Klaw is later freed from prison by a member of the extra dimensional race of Sheenareans, who wish him to use his sonic powers to help open a dimensional portal big enough for their invading armada to enter Earth. Klaw agrees and after a skirmish with Ka-Zar in London, he travels with the Sheenarean to the Savage Land where there is a vibranium deposit large enough to create the portal. After Ka-Zar repulses the invaders, Klaw flees into the Sheenarean dimension, and unable to salvage anything substantial from his allies, uses their technology to return to Earth.
