* Inverted in the ''WesternAnimation/LooneyTunes'' cartoon ''WesternAnimation/LifeWithFeathers'' where a lovebird is so depressed after his wife leaves him (on the logic that lovebirds mate for life) that he tries to commit suicide by feeding himself to Sylvester (incidentally, his first appearance). Sylvester, in turn, concludes that there has to be something wrong with the bird and refuses to eat him in case he's poisonous. The bird pursues Sylvester relentlessly through the cartoon. The same plot was then used in the cartoon ''Cheese Chasers'' where Hubie and Bertie, having eaten so much cheese they can't stand it anymore, try to feed themselves to Claude Cat. Like with Sylester, Claude refuses to eat them figuring something's wrong with them, but they persist to the point he can't eat them or any other mouse, so ''he'' then goes and tries to get the bulldog to massacre him. It ends with the bulldog unable to take it and running after a dog catcher truck...with Claude chasing the dog...and Hubie and Bertie chasing Claude.

* In [[Myth/ClassicalMythology Greek Mythology]], Laelaps is a hunting dog which never failed to catch what she was hunting. When Cephalus decided to use her to hunt the Teumessian Fox, which could never be caught, the chase went on until Zeus decided to turn both to stone and put them to the sky as constellations Canis Major and Canis Minor.

* Somewhat {{Subverted}} in ''ComicBook/TheNewFrontier'', where the ''T. rex'' that "welcomes" ComicBook/TheLosers to Dinosaur Island decide they're not worth hunting after they blow its arms off with bazookas and grenades. Nevertheless, they succumb to DwindlingParty on the island anyways, and the following day the one survivor [[spoiler:deliberately baits the Rex into coming for him again, [[TakingYouWithMe with a grenade]] in each hand]].

* ''WebOriginal/ProtectorsOfThePlotContinuum'': The MarySueHunter agents of the PPC are required to have ImplacableMan tendencies by default, because the Suvians they hunt are a threat to the multiverse and ''will'' wreak continuous havoc if left unchecked -- it's all in the job description, even. Several missions cover entire ''series'' of badfics, with the agents sent into them pursuing their target throughout each installment until the Suvian is caught. Where this trope comes in is the fact that some agents ''eat'' Suvians, usually vampires who employ [[VampireBitesSuck the typical method]]. It's been stated a few times that because Suvians are {{Humanoid Abomination}}s, there are far fewer ethical concerns than if the agents were preying on actual human beings.

* Birds like seagulls, crows and caracaras really like to obsessively harass specific targets over long periods of time.

** The [[https://en.wikipedia.org/wiki/Tsavo_Man-Eaters Tsavo Man-Eaters]], a pair of maneless Tsavo lions, killed/consumed between 35/135 Indian laborers working on the Tsavo railway bridge in British East Africa. Even lighting campfires and building redoubts out of thorns didn't stop them. Eventually, Col. John Henry Patterson, a real-life GreatWhiteHunter, set off to kill them. He shot the first, but it escaped, then started stalking him. He shot it four more times, and it eventually died of its wounds. He found it lying dead in an ambush position where it had been waiting for him. He ambushed the second lion, shooting it five times. ''[[{{Determinator}} It got up and charged him.]]'' Three more bullets put it down. Patterson claimed it died trying to leap over a fallen tree branch, ''still trying to charge him.'' [[WhosLaughingNow Then they spent 25 years as a rug.]] A modern analysis of the attacks shows that the lions may actually have been an ''aversion'' to the trope: the reported attacks were all during the dry period when the lions' normal prey was scarce. During the rainy season, when herd animals were more common, they actually stopped attacking humans. These two were more recently turned into a museum exhibit (with one of them lying down, since the rug didn't include his belly). See the Movies entry for the movie based (somewhat loosely) on the event.

** [[http://en.wikipedia.org/wiki/Gustave_(crocodile) Gustave]] was infamous, even if much about him remains uncertain. What's scarier than an enormous Nile crocodile? An enormous Nile crocodile that not only has a taste for eating humans, but enjoys torturing them too. He was believed by some to be nearly 70 years old, and, thanks to hundreds of human corpses dumped in the Rizizi river during Burundi's civil war, he has a taste for ''Homo sapiens''. He was often rumored to have killed nearly 300 people, and according to locals, doesn't eat them all -- he kills because he enjoys it. Albeit much of this information is unsubstantiated. A National Geographic expedition tried to capture him using a steel cage and a live goat. After the camera went out one stormy night, they found the cage the next morning, the goat gone, smashed to pieces at the bottom of a lakebed. So what makes him "super-persistent?" Well, apart from his enormous size, his other distinguishing features are machine gun scars, a grenade wound, and ''having an enormous bullet hole in the middle of his face.''
* Komodo Dragons are often said to fit the bill; the scenario said to be that they first take a bite out of their prey, and through a combination of mild anticoagulant venom (ie, the wound bleeds out) and severe laceration from the teeth, it's only a matter of time before the animal drops from blood loss, trauma, paralysis, and infection. And if it doesn't die in minutes, the dragon will attack again and again until it drops. Most popular depictions have long-distance tracking as the norm, but in reality studies have shown they simply keep chasing and biting it until it falls, provided that it is not too difficult to do so. They also usually shred the legs and ankles to keep prey from running. If the animal actually puts a good amount of distance between it and the dragon the dragon will give up (though another dragon may take advantage of the injured animal later), the dragon won't track it far at all, and most animals that escape heal just fine.
* Some paleontologists believe that many large predatory dinosaurs may have practiced this method of killing as well. This is really the only way to kill giant sauropods, which are simply too dangerous to kill by any other method of attack- one (or possibly more) big therapods would stalk a sauropod until they spotted an opening to run in and take a bite out of its vulnerable belly or flank. This created a large, bleeding wound. Continuing to harry it over a course of hours, days, or possibly even weeks would eventually cause it to die of a combination of exhaustion, blood loss, and possibly infection. Tyrannosaurs and spinosaurs, however, not being sauropod hunters, were physically incapable of hunting this way.

* While herons and their close relatives, the egrets and bitterns, generally don't chase after their prey, their persistence comes from their impressive patience. Herons will spend prolonged periods of time standing perfectly still, waiting patiently for hours on end for their prey (usually fish, but also small mammals and waterbirds) to come close, then in an instant seize them with great speed and force.

** They can also identify and remember individual people and are capable of both incredible gratitude and spite.

* Komodo Dragons are often said to fit the bill; they first take a bite out of their prey, and through a combination of mild anticoagulant venom (ie, the wound bleeds out) and severe laceration from the teeth, it's only a matter of time before the animal drops from blood loss, trauma, paralysis, and infection. And if it doesn't die in minutes, the dragon will attack again and again until it drops. Most depictions have long-distance tracking as the norm, but in reality they simply keep chasing and biting it until it falls, provided that it is not too difficult to do so. They also usually shred the legs and ankles to keep prey from running. Normally if the animal actually puts a good amount of distance between it and the dragon the dragon will give up (though another dragon may take advantage of the injured animal later).

* Some paleontologists believe that many large predatory dinosaurs may have practiced this method of killing as well. This is really the only way to kill giant sauropods, which are simply too dangerous to kill by any other method of attack. Tyrannosaurs and spinosaurs, however, not being sauropod hunters, were physically incapable of hunting this way.

** We have the big antagonist of the film, [[spoiler:Rudy (though his case may be justified, seeing as he's out for vengeance against a rival among the protagonists as well as just a meal)]]

* A ''WesternAnimation/RobotChicken'' sketch involving WesternAnimation/TheSmurfs getting killed in a flood has Gargamel, after years of trying to capture the Smurfs so he can eat them, finally being able to eat them (what with so many Smurf corpses). When he takes a bite though, the look on his face is that of "I've wasted my life". (In [[ComicBook/TheSmurfs the original comics]], he doesn't want to eat them (Azrael does), but use them as ingredients to create a philosopher's stone.)

* Tom of ''WesternAnimation/TomAndJerry'', whose obsession is best relayed through the fact that he once chased Jerry into a ''dog pound''. This is mostly {{justified|Trope}} as Tom chases Jerry less out of hunger and more out of a desire to get even. Even when Tom's original intention was eating Jerry, he only really becomes persistent when Jerry sufficiently humiliates or injures him.

** The panther in ''[[WesternAnimation/GarfieldSpecials Garfield in the Rough]]'', which attacks them at their campsite and ''smashes the driver-side window of Jon's car with its head'' (taking two tries to break it), then turns to go after Garfield after he drops on its back and claws and bites the panther.

** The pack of hungry pterosaurs. No matter what happened, wether it was passing around brachiosaurus legs, being bombarded by exploding fruit bombs, or trying to outsmart Buck’s steering, they were determined to eat Crash and Eddie throughout.
*** One pterosaur in the pack takes the hunt further by thinking to dodge all the fruits the others have been knocked down with, then without any hesitation, breaks away from the others to fly up at the possums and scare them with its fierce screech. This extreme persistence of the pterosaur ultimately backfires for him.

** ''Literature/TheWayOfKings'': Discussed when a [[{{Kaiju}} chasmfiend]] gets loose to attack the king's party during a hunting trip. Dalinar points out that they could retreat and allow the monster to feed on the party's animals, but the king wants a glorious battle. Once it has taken enough damage, it goes into a blood rage, and Dalinar notes now that it would chase them for miles if they tried to retreat.

** The pack of hungry pterosaurs. No matter what happened, wether it was passing around brachiosaurus legs, being bombarded by fruit, or trying to outsmart Buck’s steering, they were determined to get Crash and Eddie for a meal.

* ''Literature/{{Animorphs}}'': In one of the ''Megamorphs'' books (a special event book in which all six characters narrate), they are transported [[TimeTravel back in time]] and find themselves battling a Tyrannosaurus Rex. While fleeing, they morph to escape, and Marco morphs into an osprey, his standard bird choice, that has both the ability to fly and should logically be too small to keep the predator's attention. However, instead of giving up once the already-small meal becomes an even ''smaller'' meal, as Marco logically expects it to do, the dinosaur keeps chasing him, and actually begin to ''tear apart trees that are standing in the way''. Marco ultimately realizes that food has stopped being the point of the chase, and that the Rex is chasing him out of pure blood-lust and rage.
* ''Literature/ArtemisFowl'': Justified with Trolls. To them, humans are by far the most delicious things ''ever''; after trying one, a troll will do ''anything'' to eat more. Also, as subterranean predators, they have ''extremely'' finely-tuned senses, so that exposure to the surface tends to cause them sensory overload which causes severe brain damage, usually removing most of their survival instinct.

** we have the big antagonist of the film,[[spoiler:Rudy (though his case may be justified, seeing as he's out for vengeance against a rival among the protagonists as well as just a meal)]]

* One ''Manhua/OldMasterQ'' comic have the titular character boating near a beach when he's attacked by the shark. He managed to escape by rowing like crazy, all the way back to the shoreline, and as Master Q gets on land while BlowingARaspberry at the shark, suddenly said shark comes out of the sand in front of Master Q, LandShark-style.

* The xenomorphs of ''Franchise/{{Alien}}'' will hunt down and kill (or capture for [[FaceFullOfAlienWingWong impregnation]]) anything and everything near them. One theory raised by those making the movie was that the aliens were created as weapons of war, so that would also make their actions plausible. The prequel ''Film/{{Prometheus}}'' justifies the xenomorphs' persistence with TheReveal [[spoiler:that they are merely a by-product of the Engineers' bio-weapon. Like everything else spawned from the black goo, the xenomorphs' only purpose is to [[OmnicidalManiac wipe out all life]]. ''Film/AlienCovenant'' further establishes that modern-form xenomorphs are specifically a result of David's experiments mixing this chemical with the embryo of a parasitic wasp-like lifeform native to the Engineers' home planet]].
* The aliens in ''Film/AlienAbduction2014'' seem to be pretty insistent on getting all of the Morris family, though it isn't clear where it's the same group of aliens chasing them the entire time, or if they keep encountering different groups that are all hunting on Brown Mountain that night.
* ''Film/{{Anaconda}}'' combines this with ArtisticLicenseBiology, stating that the anaconda is some kind of BloodKnight that enjoys killing '''so much''' that it will regurgitate its latest meal just so it can hunt and kill again. Needless to say, no real reptile would waste energy like that. Anacondas and other giant snakes were once ''[[ScienceMarchesOn thought]]'' to do that, but it turns out they only regurgitate their food if they're overly threatened while lethargic (btw, the snake in the movie should find a safe place and go into a self-induced ''coma'' after eating just one guy, nevermind a whole boat), or because they're, y'know, getting sick off it. Strangely, the movie also at least partially ''{{justifie|dTrope}}s'' this trope due to the fact that the protagonists in question spend pretty much their entire time in the anaconda's territory hunting ''it'', so its actions could come off as self-defense, aforementioned BloodKnight tendencies aside, as well as the fact [[spoiler:there's more than one giant anaconda.]]
* ''Film/AnacondasTheHuntForTheBloodOrchid'': Played with. The jungle expert notes that there's no way a single anaconda, even a giant one, is going to pursue the others after already eating one of them. However, the film justifies the trope by explicitly featuring a large group of hungry snakes who are all in the same area because of a mating season and the humans simply cannot avoid running into them. The travelling male snakes are hyper-aggressive for the same reason.
* The Film/SyFyChannelOriginalMovie, ''Film/AttackOfTheSabretooth'', gives an unusual justification for why the titular beasts keep hunting people even after they'd realistically be full. They're ''bulimic'' and keep regurgitating everything they eat so they're always hungry. How and why a bunch of prehistoric big cats all have psychological eating disorders [[VoodooShark is a whole other can of worms, however]].
* In the shark horror film ''Film/Bait3D'', the sharks persistently hunt the surviving humans. It becomes more believable at the end when it's revealed that [[spoiler:the sharks were actually ''trapped'' in the convenience store along with the people and couldn't just swim away]].
%%* The wolf in ''[[Film/{{Benji}} Benji The Hunted]]''.
* The trailer for ''Film/Beast2022'' has a safari guide lampshade how out of character this is for a lion, implying that it's no ordinary predator. It later turns out the lion attacks humans out of anger after poachers killed its pride.
-->''"I've never seen anything like this: multiple kills, without eating its prey."''
* The paperboy in ''Film/BetterOffDead'', who pursues Lane on his bicycle throughout the whole movie to get the two dollars he owes him. Highlights include apparently multiplying in one chase until there's half a dozen identical paperboys chasing him, chasing him in the middle of the climactic ski race between Lane and [[JerkJock Roy Stalin]] (''still'' on his bicycle while wearing skis,) and even rushing him and Monique in the last few seconds of the final FlyawayShot of the movie.
--> '''Paperboy''': [[CatchPhrase I want my two dollars!]]
* ''Film/BloodSurf'': The crocodile pursues the main characters all the way through a jungle just for a chance to eat them.
* The Tiger in ''Film/BurningBright''. Justified in that the Tiger was starved for nearly a week, and there was no other food supply.
* The cannibals of ''Film/TheColony2013'' never stop, despite the fact that chasing the protagonists is killing them off quickly. Perhaps justifiable since they really have no other source of food.
* An inversion in ''Film/CoolHandLuke'': when Luke escapes prison, he runs so persistently that the bloodhound trailing him runs itself to death.
* In ''Film/{{Crawl}}'', real alligators would generally try to find somewhere sheltered to hunker down during a hurricane, not go hunting. However, [[spoiler: the gators are shown to have built a nest in the basement, so not only are they hungry, they also have eggs to defend]].
* Justified in ''Film/{{Crocodile}}'' (but not so much the [[Creator/{{Syfy}} Sci-Fi]] [[Film/SyfyOriginalMovie Original]] sequels third and onward), featuring a crocodile ([[AttackOfThe50FootWhatever giant, naturally]]) pursuing a group of half-dressed teenagers. One of them had one of her eggs in his backpack, fueling her maternal rage. The survivors are allowed to leave when they return it. However, while real life crocodiles actually do have [[CubCuesProtectiveParent fairly strong protective instincts]], they wouldn't chase after someone, and if a nest robber got away from it, it's not going to bother to chase it down.
* The sharks in ''Film/DeepBlueSea''. Tom Jane even points out that sharks don't particularly like the taste of people. Justified because [[spoiler:eating the people isn't the goal; getting them to open doors and flood the facility is. Although wiping them out is a beneficial bonus since [[LeaveNoWitnesses no one else would know]] about the super intelligent sharks]]...
* The sea worms in ''Film/DeepRising'', who continue to relentlessly pursue the heroes despite suffering extreme gunfire trauma from doing so every time. [[spoiler:Although the fact the opening of the movie shows an underwater graveyard littered with ships and whale skeletons implies the creature isn't indiscriminate on what it eats and has made a habit of snacking on human ships for quick meals. Since the "worms" are really the tentacles of a scarily intelligent octopoid, it's possible the creature correctly sees the gun-toting humans as a threat to be eliminated more than a meal.]]
%%* The bear in ''Film/TheEdge'' was a perfect example of this trope.
* This trope is the premise of ''Film/TheGhostAndTheDarkness''. This is also a true story; the lions are stuffed and on display in the natural science museum in Chicago. Later studies have suggested that between the two lions, they only ate some 40 people; still a lot, but not the 140 originally claimed.
* PlayedForLaughs in ''Film/TheGodsMustBeCrazy II'', in which the predator is the small honey badger and the prey is a guy (and later, his boot).
* The baby Zillas in ''Film/{{Godzilla 1998}}''. As newly hatched animals, not only should their first priority be to feed themselves, which is easy given the abundance of available fish, but they should be starving and exhausted from the effort of hatching. Worse, they all start competing over an incredibly small number of people to eat (even at some points seeming to start fighting among themselves over who gets to eat the people). Actually justified, as all fish is gone by the time they start chasing humans (who smell like fish).
* In ''Film/{{Godzilla 2014}}'', [[Characters/MonsterVerseGodzilla Godzilla]] tracks the [=MUTOs=] from one side of the Pacific to the other. {{Justified|Trope}} [[spoiler:considering Godzilla considers the entire Earth its territory and the [=MUTOs=] are an active threat to the biosphere, as well as the fact they're explicitly parasitoids which utilize his species as a host, so he has a ''personal'' reason to prevent them from breeding (outside of fighting each other just being what kaiju do naturally)]].
* ''Film/TheGrey'' features a pack of SavageWolves as a central plot point. Justified, because [[spoiler:the humans were unknowingly moving deeper into the wolves' territory. The [[FinalGirl last guy]] finds himself in their den]].
* It from ''Film/ItFollows'', the closest definition of the trope that you can get. Once it targets you, it never gives up. It will always hunt you and will always find you. It cannot be killed or trapped. The only way to stave it off, is to have sex with someone else, but when It targets and kills them, it comes right back after you... That said, it's definitely a supernatural monster so it's justified.
* While the shark in ''Film/{{Jaws}}'' is not much of an example, as it behaved much like an actual predator, the sequels play this very straight. Taken to ludicrous extremes in ''Film/JawsTheRevenge'', apparently tracking down people over [[VoodooShark hundreds of miles]] (while our protagonists are ''in an airplane'') in order to kill them in revenge for their father having killed a couple of other sharks a decade earlier. The novelization claimed this was due to an unexplained Voodoo curse, thus naming the VoodooShark trope.
* The ''Franchise/JurassicPark'' franchise plays around with this trope, particularly with ''Tyrannosaurus rex'' and ''[[RaptorAttack Velociraptor]]'':
** ''Film/JurassicPark1993'':
*** The ''T. rex'' only seems to play it straight when she's chasing the jeep at a suicidal speed for her species, but it's quickly subverted when the jeep accelerates beyond 30 MPH and she soon gives up the chase. Given that she only kills one human and spends most of her time hunting other dinosaurs, it is possible that she's not really hunting humans for food as much as she's establishing new territory for herself and chasing away potential rivals.
*** The ''Velociraptors'', on the other hand, are portrayed as vicious killers that need to be locked away in a cage. They always try to break out of their enclosures, and specifically targets humans as their preferred choice of prey. It's also implied that, due to their intelligent brains, [[ForTheEvulz they hunt for sport]], explaining why they still pursue the surviving humans even after killing enough prey to feed them for the day.
*** Unusually, the original film shows both the ''T. rex'' and the raptors losing all interest in humans when the chance to attack a '''rival''' predator, i.e. each other, comes along. As both had recently eaten, territoriality trumped hunger.
** ''Film/TheLostWorldJurassicPark'':
*** Justified with the ''Tyrannosaurus'' couple as they are chasing the humans [[MamaBear because they had kidnapped their baby]], and [[TooDumbToLive one of them is still walking around in clothing smeared with their infant's blood]].
*** A flock of ''[[KillerRabbit Compsognathus]]'' is willing to attack a full-grown man and chase him to the point of exhaustion until he's too weak to fend them off when they tear him to shreds, but they only do this when he's separated from the rest of the group, unarmed, and injured from a fall. The group's paleontologist actually lampshades the little dinosaur's aggressive nature, stating that with no human contact for years, the compys have no reason to fear humans.
*** The ''Velociraptors'' are again vicious brutes determined to hunt every human in their vicinity though this time there is a legitimate reason for it. In order to get off the island, the protagonists need to get to an abandoned facility in the island interior and radio for rescue. The problem is that the facility area is also raptor territory and humans are easy prey for them, especially when disorganized.
** ''Film/JurassicParkIII'':
*** The ''Spinosaurus'' chases the protagonists about a mile farther than reason would allow. According to the filmmakers it was on a RoaringRampageOfRevenge after they [[MinorInjuryOverreaction clipped it with their plane while trying to escape from it]].
*** They also stumble upon a ''Tyrannosaurus'' eating a dead dino with plenty of meat left, but when it sees the humans, it naturally starts pursuing them instead. Which incidentally leads it to the ''Spinosaurus'', whom [[SpinosaurusVersusTRex it engages]] and [[TheWorfEffect is killed by]]. It might have perceived them as a threat to its meal and is chasing them off ... in which case it ought to have ''stopped'' chasing them as soon as they were out of sight and gone back to its food.
*** The ''Velociraptors'' of this film, however, chase the heroes because [[spoiler:one of them [[TooDumbToLive secretly steals their eggs]]. When the eggs are returned safely, they leave without attacking]].
** ''Film/JurassicWorld'':
*** The film justifies the ''Indominus rex'''s persistence by establishing that she's a hyper-aggressive super-predator that is killing for ''[[ForTheEvulz sport]]'' rather than for ''food''. However, in one scene, the ''I. rex'' gives up on chasing a pair of human children because they jumped over a waterfall and swimming is seemingly the one thing she is unable to do.
*** An overly eager ''Pteranodon'' tries to fish out Zara from the lagoon with the intent of eating her despite the fact that she, as a full-grown woman, is too heavy to be lifted with its beak. [[spoiler:The constant splashing eventually attracts a ''[[AlwaysABiggerFish Mosasaurus]]'' who proceeds to eat both Zara and the ''Pteranodon'' in one swift bite.]]
*** The ''Velociraptors'' here have been tamed into a manageable squad by Owen Grady, but are still dangerous and will attack any stranger or human they simply don't like. But they're not single-mindedly focused on hunting down all humans [[spoiler:until the ''Indominus rex'' usurps Owen's authority and commands them to kill their human allies. From that point, the raptors begin pursuing every human they can find, including a fast-moving jeep heading all the way down to Main Street.]]
** In ''Film/JurassicWorldFallenKingdom'', the predators in Isla Nublar seem to place their hunger above their basic survival instincts:
*** Even as Mount Sibo showers the island with flaming rocks, a ''Carnotaurus'' takes its sweet time hunting a ''Sinoceratops'' and Owen instead of joining the stampede.
*** Rexy herself ignores the volcanic eruption at first to attack the abelisaurid, thus keeping up the trend of her being an AccidentalHero.
*** The ''Baryonyx'' chases Claire and Franklin into a shelter that is being filled up with lava, not giving up on its prey even after being burned in the face. This is specially jarring when the official website mentions the ''Baryonyx'' as a species is only mildly aggressive and used to be part of an attraction where visitors would go kayaking at its territory.
*** The only justified example is the ''Indoraptor'', which is a successor to the ''I. rex'' from the previous movie and is just as ruthless and sadistic as she was.
*** The film later zigzags the trope when the carnivores and herbivores completely ignore each other upon [[spoiler:being released into the garage of Lockwood's estate, as one would expect from a group of animals that are more concerned with avoiding being poisoned by a damaged ventilation system]].
** ''Film/JurassicWorldDominion'' has an engineered case in the ''Atrociraptor'', which is a successful attempt at a trained killer dinosaur that the above mentioned ''Indoraptor'' was supposed to be. And 'persistent' is the key word, as once it is assigned a target, ''Atrociraptor'' will pursue it even as it rides motorcycles and cars, and through rooftops and cramped rooms.
* While all of the predators of Skull Island in ''Film/KingKong2005'' seemed to want to try out the new taste sensation of white people more than the next one, none were worse than the ''V. Rex'' who actually runs after Ann Darrow ''with the corpse of a current kill in his mouth''. Some of the V. Rexes on the island actually ''sacrifice themselves'' in their attempts to kill her. And when given the chance to bite Kong versus swallowing Ann, they always went for Ann. The ''Venatosaurus'' [[RaptorAttack raptor]]-pack comes a close second, trying to chomp humans in the middle of a ''Brontosaurus'' stampede, then persisting in chasing down hapless cameramen, rather than gorging on several thousand tons of fresh bronto meat that was lying there waiting for them.
* Justified in ''Film/{{Komodo}}''. The komodos relentlessly pursue the protagonists, but there are several of them and they are stated to be starving. The behavior may also have been inspired by the outdated belief that ''real'' komodo dragons do this, namely bite large prey and then follow it relentlessly until it keels over from infection and venom. This has since been indicated to not be the dragon's actual hunting strategy. Normally if a animal escapes a komodo dragon then it's a failed hunt for that dragon. Another komodo may take advantage of the injured animal later, but the original isn't going to bother tracking an escaped animal very far. Typically komodos kill their prey relatively quickly via massive blood loss and perhaps help from the venom. Even the infection strategy may be more coincidence than intention (injured water buffaloes retreat to dirty water that causes their wounds to become infected, but the infection is not intentional on the part of the dragon).
* ''Film/KongSkullIsland'': The [[Characters/MonsterVerseSkullIslandKaijuAndOtherCreatures Skullcrawlers]] on Skull Island are literally called the "persistent enemy" in the Iwis' language, never stopping once they've targeted prey due to their HorrorHunger.
* Justified in ''Film/LockjawRiseOfTheKulevSerpent''. Lockjaw is a giant snake [[MixAndMatchCritters with the head of an alligator]]. As a magical spirit of vengeance, it will not stop once it has been summoned until it has killed those it was summoned to punish.
* Played with in the 2009 ''Film/LandOfTheLost'' movie. The resident ''T. rex'', Grumpy, actually ''is'' all set to give up on chasing Marshall, Will, and Holly after they prove to be more trouble than they're worth. That's until Dr. Marshall insults the ''T. rex's'' intelligence, causing it to hold a grudge against him for the rest of the film. Marshall keeps insulting it several more times, just as it seems the ''T. rex'' is ready to give up, fueling the creature's rage.
* TV BMovie ''Film/TheLastDinosaur'' has the titular titan, a ''T. rex'' with ImplacableMan tendencies, treat a group of explorers like this ... at first. Then we see it kill and eat everything unlucky enough to cross its path. Implicitly, it's eaten most every other animal in the LostWorld.
* In ''Film/TheMeg'', the [[spoiler:second]] Megalodon pursues the protagonists' motorized dinghy for over ''ten miles'' before a couple of attack helicopters finally drive it off.
* In the A24 horror film ''Film/TheMonster2016'', the titular beast kills just about everything it comes across, even when it has no realistic reason for doing so. It starts the movie by snacking on a wolf and proceeds to kill and eat a grown man before setting its sights on the mother and daughter protagonists. It then kills two paramedics and continues chasing the protagonists when they try to drive away from it. After a while, it seems like everything it does may simply be ForTheEvulz.
* The killer whale in ''Film/OrcaTheKillerWhale''. {{Justified|Trope}} in that it was out for revenge, something dolphins regularly do in RealLife, though in the film it was portrayed as a male avenging his mate and child (making it more like an aquatic ''Film/DeathWish'' than a ''Film/{{Jaws}}'' imitator) when in reality it would be a whole pod avenging one of their friends.
* Onibaba in ''Film/PacificRim'' was very determined to kill a young Mako. It's implied, though, that being a memory, this scene wasn't meant to be a literal retelling of events but rather the skewed representation of a scared little girl in the middle of a {{Kaiju}} attack. Though it would be justified, since the kaiju [[spoiler:are not natural predators, but bioweapons created solely to wipe out humanity. That means every single human, even a little girl, has to die]].
* The last stretch of ''Film/{{Prophecy}}'' has the main cast dealing with a literal (mutated) MamaBear that wants to get them no matter what.
* ''Film/AQuietPlace'': [[{{Tagline}} "If they hear you, they hunt you"]]. Often these hidden creatures, who are blind (and apparently don't have a sufficient sense of smell) but hunt by sound and are very fast and near indestructible, home in and strike very quickly if you make a noise -- but if you evade them, they'll still prowl around, listening very closely for further sound or movement, and not go away....
* ''Film/{{ROTOR}}'' revolves around the titular police KillerRobot accidentally activating and going on a rampage by following its primary program to be a JudgeJuryAndExecutioner. The full extent of said rampage is the implacable chase of a poor woman who was a passenger to his first kill (a {{Jerkass}} who was speeding) on the apparent charge of being an accomplice and resisting arrest, which covers several hundred miles of Texas backroads and takes at least one whole day.
* In ''Film/TheShallows'', the shark repeatedly attacks Nancy and kills several other humans who get into the water even though there is a whale carcass nearby. It is implied due to the scars on its face and the spear stuck in its side that it has had a bad history with humans and attacks them out of anger.
* ''Film/SharkAttack'': The sharks are intentionally (and as the hero -- who's a marine biologist -- notes, rather uncharacteristically) going after humans. This is initially thought to be because overfishing is driving them to look for prey at the shorelines, but it's later revealed to be because a guy with a MorallyAmbiguousDoctorate was spiking them with hormones.
* ''Film/StarTrek2009'': Used as {{padding}} in. Kirk is being chased by some shambling furry thing. Then a giant red animal with multiple limbs and a FlowerMouth bursts out of the ice, bites the furry thing, tosses it aside... and starts chasing Kirk. Even though the shambling furry thing was bigger (but still bite-sized to it) and it had already killed it. It also frequently stops to roar at Kirk. [[spoiler:Eventually, Spock Prime is able to run it off with a flare.]]
* Creator/JJAbrams is very fond of including these in his Sci-Fi movies. Like in the previous example, he invented Rathtars for ''Film/TheForceAwakens'', which are giant red tentacled blobs covered in yellow eyes with gaping maws full of teeth. They attack anything they can get their tentacles on with blinding speed. The general rule of an Abrams Sci-Fi movie is that he won't even look for an excuse to include a big red monster with tentacles and pincers and far too many teeth with a desire to rapidly chase the main character(s) [[RuleOfFunny just for kicks]].
* Oh boy, pick a Creator/SyFy "[[Film/SyFyChannelOriginalMovie Original Movie]]". To name a few of the more [[NightmareFail unintentionally hilarious]] examples:
** In ''Film/{{Kaw}}'', CreepyCrows get infected with [[TheVirus Mad Cow]] (?!) disease ''after'' eating clearly diseased rotting cow flesh. As soon as they go crazy, they decide to exclusively go for the human protagonists (not even any other areas, just those few people). This includes ''waiting on a bus'' while the humans cry and then ''throwing rocks'' at the bus in a desperate attempt to get inside. Later, they slam themselves against a diner in order to get in and eat the people inside, before they [[DeusExMachina inexplicably die]]. You'd think there weren't any animals in the forest. Subverted in that the super persistent predators starve to death, just as they would in real life.
** Shockingly averted in the (surprisingly good) reimagining of ''Film/{{The Land That Time Forgot|2009}}'' (which starred and was directed by '''C. Thomas Howell''') in which the Rex only chases the humans when they enter its territory to steal food, and all it does is just try to run them off.
** Used as a plot point in ''Film/{{Sharktopus}}'' -- one character wonders why the eponymous creature is going out of its way (such as attacking boats and ''going over land'') to attack humans rather than just hunt aquatic creatures, and it turned out [[JustifiedTrope there had been secret changes to its genome to make it a better killer]].
* The Graboids in ''Film/{{Tremors}}''. Earl compares their patience to that of Job. They track prey endlessly, and if the prey is somewhere they can't reach, they wait it out for ''days'' if need be. The only time they'll leave is when the prey dies of dehydration/starvation or if they're distracted by a sufficiently loud noise/vibration nearby that screams "easier meal" for them.
* ''Film/UltramanSaga'': Early in the film, there's a Gubila (a kaiju narwhal, imagine something like a LandShark) which relentlessly pursues Taiga and a little boy he befriended throughout the deserted city, from the streets to above a bridge, for maybe three minutes without stopping, even destroying said bridge just to catch two tiny humans.
[[/folder]]

[[folder:Video Games]]
* Certain players in most multiplayer [[PlayerVersusPlayer PvP]] games are like this, especially when time-to-kill is low. Get their attention and they will chase you constantly until you are within range and try to kill you. They'll even prioritize this over any game objective.
* Alma from the ''VideoGame/AdventuresOfLolo'' games. She'll normally mind her own business, but if Lolo should get within her field of vision, she'll roll after him until either she catches him or he takes refuge in a meadow.
* The good old xenomorph in ''VideoGame/AlienIsolation'', which will determinately chase Amanda Ripley across an entire gigantic space station, constantly showing up to plague her even if she's taken in-game traincar-like transport miles away. [[spoiler:Or, considering it is ultimately revealed there's a whole nest of aliens infesting said space station, she might just be encountering a whole bunch of them.]]
* While on the Frontier in ''VideoGame/AssassinsCreedIII'', you encounter wolves and {{bears|AreBadNews}} which attack you on sight. Contrary to what happens in real life, the wolves are super persistent and attack you... even after you kill their alphas. They don't retreat even when it's in their best interest. Possibly justified since it's a computer simulation in-universe rather than "real" wolves.
* Certain enemies in ''VideoGame/TheBindingOfIsaac'' such as Gapers and Globins do nothing but charge relentlessly at the player (and even after beating the latter, the player still has to destroy their remains to keep it from rising up again and resuming their charge.) Lust and Super Lust are the boss version of this, with more health and a much faster speed, to the point that characters with too low a speed stat just can't outpace them.
* ''VideoGame/{{Carnivores}}'', oh sweet mother of God, Carnivores! The T. rex in this game is practically the embodiment of this trope. Subverted without cheats, [[DemonicSpiders since your neck will be snapped long before the dinosaur has a chance to be super persistent]], but if you have debug mode on, then the T. rex will chase you over mountains, across plains and hills, through forests, and will even follow you ''into the frickin' ocean!''
* The giant... black... troll... thing, from ''VideoGame/CastleCrashers''. It just won't stop chasing you until it's dead, no matter how many arrows (or magic attacks) you throw at it.
* In ''VideoGame/ContagionMonochrome'', the [[EliteMooks Riot zombie]] is a zombie clad in bulletproof armor. It soaks up [[MadeOfIron bullets like a sponge does water]], and it is ridiculously persistent, chasing survivors throughout the entire map until it (the pursuer) is killed. They can be extremely difficult to deal with in harder difficulties where ammo is limited and zombies can kill in a minimal number of hits. The only easy way to get rid of it is to [[StuffBlowingUp blow it up with an explosive weapon]].
* The walrus chef in ''VideoGame/CrashTwinsanity'', who chases you halfway across N Gin's battleship -- over seemingly arbitrary holes in the floor, through walls of crates -- even ''nitro crates'' don't slow it down.
* In ''VideoGame/DarkestDungeon'', if you encounter the Shambler and run from it, it will turn up in every future encounter until you kill it, you leave the dungeon or it murders you. (If you had to run from the Shambler once, odds are strongly in favour of "it murders you", [[KnowWhenToFoldEm so that abandon button might start to look very tempting]].) {{Justified|Trope}}; the Shambler is an EldritchAbomination that dwells in a weird cosmic dimension and isn't bound by the limitations of the physical world, and so it's honestly fairly generous of it to stop pursuing you ''at all'' and not follow the adventurers into the Hamlet and mug them in their rooms at the Sanitarium or the brothel.
* Any regenerating Necromorph in ''VideoGame/DeadSpace''. They ''will'' hunt you, they are invincible and thus walking bullet sponges, their slow but unstoppable approach makes the player nervous, and they tend to be encountered in rooms with timed lockdown. Fortunately, you can get rid of them, just not so easily. Hunter, Übermorph, and Regenerators are stopped by [[spoiler:shuttle engine, outrunning, and blasting to pieces]], respectively.
* The T-Rex in ''VideoGame/DinoCrisis'' will never stop stalking you. Every time you encounter and defeat it, it'll just back off for a little while until it's ready to attack you again. Naturally, you put it down for good in the finale.
* Similarly, ''VideoGame/DinoStrikeWii'' has a T-Rex as it's last boss, who relentlessly comes after you after you empty what seems like a dozen grenades down it's throat. It takes an erupting ChekhovsVolcano finally [[AMoltenDateWithDeath drowning it in lava]] to finally kill it.
* ''[[VideoGame/DynastyWarriors Dynasty Warriors 8]]'' has [[TheDreaded the supremely powerful Lu Bu]] who, except in specific missions where the entire point of the mission is to defeat him, is always immensely buffed to the point of effortlessly crushing everything in his way. While he does come after your forces in certain missions, if Diaochan is on the same map and the player defeats her, Lu Bu will become so enraged that he'll enter his buffed state if he isn't already and specifically target the player for the rest of the mission, which is frequently followed by a swift and horrific death at his hands unless you can play keep-away long enough to complete the mission.
* ''Franchise/TheElderScrolls'':
** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' and its ''Bloodmoon'' expansion play this straight. Both Vvardenfell and Solstheim feature MorePredatorsThanPrey, and it's quite difficult to lose an enemy creature if aggro'd. However, the [[GoddamnedBats notorious Cliff Racers]] are even more difficult to lose thanks to their [[AirborneMook ability to fly]].
** ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'':
*** ''Every'' enemy is this. That mountain lion, that wolf, that troll, that ''rat''... will chase you down to the ends of the earth in order to maul/feast upon your flesh. They will come after you through villages, forests, rivers, lakes, mountains, and plains, from the farthest western point of the map to to the farthest eastern point, in an all-consuming, single-minded drive to wreak vengeance on you for entering their line of sight.
*** The King of Miscarcand (a powerful undead boss fought in the main questline) has the trademark persistence of an ''Oblivion'' enemy, but (due to a bug) he [[TheAllSeeingAI never loses track of the player's position]], and he's not afraid of entering crowded cities.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' keeps this tradition alive in the series. Predatory creatures including bears, wolves, and sabrecats ''will'' chase you halfway across Skyrim once aggro'd.
* ''VideoGame/EtrianOdyssey'': Once you've triggered an F.O.E. encounter, you won't get rid of it until you kill it or it wipes your party. Some F.O.E.'s are also programmed to start coming after your party as soon as you step foot into a dungeon, even if you haven't encountered it.
* The Monsters of ''VideoGame/{{Evolve}}'' are this in spades. Massive extraterrestrial predators at least as smart as humans, they have an almost pathological drive to hunt and kill people. Humans too well equipped to kill? They'll hide in the wilderness, feed on other animals, grow, and repeat until that's no longer true.
* The ''VideoGame/{{Fallout 4}}'' mission "The Devil's Due" introduces possibly the most persistent Deathclaw in history. Who tracks a group of Gunners across a huge swath of territory to [[spoiler:retrieve its stolen egg]].
* Being a fairly early MMO, mobs in ''VideoGame/FinalFantasyXI'' originally had no tethers. Once aggroed they would chase you indefinitely until you crossed a zone line, and if they belong to a species that could link they would bolster their numbers with any others they passed. Once their prey crossed the zone line they would then slowly wander back towards their spawn location, aggroing anyone else who had the misfortune of crossing their path. Popular EXP zones like the Jungles, Garlaige Citadel, and Crawler's Nest were easily paralyzed if one group pulled something high level they shouldn't or linked far too many mobs at once. Every group in the area would have to flee the zone and wait for an "all clear" from a dead person still inside once everything had left the area. Anyone zoning back in too soon would just pull the danger back to the zone line. Mercifully, Square finally tethered some mobs to despawn if pulled too far, and any mob that loses its aggro at a zone line despawns to eliminate the danger to bystanders.
* Many of the monsters in ''VideoGame/FinalFantasyXII'' seem to go to rather crazy lengths to catch the party. The ones that teleport, however, won't leave you alone until you leave the room, and a few monsters might just keep going.
* Most enemies in ''VideoGame/FinalFantasyXIV'' will give up chasing you after you run away for a while. This makes fair sense for things like animals, that were likely just guarding their territory, and are placated by leaving them alone. It makes less sense when you run right past a guard to an enemy military base, and he stops chasing you once you're 50 yards inside the base. Guess it's not their problem anymore.
** Played straight in dungeons, where enemies that spot you will hunt you down no matter how much you try to escape. This is actually beneficial in most instances, as now players can have a tank pull a huge group of mobs from a broad swath of the dungeon, group them up, and then take full advantage of AoE attacks to kill everything ''much'' faster than they would have killing things one at a time.
* In ''VideoGame/{{Gothic}} III'', you will often encounter packs of animals in the wilderness, from large birds to wolves, rhinos, and other beasts. Without exception, as soon as you attack a member of the pack, the entire group will go into berserk attack mode and chase you to the ends of the earth until either you or they are dead. One upside of this is that you can lead them into populated areas like cities, where the guards will assist you in taking them down.
* ''Videogame/GrimDawn:'' Nemesis monsters act like this. Unlike any other creature and boss, which will eventually head back to their spot once you've ran enough, Nemesis monsters will always know where you are once they've seen you and will ''never'' stop chasing you until you leave to a load-in area or use a riftgate to escape; they'll even chase you right into towns like this. Somewhat justified in their origins, as a Nemesis only spawns once its respective faction ''hates your guts'' because you've killed so many of them (even if it gets odd with a faction like the Beasts, which despite being barely sentient if at all still send a titanic half-wooden chupacabra after you), so like the name indicates they're out for retribution against you specifically, likely sent by their faction directly to hunt you down.
* Throughout the hovercraft chapter of ''VideoGame/HalfLife2'' the player is attacked repeated by Hunter-Choppers, but the fact that though the player gets a chance to shoot one down during the final confrontation at the dam the others just fly off for repairs, and the rebels that mount a machine gun on your hovercraft only mentioning a singular Hunter-Chopper, it's implied that it's the exact same one hounding you throughout the entire chapter and only getting temporarily driven off until you finally take it down for good at the dam.
* Illidan can very easily be this in ''VideoGame/HeroesOfTheStorm''. He moves fairly fast to begin with, and he can use his Sweeping Strike and Dive abilities to catch up to a fleeing hero. And in case that wasn't enough, he can also take The Hunt, so that if you do manage to escape his chase but then pass back into his team's line of sight, he can ''dive on you from across the map'', bellowing ''"You! Are not! PREPARED!"''
** Most of the time, people ''[[SubvertedTrope don't]]'' do this, at least in higher levels of play. Overextending while chasing a wounded enemy hero is a very good way to get isolated from your team and killed, meaning you feed the enemy team experience and cost your side a player while you wait to respawn, for no benefit.
* ''Franchise/JurassicPark'':
** In Telltale's ''Jurassic Park'' video game, the ''T. rex'' will constantly attack the protagonists throughout the game despite killing enough dinosaurs over the course of it that it REALLY has no reason to. The only thing that can distract it from chasing them is a Triceratops trying to kill it, and even then, it still takes a moment to divert its attention from the Triceratops to attack the humans.
** In the UsefulNotes/SegaGenesis ''Jurassic Park'' game, you can play as a Velociraptor whose sole motivation is to eat Dr. Grant. Each level the raptor is following his scent, going through the same levels you'd go through playing as Dr. Grant. She ''could'' eat the hundreds of dinosaurs and armed guards she kills trying to get to Grant, but no. Maybe the raptor has a thing against paleontologists (though there is mentioned in the narrative that the Raptor is trying to follow Grant to get off the island, rather than kill him).
* While Creator/PeterJackson's version of ''Film/KingKong2005'' uses this trope full-force in the movie as seen above, and you still get chased way too far by the V. rexes, the LicensedGame actually averts this as a specific game mechanic. A lot of time, you can divert the attention of a predator away from you by killing something smaller, causing the larger enemy to take the easier meal. There are even giant dragonflies and grubs you can stab with a spear, specifically for creating such distractions.
* The resident BossInMookClothing, The Eliminator, from ''Videogame/KingdomHeartsCoded''. In the game, is it the only enemy that not only teleports to keep you within its attack range, but after a certain level it will teleport ''between sector rooms''. This is rather unfortunate considering its power level.
** Another ''Franchise/KingdomHearts'' game takes this trope to its most ludicrous extreme: In ''VideoGame/{{Kingdom Hearts|I}}'', [[WesternAnimation/{{Tarzan}} Sabor]] the leopard repeatedly stalks and attacks a boy who can shoot fire and lightning from his body. This is more of a JustifiedTrope, though. The first time, she ambushes you, and she still [[NearVillainVictory very nearly wins]] -- only [[BigDamnHeroes the timely application of Tarzan]] saved Sora. The second fight it ''is'' at the campground, but it may have been there for other prey (like the monkeys... [[FridgeHorror you know, the ones that were just scattering the slides all over the place that you never see?]]) and goes after you. The third time (repeatable) [[InvertedTrope you land on her]]. In ''all'' of these, she [[KnowWhenToFoldEm is still well willing to leave after you take half her full HP out]]. Only the fourth time does she not leave, but even then she was more likely in the area to hunt [[EgomaniacHunter Clayton]].
* Several of the more mobile champions in ''VideoGame/LeagueOfLegends'' count as this, but Hecarim is the one of best. All of his abilities can be cast while moving, one greatly increases movement speed until a basic attack on an anemy, at which point he will launch both champions in his last move direction. His ultimate allows him to dravel through walls, trees, et cetera. You will never escape a Hecarim unless your team helps you. Warwick can sense low-health enemies ''anywhere'' on the map and gains a large movement speed boost while tracking them. And his main combat gimmick is being more lethal to enemies already injured, as well. Knowing when it is and isn't safe to recall to safety is a skill quickly acquired playing ''League''.
* ''Franchise/TheLegendOfZelda'':
** {{Averted|Trope}} in ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' by non-monstrous predatory animals such as wolves and bears; while they'll attack Link opportunistically if he stumbles upon them, they'll immediately flee upon being wounded or having a member of their group killed. In the case of the pack hunters, they'll also generally run away if Link happens upon any that are alone.
** The [[ThreateningShark Gyorgs]] around Tingle Island in ''VideoGame/TheLegendOfZeldaTheWindWaker'' will follow you until you either reach land or kill them.
* ''[[VideoGame/LetsGoJungle Let's Go Jungle: Lost on the Island of Spice]]'' has that ''[[GiantSpider oversized tarantula]]''. It chases you as the first boss (but your characters escape it), then re-appears in the third level as a MiniBoss (and your characters knock it off a cliff), and just at the end, it attacks you ''again''. You finally put it to an end by dropping it on deadly radioactive waste, which causes the [[NiceJobBreakingItHero plants nearby to mutate into a]] ManEatingPlant.
* ''VideoGame/{{Limbo}}'' has the game's only boss, a giant spider. [[spoiler:It has ''only one leg'' the last time it shows up, but despite that it still tries to kill you.]]
* ''VideoGame/TheLongDark'' features a game mode where an [[NighInvulnerability unkillable]] [[BearsAreBadNews old bear]] attacks you at the very start of the game and continually chases you throughout the map to try and kill you anytime you're outside. Shooting the bear with a flaregun will cause it to momentarily retreat (while a flare to the face is invariably fatal for other animals including normal bears). Once you get to the hunter's cabin in Mystery Lake, you can find a hunting rifle capable of hurting it and return the favour.
* Impact Man from ''VideoGame/MegaMan11'' doesn't even wait for Mega Man to enter his boss room, instead breaking into his [[CombiningMecha component pieces]] and going out to harass him in the level itself throughout several rooms.
* ZigZaggingTrope in ''VideoGame/Metro2033''. The [[NuclearMutant Moscow mutants]] will go to great lengths for a meal, even going so far as to attack armored humans with automatic weapons. Similarly, they are not deterred by gunfire, bright light, or the smell of their own dead, as most normal animals. On the other hand, shooting them will usually cause them to back off momentarily, they do eventually flee if enough of their pack is killed, they are frightened of the [[EldritchAbomination anomalies and ghosts that infest the haunted tunnels]], and they will also avoid large fires (though they will brave them if there is no other option). Totally averted with some other mutants -- Librarians, the possibly-once-human, possibly sentient mutants that infest the Lenin Library and the Military Archives beneath it are simply territorial, and will even back down if you look them right in the eye (in the novel, one even tells Artyom to "go away" in Russian), and the Biomass under [=D6=] ignores you until you start actively trying to kill it. The Demons, winged mutations of the tigers in the Moscow Zoo, will not try to follow you inside, though they will opportunistically try to snatch you if you spend too long outside or near windows. Overall, the unusual persistence of the Moscow predators is justified by the scarcity of food in the Metro -- they are just as starved as the humans they feed on, and they really can't afford to ignore such a tempting target as an adult human (or better yet, woman and children he's guarding) unless they have no other option.
** ''[[VideoGame/MetroLastLight Last Light]]'' expands a bit on the situation, giving some of the mutants additional motivations for their behaviour and pushing the game closer to a full aversion of the trope. Watchmen are shown to possess a limited capacity for restraint and rational thought, being content to leave Artyom alone so long as they're not starving or if he doesn't provoke them. They are also more apt to break off an attack if they lose too many of their own, and the [[spoiler:Baby Dark One]] points out that they fear what they don't understand when lending Artyom his psychic facilities to seek them out in cover with. On the other hand, Demons and the new Bear boss-mutant are both shown at various points in the game to be simply protecting their young, and the same is implied for the Nosalis Rhino (a Nosalis brood mother who watches over a large pack of them). The aquatic Shrimp are docile unless bothered by disturbances in the water, which a group of Reds promptly create while carelessly boating through Shrimp-infested tunnels.
* ''VideoGame/MetroidFusion'' has the SA-X, Samus' Power Suit taken over by an X-parasite which chases you through the entire game with no way to stop it. (The SA-X is fairly easy to fool, though, not being able to find Samus should she slip out of immediate view.) On the other hand, since Metroids ''eat'' X-parasites, Samus effectively plays the role of Super Persistent Predator in the game itself. Although technically Samus is [[BerserkButton also a Metroid in this game]]. And the SA-X has some of Samus's instincts, such as [[OhCrap eliminating all Metroids]].
* The player in ''VideoGame/{{Miasmata}}'' is being stalked by a deadly creature that will follow him around the entire island and is liable to attack at any hour of day or night.
* In the Chimera Laboratory in ''VideoGame/{{Mother 3}}'', the Ultimate Chimera is chasing you around. It can't be hurt, and if you touch it you'll get an instant game over without even entering battle. What's more, [[spoiler:in New Pork City later on, you find it an inch from your face, SITTING ON A TOILET in a stall you just opened in the bathroom dungeon]].
* ''VideoGame/MonsterHunter'':
** The series at large inverts this. Most large monsters tend to flee from the player after exhausting themselves or sustaining large amounts of damage, and usually have to be chased in order to be taken down. In other words, the ''player'' is an example. Also, when hungry, monsters will leave to find easier game, generally going for the easiest to kill herbivores available or even scavenging, than the heavily armed human in front of them. They will also revert to a neutral state if you leave an area to heal up. All in all, monsters really want nothing to do with the hunter at all and will make any effort to scare him/her away or flee themselves. While this can seem [[HumansAreTheRealMonsters quite sad, really]], other material makes it clear large monsters often run because the hunter's a tough nut to crack. Plenty of quest descriptions mention stealing livestock or attacking exposed caravans, and ''VideoGame/MonsterHunterStories'' in particular shows these incidents can very easily have a body count.
--->'''WebVideo/Max0r:''' After a long and arduous battle, you (the monster) run away as far as you can. But, every time you turn around, he's still there. And even worse, '''IT'S WEARING YOUR SKIN'''.
** Averted to another extent during Rampage Defence quests in ''VideoGame/MonsterHunterRise''. Most of the waves of large monsters are merely following the tide and running into a sufficiently dense defensive line will make them go ScrewThisImOuttaHere with even less injury than in the field. Only the "Apex" monster directing the horde will stand and fight, and they're sufficiently agitated to fight to the death.
** A notable exception to this is the [[TheDreaded Deviljho]] from ''VideoGame/MonsterHunter3Tri'' and onward; it is an invasive Apex Predator that will actively chase prey down to sate its never-ending hunger, no matter where it goes. This is because it has a HyperActiveMetabolism, which makes it burn energy really quickly, and allows it to invade any ecosystem. In ''VideoGame/MonsterHunterWorld'', the Savage Deviljho variant will even [[SlidingScaleOfGameplayAndStoryIntegration refuse to ever run from battle]] no matter how much damage is done to it, and will chase the player to the ends of the earth if they try to run (most monsters will give up after a certain distance).
* The polar bears in ''VideoGame/NeverAlone''. {{Justified|Trope}} given that they're [[BearsAreBadNews polar bears]], which really will stalk humans for miles due to how scarce food is in the arctic.
* There was a [[GoodBadBugs glitch]] in ''VideoGame/TheOregonTrail III'' that sometimes made wild animals act like this. If you went out hunting and fled from an angry bear, the bear would appear right in your face the next time you went hunting, ready to maul your party members. This bear would follow your wagon for ''[[AutomatonHorses thousands of miles]]'' until you managed to kill it.
* ''VideoGame/{{Pikmin}}'': The Spotty Bulbears are already DemonicSpiders on their own, but ''VideoGame/Pikmin2'' upgrades them in numerous ways, one of which is that, while every other enemy in the game (except the similarly persistent but less threatening Gatling Groinks) has a set radius they'll stay in before giving up chasing you, they have no such limit and will follow you to the ends of the earth until one of you is dead. Even then, the Bulbear's corpse will have to be harvested, or it will [[HealingFactor come back to life]].
* In ''VideoGame/PlanetExplorers'', some aggressive animals will chase the player for hours, even when mortally wounded.
* ''Franchise/{{Pokemon}}'':
** Krookodile, a crook [[NeverSmileAtACrocodile crocodilian]] that's said to never allow its prey to escape. Oddly, it doesn't learn the move Pursuit through normal means, though it's still better than [[ThreateningShark Garchomp]], who's said to be similarly persistent but doesn't learn the move at all.
** While never specified to be a predator, Primeape fits the persistent part because it ''never'' gives up chasing whoever angers it till it has beaten them up. This happens a lot, because the Pokémon has such a extreme HairTriggerTemper it's near constantly in a UnstoppableRage. Possibly averted in Sun and Moon, where a Pokédex entry notes that it has been known to become so angry that it ''dies''.
** In gameplay, running away from a wild Pokemon is determined primarily by the difference in speed between the combatants. Fast wild Pokemon will simply not let you escape from battle. Some of them even use a move (Mean Look) or an inherent Ability (Magnet Pull, Arena Trap) to lock you into the battle until either your 'Mon has fainted, or they have been knocked out or caught.
* ''VideoGame/QuestForGloryIII'' has Dinosaurs. Throughout the series it's possible to escape monsters simply by running for it. Not Dinosaurs. Unless you cheat by jacking the game speed up they will continue following you across the Savannah no matter ''how'' far you run.
* The shark in ''VideoGame/{{Raft}}'' will hunt you and your vessel endlessly. You can distract it with bait, but once the bait is gone, it will come back for you. You can kill it (and butcher it for delicious shark steaks), but an identical shark will show up a day or two later to resume the hunt. Even repeatedly stabbing it with a spear or arrows doesn't convince it to back off for a moment.
* In ''VideoGame/RavenswordShadowlands'', each and every enemy, once they spot you, will ''not'' give up trying to reach and kill you until either you or them are dead, or until you completely leave the worldspace that they (or the dungeon they live in) are situated. And since you ''cannot'' use Fast Travel while someone is attacking you, it's entirely possible to get yourself stuck inside a dungeon with aggro'ed enemies waiting outside and with no ability to fight back. Add in the fact that the enemies are capable of [[CycleOfHurting stun-locking]] you if enough of them are beating you at the same time, and the fact that the game has limited saves, and you have a recipe for potentially making the game {{Unwinnable}}.
* In ''VideoGame/RedDeadRedemption'', cougars, wolves, and bears will chase John for ridiculous distances in which most real life predators would have long since given up and gone after easier prey. Even shooting them doesn't mean they will stop. Also, coyotes, wolves and even bobcats will attack you, when all of these animals mostly avoid humans in real life.
* Nemesis from ''VideoGame/ResidentEvil3Nemesis'' deserves special mention as he can follow you even to other rooms. Normally all one had to do to run away from an enemy is go into another room, but you have to run away quite a bit from Nemesis before he finally gives up. It was explicitly engineered and programmed to hunt down S.T.A.R.S. members, which Jill is. That's all it was made to do.
** The T-00 (Mr. X) in ''VideoGame/ResidentEvil2'' was the first draft for Nemesis, as he would follow either Leon or Claire in their B scenario throughout the entire game, but only in scripted encounters. And it's only Leon or Claire, as while he's ostensibly meant to hunt down the G-virus, in a couple of spots, he will ignore the character who has a sample of the G-virus on them (either Ada or Sherry) to chase Leon or Claire in the elevator security room. [[VideoGame/ResidentEvil2Remake The remake]], on the other hand, turns off the scripted encounters, and turns him into a relentless pursuer who '''will not''' stop until every living person in Raccoon City is dead.
** ''VideoGame/{{Resident Evil Village}}'' continues the trend with Lady Dimitrescu, who will pursue Ethan Winters throughout her castle until her boss battle.
* ''VideoGame/SpellingJungle'': Tigers (in ''Spelling Jungle'') and wolves (in ''Spelling Blizzard'') will chase after Wali, and won't stop unless he crosses a type of terrain that they can't. The Abominable Snowman is the same way in the second game, with the added feature of not being halted by snow like the wolves.
* ''VideoGame/StringTyrant'' Has an enemy called The Stranger, which actively looks for Mary instead of patrolling, and respawns stronger upon defeat. It even sort of resembles Mr. X.
* Invoked for horror in ''Videogame/SunlessSea'': Most zee-monsters behave relatively normally in this regard, and will stop chasing you once it's clear you've gotten away. The Constant Companion, however, doesn't. If you dare dive beneath the surface [[SanityMeter with your Terror above 70]], this [[GiantSpider gigantic arachnid monstrosity]] will pop itself out of the zeefloor and will ''not stop hunting you'', even if it means having to literally chase you through the entire map. At least it can't float, so resurfacing will keep you safe, but it will gladly wait for you to come back with high Terror to begin its chase again.
* Hilariously, the ''[[SelfImposedChallenge Green Demon Challenge]]'' of ''VideoGame/SuperMario64'' turns a 1-Up Mushroom into this. The challenge involves triggering said mushroom that homes in on Mario and then avoiding it long enough to collect the red coins. Every step of the way that 1-Up will be [[NightmareFuel staring doll-eyed at the screen]] mercilessly chasing Mario throughout the level and it absolutely will not stop, EVER, until you get a 1up.
* Coda the Pelican from ''VideoGame/TadpoleTreble'' is described as this in regards to Baton the Tadpole. The Bestiary even specifically compares him to Wile E Coyote. It's downplayed, in that Coda only really goes after Baton whenever she's in his territory. [[EverythingTryingToKillYou He probably had to get in line with all the other predators after he missed his first chance.]]
* Part of what gives Hammer Haunts their {{Demonic Spider|s}} status in ''VideoGame/{{Thief}}'' is that, while normal guards will stop chasing you after a while and run away if their health gets too low, Hammer Haunts do neither. If they spot you, they will chase you to the ends of the earth and only death (or climbing up somewhere they can't reach) will stop them.
* Justified in ''VideoGame/VampireTheMasqueradeBloodlines'' with the werewolves. [[spoiler:Nines]] specifically decides to hide out in their territory because they're known to hate vampires, and no one will look for him there. Even then, they leave him alone, until [[spoiler:a different vampire sets fire to their territory]] -- then two of them go looking for retribution.
* ''VideoGame/TheWolfAndTheWaves'': If a zombie spots you, it will chase you across the island until it dies, even if you move far beyond its field of vision.
* Usually, monsters in ''VideoGame/WorldOfWarcraft'' are leashed, meaning they'll reset to previous positions if you outrun them for long enough. However, for a while after they were put into the game, there was a bug with the giant spiders of [[NamesToRunAwayFromReallyFast Deadwind Pass]] where, once aggro'd, they would never reset. They would follow you across multiple zones, through aggro reset mechanics, ''even through death.'' Even if you somehow managed to get on a flight path to get away, if you ever came back... it would be waiting.

* In ''Film/{{Godzilla 2014}}'', Godzilla tracks the [=MUTOs=] from one side of the Pacific to the other. {{Justified|Trope}} [[spoiler:considering Godzilla considers the entire Earth its territory and the [=MUTOs=] are an active threat to the biosphere, as well as the fact they're explicitly parasitoids which utilize his species as a host, so he has a ''personal'' reason to prevent them from breeding (outside of fighting each other just being what kaiju do naturally)]].

''WesternAnimation/IceAgeDawnOfTheDinosaurs''

** we have [[spoiler:Rudy (though his case may be justified, seeing as he's out for vengeance against a rival among the protagonists as well as just a meal)]]
** And a pack of hungry pterosaurs.

* Not exactly a predator, but Scrat, the [[CartoonCreature prehistoric squirrel]] in the ''WesternAnimation/IceAge'' series is pretty persistent about getting That One Nut; his attempts, and [[FailureIsTheOnlyOption subsequent]] [[ButtMonkey failures]], to eat it is a RunningGag. In the third film, we have [[spoiler:Rudy (though his case may be justified, seeing as he's out for vengeance against a rival among the protagonists as well as just a meal)]] And a pack of hungry pterosaurs.

* In ''LightNovel/SoImASpiderSoWhat'' the Anogratch are known as the "Revenge Monkeys" because if you kill even one member of their troops, its thousands of kin will not stop until they have killed you. As Kumoko found, they will literally ZergRush the attacker until every last member of the troop has been killed.
