Hero Returns.Dan finally returns to Bakugan Interspace to help the Battle Brawlers in their battle against the Chaos Bakugan with his friends and Drago battles Anubias's Horridian, Bolcanon, Krakenoid, Sellon's Krowl, Spyron and Vertexx, while he is able to weaken them in the progress. While Drago is battling, Spectra Phantom and Infinity Helios were impressed of Drago's new power. Also, Rafe and Paige were scared about how much power that Drago had. Later, when Dan says to Drago that he should finish it, Drago summons Mechtogan Zenthon but Marucho and Shun were worried that Zenthon might destroy the place and also the Brawlers too. Zenthon and Drago start defeating a whole bunch of Chaos Bakugan but then, Dan suddenly has a vision of Mag Mel which causes Dan and Drago to go out of sync and they are unable to control Zenthon and he starts attacking Bakugan Interspace. Zenthon also defeats Marucho's Infinity Trister, Rafe's Wolfurio, Paige's Boulderon, Spectra's Infinity Helios and Shun's Taylean in one blow and they all turn back into their ball form. Later after that Zenthon disappears and Anubias summons BakuNano Aeroblaze, BakuNano Hyper Pulsor, BakuNano Daftorix, BakuNano Slicerix, BakuNano Jamsaber and BakuNano Orehammer for Team Anubias' Bakugan and Team Sellon' Bakugan. Drago is then defeated by all of them due to being a six on one fight and they had BakuNano's but when Dan was about to throw Drago back into the battle, Marucho stops him and sends back the brawlers alongside Dan into the interior of Bakugan Interspace. Marucho then deletes Area B and all of the Chaos Bakugan are deleted...
