Aay is a human male antagonist who begins his career working for AAAnimus Inc., wielding a Ventus Bakugan named Mantonoid. He engages in destructive schemes such as terrorizing a mall and attempting to rob a Los Volmos burger joint, but his plans are consistently thwarted by protagonists including Dan Kouzo, Drago, Magnus Black, and Shun Kazami. After repeated failures, AAAnimus Inc. terminates his employment. He then joins the Exit Team, rising to leadership while living with his younger brother Trey. Aay is arrogant, condescending, and rude, demanding obedience from others. During Bakugan: Armored Alliance, he supports Trey in the Bakugan Battle League, having temporarily surrendered Mantonoid due to a post-Tiko incident ban preventing Aay from using his own Bakugan. He mentors Trey in combat strategy to defeat Dan Kouzo, and later reclaims the Bakugan. Aay demonstrates cooking proficiency and a noted disdain for chocolate. Despite his early villainy, he evolves toward more collaborative efforts with the Exit Team, participating in benevolent activities with the group and showing loyalty to his brother.
