Isabel (Earth-2124)

"ONI were breeding xenomorphs here, and now the Brutes have released them. They're more than dangerous. If those things get loose, it's gonna make Boren's Syndrome look like a fucking square dance!"

Isabel was a synthetic Auton and engineering assistant aboard the smuggling ship Betty. Isabel and the ship's crew were hired by the Office of Naval Intelligence to deliver a series of inmates from Midnight Facility to the Henry Lamb Research Outpost at the Ark. Following the arrival of the Banished and subsequently a xenomorph outbreak, she and her fellow crew members allied with the UNSC Spirit of Fire to combat both threats.

Personality
The newest member of the Betty's crew, Isabel was treated with a mixture of disdain and mockery by her fellow mercenaries, with the exception of Dom Vriess, who was her closest friend and understood the prejudice directed at her for being a synthetic, the same way he had artificial limbs following a firefight on Mamore. Despite being a synthetic, perceived as only a machine by others, she was the most caring and compassionate of the Betty's crew, appearing to others as outwardly naïve. While this naïvety could be perceived as something to shield her from others, it had base in reality, as she believed in Decimus when he promised he would leave her and her crew mates alone.

Equipment
Although Isabel is a pacifist by nature, when she needs to wield a weapon she prefer using a combat knife. She always carried two of them in her pockets, and almost attacked Jerome-092 with one of them once he reached the Betty. She later armed herself with a M363 sticky detonator, which she smuggled from Dom Vriess after his death.
