Ep 37. Space Armada

Evil Metallus invites Space Ghost aboard his Man of War, where he shows off his latest creation - metal men. These creatures can track down and destroy any object, anywhere. After the demonstration, Metallus reveals his plan to launch thousands of the metal men in just one hour. But Space Ghost won't wait - he launches a pre-emptive strike while on Inviso-Power. Unfortunately, Metallus has also mastered invisibility, and has many more metal men all designed to track and destroy Space Ghost!
