Kaizoku Sentai Gokaiger

Kaizoku Sentai Gokaiger is the 35th entry in Toei Company's long-running Super Sentai metaseries, serving as an anniversary season celebrating the franchise's history. The series follows a crew of young space pirates—Captain Marvelous, Joe Gibken, Luka Millfy, Don Dogoier, and Ahim de Famille—who arrive on Earth in search of the 'Greatest Treasure in the Universe.' However, their quest is hindered by the evil Space Empire Zangyack, a massive military force that previously attempted to conquer Earth. Upon arriving, the crew discovers the 'Legend War,' a past conflict where all 34 previous Super Sentai teams sacrificed their powers to destroy the Zangyack armada. Using special devices called Mobirates and Ranger Keys, the Gokaigers possess the ability to transform into any past Super Sentai team, utilizing their unique powers, weapons, and mecha. Throughout their journey, they encounter veterans from previous generations of heroes who test their worth and help them unlock the ultimate powers of the past teams, all while racing against the Zangyack empire to claim the universe's greatest treasure.
