Ulysses Klaw

Klaw is a villain obsessed with Vibranium who plans to use it to conquer the world. After failing to get a sample of it from Henry Pym, he hires Whirlwind to get a Sonic Disrupter for him so that he can make the original Black Panther lose his fight to Man Ape so that the big gorilla can restore his tribe and offer him the vibranium for his help.

In "Panther's Quest," while he was in business with H.Y.D.R.A. he ends up fighting Ant-Man until the Vibranium being attacked is overloading and Grim Reaper blasts Klaw into the Vibranium mound turning Klaw into a sound being. Klaw attacks 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.

In Ultima, Klaw was upgraded into a new form, namely, his form from Fantastic Four Ultimate Heroes, which is his sound form in the comics. But Padro Lodo and Dr. Eggman have also experimented on Klaw, giving him the ability to retain his original human self while putting on his comics form as a switch-on costume by pressing a button on his Vibranium blaster. Klaw is currently a member of the Organization, switching between his human, sound monster, and sound human forms between battles.
