Bakugan Battle Brawlers (2007)

Season 2: Episode 48

King Zenoheld sends Mylene and Shadow Prove to collect the Brawlers' Battle Gear and Bakugan DNA Data so with the data the Alternative could be finished faster. Having followed Billy to Marucho's house in episode 37, Mylene and Shadow have prior knowledge to their hiding place. Once they arrive, they are ambushed by the Resistance, but Mylene takes Mira hostage! Keith quickly agrees to give them the data in exchange for Mira but instead he leads them to Bakugan Interspace. Despite Mira's attempts to change Mylene and Shadow's mind, a battle quickly follows between the four. Shadow is quickly and effortlessly defeated by Keith and MAC Spyder is destroyed in the process. Mira soon defeats Mylene and destroys Macubass. Keith offers Myelene a place in the Resistance but she bitterly rejects and throws one of Hydron's grenades. However, it results in a portal opening in Bakugan Interspace causing it to collapse, which means if it continues further causing the Interspace to shut down with the four of them still inside, they could be trapped there forever!
