History Characters / ArmoredCoreVIEnemiesAndBosses

* WeaksauceWeakness: Using “pop up” tactics by using high-damage, long reload weapons such as the Bazooka or the later grenade launcher, as well as the eight cell missile launchers and standing on a side platform will allow you to easily annihilate by simply popping up with your jets, firing off a salvo, and then ducking into cover as it fires back.

* FutileHandReach: Performs one of these towards the player as it dies.

* DefiantToTheEnd: In direct contrast to Ayre's FutileHandReach at the end of the battle, Iguazu attempts a last ditch effort to kill you by lunging at you with his claw active, only to be denied by the SOL 644's destruction as he admits that he ultimately envied the freelancer.

* WeakSauceWeakness: [[spoiler:Using “pop up” tactics by using high-damage, long reload weapons such as the Bazooka or the later grenade launcher, as well as the eight cell missile launchers and standing on a side platform will allow you to easily annihilate by simply popping up with your jets, firing off a salvo, and then ducking into cover as it fires back.]]

* Recurring Element: The EKDROMOI are the latest in a long line of [[DualBoss dual boss]] fights with opponents that complement each other's strengths and weaknesses that was started all the way back in ''[[VideoGame/DarkSouls Dark Souls]]'' with Ornstein and Smough. The EKDROMOI EP uses its energy blade and bigger health bar to fight you at close range, while the EKDROMOI PC hangs at the back and prefers to support its fellow EKDROMOI with suppressing fire.

[[folder:[=AH12=] HC Helicopter]]
!![=AH12=] HC Helicopter

* RecurringBoss: [[spoiler:A second Helicopter makes a surprise appearance at the end of "Survey the Uninhabited Floating City", alongside some backup. Thankfully, 621 and Ayre can also hack into the inactive drones in Xylem to get help of their own.]]

[[folder:[=AAP07=] Balteus]]

* AttackDrone: The Balteus is an autonomous combat craft.

* RecurringBoss: [[spoiler:After the fight, the Balteus's wreck is salvaged by Arquebus, who begin rebuilding it into the manned AC [=AAP07A=] Arquebus Balteus; the finished product is fought during the "Liberator of Rubicon" ending path, where it's manned by V.II Snail and trades its conventional weaponry for Arquebus' energy weaponry, thus sporting a new moveset (notably lacking its missile racks and flamethrower).]]

* MeaningfulName: "Balteus" is the plural form for a belt Roman soldiers hung their swords from. The Balteus likewise is encircled with weapon racks that fire {{Macross Missile Massacre}}s ''at minimum''.
* MechaExpansionPack: The Balteus is an AC suspended in a large, flight-capable weapons platform.

[[caption-width-right:1000:When the PCA really wants you dead]]

* RecurringBoss: Aside from their appearance as the bosses of "Attack the Refueling Base", [[spoiler:a pair of those, together with a CATAPHRACT, serve as the bosses of "Obstruct the Mandatory Inspection"]].

[[folder:[=AAP03=] Enforcer]]

* HumongousMecha: In a game full of ten-metre-tall humanoid combat robots, the Enforcer stands out by being at least twice the size of anything the player can field.
* JackOfAllStats: As far as ''Armored Core'' bosses go, the Enforcer is pretty run-of-the-mill. It has access to a decent selection of ranged and melee attacks, but has no special gimmicks to look out for. On the flipside, it leaves few glaring flaws in its design that can be easily exploited by the player.
* LightningBruiser: Not only does it hit like a freight train, it's almost as agile as an enemy AC (though nowhere near as fast as the Balteus).
* ShockwaveStomp: Once it TurnsRed, one of its new attacks is to leap into the air and do a SwordPlant with its laser blade that sends a shockwave of energy bursting out from around it. [[spoiler:You can avoid it by taking to the air, or navigating around to the Enforcer's rear.]]
* TransformingMecha: When you first encounter it blowing away Balam's soldiers, the Enforcer's in a configuration that makes it resemble a SpiderTank. When you finally corner it at the end of the stage, it transforms into "Termination Mode" to do battle with you.

[[folder:[=EB-0309=] Strider]]

The "crowning glory" of the Rubicon Liberation Front's militarization efforts, the Strider is a gigantic mining and resource base that's been weaponized, particularly with the installation of the Eye, a large laser cannon.

* AttackItsWeakPoint: The Strider is broken down into five soft spots that have to be destroyed before taking on the Eye itself: one of its legs and four sub-generators that power the Eye's DeflectorShields.
* AwesomeButImpractical: While the Strider ''looks'' imposing and has a fearsome long-range gun, it's still an industrial craft trying to do something it's not built to do. It's slow, full of obvious weak spots and its main weapon is easily dodged by a brain-fried AC pilot. It's telling that 621 is able to momentarily cripple the gigantic vehicle merely by shooting ''one'' of its legs thanks to how poor its condition is.
* BaseOnWheels: The Strider is what you get when you upsize a SpiderTank until it becomes a battleship with turrets of all shapes and sizes.
* ColossusClimb: After causing the rearmost section of the Strider to crash, 621 jumps aboard and starts jumping around its sides in order to reach its sub-generators while the rest of it keeps walking acros the desert.
* CorridorCubbyholeRun: While traversing the Strider's body, the Eye is still actively targeting and firing on you, forcing players to find cover to avoid getting their AP melted away while trying to reach each sub-generator.
* {{Expy}}: With its design as a giant walking weapons platform, along with an initial approach sequence where the player has to dodge incoming fire, the Strider comes across as a poor man's version of [[VideoGame/ArmoredCoreForAnswer The Spirit of Motherwill]].

* LevelInBossClothing: Given how huge it is, the majority of the Strider's body is more of a platforming challenge that builds up to the actual boss fight against the Eye itself, which contains most of the Strider's health pool.

* PaperTiger: The fight against the Strider illustrates how out of their depth the RLF is. Their most impressive weapon is treated with contempt by Arquebus, who mostly consider it a nuisance to their Coral surveys. 621, a single no-name mercenary, destroys it before they've even finished half of Chapter 1.

[[folder:[=HA-T-102=] Juggernaut]]

* AttackItsWeakPoint: True to its name, Juggernaut's thick frontal armor makes head-on attacks ineffective, requiring the player to get around it.

* PlayerNudge: V.IV Rusty [[GuestStarPartyMember helps out]] early in the fight, and tells the player to hit Juggernaut's sides and rear while he plays bait. After he's called away, the player has to then use that strategy without a decoy.
* RammingAlwaysWorks: Juggernaut will take advantage of its weight, armored prow, and rocket boosters to charge down your AC.
* TankGoodness: Juggernaut's a tracked vehicle that stands twice as tall as an AC.
* TurnsRed: Damage Juggernaut enough and it starts dropping land mines around it.
* WeaksauceWeakness: Juggernaut carries lots and lots of ranged weapons and makes standing in its front arc very dangrous, but it has almost nothing for close-in defense, meaning that it's almost incapable of attacking anything that's standing directly on top of it. Jumping on top of it, then using your pulse sword to greatly damage its ACS system in two strikes and firing away as its damage will allow you to beat him, as the pulse sword’s following system will allow you to track the boss even if it fires jet thrusters.

[[folder:[=EC-0804=] Smart Cleaner]]

* AttackItsWeakpoint: The Smart Cleaner's only unarmored parts are the large furnace on its top or the opening at its front.
* ImprovisedWeapon: Much like the rest of [=RaD=]'s handiwork, the Smart Cleaner is an industrial machine converted for combat, albeit without much in the way of extra weaponry other than its furnace and scrap crushers.

* RecurringBoss: [[spoiler:A second Smart Cleaner appears on the Xylem during the Liberator of Rubicon story branch.]]

* {{Foreshadowing}}: An Institute's weapon that suddenly appears to attack 621 once they managed to evade the firing range of the PCA Outer Shell Security laser satellites, with Carla wondering what is one doing here. It's the first hint that the PCA have direct control of several C-Weapons that they will use to eliminate problematic individuals, like the Ice Worm later on that is also sicced on 621.

[[folder:[=IA-02=] Ice Worm]]
Another Coral-powered C-Weapon left behind by the Institute, the Ice Worm is a gigantic tunneling machine that suddenly appears after 621 and Rusty just took down the PCA's berthed warship fleet. It serves as the Final Boss of Chapter 3.

* ClimaxBoss: The Ice Worm is a titanic, worm-like behemoth of a machine that's fought in an epic battle against you and your allied [=ACs=], it's fought at least 2/3rds through the game, and its defeat results in [[spoiler:Ayre [[TheReveal revealing]] that The Coral are not just [[StarfishAliens an alien species]]; she is one of them.]]
* DeflectorShields: The Ice Worm's body is completely impervious to damage, and its sole weakpoint - its maw - is covered by two layers of shielding that can only be broken with specialized weaponry, and even then only for a brief time.

* GodzillaThreshold: Once 621 managed to wipe out all the PCA's berthed warships at the Old Bertram Spaceport, then take out the reinforcements of more warships and [[DualBoss HC and LC units]] and is identified as a threat to planetary closure, the Ice Worm is authorized for use and sicced on 621 to eliminate them once and for all.

* ImprobableAimingSkills: It's the target of them, courtesy of Rusty [[spoiler:shooting it repeatedly with a humongous stationary cannon that's installed ''on another continent'']]. This would be impressive already against a stationary target, but the Ice Worm is of course moving around the whole time, most of it underground, making this a downright superhuman feat of marksmanship.

* TimeLimitBoss: While there's no explicit timer, Rusty's railgun only has a limited number of shots, and the Ice Worm is capable of recovering its Coral shield even after the last one. If you haven't killed it by the time it does so, [[NonStandardGameOver the mission fails,]] since there's no way to bring it back down.

* GoodColorsEvilColors: [[InvertedTrope A rare inversion]]. The original SOL 644 glows bright red, usually a ''villainous'' color, and uses red energy in all of its attacks, but it is controlled by your former friend [[HeroAntagonist Ayre]] and tries to stop you from condemning all of Rubicon, humans and Coral alike, to fiery destruction. The modified SOL 644 instead utilizes bright blue or bluish green, which are usually ''heroic'' colors, but is piloted by either the rogue A.I. [[WellIntentionedExtremist ALLMIND]] [[DeathOfPersonality trying to assimilate you]] or the violent and near insane [[GreenEyedMonster Iguazu]] [[TheBerserker trying to rip you to shreds]], and tries to dispose of you either way.

* GoodWeaponEvilWeapon: [[InvertedTrope A rare inversion]]. The original SOL 644 glows bright red, usually a ''villainous'' color, and uses red energy in all of its attacks, but it is controlled by your former friend [[HeroAntagonist Ayre]] and tries to stop you from condemning all of Rubicon, humans and Coral alike, to fiery destruction. The modified SOL 644 instead utilizes bright blue or bluish green, which are usually ''heroic'' colors, but is piloted by either the rogue A.I. [[WellIntentionedExtremist ALLMIND]] [[DeathOfPersonality trying to assimilate you]] or the violent and near insane [[GreenEyedMonster Iguazu]] [[TheBerserker trying to rip you to shreds]], and tries to dispose of you either way.

* AceCustom: It's all but outright stated that this hulking AC is actually the SOL 644, the FinalBoss of the “Fires of Raven” route, after heavy modification and refurbishment to suit ALLMIND's tastes. As a result of being controlled by It sacrifices a lot of its abilities in that route, such as its missiles, pulse armor, DoppelgangerAttack, and the ability to transform into a birdlike configuration and fly around the arena, but gains a lot of new ones here, such as souped up blast attacks, massive WolverineClaws, the ability to control other machines outside of it (hence the two SEA SPIDERS), and the ability to fire massive lasers.
* CurbStompBattle: If the sheer speed of their shock at its arrival and how fast ALLMIND responds that both have been dealt with mere seconds after C4-621 regains control of the ship they commandeered is any indication, ALLMIND inflicted this on both "Cinder" Carla and Walter's HAL 826, which is noteworthy as the HAL 826 is the Final Boss in the "Liberator of Rubicon" ending and is no slouch in a fight himself.
* DarkIsEvil: Instead of the gleaming white of the original SOL 644 and even the slightly darker silver of its predecessors, the modified SOL 644 here is a very dark grey that almost borders on black in some shots. And while “evil” is a ''huge'' stretch and [[WellIntentionedExtremist may not even be applicable to ALLMIND]], the bloodlusted and enraged GreenEyedMonster Iguazu ''definitely'' qualifies, especially when he pulls a VillainOverride on ALLMIND in the later stage of their boss fight.

* LightningBrusier: Exactly as hulking and powerful as the original SOL 644 and exactly as agile, too. At least it doesn't have the Pulse Armor this time around, but that's hardly a consolation with its beefed-up moveset and the two SEA SPIDERS that fight alongside it.

!!ALLMIND

[[folder:[=IA-13=] Sea Spider]]

A relic from before the Fire of Ibis, the Sea Spider is a "C-Weapon" that was developed by the Rubicon Research Institute. It suddenly appears to attack C4-621 while they try to board a cargo launcher to reach the Ice Fields across the ocean.

* RecurringBoss: [[spoiler:During the final boss fight of the GoldenEnding, ALLMIND summons two second phase Sea Spiders to assist it.]]

* GoodWeaponEvilWeapon: Playing the role of a HeroAntagonist, it uses a [[HeroesPreferSwords sword]] for melee options. [[spoiler: While piloted by Iguazu and ALLMIND, it instead uses the sinister-looking [[WolverineClaws claws]] and a pitchfork-like trident.]]

The FinalBoss of the Alea Iacta Est path. After defeating MIND GAMMA in the first phase, ALLMIND calls in three heavily modified C-Weapons, one of which was originally SOL 644.

* AceCustom: It's all but outright stated that the mech ALLMIND uses in the second phase is heavily a modified SOL 644. It has different abilities such as souped-up blast attacks, massive WolverineClaws, two Sea Spiders backing it up, and the ability to fire massive lasers.

* DarkIsEvil: ALLMIND's mechs sport a very dark grey that almost borders on black in some shots. [[WellIntentionedExtremist Well-intentionedness]] of ALLMIND aside, Iguazu ''definitely'' qualifies, especially when he pulls a VillainOverride on ALLMIND in a later stage of their boss fight.

* ExtraEyes: Initially appearing faceless when first encountered, it opens its face to reveal seven bluish-green eyes spaced evenly around the center, similar to its original counterpart.
* LightningBruiser: As hulking and powerful as the original SOL 644 and as agile. Though, unlike

* TurnsRed: After getting knocked down to half health, Iguazu unleashes a massive energy wave that disables both Ayre's ECHO and ALLMIND's control over it in addition to the Sea Spiders it summoned for the fight, and then goes ''absolutely bonkers'' on you, trying to charge at you and tear you to shreds with its massive WolverineClaws, as an indication of Iguazu's current mental state.
* WolfpackBoss: It is assisted by two second-phase Sea Spiders at the beginning of the fight, though thankfully you have your ally in Ayre and they get disabled when Iguazu forces ALLMIND out of SOL.
* WolverineClaws: Its most defining feature is the three massive energy blades it unfolds from each hand in the later stage of its fight, which slashes rapidly at you in a manner very reminiscent of the claws of an animal.

[[folder:'''The Final Boss''']]

* CurbStompBattle: [If the sheer speed of their shock at its arrival and how fast ALLMIND responds that both have been dealt with mere seconds after C4-621 regains control of the ship they commandeered is any indication, ALLMIND inflicted this on both "Cinder" Carla and Walter's HAL 826, which is noteworthy as the HAL 826 is the Final Boss in the "Liberator of Rubicon" ending and is no slouch in a fight himself.

* TheWorfEffect: In Alea Iacta Est, ALLMIND [[CurbStompBattle crushes him]] just before the final battle, as you can see the remains of the HAL 625 at MIND GAMMA's feet.

The FinalBoss of the [[spoiler:Fires of Raven]] path. It is [[spoiler:an extrasolar and even more advanced Ibis-series AC that Ayre directly pilots against you to stop you from igniting a second Fires of Ibis, which would result in the deaths of millions and the extinction of her entire species.]]

* ApologeticAttacker: Its combat dialogue makes it very clear that it does not want to fight you, but has no other choice.

* LightningBruiser: While it's just as agile as the first Ibis you fight, it's significantly sturdier, thanks to thicker plating and powerful resummonable Pulse Armor. Your only saving grace is that it doesn't get up after you down it the first time.

* WeUsedToBeFriends: This Ibis-series AC is piloted by [[spoiler:Ayre, the only character in the game that had been nothing but nice and supportive of you from the moment you met. And you betrayed her, forcing her to commandeer an AC to try and stop you personally from wiping out her entire species.]]

The FinalBoss of the [[spoiler:Liberator of Rubicon]] path. It is [[spoiler:the only one of the Ibis-series Cores stored beneath Watchpoint Alpha to be designed to accommodate a human pilot, meaning that it ends up as Handler Walter's personal machine - either as a BrainwashedAndCrazy puppet of Arquebus in the Liberator of Rubicon route, or as his normal WellIntentionedExtremist self in Alea Iacta Est after the chaos you and ALLMIND created gave him and the rest of OVERSEER a clear shot at the Institute's treasures.]]

* EvilMentor: [[spoiler:The pilot controlling this monster is none other than Handler Walter.]]
* GettingSmiliesPaintedOnYourSoul: [[spoiler:Mere moments before chapter 5 stars, Walter gets captured by Arquebus Group for re-education. When you fight him in the Liberator of Rubicon ending, it's obvious that whatever Arquebus did to him, he's not entirely himself anymore and his motivations tend to switch between worshipping Arquebus and wanting to honor the legacy of his friends. Somewhat {{Downplayed}} given the ending that he's fought in has the player explicitly go against that legacy, meaning Walter would have had reason to oppose the player regardless.]]

* UnusableEnemyEquipment: The AC isn't available until NewGamePlus after completing [[spoiler:the "Liberator of Rubicon" path]]. Although weaker in comparison to its boss battle, the HAL 826 has great stats across the board and is otherwise one of the best units you can craft in the game barring meta and MinMaxing builds.
* UnwillingRoboticisation: [[spoiler:Handler Walter fights you after being captured by VII. Snail (whose Arena description helpfully informs the player that Snail likes to constantly tweak his augmentations and test them out on others). His demeanor during the fight indicates that it's done a number on his mind, with Walter noticably having trouble forming full sentences.]]

[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/ac6_strider.jpg]]
[[caption-width-right:1000:Cornerstone of the RLF's arsenal]]

The "crowning glory" of the Rubicon Liberation Front's militarization efforts, the Strider is a gigantic mining and resource base that's been weaponized, particularly with the installation of the Eye, a large laser cannon.

* ImprovisedWeapon: The RLF are trying to turn a civilian mining base into a weapons platform, to mixed results.
* LevelInBossClothing: Given how huge it is, the majority of the Strider's body is more of a platforming challenge that builds up to the actual boss fight against the Eye itself, which contains most of the Strider's health pool.
* MortonsFork: If you agree to destroy it, it... [[ShapedLikeItself gets destroyed]]. [[spoiler:If you agree to defend it, it gets destroyed even faster (before you even reach it), your mission objective switches to finding out just who or what took it down, and [[BlamedForBeingRailroaded you get hit with a massive fine for failing your contract]].]]
* PaperTiger: The fight against the Strider illustrates how out of their depth the RLF is. Their most impressive weapon is treated with contempt by Arquebus, who mostly consider it a nuisance to their Coral surveys. 621, a single no-name mercenary, destroys it before they've even finished half of Chapter 1.

[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/ac6_juggernaut.jpg]]
[[caption-width-right:1000:The Wall's last line of defense]]

A gargantuan mobile weapons platform and the primary objective of Operation Wallclimber.

* AttackItsWeakPoint: True to its name, Juggernaut's thick frontal armor makes head-on attacks ineffective, requiring the player to get around it.
* BackgroundBoss: It's actually visible at the start of the level- it's the "artillery piece" perched at the very top of the wall lobbing explosive shells at you as you approach the wall.
* LightningBruiser: It's the size of a building but is very capable of keeping up with an AC, thanks to its rocket boosters.
* MacrossMissileMassacre: one of its weapons is a swarm of missiles aimed right at you.
* NitroBoost: Is covered in rocket thrusters that it will use to not only charge enemies, but also to quickly reverse or turn around.
* PlayerNudge: V.IV Rusty [[GuestStarPartyMember helps out]] early in the fight, and tells the player to hit Juggernaut's sides and rear while he plays bait. After he's called away, the player has to then use that strategy without a decoy.
* RammingAlwaysWorks: Juggernaut will take advantage of its weight, armored prow, and rocket boosters to charge down your AC.

[[quoteright:1000:[[labelnote:[[spoiler:Second appearance.]]]]https://static.tvtropes.org/pmwiki/pub/images/ac6_arquebus_balteus.jpg [[/labelnote]]]]

An autonomous PCA attack craft, menacing C4-621 after the attack on the Watchpoint.

* AchillesHeel: Its shields take increased damage from pulse weapons, which you unlock before fighting it - this goes double since breaking its shields puts it in a staggered mode letting you capitalize on the damage. Secondly, while its missile attacks are effective - it needs to come to a full stop to launch them therefore giving you a good window of opportunity to blast it with heavier weapons.
* AttackDrone: The Balteus is an autonomous combat craft.
* BrokenArmorBossBattle: A good part of the fight is destroying its [[DeflectorShields Phase armor]] to cause actual damage.
* DeflectorShields: It's protected by Pulse Armor, requiring you to break it before you can work on its health bar.
* LightningBruiser: It's ''fast'', to the point where even high-speed [=ACs=] can struggle to keep up with it, and it can and will turn an AC to scrap in seconds.
* RecurringBoss: [[spoiler:After the fight, the Balteus's wreck is salvaged by Arquebus, who begin rebuilding it into the manned AC [=AAP07A=] Arquebus Balteus; the finished product is fought during the "Liberator of Rubicon" ending path, where it's manned by V.II Snail and trades its conventional weaponry for Arquebus' energy weaponry, thus sporting a new moveset (notably lacking its missile racks and flamethrower).]]
* MacrossMissileMassacre: Emphasis on "massacre," with it capable of launching both a tight cloud of homing missiles or an orb-shaped sphere of heat-seeking death.
* MeaningfulName: "Balteus" is the plural form for a belt Roman soldiers hung their swords from. The Balteus likewise is encircled with weapon racks that fire {{Macross Missile Massacre}}s ''at minimum''.
* MechaExpansionPack: The Balteus is an AC suspended in a large, flight-capable weapons platform.
* TurnsRed: At roughly half health, it unleashes an [[SphereOfDestruction Assault Armor burst]], and then breaks out its flamethrowers, changing up its attack patterns with swipes of hot fiery wrath.
* WalkingArmory: It's packed to the gills with hot leaden death, including [[MacrossMissileMassacre clouds of missiles]], a heavy artillery cannon, shotgun blasts, a rapid-fire autocannon, and dual flame emitters that double as [[FlamingSword flaming blades]] or a [[FireBreathingWeapon massive flamethrower.]]
* WakeUpCallBoss: The boss of Chapter 1, and it ''will'' make sure that you know the ins and outs of the game cold before you go any further.

[[caption-width-right:1000:When trash disposal involves mechas]]

An autonomous industrial robot built for large-scale structural disassembly and scrap recycling, repurposed by [=RaD=] into a formidable combat unit.

* AttackItsWeakpoint: The Smart Cleaner's only unarmored parts are the large furnace on its top or the opening at its front.
* ImprovisedWeapon: Much like the rest of [=RaD=]'s handiwork, the Smart Cleaner is an industrial machine converted for combat, albeit without much in the way of extra weaponry other than its furnace and scrap crushers.
* IronicNickname: Almost certainly one of Cinder Carla's in-jokes, its name makes it sound like a glorified Roomba... which it basically is, if that Roomba was the size of a 20-story building and designed to "clean" the carcasses of long-abandoned megastructures.
* KillItWithFire: Being a mobile scrap recycling plant complete with an onboard furnace, some of its attacks involve dispensing fiery death in your direction.
* RecurringBoss: [[spoiler:A second Smart Cleaner appears on the Xylem during the Liberator of Rubicon story branch.]]
* ThisIsADrill: Somewhere between this and ChainsawGood, its main weapons are the two gigantic red-hot scrap crushers on its arms.

[[folder:[=IA-13=] Sea Spider]]

[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/ac6_seaspider.jpg]]
[[caption-width-right:1000:[[MemeticMutation "Guess you just can't beat the Institute..."]]]]

A relic from before the Fire of Ibis, the Sea Spider is a "C-Weapon" that was developed by the Rubicon Research Institute. It suddenly appears to attack C4-621 while they try to board a cargo launcher to reach the Ice Fields across the ocean.

* AchillesHeel: The sheer size of it - especially in a fairly small arena - means it's ridiculously easy to hit with heavy weapons and stagger it time after time as long as you keep your camera in its general direction. In its second phase it can rain death from above on you, but barely can do anything that's actually on its elevation or above it, meaning that tetrapod legs can simply hover around it and avoid most of its most devastating attacks.
* DeathFromAbove: In its second phase it switches to a completely airborne mode, raining laser strikes on the player below. Standing on the ground during that phase can be a death sentence as the explosions happening below can wipe a large chunk of your AP.
* {{Foreshadowing}}: An Institute's weapon that suddenly appears to attack 621 once they managed to evade the firing range of the PCA Outer Shell Security laser satellites, with Carla wondering what is one doing here. It's the first hint that the PCA have direct control of several C-Weapons that they will use to eliminate problematic individuals, like the Ice Worm later on that is also sicced on 621.
* LogicalWeakness: Phase two has immense air to ground capabilities, but barely any air to air combat. If running a tetrapod Armored Core or other aerial builds, players might as well have won unless the first phase really put them through the wringer.
* LostSuperWeapon: It's a C-Weapon created by the defunct Institute, and it runs on Coral, giving it dangerous energy projectiles.
* SpiderTank: An unmanned version. Its second phase has it adopt a completely airborne form.
* SpinAttack: In its second form, one of its attacks is to project blades from its leg jets and then spin like a top around the arena.
* RecurringBoss: [[spoiler:During the final boss fight of the GoldenEnding, ALLMIND summons two second phase Sea Spiders to assist it.]]

[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/ac6_cataphract.jpg]]
[[caption-width-right:1000:When a weapons loadout pack goes too far]]

A piloted PCA Special Operations weapon designed for land warfare. The RLF requests its destruction to prevent it from falling into Corporate hands.

* AttackItsWeakPoint: Its thick armor makes it impervious everywhere, except the MT that controls the whole thing. But considering it can only be hit from the front, the PCA likely considered that an acceptable risk, reasoning that no enemy would be [[CrazyEnoughToWork crazy enough to attack the CATAPHRACT head-on.]]
* DidntSeeThatComing: The PCA Captain [[OhCrap realizes too late]] that 621 ''isn't'' the same Raven, meaning they can't be predicted.
-->'''PCA Captain:''' Code 44. Send me what you got on priority target Raven. The combat simulator has misled me. ''Who are you?'' ... Code 18. Whoever this is, it's ''not'' Raven.
* DidntThinkThisThrough: The developers of CATAPHRACT probably thought no one would be insane enough to attack it head-on because that would leave them exposed to the enormous amount of front-facing weaponry it possesses. Unfortunately, 621 is, and destroys it handily, showing they didn't think about what would happen if somebody could weave through all that firepower.
* EarlyBirdCameo: Appeared as a prominent foe in both the Reveal and Story Trailers, though with more emphasis in the latter.
* FaceDeathWithDignity: Upon defeat, the Captain's last action is to try and send his Combat Log back to the PCA to ensure his death isn't in vain.
* GameplayAndStoryIntegration: The Story Trailer shows the CATAPHRACT being completely stopped in its place by 617 ramming into it and then going full GatlingGood until their AC near-entirely failed. While you can't hold it still, it can be staggered ''really easily'' with the right weapons; even beyond the gatling gun, high ACS damage weapons like shotguns and melee in particular utterly decimate its Attitude Stability and leave it vulnerable in no time.
* GatlingGood: The CATAPHRACT has four rotary guns on its chassis -- two forward-facing and mounted on the protruding treads, and two attached to its turret.
* JumpJetPacK: Is also equipped with jump jets, mostly for short hops or to reorient itself.
* LightningBruiser: Despite its hulking size, it zips around the ice fields like a hot rod doing wheelies.
* MeaningfulName: A cataphract was form of heavy cavalry that existed in ancient Persia, Eurasia, and Northern Africa, making it an appropriate description for the PCA's latest tank.
* MetaMecha: The tank unit is actually built around basic bipedal MT, though the briefing indicates that the two are connected by the latter's shoulder sockets, meaning it can't be casually removed.
* MultiTrackDrifting: Is fast enough to do donuts across the battlefield, which is probably helped by it being battled on snow and ice.
* NoodleIncident: The pilot, confusing 621 for the original Raven, claims that the latter is to blame for the PCA losing its grip on Rubicon-3 due to some sort of leak, which allowed the Corporations to invade the planet.
* TankGoodness: It's a gigantic tank with insane speed, agility, and a ridiculous collection of weaponry.
* TurnsRed: Once damaged enough, it changes up its movement and attack patterns to keep 621 from getting a clean shot at its front.
* ViolationOfCommonSense: The primary design flaw of [[DidntThinkThisThrough shooting it head-on]] into the blaze of bullets, missiles and lasers is something no average, life-preserving combatant would ever consider trying to do unless they know damn well what they're doing, or they've got no other choice, like 617's near-sacrifice in the Story Trailer to disable a CATAPHRACT. For 621, it's the job or nothing and they have no compunctions about rushing straight into danger, so violating common sense is effectively your primary option to do anything worth a damn to the machine.
* WalkingArmory: It has four rotary guns, a missile launcher, and an energy cannon with close and long-range settings, and can also just run over anything in its way.
* WolfpackBoss: [[spoiler:The first time 621 encounters a CATAPHRACT, it will engage 621 alone in a one-on-one boss battle. However, if the player follows the Alea Iacta Est story missions, 621 will encounter a CATAPHRACT backed up a by two of the PCA's special forces mechs, the EKDROMOI. Fortunately, 621 will get some help of their own from a friendly AC pilot to turn a three-on-one dog pile into a much more manageable three-on-two.]]

[[folder:[=IA-02=] Ice Worm]]
Another Coral-powered C-Weapon left behind by the Institute, the Ice Worm is a gigantic tunneling machine that suddenly appears after 621 and Rusty just took down the PCA's berthed warship fleet. It serves as the Final Boss of Chapter 3.

[[folder:[=AAP03=] Enforcer]]

[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/ac6_enforcer.jpg]]
[[caption-width-right:1000: Termination Mode activated]]

An autonomous, AI-controlled AC tasked with guarding the underground facilities of Depth 3.

* {{BFG}}: Its main gun, a pulse cannon, is so huge it's the only AC gun in the game that is actually used with two hands like a rifle.
* FightsLikeANormal: One of the most disconcerting things about it is that it moves and fights almost exactly like an ordinary AC despite being so much larger. Most giant enemies aren't nearly so agile and versatile.
* DeadlyLunge: One of its attacks when it TurnsRed is to launch itself at you, laser blade first. If it hits, you're going to receive a nasty one-two strike from that blade.
* HumongousMecha: In a game full of ten-metre-tall humanoid combat robots, the Enforcer stands out by being at least twice the size of anything the player can field.
* JackOfAllStats: As far as ''Armored Core'' bosses go, the Enforcer is pretty run-of-the-mill. It has access to a decent selection of ranged and melee attacks, but has no special gimmicks to look out for. On the flipside, it leaves few glaring flaws in its design that can be easily exploited by the player.
* LightningBruiser: Not only does it hit like a freight train, it's almost as agile as an enemy AC (though nowhere near as fast as the Balteus).
* ShockwaveStomp: Once it TurnsRed, one of its new attacks is to leap into the air and do a SwordPlant with its laser blade that sends a shockwave of energy bursting out from around it. [[spoiler:You can avoid it by taking to the air, or navigating around to the Enforcer's rear.]]
* TransformingMecha: When you first encounter it blowing away Balam's soldiers, the Enforcer's in a configuration that makes it resemble a SpiderTank. When you finally corner it at the end of the stage, it transforms into "Termination Mode" to do battle with you.

[[folder:[=IB-07=] SOL 644 ('''MAJOR SPOILERS''')]]

[[folder:[=IB-C03=] HAL 826 ('''MAJOR SPOILERS''')]]

[[folder:'''The Final Boss''' ('''MAJOR SPOILERS''')]]

The FinalBoss of the [[spoiler:Alea Iacta Est]] path. It is [[spoiler:the SOL 644 after ALLMIND salvages and recycles it into its personal machine. It shows up to fight you after you defeat the MIND GAMMA in the first phase, bringing a whole new arsenal of weapons to bear.]]

* AceCustom: [[spoiler:It's all but outright stated that the mech ALLMIND uses in the second phase is heavily a modfied SOL 644. It sacrifices a lot of its abilities in that route in favor of souped-up blast attacks, massive WolverineClaws, two Sea Spiders backing it up, and the ability to fire massive lasers.]]
* CurbStompBattle: [[spoiler: If the sheer speed of their shock at its arrival and how fast ALLMIND responds that both have been dealt with mere seconds after C4-621 regains control of the ship they commandeered is any indication, then the MIND DELTA has effectively inflicted this on both "Cinder" Carla and Walter's HAL 826, which is noteworthy as the HAL 826 is the Final Boss in the "Liberator of Rubicon" ending and is no slouch in a fight himself.]]
* DarkIsEvil: [[spoiler:Instead of the gleaming white of the original SOL 644 and even the slightly darker silver of its predecessors, MIND DELTA is a very dark grey that almost borders on black in some shots. [[WellIntentionedExtremist Well-intentionedness]] of ALLMIND aside, Iguazu ''definitely'' qualifies, especially when he pulls a VillainOverride on ALLMIND in a later stage of their boss fight.]]
* TheDeterminator: [[spoiler:While being controlled by by Iguazu, it tries one last time to attack 621 with its WolverineClaws even as it's completely defeated and critically damaged, but only succeeds in overloading itself entirely.]]
* ExtraEyes: Initially appearing to be faceless when first encountered, it opens up its face to reveal seven bluish green eyes spaced evenly around the center, similar to its original counterpart.
* LightningBruiser: Exactly as hulking and powerful as [[spoiler:the original SOL 644]] and exactly as agile, too. [[spoiler:At least it doesn't have the Pulse Armor this time around.]]
* SwordBeam: It retains the Coral Oscillator from [[spoiler:its original self]], now colored blue this time around, but ditches it in the later stage of its fight, in exchange for its WolverineClaws.
* TurnsRed: [[spoiler:After getting knocked down to half health, MIND DELTA unleashes a massive energy wave that disables both Ayre's ECHO and ALLMIND's control over it in addition to the Sea Spiders it summoned for the fight, and then goes ''absolutely bonkers'' on you, trying to charge at you and tear you to shreds with its massive WolverineClaws, as an indication of Iguazu's current mental state.]]
* WolfpackBoss: [[spoiler:It is assisted by two second-phase Sea Spiders at the beginning of the fight, though thankfully you have your own ally in Ayre and they get disabled when Iguazu forces ALLMIND out of MIND DELTA.]]
* WolverineClaws: Its most defining feature is the three massive energy blades it unfolds from each hand in the later stage of its fight, which it slashes rapidly at you in a manner very reminiscent of the claws of an animal.

!![=51-004 K=] MIND DELTA[[note]]unofficial and may be subject to change[[/note]]

* AceCustom: It's heavily implied that [[spoiler:through virtue of its extremely similar appearance and style of movement, MIND DELTA is actually the SOL 644, the FinalBoss of the “Fires of Raven” route, after heavy modification and refurbishment to suit ALLMIND's tastes. As a result, it sacrifices a lot of its abilities in that route, such as its missiles, pulse armor, DoppelgangerAttack, and the ability to transform into a birdlike configuration and fly around the arena, but gains a lot of new ones here, such as souped up blast attacks, massive WolverineClaws, two Sea Spiders backing it up, and the ability to fire massive lasers.]]

* DarkIsEvil: [[spoiler:Instead of the gleaming white of the original SOL 644 and even the slightly darker silver of its predecessors, MIND DELTA is a very dark grey that almost borders on black in some shots. And while “evil” is a ''huge'' stretch and [[WellIntentionedExtremist may not even be applicable to ALLMIND]], the bloodlusted and enraged GreenEyedMonster Iguazu ''definitely'' qualifies, especially when he pulls a VillainOverride on ALLMIND in the later stage of their boss fight.]]

* CurbStompBattle: [[spoiler: If the sheer speed of their shock at its arrival and how fast ALLMIND responds that both have been dealt with mere seconds after C4-621 regains control of the ship they commandeered is any indication, then the MIND DELTA has effectively inflicted this on both "Cinder" Carla and Walter's HAL 826, which is noteworthy as the HAL 826 is the Final Boss in the "Liberator of Rubicon" ending and is no slouch in a fight himself.
