->''"[[RuleofTwo Always two there are]], no more, no less - a master and an apprentice"''
-->-- '''Yoda''', ''Franchise/StarWars: Film/ThePhantomMenace'', on the [[TheDarkSide Sith]].

A variant of OddCouple featuring an older veteran character, and a younger novice. Often the former is a RetiredBadass who is somehow [[BroughtDownToNormal rendered powerless]] (or just [[ObsoleteMentor helpless against current threats]]) and has to rely on [[YoungGun a newbie]], who happened to be around and accidentally shows a lot of promise, so he [[{{Mentors}} tutors him]].

Perfect setup for RedOniBlueOni - the HotBlooded younger character is kept in check by their OlderAndWiser {{Mentor}}.

If they're cops, this is OldCopYoungCop. If they're father and son, see BadassFamily. If they happen to be a gay male couple, see LoverAndBeloved, and if heterosexual, see MentorShip. With magic users, see MerlinAndNimue.

See also SempaiKohai. MasterApprenticeChain is when this trope is recursed over several generations.

!!Examples

[[foldercontrol]]

[[folder: Anime and Manga ]]

* [[BadassNormal Mireille]] and [[ExtraordinarilyEmpoweredGirl Kirika]] from ''Anime/{{Noir}}''.
* Manga/{{Bleach}} starts out like this, with Rukia losing her shinigami powers to Ichigo.
* The first season of ''Anime/MagicalGirlLyricalNanoha'', with [[QuicklyDemotedLeader Yuuno getting injured and going]] [[MentorMascot ferret mode]] to recuperate, requiring him to rely on the then ordinary elementary school student Nanoha. Except that Nanoha completely overshadows him in a few eps.
** The [=StarS=] and Lightning Teams in ''[[Anime/MagicalGirlLyricalNanohaStrikerS StrikerS]]'' consisted of ''two'' experienced instructors and two students. However, Vita is the only instructor to help the students during the missions, and Nanoha and Fate end up situations where they are rescued by their students in the GrandFinale.
** In ''Manga/MagicalGirlLyricalNanohaViVid'', "Riot Force 6 Instructor (Nanoha) and Student (Erio) vs. Fate".
* Robin Mask and his disciple Warsman form the Choujin Master/Student Combo in ''{{Kinnikuman}}'''s Dream Tag Team Touranment arc. Though the two are on more equal footing than most examples.
* ''HistorysStrongestDiscipleKenichi'': When ever Kenichi gets thrown into one of these with any of his masters (and it happens a lot), it's not because he's needed, its because the masters [[TrainingFromHell want to train]] him by having him fight their opponents' disciple.
* ''Anime/PuellaMagiMadokaMagica'': Across its various spin-offs [[spoiler: and timelines]] Mami has been the master to three different students: Kyouko, Sayaka in ''A Different Story'' and [[spoiler: Madoka in the main series' original timeline.]] She taught each one the basics of MagicalGirl life and fought alongside them against witches.

[[folder: Comics ]]

* Franchise/{{Batman}} and Comicbook/{{Robin}}.
* GreenArrow and Speedy.

[[/folder]]

[[folder: Film ]]

* J and K from ''Film/MenInBlack''.
* Both the Jedi and the Sith in ''Franchise/StarWars'' tend to work in teams like this such as Qui-Gon/Obi-Wan, Obi-Wan/Anakin, Obi-Wan/Luke, Sidious/Maul and Sidious/Vader.
* T.J. and Principal Prickly in ''WesternAnimation/RecessSchoolsOut''
* Buffy and her Watcher Merrick ''Film/BuffyTheVampireSlayer''.

[[/folder]]

[[folder: Literature ]]

* Numair and Daine in ''Literature/TheImmortals'' quartet. Then she gets HotForTeacher.
* OlderThanFeudalism: Elijah and Elisha in ''Literature/TheBible''.
** Also Paul and Timothy
* Vimes and his younger self in the ''Literature/{{Discworld}}'' novel ''Discworld/NightWatch''.
** Lu-Tze and Lobsang in ''Discworld/ThiefOfTime''.
** Granny Weatherwax and Tiffany in ''Discworld/AHatFullOfSky''. Nanny Ogg and Tiffany in ''Discworld/{{Wintersmith}}''. Interestingly, not Tiffany's official witchcraft teachers, who are helpful, but don't exactly fit the trope. Other times the witches fall into TheHecateSisters ensemble.
* That's what happens with Aahz (who is BroughtDownToNormal mage) and Skeeve (who learns magic from him) in ''MythAdventures'' by Robert Asprin.
* Remo and Chiun from ''TheDestroyer''.

* Will (student) and Halt (master) from ''Literature/TheRangersApprentice'' novels.

[[/folder]]

[[folder: Live Action TV ]]

* ''Series/DoctorWho'': The Doctor and his companions, although less so with the reboot's tendency for younger ([[ReallySevenHundredYearsOld -looking]]) Doctors. Also, there's never any suggestion of them filling his shoes, [[WeAreAsMayflies for obvious reasons]].
** With a few almost exceptions - Romana leaves to serve a similar role in another universe, while the never completed plot arcs '''may''' have had Ace eventually becoming a Time Lord. Sarah Jane also gained a similar role in her [[Series/TheSarahJaneAdventures own spin-off]], complete with apprentices of her own.
* A staple of ''Series/{{Highlander}}'', where veteran immortals would train newborns.
* The MST3k episodes "Master Ninja" and "Master Ninja II" feature a team like this, in the form of Lee Van Cleef and Timothy Van Patten, as does "The Master," the TV show from which the movies were hastily spliced.
* ''Franchise/PowerRangers'' sometimes uses a team version, where the Mentor suits up and takes the field with his students as a SixthRanger. Mentors that have done this include [[Series/PowerRangersDinoThunder Dr. Tommy Oliver]], [[Series/PowerRangersSPD Commander Cruger]], [[Series/PowerRangersMysticForce Daggeron (and Udonna and Leanbow on occasion)]], and [[Series/PowerRangersJungleFury RJ]].
* ''KickinIt'': Jack and Rudy entered a tournament where each team had to be this.
* Buffy and Giles in ''Series/BuffyTheVampireSlayer'', the television adaptation of the film mentioned above. The job of a Watcher is to train and look after The Slayer, though the Watcher doesn't always engage in combat.

[[/folder]]

[[folder: Video Games ]]

* Kreia and YOU in ''VideoGame/KnightsOfTheOldRepublicIITheSithLords''.
* In ''VideoGame/StarWarsTheOldRepublic'', if you play as either a Jedi or a Sith (regardless of the class), one of your companions will be your apprentice. Sith Inquisitors get two of them: the Light Side-leaning Ashara and the very Dark-Sided Xalek.
* In ''{{Suikoden}}'', the hero's mentor is one of the LoadsAndLoadsOfCharacters you can recruit. They can even do a CombinationAttack called "Master-Pupil Attack", where they beat up every enemy on screen together.
* ''Franchise/{{Disgaea}}'' has an entire mechanic where characters can serve as mentors to other characters they were used to create with useful advantages for both (for example masters can use the skills of any apprentices that are nearby).
* The Kung Fu chapter of ''LiveALive'' has the master and his surviving student seeking revenge together.

[[/folder]]

[[folder: Visual Novel ]]

* In a similar vein would be ''VisualNovel/{{Tsukihime}}'' where we have Arcueid The Ultimate Vampire Hunter who loses her powers and has to rely on OrdinaryHighSchoolStudent Shiki, who just happens to have the Ultimate Evil Eyes.

[[/folder]]

[[folder: Western Animation ]]

* ''WesternAnimation/BatmanBeyond'': [[TwentyMinutesIntoTheFuture Years after Bruce's retirement]], he meets Terry, who he trains to become the new Batman.
* Zuko and Iroh from ''WesternAnimation/AvatarTheLastAirbender,'' also counts as BadassFamily.
* ''WesternAnimation/StarWarsTheCloneWars'' has Anakin/Ahsoka on the good side, and [[spoiler:Darth Maul]]/Savage Opress on the evil side.
