[[caption-width-right:281:''This'' is what scares the Boogeyman.]]

->''"At the end there, when I was trying to cut a deal, the ambassador was ''scared''... That's why he wouldn't come to our aid. That's why we're on our own. Because the demons are afraid of what we're hunting."''
-->-- '''Mayor Bentham Rudgutter''', ''Literature/PerdidoStreetStation''

Humans are the dominant species. We're at the top of the food chain. [[CriticalResearchFailure That means that literally]] ''[[CriticalResearchFailure nothing]]'' [[CriticalResearchFailure in the world can successfully prey on humans]] (except maybe [[HuntingTheMostDangerousGame other]] [[ImAHumanitarian humans]]). That's part of what makes a lot of monsters scary and badass; they dethrone us from our position of power.

But when you think about it, eating people is kind of old-hat. After a while, you begin to lose track of [[EverythingTryingToKillYou all the different types of monsters that eat humans]]. It just becomes a fact of life, so by the time you run into that guy who wants to [[CannibalismSuperpower devour your flesh to add to his own power]], you just sort of yawn because it's exactly the same as everything you've seen anywhere ever. So how do you make something distinctive, then? Well, if monsters that eat humans are no longer a threat... what about monsters that eat other monsters? To establish a Food Chain Of Evil, all you have to do is [[TheWorfEffect make the last threat the preferred prey of the next one.]]

This will often result in situations of HorrifyingTheHorror for the first monster, where it's deathly frightened of the thing now trying to eat ''him''.

Anything which eats monsters that eat humans counts. Basically, this is power tiers established via fictional food chain.

Contrast ElementalRockPaperScissors and TacticalRockPaperScissors, where the food chain is circular. When this sort of food chain exists ''within'' a species, that's MonstrousCannibalism.

* AlwaysABiggerFish: The heroes are saved when the monster gets eaten by a bigger monster.
* MonsterLord: Also related, but a Monster leader that eats its own kind is distinct from this trope in that it's only one monster, not an entire species that preys on the other one (although it can still count if the Monster Lord is an entire multi-member monster caste unto itself).
* MonstrousCannibalism: When monsters of the same species eat each-other, rather than a ''separate species'' devoted to eating them, although there's a lot of overlap.

Not to be confused with [[PredatorsAreMean carnivores are evil]] or VillainPedigree, although there's probably some overlap with the latter.


[[folder:Anime and Manga]]
* The Crusniks from ''LightNovel/TrinityBlood'', who eat vampires. Though three of the four Crusniks to ever exist have been friendly to humanity (to an extent), including the hero Abel Nightroad.
* The Pillar Men in Part 2 of ''Manga/JoJosBizarreAdventure'' eat the vampires who were the primary antagonists in Part 1.
* Alucard fom ''Manga/{{Hellsing}}''. While technically a vampire in name, he's more of an EldritchAbomination in vampire's clothing, and his favorite food seems to be the vampires created by the BigBad.
* The Menos Grande from ''Manga/{{Bleach}}'' are created when the hunger of a group of [[TheHeartless Hollows]] becomes so great that they start feeding on each other, resulting in them merging into a near-mindless skyscraper-sized beast. If one of the constituent personalities can gain control of the others, then continuing to consume other Hollows eventually pushes them across the BishonenLine to become the human-like and insanely powerful Vasto Lordes.
* ''Anime/NeonGenesisEvangelion'' where Unit 01 goes berserk and [[spoiler:eats Zeruel]].
** Similarly in ''Anime/RebuildOfEvangelion'', Zeruel does this to [[spoiler:Unit 00]].
* ''Manga/{{Devilman}}'' features this often, mostly in the first OVA, as the demons will eat each other out of cannibalism.
* ''Manga/FullmetalAlchemist'' has this when Pride [[spoiler:eats Gluttony's philosopher's stone]].
* ''Anime/{{Godannar}}'' with the fusion type mimetic beasts trying to "eat" their brethren, although somewhat subverted as it actually makes them more powerful.
* ''Manga/GetterRobo'' with New Getter Robo when the giant onis eat smaller members of their kind to gain their intelligence.
* Cell from ''Anime/DragonBallZ'' needed to hunt down and absorb Dr Gero's other creations to reach his final form.
* Invoked in ''Anime/PuellaMagiMadokaMagica.'' The series's MonstersOfTheWeek, witches, devour humans and use them to reproduce. The core of a dead witch, a Grief Seed, is the only way for a [[MagicalGirl Puella Magi]] to replenish their strength, and so they hunt (or, in some cases, even cultivate) witches. One [[BloodKnight particularly cold]] girl, Kyouko, even calls it a food chain, with them at the top. [[spoiler:As it turns out, [[AllYouNeedToKnowAboutTheCryingGame Puella Magi are merely the larval forms of witches,]] and the discarded Grief Seeds are ultimately fuel for [[StarfishAliens their creators.]]]] Some fans have even produced [[http://wiki.puella-magi.net/Population_dynamics population dynamic models.]]
* In ''Manga/ViolinistOfHameln'', Mazoku feed on humans. They can also raise their power by drinking magical blood, which can be from human mages... or other Mazoku. [[BigBad Demon King Chestra]] is known to eat lesser Mazoku [[spoiler: and even planned to eat his own children]].
* ''Manga/TokyoGhoul'' has one in the form of the rare [[InstantArmor Kakuja]] mutation, the result of Ghouls that engage in MonstrousCannibalism one time too many. Incomplete Kakuja such as [[spoiler: Kaneki Ken]] are near-mindless monsters, while the fully-evolved ones such as the [[TheDreaded One-Eyed Owl]] and [[BigGood Yoshimura]] are the strongest and most terrifying Ghouls on record. The legends about the Kakuja are one reason that cannibalism occurs among Ghouls, with those actively seeking to increase their power risking the resulting mental breakdown that goes along with it. Ghouls might eat humans (and occasionally weaker Ghouls), but the Kakuja eat whatever the hell they want and are almost without exception super-predators of incredible power.

* Tryks hunt down and infect the various species of vampire in the MarvelUniverse. They need normal humans to reproduce though. Deacon Frost also tries to become a creature above vampires on the food chain himself but instead gets eaten by one.
* One of the non-canon ''Series/{{Angel}}'' comic books had him deal with the returning threat of a giant tentacle monster that fed on vampires by sucking out the demon inside of them. Angel [[PayEvilUntoEvil wouldn't have a problem with this,]] except that when the creature reaches its maximum of 3000 demons, they'll all be expelled from its body...in a spirit form that will let them directly possess living humans, instantly turning 3000 people into vampires in one night.
* In an interview, ''ComicBook/HackSlash'' creator Tim Seeley once mentioned a scrapped storyline that would have involved a slasher who preyed solely on vampires.
* A few ''ComicBook/{{Venom}}'' stories featured Xenophages, monsters that feed on symbiotes.
* From ''ComicBook/WitchDoctor'', [[spoiler: Penny Dreadful]] is a cryptophage: a monster whose diet consists ''entirely'' of other monsters.
* In ''ComicBook/{{Vampirella}} vs. Franchise/{{Alien}}s'', the Xenomorphs basically fill this role for the vampires. The comic opens with a bunch of Nosferatu being hunted by them, the last of whom tries to fight back by sinking his fangs into an alien. [[BloodyMurder Bad idea]].
* Galactus was first introduced by showing the Skrulls, some of the most threatening villains the Fantastic Four had faced up until then, terrified of him and doing their best to conceal their home planet so he wouldn't find and eat it.
** In a later story, Galactus successfully devoured the Skrull homeworld and its inhabitants.
** Galactus himself was once considered a prospective meal, along with the rest of the universe, for an interdimensional being known as Hunger.

* The Reapers in ''Film/BladeII'', as shown atop this page, feed on vampires. Though they were not above snacking on humans too. The only way to kill them was the sun, as they had a solid bone plate over their heart, and easily healed from a broken neck. They could probably survive decapitation as well; a victim in the middle of turning survived a partial decapitation. After the body was destroyed, the remaining piece was still looking around and blinking with its eye.
* Subverted in ''Film/{{Godzilla 2000}}''. In the climax of the movie, Orga attempts to swallow Godzilla whole. Godzilla uses his atomic breath on its insides and kills it.
* In ''Film/{{Rodan}}'', the titular giant pterosaur is first introduced as a predator that eats the BigCreepyCrawlies called Meganulon that had previously been the threat in the movie.
* Marcus from ''Film/UnderworldEvolution'' becomes a vampire/lycan hybrid. From this point, he becomes pretty much omnivorous.
* ''Film/TheValleyOfGwangi'': The titular allosaurus eats a styracosaurus and a gallimimus.
* ''Film/PlanetOfTheDinosaurs'': The tyrannosaurus rex eats a rhedosaurus while chasing the human characters at one point.
* ''Film/{{Evolution}}'': Mostly at the stage of alien evolution where the meteor crash site resembles the Carboniferous Era.
* ''Film/StarWarsEpisodeIThePhantomMenace'': In the subterranean oceans of Naboo, giant sea monsters such as the eel-like Colo Claw Fish and the fish-crustacean hybrid Opee Sea Killer are hunted by an even larger leviathan, the Sando Aqua Monster.
* ''Film/TheCosmicMonsters'': A giant spider (that somehow changes between a tarantula and a funnel web) catches a cockroach in its web and fights it, eventually winning and wrapping it up.
* ''Film/GhouliesII'': The Ghoulie Eater, who does what exactly what his name says and eats all but the Fish Ghoulie.
* ''Film/KingKong2005'': The vastatosaurus rex eats a foetodon. This is also heavily used in the game based on the film.
* ''Franchise/JurassicPark'':
** The ''T. rex'' in [[Film/JurassicPark the first film]] eats a ''Gallimimus'' and a ''Velociraptor''.
** ''Film/JurassicParkIII'' also has this with the notorious scene of the ''Spinosaurus'' killing the juvenile ''Tyrannosaurus''.
* ''Film/MegaPiranha'': The titular monsters feed on each other if one is hurt. The feeding frenzy is so crazy that it [[spoiler: ends up causing them to kill each other at the end]].
* ''Film/MegaSharkVsCrocosaurus'': Mega Shark proceeds to eat Crocosaurus's eggs throughout the movie.
* The main character in ''Film/HuntingHumans'' has a NightmareSequence where the fellow SerialKiller who has been hassling him appears as a supernatural creature that preys on infamous murderers.
--> "I'm the reason UsefulNotes/JackTheRipper was never caught, and I'm the reason you'll never be caught. You're hunting humans, and I'm hunting ''you''!"
* In ''Film/{{Daybreakers}}'', vampires can mutate by drinking their own blood, turning into Subsiders, feral and incredibly dangerous bat/human hybrid monsters. They feed mostly off the blood-drinking but much more human vampires, but will eagerly take human blood too whenever they can get it.
* In ''Film/QueenOfTheDamned'', Akasha drinks the blood of vampires and humans alike.
* Quite literal in ''WesternAnimation/HowToTrainYourDragon'' with the Green Death. Some of the dragons are huge in comparison to the human characters (Zipplebacks and Monstrous Nightmares especially, but even Night Furies are big dragons) but ridiculously tiny compared to the Green Death, which is possibly their HiveQueen. In fact, the regular dragons aren't even evil at all; they simply have to return to the dragons' nest with food or they'll be eaten.

* Giant spiders in ''Literature/HarryPotterAndTheChamberOfSecrets'' fear the basilisk. But even the mighty basilisk is afraid of roosters. And roosters fear humans, which fear giant spiders, which fear basilisks, which fear roosters...
* In "Literature/TheShadowOutOfTime" by Creator/HPLovecraft, the Great Race of Yith, for all their power and clear superiority, seem terrified of the [[Franchise/CthulhuMythos half-material entities]] [[SealedEvilInACan sealed beneath the earth.]]
* In Creator/RogerZelazny's short story ''Dayblood'', the titular Dayblood feed on vampires. The only Dayblood present looks (and thinks) like human and doesn't seem to be particularly evil - more like ruthlessly practical. Interesting that vampires know at least some weaknesses of the Dayblood and use appropriate protections against them.
** Zelazny also wrote ''Itself Surprised'', a short story in Creator/FredSaberhagen's ''Literature/{{Berserker}}'' series about discovering an inactive anti-Berserker Berserker, unleashed long ago by the Red Race shortly before the Builders' [[VonNeumannMachine Berserkers]] wiped them out.
* The main issue in ''Literature/PerdidoStreetStation'' by Creator/ChinaMieville's are slake moths, giant dream and mind eating moths that scare the living crap out of ''devils''. In fact the slake moths are even shown to have eaten a vampire at one point in the book.
** And these slake moths are only halfway up the foodchain in their homeland. It's [[DeathWorld that kind of world]].
* Inverted in the original novel of ''Literature/IAmLegend''. The significance of the title is that, to the [[spoiler:living, sapient vampires rebuilding civilization]], Robert Neville is a terrifying monster who can hunt them during the day.
* The titular 3-foot-long man-eating crabs of J.F. Gonzalez' ''Clickers'' are only on shore in the first place because they're fleeing from 7-foot-tall FishPeople.
* In Creator/BarbaraHambly's ''Literature/ThoseWhoHuntTheNight'', someone, or some''thing'' appears to be hunting the vampires of London and draining all of their blood.
* The various monsters in Creator/StephenKing's novella ''Literature/TheMist'' have a clear food-chain, along with eating any humans they come across.

[[folder:Live Action TV]]
* ''Series/BigWolfOnCampus'' had a variation in an episode about vampires that can only eat werewolves.
* Species 8472 in ''Series/StarTrekVoyager'' are Borg biters. They see our entire galaxy as impure. They plan on killing everything else after they finish chowing down on the Borg.
* On ''Series/{{Supernatural}}'', there are creatures that gain power by consuming the blood of demons. [[spoiler:Sam is one of them.]]
* The Franchise/UltraSeries does this occasionally.
** ''Series/ReturnOfUltraman'': The whip-armed Gudon is Twin Tail's natural predator. This is even repeated in ''Series/UltramanMebius'' where the two's battle is interrupted by the ''Mebius'' example below.
** ''Series/UltramanTaro''
*** The very first episode where [[spoiler:Astromons eats Oil Drinker with the toothy flower on his torso]].
*** Also episode 17 and the beginning of episode 18 where [[spoiler:the avian Birdon hunts the insectoid Kemujira]].
** ''Series/UltramanEighty'': In episode 28, Zakira attempts this with an infant Baru (a peaceful monster), but fails.
** ''Series/UltramanGaia'': In episode 8, Crabgan absorbs Anemos for the two of them to become a more powerful hybrid monster.
** ''Series/UltramanMax'': Episode 30 in which the ice-breathing Lagoras eats the molten core of the fire-breathing Grangon to become Evolved Lagoras, which combines the powers of both into a far more dangerous beam. The two were shown fighting each other in the first episode too.
** ''Series/UltramanMebius'': Bogar and the lesser members of her species are basically mouths with a body. Their presence calls forth other kaiju from the depths of space or their tombs in the earth to be unwillingly consumed. Worse still, the Bogars use the energy gained from meals to evolve in power and appearance. Oh yeah, [[MonstrousCannibalism they also cannibalize their dead]] for the same effect.
* ''Series/StargateAtlantis''
** The Wraith are a terrifying race of lifeforce vampires who hunt, herd, and generally rule over humanity as a food source. However, [[spoiler:when Lt Ford was being fed upon, the process was interrupted and he discovered that the Wraith, in order to allow them feed longer, inject their victims with a powerful stimulant that makes the victim stronger. Cue Ford and some other Wraith survivors around the galaxy forming a group that hunts the wraith, harvesting their corpses for more sweet, sweet PsychoSerum]]
** There are also the Asurans: machines created by the Ancients to combat the Wraith. When the Asurans are activated, they become a much bigger threat than the Wraith when they decide to kill the Wraith by eliminating their food source... humans. Until they are dealt with, of course.
* In an early episode of ''Series/BuffyTheVampireSlayer'', a particularly fiercesome vampire is sent running at the sight of the She-Mantis, who wasn't even in her true form at the time.
* ''Series/TheVampireDiaries'' features [[TheDreaded Mikael]], an ancient vampire who hunts other vampires [[spoiler: because he doesn't drink the blood of the living, only other vampires.]]
* ''Series/RiverMonsters'' is a documentory about catching the scariest fresh water fish, not just the man-eaters, but the things that eat ''them''. Usually done on a catch and release basis, but sometimes people do end up eating them. Note: this is a documentory, so the fish that qualify are '''also''' Real Life examples.
* ''Series/{{Community}}'', "Horror Fiction In Seven Spooky Steps": "I am a werewolf who feeds on selfish vampires."

[[folder:Tabletop Games]]
* In ''TabletopGame/VampireTheMasquerade'', any vampire of a sufficiently low generation can develop the Elder's Thirst: they can only feed on other vampires. Their capacity for holding blood can be ten times that of a neonate, so when they're running on empty it takes a lot to fill them up. Luckily vampire blood is much more filling. Most vampires in the setting live in fear of [[TheEndOfTheWorldAsWeKnowIt Gehenna]], when the Antediluvians will rise from torpor to devour their offspring.
** Also, humans can be empowered somewhat by feeding them vampire blood -- but become enslaved to their donor. Sometimes they decide to go independent and find their own supplies. This is UsefulNotes/VladTheImpaler's backstory. [[note]]He was never a blood thrall, but before he was Embraced himself, he fed on captured Tzimisce, and shared the blood with loyal elite troops, thereby establishing himself higher on the food chain than the clan that had been terrorizing so many similar small European kingdoms.[[/note]] And then there are the Nagaraja, an obscure bloodline that requires a little bit of flesh with their blood.
** Some Elder vampires invoke this trope by specifically creating coteries of neonates (new vampires) to go out and fill themselves up with human blood, so their Sire can then fill up on vampire blood. Not enforced in the rules per se, but a very creepy and {{squick}}y piece of fluff.
* In ''TabletopGame/VampireTheRequiem'', similar examples to the above exist:
** Any vampire with Blood Potency 7 can only feed if they're willing to drink the blood of another vampire. There are drawbacks: addiction and the risk of being mind controlled by the victim. They can also get addicted to soul-eating other vampires through diablerie. Usually, any vamp getting this high a Blood Potency either ate his way up or existed for a very long time, both of which tend to make you extremely powerful. In the case of the former, they also tend to be quite psychotic due to diablerie eating away at your [[KarmaMeter Humanity]].
** Supplements have featured both the Macellarius, who gain the ability to truly digest food and a gourmand's desire for strange flesh, and the Noctuku who have a compulsion to eat the flesh of their victims as well as drink their blood, despite it providing no benefit to them -- it's more a dominance thing.
** As in ''Masquerade'', ghouls -- humans given vampiric abilities by addicting them to vitae (vampire blood) -- can sometimes go rogue and turn to hunting vampires to make them into food without having to slave for them. The ''Mythologies'' splat actually introduces the Phanariot, which are a ghoul strain that has managed to become immune to the [[MoreThanMindControl Blood Bond]] and so freely preys upon vampires.
** Naturally, vampires can suck blood from the various other supernatural splats. In first edition, this isn't always a good idea -- [[TabletopGame/WerewolfTheForsaken Urathra blood]] has a tendency to provoke Frenzy, for example. The ''Book of the Dead'' splat contains a merit that allows vampires to ''eat ghosts'' instead of drinking blood. In 2nd edition, the merit Unnatural Affinity exists specifically for the aforementioned too-strong vampires, allowing them to substitute the blood of non-vampire supernaturals for vampire blood.
* In the [[UpdatedReRelease 2nd edition]] of ''TabletopGame/WerewolfTheForsaken'', werewolves got tweaked so that Primal Urge had a similar drawback to Blood Potency above. Hitting Primal Urge 6 means that only the flesh of carnivorous creatures can sustain a werewolf, so if they don't want to starve to death, they need to start eating wolves and the like. Two points of Primal Urge later, and from then on, only the flesh of creatures that produce Essence will do. These big bad wolves can only nourish themselves on the flesh of humans (and by extension mages), spirits, and other werewolves.
** Also how spirits work. Each spirit must eat other spirits that are similar to it (a water spirit eating another water spirit, for instance) or compatible with it (a wolf spirit eating a rabbit spirit), basically making an almost cannibalistic food chain.
* Arguably the Necrons of ''TabletopGame/Warhammer40000'', the only race in existence with a working game plan to permanently destroy Chaos -- a sentient [[TheDarkSide dark side]] that operates by TheCorruption when it isn't taking matters into its own hands. Necrons are the entities that ''daemons'' are theoretically scared of, though Daemon players aren't usually scared of Necron players in practice.
* In ''TabletopGame/DungeonsAndDragons'', Bebiliths are demonic spiders whose favorite prey is other demons.
* ''TabletopGame/{{Pathfinder}}'': Umbral dragons and cairn linnorms are notable for hunting TheUndead as their favored food source. Of the two, umbral dragons prefer to feed on incorporeal undead such as ghosts and specters, while cairn linnorms, which cannot physically interact with ectoplasm, stick to the corporeal kind. That said, both will happily feed on humans if no better meal presents itself.

[[folder:Video Games]]
* The ''VideoGame/WhatDidIDoToDeserveThisMyLord'' series is all about creating a food chain ecology for your monsters. Slime molds roll around redistributing nutrients from the soil, the insectoid Omnoms eat the slimes to feed themselves and reproduce, Lizard Men eat Omnoms, and Lizard Men can be devoured by Dragons.
* In ''VideoGame/AmnesiaTheDarkDescent'', the player is stalked by a horrifying monster that can't be confronted or killed, and you spend much of your time running and hiding in terror. [[spoiler:About halfway through the game, you wander into a side room and find its dismembered corpse lying in a pile of TheCorruption, and realize you have bigger things to worry about.]]
* ''VideoGame/RatchetAndClank'':
** Amoeboids, and it is pretty much all they do.
** ''VideoGame/RatchetAndClankGoingCommando'': The arctic leviathans will eat Y.E.T.I. to restore their health if they are close enough.
* Seen often in ''VideoGame/DinoCrisis2'' where the tyrannosaur Scar is defeated by the giganotosaurus and eaten off-screen.
* In the first ''VideoGame/PaperMario'', Tubba Blubba eats Boos.
* If you get into a battle with both a Dung Beetle and a Sand Lizard in ''VideoGame/{{Mother 3}}'', the Lizard might eat the Dung Beetle for health. In the Sand Lizard's [[MonsterCompendium Battle Memory]] entry, the game [[LampshadeHanging mentions]] that the Dung Beetles clean up the Sand Lizard's dung, and, in turn, the Sand Lizards eat them.
* The lynchpin of the plot in ''VideoGame/MetroidFusion'': by killing all the Metroids in [=SR388=], Samus disrupted the natural balance of the ecosystem, resulting in the [[TheVirus X Parasites]] reproducing unchecked. This is, unsurprisingly, a Bad Thing.
* In ''VideoGame/NightmareCreatures'' you spend most of the game facing the tough and somewhat dangerous Pepys' Monsters (sort of large humanoid golems with extra limbs and heads). After a certain level you'll start meeting GiantSpider monsters, who has webbed and eaten one of said Pepys Monsters.
* In the second ''VideoGame/{{Splatterhouse}}'' game at the end of the first level you see three mooks progressively devoured by a larger creature beyond a door, quickly revealed to be the boss of the level.
* ''Franchise/{{Halo}}'':
** In the original trilogy, the Covenant are a collection of highly advanced alien species who look to be the main reason why humanity's about to go extinct... that is, until the Flood are released. After that, the Flood start assimilating both Covenant and humans into their ranks and you start to wish you just had the Covenant to face again.
** In ''VideoGame/Halo5Guardians'', it becomes clear that the Covenant remnant are small fry compared to the various Forerunner machines coming out of hiding and being controlled by [[spoiler:Cortana and the Warden Eternal]].
* In the ''VideoGame/SoulReaver'' series, the initial protagonist Raziel begins by being transformed from a vampire to a wraith which feeds on the souls of vampires.
* In the WebGame ''VideoGame/{{Amorphous}}'', the opponents you face are [[BlobMonster Glooples]], a number of which can engulf the player or eat him. Then there's the Amalgam, who like its namesake suggests can absorb other Glooples to become stronger. Of course, the Amalgam can engulf the player too if they're not careful.
* In ''VideoGame/MetalSlug 6'', the Mars People (from 2/X and 3) make a return, allied again with [[BigBad General Morden]] and his soldiers. Then they're attacked by the Venusians, who not only make short work of Morden's soldiers, but also literally ''eat the Mars People for breakfast''.
* In ''Videogame/DragonAgeOriginsAwakening'', the Children are introduced devouring normal Darkspawn and instantly transforming into bigger and more monstrous forms.
* The VillainProtagonist [[HordeOfAlienLocusts Eater]] from ''VideoGame/ChimeraBeast'' is on ''both'' ends of this trope. In the final level, it encounters smaller Eaters that it can consume and assimilate the abilities of. The final boss on the other hand is an ''even larger'' Eater that's trying to consume the player's.
* In ''VideoGame/VampireTheMasqueradeBloodlines'', even Nines, the badass leader of the Anarchs vampires, is terrified of werewolves. [[spoiler:The one you have to deal with in Griffith Park near the endgame can kill you in four or five hits, and shrugs off even your most powerful weapons -- [[PuzzleBoss you need to find a special way to kill it]]]].
* In ''VideoGame/ChronoTrigger'', if you fight against Edible Frogs and a Fangtooth, the Fangtooth eats one Edible Frog every time it is hurt to restore its health.

[[folder:Web Comics]]
* Vampires are extinct in ''Webcomic/DanAndMabsFurryAdventures'', as they had more powerful competitors like [[HornyDevils Cubi]], and the [[YourVampiresSuck nasty, inconvenient weakness against sunlight]].
* Goes one step further in [[http://partiallyclips.com/2003/11/30/bounty-hunter/ this]] ''Partially Clips'' comic. A BountyHunter seeking to join an EvilOverlord's forces is informed that [[CardCarryingVillain he needs to meet a certain standard of evil]] to join said overlord's armies. As a comparison, he's told of the Pnuxi, "a race so evil that they eat only sentient beings... which eat '''other''' sentient beings". [[UpToEleven The bounty hunter remarks that they sound delicious]].
* ''Webcomic/GirlGenius'': In [[http://www.girlgeniusonline.com/comic.php?date=20060501 one]] comic, as the main characters are heading through the sewers of Sturmhalten, Lars has to explain to their guides that most sewer systems aren't, in fact, infested with monsters. The guides express incredulity at sewers that aren't crawling with {{giant spider}}s, sewer serpents, [[OurGhoulsAreDifferent ghouls]], [[RodentsOfUnusualSize giant glowing rats]], giant squid and the like... because then what do the ''big'' monsters eat?

[[folder:Web Original]]
* On the Website/{{Bogleech}} website, the ''{{WebOriginal/Mortasheen}}'' series includes the [[http://scythemantis.deviantart.com/art/Mortasheen-Vaccuthax-101491269 Vaccuthax]], an EldritchAbomination that eats only vampires.
* The PointAndClick game [[http://armorgames.com/play/192/monster-basement Monster Basement]], it's revealed that the monster that kidnapped you enjoys eating other monsters. [[spoiler:Including you]]. This is expanded on in [[http://armorgames.com/play/2340/monster-basement-2 Monster Basement 2]], where not only do you find a cute little girl's diary entries about how her daddy fixes such tasty monster dishes, but one of the family members can be seen in the kitchen, messily chopping up another monster for dinner. [[{{Squick}} if you visit the outhouse after he uses it]], [[NauseaFuel you can find remains of the monster there]].

[[folder:Western Animation]]
* In ''WesternAnimation/TheSnorks'', the main characters had to deal with a predatory species called Snork Eaters once in a while, but in one episode they introduced another character who was a Snork Eater Eater.
* An episode of ''WesternAnimation/{{Futurama}}'' dealt with a "Sub-Sewer Mutant" that the regular Sewer Mutants feared. They try to laugh it off as just a Sub-Urban Legend.
** Though the mutants don't really fit this trope because they don't prey on humans.
** In the non-canon comics, there really are Sub-Sewer Mutants except they act really peaceful, it's only that [[spoiler: they mean the opposite of what they say]].
* A ''WesternAnimation/RobotChicken'' Charlie Brown sketch has a predatory Great Pumpkin being eaten by the Kite Eating Tree
* One episode of ''WesternAnimation/TheRealGhostbusters'' featured Mee-Krah, an EldritchAbomination that awoke every thousand years and devoured other ghosts in order to replenish its energy. Unfortunately, it became incredibly hot as it did this, until it eventually reduced the surrounding landscape to a wasteland. The Sahara Desert, the Gobi Desert, and Death Valley were all in their current state because of this demon's previous rampages. The heroes had to stop it before it did the same thing again (and it ''wasn't'' easy).
* In ''WesternAnimation/TheAmazingWorldOfGumball'', when Gumball and Darwin get lost in the [[IDontLikeTheSoundOfThatPlace Forest of Doom]], they attempt to eat a caterpillar out of hunger. Unable to go through with the deed, they release it and shout encouragement as it slithers away. Suddenly, a fish-bird creature swoops down and grabs the worm. The bird then gets eaten by a tentacled mouse monster, whereas the it gets eaten by a one-eyed gryphon. The gryphon, in turn, gets eaten by a huge moose-like beast. All of this happens in the span of 20 seconds, and Gumball and Darwin stare in silent horror as it goes on.
* A similar joke appears in ''WesternAnimation/BlackDynamite'': a white hunter is eaten by a giant white wolf is eaten by a larger white dinosaur is eaten by an even larger spider which Black Dynamite shoots in the head.
-->'''Black Dynamite:''' ''That'' is how you conserve ammo!

[[folder:Real Life]]
* Although physically incapable of ''eating'' humans, cobras and kraits on the Indian subcontinent do kill them with some frequency. These venomous serpents are also preyed upon by king cobras, which are specialized snake-eaters.
** The New World version might be the mussarana, a large colubrid that likes to eat rattlesnakes. Of course, it's not particularly dangerous to humans itself, though it ''is'' a rather intimidating-looking snake.
** Don't forget mongeese.
* Great white sharks, frequently regarded as ferocious man-eaters, are themselves easy game for orcas. Records have sharks leaving their feeding grounds whenever they felt a killer whale nearby. One recorded example had them go all the way from the mainland U.S. to ''Hawaii''. To put that in perspective, if they went the other way to Kansas, it wouldn't be ''far enough''.
** While coastal great whites live mostly on marine mammals, their open-water fellows regularly prey on smaller species of shark. This includes other notorious man-eaters like tiger sharks or oceanic whitetips.
* [[PantheraAwesome Siberian tigers]] hunt {{bears|AreBadNews}} (black and brown) and keep wolves in their territory at a minimum. Interestingly, of the three the tiger is the least likely to kill humans.
* Lions are afraid of crocodiles when they are in the water, but if they surprise them on land they will kill and eat them with no problem.
** While in water, however, crocodiles are afraid of hippos, whose only real enemy are human hunters.
** Lions tend to go out of their way to kill other predators in the areas they hunt: hyenas can fight back but leopards and cheetah are a bit out matched and have to avoid them whenever they can.
** Even lions run for it when African honeybees get riled up, having no means of defense against their highly-aggressive swarms.
* A certain urban legend holds that the benevolent [[https://en.wikipedia.org/wiki/Pholcidae cellar or daddy-long-legs spider]] (that long-leggity beastie that lurks in ceiling corners and vibrates when you get too close) has the most potent venom of any spider, but can't bite through human skin. The Food Chain of Evil is one possible explanation: cellar spiders prey on other spiders, including black widows, ergo cellar spiders must be even ''worse''. However, this is untrue, as the daddy-long-legs spider's fangs are perfectly capable of penetrating human skin and their venom is both extremely weak and injected in such small quantities that it has no effect on humans.
