Bakugan Battle Brawlers - Season 4 Episode 16 A Hero Returns

Dan arrives back in Interspace much to everyone's shock and attempts to use Zenthon to shows the others that he and Drago are finally in control of their powers. While at first Drago and Zenthon are battling well, the latter is suddenly no longer under Dan's control and Mag Mel receives a massive flux of power. Anubias and Sellon retreat as the Brawlers leave the section of the Interspace which is then deleted by Marucho. Before departing, Spectra informs Dan that he has changed greatly and that the Brawlers aren't the team they used to be. The rest of the Brawlers mercilessly pile on Dan for leaving them to fend for themselves. Suddenly, Mag Mel and Razenoid break free and Mag Mel assembles a massive force of Bakugan. Later that night after being frustrated by his friends' hurtful words, Dan sees a vision of Gundalia being attacked by Chaos Bakugan! Marucho, Shun, Rafe and Paige prepare to head out to help Gundalia with the intention of leaving Dan behind due to the danger he represents. However, Dan insists on coming stating that he is the original Battle Brawler and will not be cut out off this fight.
