The Return of Godzilla is a 1984 daikaiju film.thumb|300px|right
A Japanese fishing vessel is trying to find its way to shore in a horrible storm while near an uninhabited island, when a giant monster appears and attacks the boat. A few days later, reporter Goro Maki finds the vessel intact but deserted as he explores the vessel, he finds all the crew dead except for one young man called Hiroshi Okumura, who has been badly wounded. Suddenly a giant sea louse attacks but is eventually killed with some difficulty.
In Tokyo, Okumura realizes by looking at pictures that the monster he saw was Godzilla. However the news of Godzilla's return is kept secret to avoid panic until Godzilla attacks a second time and destroys a Soviet submarine. However, the Russians believe the attack was orchestrated by the Americans, and a diplomatic crisis ensues which threatens to escalate into war. The Japanese intervene and finally announce that Godzilla was behind the attack. The Japanese arrange a meeting with the Russian and American ambassadors and, after some debate over the issue, Prime Minister Mitamura decides nuclear weapons will not be used on Godzilla even if he were to attack the Japanese mainland, an announcement that the Russians can't come to terms with. The Japaniese self defense forces are put on alert and search for Godzilla.
Soon, Godzilla appears on an island off the coast of Japan, determined to feed off a nuclear power plant there. When Godzilla attacks the facility and feeds off the reactor, he is distracted by a flock of birds, and leaves the facility almost as quickly as he arrived. Okumura and his friends realize that Godzilla reacts to the same signal as birds, and Professor Hayashida decides to use this method to lure Godzilla away from Tokyo. Meanwhile, the Russians have their own plans to counter the threat posed by Godzilla, and a Russian control ship disguised as a freighter in Tokyo Harbor prepares to launch a nuclear missile from one of their orbiting satellites should Godzilla attack.
Godzilla is later sighted at Tokyo Bay, forcing mass evacuations out of the city and a state of emergency is declared. The JASDF attacks Godzilla with Mitsubishi F-1 fighter jets, but their missiles are useless against him. Godzilla then proceeds to the coast, where the waiting army, equipped with tanks, rocket launchers and soldiers armed with Howa Type 64 assault rifles, proceeds to fire on Godzilla, but they are quickly subdued. Meanwhile, one of the crewmembers aboard the damaged Russian vessel activates the missile (or tries to deactivate it, depending on the film version), which is set for a countdown, before succumbing to his injuries. Godzilla then proceeds towards Tokyo's business district, wreaking havoc along the way. There, he is confronted by 2 laser-armed trucks, and then the Super X, a piloted VTOL craft constructed in secret to defend Tokyo in case of emergency, in particular a nuclear attack.
Godzilla has an allergic reaction to the Cadmium shells that are fired into his mouth by the Super X, and falls down unconscious. Unfortunately, the city is faced with a greater threat when the countdown ends and the Russian missile is launched from the satellite, leaving the Japanese government and people helpless to stop it. However, the Americans intervene and shoot down the missile with one of theirs before it can hit Tokyo. Unfortunately, the atmospheric nuclear blast creates an electrical storm, which revives Godzilla once more.
Godzilla has a final battle with the Super X, eventually damaging the aircraft and forcing it to make an emergency landing where he destroys it by toppling a building on it. Godzilla continues his rampage, until Professor Hayashida is successful with his invention and uses the bird call device to distract him. Godzilla leaves Tokyo and swims across the Japanese sea to volcanic Mt. Mihara, where he notices the signal device which fascinates him. As he walks towards it, he falls into the mouth of a volcano where he is surrounded by detonators, which are detonated when Okumura pushes a red button, thus creating a controlled volcanic eruption that traps Godzilla.
Everyone watches and takes one last look at Godzilla as the ground beneath him crumbles and he falls into the lava, trapping him for good.
