**Adad** is an Alien Scruda agent from the *Ultraman* series, originally serving the Star Cluster Council under the title Agent Adad of the Immigration Administration Bureau. Dispatched to Earth on critical missions—tracking the lost genius Yapool and monitoring the entity Bemular—he operated with autonomy yet faced superiors' distrust over his unorthodox methods and defiance of orders.
His first public appearance occurred at a Rena Sayama concert, where he staged a confrontation by breaking a man’s neck and threatening the audience. This drew Ultraman Suit-wielders Shinjiro Hayata and Dan Moroboshi into battle, interrupted by Bemular. The incident was a ruse: Adad deployed projection mines to expose human crimes, including manipulating the alien Pigmon (last survivor of Planet Igaru) for murders and framing refugees. After executing Pigmon onstage, he teleported away under Council protection.
Adad later defected from the Council for harboring alien refugees in Hong Kong, condemning its corruption. Branded a traitor, he was hunted by assassins the Leo Brothers. During their clash, Adad used performance-enhancing drugs to briefly match their strength but was overwhelmed until Moroboshi intervened. The Council escalated by deploying the bioweapon Nova to eliminate witnesses, but Adad, Moroboshi, Shinjiro, and the Leos united to destroy it.
As a rogue agent, Adad became a freelance protector for alien immigrants, combating human xenophobia while allying with Red, Yapool, and Bemular. His commitment solidified during a battle against three Ultraman impostors orchestrated by his former superior Mephisto. Adad and Bemular rescued hostages, aided captured Ultras, and helped defeat the impostors, exposing the secret organization Zetton Core under Supreme Chancellor Edo.
Adad’s story concluded in Detroit during mediation between human mobs and alien immigrants. An unidentified assailant fatally shot him mid-negotiation. His death inspired human children to build memorials and galvanized allies like Jack and Taro to reaffirm faith in humanity. Dan Moroboshi posthumously honored him as a "comrade," demanding justice from his killer.
Physically, Adad stands 1.94 meters tall and weighs 107 kilograms. His abilities include superhuman strength rivaling Moroboshi’s Ultraman Suit, acrobatic agility, and resilience against extreme gravity. He wields a combat staff that counters Spacium weaponry and a knife. Genetic manipulation compensated for his species’ physical limitations, making him its first successful subject. He employs drugs to amplify strength, increase size, and accelerate regeneration.
Trivia notes: His name reverses "Dada," honoring the original Alien Dada. At 271 years old during events, he aligns with lore’s Dada Agent #271. He speaks eloquently but displays a cruel, mocking demeanor.
