-> ''He [Elisha] [[TropeNamer took up also the mantle]] of Elijah that fell from him, and went back, and stood by the bank of Jordan;''
-->-- 2nd Kings 2:13, ''Literature/TheBible'' (King James Version)

So you're two thirds of the way through a book/movie/whatever, when suddenly, TheHero /TheLeader/ TheChosenOne etc. dies, is imprisoned, performs a FaceHeelTurn, or is otherwise unable to act as their important role. [[DarkestHour All seems lost]], a TakeUpMySword hasn't been pulled! What is to be done?

But wait! A {{Sidekick}}, the LoveInterest, TheRival, a MauveShirt or even a FriendlyEnemy steps or is forced into this important role, and the work that you are reading focuses on them for the rest of the time it takes to finish the work. Essentially, it's when someone invokes LegacyCharacter.

TakeUpMySword is different in that it implies that the original had time to say something along the lines of ImDyingPleaseTakeMyMacGuffin to his successor, whereas with TakingUpTheMantle, the character has to take the initiative or be shown that it's what they have to do, but ultimately, they have to make the decision themselves.

In so far as it applies to sidekicks, it's a relative to YouAreInCommandNow, which applies to more rigid situations where the Big Hat Of Command lands on a person's head whether they want it to or not, based on their level in the hierarchy.

May or may not be related to and/or overlap with LegacyCharacter, AllUpToYou, YouAreInCommandNow, FieldPromotion, or ItsTheJourneyThatCounts.

The TropeNamer comes from a line in Literature/TheBible where Elisha takes up the mantle of Elijah the prophet -- literally.

Due to the nature of this trope, spoilers are bound to follow.



[[folder:Comic Books]]
* Wally West took up the mantle of ComicBook/TheFlash after his mentor Barry Allen died saving the universe in ''ComicBook/CrisisOnInfiniteEarths''. He is considered to be one of the most successful {{Legacy Character}}s and is the first one among his own generation from Teen Titans.
* After Franchise/{{Batman}}'s [[NotQuiteDead "death"]] during ''ComicBook/FinalCrisis'', [[ComicBook/{{Nightwing}} Dick Grayson]] is forced to become Batman because Bruce Wayne never appointed a successor, and Gotham City was descending into chaos without Batman's presence to strike genuine terror into the hearts of criminals. Dick was reluctant to become Batman because Bruce left specific instructions ''not'' to don the cowl. But Bruce was a bit shortsighted on the matter, so Dick eventually wound up doing so anyway. [[spoiler:Bruce was understanding when he got back.]] Specifically, it comes from the above quote.
** ''Battle for the Cowl'' was about ''several'' people trying to become the new Batman. [[ComicBook/{{Nightwing}} Dick Grayson]], [[Characters/{{Batman}} Tim Drake, Jason Todd, Two-Face]], and Michael Lane, the new ComicBook/{{Azrael}}, all heeded the call to become Gotham City's new Dark Knight. The first two issues of the mini-series, the story mostly focused on Tim Drake, but in the final issue, it mostly focused on [[ComicBook/{{Nightwing}} Dick Grayson]].
** In the first arc of ''Batman, Inc.'', Jiro Osamu steps into the role of his deceased mentor Mr. Unknown to prove himself to Batman. [[spoiler:He succeeds - and is appointed Batman of Japan.]]
** [[Characters/{{Batman}} Tim Drake]], when he was set to become [[LegacyCharacter Robin]], actually had the nerve to don Jason Todd's Robin costume and to go out with Alfred to rescue Batman and ComicBook/{{Nightwing}}. ''And'' he managed to pull it off.
** Briefly attempted by ''Bane'', of all people, when Batman disappears during ''ComicBook/ForeverEvil''. Gotham is in chaos, with Arkham's inmates released, and Bane knows this is the perfect time to conquer the city. He runs into a bit of trouble with the Arkham crew though, and realizes that to succeed he needs to become something that truly terrifies them- so he makes his own Bat-costume and declares himself the new Batman. Note that he has no real intention of being a hero or living up to Batman's ideals; he just needs the fear. Needless to say, his stint ends [[ShaggyDogStory in the space of a couple pages]] once ''Forever Evil'' is resolved and the real Batman can return to Gotham.
* After ''ComicBook/TheDeathOfSuperman'', four heroes appeared on the radar ready to take Franchise/{{Superman}}'s place; the Cyborg Superman, the Eradicator, and Superboy each had an equal stake in the name and his own motives to want to be the Man of Steel. The fourth, Steel, never claimed to ''be'' Superman but followed his example and tried to protect his legacy.
* In ''ComicBook/VForVendetta'', Evey winds up doing this [[spoiler: after V's death]].
* ''ComicBook/UltimateSpiderMan'': After Peter Parker [[spoiler: is killed by [[NotQuiteDead Norman Osborn]]]], a tiny [[TwoferTokenMinority black/hispanic]] kid with Spider-powers named Miles Morales decides to pick up the slack and become Spider-Man.
* In ''Wecomic/TheOrderOfTheStick'': Book -1 ''Start of Darkness'' opens with Redcloak being obliged to pick up the Crimson Mantle of the High Priest Of The Dark One, as the only surviving cleric after a Paladin raid on his village.
* In the ''ComicBook/DarkwingDuck'' comic series, one story line features many Darkwings from alternate universes. One of them had taken up Gosalyn's Quiverwing Quack superhero identity after she was killed performing a HeroicSacrifice in his universe, and [[ILetGwenStacyDie there was nothing he could do to save her]]. Interestingly, the comic has him fight Darkwarrior Duck, the BadFuture version of Darkwing from an episode of the TV show, who thought that ''his'' Gosalyn had run away from home, and had a ''[[KnightTemplar very]]'' [[AllCrimesAreEqual different]] reaction to losing her. [[spoiler:Quiverwing [[CurbStompBattle completely wrecks his ass]].]]

[[folder:Fan Works]]
* In ''[[https://www.fanfiction.net/s/8933408/18/Wizard-Runemaster Wizard Runemaster,]]'' [[TabletopGame/WarcraftTheRoleplayingGame Medivh's ghost]] appears in Karazhan to appoint Literature/HarryPotter as Azeroth's new Guardian.

[[folder:Films -- Animation]]
* ''WesternAnimation/TheTransformersTheMovie'' has Hot Rod spending much of the movie trying to find someone to take over for [[spoiler: Optimus Prime]], only to finally take the mantle of leadership of the Autobots himself and save the day.
* In ''WesternAnimation/TwiceUponATime'', when Synonamess Botch attacks the region of Din, the Fairy Godmother is stretched so thin that she's run out of heroes. Ralph and Mum, incompetent workers desperate to be known, are hired on the spot to stop Botch. [[spoiler:They succeed.]]
* In the 2007 ''WesternAnimation/{{TMNT}}'' movie, [[spoiler:[[TheBigGuy Raphael]]]] briefly takes over for [[TheCaptain Leonardo]] just prior to TheClimax.
* In ''WesternAnimation/{{Megamind}}'', [[spoiler:Megamind himself fills Metro Man's role]].

[[folder:Films -- Live-Action]]
* ''Film/TheDarkKnightRises'' has [[spoiler: Robin John Blake]] do this at the end.

* The short story ''Aftermath'', taking place just two hours after ''Literature/{{Changes}}'' in Literature/TheDresdenFiles, [[spoiler: [[OurHeroIsDead with Harry shot and thrown into Lake Michigan]]]], there is no one to protect Chicago from the supernatural baddies, until [[spoiler: [[BadassNormal Murphy]] and [[OurWerewolvesAreDifferent the Alphas]] take up the charge [[SugarWiki/MomentOfAwesome "untill Dresden gets back."]]]]
* The TropeNamer comes from a line in Literature/TheBible (specifically, the book of 2nd Kings) which states that the prophet Elijah's protégé Elisha literally took up Elijah's mantle after Elijah was taken up into heaven. Elisha was automatically endowed with a significant portion of Elijah's power, and assumed his place as the de facto leader of all of the prophets of {{God}} residing in Israel, as well as becoming one of the greatest prophets ever.
* In the ''Literature/CodexAlera'' series, Tavi is assigned a minor role in the Legions. When a lightning storm kills all of the commanding officers higher than him in rank, he steps in to command the Legion.
* About halfway through ''The Sea Runners'' by Ivan Doig, [[spoiler: Melander]] is killed, forcing [[spoiler: Karlsson]] to take up the role of leader.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': The Scoobies combine their talents and abilities to hunt vampires in Buffy's absence [[spoiler: after her death]]. They don't seem to be very good at it judging from the one occasion we see.
* In ''Series/{{Supernatural}}'', Sam and Dean take up their father's hunting responsibilities after their father disappears, and Garth assumes [[spoiler: Bobby's role after his death]].
* Thematically, this is what is going on all through ''Series/BabylonFive's'' [[PostScriptSeason fifth season]], with the various leads moving on to other roles in life and PassingTheTorch to supporting characters, to show that even with the main cast being broken up, Babylon 5's mission continues.

* This happened once in ''Toys/{{Bionicle}}'', specifically in the third DirectToVideo movie, ''Bionicle 3: Web of Shadows'', when [[FailureKnight Vakama]], the leader of [[TrueCompanions the Toa Metru]], and TheHero of the previous film, performs a FaceHeelTurn about half way through the movie. [[PluckyComicRelief Matau]] steps into the role of TheHero, and wages a successful IKnowYouAreInThereSomewhereFight with Vakama, after which he becomes co-{{Lancer}} with [[TheHeart Nokama]].

[[folder:Video Games]]
* In ''VideoGame/Persona3 [[ExpansionPack FES]]'', when [[RobotGirl Aigis]] gains the "Wild Card" ability, she also gains the "field leader" status from the [[spoiler:[[TheHeroDies recently deceased hero.]] And also gains the role as player character.]] This does cause some resentment from another DesignatedLoveInterest Yukari.
* In ''VideoGame/MassEffect2'', Liara is trying to find the Shadow Broker, an information dealer who is possibly the most powerful individual in the entire galaxy, who hides on a ship drifting inside a storm on an uninhabitable planet and never shows his face to anyone and communicates with his top agents only through digital voice synthesizers. While trying to free Liara's assistant, who has been captured, the Shadow Broker and all his personal guards are killed in his office. After the fight dozens of agents call in to inquire about the disrupted connection.
--> '''[[spoiler:Liara]]:''' This is the Shadow Broker, the situation is under control. We experienced a power fluctuation while upgrading hardware. We are back online, resume standard procedures. [[MeaningfulEcho I want a status report on all operations within the next solar day.]]

* ''WesternAnimation/TronUprising'' begins as the young Program Beck is told by the legendary hero Tron that Beck must be a hero to the programs and fight Clu because Tron was severely injured by Clu and will never fight the same way again.
