The leader of the Ten Rings terrorist cell that kidnapped Tony Stark in Afghanistan, Raza was betrayed by Obadiah Stane, who paralyzed him with a Sonic Taser before his goons slew Raza and his men. His dying words to Tony were for him to not waste his life. Having lost his family in a terrorist attack, Yinsen later sacrificed himself to help Tony escape, suffering fatal gunshot wounds. Ho YinsenĪ captive of the Ten Rings in Afghanistan, Yinsen first saved Tony’s life when he operated on his shrapnel wound and made an electromagnetic plate to keep it from reaching his heart.
