Klaw

Ulysses Klaw was an assassin hired to kill T'Chaka, the Chieftain of Wakanda. After doing so, he was wounded by a young T'Challa (who would later become Black Panther). Klaw had his mangled hand amputated and fitted with a claw-like prosthetic device into which he built a sonic-force blaster.

Klaw is the name that Ulysses Klaw now uses. After a second, failed attack on Wakanda, Klaw leaped into his massive sonic converter device, hoping to gain superhuman powers to combat his foe, and was transformed into a creature whose body was composed of "living sound."
