Ronan (The Tsuranga Conundrum)
From Tardis Wiki, the free Doctor Who reference
Ronan was a Clone drone from the 67th century. He was the consort of General Eve Cicero. When the Tsuranga hospital ship was attacked by a Pting, he and Yasmin Khan were instructed by the Thirteenth Doctor to protect the ship's anti-matter drive.
When Eve died, he and the other passengers recited a special incantation in her memory. Ronan told Durkas that, having come to the end of his service with Eve's death, he would be shut down. (TV: The Tsuranga Conundrum)
