獣神サンダー・ライガー
It is 199X A.D. In Kushiro, Hokkaido, the Drago Knights of the Dragon Empire attack. Possessing overwhelming destructive force, they attack the city to awaken their master, the devil god Jashin Drago from the Rock of Sealing he was trapped in. Two hundred years ago, Drago was trapped in the seal by a holy warrior with the tattooed mark of the Liger. Assuming that the warrior is dead, Drago and Empress Zara are free to conquer the Earth using their army of giant biomechanical beasts. Even the Japan Self-Defense Forces are no match for the Drago Knights' awesome power. One of the people fleeing is the protagonist, a milquetoast 12-year-old 6th grader named Ken Taiga. Unbeknownst to the Dragonites, Ken realizes that he is the descendant of the Lion Clan that once summoned Liger. In a burst of anger, Ken's Liger birthmark appears, and he rises his palm into the air, shouting the henshin (transforming) command, "LIGER!" which then covers him in demonic, long-haired biomechanical armor. Ken transforms into Jushin Liger to fight the evil forces of the Dragon Empire.
