Kaizoku Sentai Gokaiger (海賊戦隊ゴーカイジャー Kaizoku Sentai Gōkaijā, translated into English as Pirate Squadron Heroic Ranger) is the 35th season of the Super Sentai series and celebrates the 35th Anniversary of the franchise. It premiered on TV Asahi February 13, 2011, joining Kamen Rider OOO and Kamen Rider Fourze as programs featured on TV Asahi's "Super Hero Time" programming block. The season's motif is pirates and follows the story of five young space pirates in search of the "Greatest Treasure in the Universe".

Its footage and anniversary theme was then adapted into the second season of the 20th Anniversary Power Rangers season, Power Rangers Megaforce, the 2014 Power Rangers Series Power Rangers Super Megaforce.

Plot
The Gokaigers use the "lost" powers of the 34 previous Super Sentai teams to fight the evil Universal Empire Zangyack, whose first wave of invasion forces were completely defeated by the older teams until they arrive with reinforcements and invade the Earth once more, and they must visit the past 34 teams to obtain more power to fight against the ever-determined Zangyack.

As they continue collecting more Greater Powers, the Gokai Crew runs into Marvelous' ex-crew mate, Basco, who is also looking for the Greatest Treasure in the Universe, but he wants it all for himself. To that end, he betrayed his old crew and joined up with the Zangyack. He opposes the Gokaigers with his own set of Rangers Keys and his partner Sally, a monkey-like alien who can summon Giant Battle Pseudo-Lifeforms.

Eventually, Gai Ikari, an Earthling, joins the crew as the newest Gokaiger, Gokai Silver, after obtaining his gear from three former Sentai heroes (Burai, Naoto Takizawa, and Mikoto Nakadai) and proving himself worthy of being a Gokaiger. As a Sentai Fanboy, his knowledge of past Super Sentai teams aids the Gokaigers in their fight against the Zangyack Empire and Basco.
