This Xenomorph Drone sneaked aboard the Torrens in 2137 and killed the two crew members aboard the ship at the time — Diane Verlaine and William Connor. When Amanda boarded the ship, the Drone was waiting for her. However, she opened the ship's airlock, sending both into space.
The Drone was one of the many Xenomorphs Drones that was born within the hive located in the depths of Sevastopol Station that was established by the Sevastopol Alien that emerged from Catherine Foster in 2137, following her visit to the derelict on LV-426 aboard the Anesidora. The Torrens Drone emerged from one of the Sevastopol residents that was captured and brought to the Hive by the Alien. When Amanda Ripley discovered the Hive, she initiated a reactor purge in an attempt to destroy it, but multiple Xenomorphs, including the Torrens Drone, managed to escape the purge.
When Marlow destroyed the Anesidora in an attempt to destroy the station and his ship to ensure humanity never came into contact with the Xenomorphs again, the station's gravity stabilizers were damaged, causing the station to begin falling into KG348's atmosphere. Amanda contacted the Torrens and Diane Verlaine docked the the ship with the Sevastopol. The Drone sneaked aboard the ship during this time and killed the ship's captain and owner, Verlaine, and the navigator and communications officer, William Connor, who would have likely both been on the bridge at the time.
Once the ship was free from Sevastopol, Amanda, still in her IRC Mk.50 Compression suit, boarded it and walked towards the bridge. However, when she pressed the button to open the door to the hall leading to the mess hall, the Drone was waiting behind it. The Drone slowly approached Amanda, who crawled into the ship's airlock. Once both were inside the airlock, Amanda pressed a button to open it, just as the Drone was about to headbite her, sending both adrift into space , the drone isnt seen again after this ,since Xenomorphs are known to survive in space it's likely it's still alive and is floating in space and is doomed to this forever unless it is found.
- The Drone is the last Xenomorph that Amanda encountered in Alien: Isolation.
- This Drone is the only surviving Xenomorph of the Sevastopol hive.
