History Characters / MonsterVerseMechagodzilla

* DaylightHorror: Unlike the [=MUTOs=] and Ghidorah himself in previous [=MonsterVerse=] movies, Mechagodzilla, once taken over by Ghidorah, emerges upon Hong Kong and battles Kong and Godzilla in the broad daylight of a grim, grey morning. Specifically, Mechagodzilla emerges just after dawn has broken.

* WalkingSpoiler: While its existence was spoiled by the [[invoked]][[SpoiledByTheMerchandise merchandise]] and [[TrailersAlwaysSpoil trailers]], it doesn't directly appear until relatively late in the movie, after Team Godzilla have infiltrated Apex's Hong Kong headquarters. Even then, the trailers and merch avoided showing how this version of Mechagodzilla is actually King Ghidora reborn.

* WalkingSpoiler: While its existence was spoiled by the [[SpoiledByTheMerchandise merchandise]] and [[TrailersAlwaysSpoil trailers]], it doesn't directly appear until relatively late in the movie, after Team Godzilla have infiltrated Apex's Hong Kong headquarters.

* AnArmAndALeg: Once Kong gets a second charge to his axe, he systematically dismembers Mechagodzilla limb by limb. As Kong goes for the head, all it can do is [[UndignifiedDeath scream in defiance]].

* AdaptationalAbomination: The previous three live-action Mechagodzillas were, no matter how powerful and dangerous they were, just machines. This one, however, is powered by an energy source of unknown origin and the {{Reincarnation}} of a DraconicAbomination merged with its AI and what's left of Ren Serizawa's consciousness.

* AdaptationalVillainy: [[PlayingWithATrope Played With]]. The original Mechagodzilla was built by aliens in a plot to TakeOverTheWorld and all variations since were built to combat Godzilla as a means of being humanity's best shot at protection. This version, based on the latter interpretation, was built by a NotSoWellIntentionedExtremist to wipe out or enslave the Titans, due to his warped perception of mankind relying too much on them and having no defense against the possibility of them turning against us. Even then, the previous incarnations of Mechagodzilla were only as evil as whoever was piloting them, with the closest exception being the [[Film/GodzillaAgainstMechagodzilla Millennium incarnation]] who was possessed by the original Godzilla's bones (and ultimately ended up being a hero) -- ''this'' iteration of Mechagodzilla becomes sentient due to being possessed by ''Ghidorah'''s bone, and it's evil to the end with a sadistic streak just like Ghidorah (Madison even speculates in the novelization that it would've repeated Ghidorah's attempt to wipe the world clean of life if it got the chance).

* EstablishingCharacterMoment: In its introductory scene going through a test run against a live Skullcrawler, Mechagodzilla proceeds to subdue the creature almost ''instantly'', then kills it in an excessively brutal manner pulling the Skullcrawler's arms taught to the point of breaking, and slowly cutting the helpless creature in half with the Proton Scream (and this is happening ''before'' Ghidorah's subconsciousness possesses it). It emphasizes Mechagodzilla's sheer brutality by design, and establishes that it's ''very'' powerful comparatively speaking and thus Godzilla and Kong despite themselves will not be able to put it down easily.

* EvilKnockoff: An anti-Titan HumongousMecha superweapon armed to the teeth, which has been built by [[PeaceAndLoveIncorporated Apex Cybernetics]] in Godzilla's image with the intention of murdering and replacing Godzilla as humanity's defender after a FalseFlagOperation has turned public opinion against him. Unfortunately, it [[GoneHorriblyRight works too well]] once Ghidorah's subconsciousness hijacks the system and makes the Mecha turn on its builders whilst challenging Godzilla.

* FusionDance: According to WordOfGod, Mechagodzilla's consciousness is a result of Ghidorah's consciousness in the skull merging with the Mecha's AI to create a new mind. This is supported by the novelization, which indicates that the consciousness in Mechagodzilla has GhostAmnesia and/or is an AlmightyIdiot. The novelization version of the story also hints that the mind of Ren Serizawa (who here suffers a MindReformatDeath when his consciousness becomes trapped in the Ghidorah-hijacked Mecha and drowns in its new mind) partly forms the Mecha's mind: the very moment Ren's mind fully dies is notably the exact same moment that the Mecha's own mind becomes fully realized[[note]]"The man looked back at him and smiled, then he, too, broke apart, and the thing that called himself Ren was gone, and ''it'' had arrived. 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."[[/note]].

* GoneHorriblyRight: Apex built Mechagodzilla to be an anti-Titan superweapon powerful enough to kill any Titan (including Alpha Titans) in a fight, and they designed it specifically so that they could kill Godzilla and usurp his dominance as the King of the Monsters. [[OmnicidalManiac Ghidorah]]'s consciousness or whatever's left of it in the skull could ''not'' have asked for a better machine to get hooked up to. Once said consciousness possesses Mechagodzilla, the Mecha goes on a rampage against both Godzilla and humanity, challenging the Alpha Titans (Godzilla in particular) ''exactly'' like Apex wanted it to, and threatening to implicit pick up where Ghidorah left off at creating an extinction event instead of securing Apex's world domination if the Mecha wins. In fact, Mechagodzilla's rampage after Ghidorah hijacks its AI deconstructs humanity's desire to surpass nature and build the ultimate anti-Titan weapon. You wanted the ultimate anti-Titan weapon, Apex... you got the ultimate anti-Titan weapon.

* {{Reincarnation}}: Word of God and the novelization state that Mechagodzilla is a villainous case of this trope rather than Ghidorah BackFromTheDead as an intact-minded ManInTheMachine. Director Adam Wingard has described Mechagodzilla's mind as a "new consciousness" born when Ghidorah's remnant consciousness from the skull mixed with the Mecha's AI, and the novel states Mechagodzilla "did not know who it was, or what it was, but it was full of rage and the black joy of finally ''being''". In any case, the Mecha is demonstrably [[KillAllHumans just as genocidal towards humans]] as Ghidorah ever was, and even the dead space dragon's grudge against Godzilla seems to persist in the Mecha (based on how it seeks a fight against him, and initially prioritizes targeting Godzilla over Kong), and Madison outright speculates in the novelization that the Mecha will take up Ghidorah's original goal of becoming the reigning Alpha Titan and commanding the other Titans to ravage the planet.

* RidiculouslyHumanRobot: Mechagodzilla is basically a kaiju variation. Apex were ''clearly'' trying to emulate Godzilla as much as they could when they built the Mecha; modelling it after Godzilla's signature anatomy, giving it a parallel BreathWeapon and a similar-sounding roar, and, [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3imgj/ according to Jared Krichevsky]], they even designed it to be able to swim like [[KrakenAndLeviathan Godzilla]]. Beyond this clearly reflecting Apex's hubristic desire to basically become the King of the Monsters, it's as if Apex were planning to market Mechagodzilla to the public as a new and improved Godzilla after they [[FalseFlagOperation framed the Godzilla as a monster and killed him]], the same way you'd market a new and improved vacuum cleaner model while comparing it to the old.

* StrongAndSkilled: Mechagodzilla was designed to be able to rival and attempt to surpass Godzilla in power, with a 460-foot metallic body that's armed to the teeth with the [[BreathWeapon Proton Scream]], missile launchers, thrusters, and plasma punches. It's also able to use and maneuver its body in an uncannily human-like manner, and once it gains a mind of its own, it seems to know everything about how to use its body and onboard weaponry against its foes; whilst exhibiting an almost trained-looking humanoid fighting style in close quarters (with [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3fo28/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]] commenting that the Mecha has a lot of hand-to-hand fighting moves) – this is especially impressive since the Titan which Mechagodzilla's soul originally came from was a three-headed, winged ArmlessBiped, with a ''very'' different body plan and abilities. Mechagodzilla proves to be one of the more powerful foes that both Godzilla and Kong have ever fought, coming ''very'' close to killing both of them even after they team up with each other against it (albeit partly because Godzilla and Kong were already heavily exhausted in advance of fighting the Mecha).

* WeaksauceWeakness:

** Mechagodzilla is a literal powerhouse, equipped with missile stocks and an [[BreathWeapon all-destroying lazer]], and it comes within an inch of killing an exhausted Godzilla and Kong; but, concept artist [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3m6kj/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]] believes that it would be vulnerable to an {{EMP}}. One can only imagine how ''embarrassing'' it would be for Apex if their plot to kill Godzilla had succeeded and they'd subsequently set the Mecha against [[Characters/MonsterVerseMUTO Barb the Queen MUTO]], or even if the Mecha went up against any sufficiently bio-electric Titan.

* CyberneticMythicalBeast: Right from its name, Mechagodzilla is a cybernetic Godzilla, with Kevin's skull being incorporated in its metallic head.

* TheFourthWallWillNotProtectYou: Mechagodzilla delivers his EvilLaugh while deliberately staring right at the audience.

* KickTheSonOfABitch: The first thing Mechagodzilla did upon being taken over by Ghidorah's influence is murder Walter Simmons. After he and Ren engineered a war against Godzilla that lead to likely thousands of human deaths, no one will shed tears for them.
** For that matter, Mechagodzilla electrocutes Ren to death when it breaks from his control, and as Ren was complicit in the same death toll and a dozen other crimes, no one will miss him.

!! Mechagodzilla (The Mecha)

* SpellMyNameWithAnS: The official toy merchandise spells its name as Mechagodzilla, but the film's subtitles call it Mechagodzilla.

'''[[center: [- [[Characters/MonsterVerse Main Character Index]] -]]]'''

* NoWaterproofingInTheFuture: [[DoubleSubversion Double Subverted]]. Although it's not demonstrated in the film, one of the concept artists said [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/hey_rgodzilla_jared_krichevsky_here_designer_of/gz3jhhb?utm_source=share&utm_medium=web2x&context=3 here]] that it can swim in deep waters. However, the controls to the mecha are ''not'' proofed, meaning pouring alcohol on them causes it to short-circuit.

* {{Robeast}}: Deconstructed. While designed to be the ultimate anti-Titan mech, the [[AIIsACrapshoot machine's AI goes haywire]] when Ghidorah's consciousness take control after it was infused with Hollow Earth energy, [[TurnedAgainstTheirMasters killing its creators]] and leveling a large chunk of Hong Kong before turning its attention to Godzilla. Mechagodzilla's rampage shows what happens when you put a noted omnicidal DraconicAbomination's mind into a super-powerful HumongousMecha.

* BloodKnight: {{Implied}}. As its fight against Godzilla goes on, Mechagodzilla continues pummeling him, throwing him around and brutalizing him with its bare claws and [[RocketPunch plasma punches and kicks]] whilst Godzilla can't fight back. To the point where one eventually has to wonder, how much is the Mecha drawing this out to make absolutely sure that the King of the Monsters is too weak to fight back, and how much is the Mecha doing it for the joy of making Godzilla hurt.

* ConflictKiller: {{Downplayed}}. When Ghidorah takes control and Mechagodzilla starts rampaging, it leads to the RivalsTeamUp between Godzilla and Kong to end him for good, however, he only comes in after both have had one last brawl with Godzilla being the decisive winner. He was also the entire cause of the conflict to begin with due to provoking Godzilla into attacking Apex.

* EyeColourChange: {{Downplayed}}. Mechagodzilla retains the same RedEyesTakeWarning color both when under human control and under Ghidorah's influence, but its eyes are flickering between red and white when it's in the process of being infected with whatever's left of Ghidorah's consciousness before it becomes mobile.

* ItsPersonal: {{Implied}}. When Ghidorah takes control, Mechagodzilla immediately goes after Godzilla upon singling him out in Hong Kong, with random destruction taking second priority to putting the King of the Monsters in the ground. Note that the novelization indicates the piece of Ghidorah's consciousness inside Mechagodzilla has GhostAmnesia when it first hijacks the Mecha -- the novel seems to subtly hint that Mechagodzilla's focus on killing Godzilla actually comes from Ren Serizawa's consciousness being devoured and assimilated in the Mecha.

* LivingMoodRing: Highly {{downplayed}}, but when Mechagodzilla is fully-powered and is in the process of being infected by Ghidorah's subconsciousness, its optics flicker between red and bluish-white (the only time its optics display any other color) before reverting to red. Post-sentience, the light in Mechagodzilla's optics seems to get brighter when it's particularly agitated or excited in the FinalBattle.

* NoWaterproofingInTheFuture: DoubleSubverted. Although it's not demonstrated in the film, one of the concept artists said [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/hey_rgodzilla_jared_krichevsky_here_designer_of/gz3jhhb?utm_source=share&utm_medium=web2x&context=3 here]] that it can swim in deep waters. However, the controls to the mecha are ''not'' proofed, meaning pouring alcohol on them causes it to short-circuit.

* OmnicidalManiac: {{Implied}}. It's Ghidorah {{reincarnat|ion}}ed, and its first three acts in its short life are [[TurnedAgainstTheirMasters killing its human creators]] on sight, leveling half of Hong Kong on sight, and challenging Godzilla ''on sight'' to a fight in which the Mecha almost succeeds in brutally killing the King of the Monsters. In the novelization, Madison inwardly speculates that Mechagodzilla will be ''very'' capable of taking over as the ruling Alpha after killing both Godzilla and Kong, and that it'll probably command the other Titans to essentially pick up where they left off when Ghidorah was in charge.

* RoaringRampageOfRevenge: PlayedWith. Mechagodzilla is apparently out to kill Godzilla specifically once Ghidorah takes over, and it's all too happy to slaughter any humans it sees just for the heck of it along the way. Whether this is because it remembers being killed by Godzilla and legitimately wants revenge or is just being a sadistic jackass is [[AlternativeCharacterInterpretation up for debate.]]

* RocketPunch: Downplayed. While Mechagodzilla can't detach its clawed fists as airborne rocket punches, it ''can'' supercharge its claws with blue energy (called a plasma punch according to [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3lrs5/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]]) to add a devastating extra kick to its punches. And it can do this ''while'' using the propulsors on its back [[JumpJetPack to increase its forward momentum]].

* ThisIsADrill: Downplayed. One of Mechagodzilla's many inbuilt weapons is the forked blade [[BewareMyStingerTail on the tip of its tail]], which it can unfold into a four-pronged claw that rapidly rotates like a drill for the purpose of tearing and burrowing into Titans' bodies. Mechagodzilla briefly attempts to deploy this weapon against Godzilla when it has him pinned against a building, before Kong stops it, then it almost ''succeeds'' in driving this weapon into Kong's skull when it has ''him'' pinned.

* WetwareCPU: PlayedWith. Mechagodzilla is supposed to be operated by a human controller through a cybernetic interface. However, when Mechagodzilla is activated, the human operator is rapidly disposed of, and Mechagodzilla goes on a rampage through Hong Kong. Why? Because Mechagodzilla is actually being controlled by what's left of Ghidora. So Mechagodzilla is in fact being controlled by an organic mind -- just not the entity that its builders thought would be in control.

* WorldsBestWarrior: ZigZagged. InUniverse, it was specifically designed by Apex to be able to defeat Godzilla in a fight. While it does become the only being seen thus far capable of absolutely dominating Godzilla once Ghidorah takes it over, WordOfGod and the novelization both suggest that Godzilla would've not done as badly in a fair fight, and perhaps would've won on his own if he wasn't already heavily weakened beforehand. Mechagodzilla also notably struggles more when fighting Kong than it does when fighting Godzilla, even if it does eventually get the upper-hand against the ape (and only fails to drive its tail drill into Kong's skull thanks to Team Godzilla disrupting the Mecha's satellite link) even though Kong is roughly as exhausted as Godzilla; indicating the Mecha was specialized for fighting ''Godzilla'' specifically.

* RoaringRampageOfRevenge: PlayedWith. Mechagodzilla is apparently out to kill Godzilla specifically once Ghidorah takes over, and it's all too happy to slaughter any humans it sees just for the heck of it along the way. Whether this is because Ghidorah remembers being killed by Godzilla and legitimately wants revenge or is just being a sadistic jackass is [[AlternativeCharacterInterpretation up for debate.]]

* RoaringRampageOfRevenge: PlayedWith. Mechagodzilla is apparently out to kill Godzilla specifically once Ghidorah takes over, and it's all too happy to slaughter any humans it sees just for the heck of it along the way.

* NewTechIsNotCheap: It's one of the largest and most powerful superweapons mankind has ever developed, it guzzles so much energy that it's literally impossible for its builders to keep it running for more than a couple minutes at a time, and [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3ey6n/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]] estimates that Apex spent approximately three ''''TRILLION'''' US dollars on it.

* KillAndReplace: What Madison stated to Josh and Bernie in the Apex Facility after witnessing Mechagodzilla slaughtering #10, Apex intentionally crafted him to destroy Godzilla just to prove that [[HumansAreBastards humans are the dominant species]] as well as replacing him entirely via usurpation.

* NewTechIsNotCheap: It's one of the largest and most powerful superweapons mankind has ever developed, it guzzles so much energy that it's literally impossible for its builders to keep it running for more than a couple minutes at a time, and [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3ey6n/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]] estimates that Apex spent approximately three trillion US dollars on it.

* EffectiveKnockoff: He's built in Godzilla's image, and he fully overpowering the former in a straight fight, something that no other incarnation of Mechagodzilla has ever accomplished (although Word of God says the two would've been on much more equal footing and Godzilla would have likely won by himself if the latter wasn't severely exhausted from boring a hole to the HollowEarth and dueling Kong).

* NoWaterproofingInTheFuture: DoubleSubverted. Although it's not demonstrated in the film, one of the concept artists said [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/hey_rgodzilla_jared_krichevsky_here_designer_of/gz3jhhb?utm_source=share&utm_medium=web2x&context=3 here]] that it can swim in deep waters. However, [[spoiler:the controls to the mecha are ''not'' proofed, meaning pouring alcohol on them causes it to short-circuit]].

* AdaptationDyeJob: In the Toho films, [=MechaGodzilla's=] mechanical glowing eyes in each of their respective appearances are usually depicted as a brightened yellow, along with having a slight shade of orange into the mix. This one's eyes are nothing but an eerie red similar to Kiryu's berserk mode. And just like Kiryu, it goes rogue by proceeding to destroy a city while under the control of a deceased kaiju from the skeletal remains.

* FullConversionCyborg: Much like Kiryū from ''Film/GodzillaAgainstMechagodzilla'' and ''Film/GodzillaTokyoSOS'', Mechagodzilla is an anti-kaiju mech, which looks completely robotic on the surface but has actually been made by integrating organic kaiju matter (a piece of Ghidorah's DNA in this case acting as a receiver for the BrainComputerInterface in San/Kevin's skull). This organic matter eventually seizes control of the mech's systems and causes it to rampage. It's speculated by Bernie in the movie, and explicitly confirmed in the novelization, that there was an entire second Ghidorah skull inside the Mecha, [[AdaptationInducedPlotHole but neither version of the story explains where the hell a second skull could have come from]] after [[NotEnoughToBury the manner in which Ghidorah died]] during the previous movie.
* FusionDance: According to Word of God, Mechagodzilla's consciousness is a result of Ghidorah's consciousness in the skull merging with the Mecha's AI to create a new mind. This is supported by the novelization, which indicates that the consciousness in Mechagodzilla has GhostAmnesia and/or is an AlmightyIdiot. The novelization version of the story also hints that the mind of Ren Serizawa (who here suffers a MindReformatDeath when his consciousness becomes trapped in the Ghidorah-hijacked Mecha and drowns in its new mind) partly forms the Mecha's mind: the very moment Ren's mind fully dies is notably the exact same moment that the Mecha's own mind becomes fully realized[[note]]"The man looked back at him and smiled, then he, too, broke apart, and the thing that called himself Ren was gone, and ''it'' had arrived. 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."[[/note]].

** This version of Mechagodzilla is hit with a dose of reality, in that its systems and weapons use ''so much'' power that there literally isn't any power source in mankind's possession that can give the Mecha more than a couple minutes of power before being sucked dry (and even then, the Mecha's Proton Scream only works at 40% power during this time). Apex successfully get around this by infusing Mechagodzilla with a synthesized copy of the HollowEarth[='s=] energy source, which enables the Mecha to operate at full power seemingly indefinitely, [[EvilIsNotAToy albeit with some unexpected side effects]].

* RoarBeforeBeating: He lets out a low, grating roar just before he charges into battle against Godzilla, once Godzilla has started charging for the kill towards him after they've singled each-other out.

* RoboticPsychopath: Given he's possessed by ''King Ghidorah'', this is no surprise. Whether Ghidorah is completely in control or not, [=MechaGodzilla=] levels a large portion of Hong Kong and ''laughs'' about it before trying to brutally beat Godzilla to death.
* RocketPunch: Downplayed. While Mechagodzilla can't detach its clawed fists as airborne rocket-punches, it ''can'' supercharge its claws with blue energy (called a plasma punch according to [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3lrs5/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]]) to add a devastating extra kick to its punches. And it can do this ''while'' using the propulsors on its back [[JumpJetPack to increase its forward momentum]].

* SpellMyNameWithAnS: The official toy merchandise spells its name as [=MechaGodzilla=], but the film's subtitles call it Mechagodzilla.
* StrongAndSkilled: Mechagodzilla was designed to be able to rival and attempt to surpass Godzilla in power, with a 460-foot metallic body that's armed to the teeth with the [[BreathWeapon Proton Scream]], missile launchers, thrusters and plasma punches. It's also able to use and maneuver its body in an uncannily human-like manner, and once it gains a mind of its own, it seems to know everything about how to use its body and onboard weaponry against its foes; whilst exhibiting an almost trained-looking humanoid fighting style in close quarters (with [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3fo28/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]] commenting that the Mecha has a lot of hand-to-hand fighting moves) – this is especially impressive since the Titan which Mechagodzilla's soul originally came from was a three-headed, winged ArmlessBiped, with a ''very'' different body plan and abilities. Mechagodzilla proves to be one of the more powerful foes that both Godzilla and Kong have ever fought, coming ''very'' close to killing both of them even after they team up with each-other against it (albeit partly because Godzilla and Kong were already heavily exhausted in advance of fighting the Mecha).

* ThisIsADrill: Downplayed. One of Mechagodzilla's many inbuilt weapons is the forked blade [[BewareMyStingerTail on the tip of its tail]], which it can unfold into a four-pronged claw which rapidly rotates like a drill for the purpose of tearing and burrowing into Titans' bodies. Mechagodzilla briefly attempts to deploy this weapon against Godzilla when it has him pinned against a building, before Kong stops it, then it almost ''succeeds'' in driving this weapon into Kong's skull when it has ''him'' pinned.

* NoWaterproofingInTheFuture: {{Averted}}. Although it's not demonstrated in the film, one of the concept artists said [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/hey_rgodzilla_jared_krichevsky_here_designer_of/gz3jhhb?utm_source=share&utm_medium=web2x&context=3 here]] that it can swim in deep waters.

* JaggedMouth: Type 2. Mechagodzilla's jaws are mostly straight-angled and cuboid, except they have struts built into them which give the illusion that Mechagodzilla has jagged teeth at a distance, and the Mecha very much ends up being a vessel for evil rather than good. And that's not even getting into the ''actual buzzsaws'' that the Mecha's jaws conceal.”), JumpJetPack(“It has six rocket thrusters built into its back, which allow it to jump or sprint forward with increased speed and momentum for its size and weight.

* MonsterMouth: Mechagodzilla has intimidating-looking {{jagged jaws}}, which themselves contain ''rows of buzzsaws'' designed to violently tear through the hide of any Titan that Mechagodzilla bites down on (although we never see the Mecha using them in combat).

* SelfDestructMechanism: According to [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/hey_rgodzilla_jared_krichevsky_here_designer_of/gz7l3mj?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]], Mechagodzilla has an emergency self-destruct sequence, but it obviously didn't deploy when Ghidorah's subconsciousness overtook the Mecha and [[TurnedAgainstTheirMastrs it went murderously rogue]].

* BewareMyStingerTail: It has a blade on the tip of its tail that can be rotated like a drill and used when its limbs are incapacitated or occupied.

* MacrossMissileMassacre: It just wouldn't be Mechagodzilla without mounting more missiles than a regiment of [[TabletopGame/BattleTech BattleMechs]]. The Mecha opens with a Salvo that even Godzilla can't just shrug off.

* RidiculouslyHumanRobot: The Kaiju counterpart. Mechagodzilla emulates Godzilla in appearance but was never meant to be anything more than a puppet for Apex Cybernetics. That all changes when they decide to integrate Ghidorah's neurons into Mechagodzilla's circuitry, allowing whatever remained of Ghidorah's intelligence to take over and wreak havoc in Hong Kong.

* RocketPunch: Downplayed. While Mechagodzilla can't detach its clawed fists as airborne rocket-punches, it ''can'' supercharge its claws with blue energy (called a plasma punch according to [[https://www.reddit.com/r/GODZILLA/comments/niq8wk/comment/gz3lrs5/?utm_source=share&utm_medium=web2x&context=3 Jared Krichevsky]]) to add a devastating extra kick to its punches. And it can do this ''while'' using the propulsors on its back to increase its forward momentum.

* WeaksauceWeakness: Even after Ghidorah's influence turns Mechagodzilla into an indiscriminate killing machine, the Mecha is still reliant on its satellite link to function. Its ultimate undoing: Josh spilling a flask of liquor into the vents of Apex's control panel, interrupting the link and causing Mechagodzilla to seize up momentarily, providing just the momentary leeway that Kong and Godzilla need.

* CurbStompCushion: Kong stops it delivering the final blow to Godzilla, and the Mecha is outmatched by the combined might of Godzilla and Kong, though only barely. Mechagodzilla still holds the upper hand for much of the fight, and it could very well have killed them both if it wasn't momentarily stalled due to Josh disrupting its satellite uplink systems.
