Also includes Battle Fever J 3,000 years ago, the Vader Clan devastated Denzi Star. Denzi Land, an island from Denzi Star, landed on Earth. In modern times, the computer of Denziland awoke the Denzidog IC when it detected the Vader Clan approaching Earth. IC found five young people (who may or may not be descendants of the Denzi people) to become the Denzimen in order to defend Earth, the Vader Clan's next target. The Denzimen begin a long record of success with the defeat of Vader Monster number 00, Flying Squirreler. As the battle escalates, they realize that they themselves may be descendants of the Denzi people. If so, they are not alone; other descendants do exist, scattered around the Earth. Queen Hedrian, struggling in her attempts to make the world a living nightmare, receives an offer of assistance from the space wanderer Demon King Banriki. She accepts it, not realizing that ODK's real goal is the conquest of Earth for himself. He captures the Vader Castle and torments the Denzimen with his Omnipotent Monse. Hedrer goes into battle himself giant-sized, only to die a tragic death. The Denzimen find themselves helpless against Banriki and his monster until IC sacrifices himself to become a circuit for the DaiDenzin. Banriki and his monster are defeated. Hedrian escapes to the North Pole, where she sleeps, encased in ice, seemingly defeated for good.
