After the battle with Lync and Volt, Dan, Drago, and Marucho go with Mira to the Resistance base. Along the way, Mira reveals that only a few people of the Vestals realize that the Bakugan are intelligent creatures, while the rest of the people have not been told. She reveals that after discovering this for herself, and becoming outraged with her father for participating in the capturing of the Bakugan, she ran off and created the Bakugan Brawlers Resistance, joining with people who thought as she did. Upon arriving at the base, they meet Baron, a major fan of the Bakugan Battle Brawlers and the 6 hero bakugan. Shortly after, another Resistance Brawler named Ace, highly disapproves of Mira bringing humans to aid in their quest to free the Bakugan. Instead, he challenges Dan to a battle, and says that if he beats him, he and Marucho can join the Resistance in their quest to save the Bakugan. Dan gets off to a rocky start, but he and Ace are too evenly matched. With one win and one loss for each their battle ends in a tie and they become fast friends.
