What is "goseigers"

The are the fictional protagonists featured in the 34th Super Sentai Series Tensou Sentai Goseiger, making their debut in the film Samurai Sentai Shinkenger vs. Go-onger: GinmakuBang!! where they briefly appear to fight against some of the Gedoushu. The Goseigers fight against several groups of antagonists throughout the series — Universal Annihilation Army Warstar, Earth Condemnation Group Yuumajuu, and Machine Onslaught Empire Matrintis — before facing their true enemy Brajira of the Messiah.

Following the end of the series and the epilogue movie, the Goseigers participate with the 33 other past Super Sentai groups in the Legendary Great War, defeating the first invasion force of the Space Empire Zangyack at the cost of losing their powers. During the events of the film Gokaiger Goseiger Super Sentai 199 Hero Great Battle, the Goseigers regain their powers after stealing their respective Ranger Keys from the Gokaigers and battle them to get Gosei Knight's Ranger Key from them to resume their mission. Eventually, both Super Sentai groups eventually team up to battle the resurrected leader of The Black Cross Army and the Goseigers relinquish their powers once more after finding common ground with the Gokaigers.

Much of the footage and plotline for Goseigers was adapted for the American series Power Rangers Megaforce and its sequel series Power Rangers Super Megaforce.
