Hiveworld Alien: The planet A6 454 is the Hiveworld of Species XX121, and has been almost completely transformed into a hive. The Queen Mother rules all xenomorphs on the planet, as well as across the galaxy.

Hiveworld Red Alien: Normally all xenomorphs follow the same Queen Mother, but genetic abnormalities can give rise to divergent species, like this red-tinted xenomorph. When a new breed arises, the two species must battle until one is wiped out.
