Clare McConnell

Actor (Dennas) — Discovery

Canadian actor and comedian who played Dennas, the leader of a Klingon great house, under heavy prosthetic make-up in the first season of Star Trek: Discovery, appearing in the premiere and the finale.

Clare McConnell is a Canadian actor and comedy performer who joined Star Trek: Discovery in its first season as Dennas, one of the heads of the Klingon great houses.
Dennas is first seen in the two-part opening story, The Vulcan Hello and Battle at the Binary Stars, when T'Kuvma summons the leaders of the houses and asks them to unite against the Federation. She is among the first to be swayed by his call. The character returns in the season finale, Will You Take My Hand?, when L'Rell addresses the assembled houses on Qo'noS.
Like the rest of the Klingon cast, McConnell performed beneath full-head prosthetics and delivered her lines in the Klingon language.
