With Bakugan Interspace beginning to collapse on itself, Mira and Keith attempt to save Mylene and Shadow, despite her wishes to die rather than face dishonorment. Before she can change her mind, she and Shadow fall into the Death Ball's portal while Mira and Keith are extracted from Bakugan Interspace safely. Meanwhile, King Zenoheld learns of Mylene and Shadow's fall and blames their lose, as well as the Resistance obtaining the Alternative data, on his son Prince Hydron who he has tortured as a result. Later that night, Hydron has a dream in which Volt and Lync appear to him and tell him to take down his father and take the throne for himself. Though frightened by the dream, it motivates him to fight against his father. Meanwhile, Zenoheld's bakugan Farbros has been repaired and synchronized with the Alternative System. Hearing this, Hydron challenges his father and Prof. Clay transports them to the arena. Though Hydron quickly gains the upper hand, he is no match for Zenoheld's Assail Farbos. He loses and Zenoheld admits that they were never meant to be father and son and has Hydron imprisoned. While in his cell, Volt and Lync reappear telling him to overthrow Zenoheld. Hydron shouts he will defeat his father, while Gus Grav, presumed to have been killed in episode 39, listens from another cell.
