzu disappears and Nagisa believes that her abusive father murdered her... and for worse, ''she turns out to be right''.]]
* 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).
* In ''Manga/PokemonSpecial'', Green is this to Yellow in her arc. A female example would be Crystal, to Emerald.
* England was this to America (and most likely to Canada too) in ''Manga/AxisPowersHetalia''. China is considered the older brother of the rest of the Asian countries, such as Japan, South Korea, Macau, Vietnam, Hong Kong and Taiwan, but except for Korea they don't always acknowledge as this.
** And Switzerland dotes on his adorable adopted sister Liechtenstein.
** Subverted with Latvia and Sealand. The first tries to be this, but soon finds out that as a FragileFlower, ''he'' needs [[MoeCouplet the support of the latter]].
** Austria begins as an AloofBigBrother to young Italy, but is this towards Germany.
** 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.
** France considers himself one to all of Europe[[note]]Except for Spain, who he acknowledges as his older brother in turn[[/note]], but only [[TheDitz North Italy]] and [[TheOjou Monaco]] (and possibly [[SitcomArchnemesis England]], at least when he was young) consider him one in return enough to actually call him "big brother".
** Denmark acted as this to young Iceland, combined with ParentalSubstitute. He taught him how to make friends, for one, and proclaims that he raised him.
** The [[NonIdleRich Netherlands]], despite being an AloofBigBrother for the most part, taught his younger siblings [[CoolBigSis Belgium]] and [[PrincelyYoungMan Luxembourg]] a lot about trade and making money.
* ''Manga/FistOfTheNorthStar'':
** Kenshiro towards Bat, as stated when he calls him his "irreplaceable little brother."
** Also Toki and Raoh towards Kenshiro.
** Bat to his fellow orphans.
* 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]].
* ''Anime/FutureGPXCyberFormula'':
** Osamu, Kaga and Johji to Hayato, as they dispense their racing wisdom to help him. Kaga in particular, since he helps Hayato hone his driving skills in a crash race.
** Lope is this to Hiyoshi, as he helps the latter to get back into racing again after leaving the Sugo team.
* Sakuragi of ''[[Manga/RainbowNishaRokubouNoShichinin Rainbow]]'' might as well be the king of this trope. Seriously, his nickname is even An-chan ("Bro").
* [[Manga/GreatTeacherOnizuka Onizuka]] dips into SenseiForScoundrels occasionally, but he's a genuine mentor to Noboru all through the manga series. [[CrazyAwesome Even if his methods are somewhat extreme]].
* Somewhat subverted in ''Manga/{{Naruto}}'' between Itachi and Sasuke. Itachi challenges Sasuke to see him as a barrier he must overcome, though he uses rather disturbing methods to accomplish this.
** Konohamaru considers Naruto and Shikamaru to be Big Brother Mentors, too.
** Shisui Uchiha was apparently this for Itachi during their childhood. [[spoiler: Itachi, in turn, played this role briefly for Naruto when he was resurrected.]]
* ''Anime/PuellaMagiMadokaMagica'': Mami Tomoe is a veteran MagicalGirl who often mentors rookies and is also their big sister figure. In both the main story line and the ''A Different Story'' spin-off she shares tea and cake with her juniors. [[spoiler: In the former, [[WhamEpisode she dies in Episode 3]].]]
** Played to heartbreaking effect in [[spoiler:the third timeline in Episode 10 of the main series after Sayaka turns into a Witch - Mami becomes so terrified of the AwfulTruth about the fate of Magical Girls she decides that [[MercyKill mercy killing]] everyone would be better than everyone becoming a Witch. She gets as far as shooting Kyoko's Soul Gem and taking aim at Homura before Madoka has to shoot Mami in order to stop her.]]
* ''Anime/TigerAndBunny'' has an interesting example; instead of giving the protagonist a Big Brother Mentor, they made the protagonist ''himself'' play this role where a number of younger characters were concerned. It's even {{invoked| trope}} in the third episode, where Kotetsu's boss suggests he take this approach with Barnaby.
-->'''Lloyd Alexander:''' He's young, so why don't you try to lead him? You've been doing this for much longer, after all.
* Sora is this to Ikki in ''Manga/AirGear'', even going so far as to teach him how to properly utilize the [[BlowYouAway Wing Road]]. [[spoiler: This attitude changes when Sora announces his FaceHeelTurn and reveals that he was using Ikki and helping him become better so that the Wind Regalia can be made for him to take. All of this is just step one of his plot to become Sky King. This quickly leads to Ikki having a HeroicBSOD moment.]]
* Future Gohan is this to Future Trunks in ''Anime/DragonBallZ''. Slightly less so in the main timeline to Goten and Present Trunks. Goku's best friend Krillin was this to Gohan.
** Nail was also like this to Dende, even after Nail's [[FusionDance fusion]] with Piccolo.
* In ''AudioPlay/SaintBeast'', Goh is occasionally called "big brother" by Shin, Rey and Gai for being TheLeader of their group.
* Mamoru from ''Franchise/SailorMoon'' is the LoveInterest for Usagi, the TeamDad for both Senshi teams, ''and'' the BigBrotherMentor to the Inners, especially to Ami aka Mercury.
* ''Manga/{{Bleach}}'': Via CharacterDevelopment Byakuya Kuchiki has become this to ''both'' his adoptive sister Rukia and his lieutenant Renji. Until the Soul Society arc, Byakuya [[AloofBigBrother had retained a rigid, formal distance from both of them.]] After taking Ichigo's advice to put compassion before duty if they ever clash again, Byakuya's become much more open about his affection for the two, and much more openly protective of both. By the final arc, he's someone both Rukia and Renji clearly look to for support and guidance.
* In ''Manga/SlamDunk'', a big part of Takenori Akagi's CharacterDevelopment involves him becoming this towards Hanamichi Sakuragi. Once Sakuragi grows into his own skin and his basketball role as well, he says that [[LampshadeHanging he considers himself "the Gori's little brother".]]
* In ''Manga/ACruelGodReigns'', Lindon acts as this for Ian, giving him advice on how to deal with first getting Jeremy to confess (though not {{Mind Rape}} him like Ian would like), and later on how to deal with his romantic feelings for Jeremy.
** Valentine also acts as a sort of BigBrotherMentor for Jeremy, despite being the same age, if not younger.
* ''Manga/AttackOnTitan'':
** Reiner Braun is seen as something of an older brother to the entire 104th Trainee Corps, and becomes an important influence on [[TheHero Eren]], helping shape him into a capable soldier. It ends up resulting in [[spoiler: Eren noting that one of Reiner's mistakes as TheMole was [[NiceJobFixingItVillain teaching]] him to fight]]. After the TimeSkip, he's become one to [[spoiler: the younger Warrior Candidates competing to be his successor]].
** WordOfGod reveals that Zeke was one to the other Warriors in the past, though he's ''perfectly'' willing to [[CurbStompBattle remind them]] of their [[WeHaveReserves place]] should they challenge him.
* ''Manga/DetectiveConan'':
** Toyed with when, years ago, a man named Shuichi Akai promised his [[spoiler:now deceased girlfriend Akemi Miyano]] that he'd help her younger sister, who has since [[spoiler:become Ai Haibara]]. He's currently fulfilling his word (DeclarationOfProtection included), and he also helps [[spoiler:Ai's friends (including Conan)... under the fake identity of Subaru Okiya]].
** 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.]]
** When the Detective Boys want to beat Conan and solve a mystery before he does, Heiji Hattori steps in and helps them out by secretly giving them hints to the mystery. When they fail to beat Conan to the solution, he gives them encouragement and turns it into ALessonInDefeat, telling them that they need to start doing the work themselves. Hattori also convinced them to let him help by showing them a picture of what ''looks'' like Conan bowing to him and suggesting he was this to Conan.
* In ''Manga/RurouniKenshin'', the title character had ''three'' of these in his backstory: [[http://http://en.wikipedia.org/wiki/Kido_Takayoshi Kogoro Katsura]] was the leader of the ''ishinshishi'' group Kenshin was a part of, [[http://en.wikipedia.org/wiki/Shinsaku_Takasugi Shinsaku Takasugi]] was the one who brought him into the group in the first place, and Iizuka was his monitor/lookout. [[spoiler: Too bad that Takasugi died of illness, Iizuka was TheMole, and Katsura was later disgraced.]]
* Sisterly example with Yomi Isayama to Kagura Tsuchimiya in ''Anime/GaReiZero''.
* On ''Manga/BlueExorcist,'' one of [[AntiAntiChrist Rin]]'s mentors is his [[PolarOppositeTwins twin brother]], [[BadassBookworm Yukio]]. The thing is, technically Yukio is the ''younger'' brother.
* Gareki is this (somewhat) to Nai in ''Karneval''
* [[JerkWithAHeartOfGold Kannagi]] of ''Manga/ArataKangatari'' takes on this role towards Hinohara and the rest of the group. Yataka as well, though to a lesser extent.
* Chrono is this for Fate in ''Anime/MagicalGirlLyricalNanohaAs''. Although he's only shown in this role before she [[HappilyAdopted became his sister]].
** Nove is both this and a CoolBigSis for Vivio and her friends in ''[[Manga/MagicalGirlLyricalNanohaVivid ViVid]]'' (even if she claims otherwise). They even call themselves "Team Nakajima" in tribute.
* ''Anime/ZoidsChaoticCentury'': Irvine is this to Van. And Van himself is one to Prince Rudolph.

[[folder:Comic Books]]
* Due to the nature of its "legacy" focus on characters, these pop up quite often in Franchise/TheDCU.
* Franchise/{{Batman}}:
** Although it's a bit moot now that they're ''actually'' brothers, [[ComicBook/{{Nightwing}} Richard "Dick" Grayson]] decided early on to take a more active role in the mentoring of the third Robin, 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 while blindfolded, fighting bad guys, on a moving train).
** Damian Wayne also sees Dick Grayson like this, genuinely respecting him and Dick is one of the few people who believes in him and helps steer Damian in the right direction. In ''[[ComicBook/DCRebirth Rebirth]]'', Damian himself seems to want to take this role to the [[ComicBook/{{Superboy}} newest Superboy, Jon Kent.]] While stern and derisive to the point of getting into numerous arguments and scuffles with the Half-Kryptonian, many of his actions can be seen as overprotective of the younger superhero and he insists on imparting lessons and advice into almost every conversation they have.
** Bruce himself is sometimes treated as this to the Robins, although it's far more common for him to be a ParentalSubstitute. Under Creator/GrantMorrison, Dick Grayson specifically called Bruce his brother.
** In ''Comicbook/Batgirl2009'', Barbara Gordon -the original ''Comicbook/{{Batgirl}}''- helped and mentored Stephanie Brown, who was determined to take up the title and the Batgirl mantle.
* Although he initially played the role of the older brother who didn't want to be around the younger one, [[Franchise/TheFlash Wally West]] eventually grew quite fond of Bart "Impulse / Kid Flash" Allen (who's technically his cousin, once removed).
* Franchise/WonderWoman and [[ComicBook/WonderGirl Donna Troy]] refer to each other as sisters, although it's been a while since Donna's actually been mentored by Diana. Much like the Batman / Nightwing / Robin relationship above, however, Donna served as an older sister to the second Wonder Girl.
* Franchise/{{Superman}}:
** Superman was this to ''Comicbook/{{Supergirl}}'' in the Silver Age. He took care of his cousin and trained her until Kara was ready to go solo.
** 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.
** In ''ComicBook/RedDaughterOfKrypton'' Superman has to tell [[Franchise/GreenLantern Guy Gardner]] he can't keep his cousin with him if she doesn't want to stay. So Guy became Kara's brotherly mentor, helping her find herself and manage her anger.
** In ''ComicBook/ManyHappyReturns'', Linda Danvers becomes this to Kara Zor-El, taking care of her and teaching her how to be a hero.
* In ''ComicBook/{{Supergirl}}''/''Comicbook/{{Batgirl}}'' story ''ComicBook/ElseworldsFinestSupergirlAndBatgirl'', Barbara Gordon's parents got murdered, and the Waynes took her in. Bruce helped her and mentored her while she was growing and preparing to become Batgirl.
* ''ComicBook/XMen'':
** ComicBook/{{Wolverine}} to practically any younger female character. Most notably {{Kid Sidekick}}s Jubilee and Kitty Pryde. In ''Wolverine'' #16, a reporter is going around asking people what they think of Wolverine. Jubilee says he's an amazing big brother. Kitty takes it a little further -- she admits that she'll probably never get married because she always compares the guys she meets to Wolverine, and they never measure up.
** ComicBook/{{Gambit}} is this to Wolverine's clone/daughter ComicBook/{{X 23}} in her solo self-titled series. Although they are on more equal terms than some of the other examples.
** Laura ''herself'' becomes one to her younger "sister"/clone, Gabby, in ''All-New Wolverine''.
* Maid Man and Cyndablock act like this to ComicBook/{{Empowered}}, showing her that not all superheroes are assholes. That it's the {{transvestite}} and the literal blockhead who actually are nice to her must say something about how much being a low-tier superhero sucks.
* Franchise/SpiderMan tends to act like for the younger heroes, especially those that feel they can't really trust the adult superheroes. A large reason is that Spidey started his superheroics at their age and so he can relate to the struggles of balancing superheroism and teenage life. As a result, alot of the young superheroes look up to him and he in turn tries his best to [[http://atopfourthwall.tumblr.com/post/127479759428 advise them on what he has learned as being a former teenage superhero.]]

[[folder:Fan Works]]
* ''Fanfic/ACrownOfStars'': TJ plays this role to Shinji during the last half of the story, counselling Shinji and helping him to make a decision when he is feeling insecure and wary.
* ''Fanfic/AdviceAndTrust'': Asuka -and Shinji- became this to Rei after the former realized the latter was being treated like a puppet. Asuka convinced her to stop taking a medication regimen tailored to turn Rei into an emotionless doll, and she and Shinji helped Rei to move in a decent apartment and improve her social skills. Rei started to model her behaviour patterns after Asuka, and Asuka and Shinji became very protective of Rei.
* ''Fanfic/DoingItRightThisTime'': Ritsuko becomes a mix of this and CoolBigSis to Rei after discovering [[spoiler:Rei is a clone of her mother.]]
* The [[WisePrince dwarven]] [[GuileHero noble]] in ''Fanfic/DragonAgeTheCrownOfThorns'' assumes this role in relation to the [[LightningBruiser dwarven commoner]].
* A rare female example of this trope: In the ''Manga/DeathNote'' [[AlternateUniverseFic AU]] ''FanFic/PointOfSuccession'' Naomi Misora is this to Light (who in this fic is a [[NewMeat rookie]] [[TheProfiler criminal profiler]] with a DarkAndTroubledPast). Naomi takes him under her wing at the UsefulNotes/{{FBI}} [[VitriolicBestBuds but she also frequently teases him in a "big sis" kind of way.]]
* ''[[Fanfic/GodsAngelsAndKings Hail To The King]]'': ''Series/ZoneFighter'' acts that way towards Shinji. He teaches him to fight and to be more confident, assertive, sefless and courageous. Through this process Shinji [[GrewASpine grows a spine]] and becomes a hero.
* Another female example in ''FanFic/AceOfSpades'' where [[{{Franchise/Batman}} Harley Quinn]] is this to [[Literature/HarryPotter Harry Potter]].
* Clint Barton has elements of this towards Harry in ''Fanfic/ChildOfTheStorm,'' teaching him how to fly a Quinjet, sparring with him, and basically being the cool big bro that Harry never had. Clint takes this role in large part because he's the youngest Avenger and can relate best to Harry.[[note]] [[ComicBook/CaptainAmerica Steve]] is younger than Clint by a couple years, not counting his time in the ice, but he's such a LivingLegend that it takes Harry, who's at first quite shy, longer to connect.[[/note]]
* Main focus of ''[[http://www.fanfiction.net/s/4862939/1/The-Next-Dragon-Warrior The Next Dragon Warrior]]'' where Po helps out the younger Jo.
* Yet another female example: Twilight Sparkle is this to Trixie in ''Fanfic/PonyPOVSeries''.
** Likewise in ''Fanfic/GettingBackOnYourHooves''. [[spoiler:Trixie even admits later Twilight's like a sister to her.]]
* Rainbow Dash behaves this way toward Medley in ''Fanfic/AceCombatTheEquestrianWar''. By the end, Rainbow herself admits that, to her, [[spoiler: Firefly]] is like an older sister she never had.
* In Ah! Archfall!, Jago is a literal version; his brother (Bob) is sent to him to learn anger management. Jago encourages him to learn how to control himself in a fight, eventually culminating in Bob's disastrous duel with Skuld, after which Jago delivers swift justice in a beating so severe that he BREAKS HIS OWN HAND in the process. [[spoiler:He also secretly supports Bob's tentative relationship with Chrono, despite the fact that she is training to be a Valkyrie and must therefore remain celibate.]]
* Reggie to Brandon in ''FanFic/{{Pokeumans}}'', training him and helping him with different things he needs throughout the story.
* ''Fanfic/ThousandShinji'': Deconstructed. Shinji is this to Rei. When they met she behaved like an emotionless doll. He helped her to discover emotions and feelings and find a purpose to live, and she became a more self-reliant, more confident, happier person. However he did this for converting her to ''[[TabletopGame/{{Warhammer 40000}} dark gods of Chaos]]'', and she became creepier than before. Additionally her mind was not ready yet to deal with her new emotions and powers, so that when Shinji and Asuka got together she was so consumed with jealousy -because Shinji was happy with Asuka- and despair -because Shinji's brotherly love was insufficient to her- that she became a {{Yandere}}.
* [[AlmightyJanitor Kosuke the Eternal Genin]] becomes one for Naruto in ''[[https://www.fanfiction.net/s/11491965/1/Memories-Of-Others Memories Of Others]]'' after the latter becomes a genin without a team. He spends their wall patrols teaching Naruto various things that aren't taught in the academy such as international politics and nonverbal communication.
* 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 like Chifuyu is with Ichika, but won't tease him like Tatenashi.

[[folder:Films -- Animation]]
* In ''Disney/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]].

* Han Solo to Luke Skywalker in ''Franchise/StarWars''.
** Obi-Wan Kenobi to Anakin Skywalker, in the prequel trilogy. You know, before he was old.
** He even refers to Anakin as his brother in Episode III, while Anakin tells him he is like a father to him in Episode II.
* ''Film/XMenFirstClass'': Because [[Characters/XMenFilmSeriesProfessorCharlesXavier Charles]] and Hank share a lot in common, Xavier treats [=McCoy=] more like a little brother than the other young recruits.
* Ken to Ray in ''Film/InBruges''.
* Marcus and Kyle Reese develop this dynamic in ''Film/TerminatorSalvation''.
* Mr White to Mr Orange in ''Film/ReservoirDogs''
* 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 succesful and straightlaced...and his death early on in the movie motivates Alex into becoming a better soldier.
* In ''Film/FromDuskTilDawn'' Seth is this to Richard.
* ''Film/{{Dredd}}'': If Anderson is any indication, Dredd gives his rookie partners both the criticism and praise they need to bring out the best in them.

* This is OlderThanTheyThink: In Literature/TheBible, when the archangel Raphael took a human form to find and fight the demon Asmodeous, he posed as a young man named Azariah who played this role for young Tobias, the youth who was qualified to marry Sarah, the girl whom Asmodeous lusted after and tormented by killing her husbands right after the wedding.
** For the reader's enlightenment: this story is from the Book of Tobit, which is not considered part of the Bible by either Jews or non-Catholic/Eastern Orthodox Christians. Although it is still considered a useful read.
** Jonathan can be considered this to David. He's at least some years older than David, and guides and protects him; he accepts that Jehovah has chosen David to succeed Saul, and David is ''devastated'' when he and Saul die.
%%* Nico to Cal in the ''Literature/CalLeandros series.''
%%* Zaknafein to Drizzt in ''[[Literature/TheDarkElfTrilogy Homeland.]]''
* Literature/HarryPotter has Sirius Black, his godfather, and Remus Lupin. [[spoiler:Too bad that both of them die.]]
** To elaborate it's worth noting that this is a major difference in Sirius' portrayal in [[Literature/HarryPotterAndTheGobletOfFire Book 4]] and [[Literature/HarryPotterAndTheOrderOfThePhoenix Book 5]]. In Book 4, he is still on the run and very sharp about potential danger, and acts mostly responsibly toward Harry. He constantly reminds him to lie low, stay out of trouble, and not take risks to see him. Harry on several occasions in [=GoF=] expresses relief that he is nearby. In ''Order of the Phoenix'', Sirius, as noted by Hermione, begins to behave more recklessly, mainly because he is stuck at his childhood home (his childhood was pretty crap and actually ran away at 16, so he very understandably does not like being there), subject to taunts about his lack of "usefulness," and there are several hints that he is not mentally stable. It is in ''Order of the Phoenix'' that Harry begins to worry about Sirius doing something risky to see him, that Molly accuses Sirius of [[ReplacementGoldfish being unable to tell Harry and James]] apart, and that Sirius becomes careless about his disguise.
* 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.
%%* ''Literature/TheHost'': Jared Howe to Jamie Stryder.
%%* Tonda for ''Literature/{{Krabat}}'', later Krabat for Lobosch. HereWeGoAgain.
%%* Joscelin to Imriel in ''Literature/KushielsLegacy''.
%%* Merry is this to Pippin in ''Literature/TheLordOfTheRings''.
%%* Seregil to Alec in ''Literature/{{Nightrunner}}'', and also Micum and Beka to Alec at times.
* [[Literature/PercyJacksonAndTheOlympians Percy Jackson]] has Luke Castellan, who looks after Percy when he first arrives in Camp Half-Blood in ''The Lightning Thief'', and even gives him some cool magic items to help in on his very first quest. [[spoiler: It's just a shame that the items are cursed to drag Percy down to Tartarus, and that Luke's the titular Lightning Thief, TheDragon to BigBad Kronos, and one of the main villains of the series]].
** Percy himself is something of the sort towards Hazel and Frank in ''Literature/TheHeroesOfOlympus''.
* Literature/TrappedOnDraconica: Daniar is this for Erowin; taught her martial arts and tries to keep her away from bad habits like drinking during the day. She's too heavy on the 'stern' and not enough on the 'buddy' for Erowin's tastes.
%%* Captain Pausert to the three young witches (sort of) in ''Literature/TheWitchesOfKarres''.
* Amazing to Chuck in ''Film/AmazingGraceAndChuck'', though Chuck's dad initially worries its more like ParentalSubstitute.
* In ''Literature/TalesOutOfTallis'', this is a reoccurring theme. Koert plays the mentor to Jurgen and Liam, who then in turn are the mentors to the next generation. Though Liam is more of a TricksterMentor

[[folder:Live-Action TV]]
%%* Murdock to Face in ''Series/TheATeam''.
%%* Michael Weston in ''Series/BurnNotice''.
* Simon Tam to River in ''{{Series/Firefly}}''. He is kind of a doting big brother but he also has to extend that role far beyond what that would normally imply due to the extreme situation.
* In ''Series/{{Highlander}}: The Series'', Methos falls somewhere between this and a TricksterMentor to Duncan. The only problem is that Methos has spent hundreds of years avoiding fights and thus is disinclined towards beating a lesson into the [[HonorBeforeReason overly stubborn and idealistic]] Duncan, and thus he often has to hope that his points get through Duncan's thick skull on their own merits.
** Duncan was this to Richie before and after the latter became Immortal.
* ''Series/KamenRiderDecade'' - [[PhantomThief Kaitou]], the series' rival Rider, became one of these to Asumu when the cast visited an alternate version of ''Series/KamenRiderHibiki''. It crosses over with MoralityPet, since up until then Kaitou had been more interested in acquiring treasure than fighting villains, and only helped out the good guys when he felt he owed them or that there was something in it for him.
* Gleb Zheglov to Vladimir Sharapov in ''Series/TheMeetingPlaceCannotBeChanged''.
* Arthur may [[WrongGenreSavvy believe himself to be this]] in regard to {{Series/Merlin}}. He occasionally gives Merlin [[PetTheDog well-meant advice regarding women or battle]], although he often completely misreads the situation due to his ignorance of Merlin's powers and true identity.
** He becomes one to [[spoiler:Mordred]] in season five, possibly as a ShoutOut to the original myth where they were father and son. [[spoiler: And boy does it backfire on him.]]
%%* Don Eppes in ''Series/{{Numb3rs}}''
%%* Del Boy Trotter to his younger brother Rodney in ''Series/OnlyFoolsAndHorses''.
%%* Snafu Shelton to Eugene Sledge in ''Series/ThePacific''.
%%* [[EruditeStoner RJ]] in ''Series/PowerRangersJungleFury''.
* In ''Series/TheSarahJaneAdventures'': the Doctor is this to Luke, Clyde and Rani in [[Recap/TheSarahJaneAdventuresS3E5E6TheWeddingOfSarahJaneSmith The Wedding of Sarah Jane Smith]] & [[Recap/TheSarahJaneAdventuresS4E5E6DeathOfTheDoctor Death of the Doctor]].
%%* Tom Paris to Harry Kim in ''Series/StarTrekVoyager''.
%%* Dean is this to his younger brother Sam in ''Series/{{Supernatural}}''.
%%* Toby Ziegler to Sam Seaborn on ''Series/TheWestWing''
%%** And President Bartlet to Toby.
%%* ''Series/WizardsOfWaverlyPlace'': Justin. Most notably in the movie.
* [[DeconstructedTrope Deconstructed]] in ''Series/{{Scrubs}}'' with JD. Every time he's in a teaching position he tries his hardest to make his interns/students like him, but usually all it does is cause him to lose authority and respect. This is sharply contrasted with JD's ''own'' mentor Dr. Cox, who has a ''very'' harsh [[SinkOrSwimMentor sink-or-swim]] approach that is nontheless generally accepted to be great for teaching. Cox even delivers a WhamLine to JD in regards to this.
-->'''Cox:''' I wanted you to see just how ridiculous you truly are, ''constantly'' chasing their approval.\\
'''JD:''' So I'm supposed to be like you, and just "rule by fear"? Perry, they ''hate'' you.\\
'''Cox:''' Yes, they do. And sure, I could be a little bit kinder, but that's not going to happen and here's why: we're creating ''doctors'', not ''kindergarteners.''\\
'''JD:''' They need me.\\
'''Cox:''' ''Do they?'' Because I don't ever remember holding your smooth little doll hand, and you turned out to be not too horrible a doctor.
* ''Series/Supergirl2015'': Superman, unsurprisingly. When he shows up, it's generally as "the ultimate supportive big brother". There's a minor twist in that Kara is technically older than him, but spent years in stasis en route to Earth.
%%* Eric was this to an orphan named Tommy in ''Series/BoyMeetsWorld''.

[[folder:Video Games]]
* Paul in ''VideoGame/DeusEx''. He will try to encourage the player to use non-lethal tactics, and will chew out the player if he/she chooses to do a take-no-prisoners gameplay.
* Inverted with Hakuoro playing the big brother to Oboro in ''VideoGame/{{Utawarerumono}}''. He even uses 'aniki' which gives Hakuoro pause for a moment.
%%* In ''VideoGame/CrisisCore'', Angeal is this to Zack, who becomes this to Cloud.
* Axel is this to both Roxas and Xion in ''[[VideoGame/KingdomHearts358DaysOver2 Kingdom Hearts 358/2 Days]].''
** Riku also demonstrates this trope towards the hero, Sora, throughout [[Franchise/KingdomHearts all of the games]]. Though he did go through a stint of AloofBigBrother and RivalTurnedEvil in the first game, he quickly grew out of it.
** Terra in ''[[VideoGame/KingdomHeartsBirthBySleep Birth By Sleep]]'' is also this to Ventus [[spoiler: and Riku, for a brief moment, explaining where he gets it from]]. [[spoiler: Later events and Ven's status as a MacGuffinSuperPerson push Terra towards KnightTemplarBigBrother territory.]]
* 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.
%%* Chris Redfield to Claire Redfield, literally, in ''Franchise/ResidentEvil''. Or so it's been implied.
* Rei is a roguish variant on this to [[TheHero Ryu]] and Teepo in ''Videogame/BreathOfFire 3'', teaching them how to mug people and hunt efficiently. [[spoiler: Though he appears to die when [[KnightOfCerebus Balio and Sunder]] torch the heroes home, allowing Ryu to begin his adventure, he returns after the TimeSkip as an AntiHero {{Lancer}} to the (now more well-rounded and heroic) Ryu.]]
* Sasuke from ''VideoGame/SengokuBasara'' acts like this toward his young master Yukimura, being his friend and advisor and protecting him in dangerous situations. He also acts as emotional support and makes sure he toes the line.
* Commander Shepard, the protagonist of ''Franchise/MassEffect'', is this to [[TheLancer Garrus]] [[CowboyCop Vakarian]].
** Shepard also has something of a mentor role to Tali, [[PromotedToLoveInterest at least until the second game.]]
* Guy is this to Luke in ''VideoGame/TalesOfTheAbyss''. He [[spoiler:in his own words, "raised [Luke] from a blank slate to a spoiled, selfish kid"]] and continues to watch out for and offer him advice throughout the game. At one point, he actually DOES punch Luke [[spoiler:when Luke says that he will die in Asch's place at the Tower of Rem]], and the punch is hard enough to knock Luke flat on the floor.
** Occasionally the line gets blurred between whether Guy is an older brother or surrogate guardian to Luke, given both the little attention and affection Luke's own father, the Duke initially shows towards him, as well as Guy assuming responsibility for shortcomings in Luke's character. Usually this is negligible as Van is a more obvious surrogate guardian.
* In ''VideoGame/TalesOfSymphonia'', Lloyd compares Kratos to the big brother he always wishes he had, during one of the sword training scenes. HilariousInHindsight.
* In ''VideoGame/TalesOfVesperia'', protagonist Yuri winds up becoming one for Karol, helping him mature from a CowardlyLion KidSamurai to a true hero.
* ''VideoGame/TearsToTiara2'': Of the big sister variety. The goddess Ashtarte mentors [[TheHero Hamil]].
* ''[[Franchise/ShinMegamiTenseiPersona Persona]]'':
** ''VideoGame/Persona4'' can see the Protagonist acting this way toward Shu Nakajima, Kanji Tatsumi, and Naoki Konishi. The latter two are actually his underclassmen.
** In ''VideoGame/Persona5'', Joker has this dynamic with Shinya Oda, who himself notes halfway through his Confidant that he sees Joker as an older brother. Amusingly, the confidant starts with Shinya acting as a sort of mentor to Joker on how to handle gun fights. This dynamic reverses when Shinya's personal problems come to light, with Joker being there for him to listen and/or offer advice, guiding him through his problems.
* ''VideoGame/FireEmblem'':
** In ''VideoGame/FireEmblemTheBindingBlade'', Klein saw both Dieck and the dead Prince Mildain as such. [[spoiler: In both cases, Klein's supports can potentially have him find his missing "brothers" serving in TheHero Roy's army: Dieck left to not cause the Reglay House trouble, while Mildain took the identity of Elphin to evade the noblemen who wanted him dead.]]
** ''Binding Blade'' prequel ''VideoGame/FireEmblemTheBlazingBlade'' gives us [[BrokenAce Harken]] playing this role to [[NaiveNewcomer Lowen]]. And in the past, [[TeamDad Marcus]] was also this to him.
** In ''VideoGame/FireEmblemTheSacredStones'', you can build this link between [[HotBlooded Ross]] and Gerik, or between [[TeamDad Seth]] and [[NiceGuy Franz]]. [[BadassBookworm Saleh]] is already this to [[ChildMage Ewan.]] [[TheAce Ephraim]]'s supports with his own sister [[LadyOfWar Eirika]] and with [[BadassAdorable Myrrh]] also suggest these dynamics (with what might be bits of IncestSubtext in Eirika's case).
** 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.
* [[GratuitousNinja Shu]] from ''VideoGame/ArcTheLad'' functions as this for Elc in the beginning of the second game. Elc handles most things alone, but when he winds up in a jam, he knows where to go for advice and backup.
* Kyousuke from ''VisualNovel/LittleBusters'' could almost ''define'' this: he's only a year older than the other characters, but he has the sense of competence, charisma, and confidence that makes all of the other Little Busters look up to him. Riki even says early on that he has the air of an older brother and that everyone always listens to what he says. And since what he says normally involves bringing everyone along on wild, fun adventures, they're more than happy to. But if he honestly thinks hurting one of them in the short-term will be better for them in the long run, he will ''definitely'' do it. Reluctantly, but surely.
%%* Kogoro Tenzai serves this to Mii Kouryuuji in ''VideoGame/ProjectXZone''.
* Goro Daimon is this to Kyo Kusanagi in ''VideoGame/TheKingOfFighters''. Kensou sorta plays the role to Bao, too, even [[spoiler: saving his life when the kid almost pulls an HeroicSacrifice.]]
** Both Ralf Jones and Clark Still play the trope in regards to Leona Heidern.
* Lily from ''VideoGame/HometownStory'' is both the actual older sister and the smithing mentor of Cling and Clang, who are quite friendly with her and naturally adress her as "master".
* Sans from ''VideoGame/{{Undertale}}'' is a laid-back, supportive, funny guy who's popular with the residents of his hometown, takes the [[PlayerCharacter Human Child]] out for friendly dinners and conversation on a few occasions, and is protective-bordering-on-overprotective of his younger brother Papyrus's happiness and innocence, who he's always doing little things for behind his back (while playfully ribbing him to his face). The contrastingly passionate and strict-minded Papyrus seems to find his lackadaisical and goofy big brother more pathetic and annoying than cool on principle, but he still loves, trusts, and cares about him as a person, and isn't above the knee-jerk reaction of turning to him when things aren't going his way here and there.
* Jack in ''VideoGame/VampireTheMasqueradeBloodlines'', [[EstablishingCharacterMoment from the first time he opens his mouth]], falls squarely into this role.
-->'''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 ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'', Simon Blackquill has resumed the mentor role he had with Athena Cykes. He stops Prosecutor Nahyuta from bullying her (joining her at the defense bench to do it), but he also grabs her by the shoulders and gives her a shake when she starts to lose faith in her client.
* Early in ''VideoGame/SouthParkTheStickOfTruth'', Both Eric Cartman and Butters Stotch played this role toward the New Kid, giving him advice and guidance in surviving South Park as well as teaching him how the play the fantasy LARP game he gets drafted into playing.
** In ''VideoGame/SouthParkTheFracturedButWhole'', Cartman (as The Coon) mentors the New Kid again, but in a slighty more downplayed fashion. Scott Malkinson (as Captain Diabetes) plays this trope much straighter though.

[[folder:Web Comics]]
* Finas of ''Webcomic/HannaIsNotABoysName'' seems to fit this role with Casimiro. He seems dedicated to trying to keep the impulsive younger vampire out of trouble.
* Noel from ''Webcomic/LeastICouldDo'' is mostly more of a DeadpanSnarker {{Sidekick}}, but he's also a a voice of sanity that counters the main character's {{Psychopathic Manchild}}ness, and on [[http://leasticoulddo.com/comic/20071006 one occasion tried to beat some sense into Rayne.]]
* The Serpent from ''Webcomic/{{HERO}}'', down to the [[http://invisiblecities.comicgenesis.com/167.html jaw-socking]].
* Kel'noz from ''Webcomic/{{Drowtales}}'' is a [[spoiler:[[BigBrotherMentor Uncle]]]] [[BigBrotherMentor Mentor]] to Ariel. More of a standard mentor to the rest of her classmates, though.
* Rita from the ''Webcomic/GiftsOfWanderingIce'' is a sister mentor for her brothers - Rikter and Nikt.
* ''Webcomic/TowerOfGod:'' Rachel to Baam. [[spoiler: [[BrokenPedestal Until stuff happens.]]]]
* Wendy of ''[[Webcomic/CwensQuest Cwen's Quest]]'' is a female version of this trope as well as Cwen's {{Animal Sidekick}} and the good guys' {{Only Sane Man}} though she tends to dead pan snark rather the 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]].
* [[OnlyKnownByTheirNickname Bro]] is Dave's guardian in ''Webcomic/{{Homestuck}}'' in lieu of any parents, and taught him everything he knows, from mixing sick beats to the art of {{irony}} to [[KatanasAreJustBetter the value of katanas]]. [[spoiler: He also gets killed in Act 5.]]

%%* Ferris is Dutch's Big Brother Mentor in ''[[Creator/OlanRogers New Prime]]''.
* 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 in reinforced when it comes to Sparadrap, the Noob guild's own healer [[spoiler:who happens to be Ystos' older but not-too-bright brother]].

[[folder:Western Animation]]
* WesternAnimation/DannyPhantom fulfills the role to his younger OppositeSexClone, Danielle, constantly protecting her whenever she is threatened.
* [[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.
* Huey, the main character of ''WesternAnimation/TheBoondocks'' is an example to his younger brother Riley (and possibly to his ''[[ManChild Granddad]]'' as well). Considering though that Riley is quite the arrogant {{jerkass}}, Huey ends up "educating him the hard way" more often than most Big Brother Mentors.
%%* Aqualad acts like this to Robin and also ComicBook/{{Superboy}} in ''WesternAnimation/YoungJustice''.
%%** As with the comics example, Nightwing to Robin (Tim Drake) in the second season.
%%*** Superman eventually becomes this to Superboy (but it takes a Hell of a long time for it to happen and when it finally does it's off camera via a time skip).
* The Voltron Force, especially Lance, serve as Big Brother/Big Sister mentors to the cadets in ''WesternAnimation/VoltronForce''
* In ''WesternAnimation/ThunderCats2011'', Tygra acts as an interesting combination of this and the TheRival to Lion-O. While he makes no effort to hide how [[TheResenter resentful]] he is of Lion-O's status as TheChosenOne, he's also shown that he'll always have Lion-O's back when he's in trouble and has even given him some support when Lion-O doubted himself.
* Edward from ''WesternAnimation/ThomasTheTankEngine'' serves as one to the younger engines who often are in need of advice like Thomas and Percy and to keep them in line like he does with Bill and Ben.
** Thomas plays as one to the younger engines in the later seasons, most especially with Billy.
** Toby was often this in early episodes to Thomas and Percy. After his [[ShrinkingViolet meekness]] [[{{Flanderization}} took over his personality]], this trait was downplayed or sometimes even reversed, though still pops up every now and then.
* Anakin to Ahsoka in ''WesternAnimation/StarWarsTheCloneWars''. Anakin is not super great at the "Jedi may not have attachments" thing, and so the mentor relationship he has with his Padawan quickly acquires this dynamic.
* The relationship between Scootaloo and Rainbow Dash develops into this in ''WesternAnimation/MyLittlePonyFriendshipIsMagic.'' In the first two seasons, Scootaloo openly admires Rainbow, though Rainbow doesn't take particular notice of her. When [[Recap/MyLittlePonyFriendshipIsMagicS3E6SleeplessInPonyville a third season episode]] has Scootaloo confess she wishes Rainbow would become "like a big sister or something", Rainbow agrees to it. [[Recap/MyLittlePonyFriendshipIsMagicS4E5FlightToTheFinish Their next spotlight episode]] shows how this has developed.

* Naturally, the name of the vounteer organizaton Big Brothers is referring to this concept of mentoring (and of course, the Big Brothers are symbolic brothers rather than literal blood kin).
