An unknown creature seeks to devour the sun. The Emperor Armor steps up to stop it, but cannot drive it back. The creature resurrects the Mutant Beasts, Nether Demons, and Cosmic Beasts. Working together, the unknown creature and the Cosmic Beasts overwhelm the Emperor Armor. By chance, Yatales enters the battlefield and joins forces with the Emperor Armor to repel them, but suddenly loses its power. With no other choice, the Emperor Armor sends Yatales’ summoner, Duanmu Yan, back to Earth to seek help from the other Armor summoners, so they can defeat the unknown creature and the Cosmic Beasts together.
