Klaw (real name: Ulysses Klaue) is a recurring foe to Black Panther, the Avengers and The Fantastic Four in the Marvel Universe. A physicist in the field of applied sonics, he lost his right hand after a conflict with T'Chaka, the previous holder of the Black Panther title, which he killed. He would replace his hand with a prosthesis that could turn sound waves into physical matter, as well as create a device that could make him an immortal being made entirely out of sound.
