{{Nihongo|'''Mechagodzilla'''|メカゴジラ|Mekagojira|lead=yes}} is a fictional [[mecha]] character, or [[monster]], that first appeared in the 1974 film ''[[Godzilla vs. Mechagodzilla]]''. In its debut appearance, Mechagodzilla is depicted as an [[Extraterrestrials in fiction|extraterrestrial]] villain, a [[robot]] created by alien invaders to confront and destroy [[Godzilla]]. In subsequent iterations, Mechagodzilla is usually depicted as a man-made artificial weapon designed to defend [[Japan]] against Godzilla and other [[kaiju]]. In all incarnations, the character is portrayed as a robotic [[doppelgänger]] of Godzilla with a vast array of high-tech weaponry. Along with [[King Ghidorah]], Mechagodzilla is commonly considered to be an [[archenemy]] of Godzilla.

==Overview==
===Development===
Mechagodzilla was conceived in 1974 as a more serious villain than its immediate two predecessors, [[Gigan]] and [[Megalon]], whose films were considered creative disasters.{{sfn|Ryfle|1998|p=195}}{{sfn|Ryfle|1998|p=196}}{{sfn|Ryfle|1998|p=197}} According to [[Tomoyuki Tanaka]], Mechagodzilla was inspired by both [[Mechani-Kong]] from the previous [[Toho]] film ''[[King Kong Escapes]]'' and the [[Mecha anime and manga|robot anime]] genre, which was popular at the time.<ref name="元山掌">{{cite book |author1=元山掌|author2=松野本和弘|author3=浅井和康|author4=鈴木宣孝 |script-title=ja:『東宝特撮映画大全集』 ヴィレッジブックス |year=2012 |publisher=ヴィレッジブックス |isbn=9784864910132}}</ref> Effects director [[Teruyoshi Nakano]] also felt that a mechanical monster was cheaper to construct than the mutated animals Godzilla had previously faced.{{sfn|Kalat|2010|p=137}}{{sfn|Kalat|2010|p=138}}{{sfn|Kalat|2010|p=139}} As the resulting ''[[Godzilla vs. Mechagodzilla]]'' proved to be a greater critical success than previous 1970s ''Godzilla'' films, the character was revived in 1975's ''[[Terror of Mechagodzilla]]''. The film's screenplay was based on the winning entry of a story-writing competition won by [[Yukiko Takayama]], who continued the darker tone of the previous film by adding the subplot of Mechagodzilla being cybernetically connected to a young woman. Mechagodzilla's design remained largely unchanged from its previous appearance, though it was made to look thinner and more angular, with a darker sheen and an MG2 insignia emblazoned on its upper arms. The film's original draft was going to have Mechagodzilla destroy Tokyo utterly, though the destruction was cut down for budgetary reasons.{{sfn|Ryfle|1998|p=200-6}}
[[File:Heisei Godzilla Perfection - Berserk.jpg|thumb|right|Early concept art of Mechagodzilla's Heisei incarnation, dubbed "Berserk"]]

Mechagodzilla was brought back in 1993's ''[[Godzilla vs. Mechagodzilla II]]'', as the success of ''[[Godzilla vs. Mothra]]'' and the popularity of its main antagonist [[Mothra]] spurred Toho into reintroducing familiar characters rather than inventing new ones.{{sfn|Ryfle|1998|p=287-93}} Originally, the new Mechagodzilla was to be named "Berserk", and was envisioned as being a much more organic Godzilla-like creature which would later turn on its creators after becoming infected with a [[computer virus]] which makes it self-aware. Berserk would subsequently absorb more and more machinery, to the point of degenerating into a mass of metal and wires, though this concept was rejected early in pre-production.<ref name="kawakita">{{cite book |script-title=ja:平成ゴジラパーフェク [Heisei Godzilla Perfection] |last=Kawakita |first=Koichi |year=2012 |publisher=Dengeki Hobby Books |isbn=978-4048861199 |language=ja}}</ref> As Mechagodzilla was intended to be a military defense weapon rather than an alien construct, the character was redesigned as looking sleeker and smoother.{{sfn|Ryfle|1998|p=287-93}} It was portrayed by suit actor [[Wataru Fukuda]], and consisted of multiple separate elements which were worn like plate armor. Special effects artist [[Koichi Kawakita]] originally envisioned Mechagodzilla being able to split into aerial and terrestrial units, though this idea was scrapped in favor of the character merging with the flying battleship Garuda. The film was promoted through the children's program ''Adventure Godzilla-land'', which portrayed Godzilla and Mechagodzilla as rival news anchors reporting on the events of the upcoming movie.{{sfn|Kalat|2010|pp=196–201}} Composer [[Akira Ifukube]] wrote a theme for Mechagodzilla incorporating a slow battle march with heavy percussion and [[Pentatonic scale|pentatonic phrasing]].{{sfn|Ryfle|1998|p=287-93}}

The decision to incorporate Mechagodzilla into the Millennium series was taken by producer [[Shōgo Tomiyama]], who gave the general outline of what would become the story of ''[[Godzilla Against Mechagodzilla]]'' to ''[[Godzilla vs. Megaguirus]]'' director Masaaki Tezuka.<ref name="tezuka2014">{{cite web |url=https://www.youtube.com/watch?v=0toUtvfWMPg  |archive-url=https://ghostarchive.org/varchive/youtube/20211212/0toUtvfWMPg| archive-date=2021-12-12 |url-status=live|trans-title="Tokyo SOS Director EXTRA |script-title=ja:東京SOSの監督〜EXTRA〜 (SciFi Japan TV #27) |publisher=CHO Japan |date=September 2014}}{{cbignore}}</ref> Tezuka instructed his staff to research both [[cybernetics]] and DNA engineering in order to make the character scientifically plausible. Tezuka had initially wanted Mechagodzilla to be a much speedier robot than the one on film, envisioning it as becoming progressively more agile during its fight against Godzilla as the latter tore off its opponent's armaments. This incarnation of Mechagodzilla was deliberately shown being airlifted by carriers rather than flying directly into battle as the previous two incarnations had done, as Tezuka felt that it made little sense for Mechagodzilla to drain its energy in such a manner. Upon being asked why the Mechagodzilla suit wasn't painted with [[military camouflage]] colors, Tezuka answered that "Mechagodzilla doesn't need to hide."<ref>{{cite web |url=http://www.henshinonline.com/tezuka-mimura.html |title=Interview: Masaaki Tezuka and Wataru Mimura |access-date=2016-05-26 |url-status=dead |archive-url=https://web.archive.org/web/20160701043428/http://www.henshinonline.com/tezuka-mimura.html |archive-date=2016-07-01 |work=henshionline}}</ref> Tezuka had originally intended to have both Godzilla and Mechagodzilla die at the end of the film, but was forced to change this on the insistence of Toho managers, who felt that such an ending was too dark for a [[New Year]] movie release.<ref name="tezuka2014"/>

In the 2003 sequel ''[[Godzilla: Tokyo S.O.S.]]'', creature designer Shinichi Wakasa used the same mold to create a redesigned Mechagodzilla, which was meant to look more weathered than its predecessor. According to production designer Shinki Nishikawa, several other changes were made to the Mechagodzilla design's head, chest and arms in order to make the character look less heroic and more machine-like. The robot's back unit was reduced in size and flipped upside down, and the head was made smaller. As the previous design's shoulder cannons were considered uneven and unsophisticated-looking because of their rectangular shape, special effects director Eiichi Asada made them more pentagonal. As the character was supposed to rely more on its forearm cannons than in the previous film, Nishikawa made them larger and more powerful looking.<ref>"Godzilla X Mothra X Mechagodzilla: Tokyo SOS production report - The men behind the monsters discuss the latest Godzilla film", ''Uchusen'' #108 (Asahi Sonorama) (October 22, 2003)</ref>

For ''[[Godzilla vs. Kong]]'', Mechagodzilla's design was inspired by the [[Transformers: Generation 1|Generation 1 ''Transformers'']] due to their "simplicity." Director [[Adam Wingard]] attempted to avoid the "complex" designs from the [[Transformers (film series)|Michael Bay ''Transformers'']] films.<ref>{{cite web|url=https://www.inverse.com/entertainment/mechagodzilla-godzilla-vs-kong-design-changes-transformers|title= Godzilla vs. Kong's Mechagodzilla was inspired by a bad Transformers movie|author1=Jake Kleinman|author2=Eric Francisco|work=Inverse|date=March 31, 2021|access-date=April 9, 2021|url-status=live|archive-date=April 9, 2021|archive-url=https://web.archive.org/web/20210409191637/https://www.inverse.com/entertainment/mechagodzilla-godzilla-vs-kong-design-changes-transformers}}</ref> Writer [[Max Borenstein]] had originally written Mechagodzilla into ''Godzilla: King of the Monsters''.

===Arsenal===
[[File:Mechagodzilla Absolute Zero.png|thumb|Kiryu's Absolute Zero Cannon in ''Godzilla Against Mechagodzilla'' (2002)]]
The Showa Mechagodzilla stands {{convert|50|m|ft|abbr=on}} in height and weighs 40,000 metric tons.{{sfn|Ryfle|1998|p=196}} It is built from "space [[titanium]]", and is capable of launching missiles from its fingers, toes and knees, as well as firing Space Beams from its eyes and a Cross Attack Beam from its chest unit. It also possesses jets in its feet, allowing it to fly. Its head can spin 360°, and can form a [[force field (fiction)|force field]] capable of repelling and shocking opponents.<ref name="GvMG">''[[Godzilla vs. Mechagodzilla]]'' (1974). Directed by [[Jun Fukuda]]. [[Toho]]</ref> The upgraded model featured in ''Terror of Mechagodzilla'' included revolving missiles, and was no longer vulnerable to decapitation, as its main computer was housed in an external power source. Once Mechagodzilla's head was removed, the machine was able to continue to fight, possessing a Head Controller capable of firing a concentrated laser with the same strength as its regular beams.<ref name="ToMG">''[[Terror of Mechagodzilla]]'' (1975). Directed by [[Ishirō Honda]]. [[Toho]]</ref>

The Heisei Mechagodzilla stands at {{convert|120|m|ft|abbr=on}} in height, weighs 150,000 metric tons, and is powered by a [[nuclear reactor]] which derives its energy from [[heavy hydrogen]] and [[helium-3]] in pellet form. Its frame is coated in an armor made of synthetic diamond codenamed T-1, allowing the robot to resist and repel Godzilla's atomic breath, as well as absorb its power to energize its Plasma Grenade, an energy weapon housed in its abdomen. Additional armaments include Mega Buster ray fired from its mouth, Laser Cannons in its eyes, missiles fired from its shoulders and hips, jet propulsors on its back and behind its hips to fly and two harpoons known as the G-Crusher fired from its arms. The G-Crusher is capable of sending large amounts of electric current through the cables. The model is later combined with the flying battleship Garuda, thus allowing it to hover and adding two additional [[Maser]] Cannons to its arsenal.<ref name="GvMGII">''[[Godzilla vs. Mechagodzilla II]]'' (1993). Directed by [[Takao Okawara]]. [[Toho]]</ref>

Kiryu, the Millennium Mechagodzilla, stands at {{convert|60|m|ft|abbr=on}} in height, weighs 40,000 metric tons, and is piloted remotely from a control craft. The mecha can be remotely recharged from the ground using microwaves that are relayed through a power system on one of the command aircraft, and then beamed back down to the robot. Its armaments include a Twin Maser Cannon in its mouth, [[railgun]]s on its hands, a maser blade on its right hand, two reactors on its back to fly, a back unite with missiles and boosters and two rocket launchers on its shoulders. Its most powerful and most energetically costly weapon is the Absolute Zero Cannon housed in its chest, which fires a beam capable of [[flash freezing]] enemies.<ref name="GaMG">''[[Godzilla Against Mechagodzilla]]'' (2002).

The Anime Trilogy Mechagodzilla stands 50 meters in height, weighs 30,000 metric tons, and is powered by artificial intelligence and made from nanometal. In the novel: ''Project Mechagodzilla'', its arsenal includes a Blade Launcher, Convergent Neutron Cannon, Flight, Hyper Lance, Thermal Energy Buffer Layer, and Tail Blow. When it forms Mechagodzilla city, the defenses include gun cannons, EMP Harpoons, and a force field to protect itself when fired upon.

In ''[[Godzilla vs. Kong]]'', Mechagodzilla stands at {{convert|122|m|ft|abbr=on}} in height, towering over Godzilla, weighs 100,000 metric tons, and is telepathically piloted through a cybernetic neural network developed from [[King Ghidorah]]'s only surviving brain (from a head severed by Godzillia in [[Godzilla: King of the Monsters (2019 film)|''Godzilla: King of the Monsters'']]). Its weaponry includes a Proton Scream fired from its mouth, missiles fired from its shoulders and chest, jet boosters on its back, plasmic hits, buzzsaws in its fingers and spinning spikes at the end of its tail.

==Film history==
===Shōwa period (1974–1975)===
[[File:Mechagodzilla 1974.png|thumb|Shōwa Mechagodzilla]]
In ''[[Godzilla vs. Mechagodzilla]]'', Mechagodzilla is created by the Black Hole Planet 3 aliens, also known as the Simians, in order to conquer Earth before their homeworld gets destroyed by an expanding [[black hole]]. First appearing in a pseudo-flesh outer covering and masquerading as the real Godzilla, Mechagodzilla attacks Japan and overpowers Godzilla's ally [[Anguirus]]. Godzilla appears and destroys the pseudo-flesh disguise, forcing Mechagodzilla to reveal itself in full. Their initial battle results in a tie, as Godzilla is severely wounded and Mechagodzilla is forced back into the Simian's base for repair. Mechagodzilla is deployed again but is overpowered through the combined efforts of Godzilla and [[King Caesar]]. Godzilla ultimately defeats Mechagodzilla by decapitating it, and Mechagodzilla subsequently explodes upon the self-destruction of the Simians' base.

The Simians, now under the leadership of Mugal, return and rebuild Mechagodzilla in ''[[Terror of Mechagodzilla]]''. This time, it is further modified with living human brain cells and has its control circuitry integrated into the body of the formerly human [[cyborg]] Katsura Mafune. Mechagodzilla is teamed up with the dinosaur [[Titanosaurus (Godzilla)|Titanosaurus]], who is controlled by Katsura's crazed father. Although Mechagodzilla survives another decapitation during a battle against Godzilla, it is once more defeated after Katsura commits suicide, destroying the robot's controls and freezing it long enough for Godzilla to use its atomic heat ray on Mechagodzilla's headless body, causing it to explode.

===Heisei period (1993)===

[[File:Heisei Mechagodzilla.png|thumb|Heisei Mechagodzilla, dubbed Super Mechagodzilla.]]
In ''[[Godzilla vs. Mechagodzilla II]]'', Mechagodzilla is built as an anti-Godzilla weapon by the United Nations Godzilla Countermeasures Center using 23rd-century technology [[Reverse engineering|reverse engineered]] from the remains of [[King Ghidorah|Mecha-King Ghidorah]]. Mechagodzilla overpowers Godzilla in Kyoto, but is rendered harmless by a voltage backsurge caused by Godzilla. Mechagodzilla is recovered and merged with the smaller airship Garuda to form {{nihongo|'''Super-Mechagodzilla'''|スーパーメカゴジラ|Supa-Mekagojira}}. This combined mecha later fights both [[Rodan|Fire Rodan]] and Godzilla. He proceeds to cripple Godzilla by destroying his secondary brain and mortally wounds Rodan. Rodan then sacrifices his energy to revive Godzilla, who then uses his new red spiral atomic breath to destroy the weakened Super-Mechagodzilla.

In ''[[Godzilla vs. SpaceGodzilla]]'', it is revealed that Mechagodzilla's remains were salvaged and used to construct [[Moguera]].

===Millennium period (2002–2003)===
[[File:Millennium Mechagodzilla.png|thumb|Millennium Mechagodzilla, dubbed Kiryu.]]
The Millennium incarnation is featured in two films: ''[[Godzilla Against Mechagodzilla]]'' and ''[[Godzilla: Tokyo S.O.S.]]'' and is referenced as {{nihongo|'''Kiryu'''|機龍|Kiryū}}, derived from '''Kikai Ryu''' (Japanese for "machine dragon") or "Kōryū" (Japanese for steel dragon). When a second Godzilla appears in 1999, the Japanese military creates a Mechagodzilla built around the skeleton of the original Godzilla from 1954 and a [[DNA computing]]-based operating system. During its first battle with Godzilla four years later in 2003, Kiryu's genetic memories of its 1954 incarnation are awakened, and it proceeds to attack Tokyo, free from the controls of its pilot until its power drains. During its second battle with Godzilla, Kiryu forces Godzilla to retreat after using its Absolute Zero Cannon.

In ''[[Godzilla: Tokyo S.O.S.]]'', taking place one year later in 2004, [[Mothra]]'s fairies warn Japan that Kiryu's creation is a violation of the natural order and that Mothra would gladly take the cyborg's place in protecting Japan, should Kiryu be dismantled. The ultimatum is declined, as Kiryu was built partially to defend against a second attack from Mothra herself. Godzilla eventually appears, prompting Mothra and Kiryu to cooperate. Kiryu momentarily is forced to fight Godzilla alone after Mothra is killed, but is later assisted by Mothra's larvae, who encase Godzilla in a cocoon, and Kiryu is given orders to terminate him. However, Kiryu's soul has awakened once again, and it instead grabs hold of Godzilla, flies out to sea, and submerges both Godzilla and itself in the depths of the ocean (though not before ejecting its human occupant to safety).

===Reiwa period (2017–2018)===
Mechagodzilla appears briefly in ''[[Godzilla: Planet of the Monsters]]'', the first film in the anime trilogy. The mecha is designed and constructed by humans and bilusaludo - the latter one of two alien races who made contact with humans in an attempt to rescue them - as a countermeasure against Godzilla. But the mech is never activated as Godzilla attacked the construction facility forcing them to abandon it. Though not seen again, the mech is referenced several other times throughout the film. In ''[[Godzilla: City on the Edge of Battle]]'', the second film in the trilogy, the remnants of Mechagodzilla's AI rebuild the facility it was created in by utilizing nanometal to help defeat Godzilla, aptly named "Mechagodzilla City". It also creates three battlesuits with flight capabilities called "Vultures".

Haruo and his forces use the city as a base of operations to destroy Godzilla. When Mechagodzilla City begins assimilating its surroundings and living beings with its nanometal under the command of the Bilusaludo, and is predicted to assimilate the entire planet prompting Haruo to destroy its command center, giving Godzilla the opening to destroy it. In ''[[Godzilla: The Planet Eater]]'', some nanometal survives within Yuko's body which Professor Martin extracts and applies to the last ''Vulture'' intending to rebuild civilization. Realizing this will only repeat the mistakes that prompted Godzilla's advent, endanger the Houtua and risk the return of Ghidorah, Harou takes Yuko and the last Vulture and flies all three towards Godzilla in a suicide charge to save the Houtua from mankind's mistakes.

===MonsterVerse (2021)===
Mechagodzilla was featured in the 2021 film ''[[Godzilla vs. Kong]]''.<ref>{{cite web|url=https://screenrant.com/mechagodzilla-design-look-godzilla-vs-kong-comparison-differences/|title=How Mechagodzilla's Design In Godzilla vs Kong Compares To Past Versions|first=Nicholas|last=Raymond|work=Screen Rant|date=April 6, 2021|access-date=March 29, 2022|url-status=live|archive-date=March 29, 2022|archive-url=https://web.archive.org/web/20220329190147/https://screenrant.com/mechagodzilla-design-look-godzilla-vs-kong-comparison-differences/}}</ref> Secretly built by Apex Cybernetics as an anti-Titan weapon, it is designed to wipe out the Titans and replace [[Godzilla (Monsterverse)|Godzilla]], remotely piloted by Ren Serizawa via a [[Telepathy|telepathic]] link originating from a skull of [[King Ghidorah|Ghidorah]]'s left head (acquired after it was torn off by Godzilla in ''[[Godzilla: King of the Monsters (2019 film)|Godzilla: King of the Monsters]]'' prior), though conventional energy sources prove insufficient to power it to full capacity.

As Mechagodzilla is being built at a facility in [[Pensacola, Florida]], Godzilla senses Ghidorah's presence whenever the mecha activates, which causes him to search for and eventually attack the facility. Due to the secrecy of the project, the public misinterprets this as Godzilla having gone rogue, resulting in Monarch and Apex taking [[King Kong|Kong]] to the [[Hollow Earth]] in search of an energy source to confront Godzilla with; simultaneously, Apex covertly plans to use it to power Mechagodzilla, now housed within [[Victoria Peak]]. Godzilla and Kong clash en route to the Hollow Earth in the [[Tasman Sea]], but ultimately the team finds and retrieves the power source, in the form of "Hollow Earth Energy".

After Godzilla and Kong fight a second time in [[Hong Kong]], Serizawa charges the mechanized titan with the untested Hollow Earth's energies, upon pressure from Apex Cybernetics' [[Chief executive officer|CEO]] Walter Simmons. However, the process unexpectedly allows Ghidorah's mind to possess Mechagodzilla, who then kills both Simmons and Serizawa, goes on a rampage in the city, and faces Godzilla. Godzilla is easily overwhelmed, and is nearly killed before Kong joins the battle. Kong's axe initially proves ineffective against Mechagodzilla, as its energy was depleted after battling Godzilla. As Mechagodzilla maintains the upper hand, Josh Valentine tampers with its control panel via alcohol spillage, stalling it long enough for Godzilla to supercharge Kong's axe with his atomic breath. Kong then uses his fully powered axe to dismember Mechagodzilla's limbs, and finishes it off by tearing off its head.

==In other media==
The various incarnations of Mechagodzilla have appeared in other media associated with the series, such as video games, television shows, and comics.

===In video games===
The Shōwa Mechagodzilla appears in the video games ''[[Godzilla: Monster of Monsters]]'' for the [[Nintendo Entertainment System]], ''[[Godzilla (Game Boy)|Godzilla]]'' for the [[Game Boy]], ''[[Super Godzilla]]'' for the [[Super Nintendo Entertainment System|Super NES]] (American release; replaces the Heisei version from the Super Famicom release, since the Heisei incarnation's film had yet to be released in America when the game was released), ''[[Godzilla: Battle Legends]]'' for [[TurboGrafx-16]], ''[[Godzilla Generations]]'' for the [[Dreamcast]] (erroneously using his Heisei counterpart's sound effects) and ''[[Godzilla Generations: Maximum Impact]]'' for the Dreamcast and the [[Wii]] version of ''[[Godzilla: Unleashed]]''.

The Heisei Mechagodzilla appeared in the video games ''[[Super Godzilla]]'' (Japanese version, replaced by the Showa Mechagodzilla in the English release) and ''[[Godzilla: Monster War]]'', both for the [[Super Nintendo Entertainment System|Super NES]], ''[[Godzilla: Domination|Godzilla: Domination!]]'' for [[Game Boy Advance]], ''[[Godzilla: Save the Earth]]'' for [[Xbox (console)|Xbox]] and [[PlayStation 2]], ''[[Godzilla: Destroy All Monsters Melee]]'' for Xbox and [[GameCube]], and [[Wii]] and [[PlayStation 2]] versions of ''[[Godzilla: Unleashed]]''.

Kiryu first appeared in the Japanese version of ''[[Godzilla: Destroy All Monsters Melee]]'' on the [[GameCube]]. Since the Millennium Mechagodzilla duology would take a few years to reach US stores, it was dropped from the American version of the game, but did appear as an exclusive in the Xbox version. Kiryu was next playable in ''[[Godzilla: Save the Earth]]'' for the [[Xbox (console)|Xbox]] and the [[PlayStation 2]] under the title "Mechagodzilla 3"; this would be Kiryu's first PS2 appearance in the United States. Kiryu also appears in both versions of ''[[Godzilla: Unleashed]]'', for the first time under the name "Kiryu" as opposed to its names in the two previous games; "Millennium Mechagodzilla" and "Mechagodzilla 3".

Like the other kaiju in the game, the backstories of all three Mechagodzilla incarnations are altered slightly, to fit the context of the game. The Heisei Mechagodzilla and Kiryu are man-made mecha created by the G.D.F. (Global Defense Force) faction to defend Earth from the Vortaak and their kaiju of the aliens' faction. The original Showa Mechagodzilla was salvaged and rebuilt by the Vortaak to be used in their kaiju force.

In the PlayStation 4 version of ''[[Godzilla (2014 video game)|Godzilla]]'', 4 incarnations of Mechagodzilla appear, the original Showa Mechagodzilla appears as both Mechagodzilla from ''Godzilla vs. Mechagodzilla'' and as Mechagodzilla 2 the rebuilt Mechagodzilla from ''Terror of Mechagodzilla''. The Heisei Mechagodzilla appears in its Super Mechagodzilla form, while Kiryu appears in its rebuilt design from ''Tokyo S.O.S.'' In the PS4 version, all 4 Mechagodzilla are playable, the 2 versions of the Showa Mechagodzilla can be played in God of Destruction Mode via the Invade option (which allows the mode to be played using Kaiju other than the Heisei era Godzilla), while Super Mechagodzilla and Kiryu can be played via selecting Defend option (where the player defends humanity as friendly kaiju such as Mothra and various G-Force Mecha). In the PS3 version, only Mechagodzilla 1975, Super Mechagodzilla, and Kiryu appear as bosses and are not playable.

The thirteenth level of ''[[City Shrouded in Shadow]]'', a game where players, as civilians, must escape and survive kaiju attacks, mostly mirrors the first encounter between Godzilla and Kiryu in ''[[Godzilla Against Mechagodzilla]]''. The protagonists, tied up in the building by Yakuza thugs, witness [[Godzilla]] rampage through the game's setting, the fictional Ichi City, and Kiryu is eventually deployed in response. After a short battle where both shoot at each other, Godzilla roars at Kiryu and reminds the spirit within of [[Godzilla (1954 film)|his past]] as a Godzilla, causing him to be possessed & go berserk. As Godzilla leaves, Kiryu approaches and fires missiles at the building in which the player is inside. Once the player has reached safety or once 30 seconds have transpired, Kiryu marches through the building, cleaving it in half, heading off into the distance. The newspaper that displays the results after the level reveals that, after 30 minutes of rampaging, Kiryu has run out of power, allowing the government to retrieve the inactive mecha.

The Shōwa, Heisei, Anime Trilogy, MonsterVerse Mechagodzilla, and Kiryu appear as playable characters in ''Godzilla Battle Line''.

Kiryu along with Godzilla, Gigan and Destoroyah become DLC guest stars in the indie game ''[[GigaBash]]''.

The MonsterVerse Mechagodzilla appears as a playable skin in [[Epic Games]]' ''[[Fortnite]]'', alongside [[Godzilla (MonsterVerse) | Godzilla]] and [[Kong (MonsterVerse) | Kong]].

===Television===
While Mechagodzilla did not appear in ''[[Godzilla: The Series]]'', a sequel to ''[[Godzilla (1998 film)| Godzilla]]'' (1998), the first Godzilla was reanimated as a cyborg called ''Cyber-Godzilla'' in the Monster Wars trilogy.<ref name="Ultimate Guide">{{cite web |url=http://www.scifijapan.com/articles/2006/03/28/godzilla-the-series/ |title=The Ultimate Guide to Godzilla: The Series|last1=Johnson|first1=Bob|last2=Aiken|first2=Keith|work=SciFi Japan|date=March 28, 2006|access-date=April 15, 2018}}</ref>

A Shōwa-inspired Mechagodzilla appears in the post-credits scene of the anime series ''[[Godzilla Singular Point]]'', though the lab's computer screens identify him as ''Robogodzilla''.

===In film===
Mechagodzilla appears in the 2018 science fiction action film ''[[Ready Player One (film)|Ready Player One]]'' where he is seen battling the [[The Iron Giant|Iron Giant]] and the [[RX-78-2 Gundam]]. This time, Mechagodzilla is remodeled and resembles the 1974 Shōwa version, the 2002 Kiryū, and the 2014 Legendary MonsterVerse Godzilla design.
