History Main / PlanetEater

* The Getter Emperor from ''Manga/GetterRobo'', before it upgraded to a ''galaxy'' eater.

* In ''Franchise/TheElderScrolls'' series, [[EvilGod Alduin]] is the [[DragonsAreDemonic draconic]] BeastOfTheApocalypse and has the title of "World-Eater". It is his divinely mandated duty to "[[TheEndOfTheWorldAsWeKnowIt eat the world]]" at the end of every "kalpa" ([[EternalRecurrence cycle of time]]) so that it can be remade anew. In ''The Seven Fights of the Aldudagga'', he is described as a [[EldritchAbomination titanic monster]] with divine power even beyond that of the [[OurGodsAreDifferent Daedric Princes]]. He is also described as exhaling entire farms out of his nose and dwarfing even the Throat of the World itself.

* Literature/WorldEater reveals black holes to be winged, intergalactic creatures which eat planets, stars and even light.

* The "Doomsday Machine" in the ''Series/StarTrekTheOriginalSeries'' [[Recap/StarTrekS2E6TheDoomsdayMachine episode of the same name]] breaks up planets and devours the chunks as fuel.
* ''Series/StarTrekTheNextGeneration'' had The Great Crystalline Entity, a giant space snowflake that wiped out the landscape and lifeforms of worlds.

* %% The Grey Goo of ''VideoGame/TastyPlanet'' eventually becomes one.

* Cosma from ''WesternAnimation/{{OKKOLetsBeHeroes}}''. Being a self proclaimed foodie as a size changing LizardFolk woman means feasting on entire planets when the mood strikes her, which becomes an issue in one episode.

* In ''VideoGame/{{Stellaris}}'' [[HordeOfAlienLocusts Devouring Swarms]] composed of [[SiliconBasedLife Lithoids]] are known as Terravores and can slowly consume planets, gaining minerals and alloys, but making them gradually smaller and less hospitable. If left unchecked they can ultimately break the planet into pieces, rendering it permanently useless.

* The titular "Doomsday Machine" in the ''Series/StarTrekTheOriginalSeries'' episode broke up planets and devoured the chunks as fuel.

* The Destroyer, the Lord of Darkness and Eater of Worlds threatened to do ExactlyWhatItSaysOnTheTin in the episode "Battlefield" of ''Series/DoctorWho''. [[spoiler: So the Brigadier [[FiveRoundsRapid shot it]].]]
** The Moment, one of the "ultimate weapon[s] of mass destruction" and final work of the ancient inhabitants of Gallifrey, is specifically mentioned as "the galaxy eater" and is how The Doctor originally ended the Time War. [[spoiler: [[RetCon Until he changed his mind]], thanks mostly to Clara for knocking him out of his pity party, with some help from Ten and Eleven.]]
** And the Racnoss (implied, at the very least):
-->'''Doctor:''' The Racnoss are carnivores - omnivores. They devour whole planets.
** The Great Vampires from the Creator/TomBaker era arc "State of Decay", supposedly devoured planets as well.
** The creature from "The Claws Of Axos" drained life-energy from whole planetary ecosystems to sustain itself.
** The stingrays from [[Recap/DoctorWhoS30E15PlanetOfTheDead "Planet of the Dead"]] devour a planet's whole ecosystem, leaving it a desert. Then the swarm flies around the planet faster and faster until their combined mass and velocity open a [[OurWormholesAreDifferent black hole]] through which they travel to their next home/meal.

** There's also Hunger, who was sort of like Galactus, except it fed on ''universes''.

* Then there were the Infinites - beings from beyond the universe who wanted to rearrange the galaxies to 'improve the energy flow of the Multiverse'. To this end, they demolished planets and re-shaped them into the means to move galaxies. The actual demolishing was done by human-sized drones which destroyed everything in sight and used the raw materials to replicate themselves until there was nothing left except the molten core and trillions of drones. The Infinites were pretty appalled when they discovered that planets - which to them are about the size of grains of sand - have tiny beings living on them which can't survive that sort of thing.

* ''Anime/GodzillaPlanetEater'' has King Ghidorah, Godzilla's famous arch-nemesis and the eponymous planet eater in the title. Ghidorah in this continuity is a massive, immortal, indestructable energy being from another dimension that uses gravitational powers to eat planets. Ghidorah devoured many planets over the expanse of time he's been around, and almost succeeds at eating Earth.

* ''Series/StargateSG1'' has the Replicators who, after getting access to a time-dialation device, were able to entirely cover a planet with replicator blocks. Granted, the planet is still there, but it's less of a planet now than a planet-sized mass of replicator blocks.

* ''Series/ReturnOfUltraman'': One episode involves the invasion of Vacummon, a planet-eating space cloud the size of galaxies. [[spoiler: Ultraman Jack eventually defeats Vacummon by destroying its gut from the inside, forcing it to spit out every single planet it has devoured]].

* This theme was revisited in the ''WesternAnimation/StarTrekTheAnimatedSeries'' episode [[Recap/StarTrekTheAnimatedSeriesS1E3OneOfOurPlanetsIsMissing One of Our Planets Is Missing]] where a gaseous antimatter entity the size of a small nebula which arrived from outside the galaxy and began digesting planets. [[spoiler: In a twist on the theme, the entity proved to be sentient, though not particularly bright, and once the ship's crew managed to establish communication and explain that its next intended meal was inhabited by living things, the entity decided that eating inhabited worlds was murder and set out for uninhabited regions.]]

* ''Wiki/SCPFoundation'': There is an SCP capable of this, but most scientists aren't even aware of it. [[spoiler:It's [[http://www.scp-wiki.net/scp-2317 SCP-2317]], and only O5 personnel are fully aware of it. Why? ''There is no way to stop 2317 once it awakens'', with the "containment procedures being just an EmptyPromise to keep from a widespread panic.]]

** To the point that ''to this day,'' some Shi'ar aren't over it. Jean's entire family was slaughtered by the Shi'ar Death Commandos, (during a time Jean was [[DeathIsCheap mostly dead]], so it's Rachel, not Jean, who swears vengeance for the death of her family. Apparently, it didn't occur to them that ''pissing off'' a Phoenix host is a bad idea.) and in ''Phoenix: Endsong'', there was a Shi'ar operative who came to Earth when Phoenix woke up. Even though they know that it's highly unlikely that something like the sequence of events that led to Dark Pheonix could happen again. (Jean is a pretty decent person who almost never has full Phoenix powers, and Dark Phoenix was the result of Mastermind screwing with Phoenix's head for ''months.'' Throw in the ContinuitySnarl retcon soup about how much of Jean was in the original ''Phoenix Saga'' and how much of the Phoenix is in Jean after it. It's not the textbook WithGreatPowerComesGreatInsanity case and it ''certainly'' wasn't Jean's fault.) In universe ''and'' out of it, she's the poster child for NeverLiveItDown.

* The Sun-Eater from ''ComicBook/LegionOfSuperHeroes'', which does ExactlyWhatItSaysOnTheTin.
** Interestingly, the first appearance of something called a Sun-eater was very different from later interpretations, being a fiery giant that new legionnaire of the month "Marvel Lad" [[spoiler: really Mon-el having fun]] took out in one page as part of his initiation test. The sun-eater gained it's much more formidable cloud form later.
** Additionally, ''Legion Lost'' introduced the Omniphagos, which, as the name implies, ate ''everything'', and had to be kept imprisoned or it would eat the ''entire universe''.

* [[https://www.youtube.com/watch?v=JFstPS3-CzY&list=PL76DAF0EBB15A9A5F A]] ''WesternAnimation/GarfieldAndFriends'' MusicalEpisode ended with ComicStrip/{{Garfield}} becoming this - in a possible reference to [[http://www.garfield.com/comics/vault.html?yr=1987&addr=870517 this strip.]]

* The Qualia, from ''VideoGame/ChaosRings'', takes it UpToEleven with the fact that it seeks to destroy [[SpacetimeEater spacetime itself]].

** ''VideoGame/DeadSpace3'' takes this UpToEleven [[spoiler: with the Brethren Moons, Necromorphs the size of '''moons''' that reproduce by consuming all biomass on a given planet's surface.]]

* On June 2022, [[https://www.timeout.com/news/bizarre-news-story-of-the-day-jupiter-apparently-eats-other-planets-062222 a picture from one of NASA's satellites was revealed after the planet’s infamous gases temporarily parted and the chemical make-up of the planet’s core indicates that Jupiter likely swallowed up lots of small planets (called planetesimals) and space rocks to boost its own growth. [[CosmicHorrorStory Which is somewhat horrifying]].

* ''VideoGame/FinalFantasyVII'''s Jenova, who combined the mimetic/assimilation abilities of the creature from ''Film/TheThing1982'' with the retirement plans of [[VideoGame/ChronoTrigger Lavos]]. Much of Jenova's history is kept vague: it was discovered in a glacier near the ruins of the ancient Cetra civilization. It was frozen in the shape of a naked woman, except with missing limbs and numerous alien appendages jutting out from its shoulders and torso. According to lore a "calamity from the sky" came to the planet, imitated human form and nearly wiped us out until a few remaining Cetra buried it in ice. It would have remained dormant but for an excavation team in the present day, who were looking for remnants of the Cetra and assumed that Jenova was a mummy. Eventually, Shinra's scientists took possession of the body and began experimenting on injecting Jenova's undying cells into potential soldiers, which mistakingly allowed Jenova to work its will from inside them. Its ultimate goal is to destroy the planet, then use the hollow shell as a vehicle for preying on other worlds.
** Jenova's motives and nature can actually be summed up pretty easily: It's an infectious agent, not really a life form, that lands on a host planet and subverts it in order to reproduce and spread. In the real world we've got something that behaves in almost the exact same manner: a ''Virus''.

* Byron, and by extension Polidori, from ''[[VideoGame/{{Boktai}} Lunar Knights]]''.

* In ''VideoGame/FinalFantasyIX'', [[spoiler:Terra is a parasitic other planet gradually dining on the souls of Gaia, a planet it has been slowly trying to devour for a very long time]].

* The title of the final chapter of ''VideoGame/FinalFantasyIVTheAfterYears''. The actual event taking place during it is less about eating planets and more about [[spoiler:[[ColonyDrop crashing meteors and the moon into them]]]], though.

* The Grey Goo of ''VideoGame/TastyPlanet'' eventually becomes one.

* The planet Fusion is this in Cartoon Network's ''VideoGame/FusionFall''.

* In ''Videogame/ChaosRingsIII'', The Entity is a massive beast that drains entire worlds of their lifeforce. It is a predator and planets are its prey. [[spoiler:Even worse, it's not a unique creature -- its true reason for visiting Marble Blue was to lay its egg.]]

* The Beast Planet from ''WesternAnimation/ShadowRaiders'' gets along by eating planets. Oddly, it's also an ImplacableMan... [[TheJuggernaut err]], [[GeniusLoci planet]], as it [[strike:survives several]] is completely unfazed by [+ALL+] [[HeroicSacrifice attempts at destruction]], even eating two of the heroes' planets. The Beast also produces a near-endless supply of drones who tend to kill off anyone escaping from the Beast's feeding. [[spoiler: Even in the end, they were completely unable to stop it; they had to sacrifice yet another planet to use its teleport world engine to send the Beast planet far away. [[DownerEnding However, the series ended up closing on Planet Reptizar's doomsday]]...]]

* Black holes, if they get close enough. These are cores of dead stars that have high enough gravitational pull to absorb even light. And they cause spaghettification of everything (including planets) that gets close enough. Their existance is still fairly hotly debated, however.

* Phaaze from the ''VideoGame/MetroidPrime'' subseries is itself [[ThatsNoMoon a living planet]]. However, in a loose reenactment of an Franchise/{{Alien}}'s ''modus operandi'' on a planetary scale, it sends out its offspring [[ColonyDrop in meteorite form]] to corrupt and devour other planets as a means of reproducing.

* From ''Series/DengekiSentaiChangeman'' [[spoiler:[[BigBad Star King Bazoo]] turned out to be this]]
