Sergeant Rex Power Colt is the protagonist of Far Cry 3: Blood Dragon. He is a Mark IV Cyber-Commando who is part man and part machine. Sgt. Colt has a rather sarcastic and humorous personality, using many one-liners and cynical remarks. Sgt. Colt is also very impatient and enjoys killing, such as when he taunts fallen enemies to "send for a medic so I can kill him too!" Rex is also prone to use sexual innuendo, such as "that's my kind of blowjob" and "guess I blew my load" after using explosives to dispatch his enemies.
