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.

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.


Jet Jaguar doesn't possess a roar, but instead, unleashes a bunch of mechanical or electronic sounds during his screentime.

It is revealed that Jet Jaguar gained sentience and is capable of altering his programming 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.


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


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.

Flight speed

The 2014 Godzilla video game states that Jet Jaguar can fly at mach 3.5.


Jet Jaguar's eyes also contain two spotlights, and he uses these to blind opponents or search for nearby humans or kaiju.


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 highly resourceful, demonstrated when he repurposed a ship's anchor into a makeshift flail against the Trilopods in Godzilla: Rulers of Earth.

Physical prowess

He is also able to carry incredibly heavy objects and even fly whilst being weighed down by Godzilla riding on his back.

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.

Size changing

The mechanical hero has the ability to alter his size at will. 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.

Liquid Nitrogen

During developments, Jet Jaguar was planned to spray liquid nitrogen from mouth, but was not made into movie. This was later used in Godzilla Island series for the firefighter type.


During developments, Jet Jaguar was planned to emit COMJAM, but was not made into movie.

Beam and sword and missile attacks

Outside of his film appearances he can fire beams from his arms along within missiles, similarly to Ultraman. In Godzilla: Save the Earth, the beam is rather sphere-shaped. In one of old stills, Jet Jaguar was seen using a sword of light.

Video games

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

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.

— Jet Jaguar Godzilla: Unleashed Bio

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.

Godzilla (2014 video game)

This remote-controlled robot was developed by the young scientist Goro Ibuki to support humans with their everyday tasks. It was operated remotely by radio waves transmitted from the scientist's laboratory. However, it was stolen by the Seatopians, descendants of inhabitants of the Lemurian continent that sank 3 million years ago, and was used as a vanguard for their land invasion.

Eventually, though, its built-in conscience began to kick in, causing it to become self-aware and autonomous. It grew in size in order to protect humankind, joining Godzilla to fight off the insect monster Megalon. The defeat of the sea kingdom resulted in Jet-Jaguar losing its self-awareness and returning to its regular size.

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: Rulers of Earth


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.


  • Jet Jaguar's design, and a number of his abilities such as the power to grow giant-sized, were based on Ultraman from the 1966 television series, Ultraman.
  • Jet Jaguar was renamed Jaguar J in Godzilla: Monster Apocalypse, created by the Earth Union through Bilusaludo-derived technology.
  • 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.
  • The popular 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. 
  • Jet Jaguar's Unleashed bio references his origins in Godzilla vs. Megalon, but doesn't state the reason why he was made from the film.
  • Jet Jaguar has a song about him played during the conclusion of Godzilla vs. Megalon.
