Red Rangers from 10 different teams come together to stop the Machine Empire from using Serpentera to destroy Earth. General Venjix, a servant of Power Rangers Zeo foe King Mondo, seeks to carry on his fallen King's legacy. Andros, the Red Space Power Ranger, discovers Venjix and remnants of Mondo's empire are preparing to invade Earth and retreats to Earth to alert the veteran Power Ranger, Tommy Oliver, of what's about to unfold. Tommy then recruits all of the former Red Rangers as well as the Red Wild Force Ranger, Cole Evans, to make a daring trip to the Machine Empire's hideout on the Moon and stop them.
