History Main / PlanetEater

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

** 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.

* And then there's the Limbo Cell from DC's Elseworld 'Another Nail'; far from being a cheerful sort of dance-prison, this insanely huge being (roughly the size of Earth's orbit around the Sun ''at the narrowest point of its serpentine form'' )was slowly but surely eating all of existence, starting with the more basic forms of energy, moving up to cosmic power, magic and the like and eventually proceeding to matter and ultimately spacetime itself. Adding insult to injury, far from being a villainous predator, the only sensation this practically mindless cosmic amoeba felt was the vaguest inkling of satisfaction at sating its hunger.

PlanetLooters and [[HordeOfAlienLocusts Alien Locusts]] taken to the [=Nth=] degree. Taking ''this'' trope to the Nth degree, is SpacetimeEater. Compare OmnicidalManiac and PlanetaryParasite. This is an X-1 class threat in ApocalypseHow. When a character eats planet-sized portions (or eats so much they're the size of a planet) that's BigEater.

* IDWPublishing ended its long-running Transformers series with ''ComicBook/TheTransformersUnicron'', a GrandFinale driven by the arrival of Unicron. Unlike other incarnations of the Chaos-Bringer (see his entry in Western Animation), this version of Unicron didn't have any cosmic roots, instead being an automated DoomsdayWeapon to wipe out the Cybertronian species as revenge for the ancient Cybertronian empire doing the same to its builders millions of years ago. Shrugging off every attempt to destroy or control it, Unicron consumes thirteen planets over the course of the series (including Cybertron itself), [[TheAssimilator growing larger and stronger]] with each, and is only stopped at Earth when Optimus Prime performs a HeroicSacrifice to merge with its mind and convince its creator to make peace, causing Unicron to implode into a black hole.

* In Creator/JunjiIto's ''Manga/HellstarRemina'', the titular Remina, being an EldritchAbomination, eats the planets of the Solar System on its path. Bonus points for being a planet itself.

* The organisms in the book ''Moonseed'' by Stephen Baxter. "It eats planets. And it's here".

* The [[JerkassGods High Gods]] of the ''Manga/{{Kurohime}}'' universe get their power from draining the LifeEnergy of a planet and [[PlanetLooters taking the dead planet as their bodies.]]

* In ''Franchise/TheElderScrolls'' series, 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.

** And who could forget [[LargeHam "GALACTIMUS! EATER OF ALL PLANETS!"]]

->''"Stan Lee thinks big. He came up with Galactus, a massive purple guy who eats entire planets. That's menacing! To get any more epic in scope, you'd have to have Andromedax, The Galaxy Who Shoots Other Galaxies With A Big, Galaxy-Sized Bazooka. Even better, Galactus isn't some sort of hand-chafing nefarious schemer. He's just very large, very hungry, and loves the great taste of ecospheres."''

* The Leviathan from VideoGame/Destiny2 is a monolithic starship that overshadows the dwarf planet of Nessus, and is actively consuming it -- to mix with "royal nectar" and be formed into [[EatDirtCheap wine]] for the Cabal Emperor's refined palate.

* The AssimilationPlot of ''Film/GuardiansOfTheGVol2Vol2's'' true villain involves him planting a piece of himself (looking like an alien seed or flower bulb) in each planet he wishes to conquer. When he's at full power, those seeds grow to immense size looking and acting like an AdvancingWallOfDoom until they completely consume the planets they're on.

* In ''Literature/{{IT}}'' by Creator/StephenKing, the titular monster claims that it is "the eater of worlds." We're only shown it eating children, but considering what almost happened in the end . . . [[spoiler: It is female and she lays eggs. Hundreds of them. We're lucky for Ben and his cowboy boots.]]

* In ''VideoGame/StarControl 2'', one of the Umgah's pranks is to convince the Spathi of the existence of a "Grand Master Planet Eater".

* Gourmand aliens in ''Franchise/Ben10'' take the meaning behind their name literally, as {{Extreme Omnivore}}s. In ''[[WesternAnimation/Ben10Omnoverse Omniverse]]'' their last-ditch resort in order to repel a hostile AlienOnvasion is to eat their entire planet. And Ben (as his Gourmand form Upchuck) even decides to join in...

* The Leviathan starship from VideoGame/Destiny2 overshadows entire dwarf planets and consumes them -- to mix with "royal nectar" and be formed into wine for the Cabal Emperor's refined palate.

* The World Devastators from the ''Franchise/StarWars'' ExpandedUniverse (specifically, the ''Dark Empire'' comics) are a variation on the Planet Eater concept: [[NighInvulnerability nigh-invulnerable]] machines that tear planets apart with powerful tractor beams, thus mining raw materials to build huge automated fleets of starfighters and, potentially, more World Devastators. While it would take a very long time for a fleet of World Devastators to completely consume a planet, they don't have to eat the whole thing to depopulate it.

** The [[HordeOfAlienLocusts Tyranids]] intend to do this to every planet in the entire ''galaxy''. It's hinted that they're only now encroaching on our galaxy after eating the one they came from and several more along the way.
--->[[MemeticMutation Tyranids! OM NOM NOM NOM!]]
** To be more specific, they don't eat the planets themselves, but they may as well have. Instead, they consume every last scrap of matter that can be converted into biomass to make more Tyranids, as well as draining any oceans and sucking up the atmosphere. Planets worked over by Tyranids still exist, but are nothing more than utterly barren chunks of rock (and those are the ''lucky ones'', since the Tyranids' method of interstellar travel involves telekinetically manipulating a sun's gravity, which often causes it to go nova).
** Some fluff implies that the real reason the Tyranids are doing all of this isn't just hunger but desperate refueling as [[InvadingRefugees they flee something far worse than them.]]
** The World Eaters Traitor Legion are an aversion of this trope. Instead, they are simply AxCrazy.

* The Eldrazi in ''TabletopGame/MagicTheGathering''. Titanic cthonic entities from the [[HyperspaceIsAScaryPlace Blind Eternities between the planes]] that ate whole universes before a trio of Planeswalkers locked them away on Zendikar. The lock...didn't hold.
* ''TabletopGame/DungeonsAndDragons'':
** Draedens, multi-tentacled monsters from the ''[[http://index.rpg.net/display-entry.phtml?mainid=3119 Immortals]]'' boxed set, aren't able to literally devour planets whole, but they're entirely capable of munching a world down to bedrock.
** Gammaroids, great turtle monsters from TabletopGame/{{Spelljammer}}, tend to cause tectonic activity during hatching and then go away, but a big infestation can gradually (over centuries) destroy planets, as happened in Moragspace sphere featured in ''[[http://index.rpg.net/display-entry.phtml?mainid=3546 SJS1: Goblins' Return]]'' module.

* The indie RPG ''Belly of the Beast'' takes place in the digestive tract of one after it scrapes off the surface of a MedievalEuropeanFantasy.

* ''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 it's 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.

* The World Devastators from the ''Franchise/StarWars'' ExpandedUniverse (specifically, the ''Dark Empire'' comics) are a variation on the PlanetEater concept: [[NighInvulnerability nigh-invulnerable]] machines that tear planets apart with powerful tractor beams, thus mining raw materials to build huge automated fleets of starfighters and, potentially, more World Devastators. While it would take a very long time for a fleet of World Devastators to completely consume a planet, they don't have to eat the whole thing to depopulate it.

* The Toronto of ''VideoGame/{{Albion}}'' is another example of man made PlanetEater. It's basically a giant metal colossus that settles on the planet and digs up the surface, while slowly expanding. Eventually it could reduce the entire planet into raw materials.

** The [[HordeOfAlienLocusts Tyranids]] of intend to do this to every planet in the entire ''galaxy''. It's hinted that they're only now encroaching on our galaxy after eating the one they came from and several more along the way.

* 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 mind]], thanks mostly to Clara for knocking him out of his pity party, with some help from Ten and Eleven.]]
