Sayonara, Yoshito. „ 

— Kiryu's final words, seen through a monitor within it.


Mechagodzilla (メカゴジラ,   Mekagojira?), nicknamed Kiryu (機龍,   Kiryū?, lit. Machine Dragon) is a cybernetically-enhanced mecha created by Toho that first appeared in the 2002 Godzilla film, Godzilla Against Mechagodzilla.


Kiryu's nickname is derived from 機龍?, Ki ryū, meaning machine dragon. Kiryu's legal name is simply "Mechagodzilla," while his official designation in the films is "MFS-3," which is short for "Multipurpose Fighting System Type-3."



This Mechagodzilla redesign is radically different from previous versions, and bears a closer resemblance to Godzilla himself. The MireMekagoji is light silver in color, with various areas on its body explosing thick black wires underneath. The head has a long metal spike extending from the top of its forehead upward towards the back of its head.

The eyes are large and relatively close together. They are usually yellow in color, but will turn red when Kiryu is possessed by the first Godzilla's spirit. A red scar extends underneath both eyes, and it will often glow when Kiryu roars.

The suit's chest features three rounded plates that come together to cover the Absolute Zero Cannon housed underneath. When the suit is used to portray Super Weapons Kiryu, two blue rocket launchers are attached to its shoulders, while blue railguns are attached to its wrists.


The TokyoMekagoji is nearly identical to its predecessor, the MireMekagoji, but has some differences upon closer examination. First of all, this suit is painted a darker gray color than the previous suit. This suit is overall thinner and more streamlined than the previous suit, and features a smaller head and shorter neck.

This suit's eyes are slightly smaller, and are further apart. The suit's chest is composed of three plates like the previous suit, however each one has a ridge on it, and the left chest plate has "MFS-3" written on it. The rest of the suit is mostly identical, although the exposed wires are a lighter shade of black, and there are many ridges and patterns present on the suit that were not present on the previous one.

The suit's rocket launcher's and railguns are the same color as the suit instead of being blue. After the suit is damaged in the battle with Godzilla, its right eye is removed, exposing more metal and wiring underneath.


Mechagodzilla was portrayed through the means of suitmation, much akin to its predecessors.


Mechagodzilla's roar during the Millennium series is a more mechanical sound, which is also mixed with Godzilla's guttural roar. The presence of Godzilla's roar in Mechagodzilla's roar varies, but is generally noticeable anytime it occurs. There are instances where its roar sounds similar to the Heisei Mechagodzilla.


Due to Kiryu having the original Godzilla's bones inside of him, Kiryu shares the kaiju's personality. Originally, Kiryu acts exactly like Godzilla, destroying everything in his path with malicious intent. However, as the story progresses, like Akane, Kiryu is implied to believe that he is not worth living for. It is only once in the final battle that Kiryu starts connecting with Akane, finding new purpose. Kiryu is also shown to be quite a brutal fighter, fighting Godzilla no matter what. By the end, it is shown that he has grown a connection to Akane.

In 2004, Kiryu is still the same in terms of personality, even with his new pilot. However, he is shown to be more empathetic to Godzilla, breaking out of his control and flying Godzilla to the bottom of the sea, sparing him and allowing Kiryu to rest in piece.


Kiryu was built around the remains of the original Godzilla and reanimated by the Anti-Megalosaurus Force.

In Godzilla: The Half-Century War, Kiryu is an updated version of the previous Mechagodzilla made after studying Godzilla's skeletal structure, with bits of Godzilla's skin built into its armor.


Godzilla Against Mechagodzilla

Kiryu in Godzilla Against Mechagodzilla

Although the original Godzilla had been killed in 1954 by the Oxygen Destroyer, Japan still found itself under attack from other monsters such as Mothra and Gaira over the decades. When a second Godzilla landed in Tateyama in 1999, this was the last straw. The Anti-Megalosaurus Force (AMF) division of the Japanese Xenomorph Self-Defense Force (JXSDF) proposed to dredge up the skeleton of the first Godzilla from Tokyo Bay and use it as a skeletal framework for constructing a Mechagodzilla.

The plan was executed, with cloned DNA from the bones inserted into the quasi-organic computer controls, intended to take over subconscious motor control functions for the crew. By 2003, the metal monster was ready. Kiryu was unleashed, but when the cyborg faced off against Godzilla, something horrific happened: the cyborg's own memories of when it was Godzilla were reawakened by the modern Godzilla's own roars. Kiryu broke free of its pilot, Akane Yashiro, and proceeded to trash Tokyo, ignoring attempts at manual override. Godzilla left the city and headed back to the ocean, with Kiryu continuing its rampage until its fuel ran out.

The Japanese public was not amused. Hastily recalled, Kiryu received quite a few weapon upgrades in addition to new computer control software routines. When Godzilla attacked again a few days later, both branches of the JSDF tried stopping him without the mecha's help, but it was useless. With Akane at the mecha's control again, Kiryu was sent out.

The second battle went well until Kiryu's receiver was damaged. Akane wanted to enter Kiryu and repair it herself despite orders against it. She then piloted the cyborg directly from its skull, carrying Godzilla out into the bay once more. Akane tried to destroy Godzilla with Kiryu's ultimate weapon, the "Absolute Zero Cannon", but the fight ended in a draw. Godzilla went back to the sea, though not before suffering a horribly shredded chest, and Kiryu went back to the body shop after suffering a destroyed right arm, a damaged Absolute Zero Cannon, and empty powercells.

Godzilla: Tokyo S.O.S.

Kiryu in Godzilla: Tokyo S.O.S.

One year later, in Godzilla: Tokyo S.O.S., Akane was sent to America for further flight training. Taking her place in case Godzilla appeared was Akiba, but Kiryu engineer Yoshito Chujo is the human focus of the film.

Mothra's twin fairies, the Shobijin, appeared to warn Japan. They claimed that building Kiryu using the bones of the Godzilla that appeared in 1954 was a violation of the natural order of things, attracting the current Godzilla. The twins further claimed that Mothra would gladly take Kiryu's place in protecting Japan if they agreed to dismantle Kiryu, and if they declined, Mothra would attack Japan. Since Kiryu had been built partially to defend against a second attack from Mothra herself, the Japanese declined.

But when Godzilla appeared and killed Kamoebas, Mothra voluntarily engaged him, and Prime Minister Hayato Igarishi was shamed into aiding her. Kiryu flew into battle again. Despite the team up, the current adult Mothra was killed and Kiryu's transmitter damaged once again. Just like Akane before him, Yoshito entered Kiryu for repairs, but remained inside the mech during the battle after Godzilla's beam had accidentally struck both of the hatch doors damaging and jamming it.

Teaming up with the newly-hatched twin Mothra larva, the modified 3-Kiryu (3式機龍改?) was able to use his drill in his right arm to injure Godzilla's chest even more, eventually reaching and tearing up his insides. While Godzilla screamed in pain, Kiryu fired his Triple Hyper Maser and Maser Cannons at Godzilla, making Godzilla's roar trigger another flashback in Kiryu which was directly channeled to Yoshito. Godzilla was then wrapped up by the twin Mothra larva web. Unable to fight, Godzilla dropped to the ground, allowing Kiryu to win the battle. Kiryu then broke free of Akiba's control. Instead of finishing his battle, he merely subdued Godzilla, carrying him out to sea. After releasing Yoshito to safety, Kiryu displayed a message saying "Sayonara Yoshito" on a computer monitor, then plunged into the depths with his organic counterpart, allowing himself to finally rest in peace, while ensuring Godzilla would survive. This marked the first time that Mechagodzilla was able to defeat Godzilla decisively by the end of a Godzilla film without Godzilla coming back to destroy him.


Absolute Zero Cannon

Kiryu test firing his Absolute Zero Cannon in Godzilla Against MechaGodzilla.

Kiryu's most devastating weapon is the Absolute Zero Cannon, (a weapon also utilized by the Gotengo.) Stored in its chest behind a trio of folding panels, the Absolute Zero Cannon fires a ball of energy that flash-freezes its target to Absolute Zero, thereby causing it to disintegrate under the weight of its own mass at the molecular level. Forty percent of Kiryu's power is devoted to using this weapon, thus leaving it as a finishing attack. The weapon is powered by an enormous synthetic diamond, which was damaged beyond repair after its second battle with Godzilla.

Alloy composition

While the Showa and Heisei Mechagodzilla are constructed of fictional alloys, it is never specified what Kiryu's armor is made out of. It is the first Mechagodzilla to include organic parts, built from the skeleton of the original Godzilla and using Godzilla's DNA in its computer system.


Like the previous Mechagodzillas, Kiryu was also able to fly; although its limited energy reserves required the machine to be airlifted to the battlefield by two White Herons. Kiryu is also incapable of unassisted takeoff, but was shown able to bound high enough into the air to clear several city blocks.

Overall firepower

Kiryu is a well balanced machine and far more agile than his previous incarnations, moving with a fluid, almost organic grace. Its armament includes oral maser cannons (Type 99, an improved model from Type 90 used in the Maser Cannon), dual laser cannons on each arm, and a flight pack that contains two forward firing rocket launchers and four batteries along its back and sides for launching guided missiles. Upon emptying its payload, the flight pack can detach from Kiryu's body and launched to push the enemy a safe distance back before being remotely detonated. In Tokyo S.O.S., the flight pack was replaced by weapons pods where rockets were fired; leaving the attached thrusters on Kiryu's body to maintain its aerial capabilities. In the Atari/Pipeworks trilogy of Godzilla video games, Mechagodilla had missile launchers hidden in its fingers.

Electric wrist blade

For close combat, a short blade can be extended from Kiryu's right wrist which was not only able to penetrate Godzilla's nearly impervious hide, but was also able to discharge a crippling electrical surge into his opponent's body.

Revolving drill

In Tokyo S.O.S., Kiryu's arsenal was upgraded to allow its right hand to collapse into a revolving drill. It did so by rapidly spinning until every finger merged together. It has shown to be very effective against Godzilla, causing extreme pain and piercing his skin with ease.

Tail use

Additionally, unlike previous Mechagodzillas, Kiryu's tail was able to move which allowed Kiryu to use it as an effective weapon, being able to knock Godzilla down with sheer force.

Triple Hyper Maser Cannon


After being heavily damaged in Godzilla Against Mechagodzilla, the Absolute Zero Cannon was deemed too expensive to repair and was replaced by a Triple Hyper Maser Cannon in Tokyo S.O.S. The Triple Hyper Maser Cannon could be fired simultaneously with Kiryu's mouth cannon, which would cause Godzilla agonizing pain.

Plasma Sword

In the Pipeworks/Atari trilogy of Godzilla Video Games, Mechagodzilla could manifest a plasma based dagger for close combat attacks. This can be done with either of his hands, and/or both, as seen from his moveset.


Godzilla's Soul

Certain actions by the second Godzilla, most frequently its own roars, were shown to trigger the dormant awareness of the original Godzilla within Kiryu, due to the fact its skeleton and DNA were incorporated into the mecha's construction. Upon awakening, Kiryu would lock out all external commands from a human operator and act under its new master, the soul of the original Godzilla, resulting in unrestrained, aimless destruction as long as it remained rampant.

Limited power

Because it has limited power reserves, Kiryu can only be in action for at most two hours or less, depending on its level of activity or when the use of Absolute Zero is involved.

Video games

Godzilla: Save the Earth

Kiryu returns in Godzilla: Save the Earth. Kiryu is an overall good fighter that is also one of the last unlocked. Kiryu can use its Mouth Cannon, Missiles, and Drill Hand to get an edge over his foes. His rage attack is the Absolute Zero Cannon which freezes his opponent while also dealing major damage.

Godzilla: Destroy All Monsters Melee

Kiryu was available in Japan's version of Godzilla: Destroy All Monsters Melee on the Nintendo GameCube. Since that film would take a few years to reach America, Kiryu was dropped from the American GameCube version of the game. However, he did appear in the American Xbox version of the game alongside the Heisei Mechagodzilla.

CR Godzilla 3S-T Battle

Kiryu appeared in Toho's 2006 CR Godzilla video game.

Godzilla: Domination!

Kiryu also appeared in the Japanese version of Godzilla: Domination!, but was replaced in the American version with the Heisei Mechagodzilla. Kiryu has the same exact moves as the Mechagodzilla in the American version. Kiryu character's drill hand goes entirely unused in this game. It should also be mentioned that the ending for Mechagodzilla still showcases the Heisei version as well.

Godzilla: Unleashed

Kiryu is a cyborg monster generated by the Global Defense Force to protect human cities from monster threats. Kiryu is genetically identical to Godzilla, but has been augmented with armor plating, enhanced reflexes, and limited flight capabilities.

These enhancements have eliminated his natural ability to create atomic fire, so he has been outfitted with homing rockets, an electrical cannon, and the fearsome Absolute Zero cannon-which can immobilize any monster in a single hit. Kiryu is the GDF's most successful defender yet, and is their first and best option for defending humanity.

— Millennium Mechagodzilla bio

Mechagodzilla also appeared in Godzilla: Unleashed for the Nintendo Wii and PlayStation 2 under his actual name from both Godzilla Against Mechagodzilla and Godzilla: Tokyo S.O.S., "Kiryu."

Godzilla Unleashed: Double Smash

Kiryu appeared within the DS title Godzilla Unleashed: Double Smash.

Godzilla On Monster Island

Kiryu made an appearance within the game Godzilla On Monster Island.

Godzilla (2014 video game)

A bio-mechanical weapon using as its mainframe the bones of the original Godzilla, which were salvaged from the bottom of Tokyo Bay under the utmost secrecy, and using a DNA computer that utilizes the bone marrow stromal cells for its regulatory transmission system. The Anti-Megalosaurus Force (AMF) division of the Japan Counter-Xenomorph Self-Defense Force (JXSDF) operates it via remote control from the "AC-3 White Heron" support aircraft. Its standard name is "Multi-Purpose Fighting System 3" (Model number MFS-3) and its alias "Kiryu."

It comes armed from head to toe with beam weapons and rocket projectiles, with the additional option to mount powerful weapons on its back. Its ultimate weapon is "Absolute Zero", mounted inside its chest hatch and capable of shooting -273.15°C energy balls that disintegrate its enemies at the molecular level. It was able to hold its own against Godzilla at mid- and close-range combat. However, after being activated and facing off against Godzilla, its DNA computer resonated to the sound of Godzilla's roars, causing a malfunction and sending it on a rampage through the vicinity of Yokohama Hakkeijima.

Kiryu's suit was made as lightweight as possible, enabling it to throw punches, shake its tail, grab and throw its adversaries, and perform other quick intense actions, successfully establishing an entirely new image for Mechagodzilla.

— Kiryu Kaiju Guide bio

A newly modified version of the MFS-3 mechanical weapon, after the original was 37% destroyed by Godzilla the year before. Model number: MFS-3. Though neither its basic performance nor output have changed, new equipment has been added and its offensive power has been amplified. A tri-shot Hyper maser has been installed in place of the Absolute Zero in its chest, and its right hand can transform into a drill-type Spiral Claw at its wrist.

In the midst of a battle with Mothra, Kiryu's computer became self-aware and threw off the control of its operators. The newly sentient Kiryu sent the message "Sayonara Yoshito" to Yoshito Chujo, the engineer who made life-saving repairs to the robot, and plunged itself along with Godzilla into the depths of the Japan Sea.

For Modified Kiryu's special-effects scenes, the costume was filmed on a real set, then merged with CG animation to create dynamic footage.

— Kiryu Kaiju Guide bio

In the PS3 version, Kiryu appears as one of the final bosses if Godzilla has reached 100 meters. He will only be summoned if the G-Generators are destroyed fast enough. If they are not, Super Mechagodzilla will appear instead. Kiryu attacks using his battle pack at first, then switch to melee attacks and the Hyper-Maser once the pack is destroyed. If he is defeated, he will appear in the end cutscene carrying a frozen Godzilla back to the ocean, sinking with him. This is a reference to Godzilla: Tokyo S.O.S..

In the PS4 version, Kiryu will be summoned on stage 8 with the Gotengo if the player takes the hard route all the way through.

Godzilla: Kaiju Collection

Kiryu made an appearance within the mobile title Godzilla: Kaiju Collection.

City Shrouded in Shadow

Mechagodzilla in its original form appears in the game to fight Godzilla, however it goes on a rampage. The coloration of its oral maser is blue unlike in the films, where it's yellow.

Super Robot Wars X-Ω

Godzilla vs. Evangelion was a fake film announced by Toho on the 2014 April Fool's Day to promote Shin Godzilla (also known as Godzilla: Resurgence) and Evangelion: 3.0+1.0, also being a nod to Hideaki Anno working on both films.

Despite being a fake film, the "series" was featured in Super Robot Wars X-Ω in an event from August 2016, celebrating the release of Shin Godzilla. During the event, Godzilla and two versions of Mechagodzilla (Kiryu) appeared as playable units that could be obtained. This marked the first appearance of a kaiju in the Super Robot Wars series.


Godzilla: Ongoing

Kiryu appears in Godzilla: Ongoing where he is constructed by billionaire Daniel Malmon to replace the previous Mechagodzilla. Kiryu battles Godzilla and briefly has the upper hand. Kiryu attempts to use his Absolute Zero cannon on Godzilla, but Godzilla counters it with his atomic breath, creating a beam clash which Kiryu loses. With Kiryu damaged and immobile, Godzilla leaves.

Kiryu is later stolen by Harrison, Boxer's estranged son and a member of his "Kaiju Kill Crew" and sent to Monster Island to free the Earth monsters being contained there so that they can battle the space monsters. Kumonga hitches a ride on Kiryu's back while Boxer and Hikari join Harrison in the cockpit, and Kiryu heads to New York to take on Monster X. Monster X easily beats Kiryu and Kumonga before SpaceGodzilla and Godzilla both arrive. During the ensuing battle, Kiryu is knocked into the Hudson River. As Kiryu begins to flood and sink, Boxer manages to get the Absolute Zero cannon operational. Using a well-timed shot, Kiryu freezes SpaceGodzilla, rendering him helpless while Godzilla blasts him and apparently destroys SpaceGodzilla.

Godzilla: The Half-Century War

Kiryu appears in The Half-Century War #5, where he is constructed by the Anti-Megalosaurus Force. Kiryu is deployed to Antarctica where the AMF has just completed constructing the Dimension Tide, which they hope will finally stop the space monsters King Ghidorah and Gigan. Godzilla arrives and battles the space monsters, but is badly outmatched. Luckily, Ota Murakami takes command of Kiryu and assists Godzilla in the battle. The AMF activates the Dimension Tide, and the combined efforts of Kiryu and Godzilla manage to banish Gigan and King Ghidorah into a black hole. Before Godzilla can escape, Kiryu stabs him and holds him still. As the black hole tears Kiryu apart, the cockpit is exposed, allowing Murakami to finally see Godzilla face-to-face. Eventually, the force of the black hole destroys Kiryu and apparently sucks Godzilla in as well, though Godzilla's dorsal plates are visible breaking the water in the aftermath of the battle.

Godzilla: Rulers of Earth

Kiryu appears in Rulers of Earth #11, now upgraded to his Modified Type-3 Kiryu design. In this issue, Kiryu is sent to Paris to subdue Baragon. Baragon breathes fire at Kiryu and fights fiercely, but Kiryu is able to overcome and capture Baragon, after which he brings Baragon to the new Monster Islands.

In Rulers of Earth #12, Kiryu is sent along with a naval fleet to assault the Devonian capital. However, Destoroyah attacks the fleet and kills Kiryu's pilot. Jet Jaguar realizes that he is no match for Destoroyah, and decides to shrink to human size and pilot Kiryu. Jet Jaguar uses Kiryu's Absolute Zero cannon to freeze Destoroyah, killing him in one hit.

In Rulers of Earth #14, Kiryu is sent to Antarctica to recover the supposed dead body of Anguirus following his battle with a Mechagodzilla. When it is discovered that Anguirus is still alive, Kiryu restrains him and is ordered to fly Anguirus to a secret facility in Russia. On the way there, Kiryu and the jets escorting him are attacked by a group of Mechagodzillas. Kiryu is shot down over Russia while Anguirus escapes to go join Godzilla in battle against Mecha-King Ghidorah and more Mechagodzillas.

Kiryu was later repaired and joined the massive counter attack against the Trilopods. The mech managed to freeze a Baragon Trilopod, before getting pounced on and destroyed by the Varan and Sanda Trilopods.

Godzilla in Hell

During the opening battle between Godzilla and SpaceGodzilla in Rio de Janeiro in Godzilla in Hell #3, what appears to be one of Kiryu's arms can be seen laying under a pile of rubble next to the ruins of M.O.G.U.E.R.A.

Godzilla: Oblivion

Kiryu appeared in the first issue of Godzilla: Oblivion. In this comic, Kiryu was present in an alternate dimension, where he was seen battling a small version of Rodan. Kiryu had the upper hand, until more Rodans appeared and began to give him some trouble.

In the the third issue, after salvaging the metals from the other dimension, Earth scientists used their replicators on them, and used them to build an army of Kiryus in order to fight Godzilla. The Kiryus attacked Godzilla over the open ocean, distracting him while the humans salvaged the carcass of King Ghidorah and revived him as the more powerful Mecha-King Ghidorah. When Godzilla eventually destroyed all of the Kiryus with his atomic breath and claws, he pursued the humans to their base and engaged Mecha-King Ghidorah.

In other languages

Kiryu has very little translations compared to his alternate title. Latin alphabets are generally the same. Other translations:

  • Chinese: 机龙
  • Serbian: Кириу
  • Russian: Кирью
  • Yiddish: קיריו


  • This is the second incarnation of Mechagodzilla to be created by humans.
  • When Kiryu is remembering its past, Kiryu's eyes turn red. Yet when the spirit is not evil, part of its head turns red without the red eyes(this is meant to imply that the spirit inside Kiryu is weeping, as it appears to be in anguish upon realizing what he had done).
  • The idea of having the ghost of the original Godzilla come back to life was tossed around for the cancelled Godzilla vs. Ghost Godzilla.
  • Alongside the Showa Mechagodzilla, Kiryu is the second Mechagodzilla to defeat Godzilla more than once.
  • Kiryu is the first Mechagodzilla that could use its tail to attack since Kiryu has the original bones of Godzilla, allowing its tail to move. This also grants Kiryu some increased mobility in conjunction with its rotatable rocket boosters, as Kiryu can use its tail like a rudder to steer.
  • Kiryu is the second Mechagodzilla to appear in more than one movie, with the first being the original Mechagodzilla.
  • The rocket launchers which Kiryu wears are a reference to Super Mechagodzilla's Garuda cannons.
  • Kiryu is featured in the 2011 sci-fi novel Ready Player One. The novel's antagonist, Nolan Sorrento, selects Mechagodzilla from a list of giant robots to control in the OASIS, a MMO game which acts as the novel's primary setting. Sorrento later activates Mechagodzilla in battle by shouting "Kiryu!". Kiryu is eventually defeated by the novel's protagonist, Wade Watts, who transforms into another iconic Japanese giant, Ultraman.
    • In the movie adaptation of Ready Player One, a completely different version of Mechagodzilla with a design modelled after the MonsterVerse version of Godzilla, appears in much the same role as above. However, there is no mention of Kiryu, and instead of Wade transforming into Ultraman to battle Mechagodzilla, his friend Daito instead transforms into the RX-78-2 Gundam to fight, along with Aech, who takes on the form of The Iron Giant, the RX-78-2 Gundam damages but does not wholly destroy Mechagodzilla, but The Iron Giant continued to fight against him(Ultraman's abscence is due to the fact that Warner Bros. Pictures was unable to secure licensing rights to use Ultraman). Art3mis manages to toss a grenade into Mechagodzilla's head. The resulting explosion finally destroyed it once and for all. Its armaments consisted of Finger missiles and a Laser Cannon located in its mouth.
