Jack Truman was an agent of the international espionage outfit S.H.I.E.L.D. who was badly injured during a mission to capture Cable and subsequently transformed into a cyborg to battle the Red Skull. He later swapped his minds into the body of another former S.H.I.E.L.D. agent, Larry Young. Truman is presumably living a normal human life in Young's body, while Young is presumably still trapped in the Deathlok body.
