In your world, SantaClaus, TheGrimReaper, the EasterBunny, the Tooth Fairy, or any popular mythical figure actually exists, but something happens which causes them not to be able to actually do their magical duty. Perhaps they fall [[WesternAnimation/TheYearWithoutASantaClaus sick]], possibly they've been [[WesternAnimation/TheNightmareBeforeChristmas kidnapped]], maybe they've [[Film/TheSantaClause died in an accident]] or perhaps the legend wishes to teach someone a [[GodForADay lesson in humility]]. Maybe it's a case of SomeoneHasToDoIt and there is only one who can step in when DeathTakesAHoliday. Who'll step in? You, of course! Subbing for Santa is when the protagonist of a story takes [[GodJob the mantle of a mythical being and takes over their job]], even if it's just temporary.

This is not when a character is infected by a creature and so becomes that creature, like with [[OurVampiresAreDifferent some]] vampires or [[OurWerewolvesAreDifferent some]] werewolves. The mythical task has to be explicitly given or falls upon the protagonists because of the circumstances of them maybe being in the wrong place at the wrong time or maybe because they're the [[TheChosenOne only]] [[SomeoneHasToDoIt one]] who can at that moment.

In the event of an inversion, a character will steal the mantle of the mythical figure in order to reap the benefits or the glory for their own. In such cases, the main characters may need to [[SavingChristmas save Christmas]] or lives, or the world even in order to set things right.

Compare: YouKillItYouBoughtIt, SomeoneHasToDoIt, GodForADay, SavingChristmas and DeathTakesAHoliday. Supertrope to RelievingTheReaper. This trope may also lead to AnAssKickingChristmas.


* Happens during a couple of {{Christmas Episode}}s, of the ''Anime/PrettyCure'' series:
** ''Anime/YesPrettyCure5GoGo'' Apparently, Santa Claus fell off and lost his sleigh, so now the Pretty Cures task themselves to hand out everyone's presents.
** In the world of ''Anime/MahoGirlsPrecure'' many adult magicians take turns being Santa. When the one to do it this year, Issac, hurts his back, guess which three girls decide to take his place....

[[folder:Comic Books]]
* An issue of the ''ComicBook/LooneyTunes'' comic book featured a story where WesternAnimation/BugsBunny and WesternAnimation/DaffyDuck substitute for Santa Claus and one of his reindeer after the latter injures them.
* The Grim Reaper is replaced by an impertinent little upstart in issue #9 of ''ComicBook/BillAndTedsExcellentComicBook''.
* Inverted in ''ComicBook/TheSmurfs'' story "Little Peter's Christmas", as Gargamel puts Santa Claus to sleep and dresses up as him so that he could infiltrate the Smurf Village. Some Smurfs get the real Santa awake and back on his feet to stop Gargamel as the fake Santa.
* There's one issue of the Creator/MarvelComics series ''What The...?!'' where Santa ends up triggering one of SelfDemonstrating/DoctorDoom's traps and, injured, begs Doom to finish Christmas for him while he recovers in exchange for his heart's desire. In a heartwarming moment, an accidental battle between Doom, ComicBook/TheAvengers, ComicBook/FantasticFour and Speedball ends up bringing them to a hospital for sickly children, where the gathered characters act in the spirit of giving and help the children. [[spoiler:Doom doesn't get his heart's desire because those children loving him unconditionally was that desire, as he's seen at the end, cuddling the teddy of the girl who spotted them.]]

[[folder:Films -- Animation]]
* Several Christmas specials have the protagonist having to fill-in for an indisposed or sick St. Nick, like in ''WesternAnimation/TheYearWithoutASantaClaus''.
* An inversion occurs with ''WesternAnimation/TheNightmareBeforeChristmas'': The King of Halloween, Jack, wishes to take over the job for Santa, so has him kidnapped. Despite his good intentions, Jack forcefully takes Santa's mantle and the entire Holiday.
* ''WesternAnimation/RiseOfTheGuardians'' has an interesting twist where Santa, the Sandman, the Easter Bunny, and Jack Frost all pitch in to help the Tooth Fairy, since the Boogeyman kidnapped her army of smaller tooth fairies who normally do the job.
* ''WesternAnimation/OliveTheOtherReindeer'': A variation. Olive takes over for one of the reindeer after he breaks his leg.
* ''Merry Madagascar'': The cast of ''WesternAnimation/{{Madagascar}}'' has to deliver the presents after Santa comes down with a case of EasyAmnesia.
* Snow Miser and Heat Miser are forced to fill in for Santa after their older brother North Wind breaks his back in ''A Miser Brothers Christmas'', a sequel of sorts to ''WesternAnimation/TheYearWithoutASantaClaus.''

[[folder:Films -- Live-Action]]
* In ''Film/FredClaus'' Fred temporarily taks his brother's mantle.
* ''Film/BruceAlmighty''
** Jim Carrey's character is [[GodForADay given the powers of the Christian God]] in order to teach him a lesson in humility.
** In its sequel ''Film/EvanAlmighty'', Steve Carrell's character is bestowed the fantastic non-powers of Noah. [[spoiler:He can make a boat and animals like him!]]
* ''Film/TheSantaClause'' movie and its follow-up films:
** In the first film, the Santa Sub is Scott Calvin for, well, [[CaptainObvious Santa Claus.]]
** In the first sequel, the Santa Sub is Principal Newman in that she must become the new Mrs. Claus, through a [[IncrediblyLamePun Mrs. Clause.]] binding magical contract.
** The third film has an inversion in that Jack Frost becomes Santa by tricking Scott Calvin into giving up the role.
* The ''Film/ToothFairy'' film with Dwayne Johnson.
* Like the above movie, ''Film/{{Toothless}}'' has Kirstie Alley's character take up the mantle of ToothFairy when she goes to Limbo. Other beings you have to become in Limbo include SantaClaus, EasterBunny, Cupid, Literature/{{Cinderella}}, a [[ThingsThatGoBumpInTheNight Boogeyman]], and Literature/SleepingBeauty.
* In ''Film/PiratesOfTheCaribbeanAtWorldsEnd'', [[spoiler:Will takes over for Davy Jones, who guides the souls of the dead to the afterlife.]]
* ''Film/SantaBaby'': Santa's daughter takes the reign.
* The plot of ''WesternAnimation/TheFairlyOddparents''[='=] second live-action film, ''Film/AFairlyOddChristmas'', also appears to be using this trope.

* This is a staple of the [[TheGrimReaper Death-centric]] ''Literature/{{Discworld}}'' books.
** In ''Discworld/{{Mort}}'', Death takes an apprentice who has to substitute for him when he wanders off to go soul-searching.
** In ''Discworld/SoulMusic'', Death goes missing, and Susan has to temporarily take his place.
** In ''Discworld/{{Hogfather}}'', the [[SantaClaus Hogfather]] goes missing on [[YouMeanXmas Hogswatchnight]], and Death has to temporarily take his place.
** Another example from ''Hogfather'' -- when Bilious was embarrassed to admit to being the [[OddJobGods Oh God of Hangovers]] he made up a story about how he does this on a professional basis, substituting for any deity that needs time off.
* In the ''Literature/PercyJacksonAndTheOlympians'' book ''The Titan's Curse'', [[spoiler:Atlas forces both Annabeth Chase and the goddess Artemis into holding up the sky for him]] so he can lead the Titan army. [[spoiler: Percy Jackson then temporarily takes the sky from Artemis so she can fight Atlas]].
* In ''Literature/ColdDays'' from ''Literature/TheDresdenFiles'', [[spoiler:the Erlking]] allows Harry to defeat him so that Harry can lead the [[spoiler:Wild Hunt]] against the Outsiders.
* In ''How Murray Saved Christmas'' by Mike Reiss & David Catrow, deli owner Murray reluctantly fills in when a [[ExtendoBoxingGlove Jack-in-the-Boxer]] knocks Santa out cold.

[[folder:Live-Action TV]]
* One or two episodes of ''Series/SabrinaTheTeenageWitch'' has the title character delivering presents at Christmas time. And one time Sabrina takes a local Sandman duty as a summer job.
* ''Series/SaturdayNightLive'': "The Night Hanukkah Harry Saved Christmas." Santa is sick so Hanukkah Harry steps in to help out. In a sequel he and the Prophet Elijah step in for the Easter Bunny after the bunny gets caught in a steel trap.
* ''Series/{{Charmed}}''
** When Piper became the [[TheGrimReaper Angel of Death]].
** Paige was once turned into a nymph to replace one that just died.
** ''Charmed'' also had many inversions of demons and warlocks and other bad guys stealing the powers of good magical creatures for their own gain. Just to name a few:
*** A Demon steals Cupid's ring and starts breaking up relationships in revenge.
*** A warlock steals a ring which allowed him to harness the powers of Muses.
*** A warlock stole the powers of a Whitelighter in order to get into heaven and kill all the elders.
*** A demon once used a Sandman's dust in order to bring the Charmed One's dreams to life.
* Dean becomes Death in an episode of ''Series/{{Supernatural}}'', as part of a deal. He finds he can't go through with seeing all the people dying.
* ''Series/TheTwilightZone'''s "The Night of the Meek" deals with a santa example.

* Played with in the ''Franchise/StarWars'' ConceptAlbum, ''Christmas in the Stars''. C-3PO and R2-D2 anxiously await Santa Claus' coming, only to be shocked when the one who actually delivers their presents turns out to be his son, "S. Claus". S. Claus explains to them that Santa couldn't possibly deliver all the gifts in the galaxy, so he has his family assist in delivering them.

[[folder:Myths & Religion]]
* Sometimes in Myth/GreekMythology, a tragic hero or demi-god like Heracles would temporarily take the mantle of another god. Like Hercules being tricked into holding up the sky by Atlas or Phaeton taking the chariot reigns from his father, Helios. While Atlas was never indisposed, Hercules needed a god to pick the apples of the Hesperides because as part mortal he couldn't. So Herc offered to switch places temporarily with Atlas. Herc had to think quickly when Atlas almost bailed on him.

* A [[HolidayMode continued theme]] each [[ChristmasEpisode Christmas]] in ''VideoGame/FateGrandOrder'' is how the [[EvilTwin Alter Servants]] dons the role of Santa Claus and HilarityEnsues. Though there are lessons hidden in the humor. These Alters even have a new Class out of it.
* Helping deliver presents is also a Christmas, or rather, [[YouMeanXmas Frostval]] event in the ''VideoGame/AdventureQuest'' franchise.

[[folder: Webcomics]]
* A standard Easter bit in ''Webcomic/KevinAndKell'' was characters - not necessarily rabbits - subbing for the Easter Bunny. Rudy and Fiona ended up taking on the role full-time, despite being a wolf and a fox.

[[folder:Western Animation]]
* ''WesternAnimation/FamilyGuy''
** Peter takes over as [[TheGrimReaper Death]] when he twists his ankle.
** Brian and Stewie sub for Santa when they discover that all the deliveries are killing him. HilarityEnsues. The events that play out can be viewed as a {{Deconstruction}} of this trope, if not the entire concept of Santa Claus in general. [[spoiler: However, it does do a heartwarming {{Reconstruction}} by the end of the episode.]]
* In an episode of ''WesternAnimation/ThePowerpuffGirls'', the title trio try to stop the villian Princess Morebucks from taking everyone's presents Santa delivered, and thus ruining Christmas. They stop her later, but damage is already done, and there isn't enough time for Santa to deliver the presents by morning. The solution? Have the super fast Powerpuff Girls deliver them!
* An episode of ''WesternAnimation/JohnnyBravo'' has Johnny having to deliver the gifts after he attacked and beat up Santa, mistaking him for a burglar.
* ''WesternAnimation/TheFlintstones''
** In a Christmas special (yes, prehistoric cavemen [[AnachronismStew celebrate Christmas]]) centered around Fred filling in for Santa with Barney helping as an elf. In this case, Santa has a leg injury and has to stay at Fred's house, but maintains radio contact with the sleigh when the two need advice.
** In an actual show episode, Fred's been working as a Santa's helper at Macyrock's department store. He takes a nap at quitting time and is waked by elves who ask him to take Santa's place while Santa has a bad cold. (This would seem to indicate it was AllJustADream but the rest of the episode is played straight.) At the end Fred realizes he hasn't any gifts left for his own family, only to hear sleigh bells overhead and "Merry Christmas, Fred! Aaaa-choo!"
* In the ''WesternAnimation/JackieChanAdventures'' Christmas Episode, Santa is kidnapped by the Big Bad and Tohru has to fill in for the night. Jade and Paco join him as elves, keeping them out of trouble, for once. Played straight again in the third season of the series. When the 12 Talismans of the Chinese Zodiac are destroyed, the powers fall onto one 12 of the actual animals.
* ''WesternAnimation/PhineasAndFerb'': Due to Doofenshmirtz' Naughtyinator, Santa won't be visiting Danville to deliver gifts, so Phineas, Ferb, and company decide to deliver the presents themselves. Subverted at the end. [[spoiler: Santa knew what was going on all along. In fact, ''he set up the whole thing'', because he knew that Phineas wanted to try this.]]
* Disney's ''WesternAnimation/{{Hercules}}'' did this quite a few times where Herc had to sub for quite a few gods, such as driving Apollo's chariot, or covering the land with Morpheus' blanket of sleep.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy''
** More an example of Switching with Santa, in one episode Grim and Billy switch lives for a day, leading to Billy taking over as TheGrimReaper and, [[CaptainObvious well]], HilarityEnsues
** The Grim Reaper being a job in ''TGAOBAM'', other people can take that job. In the Movie, Grim is fired, and is replaced by [[WesternAnimation/CodenameKidsNextDoor Numbuh Three]], before he gets his job back.
* On one of ''WesternAnimation/TheSimpsons''[='s=] Treehouse of Horror shorts, Homer takes Death's mantle after death has a mishap.
* In the ''WesternAnimation/{{Futurama}}'' episode "A Tale Of Two Santas", Bender has to take the place of [[BadSanta Robot Santa]] in an effort by Fry to make a much jollier Xmas for everyone. The problem is everyone still thinks he's evil.
* In the ''WesternAnimation/LooneyTunes'' short "Easter Yeggs", it turns out the Easter Bunny always gets some poor schlub to do his deliveries for him, and this year's schlub is WesternAnimation/BugsBunny.
* In ''[[WesternAnimation/AdventuresOfSonicTheHedgehog Sonic Christmas Blast]]'', both Sonic AND Robotnik pulls this off -- Robotnik forcing the kids to give ''him'' toys and Sonic rescuing, then being promoted to the Santa of Mobius!
* The first ''[[WesternAnimation/TheFairlyOddparents Fairly Oddparents]]'' ChristmasEpisode ends with Timmy, Cosmo, Wanda, and the holiday mascots having to deliver Santa's presents while Santa takes a vacation in Hawaii.
* In the ''WesternAnimation/ChalkZone'' Christmas episode "When Santas Collide", Rudy takes over for Santa #8 (due to the amount of Santas that kids draw near Christmas, [=ChalkZone=] has eight santas) after he gets frozen solid, and has to deliver presents along with Snap to various areas of [=ChalkZone=].
* ''WesternAnimation/HowMurraySavedChristmas'': Murray is coaxed into it after one of the elves accidentally knocks out Santa and he's the only one capable enough to do the job.
* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "Holly Jolly Jimmy", Jimmy brings his friends to the North Pole and zaps Santa with his invention, scrambling his atoms. After being told Christmas has to be called off, Jimmy (who doesn't believe in Santa) offers to deliver all the toys with his rocket, claiming that if a mere mortal can succeed in delivering all the toys in one night, it's proof that Santa doesn't exist. He fails before he can get to Retroville, and Santa, who has gotten better, steps in at the last moment to finish the job.
* The ''WesternAnimation/BumpInTheNight'' Christmas special "Twas the Night Before Bumpy" features a rare example of this being done unintentionally. Mr. Bumpy steals Santa's bag of presents purely for his own personal gain (he later learns the importance of giving), but during his escape from the North Pole's elves, he ends up accidentally dropping the presents down everyone's chimneys. He even put on a Santa hat before he left.
* The ''WesternAnimation/{{Bonkers}}'' episode "Miracle on the 34th Precinct" had Lucky Piquel tasked with filling in for Santa Claus after he went missing while Bonkers searched for the real Santa.
* The ''WesternAnimation/WackyRaces2017'' episode "Dashing Thru the Snow" had Santa Claus put out of commission, forcing Peter Perfect, Penelope Pitstop, I.Q. Ickley, the Gruesome Twosome, Dick Dastardly, and Muttley to do his job in delivering presents. They all mess up, but Santa fortunately recovers in time to fix everything.
* The ''WesternAnimation/MyLifeAsATeenageRobot'' episode "A Robot for All Seasons" begins with Jenny covering for Santa while he's in a full-body cast.
* In the ''WesternAnimation/HiHiPuffyAmiYumi'' episode "Tooth Decay", Ami and Yumi have to fill in for the tooth fairy after Yumi accidentally injures him.
