Adad is an Alien Scruda agent serving as Agent Adad of the Immigration Administration Bureau under the Star Cluster Council. Dispatched to Earth to locate the lost genius Yapool and monitor the entity Bemular, he operates with autonomy but faces distrust from his superiors due to his unorthodox methods and defiance of orders. He stands approximately 1.94 meters tall and weighs around 107 kilograms, and at the time of the story he is 271 years old. Adad speaks in an eloquent and theatrical manner that masks a cruel and mocking personality. His first public appearance occurs at a concert, where he threatens the audience to draw out Ultraman Suit users. The confrontation is revealed to be a ruse: Adad uses floating devices to expose human crimes involving a series of murders and the framing of alien refugees, then executes the perpetrator on stage and teleports away. Later, he defects from the Council to harbor alien refugees in Hong Kong, condemning its corruption. Branded a traitor, he is hunted by assassins. Using performance-enhancing drugs that amplify his strength, size, and regeneration, he fights alongside former adversaries against a bioweapon sent to eliminate him. As a rogue agent, he becomes a freelance protector for alien immigrants, combating human xenophobia. Adad’s story concludes in Detroit while he mediates between human mobs and alien immigrants; an unidentified assailant fatally shoots him. His death inspires human children to honor him and galvanizes his allies to reaffirm their faith in humanity. In combat, Adad possesses superhuman strength rivaling Ultraman Suit users, acrobatic agility, and resilience against extreme gravitational forces. He wields a retractable combat staff effective against energy weapons and a combat knife. He can teleport and has undergone genetic manipulation to enhance his physical capabilities.
