* One of the two {{Trope Maker}}s is ComicBook/{{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 ComicBook/UltimateMarvel he's a 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]].

** An issue of ''ComicBook/TheSimpsons'' had Homer as a parody of Galactus who was hungry for planets. Marge as ''Nova'' expy wants him to eat a planet covered in healthy plants and Bart/ ''ComicBook/SilverSurfer'' recommends [[UranusIsShowing Uranus]]. Homer en da up ordering planets from a pizza-style delivery service.

* 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.

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

* In the '90s ''[[WesternAnimation/SpiderManTheAnimatedSeries Spider-Man]]'' animated series, ''DOctor Strange'' villain Dormammu could devour ''entire dimensions.''

* In a May 1987 strip of ''ComicStrip/{{Garfield}}'', Garfield has a dream while on a diet where he eats everything in sight and swallows the entire planet Earth before spotting other planets around him which he decides to also consume for dessert. In 2017, Jim Davis drew a Galactus comic for ''Squirrel Girl'' with Jon Arbuckle redesigned as the Silver Surfer.

--> 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.

* 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.

** The C'tan used to eat stars. This was a fairly slow process so for the most part no-one even noticed they were there. When eventually contacted by the Necrontyr and given physical bodies, they were no longer able to do so and are instead forced to consume the life energy of living beings. This is the reason the enslaved Necrons have been asleep for millions of years - the C'tan ate basically everyone in the galaxy, resorted to cannibalism, and the few survivors were eventually forced to hibernate since there was no food left. People just aren't as filling as stars. They are much tastier though.
* 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.

* There is an Wiki/{{SCP|Foundation}} 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.'']]

-->'''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 ''[[WesternAnimation/SpiderManTheAnimatedSeries Spider-Man]]'' animated series, ''Dr. Strange'' villain Dormammu could devour ''entire dimensions.''

* Seemingly played straight but ultimately averted with The Darkness in ''WesternAnimation/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.

* The [[ThatsNoMoon Big Gete Star]] in the ''Anime/DragonBallZ'' Movie "The Return of Cooler".

* The Chronophage in ''Manga/EdensZero'' is a combination of this and SpacetimeEater that specifically eats the ''time'' of planets, which "kills" them by rewinding them to an earlier state ranging from decades to millennia, creating a pocket AlternateTimeline that overwrites the present and [[RetGone erasing]] anyone unfortunate enough to stay behind.

* 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.

* In Creator/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 indie RPG ''Belly of the Beast'' takes place in the digestive tract of one after it scrapes off the surface of a MedievalEuropeanFantasySetting.

The ''Series/DoctorWho'' novel ''Sick Building'' features a Voracious Craw, a giant worm-like creature which devours everything it can on the planets it comes across, leaving behind only bare rock.

* Tuska from the MMORPG RuneScape came to the planet of RuneScape in an attempt to devour Gielinor after [[spoiler: Guthix's assassination and death]] but Gielinor was defended by four different rival factions (three controlled by: Armadyl, Saradomin, Zamorak; and one godless faction under Vorago's worship) and was then stopped by [[spoiler: Vorago]].

* ''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. His EvilPlan during the later quarter of the series is to unlock warp travel so that he can do so even faster.]]

* 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 to mostly to Clara, with some help from Ten and Eleven.]]
