Godzilla vs. Mothra (1992)

In 1993, a huge meteor strikes the Earth near the Ogasawara Trench, awakening Godzilla, who was hibernating there. The impact triggers a series of earthquakes and typhoons across the Pacific Ocean, unearthing a gigantic egg on an Indonesian island. Meanwhile, thief and ex-archaeologist Takuya Fujito explores an ancient temple in Thailand, searching for a valuable artifact. Takuya finds the artifact, but triggers the temple to begin collapsing. Takuya barely escapes with his life, but is immediately apprehended by Thai authorities. Takuya is visited in prison by Japanese government secretary Ruzo Dobashi, Marutomo Company employee Kenji Ando, and his ex-wife Masako Tezuka. They inform him that the Marutomo Company is developing an island in Indonesia, with the backing of the Japanese government. Recent satellite scans of the island have revealed a bizarre huge object, which Ando and Masako are being sent to investigate. If Takuya assists them in the expedition, he will be set free from prison. Takuya refuses at first, believing the Japanese consulate will set him free anyway, but quickly changes his mind after learning he may be held in prison for up to 15 years. In Japan, Dobashi informs Environmental Planning Bureau Chief Joji Minamino of the expedition, but Minamino is more concerned about the natural disasters the meteor has been triggering. Minamino and Dobashi meet with Miki Saegusa, who informs them that Godzilla has been roused from his hibernation in the Ogasawara Trench by the meteor, and is at large once again.

After departing from Bangkok via a boat, Takuya, Masako and Ando arrive at the Indonesian island, known as Infant Island. The three come ashore on the island, which is covered in dense jungles and seemingly uninhabited. As they explore, they come upon a section of the island that has been cleared by the Marutomo Company, leading them to remark that man is destroying what nature has taken thousands of years to build. After further exploring, the three come upon a rickety bridge spanning a river. Takuya insists they can all safely make it across, but as they cross the bridge snaps and leaves the three dangling over the river. At Takuya's insistence, they all jump into the river below one-by-one. Takuya then consults the map of the island, and realizes they will reach their destination faster by traveling upriver. After canoeing up the river for several hours, the three set up camp for the night. As they sit by the fire, Masako gives Takuya a letter written to him by their daughter, Midori. Midori is unaware that Takuya is a thief, as Masako doesn't want her to know. The next morning, Takuya finds a large cave near the camp, and wakes both Masako and Ando so they can investigate. Inside the cave, they see several ancient paintings, one of which depicts two huge moths locked in battle. As the sun passes overhead, it shines through a hole in the wall and casts light on a path outside the cave. The three follow it, and come upon the colossal object, which they determine is an egg. As they ponder what could have laid such an egg, they hear two voices say the egg belongs to Mothra. Two miniature twin women emerge from behind a flower and introduce themselves as the Cosmos. They explain that 12,000 years ago, Mothra was the guardian of Earth, which was inhabited by an advanced human civilization. When scientists developed a climate-controlling device, this greatly offended the Earth, which created the black Mothra: Battra. Battra not only destroyed the device, but declared war on all of humanity, believing it to be a threat to the Earth. Mothra battled Battra and defeated him, sealing him in the North Sea, then retreated to Infant Island to live with the Cosmos. The Cosmos express their fear that the recent meteor impact may have awakened Battra, who will no doubt resume his campaign against the human race. Ando contacts his employer, Takeshi Tomokane, and tells him about the egg. Currently experiencing difficulties with his company's developments at Mount Fuji, Tomokane believes the egg will make a fantastic tourist attraction for his company to exploit, so he sends ships to escort the egg back to Japan. The Cosmos allow the egg to be taken to Japan, believing it could be safer in a controlled environment there than exposed on the island.

While the egg is being transported, the larval form of Battra appears off the coast of Japan, rapidly approaching the mainland. The JSDF assaults the beast, but their weapons have no effect, and Battra comes ashore. Battra begins burrowing underground, then surfaces at Nagoya Castle. Battra begins terrorizing the city of Nagoya, blasting apart buildings with beams fired from his eyes and horn. Once Battra reaches Nagoya Tower, he is confronted by numerous tanks and MBT-MB92 Maser Cannons. They too fail to wound Battra, who topples the tower and returns to the ocean, heading toward the Philippines. As the Matrutomo convoy passes the coast of the Philippines, the captain detects a large object approaching their ship. The water begins to boil, and a blue beam shoots into the sky. Godzilla surfaces and begins to approach Mothra's egg. Hoping to save the ship, Takuya attempts to detach the raft carrying the egg from the ship, but Ando attacks him, saying he has to ensure the egg reaches Japan. Takyuya is able to knock Ando down, then pulls the switch to detach the raft. The egg begins to crack, and Mothra hatches from it. Godzilla fires his atomic breath at Mothra, who jumps into the water and hides behind the raft. Mothra swims behind Godzilla and bites down on his tail, but Godzilla flings her away. As Mothra and Godzilla battle, Battra approaches the area. Battra knocks Mothra out of his way, then attacks Godzilla. The two monsters sink to the ocean floor as they fight, while Mothra swims back to Infant Island. As Godzilla and Battra struggle on the ocean floor, the fault between the Philippine and Eurasian plates splits open, expelling magma into the water. Godzilla and Battra are pulled into the fissure, and immediately vanish from all radar. With Godzilla and Battra presumed dead, Masako and Takuya stay at a hotel in Manila, with the Cosmos staying with them. At the hotel bar, Takuya and Masako reminisce about their honeymoon in Cairo, and remember the feelings they once had for each other. The next morning, they find that the Cosmos have disappeared from their room, having been kidnapped by Ando and brought to Tomokane in Tokyo. Tomokane congratulates Ando for his efforts, and declares that the Marutomo Company will use the Cosmos as their next major attraction. The Cosmos sing to Mothra to summon her to their rescue, and she promptly leaves Infant Island and begins swimming to Japan. As Mothra nears Japanese waters, Dobashi and Minamino give the order for the JSDF to try and stop her. The JSDF's weapons fail to halt Mothra's advance, and she nears Tokyo Bay. Masako and Miki Saegusa, accompanied by Midori, try to find the Cosmos in order to prevent Mothra from destroying Tokyo. Using her telepathy, Miki traces the Cosmos to a hotel in central Tokyo, where Takuya has brought them after stealing them from the Marutomo Company, intending to sell them. Masako confronts Takuya, saying she is ashamed of him. Midori implores her father to let the Cosmos go, saying she doesn't want to be a thief's daughter. Takuya lets the Cosmos go, and they stand in a window and communicate with Mothra, telling her they are safe and that she doesn't need to keep tearing apart the city. Mothra acknowledges them and begins crawling away, but the JSDF opens fire on her. This time, Mothra is injured, and begins weakly crawling to the National Diet Building. Mothra begins spraying silk around herself, building a huge cocoon on the Diet Building. As a crowd of spectators looks on, Miki remarks that she can sense Godzilla.

At that moment, Mount Fuji begins erupting violently, and Godzilla emerges from its crater, having swum through miles of molten magma. Godzilla walks down the slopes of the mountain, heading directly for Tokyo. The JSDF deploys a squadron of MBT-MB92s and new ASTOL-MB93 Maser attack aircraft to engage Godzilla, but he easily destroys them with his atomic breath. Meanwhile, Battra appears in the ocean, and transforms into his imago stage. With both Godzilla and Battra approaching the Tokyo area, Mothra emerges from her cocoon in her imago stage, then flies off to destroy Battra once and for all. Mothra flies over the Cosmo World theme park in Yokohama, and is attacked by Battra near the Yokohama Bay Bridge. Battra blasts Mothra's wings with his prism beams, and she crashes to the ground in the Minato Mirai 21 district. Before Battra can finish Mothra, Godzilla enters the area, intent on finishing his battle with Battra. Godzilla clashes with Battra, who topples the Yokohama Landmark Tower onto Godzilla. As Battra flies overhead, Godzilla breaks free and blasts him with his atomic breath, knocking him to the ground. Mothra sees Battra being beaten, then takes flight and lands near him and begins communicating with him. The two monsters put aside their differences, and decide to fight together against Godzilla. Godzilla roars and begins approaching, and Mothra attacks him. Mothra releases scales from her wings that create a 3-D mirror around Godzilla, deflecting his atomic breath. Mothra releases arc lightning from her wings that shocks Godzilla and begins subduing him. Godzilla retaliates with a nuclear pulse, which breaks the 3-D mirror and sends Mothra crashing into the Cosmo Clock 21. Before the huge Ferris wheel can fall and crush Mothra, Battra grabs it and throws it at Godzilla instead. Mothra and Battra then attack Godzilla at the same time, defeating him after Battra fires his prism beams into Mothra's 3-D mirror, striking Godzilla multiple times. Godzilla falls to the ground, and Mothra and Battra grab him to carry him away from Japan. Godzilla bites into Battra's neck, causing him to bleed profusely. As Mothra and Battra carry Godzilla over the open ocean, Godzilla fires his atomic breath into the wound on Battra's neck, killing him. Mothra is forced to release Godzilla, sending him along with Battra's lifeless body plummeting into the sea below. Mothra then places a seal over the ocean, honoring Battra's sacrifice.

The next day, Mothra sits at Haneda Airport, where the Cosmos thank the humans who helped them and bid them farewell. They explain that Battra was destined to destroy a meteor set to strike and destroy the Earth in 1999, and Mothra agreed to take his place in the event of his death. Mothra will fly into deep space and try to change the meteor's course herself. The Cosmos tell humanity to remember the sacrifice Mothra has made for them, then travel with Mothra into outer space.
