Ulysses Klaw

Solid Sound Body: Klaw possesses a number of superhuman physical powers stemming from his body's conversion into an extra-physical energy form. In some as yet unknown way, Klaw's body is a stable energy form possessing mass and sentience. This form is not bound by conventional human limitations: Klaw does not need food or sleep, nor can he be harmed by penetration wounds, disease, shock of impact, oxygen deprivation, etc. Klaw's body can in fact be vivisected into many pieces without killing him and these pieces can be fused back together by simply touching them to one another. He can only exist in a medium that allows the propagation of sound waves: he would dissipate in a vacuum. Since his body is quasi-solid, he can be touched by physical objects. Although it would cause no permanent damage, a sufficiently powerful blow may not only stagger him but cause temporary unconsciousness. (This occurs when the impact creates a counter frequency that is disharmonious to that of his body). Klaw can maintain his "sonic state" indefinitely. He cannot transform back into his original organic state. His form is resistant, if not immune, to telepathy.

Weaknesses

Vibranium: Klaw's major vulnerability is his susceptibility to Vibranium, the substance that triggered his original transformation. Because Vibranium absorbs all forms of energy including sound, the nearness of a certain quantity of Vibranium can cause the mass of his energy form to become unstable and collapse. Usually when this occurs Klaw's body is absorbed by his own prosthetic sound converter.
