The Legend of the Power Rangers: Galaxy Heroes is the third season of the Legend series, which is the reboot of the Mighty Morphin era.
After defeating the Prince of Darkness, the rangers hope they finally brought peace back to the world and the Shadow Empire has been stopped once again. However evil never is defeated when Dalin decides to recruit new allies—much more dangerous and much stronger than any creature the rangers have faced. Now calling themselves the Syndicate, Dalin and his allies unleashes all kinds of terror into many parts of the world; Zordon realizes now is the time to have other rangers to join the Nova Rangers into stopping Dalin once and for all. With new rangers, new weapons, and new zords, the Nova Rangers could finally end the empire, but there are much more secrets to the Syndicate’s plan, something that involves the resurrection of the first evil known as the Dominion.
