* 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.

** 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.]]

In {{anime}}, this kind of character is often [[JapaneseHonorifics addressed]] using the more informal "aniki" instead of "onii-san".

%%* ''Literature/TheHost'': Jared Howe to Jamie Stryder.

In {{anime}}, this kind of character is often [[{{Honorifics}} addressed]] using the more informal "aniki" instead of "onii-san".

** An evil example comes in [[Manga/JojosBizarreAdventureVentoAureo 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.

* 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 Face Heel Turn 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 Heroic BSOD moment.]]

* ''Manga/PokemonAdventures'':
** Green is this to Yellow in her arc.
** A female example would be Crystal to Emerald.

** 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)]].

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

** 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.'']]

* In ''Anime/SpeedRacer'' the mysterious Racer X, who is secretly Speed's older brother Rex Racer, will frequently give Speed advice for upcoming races, warn him of danger, and has saved Speed's life on numerous ocassions. However, he also does his best to win his races against Speed, and Speed sees him as a rival.

* ''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.

** 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 Peter Wisdom a.k.a. [[spoiler: Regulus Black]] in chapter 72 when he realises that Wisdom set Warren up so that he'd end up having to kill someone and would therefore be easier to mould into a soldier.
** Betsy Braddock is noted to be acting as a big sister figure and psychic therapist to Ginny Weasley in the first and second books because Ginny's psychic trauma from the Diary Incident is much more obvious and extensive. The MindRape involved is explicitly compared to the grooming, rape, and attempted murder of a minor by ex-cop Cassidy, while Harry later describes it as being like a boa constrictor crushing her to swallow her whole.
** Jean-Paul Beaubier takes this role, initially to Harry (a little bit), and later rather more extensively to Clark, who's much more of a NaiveNewcomer, who Jean-Paul is correspondingly protective of - it gets to the point where his rationale for keeping Clark away from their superpowered peers is startlingly cold even to the highly protective Jonathan Kent (Harry attracts trouble, therefore Harry attracts attention, therefore if Clark stays away he can fly under the radar until he can protect himself, while all the {{Big Bad}}s will be dealing with Harry). Clark sometimes bridles at this, particularly at Jean-Paul's sometimes selective attitude to the truth.

* In ''[[Fanfic/TheRivalPrefectsTrilogy The New Prefect]]'', Thomas acts as this for Albert, helping him with homework and ensuring that he becomes a prefect. [[spoiler:Although they are physically close in age, Thomas is actually a century older due to being stuck as a statue.]]

* 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.

** 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.

* 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 as he does with Bill and Ben.

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

* 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.

* 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.

*** He also plays this role in prequel ''Anime/MacrossZero''.

** 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]].

** 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 Sanji 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]].

** 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.

* Franchise/GreenLantern: Unlike many of their colleagues in the Franchise/JusticeLeagueOfAmerica, who are typically played as [[ParentalSubstitute Parental Substitutes]] to their their younger allies, Hal, John, and Guy act as big brother mentors to Kyle, Simon, and Jessica.

* 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.

* In ''Fanfic/AmazingFantasy'', Peter acts as a playful, almost brotherly mentor to Izuku, walking him through the motions of being Spider-Man and helping him whenever he stumbles. He's plenty willing to poke fun at Izuku's expense, but he cares deeply about him and his success. At the same time, his fatherly side comes out from time-to-time and he worries that he's using Izuku as a ReplacementGoldfish for his daughter, Mayday.

** The first mentor that Blue Eyes (the hero of the story who is a small tomcat) gains is a stray she-cat Green Eyes. She's kindly and teaches Blue Eyes how to climb trees and other useful things, for example that two-legged creatures are actually called humans. She later becomes distant though.

*** 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 to formally induct Link to the group with a traditional ceremony and later on, Daruk advises Link how to better get along with Zelda.

* 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 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]].

* Lulu from ''WebVideo/CreamHeroes'' becomes this to kittens Toto and Dodo, as they quickly learn all the tricks he uses to steal food or create mischief for Claire. This includes Toto using the hole in the kitchen counter and Dodo copying everything else Lulu does including standing on his hind legs, meowing really loudly and even stealing any food he can get in his mouth.

* WesternAnimation/DannyPhantom fulfills the role to his younger OppositeSexClone, Danielle, constantly protecting her whenever she is threatened.

* 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.

** Mindf*ck as well, in her own way. She whoed Emp that no matter how screwed up she ''thinks'' she is, there are capes out there who make her look like a Golden Age heroine.

** 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 when they were younger.

* 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.

* Nico to Cal in the ''Literature/CalLeandros series.''

* Tonda for ''Literature/{{Krabat}}'', later Krabat for Lobosch. HereWeGoAgain.

* 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.
