After Shun successfully leads the Resistance into Alpha City, Mira departs on her own mission: searching for her older brother, Keith. She heads to her home to search for clues on her brother's computer but comes up with nothing. After her father, Dr. Clay, arrives, she confronts him and he simply says that "He is no more." When she further questions him, he leaves for his lab, while Mira follows. Meanwhile, Shun takes the others to check out the control spire and they learn that the battles that take place in the arena below the controller are synchronized with the controller's power. At the lab, Mira witnesses the birth of the first cyber Bakugan: Altair. As the boys make their way to her location, Mira is confronted by Lync, who is armed with Altair. During the battle, Mira seems to have the upper hand with Wilda and her trap Baliton. That is until Lync activates two Double Abilities in a row. The scientists are worried about Altair's power fluctuation but Dr. Clay orders Lync to destroy Wilda and Baliton. Before he can, the massive overload causes Altair to crash and shut down, ending the battle. Dr. Clay decides to use the data to perfect Altair into the most powerful Bakugan ever.
