Courtesy of a vibranium -powered sonic converter, Ulysses Klaw was converted into a being composed of psionically "solidified" sound, giving him a somewhat inhuman appearance. The character is described as having superhuman durability and strength sufficient to lift tons of matter. The molybdenum steel sound generator that serves as a prosthetic appliance on Klaw's right wrist is able to transform ambient sound to perform a series of functions, including the projection of intense high-volume sonic waves and blasts of concussive force and the creation of mobile sound/mass constructs. The sound converter was invented by Klaw and later improved by AIM scientists and technicians. Klaw can also sense his surroundings using sonar. When he fought Volcana while trying to abduct Molecule Man he demonstrated the ability to create "cohesive sound". This was essentially an entangling/crushing construct that absorbed ambient noise to increase its size and strength. The noise from the target's struggles to remove the construct would make it larger and stronger. Volcana was only able to escape it by changing into her ash form. After Klaw became temporarily commingled with the ship of the cosmic entity Galactus and reconstructed by Doctor Doom, he became able to create semi-autonomous creatures that he could direct to attack his foes and his creatures are similarly made of solidified sound and display a similar superhuman strength level as Klaw himself.
