BT: The Final Battle is the 41st episode of Bakugan: New Vestroia. It aired on March 13, 2010.
Spectra offers Professor 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. Fortunately, Farbros is completely destroyed in the process. With the BT System fully activated, the fate of New Vestroia's residents are grim.

Battle Gear Debuts
Battle Gear Seen
- This is the first episode that shows a Battle Gear.
- This is the only episode where Farbros battles without the help of Assail Formation, presumably because it can't be summoned indoors.
- This is the first time Zenoheld is seen battling a brawler, in this case Dan.
- In the Japanese version, there is a deleted scene where Zenoheld is impressed by the destructive power of the Twin Destructor. Oddly enough, that scene was briefly shown in the preview but not in the episode for the English dub.
