In the year 2074, Earth is under threat from the alien Juralians, a shape‑shifting race with 65 elaborate plans to conquer the planet. Among these schemes are flesh‑eating butterflies, booby‑trapped scientists, an evil doll, a prison break, alien mummies, a pyromaniac child, and a deadly song. The unlikely hero is 10‑year‑old Ken Izumi, who at first glance seems ordinary. In secret he wields weapons, armor, and accessories that transform him into the superheroic Chargeman Ken. As Chargeman, Ken defends his mother, father, younger sister Caron, and his robotic companion Barican, while protecting the rest of humanity from the Juralians’ sinister plots.
