Biggest Xenomorph Hives and Infestations, Ranked
A Xenomorph hive is more than resin on the walls. It is the colony's nursery, staging ground, and home base between hunts. Queens and their brood prefer warm, dry spaces, and an unchecked infestation can swallow a ship, a station, or an entire world. This ranking covers the largest notable hives and outbreaks across Alien movies, games, and comics, judged by geographic spread, victim count, and the tier of Queen involved. For a chronological look at outbreaks on humanity's homeworld, see Xenomorphs on Earth.
What Counts As A Major Infestation?
Not every cluster of Xenomorphs qualifies for this list. A lone drone stalking corridors, like the Dragon Runner on Fury 161, still left behind a small functional nest, but the entries here are defined by scale: hundreds or thousands of hosts, multi-level resin structures, and often a reigning Queen, Empress, or Queen Mother. Smaller nests without royal leadership are included when the victim count or geographic spread still made the outbreak hard to contain.
10. USM Auriga Hive
The USM Auriga from Alien: Resurrection was one of the largest vessels in the franchise to fall to Xenomorphs, yet the hive itself stayed compact. The cloned Queen extracted from Ripley 8 established her nest in the ship's waste tank near the docking bay. Cocooned victims included roughly half the science team and several soldiers. When Ripley 8 fell into the Viper Pit, an Alien Warrior dragged her to the waste tank, where she witnessed the birth of the Newborn, who immediately killed the Queen. Ripley and the Newborn escaped before the Auriga crashed into Earth, destroying the hive with the ship.
9. Sevastopol Station Hive
The lone Xenomorph from Alien: Isolation was not alone for long. While Stompy hunted through Sevastopol's corridors, other drones maintained a hive in the lower engineering sections, cocooning victims and moving eggs through the nest. The colony had no Queen, which raises the question of where the eggs originated, possibly through egg-morphing, a process that consumes an additional victim to form each ovomorph. Amanda Ripley destroyed the nest with a reactor purge, and any remaining trace vanished when Sevastopol fell into the gas giant KG-348.
8. Gunnison Hospital Hive
In Aliens vs. Predator: Requiem, the Gunnison hospital hive grew beside the maternity ward and served as the base for the town's rapidly expanding Xenomorph population. Like Sevastopol, it lacked a true Queen; the Predalien bred new Xenomorphs by implanting embryos in pregnant women. Wolf Predator fought the Predalien on the hospital roof, mortally wounding both combatants without a clear victor. The hive might have spread further, but the US Air Force nuked central Gunnison, destroying the hospital and the nest together.
7. LV-426 Atmosphere Processor Hive
The LV-426 hive inside the atmosphere processor from Aliens remains the franchise's most iconic infestation. A smaller nest appears in a deleted scene from Alien (restored in the Director's Cut), but James Cameron expanded the concept into a full colony takeover. The hive spread through sub-level 3 of the processor and held all 156 colonists except Newt, cocooned or dead. Built beneath the primary heat exchangers, the nest had ideal warm, dry conditions for the Queen at its center. She fled when the processor went critical, but the scale of the Hadley's Hope disaster set the template for every major hive that followed.
6. BG-386 Refinery Hive
The Matriarch from Aliens vs. Predator 2010 broke free from Predator captivity, evaded Weyland-Yutani researchers, and built a hive across multiple levels of the Freya's Prospect refinery on BG-386. The nest held hundreds of Xenomorphs with the Queen laying eggs in a central chamber surrounded by combustible containers. That tactical weakness let the Colonial Marine nicknamed Rookie detonate the room and escape. What survived was finished when the Dark Predator triggered a self-destruct device in a nearby ancient Yautja temple.
5. Charon Base Hive
The Charon Base hive from Aliens: Rogue was a deliberately contained infestation: exits sealed, scientists monitoring the colony from outside. Deep inside the mining tunnels of a remote asteroid, Dr. Ernst Kleist, one of the mad scientists who repeatedly weaponized Xenomorph biology, bred roughly a thousand Aliens from victims of his suppressive regime. The hive's defining trait was the smell of rotten eggs from hundreds of cocooned bodies. When a genetically engineered Xenomorph King escaped, the base collapsed in explosions that destroyed both the facility and the nest.
4. DS 949 Terminal Hive
Aliens: Frenzy pushed the Colonial Marine Berserker units beyond their usual small-to-medium hive clearances. A USCM team from the USS Nemesis reached Terminal 949, a deep-space station overrun after a Weyland-Yutani transport carrying Xenomorph specimens docked and the Aliens spread through every level. About a thousand people were infested before the surviving Marines escaped in a shuttle and detonated the station behind them, losing roughly half the unit in the process.
3. LV-1201 Space Jockey Hive
LV-1201 from Aliens vs. Predator 2 hosted several hives, including smaller nests inside Weyland-Yutani structures, but the largest grew inside a buried Space Jockey installation. Over thousands of years the hive merged with the derelict and housed thousands of Xenomorphs bred from both local wildlife and human colonists. An Alien Empress ruled from this lair and commanded other Queens across the planet. Weyland-Yutani commandos briefly abducted her, but the playable Xenomorph from the Alien campaign rescued her before the end of the game. Smaller hives on LV-1201 were destroyed, but the Space Jockey structure itself remained intact.
2. Earth Hive
After Aliens: Earth War, Earth remained infested with Xenomorphs numbering in the billions. Human survivors evacuated or became hosts as hives spread across major cities worldwide. A mercenary squad led by an android duplicate of Ellen Ripley kidnapped the Alien Queen Mother from Xenomorph Prime and dropped her near Oregon, above one of Earth's largest hives and a cache of hidden nuclear weapons. When Xenomorphs across the planet swarmed toward their mother, the bombs detonated and cleared most of the global infestation in a single strike.
1. Xenomorph Prime Hive
Xenomorph Prime, also called Alien Hiveworld, is home to the largest hives in the known universe. The barren surface, its indigenous population long wiped out by different Xenomorph strains, supports massive onion-shaped nests on the surface (based on H.R. Giger's early designs) and equally vast underground caverns. The Queen Mother ruled every hive on the planet and exerted telepathic influence on infestations light-years away. When mercenaries removed her for the Earth Hive gambit, a civil war erupted between the traditional black Xenomorphs and the Red Queen faction. These planet-scale hives appear in both Aliens: Female War and Aliens: Genocide.
Conclusion
Xenomorph infestations scale from a single waste tank to a homeworld turned into one continuous breeding ground. The size of a hive usually reflects how long the Aliens went unchecked and how completely human resistance failed. No matter how large an outbreak on Earth or LV-426 grows, the definitive ceiling remains Xenomorph Prime, the one place where the species was never an invader, but the entire ecosystem.
