Private Ankor was part of Sergeant Lopé's security team aboard the colonization spacecraft USCSS Covenant. He was serving on the ship 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.
Ankor was first shown in the Alien: Covenant - The Last Supper prologue, talking with Rosenthal about humongous cockroaches living near a colony outpost. In Alien: Covenant, Ankor is shown trying to rescue captain Branson from his hypersleep pod, during the events of the neutrino blast, which proves unsuccessful as Branson is burned alive in his pod. Later, after the blast ends, Ankor accompanied Tennessee in space in order to repair the outside of the Covenant, along with its solar recharge sails. After landing on Planet 4, Ankor accompanied the main group and explored the Juggernaut ship. After travelling back to the lander, with the rest of the crew, Ankor witnessed the lander explode, along with Faris being burned alive in the explosion. He then witnessed Neomorph Bloodburster rip its way out of Hallet's throat and mouth before escaping into the night.
When the two Neomorphs returned to attack the surviving crew, Ankor helped fight the first Neomorph by shooting at it. However, as he did so, the Neomorph spun around and struck Ankor with its tail, slitting his throat, tearing left cheek open, and ripping his lower jaw off, killing him almost instantly.
- In the film Ankor dies when the Neomorph tears through his face and throat by striking him with its tail; in the book the creature pierces the top of his skull with its tail.
