Solaris emerges as the primary antagonist in the 1994 Gatchaman OVA, succeeding Berg Katse as Galactor's operational leader. Commanding from Galactor's hidden base, Solaris orchestrates attacks to sabotage Earth's energy unification Mantle Plan, deploying destructive mechanized forces such as a dragon-shaped warship decimating cities with plasma beams. Solaris aims to render Earth uninhabitable for humanity using geological disruption devices. During the conflict, Joe the Condor uncovers his potential biological link to Galactor while infiltrating Solaris' headquarters to transmit its coordinates. Solaris captures Joe after he succeeds in sending the location data. Solaris confronts the assaulting Gatchaman team and Red Impulse squadron during their attack on the Galactor base, leading to a decisive battle with heavy casualties on both sides. Ken fatally wounds Solaris in the final confrontation, though Solaris declares this defeat insignificant to Galactor's larger goals before perishing. A post-credits scene confirms the Gatchaman team's survival. Concept art for the canceled Imagi Studios film project depicted Solaris as a male alien overlord lacking shape-shifting abilities, featuring a desiccated appearance and futuristic armor. This version was planned as cold and calculating, including scenes torturing Dr. Nambu, but remained unrealized due to the project's cancellation.
