God Mazingerゴッドマジンガー; 魔神伝説

The plot is about Japanese teen Yamato Hibino, who is sucked through a time warp into the past, where the dinosaur army of the Dragonia Empire threatens the world, and Queen Aira of Mu needs Yamato to help her fight back with the aid of the stone-made guardian God Mazinger, which looks suspiciously like a giant robot.
