The Dragozaur's base begins to crumble without a supply of life force, and Diamond Ryugu sends Drago Wing to Earth to command an army of bite lice. At the same time, Rick visits the Dinotarium for the first time while staying over at Kaito's home. Soon, a miniature Drago Wing and his bite lice army invade the Earth, covering it with Diamond Ryugu's dark energy. The Dino Knights are disabled, and so the kids venture out to observe what is going on. The bite lice are deployed and begin covering everything in sight, terrorizing the city's inhabitants, as Diamond Ryugu begins a search for something important to her on Earth. Rick summons the Cerasaur brothers to help fight the bite lice, and after Dino Ictheo and the Dino Weapons join the fray, discover that the lice are afraid of chickens, they are all able to drive the lice away. Unfortunately, their victory is short-lived as Diamond Ryugu finds and kidnaps Dino Ramph, for use in a giant planet-killer life force extractor. All of the assembled Dino Knights then begin a final desperate attack on Ryugu and her device.
