10. Boomer - Left 4 Dead (2008)
Boomers are nausea incarnate. One of several Special Infected in the Left 4 Dead universe, these hulking, boil-infested undead are usually detectable from afar thanks to their constant groans of bile-induced queasiness. But notice them too late, and you’ll be showered in a green, oozy vomit right before one of your teammates bursts them right open with a shotgun.
9. The Master - Fallout (1997)
One of the primary antagonists of the original Fallout, The Master looks more like roadkill than the creator and leader of a race of super mutants. By the time the Vault Dweller encounters him, he’s a biomechanical nightmare: a mass of stretched flesh fused with the electronic equipment of his gore-filled lair, with eyeballs where they shouldn’t be and ribbed tubes jutting out of his sinewy, mutated remains. Body horror at its finest.
8. Asphyxia - Silent Hill: Homecoming (2008)
The Silent Hill universe is full of disturbing creatures borne out of the minds of its many troubled protagonists. While most of them are downright horrifying with the right context, Asphyxia needs no explanation to revolt onlookers. From the moment she slithers out of the fleshy hole in the Otherworld penitentiary's wall, this multi-limbed, human centipede-esque monstrosity has earned her place as one of Silent Hill’s grossest enemies.
7. Bloater - The Last of Us (2013)
Zombies are gross, but there’s something particularly nasty about the cordycep-infected creatures of The Last of Us, with their molded skin and fungus-sprouted heads. Bloaters are the final stage of this parasitic evolution, a scarred giant covered in blooming growths. One of its most annoying and disgusting attacks: ripping sacks of toxins off of itself and bombing the player with them, covering the arena in a cloud of noxious spores.
6. Infested Corpse - Dark Souls 3 (2016)
The Reanimated Corpses that wander the Cathedral of the Deep’s graveyard are like dumber, weaker Hollows, making them prime targets for easy grinding early in the game. But among the hordes of pale undead are the Infested Corpses, which appear to be normal, zombie-like creatures until, from their chests, bursts a second, sentient mass of writhing maggots. The growth has a mind of its own, creeping forward with its worm-covered arms and swiping (sometimes spewing) hundreds of the squirming larvae all over the player.
5. Clotho - God of War II (2007)
The towering, worm-like Clotho — a sickly, multi-armed mass of pallid skin, dotted with boils and bone-like growths — is a sight to behold. From the waist up (her first waist), she doesn’t seem like much: an immobile, greying goddess that can only swing her spindly, tumor-speckled arms at Kratos before he impales her head with a suspended blade. But from top to bottom, this humanoid silkworm is an overwhelming monstrosity.
4. William Birkin (5th Form) - Resident Evil 2 (1998)
The Umbrella Corporation has produced its share of horrors, but few come close to the repulsive blob of gore that is William Birkin’s fifth tyrant form. After injecting himself with the G-virus, this scrawny scientist goes from a hulking, bipedal bioweapon (iconic eyeball sprouting from his enlarged shoulder), across several stages of monstrosity before finally mutating into what we see here: a slimy, betentacled pile of veiny flesh and bone, all centered around a sarlacc-like cavity framed by rows of compact tusks and eyes.
3. Guardian - Dead Space (2008)
Dead Space is full of disgusting necromorphs of all shapes and sizes, but the Guardians are one of the most repulsive varieties. These immobile monstrosities look like a tangle of entrails smeared on a wall. With their extremities atrophied into nothing and a flurry of tentacle-like appendages bursting from their enlarged thorax, the only thing recognizably human left is their face, stretched in agony above a gaping chest cavity. They also expel a mutated, embryo-like creatures from a bloody orifice (one of them) as self-defense. It’s hard to believe it can get grosser than these guys.
2. Lepotica - Resident Evil 6 (2012)
What sets the slimy, split-faced Lepotica apart from the rest of Resident Evil’s repulsive horrors is the cluster of gaping sacs that make up its bloated torso. This thing is a trypophobe’s worst nightmare. Its oversized pores spew toxic gases that kill and reanimate anyone nearby, opening and closing in rhythmic bursts in the process. As if that wasn’t disgusting enough, it can also open its face up like the dog from The Thing, turning its head into a flower of gore as it attempts to attack the player.
1. Brain of Mensis - Bloodborne (2015)
Next to the rest of the enemies on this list, The Brain of Mensis poses the smallest threat, but we’d be lying to ourselves if we said it wasn’t the most disgusting thing we’ve ever encountered in a game. Like an enlarged head of a Winter Lantern, the Brain of Mensis (or Mother Brain) is a quaking mass of decaying tissue, bulging eyeballs of all sizes lodged on every side of its shapeless mass, wiry black hairs, crooked tendrils, and other miscellaneous gore sprouting out every which way. The fibrous stem that hangs off one end is covered in sac-like growths and, in the dark stillness of the void, you can hear its slimy pulsing. Bloodborne is brimming with grotesque sights (and sounds), but when it comes to the most disgusting creature in the game (and in general), the Mother Brain takes the very bloody cake.Which video game enemies gross you out the most?
