Bernie Hayes and Josh Valentine upon seeing Mechagodzilla activated (Godzilla vs. Kong)

And now... my Mecha. It's not only Godzilla's equal... but his superior. The Apex Titan of my own hand. It's time to show the world what you can do. „ 

Walter Simmons upon witnessing the full activation of Mechagodzilla (Godzilla vs. Kong)

Ha-ha-ha. „ 

— Mechagodzilla's laugh (described as warbling in the subtitles) (Godzilla vs. Kong)


Mechagodzilla is a mechanized daikaiju created by Legendary Pictures, that first appeared serving as one of the two main antagonists (alongside Walter Simmons) of the 2021 film Godzilla vs. Kong.

It was constructed by the corporation Apex Cybernetics, as an Anti-Titan weapon designed to reclaim humanity's place as the apex predator, and was innately designed to kill Godzilla. However, Apex made a mistake during its construction, using the skull of the late Ghidorah as a neural uplink and power source. This allowed the still active consciousness of Ghidorah to subsume the pilot, Ren Serizawa, and take total control. Rampaging through Hong Kong, it was eventually stopped by the combined efforts of Godzilla and Kong, before being brutally dismantled using Kong's axe.


Mechagodzilla's name comes from the word "Mecha," which is derived from "mechanical," and from another monster, Godzilla (ゴジラ,   'Gojira'?). Officially, this incarnation is called the Mecha by Apex Cybernetics, and it is christened Mechagodzilla by Josh Valentine in the film.



Mechagodzilla bears a strong resemblance to its namesake. It sports a series of short metal plates resembling Godzilla's dorsal plates (more closely resembling Godzilla's appearance from the 2014 film) running from the back of its neck all the way down to the tip of its tail. Its forelimbs are considerably bulkier and slightly longer than the real Godzilla's with four zygodactyl claws on its hands. Its feet also seem to bear a slight resemblance to Ghidorah's, while still having Godzilla's frame. Mechagodzilla's tail also has a drill mounted to its tip.


Mechagodzilla was portrayed through CGI. The only part that was portrayed in live action was the cockpit in which the pilot controls the mechanical beast. According to Krichevsky, Mechagodzilla was also portrayed via motion capture, although the actor who played him is unknown and not credited.


The MonsterVerse Mechagodzilla's roars are mostly Godzilla's roars that have been increased in pitch and edited to sound metallic. Once King Ghidorah's consciousness takes control of the mecha, it emits modified Ghidorah roars and growls which are heard during it's battles with Godzilla and Kong. Many of Mechagodzilla's sound effects originate from the Transformers live-action series, which, coincidently, was also worked on by Erik Aadahl.


Mechagodzilla is initially completely under the control of Ren Serizawa, who, using a neural interface, controls Mechagodzilla like an extension of his own body. However, once King Ghidorah's consciousness takes control of the machine, Mechagodzilla becomes incredibly violent and destructive, immediately turning on and killing its creators before bursting free from its facility. Mechagodzilla begins destroying Hong Kong before turning its attention to Godzilla, attempting to brutally kill him. It displays this same murderous intent towards Kong after the Titan intervenes. According to the filmmakers, Mechagodzilla is unique from Ghidorah, a "new consciousness" that was created when Ghidorah's personality merged with the mechanical Titan's artificial intelligence.[5]


They are building mechanized giants in Skull Island, another branch was dedicated to bioengineering mimics of other creatures.

Mechagodzilla was built in secrecy by Apex Cybernetics under the direction of their CEO Walter Simmons and their chief technology officer Ren Serizawa as a solution to the relatively powerless position humanity was in against the Titans, and moreso so that Apex could dethrone Godzilla and make themselves the architects of humanity's ascent to domination over all the other Titans. Simmons reveals that he had the idea which led to the Mechagodzilla as early as 2014 when Godzilla and the MUTOs first emerged, long before King Ghidorah caused a global Titan rampage in 2019. In order to pilot the Mecha, Apex set up the skull of Ghidorah's left head that was severed at Isla de Mara as a living supercomputer, wiring it up and taking advantage of the skull's telepathic capabilities to create a psionic uplink: the pilot would sit inside the skull and control the Mecha's actions remotely via a psionic uplink, with a piece of Ghidorah's DNA inside the actual Mecha acting as the receiver.

The first hint of the Mecha was seen in an Apex facility in Florida when Godzilla attacked the base looking for Ghidorah. When Godzilla blasted open the base with his atomic breath he unknowingly revealed a strange metal sphere which was later revealed to be one of Mechagodzilla’s eyes. Later in an enclosed Apex facility in Hong Kong, the eye was installed and the completed Mechagodzilla's might was tested against a Skullcrawler known as Number 10, with the mecha's strength and proton scream (a red energized beam) cutting through the Titan, slicing it in half, and spilling blood over a bunker. However Mechagodzilla soon shuts down as the effort drains it’s limited power supply forcing its creators to wait to hear back from the Hollow Earth expedition.

Following an excursion to the Hollow Earth, Mechagodzilla gets powered up with energy from the Earth's core. However, the energy influx prompted the remnants of Ghidorah's consciousness in the skull to override the controls, electrocuting Ren Serizawa, and killing Walter Simmons with a swipe of its hand. In the wake of the titanic conflict between Godzilla and Kong, it breaks free from its nearby facility and goes on a rampage in Hong Kong. Quickly coming into contact with Godzilla, Mechagodzilla fights its organic counterpart. Mechagodzilla manages to swiftly and brutally overpower the King of the Monsters and would have killed him if Kong had not intervened.

Despite going up against both Godzilla and Kong, Mechagodzilla manages to fight off and overpower both monsters. However, before it can kill Kong, Josh Valentine pours Bernie Hayes's alcohol onto a control panel for the mecha, causing it to hesitate for a brief moment, allowing Godzilla to charge up Kong's axe. Kong then uses his axe to brutally dismember and subsequently decapitate Mechagodzilla, ending its quite brief reign of terror.


A-74 Proton scream

Mechagodzilla's proton scream overpowers Godzilla's atomic breath.

Mechagodzilla possesses a red energy beam, capable of burning through adult Skullcrawlers, blasting through buildings immediately and knocking down as well as burning Godzilla. This beam also has the power to beam-lock with, and overpower Godzilla's atomic breath, although it should be noted Godzilla was not at full power since he had already used his atomic breath extensively to tunnel to the Hollow Earth and battle Kong.

Buzzsaw claws

Mechagodzilla is equipped with crane-like claws. The interiors of these claws are adorned with industrial buzzsaws, allowing them to cut through flesh while grappling. Mechagodzilla can even rotate its hands like drills, delivering extra damage. According to Jared Krichevski, these claws can cut through a Titan's skin and inflict massive damage.[6]

Dorsal plates

According to Jared Krichevski, Mechagodzilla's dorsal plates were used to defend any organs and making it harder for a Titan to destroy it.[6]


Being made of metal, Mechagodzilla could withstand multiple blows from Godzilla and Kong before being torn apart by Kong's powered-up battle axe.

Hollow Earth-based energy

Mechagodzilla was able to use energy from the Hollow Earth by charging it into its hands and feet, allowing it to perform devastating hits on Godzilla and Kong.

Jaw grinders

Mechagodzilla's lower jaws have a set of buzzsaws that were designed to bite down on an opponent and use the saws to cut down the flesh of said Titan's skin, inflicting massive damage.

Learning algorithms

According to the B-Roll footage for the movie, Mechagodzilla also has learning algorithms.

Missile launchers

Mechagodzilla has shoulder-mounted missile launchers capable of momentarily stunning Godzilla.

Strength and combat

Mechagodzilla knocks Godzilla down with a charged punch combined with its jet boosters.

Unlike its previous incarnations, this Mechagodzilla has enhanced physical strength and human-like reflexes that allowed it to effortlessly overpower an adult Skullcrawler, as well as knock over and throw Godzilla around. These enhanced physical attributes when combined with Mechagodzilla’s ability to charge its blows with plasma for added damage enabled it to overpower both Godzilla and Kong in the final fight, despite the mecha being outnumbered, although it must be noted that both Titans were extremely exhausted and wounded after fighting each other.


While not shown in the film, according to Jared Krichevski, Mechagodzilla's rockets could be switched to jets for underwater propulsion.[6] This ability is utilized in the film's PUBG event.

Tail drill

The drill at the end of Mechagodzilla's tail inches closer and closer to Kong's face.

Mechagodzilla's tail is equipped with a deadly drill that it attempted to use against Godzilla and Kong. When not in use, it folds into a blade remarkably similar to the one featured on the tail of the Showa incarnation of the character. This tail weapon is used to cut through any Titan’s skin and flesh straight through.


Mechagodzilla has thrusters mounted into its back and sides, enabling quick bursts of movement, or added momentum to its strikes. These thrusters can make Mechagodzilla more agile in close-quarters combat, helping it gain the upper hand against Godzilla.


Control panel damage

Any liquid poured onto Mechagodzilla's control panel resulted in it seizing up during combat, allowing Kong and Godzilla to gain the upper hand.

Energy depletion

After Mechagodzilla killed an adult Skullcrawler with its proton scream, it shuts down due to a lack of sufficient energy source. This issue, however, is resolved with the energy from the Hollow Earth.

Kong's axe

While the base form of Kong's axe didn't possess the power to grievously damage Mechagodzilla, the charged up variation was able to cleave through its armored exterior, and subsequently destroy its limbs.


  • According to writer Max Borenstein, the script he drafted for the film Godzilla: King of the Monsters originally included Mechagodzilla.[7]
  • This is the second incarnation of Mechagodzilla to be featured in an American-made film, after the RPO incarnation from Ready Player One.
  • During their Hong Kong fight, Mechagodzilla attempted to finish off Godzilla by firing its proton beam directly into Godzilla's mouth, which coincidentally was the exact same method of execution Godzilla himself used against the female MUTO in the first film.
  • Mechagodzilla is the last of the "Big Five" Toho monsters in the MonsterVerse, the others being Godzilla, Mothra, Rodan, and King Ghidorah.
  • Godzilla vs. Kong director Adam Wingard believes that Mechagodzilla's sentience when hijacked by Ghidorah's subconsciousness is the result of Ghidorah's remnant consciousness merging with the Mecha's AI to create a new personality.[8][5] The film's novelization meanwhile states when Mechagodzilla gains sentience, "It did not know who it was, or what it was, but it was full of rage and the black joy of finally being, and having limbs, and teeth, a boundless, unending energy at its command".
    • The novelization also suggests Ren Serizawa's consciousness (which here was trapped inside Mechagodzilla and devoured during the formation of Mechagodzilla's sentience, instead of being electrocuted after the psionic uplink was severed) was essentially digested to form part of the Mecha's personality.
  • According to Godzilla vs. Kong - The Official Movie Novelization, there was indeed a second Ghidorah skull of unknown origin inside Mechagodzilla and not just a piece of the Mecha's DNA, whereas the only reference to a second skull's existence in the film is Bernie Hayes speculating in regards to the skull cockpit, "there's one here, and another one inside of [Mechagodzilla]".
  • According to concept artist Jared Krichevsky who designed Mechagodzilla:
    • Mechagodzilla was designed with extra weapons and abilities that weren't shown in the film: including missile launchers in his stomach[9] and using jets in his tail to swim[6], and Jared also hoped Mechagodzilla would be able to fire a Proton Scream from his tail similar to Shin Godzilla[10].
    • Mechagodzilla's body can endure being hit by Godzilla's Atomic Breath but only for a short period of time[9][10].
    • Mechagodzilla would likely be destroyed if he battled Burning Godzilla[11].
    • Mechagodzilla could only stay active for twenty-four hours with the Hollow Earth energy[12][13].
    • He refers to Mechagodzilla with male pronouns and considers him "the son of Simmons"[14].
    • Mechagodzilla would have been much more powerful if Apex Cybernetics obtained a raw, direct sample of the Hollow Earth element and furthermore conducted proper testing on it, rather than reverse-engineering the formula and failing to perform basic testing as they did in the film[10].
    • Mechagodzilla is vulnerable to the MUTO species' EMP[10].
    • Mechagodzilla is made out of a mix of fictional metal alloys and metals which exist in real life[10].
    • If Godzilla hadn't been weakened by blasting a tunnel into the Hollow Earth and fighting Kong, then he would've been able to win in a one-on-one fight against Mechagodzilla, though "just barely"[10].
    • Mechagodzilla would have "destroyed" Kong in a fair one-on-one where both were at full strength[15].
    • Ghidorah's remains required a second brain (Ren Serizawa's) to filter its thoughts through into Mechagodzilla[13].
    • Mechagodzilla has an inbuilt self-destruct sequence in case of emergencies, which evidently wasn't activated when he went rogue[16].
  • This is the fourth Toho monster to be defeated by King Kong. It is also the second time Mechagodzilla has not been directly defeated by Godzilla, the first being during the climax of the 2018 film, Godzilla: City on the Edge of Battle, where Mechagodzilla was destroyed by Haruo Sakaki.
    • Additionally, MonsterVerse Mechagodzilla is the second mechanical monster that Kong fights and defeats, the first being Mechani-Kong in the 1967 film King Kong Escapes.
  • Mechagodzilla's appearance in Godzilla vs. Kong was said to be an "open secret" that many fans guessed before the film's premiere. The character's design was inspired by the Terminator franchise. Creature designer and concept artist explained that this meant that the design of Mechagodzilla had to be something similar to Godzilla himself, that as an intelligent animal and hunter, seeing something skeletal akin to himself would have a very unnerving effect.[17]
  • S.H.MonsterArts has released scale models for Godzilla, Kong, and Mechagodzilla. Using the scaling method, it is found that MechaGodzilla is 466 feet tall. However, his official height, according to the film's Japanese release, is actually 400 feet.[4]
  • In the mobile game PUBG, Mechagodzilla can launch his dorsal plates that would then turn into drones to attack Godzilla and Kong. These drones would operate like a hive mind with Mechagodzilla being able to control them.

References to prior Mechagodzilla incarnations

  • Mechagodzilla combines various aspects of previous incarnations such as the Showa films (villainous, has alien origins, and designed to usurp Godzilla as King of the Monsters), Heisei (has ties to an incarnation of King Ghidorah), and Kiryu (uses a bio-computer, goes berserk, and surprisingly agile). It also borrows character elements from the scrapped kaiju Berserk (taken over by some force and turning against its creators).
  • Kong decapitating Mechagodzilla is very similar to the way Godzilla twisted and ripped Mechagodzilla's head off in Godzilla vs. Mechagodzilla.
  • The idea of Mechagodzilla being controlled through a cyborg interface can be traced back to Terror of Mechagodzilla.
  • At one point, Mechagodzilla's proton scream briefly sparks with blue and yellow energy. This results in a very similar aesthetic to the space beams of the first Mechagodzilla.
  • The way Mechagodzilla is taken over by King Ghidorah's consciousness is similar to how the Heisei Mechagodzilla gets overtaken by the Mecha-King Ghidorah's programming in the manga adaptation of Godzilla vs. Mechagodzilla II.
  • Mechagodzilla gaining Ghidorah's consciousness can also be seen as a reference to the Millennium Mechagodzilla having its programming overwritten by the first Godzilla's consciousness, resulting in a rampage through the city.
  • Mechagodzilla being built around the organic components of a deceased monster was previously used in Godzilla Against Mechagodzilla.
  • Mechagodzilla's tail drill is both a reference to the Showa Mechagodzilla's unisot tail blade and Kiryu's drill hand from Godzilla: Tokyo S.O.S..
  • This Mechagodzilla's red, predominant lighting setup take cues from the anime incarnation of Mechagodzilla, which featured a strikingly similar design style during the events of Godzilla: City on the Edge of Battle.
