Aegis VII Queen (Earth-7149)

"Each one of these things comes from an egg, right? So who's laying these eggs? I'm not sure. It must be something we haven't seen yet."

- - Ellen Ripley and Bishop

The Aegis VII Gravemind was a xenomorph Queen born on the human colony Aegis VII in June 2560. Following the outbreak on the settlement of Hadley's Hope, it led the xenomorphs on the planet, later encountering and facing a unit of the UNSC Marine Corps aboard the Conestoga-class light destroyer UNSC Sulaco.

Birth
In the initial stages of the outbreak at Hadley's Hope, on Aegis VII, one of the xenomorphs evolved into a Queen after acquiring enough biomass and calcium necessary to reach mass intelligence, quickly establishing a nest within the colony's crater. Once it reached its full size, it started creating Ovomorphs from the human corpses and all calcium it could moister, creating hundreds of Drones and Warriors that brought any surviving humans as hosts.
