Plot Synopsis

Gosei, a supernatural guardian, has protected Earth for centuries with the help of his robotic aide, Tensou, but when evil Warstar aliens begin their massive invasion, Gosei calls upon five teenagers to protect the planet and carry on the tradition of the Power Rangers. When the teens morph into Power Rangers, they gain superhuman strength, agility, and mastery over martial arts. In addition to defending Earth against the Warstar aliens, other monstrous factions emerge to challenge the Megaforce Rangers. Under the leadership of a malevolent alien, toxic beasts rise from their slimy underground lair to attack Earth, and a ruthless robot army launches an offensive from their deep sea compound. Plus, the alien invaders send a scientist to Earth to study the human race and to identify the best way to defeat mankind.
