Beatrix (Earth-5875)

Beatrix was an Auton synthetic science officer at an UNSC base on Ursa IV.

Biography
During a normal work at an UNSC base on Ursa IV, Beatrix had to fend for herself with the arrival of the Covenant and its occupation of the planet. During the bloody battle, the Covenant sent nearly endless waves of jiralhanae in the hopes of slaughtering the human forces at the base. After a subsequent attack, Beatrix's internal musculature was injured and she started leaking. With the little time she had, Beatrix was able to contact First Sergeant Jessica Kress, the highest-ranking Marine in the field following the deaths of all commanding officers, and offering her assistance in order to evacuate the soldiers at the expense of her own life.

With Kress assuming the command of the Marines, she ordered the synthetic to call for UNSC assistance. After the Covenant dispatched new jiralhanae soldiers, Beatrix revealed they were attempting to breach the base through its western sector. Despite the best efforts of the Marines, they were slaughtered by the Brutes, and Beatrix briefed Kress about their falling numbers. As Jessica and another Marine were able to retreat in a M12 Warthog, Beatrix contacted the Sergeant, apologizing before being ripped in half and killed by a jiralhanae warrior.
