After the appearance of a new Gojira (Godzilla), the Japanese government builds a robotic Godzilla from the bones of the original monster that attacked Tokyo in 1954 to stop the beast.

The aftermath of the Oxygen Destroyer brings forth Destoroyah, a beast intent on killing Godzilla, who is on the verge of a nuclear meltdown.

When Mothra went into outer space to stop a meteor from reaching Earth, she accidentally took with cells from Godzilla and remaining cells from Biollante that inhabited our atmosphere. The combined cells went through a black hole and created a new creature, Space Godzilla. Space Godzilla heads to Earth to confront Godzilla, Junior Godzilla, and the new G-Force robot, MOGERA.

The United Nations assembles the ultimate weapon to defeat Godzilla, while scientists discover a fresh pteranodon egg on a remote Japanese island.

Time travelers from the 23rd century return to 1992 to warn Japan that Godzilla will cause a catastrophic nuclear incident in the 21st century and suggest a way to rid the world of him forever. They intend to go back to 1944, to Ragos Island, where a dinosaur was exposed to radiation from the Bikini H-Bomb test and became Godzilla. Upon completion of this task, King Gidorâ appears in 1992 and the visitors’ true plan is discovered. They wish to destroy Japan so it will not become the dominant economic force. Luckily for the Japanese, Godzilla was still created and will now fight Gidorâ.

Dr. Shiragami combines the DNA of roses with some extracted from Godzilla’s cells. He names his creation “Biollante”.
