SCALPEL. The codename used by Cobra medic, Andrew R. Walker. Walker was born in Death Valley, California. Scalpel got his medical degree through the mail via a small college that advertised in the back of a magazine. His first practical experience came from working as an assistant to a doctor in an illegal clinic treating gang members and other criminals. He eventually joined Cobra not for the money, but for a chance to work on exotic injuries and wounds. While Scalpel's patients have a high survival rate, he is known for a terrible bedside manner, and he is never gentle with his patients. Scalpel enjoys his work, and he doesn't object to picking up a weapon to fight, as long as his side is winning. Scalpel began working for Cobra after the organization's return in 2001. His missions in the field include the battle against the forces of a revived Serpentor on Cobra Island.
