When the Winged Warrior defeated the alien rebel force that threatened his world, life on the medieval planet returned to normal. But this was not the case on the planet of their alien neighbors. WIth the fall of the rebel leader, chaos erupted. Outbreaks of civil war were commonplace as various groups sought control of the planet.

Back on the medieval planet, a creature had plans of his own for the alien planet. He saw the disorder as an opportunity to rule. While wars raged, he travelled to the alien planet and used an invention to begin building an underground army. Aided by an alien scientist, he mutated animals from his planet into alien creatures with profound strength. He then emerged with his legions of mutated soldiers and took control of the alien planet. Those who did not succumb to the growing empire were met with mutation.

This was just the beginning of the Alien Empire. Time passed and the Empire continued to grow in strength. But not all would follow the emperor.

A small resistance began forming against the Empire. They were few in numbers but were determined to overthrow the evil emperor. But alone they could not do it. So they turned to the king of the medieval world for assistance.

The kind knew what to do. He called upon the hero who had only years before saved his kingdom from the hand of evil... the Winged Warrior.
