* In the last level of ''VideoGame/TastyPlanet'', the Grey Goo eats "Time Itself". When even this is eaten and there's absolutely nothing left, [[spoiler:the Grey Goo implodes and become the next Big Bang]].

* ''Franchise/{{Transformers}}'': While Unicron ''appears'' to be a "mere" PlanetEater, he actually feeds off of existence itself in his bid to [[OmnicidalManiac eliminate all of reality]] and be truly alone. In every continuity, he's the same individual, at some different point in his existence. Some universes he devours, others are saved from him, and he's shunted to the next one to begin the cycle anew. According to the Transtech Cybertronians, Unicron has successfully terminated 1,176,325 universes so far (out of 15,962,782 catalogued by them). He actually managed to devour all of creation at one point, but it was re-created while he slept.

* ''Literature/ShakuganNoShana'': The Denizens of the Crimson World are monsters from another world who consume the "power of existence" of humans. If they eat your power of existence, you're RetGone'd from reality. Interestingly, the majority of the cast are such [[HumanoidAbomination monsters]], and a significant number of them try to find a way to get around their morally-indefensible diet. [[spoiler:They eventually find a way, thanks to Snake-Yuuji.]]

** [[Recap/BigFinishDoctorWhoDOTD11TheTimeMachine "The Time Machine"]] has the Creevix, InsectoidAliens who are the [[TimeMaster masters of time]] from the next universe along. They consume potential future and in an AlternateTimeline consumed the Universe after entering on 23 November 2013. With a massive TimeyWimeyBall the Eleventh Doctor influences his previous selves to stop their plan.

* ''ComicBook/CrisisOnInfiniteEarths'': The Anti-Monitor of ''Franchise/TheDCU'' destroys and absorbs the energies of many universes to become stronger.
* ''ComicBook/FinalCrisis'' introduces Mandrakk the Dark Monitor, a normal [[TheWatcher Monitor]] corrupted into a vampiric being that feeds on the Bleed, the dimension between realities that separates and defines them.
* ''ComicBook/{{Shazam}}'': [[spoiler:Mister Mind]] almost became this in ''ComicBook/FiftyTwo'', bringing the 52 alternate universes in existence (their main differences being the parts of the respective realities which he "ate").
* ''ComicBook/AllStarSuperman'' had the Chronovore, a monster that eats time. When it feeds, the surrounding environment and creatures suffer RapidAging.
* ''Franchise/{{Transformers}}'': While Unicron ''appears'' to be a "mere" PlanetEater, he actually feeds off of existence itself in his bid to [[OmnicidalManiac eliminate all of reality]] and be truly alone. The dark god has already devoured more than a fifth of the multiverse. He actually managed to devour all of creation at one point, but it was re-created while he slept.

* ''ComicBook/TheMightyThor'': The Black Winter is a cosmic entity that does to entire universes what [[Characters/MarvelComicsGalactus Galactus]] [[PlanetEater does to planets]].

* In ''Fanfic/PonyPOVSeries'', Makarov absorbs other beings, which causes them to be RetGone'd. The author describes him as an "Existence Vampire".
* In the ''Franchise/HarryPotter'' fanfic ''Fanfic/KingOfKingsRulingOverRulers'', Ayavan is capable of consuming the timeline of living beings.

* ''Film/TheNeverendingStory'': The Nothing is consuming the land of Fantasia. If it isn't stopped, Fantasia will be destroyed.

* [[Franchise/CthulhuMythos "The Space Eaters"]] by Creator/FrankBelknapLong begins with a conversation between the narrator and his friend on such {{Eldritch Abomination}}s:
-->"Suppose there were a greater horror? Suppose evil things from some other universe should decide to invade this one? Suppose we couldn't see them? Suppose we couldn't feel them? Suppose they were of a color unknown on Earth, or rather, of an appearance that was without color?... What could we do? Our hands would be tied. You cannot oppose what you cannot see or feel. You cannot oppose the thousand-dimensional. Suppose they should eat their way to us through space!"
* Creator/StephenKing's ''Literature/TheLangoliers'' has an airliner fly through a "time rip", landing at an airport with all its passengers but ten disappeared. The ten passengers, who were all sleeping during the passage through the rift, are all stuck in time such that time does not move forward (although they can move within that frame). Eventually, they see mysterious ball-like creatures with sharp gnashing teeth literally "eating" the surrounding existence itself, approaching them....
* In ''Literature/{{Discworld}}'', [[EldritchAbomination the Things from the Dungeon Dimensions]] want to invade the Disc because their home is sorely lacking in reality. They believe invading the Disc and consuming its reality will make them more real, though it's stated to be as futile as the ocean trying to warm itself with a candle.

* ''Series/DoctorWho'': In "[[Recap/DoctorWhoS9E5TheTimeMonster The Time Monster]]", the Master attempted to control a powerful being called Kronos, whom the Doctor referred to as a Chronovore, or time-eater.

* ''TabletopGame/MageTheAwakening'': The Abyss as a whole constantly gnaws at reality, for it is anti-reality made manifest, a realm of contradiction, paradox and negation opposed to existence as we know it.

* Unicron from ''Franchise/{{Transformers}}'' eats universes. In every continuity he's the same individual, at some different point in his existence. Some universes he devours, others are saved from him, and he's shunted to the next one to begin the cycle anew. According to the Transtech Cybertronians, Unicron has successfully terminated 1,176,325 universes so far (out of 15,962,782 catalogued by them).

* {{Superboss}} Culex in ''VideoGame/SuperMarioRPG'' claims to be this, in his BadassBoast.
-->''"I am matter... I am antimatter... I can see your past... I can see your future... I consume time... And I will consume you!"''
* ''VideoGame/GreyGoo2015'' has The Silence. Little is known about it, but it's capable of consuming literally everything it touches and leaving behind nothing but darkness. That black mass of empty space in the sky at night where there's a gap in the stars? That's The Silence. It eats light, sound, and, well, pretty much everything.

* ''Franchise/SonicTheHedgehog'' has two:
** From ''VideoGame/SonicTheHedgehog2006'', there's the god of time and light Solaris, who plans to devour all of existence.
** ''VideoGame/SonicGenerations'' has the Time Eater, a creature that eats holes in space and time and throws Sonic into places he's been to before (including [[VideoGame/SonicTheHedgehog2006 one]] that he has visited before, [[CosmicRetcon but also technically didn't and probably shouldn't be able to return to]]). [[spoiler:It turns out that it's an EnergyBeing that Eggman and his past self turned into a cyborg-mech-abomination.]]
* ''VideoGame/{{Marathon}} Infinity'' has W'rkncacnter, who as soon as it escapes from its prison in the sun screws with reality just by existing, and THEN it starts eating.

* In the ''VideoGame/FreeSpace 2'' mod ''VideoGame/BluePlanet'', overheard thoughts of SufficientlyAdvancedAliens reference something they call an "ontovore". The word's etymology suggests that it refers to something which consumes existence. They also refer to the same thing as an "[[http://en.wikipedia.org/wiki/Acatalepsy acatalepsis]] event". Not a whole lot is known about it, and it's implied that even thinking about the subject is [[ThingsManWasNotMeantToKnow dangerous to one's mental health]].
* In the last level of ''VideoGame/TastyPlanet'', the Grey Goo eats "Time Itself". When even this is eaten and there's absolutely nothing left, [[spoiler:the Grey Goo implodes and become the next Big Bang]].
* ''VideoGame/LeagueOfLegends'' has the non-canon "Dark Star" skins for several champions that are built off this concept, turning them into {{Cosmic Entit|y}}ies who annihilate and feast off entire galaxies at a time. The line is codified by [[OmnicidalManiac Dark Star Thresh]], an AnthropomorphicPersonification of a black hole who believes time is a cog in a dying machine, and is already responsible for [[ApocalypseHow/ClassX4 the cessation of multiple]] ''[[ApocalypseHow/ClassX4 realities]]'' by the time he hits Runeterra.
* ''VideoGame/StarControl Origins'': The {{Greater Scope Villain}}s of the game are beings only referred to as the Gluttonous Eyes. They are extra-universal entities that somehow consume ''information'' and spread chaos in their wake. How exactly someone is supposed to fight or resist such entities is unclear:

* ''VideoGame/SonicTheHedgehog'' has two:

* ''LightNovel/ShakuganNoShana'': The Denizens of the Crimson World are monsters from another world who consume the "power of existence" of humans. If they eat your power of existence, you're RetGone'd from reality. Interestingly, the majority of the cast are such [[HumanoidAbomination monsters]], and a significant number of them try to find a way to get around their morally-indefensible diet. [[spoiler:They eventually find a way, thanks to Snake-Yuuji.]]

* BonusBoss Culex in ''VideoGame/SuperMarioRPG'' claims to be this, in his BadassBoast.

* In ''VideoGame/TastyPlanet'', in the last level you eat "Time Itself". When even this is eaten and there's absolutely nothing left, [[spoiler:you implode and become the next Big Bang]].
