Godzilla: Final Wars (ゴジラ ファイナル ウォーズ, Gojira Fainaru Wōzu) is a 2004 kaiju film directed by Ryuhei Kitamura, with special effects by Eiichi Asada. Distributed by Toho and produced by its subsidiary Toho Pictures, it is the 29th film in the Godzilla franchise, and the sixth and final film in the franchise's Millennium era. The film stars Masahiro Matsuoka, Rei Kikukawa, Don Frye, Maki Mizuno, Kazuki Kitamura, Kane Kosugi, Kumi Mizuno, Kenji Sahara, Masami Nagasawa, Chihiro Otsuka, Shigeru Izumiya, Masakatsu Funaki, Masato Ibu, Jun Kunimura, and Akira Takarada, with Tsutomu Kitagawa as Godzilla, Kazuhiro Yoshida as Gigan and Motokuni Nakagawa as Monster X. In the film, when a mysterious race of aliens known as the Xiliens arrive on Earth, the Earth Defense Force (EDF) find themselves locked in battle with various monsters attacking cities around the world, leading them to revive the only chance to save their planet: Godzilla.

The film coincided with the 50th anniversary of the franchise and features a variety of actors and kaiju from previous films. Godzilla: Final Wars premiered on November 29, 2004 in Los Angeles, California, and was released theatrically in Japan on December 4, 2004 to mixed reviews and it underperformed at the box office. Before the world premiere, Godzilla received a star on the Hollywood Walk of Fame.

Afterwards, the franchise went on hiatus for ten years until American studio Legendary Pictures revived the franchise with Godzilla in 2014. Its success prompted Toho to revive the Japanese side of the franchise with Shin Godzilla in 2016, which also proved successful. A series of suitmation short films produced for the Godzilla Fest events (2021-2024) would use replicas of the Godzilla and Hedorah suits from Godzilla: Final Wars.

Over the course of the 20th century, environmental disasters cause the appearance of giant monsters and superhumans, dubbed "mutants", who are then recruited into the Earth Defense Force (EDF) to battle the monsters. The strongest of these monsters is Godzilla, who becomes the EDF's greatest enemy and frequently threatens mankind over the years. In Antarctica, Godzilla is finally imprisoned under the ice during a battle with the powerful EDF warship Gotengo.

Many years later, in 2004, an upgraded Gotengo, now commanded by Captain Douglas Gordon, battles and destroys Manda in the English Channel off the coast of Normandy, but the ship sustains serious damage during the battle and Gordon is suspended from the EDF. Mutant EDF ensign Shinichi Ozaki is tasked with guarding a U.N. biologist, Dr. Miyuki Otonashi, who is sent to study a mummified monster. As they examine it, they are briefly teleported to Infant Island by the Shobijin, who reveal the mummified monster as Gigan, an extraterrestrial cyborg that attempted to destroy the Earth ten thousand years earlier, and was ultimately subdued by Mothra. They warn that a battle between good and evil will happen soon, and that Ozaki must choose a side.

Several giant monsters attack major cities around the world: Rodan attacks New York City, Zilla attacks Sydney, Anguirus attacks Shanghai, King Caesar attacks Okinawa, Kamacuras attacks Paris, Kumonga attacks Monument Valley in Arizona, and Ebirah attacks Tokai. Meanwhile, Minilla, Godzilla's son, is found in Aokigahara by Kenta Taguchi and his grandfather, Samon. The EDF engages the monsters until they mysteriously vanish, as a huge alien vessel appears over Tokyo. The aliens introduce themselves as the Xiliens, claim that they eliminated the monsters as a gesture of goodwill, and warn Earth's leaders that an incoming runaway white dwarf star called Gorath will soon impact the Earth, offering their help to destroy it.

After a peace pact is signed between humanity and the Xiliens, Ozaki, Miyuki, and Miyuki's sister Anna, a news reporter, discover that the Gorath shown by the Xiliens is a hologram and that the Xiliens have replaced several members of the EDF and U.N. secretary-general Naotaro Daigo with imposters. After the Xiliens are exposed with help from Gordon and the other mutants, the Xiliens' second-in-command, the Controller, kills his leader to assume command, revealing their plan to use humans as a food source while taking control of all the mutants, except for Ozaki, through a property in their DNA known as "M-base". The Controller also has the monsters under his control through M-base in their DNA, and awakens Gigan to wipe out the EDF. The group escapes in a repaired Gotengo, although Gigan pursues them.

Gordon convinces the Gotengo's crew to travel to Antarctica to release Godzilla, who is immune to the Xiliens' control thanks to his lack of M-base and easily defeats Gigan. The Gotengo then guides Godzilla into a series of battles with the other monsters: he defeats Zilla in Sydney, Kumonga in New Guinea, and Kamacuras in Manazuru. At Hakone, Samon, who witnesses Godzilla’s arrival with Kenta and Minilla, remarks that long ago, humanity’s actions angered Godzilla, leading to his decades of aggression. After Godzilla battles and subdues Rodan, Anguirus and Caesar at Mount Fuji, the Gotengo leads him to Tokyo to defeat the Xiliens.
