Dyna-Man

Dyna-Man is the first sequel to Go Rangers, the American remake of Himitsu Sentai Goranger. Despite the series' title, this series is actually an adaptation of Denzi Sentai Denjiman rather that Kagaku Sentai Dynaman.

Story
Many years ago, Dyna-Star was attacked by the Vader Clan, an invasion force led by Queen Setra. In a catclysmic battle, the Vader Clan is sealed with Dyna-Star. In the present day, the Vader Clan is freed and attacks Earth. The five descendants of the original Dyna-Men who fled to Earth become the new Dyna-Men to protect Earth from suffering the same fate as Dyna-Star and avenge their people.
