The first Japanese space shuttle is launched to explore planet Nemesis where the evil Bandora and crew are released. Bandora and her crew immediately set to wreak havoc on Earth. The warriors are captured and must then transform into the mighty Zyuranger.

Bandora returns the Japanese shuttle and the children within it to Earth, setting up a trap to capture the Zyuranger with a powerful DoraMonster.

With their weapons destroyed, the Zyurangers head to the Land of Despair to get legendary weapons, made more difficult when Bandora traps a boy and his mother within.

Gnome's grandson steals a key to reawaken Burai, a legendary hero of the Zyuranger's time whom Barza and Gnome wish not to reawaken.
