Edward Falcon receives a gift from his father: a mysterious stone. People are all interested in it, including some pirates! They chase Falcon across the city, and he also runs into a swordsman named Ryoma, who apparently has some knowledge of it. Surrounded, the stone causes Falcon to transform into a super-powered, robot fighter, who defeats the pirates easily. Meanwhile, we see that some ninjas have been watching what Falcon's just done. What could all this mean?
Falcon, Ryoma, and Wang-Tang are sent to go after a huge egg for Wang-Tang's master. After many facing traps, Wang-Tang eventually recovers the egg.
