Zedus attacks again, and a newly revitalized Toto flies out to battle him. In order to combat this new menace, they hook Toto up to a machine which feeds him a liquid version of the strange red stone that Toru had found the egg laying on, which scientists theorize gives Gameras their power. Toto gets pummeled in his first battle, falling victim to Zedus' long, piercing tongue and the government shortly arrives to capture and investigate him. Sporting tusks, Toto is ready for battle. Out of no where, Toto appears and is much larger. Zedus eats several people trying to run away.

Heavy stomping is heard, and soon the dinosaur-like monster Zedus appears. As Toru is sulking over the loss with his friends, tornado sirens begin blaring. No one knows what is happening, or what is causing the disasters. Meanwhile, off the coast of Iseshima, many bizarre shipping disasters have been occurring.

When he picks up the egg, a baby turtle hatches. Toru finds an egg lying on top of a strange red rock with patterns carved into it. When playing on the beach with his friends, he sees a strange red glow emanating from a nearby rock formation. Toru's mother has recently died in a car crash, and this is his first summer without her. Thirty three years later, the little boy has grown up and owns a small restaurant in the Japanese coastal town of Iseshima. In 1973, Gamera self-destructed to kill a flock of Gyaos, which were attacking a small village.
