Xenomorph Prime: A Guide To The Alien Homeworld
Xenomorph Prime is the mysterious Alien Homeworld that appeared mainly in Alien games, comics, and expanded universe stories. Although never shown directly in the main Alien films, it was depicted as a hostile hive planet explored by humans and Predators on dangerous missions. This guide covers every major appearance of Xenomorph Prime and what each version revealed about the Xenomorph species, its hives, Queen Mothers, rival strains, and possible origins.

What Is Xenomorph Prime?
Xenomorph Prime is usually treated as the ancestral hive world of the Alien species in the Expanded Universe. It has also been referred to as G-435, the Alien Homeworld, or the Alien hiveworld depending on the source. Most depictions show it as a barren, hostile planet dominated by Xenomorph hives, giant Queens, royal jelly, and endless Alien swarms.
Xenomorph Prime in Aliens vs. Predator: Requiem
The only connection to Xenomorph Prime from the movies comes from Aliens vs. Predator: Requiem. Although we only see Yautja Prime in the movie, original concept art shows that an Alien planet was planned to be used as well. The art shows a desolate planet similar to LV-426 with the surface covered with Alien eggs. It is unknown if Wolf was supposed to travel there before going to Earth or if the plan was to use a completely different story, unlike the final movie. The Alien homeworld was probably cut for budget reasons as well.
Start With Alien Comics
Theory of Alien Propagation
Aliens: The Theory of Alien Propagation was a short comic released by Dark Horse after the successful Outbreak series concluded and before Nightmare Asylum started its run. The comic was written as an in-universe report by Dr. Orona, a human scientist who was an important character in Outbreak and an advisor to the Colonial Marines. It theorized on the Xenomorph's reproductive cycle and described compelling tidbits about the Xenomorph Homeworld. Besides again showing the barren rocky landscape with a hellish sky, it introduces a new species of creatures on the planet that were natural predators for the Xenomorphs. These pale-skinned lizard-like creatures had dorsal tubes and were shown attacking a Xenomorph hive en masse, with both sides taking losses. Perhaps this was where the Xenomorphs inherited their dorsal tubes from.
Human Missions To Xenomorph Prime
Several human expeditions reached Xenomorph Prime in the older Alien Expanded Universe. Most missions were motivated by military research, corporate greed, royal jelly extraction, or desperate attempts to control the Alien infestation on Earth. Almost all of them ended with heavy losses.
Xenomorph Homeworld in Aliens: Outbreak
The first human mission to Xenomorph Prime (also known as G-435) occurred in Aliens: Outbreak (in the year 2192 in the Alien Timeline) and was headed by Sergeant Wilks (an alternate version of Corporal Hicks). Accompanied by a squad of synthetic Colonial Marines and Billie (a version of Newt), his objective was to secure live Xenomorph specimens for study and bring them back to Earth. The hive world they set down on was a barren desert with big rock formations and huge dome-shaped hives. Under a purple sky, the marines were first attacked by green flying creatures (not Xenomorphs), which indicates that the Aliens were not the only creatures on the planet. After getting massacred in a hive, the surviving marines retreated to a dropship and were about to be wiped out. However, a single Space Jockey appeared and obliterated the Xenomorphs with his energy weapons. Wilks, Billie and a surviving android named Mitch Bueller left without any specimens but the humans were soon to return.
Alien Homeworld in Aliens: Female War
The second human expedition to Xenomorph Prime occurred in Aliens: Female War, after the events of Nightmare Asylum. The goal of the mission was to acquire the Alien Queen Mother and bring her to Earth. The Alien infestation on Earth would then be subjugated under her and move to one specific location where they would be vulnerable to nuclear weapons. Leading the mission was an android version of Ellen Ripley with the help of Wilks, Billie, and some mercenaries. The Xenomorph Prime depicted in the comic was a barren wasteland, with giant egg-like hives and no other lifeforms but the Xenomorphs. The mission was a success and the Queen Mother was removed from the planet, resulting in the liberation of Earth from the Aliens.
Start With Alien Books
Grant Corporation's Mission In Aliens: Genocide
The third human expedition to Xenomorph Prime was funded by the Grant Corporation to replenish dwindling supplies of Alien Royal Jelly, the key ingredient behind the controversial performance drug Xeno-Zip. Daniel Grant joined the mission aboard the USS Razzia alongside Major Alex Lee, a platoon of Colonial Marines, and corporate scientists. Tensions escalated when Lee discovered Grant's team was secretly incubating a chestburster to engineer a new Queen, a plan that was sabotaged before it succeeded. After landing, the Marines exploited the ongoing Alien civil war, eventually wiping out the red hive with a nuclear strike and killing its Queen. This weakened the planet's defenses enough for the team to breach the black hive, kill the Black Queen Mother, and extract large quantities of Royal Jelly. The mission succeeded, but only after heavy casualties, betrayal within the ranks, and Lee herself being badly wounded during the final escape.
Aliens: Harvest Mission to the Alien Hiveworld
The fourth human mission to Xenomorph Prime was much smaller in scope than the last ones. This time, Dr. Stan Mayakovsky needed some royal jelly for his personal addiction. Accompanying Mayakovsky was Norbert, a robot Alien. Ultimately, Mayakovsky died on the planet but some humans accompanying him were able to escape. The Alien homeworld depicted in the comic was again barren with strangely formed rocks and a desert-like landscape. There seem to be fewer Aliens on the planet than before, possibly a result of the Alien Civil war from Aliens: Genocide.
Xenomorph Civil War
A Xenomorph Civil War erupted on Xenomorph Prime between the second and third human mission. By the time humans returned to Xenomorph Prime, the hive world was already in chaos. With the original Queen Mother removed years earlier, the Aliens had fractured into two rival strains locked in a brutal civil war. One faction consisted of the familiar black Xenomorphs, while the other was a mutated red strain led by its own Queen. Entire regions of the planet were consumed by constant hive-on-hive slaughter, with swarms of Aliens tearing each other apart in massive numbers. This internal conflict proved to be the only reason a human landing was possible at all, as the Xenomorphs were too busy exterminating one another to immediately overwhelm the incoming Marines.
Predator Encounters On Xenomorph Prime
Xenomorph Prime was not only a target for human expeditions. Several Predator-related stories also treated the Alien homeworld as the ultimate hunting ground, a place where only the strongest Yautja could survive for long.
The Orion Nebula in Alien vs. Predator SNES
In the Aliens vs. Predator SNES video game, a single Predator traveled to an Alien planet in the Orion Nebula. The planet had the characteristics of Xenomorph Prime and most likely was supposed to be the same planet seen in the comics. The surface was covered with rocks and a hive-like substance. Many different Xenomorphs attacked the lone Predator before he finally encountered the Alien Queen. The Alien Queen was defeated and the lone Predator left the Alien world with his trophies.
The Alien Planet in Aliens vs. Predator 2010
Xenomorph Prime showed up briefly in the Predator campaign ending of the Aliens vs. Predator 2010 video game. The Lord Predator bio-mask was obtained by Dark Predator, one of the three protagonists of the game. The mask contained the location and a hologram of the planet, with Alien eggs and juvenile Xenomorph Queens being shown on the initial scan. Dark set his course to the planet and the ending was left open for a sequel which would have possibly taken place on Xenomorph Prime.
Hive Wars Predator's Desolation on Xenomorph Prime
The Hive Wars Predator was stranded on the Xenomorph Homeworld for years after his fellow hunters were killed and their Predator ship broke down during a hunt gone wrong. The lone Predator had to rely on his skill and craft new weapons from the Predator ship wreckage to survive. He encountered and killed dozens (if not hundreds) of Aliens before finding a way off the planet. The Hive Wars Predator was a Kenner figure from the 1990s that NECA created a new version of. He was also featured in the Predator: Life and Death comic series where his badassery ended and he was killed by Colonial Marines.
Is Xenomorph Prime Canon?
Xenomorph Prime exists mainly in Dark Horse comics, games, and expanded universe material rather than the core Alien film timeline. While it is not part of the modern movie canon in a strict sense, it remains one of the most famous interpretations of an Alien homeworld. The concept became especially important in older Alien lore because it gave the Xenomorph species a larger ecosystem, a home planet, and a social structure beyond the hives seen on LV-426.
Prometheus and Covenant Contradictions
The Xenomorph origin (and homeworld) lore depicted in the two Prometheus movies is somewhat conflicting with what was established previously in the Alien comics. In Prometheus, the Engineers experimented on the Black Goo Pathogen on LV-223, resulting in strange mutations. A Xenomorph mural is depicted in the Engineer facility, hinting that LV-223 was perhaps their original homeworld. However, in Alien: Covenant, Ridley Scott implied that David developed the Xenomorphs on "Planet 4", another Engineer planet (but possibly not the Xenomorph homeworld). In the Alien: Covenant novelization by Alan Dean Foster, it's described that David only re-created the Xenomorphs based on the Engineer designs and that Planet 4 is not their homeworld.
Final Thoughts
Xenomorph Prime remains one of the most mysterious and hostile locations in Alien lore. Across comics and games, it was portrayed as a brutal hive world filled with towering hives, Queen Mothers, rival Alien strains, and dangerous resources like royal jelly. Human and Predator incursions to Xenomorph Prime were usually driven by scientific curiosity, survival, hunting, or corporate greed, but almost every mission ended in disaster. Although later Prometheus-era stories complicated the idea of a single Alien homeworld, Xenomorph Prime remains the most iconic version of that concept in the Expanded Universe.
