* The Ghost in ''VideoGame/{{Spelunky}}'' is intangible to walls and cannot be deterred from pursuit, much less killed (except via a certain glitch in the HD version). It spawns under one of three circumstances: [[StalkedByTheBell when the timer on a level reaches 2:30]], upon picking up a Crystal Skull in the Restless Dead Levels, which will summon a second ghost if the aforementioned time limit has already
been reached, or if the player destroys three or more of Kali's Altars, in which case it will pursue the player from the beginning of every level for the rest of the game, in addition to them being slowed down with the punishment ball & chain.

It spawns under one of three circumstances: [[StalkedByTheBell when the timer on a level reaches 2:30]], upon picking up a Crystal Skull in the Restless Dead Levels, where a second ghost will spawn alongside it if the aforementioned time limit is reached, or if the player destroys three or more of Kali's Altars, in which case it will pursue the player from the beginning of every level for the rest of the game, in addition to them being slowed down with the punishment ball & chain.

* The ''VideoGame/{{Doom}}'' GameMod ''VideoGame/MyHouse'' has two; the functionally invincible and intangible Shadow Archvile, which the player must flee from in the path to the GoldenEnding, and the Skinstealer, who guards the [[MinusWorld Backrooms]] and will pursue you until you either die or find the escape route back to the main level.

* In ''VideoGame/MediEvil,'' the overwhelming majority of the monsters can be defeated no matter how tough they seem at first, befitting the horror-comedy atmosphere. However, in Scarecrow Fields, there's ''something'' living in the cornfield that cannot be fought, cannot be killed and ''[[NothingIsScarier cannot even be seen]].'' If you stray into the cornfield and don't leave immediately, you'll be rewarded with [[HellIsThatNoise an ominous hissing noise]] as something large rushes through the corn towards you, and then you will instantly lose a life. That's it.

** The SA-X of ''VideoGame/MetroidFusion'' is a copy of Samus at her full strength, and as such can kill her in a few hits, freeze her in place and generally forces the player to run when its [[HellIsThatNoise telltale footsteps show up]].

* ''Series/TheHauntingOfHillHouse'' ultimately reveals that the [[GeniusLoci eponymous house]] is one of these; not only is [[MindRape its power]] just about impossible to resist, but the building is seemingly indestructible. Trying to burn the place down only results in the fire ''instantly extinguishing itself,'' followed by swift retaliation from the ghosts it commands. [[spoiler: Only the intervention of Nell's ghost saves her siblings from [[EldritchLocation the Red Room]], and even then, she can't do much more than keep them safe until the family's out of the building.]] In the end, the only thing you can do is remain as far away from it as possible, and ''never'' visit after nightfall.

* ''Manga/JoJosBizarreAdventureGoldenWind'': Carne's Stand, Notorious B.I.G, is unique in many respects: it only activates [[DeathActivatedSuperpower after Carne's death]] and thus, the standard strategy of "knocking out/killing the Stand user to stop the Stand" is useless. It's a BlobMonster that consumes everything in its path, is nigh-indestructible -- having pieces of it chopped off will just make the pieces sentient -- and it will chase after any sufficiently speedy thing nearby, and it can move really fast. Its only weakness is that it only acts in primal instinct, so it can be fooled in various ways; the protagonists only get rid of it after it hijacks the plane they're flying in (by partly consuming it) and they escape in midair, while the plane's failing engine causes it to fall towards the ocean. Even then, it's still alive, thoroughly confused with the ever-moving ocean currents (which trigger its instinct); it's said that the ocean it fell in becomes a scary place, with multiple ship sinking incidents caused by the still-living Stand.

* Generally speaking, the only way for a DM to really accomplish this in a TTRPG is to not give their monster any solid HP total until the final encounter where it's meant to be killed, and even then that may not be a fullproof solution as most [=TTRPGs=] give the player other means of dealing with them, such as in ''Tabletop/DungeonsAndDragons'' having a myriad of spells such as teleporting, putting to sleep, paralyzing, and other such abilities to make the threat it presents moot. If a DM really wants them to be invincible, they would also need to imploy ContractualBossImmunity, and even then they will need to be careful to not make it feel like RailRoading or potentially [[TotalPartyKill killing the entire party]].

* In ''[[Literature/ThePrecipice The Precipice]]'' Stitchskin quickly becomes this in Grace's brief encounter with the shapeshifter. It dosen't help that she is a very green Super with a power not particularly well suited to direct confrontation and no weapons prepared that can hurt Stichskin through his shape-swapping ability.

* The Xenomorph in ''VideoGame/AlienIsolation.'' It's almost immune to all weapons, trying to tackle it up close is suicide, and the only item that's of any use against it is a flamethrower -- and that's only because it's afraid of fire... at least until it begins to learn how to react to it. More often than not, the safest option is to hide in a locker or run for your life in as quiet a manner as possible, ideally while it's distracted by hunting down other human targets.

* In ''VideoGame/AloneInTheDark1992'', disturbing any of the ghosts in Derceto Manor results in them shapeshifting into an invincible spinning conglomeration of translucent pastel-colored orbs that relentlessly pursues the PlayerCharacter, even through walls, and inflicts a OneHitKill upon contact. Your only option is to avoid angering them in the first place.

** ''VideoGame/ResidentEvil6'' has the Ustanak, the C-Virus analogue to Mr. X and Nemesis, who relentlessly hunts Jake and Sherry throughout their campaign, and nearly all obstacles they throw in its way, such as a giant mining drill, an electrical pylon, and a smelting pool, are at best brief hindrances to its pursuit. It is finally KilledOffForReal when the duo shoot its exposed heart with an [[HandCannon Elephant Killer magnum]].

* ''Franchise/SilentHill'' series:

* Pyramid Head from ''VideoGame/SilentHill2'' can be slowed down your attacks, but not killed. The first encounter simply ends after a fixed amount of time, after which he walks away (and will kill you if you follow after). This is played with in the penultimate boss fight, where the [[DualBoss two Pyramid Heads]] have hit points you deplete like a conventional enemies, but while depleting them ends the fight, it doesn't kill them. [[spoiler:Instead it triggers a cutscene where James realizes they are [[EnemyWithout manifestations of his own guilt]], after which they both kill themselves.]]
* ''VideoGame/SilentHill4'' has the Victims, who phase through walls while pursuing Henry, and get back up within a second or two of being knocked down. The only way to keep one down indefinitely is with Swords of Obedience, which are extremely limited in supply. The game's second act has each area haunted by its own "Super" Victim, which are much more relentless than the normal Victims. The BigBad, Walter Sullivan, also chases Henry and Eileen throughout the second act, and can't be fought until the finale.
* ''VideoGame/SilentHillShatteredMemories'' has the Raw Shocks, the game's only proper enemy type which appears in the franchise's characteristic Otherworld, who can't be fought, turning every Otherworld sequence into a hectic chase with the monsters. This was presumably done in direct response to the criticisms of the combat-heavy ''VideoGame/SilentHillHomecoming''.
* ''VideoGame/SilentHillDownpour'' has a hammer-wielding GasmaskLongcoat stalker [[ExactlyWhatItSaysOnTheTin officially called the Bogeyman]], who serves as Murphy Pendleton's personal tormentor in the same manner as Pyramid Head. During the final battle, [[AndThenJohnWasAZombie Murphy himself takes the form of the Bogeyman]], at least from deuteragonist Anne-Marie Cunningham's point of view.

* ''VideoGame/SirYouAreBeingHunted'' has The Landowner, the unkillable final boss of the game. Despite being as such, he is able to spawn incredibly early into a run and proceeds to roam the map indefinitely. Should he become aware of the player however, he gains permanent vision of him making hiding impossible and will never stop stalking him. The only way to lose him is to head to a different island.

* In ''Bug Hunt''(the Macintosh World Builder game), the XenomorphXerox [[InstantWinCondition can be neutralized in its larval form if you manage to assemble the Flamethrower fast enough]], but once it metamorphoses into an adult, it becomes NighInvulnerable, whereupon your only recourse is to run from it and activate the space station's SelfDestructMechanism, or lure it onto the emergency shuttle, rig it to explode, and remotely launch it.
