In the mirror universe, Druja was a Klingon military officer who served in the Klingon Imperial Fleet during the 24th century. He was a member of the House of Ajaq.
In the 2340s, Druja commanded the IKC Tlhab and led the ship into an engagement with the Terran rebels of the Lakul. Druja was killed in hand to hand combat with a shapeshifter impersonating Guinan. The shapeshifter then impersonated Druja's voice to stop the Tlhab from destroying the Lakul. (STA - Mirror Universe- Shards and Shadows short story: "The Traitor")
