History Main / InvisibleMonsters

** The original game has Larval Stalkers, which can't actually hurt you, and later, Invisible Gray Children.

* The Krafayis from DrWho episode, ''Vincent and the Doctor.''

See also InvisibleMan.

In other media, especially Television, an Invisible Monster is used to save budgets for more outlandish monsters. Often, they are accompanied by creepy noises or music that alerts the Audience to their presence. Done well they can be [[{{Narm}} laughable]], done right, [[NightmareFuel terrifying]].

You can't [[supersecretspoiler:see them]], but they can probably hurt you.

* ''TheLegendOfZelda: Ocarina of Time'' has the [[WallMaster invisible hand monsters]].
* ''Zelda II'' has invisible ghosts in the abandoned town.
** Before you have a source of light, the caves are full of invisible enemies. Passing through this is neccessary to continue.
* ''TheLegendOfZelda: Majora's Mask'' had invisible Skulltulas attacking you potentially before you got the Lens of Truth.
** In ''Ocarina of Time'' and ''Majora's Mask'', Tatl/Navi can see and target them, though.
* ''TheLegendOfZelda: Twilight Princess'' has those [[GoddamnedBats goddamned]] [[spoiler:zombie rats]]. [[NightmareFuel Oh, jeepers]]!
* ''TheLegendOfZelda: Link's Awakening'' has a group of invisible enemies directly outside the room with the item that makes them visible. Said item is intended for a few other (non-battle) purposes.
* ''TheLegendOfZelda: Phantom Hourglass'' has a boss like this -- but you can see yourself through the monster's perspective and judge its rough location.

** The Omega Pirate makes itself invisible when it's recharging. You need to use the X-Ray visor to see it. But first, have some Beam Troopers of various sorts!

* The assassins in ''HalfLife'' are invisible if you play on the Hard [[DifficultyLevels Difficulty Level]].

* The Spy in ''TeamFortress 2''. Cannot attack while invisible, though.

* ''KingdomGame/KingdomHearts'' gives us the Stealth Sneak, first as a BossBattle, then reappearing later on in the Hades Cup. The icing on the cake is one of the latter seeds, consisting of not one but ''two'' Stealth Sneaks to carve up. Mind you, locking onto and hitting one is not affected by whether they are visible or not. They can be detected by sight alone if you look very carefully. Their camouflage produces a "heat ripple" effect, though this is easier to see during the boss fight than during the seed match.

* [[HarryPotter Dementors]] can't be seen by {{Muggle}}s.

* Also in ''{{Tron}} 2.0'' are the Datawraiths who, while not technically invisible, tend to warp in and out of the level.

* In ''Metroid Prime'' you face off against Chozo Ghosts, which are invisible when not attacking.

* The turn-based RPG ''Gorky 17/Odium'' features, near the end of the game, a group of invisible mmonsters which are visible only when they move. You have to remember where they stopped so that you can shoot them (explosive weapons come in handy, as they cover a wide radius).

* ''Game/KingdomHearts'' gives us the Stealth Sneak, first as a BossBattle, then reappearing later on in the Hades Cup. The icing on the cake is one of the latter seeds, consisting of not one but ''two'' Stealth Sneaks to carve up.

* [[TheHeartless Hollows]] in ''{{Bleach}}'' could not be seen by anyone who could not [[ISeeDeadPeople see dead people.]] This lead to the first few episodes having these...things chasing people that nobody could see. Only the footprints and scenery destruction following them. ** Even those who can see dead people have trouble seeing them; you need to have a lot of dead person energy built up. Even Ichigo couldn't see them until the start of the series, and he had trouble telling the dead from the living when he was younger.

*The Gnoolies, in {{RoaldDahl}}'s ''Charlie and the Great Glass Elevator''.
