Ulysses Klaw

Ulysses Klaw is a villain with sonic powers

The Avengers: Earth's Mightiest Heroes
Klaw first appears helping HYDRA to steal Vibranium from Wakanda. The Grim Reaper soon decided Klaw had outlived his usefulness and attacked him. The overcharged Vibranium turned Klaw into a living sound creature. Iron Man and Ant-Man stopped Klaw by containing his sound emitter (that had become the "heart" of the creature) inside a hollow Vibranium spike.

Ultimate Spider-Man
Klaw is a member of the Frightful Four. After Trapster, one of the Four, is defeated by Spider-Man, the rest of the Four attack Midtown High School with the belief that Spider-Man is one of the students. They escape before the police arrive, but are later defeated by Spider-Man and his team.
