To obtain the Six Elemental Attributes, King Zenoheld has the Vexos search for the Bakugan Brawlers Resistance. Baron, after talking with Ace, decides to move out due to the lack of space in his home occupied by his giant family. While taking his siblings to the park, he runs into Prince Hydron who engages him in battle. All seems well when Nemus pulls out his attribute change ability, but he proves to be no match for Hydron’s Subterra Dryoid. Mega Nemus loses the battle and the Haos energy. Baron must find a way to warn Dan and the others about the Vexos’ return before they get targeted as well.
