Ulysses Klaw was a physicist working on a device that converted sound waves into physical matter, but needed a metal called Vibranium to complete it. He attacked Black Panther's village, as they had a supply of it, and decimated the tribe with his sound weaponry, but Black Panther turned his own weapon on him, shattering Klaw's hand.
Klaw sought revenge and made a sonic glove weapon that he replaced his hand. He attacked Black Panther again, and was defeated by the Panther and the Fantastic Four. Frustrated, he leaped into his own sound converter, and was transformed into a being made of living sound. With his new powers he could project and shape sound-waves and was virtually indestructible.
