Karl Tirpitz is either a defensive end, linebacker, or defensive back on, and captain of, the Supermax Prison Facility team in Blitz: The League II (his position is dependent on Franchise's offensive position). Tirpitz is serving time in prison for 23 counts of aggravated assault, and is considered the most violent and brutal inmate on the Supermax team. The player first encounters Tirpitz when "Franchise" is sent to Milltown Correctional Facility after testing positive for the illegal performance enhancer Ultranol, and must defeat Tirpitz and the Supermax team in the Prison Ball game for an early release. After completing Division II, Tirpitz joins the player's team.
