History Main / PlanetEater

[[folder:Films -- Animation]]
* In ''Animation/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]].

* The main character in the short story ''Thang'' eats planets.

* The Devourer of Worlds from ''Script/AHDotComTheSeries''.

* The Star Forge in ''VideoGame/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 ''[[VideoGame/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.]]

* The Toronto of ''VideoGame/{{Albion}}'' is another example of man made Planet Eater. 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.

* One of the two {{Trope Maker}}s is ComicBook/{{Galactus}}, from the Franchise/MarvelUniverse[[note]][[Franchise/{{Transformers}} Unicron]] is the other[[/note]]. He is a "planetary energy"-type Planet Eater. His appearance has varied significantly. In the main universe, he's a [[WordOfGod non-abstract]] [[CosmicEntity universal function]] that [[YouCannotGraspTheTrueForm resembles a giant of the same species as any viewer]] but a hundred times bigger, while in ComicBook/UltimateMarvel he's a HiveMind swarm of robots that both needs to eat planets and hates organic life, and in the second ''Film/FantasticFour2005'' 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]]. He's a necessary part of the cosmic balance, which is why he can't be killed off permanently.

** Moro from the Galatic Patrol arc of the Anime/DragonBallSuper manga drains entire planets of their energy, which he then consumes.

Subtrope of PlanetDestroyer (because a being who eats planets for breakfast would also have the necessary strength to destroy it).

->''"Creator/StanLee thinks big. He came up with ComicBook/{{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."''

* ''Series/KamenRiderBuild'' has [[spoiler: Evolt, the BigBad. He travels from planet to planet, consuming them with black holes and using the energy gained to make himself even more powerful. He's personally responsible for [[OnceGreenMars Mars being a lifeless ruin]], but in the process lost most of his power and was forced to hide out on Earth while he tried to regain it. His EvilPlan during the later quarter of the series is to unlock warp travel so that he can do so even faster.]]

* In ''Myth/AztecMythology'' , the first earth, Jaguar Sun, was ended by Tezcatlipoca turning into [[PantheraAwesome the Jaguar God Tepeyollotl]] and devouring it.

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

* In ''Myth/NorseMythology'' , Fenrir's sons Hati and Skoll shall respectively eat the Moon and Sun when [[TheEndOfTheWorldAsWeKnowIt Ragnarok]] comes.

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.

* One early issue of ''ComicBook/{{Rat-Man}}'' features Cosmicus, a parody of Galactus right down to the heralds. [[KarmicDeath Gets devoured by Earth]], or, rather, the EldritchAbomination living under the surface. [[spoiler: Cosmicus is later revealed to be one of the villains created by Mr. Mouse for a superhero to fight and sell more comic books with their fight]].

* The Sun-Eater from ''ComicBook/{{Legion Of Super-Heroes}}'', which does ExactlyWhatItSaysOnTheTin.

* Creator/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 DoomsdayDevice and MechanicalAbomination built 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 ''ComicBook/{{Supergirl}}'' story arc ''ComicBook/{{Bizarrogirl}}'' a race of planet-eating, space-faring, giant life-forms called "Ash'ka'phageous" make their appearance. One of them -called "godship" by the denizens of Bizarro World because it's easier to pronounce- tries to devour SelfDemonstrating/{{Bizarro}}'s planet.

* Unicron from ''Franchise/{{Transformers}}'' is the other TropeMaker,[[note]]ComicBook/{{Galactus}} is the other[[/note]] starting with ''WesternAnimation/TheTransformersTheMovie'' (1986), where his first appearance doubles as his [[DoomedHometown first meal]] and the animated film's opening scene. He is a "eats the whole planet outright"-style Planet Eater. 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).

* ''Literature/MercyThompson'': The River Devil is a snake-like demon that plans to consume earth. The more it consumes, the bigger it gets, and it eventually plans on growing so large it can consume the world."

* In ''VideoGame/{{Stellaris}}'' [[HordeOfAlienLocusts Devouring Swarms]] composed of [[SiliconBasedLife Lithoids]] are known as Terravores and can slowly consume planets. Rendering them unusable after 10-20 years.

* Black holes, if they get close enough.
