Gamera (Showa)

A nuclear explosion in the far north unleashes Gamera, the legendary flying turtle, from his sleep under the ice. In his search for energy, Gamera wreaks havoc over the entire world, and it's up to the scientists, assisted by a young boy with a strange sympathetic link to the monster, to put a stop to Gamera's rampage.

After a treacherous expedition to retrieve a giant opal, disaster strikes as the opal reveals itself to be an egg which spawns Barugon, demon dog from Hell! Armed with a deadly tongue and cold beams, Barugon wreaks havoc on Japan. Gamera comes to save the day.

Three children, two boys and a girl, stumble upon a flying saucer. The boys both step in without hesitating, and are whisked away to a planet in Earth's orbit but on the exact opposite side of the Sun. Inhabiting this planet are two women with Midwestern accents, who hypnotize the children to find they fantasize about milk, donuts, and Gamera, our favorite hero turtle. The women simply want to eat their brains. Back home, no one will believe the little girl's story of alien abduction, not even Officer Concha (pronounced "Cornjob"). Finally, Gamera rescues the children while fighting Guiron, a monster with a giant knife for a nose. Gamera kills Guiron while doing gymnastics on a parallel bar and takes the kids home, where the kids hope for peace, understanding, and the end of traffic accidents.

A pair of earthquakes, in the Myojin Reef and on Myaki Island, lead to Mt. Fuji waking from dormancy. Fuji's eruption, in turn, draws a visit from Gamera. When a party of researchers is sent to Fuji to investigate, a glowing green pit on Mt. Futago sends some yellow beams that slice the craft in two. All are lost. A reporter heads toward the site and talks the boy Eiichi into leading him toward the green glow. The glow is from a giant winged creature called Gyaos who has been wakened from a long slumber by the earthquakes. It begins to hunt warm-blooded prey, including the reporter who flees a cave that little Eiichi has explored with him. Just as Gyaos is about to kill Eiichi, Gamera steps in to help rescue him. In getting the boy free, he himself suffers a deep gash on his right front leg. He goes off to heal on the bottom of the sea while the Japanese science and military community search for a way to kill Gyaos. A squad of jets is sliced and diced as they bomb the area around the pit where Gyaos is hiding. Eiichi points out that Gyaos only hunts at night. The next attempt is to position a fleet of tanks to shoot at it when it emerges from the pit. Gyaos seems immune to the shelling. It uses powerful flapping of its wings to toss the tanks about. In the end, it is Eiichi, who has a friendship link to Gamera, that suggests a forest fire will weaken Gyaos and let Gamera prevail. Gamera is finally able to get the upper hand, and drags Gyaos to its death in the crater atop Mt. Fuji.

A giant creature attacks Japan during the World Fair and its up to Gamera to stop it. But the monster injects Gamera with its offspring and a research team must take a craft into Gamera's body to eliminate the parasite.

A moon base is destroyed by a spaceship with a cluster of gumballs on its head. Later, at Sea World, dolphins are dying mysteriously. Zigra kidnaps two men and two children (one of whom is a Coke addict - Coca-Cola that is) and starts causing earthquakes. The two six year olds somehow outwit Zigra and help their incapacitated fathers escape. The Zigra Woman, who can use her eyes to put people into comas, then chases them all over Sea World like an extended Benny Hill skit. Somewhere in this movie Gamera finally shows up, fights Zigra, who turns into a giant swordfish.

Using several clips from previous Gamera entries, this film deals with alien forces sending all the monsters Gamera has faced in one final battle to rid the planet of its last hope.

A group of aliens from another planet head for Earth with the intentions of conquering it. Their first ship is destroyed in transit by the giant flying turtle Gamera. A second ship makes it to Earth and captures two Boy Scouts and holds them captive so that Gamera will not attack them. The aliens then implant a remote control device into the monster's neck and use the great turtle to attack Tokyo. The boys then come up with a plan to foul up the remote control device to the point where Gamera does the opposite of what he is ordered to. As a result Gamera destroys the aliens ship, but then has to contend with their giant squid like leader Viras.
