Xenomorph Prime,[1] also known as the Hiveworld[2] or A6 454 by some human scientists, is the home world of the Xenomorph XX121 species along with several other alien species. Xenomorph Prime is at least the size of the Earth and has three major continents and a small ocean. The hive area of the planet is full of Xenomorphs, and most of the landscape is covered in an enormous Hive, although some deserts, mountains, oceans and some other landscape features are not covered in the Hive structure. There are most likely multiple Xenomorph hives that support one another to keep the planet under their control. It is shown in Aliens vs. Predator that Dark and his clan are headed there for the greatest hunt yet. The Weyland-Yutani Corporation also travels there, seen as Specimen 6 is being transported off BG-386 on board a vessel of Weyland-Yutani design.

Although Xenomorphs are the dominant species of the planet, there are several non-Xenomorph species on the planet which are just as dangerous, if not more so.


  • Unnamed Xenomorph Predators: Pale creatures who compete with the Xenomorph for space. Natural predators of their species, keeping their numbers in check.
  • Xenomorphs: The deadliest semi-sapient species in the galaxy. Xenomorphs are one of, if not the most, fierce and vicious creatures on the planet. Xenomorphs are at the top of the food chain and have few natural 'predators' or enemies.

Xenomorph types known to live here are:

Human and Predator spawned Drones/Warriors as well as Runners won't be naturally found on the planet, this is because these Xenomorphs require a host not native to the planet and thus it would not be their "home world" unless the hosts required for above were to visit or be taken to the planet. 

The Xenomorphs on the planet have been known to spread to different neighboring worlds, and many Xenomorphs, ranging from small Facehuggers to even Queens, are kidnapped and taken off-world by Yautja, their natural enemies, to begin a hunt on worlds such as Earth.


Although Xenomorph Prime is mostly covered in Xenomorph Hive resin, it does include deserts, mountains, oceans, savannas, forests, and tundras.


Xenomorph Prime is home to the Queen Mother, the supreme ruler of the Xenomorph Hive, which is considered to be one of the strongest creatures in the galaxy.

Behind the Scenes

Xenomorph Prime, or the Alien/Xenomorph Homeworld is dealt with in the four first Aliens comics series and in the 2010 video game Aliens vs. Predator.

Some different examples of its habitats are shown in the comics, including mountainous terrain (Aliens: Book 1), desert-like steppes with some greenery (Aliens: Genocide), swamps (Aliens: Female War, Aliens: Genocide) and caves (Aliens: Genocide). Also, some examples of other Xenomorph Prime indigenous species are also shown in these series. There are about four different examples of hives shown in each of the locales.

Queen Mothers: On the issue of the Queen mother of Xenomorph Prime. As per the comics, there was a sort of "super" (not the word used for it in the comics) Queen Mother on the planet that was sending signals out to all the Aliens, at least the ones who had taken over the earth, including the Queens on earth—her signals were also being received somehow by the synthetic Ellen Ripley. This one was captured at its swamp-like hive by Wilks, Billie and the Ripley synthetic, brought back to earth and destroyed. This did serious harm to the Aliens on Earth, but did not wipe them all out (all of this information from Aliens: Female War).

Meanwhile back on the Xenomorph home world, once the Super Queen was dead, the Royal Guards split into two factions with two newborn Queens (one red colored and one black, though the comics editors have said the coloring was just to be able to tell apart the factions and didn't necessarily need to be taken as literal). This lead to a genocidal war between the two factions (red and black) of Xenomorph on the home world (this according to Aliens: Genocide). After the earth had been reclaimed from the Xenomorphs (which took about two years according to Aliens: Crusade), a Grant Corporation mission to the home world sent to try and capture one of the Queens disrupted the war, killing one of the Queens. Meanwhile, Xenomorphs and their hives continued to dot the cosmos.

Hives: The mountainous, temple-like hives on Xenomorph Prime was first depicted in Aliens: Book One. The design was reused in the first AVP comics series for a hive on another planet, then multiple other Aliens comics (such as Aliens: Hive and Aliens: Labyrinth), and eventually in the AVP 2010 video game. The construction of such a hive was shown in Aliens: Theory of Alien Propagation.

Another form of the Alien hive, made up of four pod-like spherical structures connected via rocky tethers in swamp-like area, was first introduced in Aliens: Female War as the home of the Queen Mother and shown again in Aliens: Genocide. The construction of such a hive was shown in Aliens: Genocide.
