Katherine Daniels, nicknamed "Danny", was the chief terraformist aboard the Weyland-Yutani Corporation colony ship USCSS Covenant and the wife of ship's captain Jacob Branson. Daniels was part of an expedition team that journeyed to a mysterious world after the Covenant was diverted there from its original destination of Origae-6, and was one of two crewmembers to survive the ensuing incident alongside the ship's pilot Tennessee Faris. However, they were captured by the rogue synthetic David when he hijacked the Covenant; Daniels was of particular interest to the synthetic, with David stating that he planned to use her to create a queen for an alien species he had designed.
