Storyline

The Challengers are summoned by the Challengers Corps, a group of civilians saved by the team in the past offering to be their "eyes and ears." When a member reports ships disappearing, the Challs respond, but they are dumped on an island with replicas of world monuments, ruled by Korba, a villain without a country. The heroes are pushed into an arena to fight a giant robot, the Iron Emperor. Rocky wallops the robot with new power gloves, but they awaken an ancient "totem" of three monsters. With their own super-gear, Red, Rocky, and Prof each defeat a monster and Korba is taken to jail.
