Gatchaman Unmasked
The ISO and the UN have developed a special radar to search for the main beam cannon. But Galactor learns about this, and during one of their attacks, Chief Anderson is badly hurt. Gel Sadra wants to reveal the true face of Gatchaman. Since she doesn't know what he looks like, she starts attacking one employee of the ISO after the other. Ken feels sorry about all the victims. Meanwhile Sam, the grandson of Chief Anderson, is captured. In order to avenge his grandfather, he pretends to be Gatchaman and is tortured mercilessly. Ken has secretly sneaked into the base as a Galactor member. However, Gel Sadra notices the unknown trooper and has him unmasked, thus revealing his true identity. Ken goes into bird style, rescues Sam and charges at Gel Sadra. She flees, leaving behind the menacing words "Stupid Gatchaman! I have now seen your true face, the next time I will win for sure!" The enemy base becomes the Mecha Sentango and starts creating havoc. The two men escape from the ammunition depot and are picked up by the New God Phoenix. Through an attack by the Eagle Sharp, Sentango explodes. But the enemy now knows that Ken is a member of the Science Ninja Team. Will there be a tomorrow for him?

Eagle Riders
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.
