Dan, Runo, Mira and Baron arrive on Earth safe and sound, but the Dimension Transporter also drops off unwelcome visitors; Lync, Gus and Spectra. Spectra evades capture by taking Runo hostage, setting off a Battle Brawlers manhunt in the snowy foothills outside Dr. Michael's lab. Gus leaves Lync to handle Baron but the cocky Vexos is stunned when Baron not only defeats him, he also totally burns out his mechanical Bakugan. Dan and the others confront Spectra, who stuns them all by asking them to join him in his battle to remove Prince Hydron from the throne. Julie and Dr. Michael find a way to send Spectra and Gus back to New Vestroia, trapping Lync and the others on Earth. But the seeds of doubt have already been laid. To save their Bakugan friends will the Battle Brawlers Resistance have to trust their worst enemy?
