In the final episode, the giant finishes toying with Underdog and bats him back to the hospital. With Underdog out of the picture, the Army, Navy and Air Force is called into action against the giant. The giant conquers all the armed forces. Polly explains to Underdog that they were all defeated. Hearing this, Underdog tries to leave, but Polly grabs him by the charm around his neck. In the tug-of-war the charm breaks and Underdog is no longer dizzy. Underdog faces the giant and then punches him so hard, he lands back to his home planet.
