Voq

Voq is an albino Klingon whose pale skin made him an outcast until T'Kuvma chose him as his Torchbearer in the first season of Star Trek: Discovery. After T'Kuvma died at the Battle of the Binary Stars, Voq was left with a crippled ship and a dwindling crew. With the help of L'Rell, he agreed to a radical surgical and psychological transformation that buried his identity beneath that of a human Starfleet officer, Ash Tyler, so he could infiltrate the Federation. When his true self resurfaced aboard the USS Discovery, L'Rell separated the Voq persona from Tyler's mind.
