Doctor William Magnus, and the Metal Men, storm the office of General Henry Caspar, only to be turned away.

Tin molded himself into a tub, which Mercury filled with his liquid metal form, providing Rome a safe place to splash down.To protect Rome from any potential radiation, Lead molds himself into a suit of armor around her. The Metal Men storm the dome, putting down any military...
