Body Transformation: Klaw’s organic body has been irreversibly replaced with a solid sonic energy. He no longer needs to eat, breathe, drink or sleep. He is not affected by physical or energy attacks although he is very susceptible to sonic attacks and sonic dampening attacks.
Sonic Converter: Klaw’s right hand has been replaced with a prosthetic device that allows him to manipulate sound to fire sonic blasts, project sonic force fields, create sonic objects and create sound creatures.
Ulysses Klaw was a scientist specializing in applied sonic physics. Many years ago, he was assigned a project to produce a sonic converter that could convert sound waves into physical mass. In order to procure a key component, Klaw organized and led several mercenaries to infiltrate the African nation Wakanda to steal a deposit of Vibranium. Coming into conflict with the Wakandans, Klaw ordered his men to kill the leader, T'Chaka, in cold blood. T'Challa, later the Black Panther, witnessed his father's death, and used Klaw's own sonic blaster against him, ultimately shattering Klaw's right hand. Klaw fled back to civilization, and acquired a claw-like prosthetic which had a sonic-force blaster built into it.
Returning many years later to Wakanda, Klaw was opposed by the new ruler, the Black Panther, and the Fantastic Four. At the end of the battle, Klaw threw himself onto his massive sonic converter he had brought along, and was transformed into a creature of "living sound".
