KlawReal Name: Ulysses Klaw

Ulysses Klaw is a gifted scientist whose expertise in sonics is unrivaled. He has spent much of his time seeking to weaponize vibranium.

Klaw and his minions attacked Hank Pym in an attempt to steal the vibranium sample Hank Pym was examining on behalf of S.H.I.E.L.D.

Klaw supported M'Baku the Man-Ape when M'Baku challenged King T'Chaka of Wakanda for the kingship, and used a sonic weapon during the duel to weaken T'Chaka, allowing M'Baku to kill him, thereby becoming King of Wakanda. In exchange, M'Baku has given Klaw access to the Wakanda vibranium supply.

While in the process of making a deal to exploit Wakanada's supply of vibranium, Klaw was transformed into a creature of sound.  After fighting both HYDRA and the Avengers, he was encased in a prison of vibranium.
