Jet Jaguar (ジェットジャガー,   Jettojagā?) is a heroic mecha created by Toho that first appeared in the 1973 Godzilla film, Godzilla vs. Megalon.


Red Alone Original Concept 2

Jet Jaguar was the result of a contest Toho had in mid-to-late 1972 for fans to come up with a new hero for them to use, to capitalize on the many tokusatsu, anime superhero and super robot shows that were very popular at the time. The winner of the contest submitted the drawing of a robot called Red Alone (レッド·アローン,   Reddo Arōn?). The robot resembled both Ultraman and Mazinger Z (both of which were very popular). The robot's design was altered and it was renamed "Jet Jaguar" and was set to star in its own film, titled Jet Jaguar vs. Megalon, which pit him against Megalon. However, Toho figured Jet Jaguar would not be able to carry the film on his own, in screen appearance or marketing value, so during pre-production, the project was shut down for several weeks, until screenwriter Shinichi Sekizawa was called in to rewrite the script to add Godzilla and Gigan. The resulting film, Godzilla vs. Megalon, paired Godzilla with Jet Jaguar against both Megalon and Gigan.


In Godzilla vs. Megalon, Jet Jaguar was created by scientist Goro Ibuki.


Jet Jaguar friendly
It is revealed that Jet Jaguar gained sentience and is capable of altering his programing in Godzilla Unleashed. Jet Jaguar fights to protect others, and acts very much like a superhero. When not fighting, he is shown to be very friendly towards others, offering handshakes, and even carrying a child on his shoulders.


Showa Series

Godzilla vs. Megalon

Jet Jaguar was a human-sized robot created by inventor Goro Ibuki for unknown reasons. Having been stolen by the underground nation of Seatopia, Jet Jaguar's mission was to guide Megalon to Tokyo so the insect kaiju could destroy it. Eventually, however, Goro regained control of Jet Jaguar and sent him to fetch Godzilla from Monster Island. As Godzilla made his way to Japan, Jet Jaguar flew back to the mainland and faced Megalon. Increasing his size to fifty meters, Jet Jaguar attacked Megalon and was winning the battle until the cyborg Gigan arrived to provide Megalon some back-up. The two evil beasts were too much for Jet Jaguar, who was beaten senseless until Godzilla arrived. After a long fight, Godzilla and Jet Jaguar were able to defeat their foes, sending Megalon back to Seatopia and Gigan back into outer space. After the fight, Jet Jaguar reverted to his normal size, and returned to his home with Goro.

Godzilla Island

Jet Jaguar in Godzilla Island

Jet Jaguar appeared extensively in the TV series Godzilla Island. In the show, Jet Jaguar appears in several different forms: a Silver Jet Jaguar, who was a fighting machine that battled alongside MechaGodzilla and Moguera, a Medic Jet Jaguar, who tended to the injured monsters, and a Fire Fighter Jet Jaguar, who worked to put out the fires caused by the monsters' fights.

The mechanical hero has the ability to alter his size at will, and is skilled at melee attacks. His abilities also include being able to communicate with monsters and flying. He also has floodlights located within his eyes. He is also able to carry incredibly heavy objects and even fly whilst being weighed down by Godzilla riding on his back.

Outside of his film appearances he can fire beams from his arms, similarly to Ultraman. He has also been shown growing larger than his film appearance in the Atari trilogy, rivaling Biollante's height, but being this size makes him very slow.

In Godzilla: Rulers of Earth, Jet Jaguar's intelligence and resilience are emphasized greatly. He is able to control Kiryu like a human pilot, and is able to defend against attacks that would normally critically damage or destroy the other mechs. He is also shown to be able to knock Godzilla out with a single blow to the face, despite being struck at point blank range by Godzilla's atomic breath.


Video Game Appearances

Godzilla: Trading Battle

In Godzilla: Trading Battle Jet Jaguar can release an "explosion breath" from his mouth.

Godzilla: Save the Earth

Jet Jaguar has also appeared in the video game Godzilla: Save the Earth and Godzilla: Unleashed, where he can increase his size further to 1.5 times normal kaiju size.

Godzilla: Unleashed

In Godzilla: Unleashed, he can release a concentrated blast of energy from his wrists, and from the game's predecessor, Jet Jaguar can spin himself around at extreme speeds, creating a deadly tornado; and while in his smallest combat form, Jet Jaguar has a Reflection Shield put up at all times, meaning that he can't be harmed by weapons, and can even perform a Weapon Reflect, in which he can block a weapon to bounce it back at its source.

Height: 90 meters
Weight: 38,000 tons

"Jet Jaguar is a human-sized robot created by a Japanese scientist for unknown reasons. Created with a great potential for learning, Jet Jaguar achieved sentience and began to modify himself and his programming. His most impressive modification has been his ability to change his own size-allowing him to grow large enough to dwarf monsters such as Godzilla. Unfortunately, Jet Jaguar cannot maintain his enormous size indefinitely, and must periodically rest to regain his energies. Jet Jaguar is a reserve member of the Global Defense Force-heroically protecting humanity whenever it is threatened by monstrous threats."

Godzilla: The Game

Jet-Jaguar, the Electronic Robot

Kaiju Guide Jet Jaguar

This remote-controlled robot was developed by the young scientist Goro Ibuki to support humans with their everyday tasks.

This, the first giant robot hero in the series, was based on "Red Alone", the winning entry in Toho's official monster design contest. However, the entry design did not have a robot face, and it also had wings on its back.

"Godzilla vs. Megalon"


Jet Jaguar appears in Godzilla: Rulers of Earth. Jet Jaguar appeared to help Godzilla to fight against Orga and Gigan. After flying into Orga's mouth and expanding in him, causing Orga to explode. When Godzilla inspected Jet Jaguar, he tried blasting Jet Jaguar with his atomic breath, but managed to make Godzilla to turn his attention on Gigan. While Godzilla was distracted, Jet Jaguar noticed that Orga was trying to regenerate his entire body and so he set out to stop the kaiju, but ultimately failed. After Godzilla defeated Gigan, he becomes enraged and attacked Jet Jaguar by firing his atomic breath at point blank range and smacked the robot with his tail, but was knocked out after Jet Jaguar punched Godzilla's face. Eventually, Jet Jaguar flew to the Cryog ship to help Steven Woods and Chavez, but not before throwing Godzilla out to sea.

In Godzilla: Rulers of Earth #12, Jet Jaguar fought Destoroyah, even shrinking to human size, then piloting Kiryu to fire the Absolute Zero Cannon, killing Destoroyah. He then attempted to stop the humans from setting off underwater explosives while Godzilla was in the area, but did not make it in time.

Jet Jaguar then disappeared for several years, but reemerged when the Trilopods attacked the Earth. Jet Jaguar traveled to Los Angeles to assist Godzilla in the battle against the creatures and fought against a Trilopod that had taken on Godzilla's characteristics, but was nearly destroyed by it. Thankfully, Jet Jaguar was saved by Zilla, and joined with Godzilla and his allies to defeat the Trilopods. At some point in the battle, Jet Jaguar managed to attack Gigan and defeat the cyborg monster. After Godzilla destroyed Magita, Jet Jaguar observed Godzilla and the other monsters traveling out to sea, following them from a distance. Jet Jaguar was last seen human-sized being repaired in Dr. Ando's office.

  • For the German release of Godzilla vs. Megalon, Jet Jaguar was renamed to King Kong. However, there is no connection to the real King Kong beyond his name, and in contrary to a widespread misconception, he is not said to be a giant ape wearing a robot suit in the dub.
  • It was suggested that Jet Jaguar and other monsters Godzilla fought were created by Dr. Frankenstein in the German dub of Godzilla vs. Megalon.
  • The anime series Neon Genesis Evangelion paid homage to Jet Jaguar in the episode "A Human Work"; the episode featured a robot named "Jet Alone", a combination of his final and prototype names.  Jet Alone also shares a similar color scheme with Jet Jaguar.
