Junk Man (ジャンクマン Jankuman?) is a Robot Master created by Dr. Albert Wily to search for parts that could be used to create robots. Junk Man's body is made from old robot parts and metallic pieces of garbage held together by electromagnetic forces. Because of his strength and resistance, Wily decided to modify him for combat. Junk Man can concentrate the electromagnetic forces to pull junk near him, using it for attacks like a block of junk and the Junk Shield. His weakness, the Thunder Bolt, disturbs the electromagnetic forces inside his body, thus making his body parts unable to hold their connection and shatter.
