Gatchaman II

Peace has been restored to Earth... but not for long. After two short years, Sosai X announces his return by crashing into and sinking the cruise ship Queen Margaret; kidnapping one of the survivors--a four-year-old girl named Sammie Pandora, and force-growing her into GelSadora, the next general of Gallactor. The Syndicate restores its forces and begins capturing military and scientific experts, leaving the ISO no recourse but to revive its own first line of defense: the Kagaku Ninjatai.

But with Condor Joe missing and presumed dead, things aren't quite the same, and even with new weapons and vehicles, the team is at a loss. Dr. Nambu compounds the problem by bringing in a new G-2, Getz the Hawk.
