Aay, a human male and secondary antagonist affiliated with AAAnimus Inc., relentlessly pursues the capture of Bakugan owned by the Awesome Brawlers. Repeated failures result in his dismissal, prompting him to join the Exit Team, where he ascends to leadership while residing alongside his younger brother, Trey.

His Ventus-attribute partner Bakugan, Mantonoid, is temporarily transferred to Trey during *Armored Alliance* before Aay reclaims it under unclear circumstances in *Geogan Rising*.

Early antagonism sees Aay orchestrating a mall disturbance to aid Magnus Black’s infiltration of the Awesome Ones—a plan foiled by Magnus and Shun Kazami. He later confronts Dan Kouzo in a Bakugan battle during a botched robbery at a Los Volmos burger establishment, suffering defeat.

Though marked by arrogance, condescension, and a domineering attitude toward allies and bystanders alike, Aay evolves from villainy to collaborative efforts with the Exit Team. Beyond combat, he exhibits culinary skill and a noted disdain for chocolate. His loyalty to Trey surfaces through support in Bakugan Battle League matches, underscoring a familial bond that shapes his later choices.
