In pretty much every case, this is Nightmare Fuel owing to our Primal Fear of Orifice Invasion. See also Personal Space Invader. A creature that does this is frequently the larval form of a Xenomorph Xerox.
- The mind-control starfish of Starro the Conqueror in The DCU.
- In the Slash Fic parody ALIEN!!!, the facehugger is a lesbian cyborg who wraps her legs around the heroine's face.
- The Trope Namer and Trope Maker (if not Ur-Example) is the crab-like impregnator from Alien. Many later examples are homages.
- The dreamcrabs in the Doctor Who episode "Last Christmas" attach themselves to their victims' faces and slowly eat their brains, while trapping them in dreams. One of the crew even lampshades the situation as being right out of Alien, which is justified with The Reveal that one of them was actually watching the movie when the dreamcrabs put them into the dream.
The Doctor: There's a horror movie called Alien? That's really offensive. No wonder everyone keeps invading you.
- The giant spiders contained in the Box of Gavrok in Buffy the Vampire Slayer attach themselves to people's faces before killing them.
- The Mandalorian. Played for laughs when the Child is tucking into a bowl of chowder whereupon a small squid-like creature bursts from the bowl and latches onto his face.
Mando: (sternly) Don't play with your food. (Pokes the squid with his knife, and the squid falls back into the bowl)
- The Face Sucker in Munchkin.
- Warhammer 40,000:
- Facebiter squigs bite... faces. The orks naturally find this hilarious, and often get in contests to see which will bite the other's face off first. The actual Xenomorph stand-ins use an ovipositor to perform the Orifice Invasion instead.
- The Tyranids have a variant species of Ripper called a Cortex Leech. They leap onto a person's face then use a variety of pointed tendrils to penetrate the mouths, eyes, nose, ears, or any other available orifice and drive them into the brain, where they can then hijack the motor functions and turn them into drooling thralls to the Hive Mind.
- The Catachan Face Eater. On a planet with the ultimate reputation for Everything Trying to Kill You, this creature is probably the most feared predator.
- Krana and Krana-Kal of BIONICLE.
- The Toa Inika possessed a benevolent version of these - unlike normal Toa, their Kanohi masks were organic, living creatures. Unlike the very similar Krana, however, their only interest was helping the Toa, mainly by teaching them how to properly use their powers. Although, their primary method of doing so was giving them nasty headaches whenever they did something wrong...
- The Skull Spiders from the 2015 reboot.
- Metroids, although more often than not they latch onto the whole head.
- Headcrabs from the Half-Life saga.
- Brainsuckers from X-COM: Apocalypse, which are used as ammunition by certain aliens in addition to appearing on their own. Replacing a person's brain is their entire purpose; They don't even have a digestive system.
- The Protozoid Slimers from Duke Nukem 3D.
- The Lifters and Diamond Claws from the Descent series behave similarly. While most of the other robots shoot at you, these enemies ram into your ship and inflict damage with their reinforced claws.
- The E-Bandits use a similar point-blank attack, only they drain your ship's energy instead of your shields.
- Psi-Ops: The Mindgate Conspiracy: The Aura Beasts come of nowhere and wrap around Nick's face. Oh, and the only way to see them coming is using the psi draining Aura Vision.
- Space Quest
- In Space Quest III: The Pirates of Pestulon, at Fester Blatz's World O' Wonders on Phleebhut, the postcard for Achoron shows a face hugger hugging somebody's face.
- In Space Quest V: The Next Mutation, Spike, the acid-squirting face hugger, later dubbed Spikette, spawns lots of little face huggers. The manual shows the design team being inspired by an Alien face hugger model.
- In Space Quest VI: Roger Wilco in The Spinal Frontier, when examining the ship in shuttle bay, the narrator claims the ship is "probably carrying a half-dozen miniature face-hugging saliva-dripping face-eating exo-skeletal alien piranha things."
- In Campus Safari, Chrome's miniwhip Aurla does a good impression of one. (Played for laughs)
- Cross Time Cafe: Sam Starfall pulls one of these off in an early strip. Hortmage finds it irritating and, maybe, disgusting.
- Edward's monster in Monster Pulse. It helps that it's actually his face.
- In Zero Percent Discount, a Banana Peel turns into a facehugger.
- In Savestate, Rick is subjected to this by Ness, much to his irritation and, apparently, Nicole's amusement.
