*Tales of Suspense #79-81.
The evil Red Skull had stolen the most awesome weapon in the world, the Cosmic Cube--an energy device that could manipulate matter! Relishing his godlike power, the Red Skull repeatedly allowed Captain America to attack him. And each time, when Captain America was about to win, the Red Skull would use the Cosmic Cube to savagely strike him down. Finally, Captain America used the Red Skull's own arrogance as a weapon to defeat him and keep him from ever using the Cosmic Cube again. *Source: Back of Card
