The Cloned Xenomorphs were an altered strain of the species Xenomorph XX121 that were bred aboard the USM Auriga in 2381. They were an aberrant line of the species spawned from the Queen extracted from the clone of Ellen Ripley, known as Ripley 8. The cloning process used to acquire Ripley 8 and, subsequently, the Xenomorphs resulted in the Queen and her Drones[citation needed] becoming altered through the unintentional inclusion of human DNA.
