Xenomorph Prime is a later name for the Dark Horse hiveworld that comics treated as the seat of the Queen Mothers. Aliens: Outbreak and Steve Perry's Earth Hive left that world unnamed. David Bischoff's Aliens: Genocide later cataloged it as G-435, the fourth planet of Achilles Two. Humans and Yautja reached it for specimens, royal jelly, and hunts. Other barren hive planets, including Harvest's AR-32, were later folded into the same label.
What Is Xenomorph Prime?
The first Dark Horse landing, in 1990, never printed a catalog name. Mark Verheiden's Outbreak called it the Alien's world or the genesis world. The 1991 Genocide comic used Homeworld and Hell. Bischoff's 1993 novel gave the official tag G-435, and a staffer corrected an admiral who called it the homeworld. The Marines' name was Hiveworld. It was the fourth of ten planets around the G0 star Achilles Two, a class M world flattened by quakes. Chet Williamson's later novel Aliens: Music of the Spears still called it Homeworld after the Earth war.
Xenomorph Prime began as a fan label around 2007. The first official use was the packaging bio on NECA's 2014 Hive Wars Predator figure. A 2018 Predator app map repeated the name. Free League's Alien: The Roleplaying Game in 2019 went back to G-435 and Achilles 2.4, and never used Xenomorph Prime. The books also disagree on the ground: the comics show dry rock and resin domes, while the Female War novel is a hot, thin-air, high-gravity world with alkaline water over most of the surface.
Xenomorph Prime in Aliens vs. Predator: Requiem
The only film link is unused concept art for Aliens vs. Predator: Requiem. The finished movie shows Yautja Prime, not an Alien world. The cut art is a barren surface close to LV-426, paved with Alien eggs. It is not clear whether Wolf was meant to go there before Earth, or whether the whole plot was different. Budget is the usual reason given for the cut.
Theory of Alien Propagation
Aliens: The Theory of Alien Propagation was a short Dark Horse comic that ran after Outbreak and before Nightmare Asylum. It was written as an in-universe report by Dr. Orona, the scientist who advised the Colonial Marines in Outbreak. The piece walked through the reproductive cycle and put pale lizard-like hunters on the same barren rocks, with a hellish sky over the mounds. Those animals had dorsal tubes and attacked a hive together, with losses on both sides. Orona treated them as a possible natural predator. The comic leaves open whether the Xenomorphs took those tubes from them.
Human Missions To Xenomorph Prime
Three human landings in the older Expanded Universe belong on this world. The first two came from the Earth Hive books and comics. The third was Grant's jelly raid during the red and black war.
Xenomorph Homeworld in Aliens: Outbreak
The first human landing is in Aliens: Outbreak and in Steve Perry's Earth Hive, set in 2192. Sergeant Wilks, an alternate version of Corporal Hicks, left Earth on the Benedict with Billie and a squad of synthetic Colonial Marines. The book never names the planet. Later sources call it Xenomorph Prime or G-435. Massey's sensors read higher gravity than Earth, thin oxygen, extra carbon dioxide, methane, and ammonia, small ice caps, and heat that would cook an unprotected person.
The comic ground is a barren desert with rock towers and huge dome-shaped hives under a purple sky. Green flying hunters that were not Xenomorphs hit the squad first, then the hive itself tore the unit apart. The survivors fell back to a dropship and were close to being wiped out when a single Space Jockey cut the swarm down with energy weapons. Wilks, Billie, and the damaged android Mitch Bueller left without a live Queen. In the novel Wilks seeded dirty nuclear devices before they lifted. He thought the oceans would boil and end the species, but the next ship found a nest.
Alien Homeworld in Aliens: Female War
The second landing is in Aliens: Female War, after Nightmare Asylum. An android version of Ellen Ripley, Wilks, Billie, and a Gateway military crew stole the Kurtz from Gateway Station and followed Queen-of-queens dreams to a nest. They meant to take the Queen Mother to Earth so the hive there would walk onto Orona's unused bombs. The comic ground is dry rock and giant egg-sacs, with crested Palatines around the chamber. The novel never names the planet. It is wet and hot, thin air, gravity about half again as strong as Earth's, and water over most of the surface. The Queen Mother nest sat in the hottest southern belt, as fleshy hive globes in grey water less than a meter deep.
Ripley lured the Queen Mother into the Kurtz hold. A drone bigger than an Earth adult Xenomorph killed two of the landing party at those nest globes, and another crew member died when the ship lifted. The survivors left with the Queen Mother. The book and the comic both stop before the Earth bombs go off. Aliens: Genocide later treats that strike as the event that emptied most of the Earth hive and left this world without its original Queen Mother.
Xenomorph Civil War
After the original Queen Mother was taken, the remaining brood split. Two young mothers divided the planet into a familiar black hive and a mutated red strain, and the two sides tore through each other in the Xenomorph civil war shown in Genocide. Grant's Marines could land at all because the swarms were busy killing one another.
Grant Corporation's Mission In Aliens: Genocide
Daniel Grant paid for the third landing after stocks of royal jelly for the drug Xeno-Zip ran low. He went on the USS Razzia with Major Alexandra Lee (Alexandra Lee Kozlowski), a platoon of Colonial Marines, and corporate scientists. Lee found Grant's people incubating a Chestburster to grow a new Queen. That plan was wrecked before it produced one. On the ground the Marines used the hive war as cover, then wiped out the red mound with a nuclear strike and killed its Red Queen. They took jelly from the black hive. Bischoff's novel has them kill that Queen Mother as well and nuke the black mound on the way out. Lee left with a broken thigh and a wrecked unit.
Predator Encounters On Xenomorph Prime
Later Predator stories used the same hiveworld as a hunt prize, either as a scan of the planet or as a years-long stranding after a hunt went wrong.
The Alien Planet in Aliens vs. Predator 2010
The Predator campaign of Aliens vs. Predator 2010 ends with a scan, not a landing. Dark took the Lord bio-mask on BG-386. The mask held coordinates and a hologram of a hiveworld, with eggs and young Queens on the first pass. Dark set course for that planet. No sequel ever showed him arrive.
Hive Wars Predator On Xenomorph Prime
The Hive Wars Predator began as a Kenner figure from the unfinished Hive Wars toy line, set on a generic Aliens hive planet. NECA's later bio put that Elite on Xenomorph Prime after his clan died and their ship broke down. He built new weapons from the wreck, killed large numbers of Aliens, and found a way off-world. In Dark Horse's Life and Death he was later killed by Colonial Marines on Tartarus (LV-797), not on the hiveworld.
Other Hiveworlds
Later stories reused a dry hive planet, and later labels folded some of them into Xenomorph Prime. The sources below name something else, or stay silent.
AR-32 Vista in Aliens: Harvest
Robert Sheckley's novel of the comic Aliens: Hive, published as Aliens: Harvest, sends Dr. Stan Myakovsky and Norbert after royal jelly on a different world. The comic catalog is A6 454. The novel uses the star AR-32 and the planet Vista, also called the Festerhole, a dusty yellow-grey desert with violent weather from several moons. Bio-Pharm had already run a jelly harvest there, and cows had been brought in as hosts. Julie asked if it was their homeworld. Stan did not think they had evolved there, and treated the original planet as unknown. Myakovsky died on Vista. Some of the humans with him got away.
The Orion Nebula in Alien vs. Predator SNES
In Alien vs. Predator for the Super Nintendo, a lone Predator clears New Shanghai on Vega 4, then follows the infestation to an Alien planet in the Orion Nebula. The game never says Xenomorph Prime or G-435. The last stage was rock and hive resin. He killed an Alien Queen and left with trophies. It is a hiveworld look-alike, not a named return to the Outbreak planet.
Is Xenomorph Prime Canon?
Xenomorph Prime belongs to Dark Horse comics, Bantam novels, games, and later RPG text, not to the core Alien film timeline. The movies never show that world. Older lore used it to give the species a home planet, Queen Mothers, and a civil war beyond the hive under Hadley's Hope.
Prometheus and Covenant Contradictions
Xenomorph origin lore in Prometheus and Alien: Covenant does not match the older comics. In Prometheus the Engineers worked the Black Goo Pathogen on LV-223, and a mural in that facility has been read as a hint that the species began there. In Covenant, Ridley Scott implied that David built Xenomorphs on Planet 4, another Engineer world, and not necessarily a Xenomorph homeworld. Foster's Covenant novelization has David show an egg as Engineer work, not his own invention.
Conclusion
Xenomorph Prime is the later popular name for the Dark Horse hiveworld that Outbreak left unnamed and that Genocide tagged G-435. Wilks's first landing, the Female War capture of the Queen Mother, and Grant's raid during the red and black war are the core of that planet in the Expanded Universe. The films never show it. Harvest's Vista and the SNES Orion world only share the look.
