SSS9 is the main antagonist of Godzilla vs Biollante. He was a spy and assassin.
He was portrayed by Brien Uhl.
SSS9 was sent to retrieve samples of Godzilla's cells from the ruins of Tokyo in 1984. He did so by waiting for a trio of Bio-Major agents to get the cells for him, then he ambushed them and killed them, stealing the cell samples and taking them back to his homeland, Saradia. Five years later, SSS9 was sent to Japan to steal the Anti-Nuclear Energy Bacteria for Saradia's own purposes. This again brought him into conflict with Bio-Major, specifically its agents Michael Low and John Lee, the latter of whom SSS9 would ultimately kill. He succeeded in stealing the ANEB after killing Lee.
Later, though, after Major Sho Kuroki and Lieutenant Goro Gondo stole back the ANEB from one of Saradia's Japanese offices, SSS9 was told by his superior, Abdul Zaruman, to assassinate Dr. Genshiro Shiragami so that Japan could never make any more ANEB, in the hopes that Godzilla may eventually return and destroy Japan, undaunted by the humans' inventions. SSS9 waited until after the Self-Defense Forces had used the ANEB, in combination with heating pads, to seemingly kill Godzilla, before he shot and killed Dr. Shiragami. He then attempted to escape in his car but was pursued by Kazuhito Kirishima who forced him off the road. SSS9, unknowingly standing on one of the gargantuan heating pads, prepared to shoot Kazuhito only to be killed when Major Kuroki activated the pad, incinerating the killer.
