K'orin is a hard-drinking Klingon general and old friend of Beckett Mariner who later sits on the Klingon Oversight Council.
K'orin is a veteran Klingon general who shares a long friendship with Beckett Mariner, one of the many surprising connections that hint at her past adventures. He enjoys drinking and reminiscing about old battles with her.
In Envoys, Boimler and Mariner are assigned to ferry K'orin by shuttle to the Federation embassy on Tulgana IV. Mariner and the general drink their way through the trip, and after landing a drunken K'orin steals the shuttlecraft. Boimler and Mariner spend the episode searching the planet for him before delivering him to the embassy.
K'orin returns in A Farewell to Farms as a member of the Klingon Oversight Council, the body that rules on Ma'ah's appeal to regain his command. He was voiced by Jess Harnell.
