David x Katherine

David x Katherine is the het ship between David 8 and Katherine Daniels from the Alien fandom.

Canon
Daniels was the chief terraformist of the USCSS Covenant, a colony ship that was to transport 2,000 colonists to the planet of Origae-6. Before David began experimenting on Elizabeth Shaw, she recorded a transmission from Planet 4. After a neutrino blast killed all of the colonists aboard the Covenant, as well as Daniels' husband Jacob Branson, who was the ship's captain, the crew members detected the rogue transmission. Following this, the ship's destination was re-routed to Planet 4 to allow for an investigation into the rogue transmission. However, by then, David had already caused the deaths of all of the Engineers on Planet 4, and had already begun experiments on Shaw, which resulted in her death.

Later, after the investigation team had been attacked by Neomorphs, David arrived and scared the creatures off with a flare. He then took the survivors, including Daniels, to his residence. He then explained that he was the android aboard the Prometheus, and claimed that Shaw had perished when the ship they had taken to Planet 4 crashed. He then formed a bond with Walter, the Covenant's android. He then questioned Walter's loyalty to Daniels. When Walter told him he believed it to be his duty, David remained doubtful.

Eventually, after David managed to create the Praetomorphs, he attacked Daniels. He then revealed that he intended to experiment on Daniels as he had with Shaw. David then fought with Walter, which allowed Daniels to escape with the remaining survivors. David later disguised himself as him, with both androids having been based on the same model. He then reunited with Daniels and Tennessee Farris, who by then were the only survivors left, and aided them in killing a Praetomorph. Just before he placed Daniels in cryosleep, she made a comment about her plans for a cabin. When David failed to recall the conversation, she realised his identity, right before he placed her in cryosleep for future experimentation.
