Now that Dan and Marucho are part of the Resistance, they gear up and get ready to fight back against the Vexos, first by heading for Alpha City and the Alpha dimension controller, the machines trapping bakugan in their ball form, to take it down. To get themselves ready, Dan offers to train Baron, whom gladly agrees and can't wait for the lessons to begin but is afraid what will happen when Dan finds out that he was the one who lost Tigrerra to Spectra. But after Lync and Volt were defeated, Spectra Phantom sends out Mylene Pharoah and Shadow Probe to ensure that the Resistance is taken care of. The next day, in the middle of his training, Baron reveals he is discouraged after losing Tigrerra to Spectra in a battle, and says he isn't worthy of the lessons. Just then Mylene and Shadow crash land and Shadow is forced to battle Baron. After losing before, Baron is discouraged and is afraid of losing Nemus the way he lost Tigrerra. But, on the brink of losing Nemus for good, Baron pulls through and wins back three of Shadow's bakugan.
