When the sinister witch Bandora is released from her prison after 170 million years, five warriors from an ancient time arise from their suspended animation to once again defend Earth from Bandora and her evil horde. Armed with enchanted weapons and giant robotic deities known as the Guardian Beasts, it's up to these warriors to defeat Bandora and her monsters before she can exact revenge upon the Earth!
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.
