* A [[DownplayedTrope downplayed]] example at the end of ''Literature/{{Elantris}}: [[spoiler:when Raoden adds the missing chasm line to the gigantic [[RunicMagic Aon Rao]] that the city of Elantris forms, allowing it to start functioning again, a burst of light from the city heals all the corrupted [[OurMagesAreDifferent Elantrians]] and restores their powers. Just in time to fight off the invaders!]]

* ''Fanfic/CheshireMiraculousLadybug'': While Adrien as Misterbug has the Miraculous Cure, Marinette as Cheshire has ''Catastrophe'', an equivalent ability activated when she purifies an Akuma with Cataclysm. But it has the catch that it ''must'' be released soon after Cataclysm, or it will strain Marinette's body.

* At the climax of ''[[Fanfic/RainboomsAndRoyalty The Dashverse]]'' story ''Hot Heads, Cold Hearts, and Nerves of Steel'', when the Elements of Harmony and the Crystal Heart are combined against Sombra, the released energy blast depowers him, cleanses the Crystal Empire of his taint, and [[SealedEvilInACan seals]] his Windigo servants in a crystal cage.
* ''Fanfic/ADiplomaticVisit'': In chapter 11 of the third story, ''Diplomacy Through Schooling'', [[spoiler:Twilight is able to undo the damage done by Tirek, including restoring her school and library, via tapping Time's powers]].
* ''Fanfic/TheEquestrianWindMage'': After the Elements of Harmony destroy [[spoiler:Demise]] once and for all at the end of Season 2, they then unleash one of these, which not only [[BackFromTheDead resurrects]] everyone killed during the Battle of the Crystal Empire, but also [[spoiler:destroys the curse of enslavement Demise long ago placed on the monster races, freeing them all]].

* ''Fanfic/FalloutEquestria'' has The Gardens of Equestria. [[spoiler:Twilight Sparkle's greatest creation, a megaspell powered by the Elements of Harmony able to cleanse all Equestria of all the radiation and taint created by the end of the war and return its ability to be a paradise again.]]
* ''Fanfic/TheKarmaOfLies'' {{Deconstruct|ionFic}}s the usages of this in ''WesternAnimation/MiraculousLadybug'' in various ways:

** After Gabriel is exposed as Hawkmoth, Adrien is honestly shocked to learn that his myriad charges include thousands of counts of murder due to all the people who were killed. (It's mentioned that Syren alone killed thousands when she drowned Paris, and other akumas have body counts as well.) He insists that the charges should be dropped, and that none of those deaths 'count' since everyone was brought back afterwards. His bodyguard [[DisappointedInYou regards him with silent disgust after hearing this argument]], and while Lila backs him up, her internal thoughts reveal that she's only doing so to butter him up.

* In ''Fanfic/APinkPlanet'', Rose Quartzes were created with the express purpose of revitalizing parts of the planet that have been drained through gem creation. While not necessarily fool-proof, a slow and steady pace done in gem-production ensures that life can be reintroduced into a kindergarten with time.

* ''Fanfic/WarAndPeaceInMind'' features one that requires Warren [[AllYourPowersCombined combining]] his HealingHands with [[spoiler:the flames of the Battle Clan, his mother's {{Empath}}ic powers, and Monica's pain-sensing]] in order to heal an entire battleground's worth of badly injured heroes and villains in one fell swoop. However, he's hit by a considerable backlash that [[HeroicRROD knocks him out cold]] for two weeks, along with [[spoiler:leaving him a skeletal, emaciated wreck]].

** Adrien uses the existence of the Miraculous Cure as a self-justification for his SkewedPriorities. After all, everything's going to be magically restored once they win, including anyone who gets hurt or killed, so why does it ''matter'' if he focuses on flirting, cracking jokes and teasing his partner than on fighting akuma?

* In ''Film/StarTrekIITheWrathOfKhan'', the Genesis Device is a World Healing Wave ''weapon''. When fired at a planet, it converts the matter on the surface into life-sustaining matter, in effect terraforming the entire planet in days instead of years. It is shown to have worked on a cave, and in the end, it is detonated in a nebula, building an entire planet from scratch. ''Film/StarTrekIIITheSearchForSpock'', however, shows that it doesn't actually ''work''. Said planet goes through its entire lifecycle (from newly formed planet to catastrophic destruction) in what is implied to be a week or two at most. This because its lead creator, Captain Kirk's son David Marcus, used [[ToxicPhlebotinum unstable protomatter]] in order to basically cheat his way into completing the thing, showing he's not that different from his father.
** The trope is also subverted in that Genesis doesn't discriminate in what it converts. Whether dead rock or populated planet, ''everything'' on the surface is getting culled for Genesis to do its thing. This becomes a big issue in the next few movies because Genesis represented one of the deadliest weapons known to civilization: a weapon that could not only kill all life on a planet but leave a perfectly healthy biosphere behind for whoever did the killing (or at least do the first part when they discovered how unreliable the creation part was). Perhaps even a biosphere ''more suitable'' to the user's needs than the existing one. This is why the Klingon Ambassador in ''Film/StarTrekIVTheVoyageHome'' described it as the "Genesis Weapon", and was paranoid that the Federation intended to use it to wipe out the Klingon Empire. Worse, it may actually work just fine. It was meant for use on ''dead planets,'' not what specks of matter it could pull together from a ''nebula.'' Apples and oranges, only more so. Though shortcuts were taken, (and for a casual fan, there's no knowing where the ExpandedUniverse stands on the matter) from what we got onscreen, a warning label on it that says "actual planet required" may be all that is necessary for the thing to go operational. It would be ''[[WorldWreckingWave very bad]]'' if misused.

* ''WesternAnimation/GravityFalls'': After Bill Cipher is defeated, all the destruction wrought by him and his {{Mooks}} on the titular town is repaired, including [[spoiler:the journals, including pages that had originally been destroyed]].

* ''Fanfic/InfinityTrainBlossomingTrail'': [[spoiler: Un-Chloe's]] death brings with it a massive wave of good fortune and magic. All across the countryside, people's lives are affected for the better; students taking tests suddenly realize the answers they got wrong, people confess their love to each other, athletes win competitions, and Chloe's mom is struck with a sudden burst of inspiration in her art.

* ''Fanfic/TheKarmaOfLies'' {{Decontruct|ionFic}}s the usages of this in ''WesternAnimation/MiraculousLadybug'' in various ways:

** At the same time, Adrien ''also'' believes that he should be finanically compensated for his 'heroics' as Chat Noir, specifically insisting that he needs repayment for all the times he got temporarily killed on duty. Plagg directly points out his {{hypocri|te))cy, but Adrien brushes him aside while insisting "That's different."

* In ''[[https://archiveofourown.org/works/26693095/chapters/83491480 Everything You Deserve]]'', Adrien steals the Earrings and Wishes for a world where he can misuse his Miraculous to his heart's content. He also Wishes for Ladybug to be his slavishly devoted girlfriend. This creates a new reality where he's an infamous ''villain'', and ''Chlo&eacute'' got the Earrings instead, so that he gets [[ExactWords 'Ladybug' as his girlfriend]] without getting what he ''really'' wanted. Chloé is more than happy to abuse the Miraculous Cure in order to wipe away the damage done by their crime sprees. However, when Adrien orders her to ''stop'' restoring and repairing everything, she's [[EveryoneHasStandards deeply shaken]].

* ''VideoGame/TheSaboteur'': Anytime you liberate a Nazi-occupied territory, the region literally poofs from a stormy, gloomy noir mode to suddenly having color.

* In the GoldenEnding of the ''World of Light'' in''VideoGame/SuperSmashBrosUltimate'', killing Galeem and Dharkon at the same time unleashes one. After that, every single spirit goes up in a spire of flame to return to the real world as they wanted.

*** In [[Recap/MyLittlePonyFriendshipIsMagicS8E26SchoolRazePart2 School Raze, Part 2]] The Young Six manage to use the artifacts to foil Cozy Glow's plan and restore magic to Equestria in a big wave of power.

* The ending of ''Anime/GreenLegendRan'' anime results in this. For decades the Earth had been reduced to a wasteland due to an alien influence, and when the BigBad was finally defeated, Ran and his MagicalGirlfriend magically restored the Earth back to what it used to be.
* At the end of ''Anime/RahXephon'', [[spoiler:it is revealed that the instrumentalist can create a world according to their will. Ayato's choice creates a world where all the people he loves are happy, and the Mullian war never happened.]]

* [[spoiler:Massively subverted]] in ''Manga/LegendOfHeavenlySphereShurato''. [[spoiler: The Goddess Vishnu releases one when she's restored to normal after having been TakenForGranite, repairing the Tenkuukai and reviving her fallen Hachibushu warriors. However, it has two drawbacks: she cannot revive Gai due to external influences... and when the one who intervened appears (Shiva, Goddess of Destruction), the Tenkuukai starts ''falling apart again''.]]
* In ''Anime/NarutoTheMovieNinjaClashInTheLandOfSnow,'' the [[MacGuffin hexagonal crystal]] that Princess Koyuki carries around is implanted in a device that causes the [[spoiler: never-ending winter in the Land of Snow to end and spring to arrive.]]

* ''Anime/PuellaMagiMadokaMagicaTheMovieRebellion'' features another one, [[spoiler: this time generated by Homura. If anything, the world it creates is even better than Madoka's - at the expense of it being explicitly under Homura's full control, and by this point, she is pretty much an [[BrokenBird emotionally]]-[[LoveMakesYouEvil shattered]] WellIntentionedExtremist who believes UtopiaJustifiesTheMeans.]]

* ''Anime/JuuniSenshiBakuretsuEtoRanger'': Once the [[MonsterOfTheWeek Jyarei Monster of the Week]] is defeated and purified by the heroes, it transform into a flower that undoes all the damage caused and turning the once FracturedFairyTale back to normal.

* ''ComicBook/TheImmortalThor'': Thor uses the All-Power to summon "the calm before the storm" and repair most of the physical damage from Toranos' attack on New York. Unfortunately, he can't heal the people who were hurt or killed.

* Played with in ''Fanfic/AceCombatTheEquestrianWar''. The Mane Cast [[spoiler: use the Elements of Harmony powered up by Celestia and Luna's magic to slowly rejuvenate Equestria to the state before the war with the griffins]]. However, all characters that died during the war stay dead.

* In ''[[https://archiveofourown.org/works/26693095/chapters/83491480 Everything You Deserve]]'', Adrien wishes for a world where he can misuse his Miraculous to his heart's content, as well as a world where Ladybug is his slavishly loyal girlfriend. This creates a new reality where he's an infamous ''villain'', with ''Chloé'' as his partner, using and abusing the Miraculous Cure to wipe away the damage done by their crime sprees. When Adrien orders her to ''stop'' restoring and repairing everything, she's [[EveryoneHasStandards deeply shaken]].

* At the climax of ''[[Fanfic/RainboomsAndRoyalty The Dashverse]]'' story ''Hot Heads, Cold Hearts, and Nerves of Steel'', when the Elements of Harmony and the Crystal Heart are combined against Sombra, the released energy blast depowers him, cleanses the Crystal Empire of his taint, and [[SealedEvilInACan seals]] his Windigo servants in a crystal cage.
* {{Deconstructed}} in several ways in ''Fanfic/TheKarmaOfLies'':
** Adrien believes that since the [[WesternAnimation/MiraculousLadybug Miraculous Cure]] restores all the damage done by Hawkmoth's akuma, he can goof off during battles to his heart's content. After all, everything's going to be magically restored afterwards, including anyone who gets hurt or killed, so why does it ''matter'' if he spends more time flirting and teasing his partner than fighting?

** After Gabriel is exposed as Hawkmoth, Adrien is honestly shocked to learn that his myriad charges include thousands of counts of murder due to all the people who were killed. (It's mentioned that Syren alone killed thousands when she drowned Paris, and other akumas have body counts as well.) He insists that none of them should ''count'' since they were all brought back. Gorilla [[DisappointedInYou regards him with silent disgust upon hearing this argument]]. Yet he ''also'' believes [[{{Hypocrite}} that he should be compensated for all the times he temporarily died as Chat Noir]]. Plagg directly points this discrepancy out, but Adrien brushes him aside while insisting "that's different."
** When Chat Noir makes the same argument during an interview, he's [[WhatTheHellHero called out on it]] -- the physical consequences may be repaired, but the memories and psychological impact remain. Kagami and Luka point out that both of them have been akumatized ''and'' had to deal with their loved ones being akumatized and coming after them.

* At the end of the [[BadFuture Dark World]] storyline of the ''FanFic/PonyPOVSeries'', [[spoiler:Rarity's [[DeityOfHumanOrigin ascension]] to being [[PhysicalGod Liberalis]], the [[AnthropomorphicPersonification Concept]] of the [[DimensionLord Mortal World]], releases one of these that removes the last of Discord's tainted chaos from the world and restoring harmony]].
** [[spoiler:The use of ''six'' sets of Elements of Harmony to defeat Nightmare Eclipse once and for all lets off a ''timeline healing wave'' that breaks the GroundhogDayLoop she turned the Dark World timeline into and fixes the damage she caused to it.]]

* ''WesternAnimation/ATrollInCentralPark'' has one at the end, with Stanley repairing Central Park after it was destroyed by Gnorga's WorldWreckingWave. But he takes it too far, covering all of New York City in flowers, [[FridgeLogic which would bring one of the most important cities in the world to a screeching halt and have a devastating effect on the ecosystem.]]

* In ''WesternAnimation/CodenameKidsNextDoor WesternAnimation/OperationZERO'', thw world returns to it's bright and sunny state, the KND's Treehouse Bases are reverted back from being tapioca factories, and everyone reverts back from being Senior Citizombies after [[BigBad Grandfather]] has been [[LaserGuidedAmnesia decommissioned]] back into a normal old man.

* ''WesternAnimation/GravityFalls'': After Bill Cipher is defeated, all the destruction wrought by him and his {{Mooks}} is repaired, including [[spoiler:the journals, including pages that had originally been destroyed.]]

* In ''WesternAnimation/TransformersPrime,'' we get the Omega Lock. With the four keys in place, it can create one of these and revive Cybertron. However, Megatron wanted to direct it at Earth and "cyberform" it, overwriting what was already there with a new biosphere suitable for Transformers. Like the ''Franchise/StarTrek'' franchise's Genesis device, the difference between a World-Healing Wave and a WorldWreckingWave can come down to whether or not that world had anything on it beforehand. Optimus was forced to [[spoiler: strike the Omega Lock with the Star Saber, possibly ending any chance of ever reviving Cybertron]]. In the season 3 finale, [[spoiler:a rebuilt but weaker Omega Lock is used to revitalize Cybertron's core. It's technically a world-healing wave, in that it brought the planet back to life, but it isn't powerful enough to fix all the surface damage. Better than nothing, though.]]

* In ''[[https://archiveofourown.org/works/26693095/chapters/83491480 Everything You Deserve]]'', Adrien wishes for a world where he can misuse his Miraculous to his heart's content, as well as a world where Ladybug is his slavishly loyal girlfriend. This creates a new reality where he's an infamous ''villain'', with ''Chloe'' as his partner, using and abusing the Miraculous Cure to wipe away the damage done by their crime sprees. When Adrien orders her to ''stop'' restoring and repairing everything, she's [[EveryoneHasStandards deeply shaken]].
