Leon Kowalski

Leon Kowalski is a Nexus-6 replicant who, along with Roy Batty, Zhora, and Pris, escapes from an off-world colony and returns to Earth. He is a combat and labor model, and his primary motivation is to extend his four-year lifespan. Leon tries to infiltrate the Tyrell Corporation as an employee and, confused by the questions of a Voight-Kampff test, shoots the tester, blade runner Dave Holden. Later he attacks Rick Deckard on the street after seeing him kill Zhora, and is shot dead by Rachael with Deckard's gun. Leon is portrayed by actor Brion James.
