Mā is the central protagonist, discovered as an infant inside a rescue pod that crash-landed on Planet M7.8. His origins remain shrouded in mystery, with no knowledge of his parents or their fate after their mothership vanished, igniting his personal quest.

Raised within Planet M7.8's boarding environment alongside other children of Ultra beings and monsters, he integrates well despite his unknown lineage. As graduation nears, his peers collectively construct a spaceship specifically for his journey across the cosmos to find his biological parents.

His personality blends natural leadership with playful curiosity and a streak of mischief, defining his role within the group. He exhibits growing mastery of inherited Ultra Powers, though their control remains imperfect; his attempts to deploy an Ultra Beam often result in wild or unintended discharges, reflecting his ongoing development.

Throughout the journey, he forms vital bonds with companions like Piko and Bal, relying on teamwork during their adventures. Key events showcase his courage and determination: battling foes like King Docking to free enslaved travelers, seeking guidance from Fortune Teller Ura who knows of his parents, and navigating encounters with figures like Ms. Pent, entrusted with his care during his parents' absence due to a Nebula Hurricane.

His character arc remains intrinsically linked to resolving the search for his parents, driving both his actions and the series' overarching narrative.
