Power Rangers Ninja Steel

Season 1: Ninja Steel

Galvanax is the reigning champion of Galaxy Warriors, the most popular intergalactic TV game show in the universe where contestants from all over the universe battle to prove who is the galaxy's mightiest warrior. Galvanax is determined to become invincible by controlling the mythical Ninja Nexus Prism, which contains the supernatural Ninja Nexus Star. Master Dane Romero fought Galvanax to keep him from obtaining the Nexus Star and apparently sacrificed himself to thwart Galvanax's plan, while in the process separating the Nexus Star into six separate Ninja Power Stars and creating from the metal of the Prism, the legendary Ninja Steel, though Galvanax and his minions Madame Odius and Ripcon made off with his son Brody. Ten years later, an enslaved Brody escapes from Galvanax's ship with the Prism, the Power Stars, and fellow slaves Redbot and Mick Kanic and returns to Earth, descending into the city of Summer Cove where they meet high school students Preston Tien, Sarah Thompson, Calvin Maxwell and Hayley Foster who manage to retrieve the Power Stars from the Prism and morph into the Ninja Steel Power Rangers. Furious at the outcome, Galvanax sends his warrior contestants down to Earth to steal the Prism where each epic battle against the Rangers is broadcast throughout the universe. Together, the Rangers must master their arsenal of Power Stars, Mega Morph Cycles and Zords, that are all made from the Ninja Steel, in order to stop this evil threat and save the Earth from destruction.^[8][9]

During the final battle against Galvanax, the Ninja Nexus Prism restores Brody's broken Red Ninja Power Star where it not only turns Mick into an alternate Red Ranger, but also restores Master Dane Romero. The Rangers are able to destroy Galvanax with the Ninja Nexus Prism going inactive, but Madame Odius survives the unexpected Ninja Steel meteor attack on Galvanax's ship.

Season 2: Super Ninja Steel

In Power Rangers Super Ninja Steel, the heroic teens find themselves face-to-face with an old enemy when they discover that Madame Odius is still alive and is more determined than ever to steal the Ninja Nexus Prism and revive its powers for her nefarious purposes with the assistance of Badonna, Brax, and General Tynamon. Now it is up to the Rangers and some unexpected help from new friends to use the power of teamwork to protect the Prism, defeat Madame Odius, and save the world.^[3]
