BT The Final Battle - S2.E41

Spectra offers Dr. Clay a place by his side and the secret to Bakugan DNA, however, Dr. Clay remains loyal to Zenoheld and declares that he and Spectra are no longer father and son. A battle soon begins between Hydron and Dan and Mira, just as Spectra arrives to fight alongside Dan! Mira is quickly taken out just as the others arrive, too late to warn Dan about the Palace sending power to mechanical Bakugan. Spectra brings out his Battle Gear for Helios and easily takes down Hydron, prompting Zenoheld to enter battle. Despite their power together, Zenoheld overpowers them with a last resort power transfer and takes the Pyrus attribute energy, making the BT system fully operational. Unfortunately, Farbros is completely destroyed in the process. With the BT System fully active, the fate of New Vestroia's residents is grim.
