Powers: Superhuman strength and durability greater than Luke Cage. As Power Master he was even stronger and could drain power from sources to amplify his powers even further.
Growing up on the street with his little brother Quincy he became renowned for his street fighting and level head under pressure. After his brother was injured in an accident and had his feet and hand chapped off he became a member of the Maggia’s European division. He worked his way through the ranks until he became division head. He expanded his scope to include even America. His keen insight helped him to stay a step ahead of the FBI, CIA and Interpol. When Misty Knight disguised as Maya Cordy infiltrated his organization he revealed a little too much to her and she eventually revealed her true identity when she saved Iron Fist from his men. He then captured some of Luke’s friends and tried to replicate the power man formula so he could gain superpowers. The formula was a success and now more powerful than Luke he balled Iron Fist, Misty Knight and Colleen wing. His powers were unstable however and after surviving an explosion he slowly became living metal. He tried to find a cure by capturing Luke but with his plans foiled he became a slab of unloving immovable yet sentient metal.
Years later his son kidnapped those who had given John the power man formula in an attempt to perfect it. Their plans were not going as they created power man after power man and all died. When Luke came in his physiology alleviated the fatal side effects. With John and Luke’s bodies he tried to transfer the powers to himself but John reversed the effect become power master as a result he killed his son and drained Luke of his powers. Iron Fist intervened and overloaded John physiology with power until he exploded. He is presumed dead.
