Tsukioka and Kobayashi report to the authorities in Osaka, and find out that the other monster Godzilla was fighting is Anguirus. A group of scientists with the two pilots research Anguirus in a book written by a Polish scientist. The Godzilla and Anguirus lived around the same time millions of years ago. The Anguirus hated hostile creatures, which explains the intense rivalry between the two monsters.
Dr. Yamane, who experienced Godzilla's first attack, was also present at the meeting, and shows a film of the Godzilla attacking Tokyo just one year before. He then explains that the Godzilla Tsukioka and Kobayashi saw is the same Godzilla as the one from the year before. Yamane states that there is no way to kill Godzilla, and that Dr. Serizawa, the inventor of the Oxygen Destroyer, had died and burned the formula. Yamane, though, suggests that the military should use flares on Godzilla to attract the monster away from the shore. Godzilla becomes angry when he sees lights because the hydrogen bomb's bright explosion had awakened and mutated him.
One day unexpectedly, Godzilla shows up on the shore of Osaka. Jets are sent to shoot flares from their planes to lead Godzilla away from the shore. Godzilla sees the flames, and, as Yamane predicted, starts to walk away.
Meanwhile, a prison truck transports dangerous criminals to another part of the country. All of the criminals, using body language, decided that this would be a great opportunity to escape from prison. The prisoners beat up the two policemen guarding the back door of the truck, and run away. A few of them use a gasoline truck. The truck crashes into an industrial building and starts a massive fire.
The fire attracts Godzilla to the shore of Osaka again. A few minutes later, Anguirus swims to shore and attacks Godzilla. The two monsters fight an intense battle, while destroying several buildings, including the tuna cannery that Tsukioka and Kobayashi work for. Godzilla finally bites Anguirus's neck, and throws him on a moat near Osaka Castle. Godzilla then fires his atomic breath and burns Anguirus to death.
Tsukioka and Kobayashi are transferred to a Hokkaido plant. During a company party, Tsukioka and Kobayashi are notified that Godzilla destroyed one of the company fishing boats. The military, and Tsukioka begin a massive search for Godzilla. Tsukioka spots Godzilla swimming to the shore of a small, icy island. He notifies the cannery, and Kobayashi takes off in his plane to switch shifts with Tsukioka.
Kobayashi dives his plane towards Godzilla to distract him from walking back into the ocean. Tsukioka then transferred to the air force, travels on a jet with an old college friend. They drop bombs on Godzilla but are unsuccessful. Godzilla then wades towards shore. Koboyashi dives towards Godzilla again but Godzilla fires his atomic breath at Kobayashi's plane. The plane then crashes on an icy mountain, killing Kobayashi.
Tsukioka grieves but then notices that the military can shoot missiles at the mountain, and bury Godzilla in an avalanche. The jets fire the missiles, and bury Godzilla in snow to his waist.
The jets return to base to reload, and Tsukioka is authorized to fly in his own jet. The jets return to the icy island, and shoot missiles at the mountain, burying Godzilla to his neck. Tsukioka then shoots his missiles burying Godzilla completely. Tsukioka looks to the sky, and says, "Kobayashi, we have finally defeated Godzilla."
The film sold approximately 8,340,000 tickets in Japan. It is the third most-attended Godzilla film in Japan, even though the film was poorly received by fans and critics, and Godzilla would not re-appear until 1962 in King Kong vs. Godzilla.
Instead of merely re-dubbing the film, Henry Rybnick and Edward Barrison planned on a radically altered version to be called The Volcano Monsters which was planned for a 1957 release. All scenes with Japanese actors would be cut, saving just special effects scenes, and these would be altered to reduce the apparent size of the monsters to a more dinosaur like scale. In addition, all scenes with Godzilla breathing fire were to be cut. A totally new script was written by SF screenwriter Ib Melchior, to be shot with American actors. New special effects footage was to be shot as well, and to that end Toho sent the suits for Godzilla and Anguirus to the United States. Ultimately, the modified film was never produced, and the monster suits disappeared.
Instead, in 1959 Warner Brothers theatrically released a heavily edited version of Godzilla Raids Again, under the title Gigantis the Fire Monster. For a long time, this change in name was thought to be because Warner did not have the rights to "Godzilla". However, Edward L. Schreibman, the producer of the American version, has said that he changed Godzilla's name to "Gigantis" to give the audience the impression that they were seeing a new monster.
George Takei, better known as Lt. Hikaru Sulu in the original Star Trek series, was one of the many voice actors employed for this film. The only other Kaiju film he performed voice work for was in the movie, "Rodan."
Various Edits and Changes:
Oddly enough, the Disney channel showed the version with the altered title card during the early 1990s. Before that, all broadcast versions sported the "Gigantis The Fire Monster" title card.
One edit is blocking the Hindu swastika to not be confused with Nazism.
