A Klingon house leader who threatened L'Rell and Ash Tyler over their secret child and was killed with Philippa Georgiou's help.
Kol-Sha is a Klingon house leader who appears in Point of Light. On Qo'noS he learns that L'Rell, the new leader of the Klingon Empire, and Starfleet officer Ash Tyler, formerly the Klingon Voq, have secretly had a child together, and he threatens to kill them both.
The pair kill Kol-Sha with the help of Philippa Georgiou, now an agent of Section 31. His challenge leads L'Rell to convince the Klingon High Council that Tyler and the baby are dead, while the child is taken to a Klingon monastery and Tyler is recruited into Section 31.
