Bakugan Gundalian Invaders

The Brawlers arrive at Neathia and meet Fabia's sister Queen Serena. With her blessing, Fabia takes her new friends to see the Sacred Orb, a source of great power that is hidden deep inside a mountain.

With only one remaining security shield protecting Neathia from the invading Gundalian forces, the Brawlers hatch a plan to reinstate a previously destroyed shield. Marucho, Jake and Elright head for the frontlines to battle the lead invaders, and provide a distraction.

Dan, Fabia and Shun continue to make their way through the jungle to the shield generator building, when Stoica and Jesse suddenly ambush them.

Having made it to the Generator Building, Shun and Drago find themselves up against an army of Gundalian Guards, as they attempt to restart the Second Shield.

With the Second Shield back up and running the Brawlers help the Neathians rebuild their strongholds. Frustrated that they are losing momentum, Jake strikes out on his own in search of more Gundalians to fight.

When Mason flees his Gundalian ship, Nurzak and Ren are soon in pursuit as they attempt to apprehend him before the Emperor learns of the escape. Before they find him, however, they run into Marucho and Fabia.

Fearing that her life may be at risk, Zenet morphs into a doppelganger of Ren in order to accompany Gill on a mission to destroy the Second Shield.

On the eve of the revolt against Barodius, Nurzak sends a message to the Brawlers asking to meet and discuss a peace treaty.

While Kazarina works on a secret weapon designed to take down the restored Second Shield, the Gundalians dispatch their army of hypnotized Earth kids to distract the Brawlers in battle.

As Ren prepares to launch an attack on the restored Second Shield, something strange is happening deep within the bowels of the Gundalian Palace. Sid, stirs from his medically induced slumber, and finds that he and his other "discarded" teammates are being kept in specimen jars.

Once Kazarina finally completes the upgrades on Exokor, the Twelve Orders descend on Neathia to take down the restored Second Shield.

Ren's conflicting loyalties finally come to a head when he decides to turn his back on Barodius. Furious at the betrayal, the Emperor challenges him to a battle and immediately begins pummeling him.

When the Brawlers are transported back to the Royal Palace, Ren is nowhere to be found. They learn that the Third Shield has been outfitted with a Bio-Filter that prevents anyone with Gundalian DNA from passing through.
