Watta Takeo is a twelve-year-old elementary school student thrust into the presidency of Takeo General Company after his father's sudden death. As the new president, he shoulders dual burdens: managing the company's daily operations and piloting its primary asset, the transforming robot Trider G7, Earth's defense against the alien Robot Empire from Planet Gabarl. He must balance schoolwork with executive duties, including company finances and employee oversight, earning him the internal title "Young President."

His responsibilities demand strategic decisions for both business ventures and combat missions. He deploys Trider G7 for diverse tasks, from rescue operations and cargo transport to repelling invasions by the Robot Empire. Manager Umemaro Kakikōji, mechanic Tetsuo Atsui, and office administrator Ikue Sunabara form his key support team. Operations extend beyond tactics to encompass budgetary constraints, accounting for repair costs and resources expended during extraterrestrial battles.

Character development focuses on Takeo adapting to leadership while navigating childhood. Episodes depict routine challenges like homework, school festivals, meeting payroll, and navigating classmate relationships. A recurring theme is the tension between his desire for normalcy and the weight of his responsibilities. The series concludes with his elementary school graduation, symbolizing a transition towards maturity and acceptance of his dual identity as student and Earth's protector.

His leadership prioritizes protecting others' well-being over corporate profit, evident when he uses loudspeakers to warn civilians before deploying Trider G7 from its concealed playground base. His relationships with company employees reflect a collaborative dynamic built on mutual loyalty. The character's documented appearances are confined to the original television series.
