Episode 45:Ground Control to Major Dan

As the Brawlers reach the center of Vestroia, they discover that Naga is no longer there. Meanwhile, Naga appears on Earth to move onto the next phase of his plans. Naga closes the portal that connects Vestroia to Earth, a portal he opened to deliberately lead the Brawlers into and then he begins to open more portals around the world to let in his Bakugan army. Naga's ultimate goal is to capture Wavern and to take the Infinity Core and with the Brawlers out of the picture, it looks like he will succeed. But, Joe doesn't give up and sends a message for help to any and all brawlers willing to fight against Naga and his minions. Battlers from all over the world, including top brawlers Chan Lee, Klaus Von Herzon, Billy Gilbert, Komba O'Charlie and Julio Santana, answer Joe's message and with their Bakugan, go on the offensive against Naga and his team. Komba and Harpus lead one group of battlers against Tayghen, while Julio and Tentaclear lead another group against Tricloid and Billy leads a third team against Rabeeder.

Meanwhile, Chan and Fortress do a 1-on-1 battle against Centorrior and Klaus leads a fourth team against Druman and Hairadee. As the battle rages on, people from all over the world watch as kids and their Bakugan fight to protect the lives of everyone on the planet, and with the support of everyone the battlers are slowly forcing their enemies back. But, things take a turn for the worse when Naga uses the Silent Core to boost the power of his Bakugan and weaken the others. Not only that, but by using using the Silent Core Naga has finally located Wavern! As the Bakugan from all the battlers are defeated Naga's forces, begin to converge on Wavern's location. Wavern in a last stand puts up a force field to protect the city, but everyone is still giving up until they are reminded that they still have the Battle Brawlers on their side. Wavern and Joe are finally able to contact the Brawlers and tell them that Naga has entered their world. Wavern opens a portal to Earth and the Battle Brawlers use it to return home.
