Samuel Rodriguez, better known as Jetstream Sam or the Minuano, is a cyborg swordsman and the secondary antagonist of Metal Gear Rising: Revengeance. He is Senator Armstrong's minion and a member of Desperado Enforcement LLC.
Samuel's father was the owner of a Kenjutsu dojo in Brazil, their family having a long line of swordsmen. He taught the Uradachi technique, which thought of violence as the final goal. Sam's father was finally killed by one of his students, apparently under orders from a drug cartel. Sam inherited his father's sword and left Brazil, eventually making one last trip back to slay his father's killer, before he left forever. Sam became a wandering mercenary, taking whatever work he could, and made a name for himself in the criminal underworld. There was even one story that said he took down a squad of 10 armed mob hit men using only his sword. Sam eventually got himself a cyborg-esque suit to enhance his already impressive abilities and had his sword, the Murasama blade, modified into a high-frequency blade.
