Origin

The criminal scientist Ulysses Klaw, sought to steal the sound-absorbing ore known as Vibranium from Wakanda to power his sound transducer, a device capable of converting sound into solid mass. In the process of his crime he killed the Wakandan king T'Chaka.


T'Chaka's son T'Challa (Black Panther I) used Klaw's own weapon against him, disintegrating the right hand of his father's killer. The criminal scientist swore revenge and would later return to Wakanda to challenge the Black Panther and his new allies the Fantastic Four. Facing defeat Klaw decided to gamble on a bid to become superhumanly powerful by leaping into his sound converter, a decision that converted him into a being of pure sound. He would return again and again, constantly plaguing the African leader and his allies as the master of sound called Klaw.
