Fictional character biography
Ulysses Klaue is the son of Nazi war criminal Colonel Fritz Klaue of the Blitzkrieg Squad led by Baron Strucker. He was sent by Adolf Hitler to Wakanda to learn their secrets. After World War II, he moved back to Belgium, later anglicized his name to "Klaw," and raised his son with tales of Wakanda.[3]

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.[6][7]
