Bishop (Earth-5875)

"It was a pleasure and an honor to serve with you, Mam. Do look after everyone for me. Goodbye."

- - Bishop's final report

Bishop (serial number: BSP 3510) was a specialized Auton synthetic technician of the UNSC Navy attached to the UNSC Sulaco, a Conestoga-class destroyer, where he served as executive officer. Under the command of Captain Benjamin Mathius and Lieutenant Scott Gorman, he was assigned to coordinate the operations of the 2nd Battalion Bravo during the Battle of Paraíso, where he encountered a xenomorph outbreak.

Early life
Designed on January 7th, 2730, Bishop was the alleged brainchild of the Office of Naval Intelligence operative Colonel Michael Bishop, modeling the synthetic after his own appearance. At the time of his conception, Bishop was considered one of ONI's biggest works, displaying vast intellect and remarkable engineering proficiency.

Sulaco
He was eventually posted aboard the Conestoga-class destroyer UNSC Sulaco as the ship's executive officer and technician under the command of Captain Benjamin Mathius. He adapted fast to the crew, and enjoyed playing knife games alongside Private First Class William Hudson.

On July 27th, 2536, Bishop was presented in the Sulaco when the ship headed to Paraíso in order to investigate a sudden break of transmissions between the UNSC and the colony's main settlement, Hadley. During the voyage, the Sulaco received a new crew member, the civilians Ellen Ripley, which had been put in the mission by ONI thanks to the disruption's possible link with a ship that returned to Paraíso from the moon Acheron, where she had previously met with a mysterious endoparasictic species that killed all of her crew years earlier.

Battle of Acheron
"I'll go. I mean, I'm the only one capable interfacing with the Mammoth anyway."

- - Bishop to Captain James Cutter After awakening from his cryosleep on the ship's route to Paraíso, Hudson asked Bishop to play a knife game once more, but that time to "play unfairly" and use his superior synthetic reflexes to perform it at incredible speeds. Reluctant at first, he eventually accepted, doing it in the front of Ripley, before the play was stopped by Lieutenant Gorman. Despite his seemingly perfect performance, Bishop cut himself during the game, and his white "blood" started protruding from his hand. Ripley saw this, and, duo to her past experience with the synthetic Ash aboard the Nostromo, she became hostile towards him, although he insisted he could never harm a human. This did not convince Ripley, and she demanded him to stay away from her.

As the 2nd Battalion Bravo dropped to the surface of Paraíso in a M510 Mammot, Bishop interfaced with the vehicle and drove it, while the UNSC Marines prepared their weapons for any threat. While the Sulaco remained stationed in the skies, Bishop warned Captain Mathius of the uncertainty of the situations, as their scans did not detect anything. Once they arrived in the abandoned Paraíso, the unit explored an abandoned ONI building, searching audio logs to discover what happened to the colonists who were missing. In that moment, they found captive Facehuggers, and Bishop started dissecting and studying the dead creatures. He continued his work on the abandoned laboratory, while the Marines proceeded to the settlement's Atmosphere Processing Plant to search for potential survivors. He and Connors communicated with the them through a TACPAD.

After most of the Marines died, Bishop and Connors continued studying the Facehuggers in order to find a weakness in the creature that could help the unit combat the xenomorphs with efficiency. Bishop theorized that a yet-unseen xenomorph was coordinating the other xenomorphs to attack.

As the crew of the UNSC Sulaco continued losing personnel on land against the xenomorphs, Bishop decided to take an active role in the situation to ensure the survival of the crew, volunteering to travel to Paraíso's transmitter with a GA-TL1 Longsword, carrying the Spirit of Fire's slipspace drive to use it as a make-shift bomb near the processing plant; the explosion of both would destroy the entirety of the planet and effectively destroy both the xenomorphs. He went, alone and with the drive, to rescue the others. Despite the success of his plan, Bishop had to return when Ripley insisted on going back to Hadley in order to rescue Rebecca "Newt" Jorden, the last surviving human of the colony. He objected, but was forced to return once Mathius ordered him to do so, as they would accompany Ripley stating no innocent would be left behind. The synthetic then flew them back, holding the Longsword until the survivors returned. When they entered the plant, Ripley was able to save Newt, while Bishop left the drive at the plant to detonate it remotely. Alongside Ripley, Newt, and Corporal Dwayne Hicks, Bishop took the Longsword back to the Sulaco, as the Shaw-Fujikawa Translight Engine exploded, taking out the processor plant and Hadley with it, killing all xenomorphs.
