Daniels (aka Dani) was a crewmember aboard the colonization spacecraft USCSS Covenant. She was the wife of Captain Branson. She was serving on the Covenant during its disastrous voyage to Origae-6, during which it suffered several catastrophes that resulted in the loss of most of the ship's crew and its hijacking by David.
Daniels was part of the expedition team that set down on Planet 4. She was one of two Covenant crewmembers to survive the incident, alongside the ship's pilot Tennessee. However, they were captured by David when he hijacked the Covenant, presumably to be used in his future experimentation.
After the first Neomorph was shot dead when two of the creatures ambushed the team, Daniels claimed an AR-15 outfitted with an EOtech holographic sight, dropped by Ankor when he was killed by the creature. While preparing to evacuate Planet 4, Daniels armed herself with a Beretta 92FS Brigadier. She briefly aimed the pistol at David when he approached her threateningly, but he knocked it out of her hand before she could fire a single shot. Shortly afterward, while herself and Sergeant Lopé were fleeing David's compound, she again armed herself with an AR-15 rifle. Later on, she armed herself with a Thales F90 when the Xenomorph born from Chris Oram managed to board the evacuation dropship - however, the rifle proved to be of no use against the Xenomorph and she ultimately discarded it once she ran out of ammo. While hunting for the Xenomorph that birthed from Lopé aboard the Covenant, she again armed herself with a Thales F90, though she never fired it.
