|Real Name||Ulysses Klaw|
|Powers and Abilities||Made of Sound|
Ulysses Klaw was a scientist obsessed with vibranium until he became a creature of pure sound.
After killing the S.H.I.E.L.D. agents guarding the facility, Klaw and his men attempted to take the vibranium from the researcher running the project, Hank Pym. Ant-Man used his abilities to easily defeat the mercenaries, but Klaw escaped before Pym could capture him as well.
He later hired Whirlwind to steal a sonic disruptor from a nearby college, which he replaced his right hand with.
When the Avengers came, he ended up fighting Ant-Man until the Grim Reaper blasted Klaw into the vibranium mound turning Klaw into a sound being. Klaw attacked the HYDRA agents in retaliation. Ant-Man and Iron Man managed to use the vibranium to contain the Sonic Emitter enabling the vibranium to absorb Klaw.
Klaw was voiced by Mark Hamill.
