Klaw later becomes a physicist, working in the field of applied sonics. To continue his design of a sound transducer which converts sound waves into physical mass, Klaw steals the metal vibranium to power his device. This is a metal substance known to exist only in certain meteoric deposits in the small African nation of Wakanda. By stealing this rare mineral, Klaw comes into conflict with the Wakandan ruler/superhero T'Chaka, whom Klaw murders in cold blood. T'Chaka's adolescent son T'Challa, who watched his father fall to the invaders, then attacks Klaw to avenge his father. Klaw manages to escape at the cost of his right hand.
