Daniels, played by Katherine Waterston, is a character from the film Alien: Covenant.
"Danny" is a terraforming expert serving aboard the colony ship Covenant. She awakens from cryosleep when the ship is damaged by a neutrino burst from a nearby star, resulting in the death of her husband and the captain of Covenant, Jacob Branson. When Shaw's transmission is traced back to the habitable Engineer homeworld, Daniels repeatedly states her discontentment with veering off course with the new captain, Christopher Oram.
Daniels joins the expedition down to the surface of the planet, where she discovers Shaw's identification card. When the lander explodes, Daniels prevents Christopher from getting himself killed and is subsequently attacked by a Neomorph. David 8 intervenes, and Daniels joins him and the rest of the survivors back to his base. Daniels orders Tennessee Faris to extract them immediately.
She is assaulted by David, who forces himself on her, but Walter One intervenes, allowing Daniels to reach the cargo lander. The lander is boarded by an Alien, prompting Daniels to exit the vehicle and help kill it herself.
Aboard Covenant, which Daniels is now in command of, another Alien is detected, forcing her, Tennessee and David, (secretly disguised as Walter), work together to dispose of it. Daniels and Tennessee lure the Alien to the terraforming bay, where they impale and eject it into space.
The last human awake, Daniels is being returned to cryosleep by David, who inadvertently reveals his identity by not being able to recount Daniels' fantasy about building a log cabin by a lake, which she had previously recounted to Walter. Horrified, but unable to escape, Daniels is returned to stasis.
