When the Winged Warrior ended the alien rebellion, his medieval world returned to normal. On the alien world, the fall of the rebel leader triggered chaos that devolved into civil war. A creature from the Winged Warrior's own world saw the disorder as opportunity. Working with an alien scientist, he traveled to the alien planet and mutated animals from his home into powerful soldier-creatures, building an army the warring factions could not resist. He unified the planet under his own rule. Those who refused were mutated. A small resistance formed — too few to win alone. They reached out to the medieval king, and the king called on the hero he trusted.
