->''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.''
-->-- LoreSjoberg, ''[[http://www.bookofratings.com/ The Book of Ratings]]'', "[[http://www.bookofratings.com/marvelvillainsrating.html Marvel Supervillains (Part I)]]"

This is [[ApocalypseHow the way the world ends]], not with a [[EarthShatteringKaboom bang]], but a ''nom'' ([[Literature/TheWasteLand all apologies]] to Creator/TSEliot).

A character that not just destroys but ''eats'' planets for nourishment. They may suck the life-force from the biosphere, feed off its gravitic potential or magnetic field, or just start taking big bites out of the crust and mantle.

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.

[[JustForFun/LousyAlternateTitles This would have been called]] "[[IncrediblyLamePun World Hunger]]", but [[DudeNotFunny that's a real life problem with real life consequences.]] [[EvenEvilHasStandards We guess]].

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''Anime/CatSoup'': The Magician (who may or may not be God) was trying to eat the Earth.
* The [[ThatsNoMoon Big Gete Star]] in the ''Anime/DragonBallZ'' Movie "The Return of Cooler".
* The Getter Emperor from ''Anime/GetterRobo'', before it upgraded to a ''galaxy'' eater.
* In JunjiIto's ''Manga/HellstarRemina'', the titular Remina, being an EldritchAbomination, eats the planets of the Solar System on its way to Earth. Then, it eats the Earth. Bonus points for being a planet itself.
* The monstrous plant Kaiba from the anime series ''Anime/{{Kaiba}}'' consumes planets in addition to the memories of their inhabitants. At least two characters think this is a good thing, viewing it as a form of {{Instrumentality}}.
* 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 ''Manga/{{Psyren}}'', [[spoiler: the membrane that surrounds the planet is actually a being which reincarnates by eating planets.]]
* The ''Anime/MagicalGirlLyricalNanohaAs The Movie Second'''s version of the Darkness of the Book of Darkness, [[spoiler:[[ReptilesAreAbhorrent NachtWal]]]], which doesn't just destroy the planet its on but consumes it, piece by piece, growing larger the more it consumes, eventually swallowing the planet whole.
* [[spoiler: The Original Life Fiber]] from ''Anime/KillLaKill''. Much like Lavos below, it technically doesn't eat the planet itself, merely draining energy from the living things instead; also like Lavos below, once it's consumed its fill of the planet's energy, it spreads its children to other planets, destroying its host world in the process.
[[/folder]]

[[folder:Comic Books]]
* One of the two {{Trope Maker}}s is {{Galactus}}, from the MarvelUniverse. His appearance has varied significantly. In main universe, he's a [[WordOfGod non-abstract]] [[CosmicEntity universal function]] that resembles a giant of the same species as any viewer but a hundred times bigger, in UltimateMarvel he's a swarm of robots that both needs to eat planets and hates organic life, and in the second ''Film/FantasticFour'' movie he's a formless mass [[spoiler:although if you look ''really'' closely, you can make out Galactus's helmet within the swirling clouds at its core]].
-->"Of all the creatures in the vastness of the Universe, there is none like me. I was present at the birth of the Universe, and I shall be there at its end. Though I ravage worlds to live, I bear no malice toward any living thing. I simply do what I must to survive. And why must Galactus survive? For, no matter how many worlds I devour... How many civilizations I destroy... It is my destiny to one day give back to the Universe Infinitely more than I have ever taken from it. So speaks Galactus!"
** Then Marvel introduced Galacta, Galactus' estranged daughter. She has the same cravings her dad has, and is ''capable'' of devouring planets, but she keeps this urge in check by working as a superhero, feeding on malevolent forces of energy (which would be destructive if left unchecked). In between those feedings, she spends a lot of time trying to control her insatiable hunger by eating bacteria, mostly because anything more filling and she might go on a feeding frenzy that would destroy the world. [[spoiler:However, she's pregnant, and her baby has the same cravings even now, while still in her womb.]]
** Spoofed as Balactus in ''Minoriteam''.
** Revealed as the secret of the Celestials in the {{Elseworld}} ''EarthX''; they reproduce this way, by [[PlanetaryParasite parasitizing planets with their young]]. Galactus is their enemy.
*** Every time the Celestials succeed in this, it destroys the universe. Which doesn't bother the Celestials, since they can survive it, and this is the only way that they can make more of themselves. Galactus was revealed to have originally been a survivor of a previous universe that the Celestials destroyed, and dedicated his life to stopping them from ever succeeding again.
** The main universe Galactus, despite being pretty omnicidal, is vital to the survival of the universe. He's a [[SealedInsideAPersonShapedCan living seal]] keeping an EldritchAbomination locked up, and without him, it'd destroy the universe very, very quickly. Most of the energy from his meals go towards the seal rather than his own body, which is why he's always so ''hungry''.
** There's also Hunger, who was sort of like Galactus, except it fed on ''universes''.
** DC has a largely-forgotten parody called Mr. Nebula, who doesn't eat planets, just re-decorates them by wiping out all life. He is placated by being given Las Vegas, which is about what he's going for.
* Marvel also has Ego the Living Planet, who is himself [[spoiler:eaten by cosmically powered zombified superheroes]] in ''MarvelZombies''.
* In the Marvel cosmic miniseries "Annihilation", the extradimensional invaders fielded a gigantic, organic, ''living'' spaceborne weapon called the "Harvester of Sorrows" which destroyed entire worlds and consumed the remains. What was left of the organic life was separated out so the crew could enjoy it.
* 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.
* The Sun-Eater from ''ComicBook/{{Legion Of Super-Heroes}}'', 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''.
* The World Devastators from the ''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 Original Insect from ''[[MichaelMoorcock Michael Moorcock's Multiverse]]''.
* Dark Phoenix in ''ComicBook/{{X-Men}}'' proved even more dangerous than Galactus considering she got sustenance from stars, causing them to go nova, which destroyed one populated planet. The Shi'ar and their allies realize that while Galactus is bad enough, having a menace that destroys ''whole solar systems'' is something they have to move against at any cost. And eating stars is only the beginning; Dark Phoenix had the potential to destroy ''the entire universe'', and in some alternate continuities it ''did''.
** 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.

[[folder:Film]]
* In ''TheReturnOfHanuman'', [[spoiler:a monster formed from a volcano named "Armageddon" is supposed to eat the contents of Earth entirely if Hanuman didn't stop him]].
[[/folder]]

[[folder:Literature]]
* The new Borg Cube from PeterDavid's ''Franchise/StarTrek'' ExpandedUniverse novel ''Before Dishonor''. [[spoiler:It [[PlutoIsExpendable eats Pluto]]. (Just before it becomes moot, it was revealed that it had been re-planetized by the time of its destruction.)]]
** And the Black Mass from the ''StarTrekNewFrontier'' books, which eats planets and then has their suns for dessert.
* This was the focus of one ''TheStainlessSteelRat'' novel.
* It's not alive, but the gigantic Green Sun from ''Literature/TheHouseOnTheBorderland'' ''consumes'' every planet in the solar system, and the sun as well.
* The Roar from ''The Silver Sequence'' is a member of a species that eats planets, or at least all the life on them.
* The Forerunners in ''TheHistoryOfTheGalaxy'' series feed on ''all'' forms of matter from space dust to planets. They are not particularly large but are able to breed (through mitosis) at tremendous rate after eating. The Forerunner Crisis occurred 3 million ears ago, when a swarm of these low-intelligence creatures was moving through systems attracted by starlight and leaving only stars with no planets in their wake. They were finally stopped by a species-wide HeroicSacrifice of a [[{{Precursors}} Precursor]] race. One of the novels reveals that the Forerunners are, in fact, [[spoiler:creations of an EnergyBeing, designed as its vessels. They were created with prototype [=DNA=] molecules. Some of them died on various planets, resulting in {{Panspermia}}. They weren't designed to go crazy, though]].
* In ''{{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.]]
* The main character in the short story ''Thang'' eats planets.
* In Creator/KeithLaumer's ''Literature/{{Retief}}'' story, "The Garbage Invasion", the [[ExtremeOmnivore Basurans]] want to take over the paradise planet of Delicia so they can eat it, the way they did their home planet.
* The organisms in the book ''Moonseed'' by Stephen Baxter. "It eats planets. And it's here".
[[/folder]]

[[folder:Live Action TV]]
* The Cetus from ''Series/{{Andromeda}}''
* The titular "Doomsday Machine" in the ''Series/StarTrekTheOriginalSeries'' episode broke up planets and devoured 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 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]].]]
** 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 titular CoolShip from ''{{Lexx}}'' loves (and needs) to do this. The Lexx even took [[spoiler: a few bites out of Earth.]]
** In season two, Mantrid went one better by eating [[spoiler: the entire ''universe''. Technically, dismantling it and converting it into his drones, but they are arguably a part of his body.]]
** In a twist, the Lexx actually receives ''less'' nourishment from doing exactly this, as it needs protein from organic material for sustenance; this is why the Lexx only eats [[spoiler: Holland]] instead of [[spoiler: the moon]], it's just that 'accidents' happen and the rocky ("not very tasty") remains of an exploded planet are all it has to make do with.
* ''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.
* From ''Series/DengekiSentaiChangeman'' [[spoiler: [[BigBad Star King Bazoo]] turned out to be this]]
* One ''Series/SesameStreet'' skit had Cookie Monster eat the Moon.
[[/folder]]

[[folder:Pinball]]
* The Doomsday Machine from Creator/DataEast's ''[[Pinball/StarTrekDataEast Star Trek]]'' pinball.
[[/folder]]

[[folder:Poetry]]
* Creator/ShelSilverstein's "Hungry Mungry" is about a boy whose ravenous appetite works up to and beyond this level.
--> And when he'd eaten every state, each puppy, boy and girl
--> He wiped his mouth upon his sleeve and went to eat the world.
[[/folder]]

[[folder:Tabletop Games]]
* The [[HordeOfAlienLocusts Tyranids]] of ''TabletopGame/{{Warhammer 40000}}'' 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.
* The Eldrazi in ''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.
* In the ''TabletopGame/YuGiOh'' game, there's a high-Level Synchro Monster called [[http://yugioh.wikia.com/wiki/Star_Eater Star Eater]]; if its name is any indication, it takes this Trope up one notch further. (Given how powerful it is, it's possible; it could override the effect of Number 9: Dyson Sphere.)
[[/folder]]

[[folder:Video Games]]
* ''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.
* One of the entries in the ''{{Gradius}}'' series, ''Life Force/Salamander'', has one of these as the storyline: you have allowed yourself to be swallowed by Zelos, a creature so large it eats ''entire solar systems'', so that you can fly through his body and take down his organs one by one with your heavily armed spaceship.
* The Qualia, from ChaosRings.
** The Qualia takes it UpToEleven with the fact that it seeks to destroy [[OmnicidalManiac spacetime itself]].
* In ''StarControl 2'', one of the Umgah's pranks is to convince the Spathi of the existence of a "Grand Master Planet Eater".
* Byron, and by extension Polidori, from ''[[VideoGame/{{Boktai}} Lunar Knights]]''.
* Parasitis, from ''VideoGame/{{Abadox}}'', digested the titular planet and assumed its shape. Parasitis obviously takes the maxim "you are what you eat" too seriously.
* Pyron from the Capcom game ''VideoGame/{{Darkstalkers}}'' is similar to this in most regards, although he usually prefers wiping all life off the face of the planet and letting a new race come into power before starting it over again.
* In ''VideoGame/ChronoTrigger'' and ''VideoGame/ChronoCross'', Lavos is gradually eating the planet's energy from the inside, having first attached itself in 65,000,000 B.C. What makes it particularly nasty is that Lavos is heavily implied to alter evolution on the planets it lands on, so that local sentients become more intelligent and advanced. Why? ''[[ForTheEvulz That makes the meal more filling]].''
** ''Cross'' expounds on this to make matters more complex: Lavos enhances the DNA of the planet's native life, creating sentience, then incorporates that DNA into its offspring, killing the planet so that its evolved young can move on to other worlds, continuing the life-cycle. This is a very literal take on the [[http://en.wikipedia.org/wiki/Panspermia Panspermia]] theory of life propagation, with Lavos as the sperm that penetrates and fertilizes the egg, Earth. This kind of sucks for the Earthlings in the long run, but after all you can't hatch an egg without breaking it.
* 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]].
* In ''VideoGame/{{Wild ARMs 2}}'', [[spoiler:the Encroaching Parallel Universe, Kuiper Belt, is gradually devouring not only the planet Filgaia, but Filgaia's entire universe, in what is termed the "Stain Paradigm".]]
* In ''VideoGame/{{Xenogears}}'', [[spoiler:the removal of the Limiters from the planet's population causes most of them to suddenly transform en masse into Wels, and it is revealed that all humanity on the planet was allowed to grow and thrive so that they could be consumed as raw materials for Deus.]]
* In ''VideoGame/{{Xenosaga}} Episode II'', [[spoiler:the activation of Proto Ω on Miltia causes it to instantly devour the planet from the inside out for raw materials, and then literally hatches out of the planet like an egg, throwing off pieces of its crust like egg shells]].
* The Old Gods from ''VideoGame/{{Warcraft}}'' are planetary parasites that merge themselves to a planet and slowly corrupt it. Whether this would eventually destroy the planet is unknown, as the Old Gods on Azeroth were sealed away by the Titans (they could not be killed, having already corrupted the planet to such a degree that removing them would've required the destruction of Azeroth).
* The Star Forge in ''KnightsOfTheOldRepublic'' is a variant of this - it feeds off a star to create vast swathes of technology for the Sith army. Whether it would eventually destroy the star it's using for energy and raw material is unknown (the star it's found orbiting seemed undamaged, and the math at least suggests that it's unlikely)
* Darth Nihilus in ''[[KnightsOfTheOldRepublic Knights of the Old Republic II]]'' is (or was) a ''person'' who consumes the life-force of planets through the Force, leaving them barren rocks in space. [[spoiler: It turns out this is pretty much all he does, since his hunger is all-consuming and all that motivates him.]]
* Some Space Monsters from the first and second ''VideoGame/MasterOfOrion'' games will eat planets if you don't stop them, leaving behind only "a barren, radioactive husk".
* The title of the final chapter of ''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.
* USG Ishimura in ''VideoGame/DeadSpace'' is a humongous scraper capable of gutting a whole planet and collecting its mineral resources. So basically it's a human-made planet eater/coal miner. Repeat that to yourself and realize the awesome.
** ''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.]]
* Guhnash from ''FossilFighters'', a gigantic space-fish-Pac-Man creature, presumably of the physical-devouring variety of planet eaters. [[spoiler: Around 600 million years ago, it ate the dinaurians home planet. Thanks to their subsequent attempts to 'correct' the evolutionary path of Earth, it starts making its way there.]]
* The Grey Goo of ''TastyPlanet'' eventually becomes one.
* The [[{{Albion}} Toronto]] 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 planet Fusion is this in Cartoon Network's {{Fusionfall}}.
* Phaaze from MetroidPrime is, itself, [[ThatsNoMoon a living planet]] however, it sends out its offspring to corrupt and devour other planets as a method of reproducing.
* The entire game ''[[{{Gradius}} Life Force]]'' takes place inside one of these. Half the levels are organic themed, while the other half are apparently the surface of the actual planets that were consumed.
[[/folder]]

[[folder:Web Comics]]
* Parodied in ''Webcomic/CaseyAndAndy'' with the Planet Devourer, which ''can'' eat planets... eventually. (It's about the size of a canary, with a similar rate of digestion.) It does eat Mars at one point... except it's OnlyAModel.
* One in the Star Trek parody arc of QuentynQuinnSpaceRanger.
* ''WebComic/EightBitTheater'' gives us the '''[[http://www.nuklearpower.com/2010/03/02/episode-1222-one-of-the-better-singularities/ Cakelogical Singularity!]]''' [[spoiler:Too bad it didn't actually work out, but even just the idea is awesome.]]
* ''{{Wonderella}}'' has Ginormous, who travels the universe eating things that deserve to be eaten. She occasionally talks him out of eating the Earth.
[[/folder]]

[[folder:Web Original]]
* The Devourer of Worlds from ''AHDotComTheSeries''.
* The [[spoiler:power granting Entities]] of ''Literature/{{Worm}}'' don't literally eat planets, but they do regularly obliterate them to make use of their mass energy as part of their life cycle.
* In [[https://sites.google.com/site/terrenwiki/home Terren]] the goddesses Pura Velpormia and Hellmasin Miastrius swallow heavens and hells, respectively, whole. Unless they decide to wear them as jewelry instead. The [[http://yumi-akiyama.tumblr.com/ creator]] also draws some [[AttackOfTheFiftyFootWhatever macros]] that grow big enough to eat planets in a more conventional sense, but one of them was still [[https://www.dropbox.com/s/xl4in9zndnrtl04/vore%20chain5.png nothing more than a snack]] for Velpormia.
* There is a [[Wiki/SCPFoundation 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.'']]

[[folder:Western Animation]]
* [[OrsonWelles Unicron]] from ''{{Transformers}}'' is the other TropeMaker, starting with ''TransformersTheMovie'' (1986), where his first appearance doubles as his [[DoomedHometown first meal]] and the animated film's opening scene. ApocalypseWow! Depending on continuity, he's also more evil than Galactus: as a [[GodOfEvil dark god]] in a [[OurGodsAreDifferent crunchy robot shell]], Unicron doesn't actually ''need'' to eat anything. He just considers the mere existence of [[strike:life in]] the universe to be a personal affront against him. Incidentally, he is [[SuspiciouslySpecificDenial most definitely not]] to be [[CaptainErsatz confused with Galactus]] (although Marvel may have had a hand in ''The Transformers: The Movie'', and was publishing the ''Transformers'' comic at the time).
* ''[[WesternAnimation/DextersLaboratory Dial M for Monkey]]'' brought us the Galactus parody Barbequor, who tried to turn the entire solar system into a shishkabob.
* Coop battles one of these in ''MegasXLR'', after it has the gall to disrupt his wrestling show. He destroys it by feeding it a missile packed with soda and Pop Rocks. And that's by accident. His first attempt -- a MacrossMissileMassacre -- is incredibly effective at devastating an area the size of New York City, on a creature the size of Earth. So then he tries smashing it...
* The Beast Planet from ''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.
* Spoofed as Omnipotus in ''TheTick''.
-->'''Omnipotus:''' Okay, I won't eat Earth now, but may I [[DefaceOfTheMoon take a bite out of the moon]] as I go?
-->'''Tick:''' Sure. Go ahead.
* In the 90s ''[[SpiderManTheAnimatedSeries Spider-Man]]'' animated series, ''Dr. Strange'' villain Dormammu could devour ''entire dimensions.''
* Hungorto, in ''DuckDodgers'' is Galactus, right down to having a cosmic-powered Herald. He is defeated when the combined forces of Earth and Mars throw all their food at him.
* Seemingly played straight but ultimately averted with The Darkness in TheFairlyOddParents three part special, it eats planets, but it's just defending itself because the denizens of the planets he's passing by freak out and attack it for looking menacing, when it's all sorted out, it spits out everything/everyone it and its termi-errr, eliminators ate.
** And who could forget [[LargeHam "GALACTIMUS! EATER OF ALL PLANETS!"]]
* [[http://www.youtube.com/watch?v=JFstPS3-CzY&list=PL76DAF0EBB15A9A5F A]] GarfieldAndFriends MusicalEpisode ended with {{Garfield}} becoming this - in a possible reference to [[http://www.garfield.com/comics/vault.html?yr=1987&addr=870517 this strip]].
* This theme was revisited in ''StarTrekTheAnimatedSeries'' with 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.]]
* The reboot of ''[[WesternAnimation/MaxSteel2013 Max Steel]]'' has this in the BiggerBad Makino who combines it with TheAssimilator as the reason for his actions. One of the [[BattleCry battle cries]] of his troops sums it up:
--> ''Absorb and expand!''
[[/folder]]

[[folder:Real Life]]
* Black holes, if they get close enough.
* Near the end of some stars' life cycles, they will expand and envelop nearby bodies, including planets. This is the likely end of Mercury and Venus, considering the type of star we orbit. Earth is an open question; some astronomers suggest that the sun won't quite reach earth's orbit of the time (somewhat farther out than now).
