Eventually the war between Gundalia and Neathia ends as Barodius and Dharak are sent into the dark, reverse dimension of Bakugan Interspace and Nurzak becomes the prime minister of Gundalia after forming a peace alliance with former Queen of Neathia, Serena Sheen, sister of the current queen of Neathia, Fabia Sheen, who with the brawlers and some Gundalian allies they manage to make; little did they know that Barodius and Dharak mutated into Mag Mel and Razenoid.
