The survivors of Terra Venture were able to establish the first space colony from Earth on the planet Mirinoi, thanks to help from the Galactic Space Alliance. The colony, Terra Nova, is thriving despite growing tensions with the native Mirinoians over the size and scope of the colony and its effect on the planet's environment. Against the advice of the natives, the colony sends a scientific research expedition into what the natives consider the forbidden zone. Eager to learn more about the planet they now call home, the expedition team accidentally unleashes an ancient evil from its prison during their exploration of the planet. This ancient evil known as the Balbadrex Empire and its emperor Zardeus seek to conquer the galaxy as well as enslaving and experimenting on its inhabitants.

Scrambling to find a way to to protect their new home planet as well as the galaxy at large, the former rangers discover an ancient abandoned command center with the help of Alpha 6 and the wise Mirinoian sage Jera. Once inside the command center, they discover a new set of ranger powers and zords. Can these new found powers and zords eliminate this latest evil threat for good? And what will the rangers discover about Mirinoi's forgotten history and the source of these new powers and zords? Tune in weekly to Power Rangers Supernova Squad and find out.
