Gosei Knight


 * {{nihongo|'''Gosei Knight: is a mysterious warrior of which the Gosei World has no record of. Ten-thousand years ago, he was originally the Groundion Headder (グランディオンヘッダー, Gurandion Heddā?) until he assumed his human-like form to fight the Yuumajuu and was able to cleanse the earth of their influence. When the Yuumajuu return in the present day, Gosei Knight returns to fight them once more. Unlike the Goseigers, Gosei Knight uses the mysterious Knightick Power (ナイティックパワー, Naitikku Pawā?), enabling him to use the abilities of the powers of the Skick, Landick, and Seaick Tribes. When fighting, he refers to himself as "The knight of fate who cleanses the Earth! Gosei Knight" (地球を浄める宿命の騎士！ゴセイナイト, Hoshi o Kiyomeru Shukumei no Kishi! Gosei Naito?). GoseiKnight debuted in Epic 17.
