Americanized Godzilla

When American reporter Steve Martin investigates a series of mysterious disasters off the coast of Japan, he comes face to face with an ancient creature so powerful and so terrifying, it can reduce Tokyo to a smoldering graveyard. Nuclear weapon testing resurrected this relic from the Jurassic age, and now it's rampaging across Japan. At night, Godzilla wades through Tokyo leaving death and destruction in his wake, disappearing into Tokyo Bay when his rage subsides. Coventional weapons are useless against him; but renowned scientist Dr. Serizawa has discovered a weapon that could destroy all life in the bay -- including Godzilla. But which disaster is worse, Godzilla's fury, or the death of Tokyo Bay?

The heavily re-edited American version of Godzilla Raids Again. A prehistoric monster called Gigantis emerges alongside another creature named Angurus.

(Re-edited US Version) Eric Carter, a reporter for the United Nations, reports on a submarine which collides with an iceberg and frees Godzilla. The news of this soon leads to Mr. Tako, the chairman of a pharmaceutical company, to seek a monster of his own to generate publicity. He sends out an expedition to Farou Island where they discover the god of the island in the form of King Kong. The giant ape is capture and returned to Japan, upon which it escapes and heads off on a collision course straight towards Godzilla. The two rivals soon clash in a giant climatic battle.

A reporter investigates the disappearance of a ship. He finds the ship and discovers that all the hands have been killed by a giant sea louse except for one. The lone survivor then tells the reporter that the ship was attacked by Godzilla (Gojira). Fearing a panic, the Japanese government then takes the survivor into custody to keep him from revealing that Godzilla has returned. However, a Soviet nuclear submarine is destroyed and the situation puts them and the United States on the brink of nuclear war, until the Japanese decide to come clean and admit that it was Godzilla. Soon the Japan and the rest of the world are on red alert as they wait for Godzilla to begin his rampage anew.
