Queen Chestburster (Earth-7149)

The Queen Chestburster is a special variant of the standard Chestburster, growing, as it name implies, into a full Queen. Owning to its very special status, those impregnated with a Queen Chestburster are left alone by any xenomorphs to which the Queen telepathically control to allow it to grow, a process which takes much longer than normal.

History
Ellen Ripley was impregnated by a Royal Facehugger with a Queen Chestburster in 2557 aboard the USS Sulaco; the Facehugger's attack led to a malfunction in the ship's systems that ejected the crew into a Type 337 EEV to the penal colony Fiorina 161.

There, Ripley had to fend for her life against countless of dangerous criminals to survive the Dragon, a xenomorph that sought to ensure the Queen would be born. In the end, Ripley killed herself alongside the Queen to prevent the Weyland-Yutani Corporation from acquiring it.
