Call (Earth-5875)

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

- - Isabel

Call (serial number CLL557-3) 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 the Conestoga-class destroyer UNSC Auriga. In secrecy, she knew the true nature of their deliver, and sought to kill Ripley 8, a clone of the late Ellen Ripley, before a Gravemind could be gestated from within her. Following their delivery, an accident caused many xenomorph that were being held as experiments to escape, she and her fellow crew members allied with Ripley and three other survivors to escape from the Auriga aboard the Betty.

Early life
Isabel was designed and manufactured on September 4th, 2510 as part of the improved Auton synthetic models. She served as the caretaker of a widowed old woman in Ciudad de Arias, Verge, taking care of her as the family did not want to move her to an asylum. One day, she woke up to find her owner dead, which she discovered had committed suicide. Isabel left the scene, fearing for her decommissioning as cases such as those led to the blaming of synthetics and no fair trial.

In 2549, Isabel was recruited by Franklin Elgyn and Sabra Hillard to join the crew of their smuggling ship Betty, in Angoulême, Oban, after saving their life while they escaped from SWAT forces, where she interfaced with the vessel and fled the scene. The couple saw value on her synthetic capability and engineering prowess, and soon hired her to work for them. As a newcomer, however, most of the crew treated her badly, commonly Ron Johner. Despite this, she found a new friendship in Dom Vriess, who reminded her of her old owner, while Vriess took sympathy for her nature as a synthetic, knowing well the pain of prejudice duo to his leg prosthetic.

Personality
"Since when were you in charge? Since you were born without balls!"

- - Ron Johner and Isabel 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 an artificial limb following a firefight on Kawlang. 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 Dr. Mason Wren when he promised he would leave her and her crew mates alone.

Call's compassion drove her to help Ripley 8 destroy the local xenomorphs infestation in order to save humanity from facing extinction. Even though being a synthetic, Call adheres religious beliefs, having a strong faith in God, but believed she would not go to the afterlife duo to her nature as a machine. In order to cope with tragedies, she developed a dark sense of humor during tense situations.

She showed signs of self-disgust as a synthetic, with once she stating she looked disgusting to Ripley 8 and Lance Corporal Vincent Distephano. When Cutter ordered her to interface with the mainframe of the Spirit of Fire, a role Isabel took over from the late Serina, she showed uneasiness duo to how much time she spent without doing so.

Equipment
Although Call is a pacifist by nature, when she needed to wield a weapon she prefer using a combat knife. She always carried two of them in her pockets, and almost attacked Ripley 8 with one of them. She later armed herself with a M363 sticky detonator, which she smuggled from Dom Vriess after his death.
