==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.
