|This article is about a/an planet in Kyoryu Sentai Zyuranger.|
Nemesis is the planet where Witch Bandora and her minions were imprisoned. It is a roaming planet which only approaches Earth once every 170 million years.
When Nemesis approached Earth once again for the first time within the memory of modern civilization, an Earth space mission is set up to explore this world, including two astronauts and two children who were chosen for this historic mission. However, the astronauts discover the tomb which Bandora and her minions lay and accidentally open it, freeing all those within. Bandora promptly kills both astronauts and takes the children and the Earth spacecraft hostage before moving her palace initially to Earth. Bandora's return prompted Mysterious Wizard Barza to reawaken the five cryogenically sealed Zyuranger from within their tomb to deal with her.
