Triple Threat - S4.E14

The Brawlers, now back together, are dominating as a group and face Team Anubias in the next round. Sellon arrives on New Vestroia and fights Dan and Drago. Although they put up a good fight, Drago is forced to summon Zenthon, who now fully obeys Drago without question. Things take a turn for the worse when Sellon suddenly summons three Mechtogan at once! Dan, Drago and Zenthon combine their power and end up summoning a Mechtogan Titan, which easily wipes out Sellon's Mechtogan. Sellon tells them they can keep their gate and key and that the end of the world is still coming before leaving. Back in Interspace, Chaos Bakugan are suddenly released and are destroying Interspace, interrupting the battle between the Brawlers and Anubias.
