* 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.

* ''Musketeer Space:'' all three of the Musketeers develop this towards Dana, but especially Athos. He teaches her swordplay, delivers advice (mostly of the "love is for idiots and pretty people aren't to be trusted" variety), petitions for her to be made a full Musketeer and passes on his wealth of knowledge about where to get into the best bar fights.

* 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.

** [[ComicBook/{{Nightwing}} Richard "Dick" Grayson]] decided early on to take a more active role in the mentoring of the third Robin, [[ComicBook/Robin1993 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 [[CasualDangerDialogue 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 believe 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'', [[ComicBook/{{Oracle}} Barbara Gordon]] -the original ''Comicbook/{{Batgirl}}''- helped and mentored Stephanie Brown, who was determined to take up the title and the Batgirl mantle.

* ''ComicBook/SpiderMan'': Spidey tends to act like this for the younger heroes, especially those who feel they can't really trust the adult superheroes. A large reason is that Spidey started his superheroics at their age so he can relate to the struggles of balancing superheroism and teenage life. As a result, a lot 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 a former teenage superhero.]]

** 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.

* In the ''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.

** Pre-Crisis, Diana acted as this to [[ComicBook/WonderGirl Donna Troy]], who was literally her adopted sister. Post-Crisis, the two eventually came to view one another as sisters, but Donna was never raised by Hippolyta or mentored by Diana in that continuity, making this trope no longer applicable.
** Much like the Batman / Nightwing / Robin relationship above, however, Donna did serve as an older sister to Cassie Sandsmark, the second Wonder Girl, until Flashpoint.

** ComicBook/{{Wolverine}} to practically any younger female character. Most notably {{Kid Sidekick}}s ComicBook/{{Jubilee|MarvelComics}} and ComicBook/KittyPryde. 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|MarvelComics}} 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. Played straighter with Gambit's relationship with kid Storm and Jubilee.

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

* 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 and sister's welfare than their parents ever have, and tried to help them with their problems.
* 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.

* 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.

* In [[https://www.deviantart.com/slifofinadragon/ SilfofinaDragon]]'s ''VideoGame/SengokuBasara'' fanfics, UsefulNotes/SarutobiSasuke acts this way towards not just UsefulNotes/SanadaYukimura, but to also [[MisterSeahorse his]] (Yukimura's) grandson Tsukitora (mothered by their son Masa).

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

* Due to the nature of its "legacy" focus on characters, these pop up quite often in Franchise/TheDCU.
* Franchise/{{Batman}}:

* 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 "ComicBook/{{Impulse}} / Kid Flash" Allen (who's technically his cousin, once removed).
* Franchise/WonderWoman:
** Pre-Crisis, Diana acted as this to [[ComicBook/WonderGirl Donna Troy]], who was literally her adopted sister. Post-Crisis, the two eventually came to view one another as sisters, but Donna was never raised by Hippolyta or mentored by Diana in that continuity, making this trope no longer applicable.
** Much like the Batman / Nightwing / Robin relationship above, however, Donna did serve as an older sister to Cassie Sandsmark, the second Wonder Girl, until Flashpoint.
* Franchise/{{Superman}}:

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

** 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. Played straighter with Gambit's relationship with kid Storm and Jubilee.
** 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.
** Mindf*ck as well, in her own way. She showed 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.
* 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, a lot 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.]]
* [[ComicBook/GreenArrow Arsenal]] attempted to be one to teen hero Damage the second time they were with the [[ComicBook/TeenTitans Titans]]. Roy nominated Grant for membership to make up for how things went during Roy's tenure as Titans leader. It was during this time Roy and his daughter Lian were able to help Grant address the severe sexual abuse he'd endured at the hands of his foster father. Roy then offered to bring Grant to the reservation Roy grew up on, so Grant would have a safe place to deal with these emotions without being judged. This desire to help the younger Titan stemmed from abandonment issues Roy endured back when he was growing up with Green Arrow and had grown savvy enough to ''not'' do what his mentor did.

* Another female example in ''Fanfic/AceOfSpades'' where [[Franchise/{{Batman}} Harley Quinn]] is this to Literature/HarryPotter.

** [[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 [[CasualDangerDialogue while blindfolded, fighting bad guys, on a moving train]]).

* ''VideoGame/SonicTheHedgehog'' to [[KidSidekick Tails]]. He's always supportive of him, and helped Tails overcome his timidness and insecurities after this one was [[AllOfTheOtherReindeer bullied during his early childhood by his peers]] for his twin tails and [[GadgeteerGenius dorkiness]].

* As Setsuna's [[SenpaiKohai 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 SenpaiKohai 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.)

* Harvey Specter to Mike Ross in ''Series/{{Suits}}''. After [[BrilliantButLazy Mike]] impresses [[TheAce Harvey]] with his intelligence and eidetic memory, Harvey helps him con his way into a job as a lawyer at Harvey's firm despite Mike having never been to law school. Following this, Harvey begins protecting and mentoring Mike as his protégé, and while this is initially self-serving, as Mike getting caught would lead to Harvey getting disbarred as well, he quickly develops a genuine BigBrotherInstinct for Mike and gets personally invested in him succeeding.

* In ''WesternAnimation/SpiderManAcrossTheSpiderVerse'', [[TheQuincyPunk Spider-Punk]] has this dynamic with Spider-Gwen & ComicBook/SpiderManIndia2023, and initiates this bond with Miles as well.
