45

With help from Worton and Betadron, the Brawlers travel back in time to stop Mechtavius Destroyer from destroying Bakugan City, New Vestroia, and more, saving the lives of Runo, Julie, Mira, Kato, and their old guardian Bakugan in the process. Mira and Julie decide to go help them out, but Runo stays behind to send the Battle Suits to the Brawlers. The Brawlers use Bakugan Combinations to counter Mechtavius Destroyer, but are easily defeated. Shun and Marucho summon Flytris and Thorak for help, while Dan summons Dragonoid Destroyer. However, Dragonoid Destroyer only fights at 90% of his energy, stating that "Not everyone is here yet". Mechtavius Destroyer then uses his powers to destroy Volcano Island, the location that had once been the hideout for the now-disbanded Nonets. Gunz considers giving Reptak to Dan due to his lack of knowledge of Bakugan Combinations, Battle Suits, Mechtogan, and Mechtogan Destroyers, but Reptak firmly states that they are partners 'til the end. Mechtavius Destroyer then fires a strong blast at Gunz and Reptak, but at that same moment, Reptak spawns a Mechtogan: Chromopod! Dragonoid Destroyer then announces that everyone is here.
