* AchillesHeel:
** One of the first of many examples of a bulky unit with huge DEF and no RES, making them borderline impervious to physical damage (especially considering the units you should have when they first appear), but very weak to Arts. These guys should be your first lesson in using Arts to take out armored units.
** Painfully averted with the Guerilla Shieldguards, which have high DEF ''and more RES than most Caster enemies'' to make sure that killing them is a slow and arduous process. The Dublinn versions have even higher RES than the Shieldguards, but also have less HP and DEF.
* AntiMagic: The Dublinn variants wear Arts-refracting masks that greatly increase their RES, eliminating their AchillesHeel. The masks can be temporarily disabled by Silencing them.

* EliteMook: They're considered Elite enemies in all of their variations.

* HeavilyArmoredMook: The riot armor they wear offers incredible defense against physical attack, but not against Arts (unless they're a Guerilla Shielder).
* HelpfulMook: On M8-6, 4 (allied) Guerilla Shielders are the only things standing between a massive horde of Enraged Posessed and a blue base. You need to go help them because they will get overwhelmed, and passing the level without letting any of them die is required to unlock a secret story node.

* MightyGlacier:
* ShieldBash: The only weapon they have is their shields, so bashing operators is their only mean of attacking. It still does more damage than a sword slash from a basic soldier.

* KillItWithIce: The Oneiros variant drops a special bomb that detonates in a freezing Arts blast on impact. While it deals a lot less damage than the normal Bombtails, it also applies a cold effect in a wide area, which can outright freeze operators solid if they are hit with another cold attack in the next few seconds.

* AchillesHeel: Despite their disturbingly high health, attack power, and defense, they have ''0'' RES, making them highly vulnerable to Arts damage.

!Sargon Units
!!!Tiacauh Tribe (Introduced in ''Gavial the Great Chief Returns'')
[[folder:General]]
* LizardFolk: They are Acahuallan tribesmen that bear an appearance to alligators.

[[folder:Tiacauh Warrior]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/avg_npc_070.png]]
->'''Other variations:''' Tiacauh Guard
Archosaurus melee fighters who will gain additional DEF while being blocked.

* StatusBuff: Whenever an Operator blocks them they receive a significant DEF boost, this makes them dangerous to non-Defender Operators that attempt to engage them in a fight.
* WeaponsOfTheirTrade: Befitting their nature as tribesmen, they fight with a crudely built spear.

[[folder:Tiacauh Lancer]]
->'''Other variations:''' Tiacauh Sniper
Archosaurus warriors who throw ranged spear attacks.

* ThrowingYourSwordAlwaysWorks: They throw their spears as their ranged attack.

[[folder:Tiacauh Fanatic]]
->'''Other variations:''' Tiacauh Ripper
Archosaurus warriors who wield acid-coated gauntlets, giving them both fast attack speed and the ability to apply a permanent stacking DEF debuff on targets.

* AntiArmor: Their attacks apply stacked DEF debuffs to their target, much like Acid Originium Slugs.

[[folder:Tiacauh Ritualist]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/avg_npc_071.png]]
->'''Other variations:''' Tiacauh Shaman
Archosaurus casters that use Arts attacks. If they are blocked, they will gain increased DEF and start using melee attacks that deal significantly higher physical damage.

* MagicStaff: Not only can they fire ranged Arts attacks with it, but if they get blocked, they will resort to melee attacks with their staff, dealing ''quadruple physical'' damage to your operators.

[[folder:Tiacauh Shredder]]
->'''Other variations:''' Tiacauh Annihilator
Elite Archosaurus warriors armed with military equipment that gives them higher stats. They can also periodically destroy nearby mushroom or stump tiles, disabling their effects and making it impossible to deploy units there.

* ChainsawGood: Fights with dual buzzsaws.

[[folder:Tiacauh Brave]]
->'''Other variations:''' Tiacauh Champion
The strongest of the Tiacauh warriors who only partake in one-on-one duels. If blocked, they will reduce both their own DEF and that of their target by 70%, draw aggro from the blocker, and become immune to all damage outside of that from their opponent.
----
* DrawAggro: From whoever's blocking them.
* DuelBoss: Once they are blocked, they will only take damage from the blocking Operator, making it a 1v1 battle.
* DuelToTheDeath: What happens when you try to block one. The Brave/Champion will force the blocking operator into an 1v1, with both forced to attack each other.

!!!Drudge's Mercenaries & Originiutants (Introduced in ''Originium Dust'')

[[folder:Originiutant Puppet]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_originiutantpuppet.png]]

Human remains parasitized and reanimated by Originiutants. Divides into two Originiutant Excrescences on death.

* OurZombiesAreDifferent: They are the first (and only, until the introduction of Dublinn Flamecallers and Flamechaser Guards) true undead unit introduced, as the Possessed Soldiers and Junkmen are half-dead (but self-aware) people controlled through Mephisto's Arts.

[[folder:Mutant Sand Beast]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_mutantsandbeast.png]]
->'''Other variations:''' Mutant Sand Beast α

Swift, omnivorous desert beasts trained by the Sargonians as hunting partners, they have become infected with Originiutants. Divides into two Originiutant Excrescences on death, or Tumors if it's an α variant.

* BearsAreBadNews: Its model appears to be based upon a bear, and it's infected with something that seems to be on the same threat level as the [[EldritchAbomination Seaborn]] from ''Under Tides''.

[[folder:Mutant Rock Spider]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_mutantrockspider.png]]
->'''Other variations:''' Mutant Rock Spider α

Sargonian arachnids parasitized by Originiutants. Divides into three Originiutant Excrescences on death, or Tumors if it's an α variant.

* BigCreepyCrawlies: Although they're actually unrelated to the more common Infused Originium Slugs.

[[folder:Mutant Giant Rock Spider]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_mutantgiantrockspider.png]]
->'''Other variations:''' Mutant Giant Rock Spider α

A subspecies of Rock Spider native to Sargon with a bulky abdomen that stores energy, infected by Originiutants. A bulky ranged enemy that continuously spawns Originiutant Excrescences (Tumors if it's an α variant), and explodes into four of them upon death.

* BigCreepyCrawlies: Even bigger and meaner than a regular Rock Spider.
* MookMaker: Spits out an Originiutant Excrescence or Tumor every 5 seconds, which can build up quickly if multiple Giant Rock Spiders are active at once.

[[folder:Originiutant]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_originiutant.png]]
->'''Other variations:''' Originiutant α

A heavily mutated Originium behemoth used as a living weapon. Although they are very slow, their exoskeletons give them ungodly resilience and devastating melee Arts attacks.

* ArmoredButFrail: These beasts have some of the highest mixed defenses in the entire game (comparable to ''Patriot'' of all things), which makes them take very little damage from just about everything. Once you look past that, however, their actual HP is surprisingly low, with even the strongest variant of them having less health than an ordinary Heavy Defender.
* MightyGlacier: They're extremely resilient to all types of conventional damage, and deal massive amounts of Arts damage with each strike. To compensate, they attack very slowly and move even slower.

[[folder:"Redmark" Eradicator]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_redmarkeradicator.png]]
->'''Other variations:''' Elite "Redsign" Eradicator

A camouflaged mercenary sniper who uses extraordinarily lethal attacks from anywhere on the map, but can only attack Operators exposed to a sandstorm.

* AchillesHeel: Operators not caught in a sandstorm, if forced into a melee combat, they will only use a melee attack which only deal a small amount of damage.
* ColdSniper: They are capable of ''sniping'' Operators caught in the sandstorm anywhere on the map. This, coupled with their high ATK stat, makes them extremely dangerous to an affected Operator.
* EliteMook: Unusually for the infantry presented for ''Operation: Originium Dust'', these enemies are always categorized as an Elite Enemy, making them the only enemy group to lack a Common Enemy representing the "Redmarks".

[[folder:"Redmark" Infiltrator]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_redmarkinfiltrator.png]]
->'''Other variations:''' Elite "Redsign" Infiltrator, Holographic Illusion, Holographic Illusion [=MK2=]

A mercenary saboteur who spawns a hologram to distract targets upon first taking damage; while the hologram is active, they'll gain negative targeting priority and immunity to blocking, letting them sneak past. They'll also get a significant amount of evasion if they're exposed to a sandstorm.

* MesACrowd: They can project a holographic copy of them if attacked for the first time, until the copy is destroyed, they can easily pass through a defensive line.

[[folder:Originiutant Excrescence]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_originiutantexcrescence.png]]
->'''Other variations:''' Originiutant Tumor

Twisted life-forms created by Levi Klitschko's experiments with radiation and Originium, capable of parasitizing others and mutating them. They do not count towards the enemy counter and only spawn from certain other enemies, but swarm en masse and still cause life loss if they escape; the stronger Tumor variant has an additional ability to massively lower the attack speed of any Operator blocking them.

* ZergRush: Their entire modus operandi; especially the Tumors, which can all but paralyze melee Operators.

!Siesta Units
!!!Little Black Sheep (introduced in ''So Long, Adele'')

[[folder:General]]
* PiecesOfGod: These are clones of Dolly that developed their own personalities, not unlike the [[spoiler:Sui siblings]]. The finale of "So Long, Adele" reveals that [[spoiler:their personalities are copies of people that Dolly deemed "interesting" during his long life.]]
* KillerRabbit: Despite looking like cute pink-colored sheep, these guys are actually deadly and are just as capable in doing damage to your operators.
* RidiculouslyCuteCritter: They are literally ''pink sheep''.
* StickyFingers: Some of the familiars carry man-made items that they picked up off the street or looted from human shops, and Eyjafjalla spent a while in "So Long, Adele" chasing down one that stole random items from other people. Dolly even lampshades it early into the event.
-->''You're going to humiliate me. Don't tell people my clones are kleptomaniacs.''

[[folder:Hot Spring 'Mischievous Rascal']]
->'''Other variations:''' Hot Spring 'Jolly Rascal'
A sheep familiar wearing a traffic cone. Spawns a Carmine Steam on the spot when defeated.

[[folder:Fashion Street 'Hearty Heavy']]
->'''Other variations:''' Fashion Street 'Robust Heavy'
A sheep familiar carrying a frisbee. Has a ranged attack and also spawns a Carmine Steam on the spot when defeated.

[[folder:Fashion Street 'Ordinary Aviator']]
->'''Other variations:''' Fashion Street 'Hyperactive Aviator'
A sheep familiar wearing aviation gear. Has Low-Altitude Hovering and even though they have no attack by themselves, they can grab on a 'Hearty Heavy' to gain a ranged attack.

* AchillesHeel: Disabling status effects (stun, frozen, sleep) will cause the Aviator to lose its Low-Altitude Hovering, becoming a ground unit that uses a melee attack when blocked. This also disables its ability to carry Hearty Heavies.
* DisneyDeath: Their path in some operations take them over bottomless pits, which can result in the Aviator and its potential Heavy passenger falling to their doom if it receives a disabling status effect while over the pit.
* MaybeMagicMaybeMundane: They are often mistaken for pink clouds by Siestans, leading to legends of pink clouds surrounding the volcano that were often dismissed as exaggerations.

[[folder:Hot Spring 'Wandering Vagrant']]
->'''Other variations:''' Hot Spring 'Wandering Slider'
A sheep familiar wearing skating equipment. Has invisibility, and can carry a 'Mischievous Rascal' on them which also gives them the ability to spawn Carmine Steam on tiles that they pass through.

* TheSneakyGuy: They are invisible until blocked.

[[folder:'Big Fella']]
->'''Other variations:''' 'Big Man'
A large fluffy critter that sometimes unintentionally eats its own kin. Spawns a 'Mischievous Rascal' on first attack, or when defeated.

* BigEater: Is not picky with what it eats, to the point that it will sometimes eat the other familiars and then spit them back out as ammo for their attacks.

[[folder:Urban 'Whirlwind Walker']]
->'''Other variations:''' Urban 'Tornado Trendsetter'
Two familiars that got entangled with each other from fighting over cotton candy. Explodes on first attack to deal Arts damage, leaving behind a 'Mischievous Rascal' and a 'Hearty Heavy'.
----
* ActionBomb: Blows up on the first time they attack, dealing Arts damage to whoever is unlucky enough to block them. And unlike some other enemies that also explode on death (i.e. infused Originium slugs), this ''cannot'' be stopped using Silence status effect.
* FlunkyBoss: Spawns a 'Mischievous Rascal' and a 'Hearty Heavy' after death.
* StickyFingers: Both literally (cotton candy is ''sticky'') and also figuratively from their flavor text.
-->''The main reason the Candy House grandpa is so angry is because they snatched his wig off too!''

[[folder:'Fluffy Buddy']]
A sheep familiar that hides in the map. Appears as a blur of blue static until covered in Steam, at which point they explode and either heal or inflict Arts damage, plus leaving behind more Steam of the same color.
----
* HelpfulMook: If covered in Pure White Steam, they will heal your operators and leave behind more Pure White Steam. They will explode for Arts damage if covered in Carmine Steam, however.

[[folder:Fashion Street 'Stellar Caster']]
->'''Other variations:''' Fashion Street 'Supernova Caster'
A sheep familiar carrying a witch's gear from a divination shop. Attack up to three operators at a time if standing in Carmine Steam.
----

!!Ursus Units
!!!Ursus Imperial Army and civilians (Introduced in Chapter 8)
[[folder:General]]

* SecretAIMoves: The ability to use ranged attacks, they only use it on allied units (friendly [=NPCs=]) and ''never'' on active Operators.

[[folder:Ursus Civilian]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/avg_npc_081.png]]

Harmless civilians that will attempt to flee to blue boxes for safety. Players must protect them, as letting a Civilian die will be counted as a life loss.

* AssholeVictim: Hard to shed a tear for them when they get massacred in [=JT8-1=], considering what they did with the infected ones and [[ArsonMurderAndJaywalking being as unhelpful as possible in battle]].
* EscortMission: Their very presence creates one. Letting them die is equivalent to leaking an enemy, and considering that they're [[TooDumbToLive pretty suicidal]] in [[ThatOneLevel some levels]]...
* ManOnFire: In [=JT8-1=], the first victim of Talulah's rampage is [[CruelAndUnusualDeath slowly burned alive]]. The rest of the Civilians at least get a quicker death.

[[folder:Ursus Mangler]]
->'''Other variations:''' Ursus Mangler Packmother

A ruthless pack beast trained by the Ursus military.

* UndergroundMonkey: They are essentially Reunion Hounds that boast better stats, making them more threatening in numbers.

[[folder:Infected Patrol Captain]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/avg_npc_082.png]]
->'''Other variations''': Elite Infected Patrol Captain

Vanguards from the Ursus Army in charge of hunting down infected civilians.

* ZeroPercentApprovalRating: Forget their enemies, the description of the Elite Patrol Captain says that they're generally despised by the soldiers and city officials of Ursus alike, despite their shared anti-Infected stance.
* LongRangeFighter: They can target the Ursus Civilians and Talulah the Fighter using throwing knives.
* NonIndicativeName: Despite the "captain" in their name, they are the most commonly encountered enemies in Chapter 8, making them more akin to specialized regular soldiers than those holding high ranking positions within the army.
* SociopathicSoldier: Described as greedy and cold-blooded, the patrols don't give a crap about human life, as they constantly persecute and murder innocent infected villagers. [[GameplayAndStoryIntegration This is even a part of gameplay]], as all of the Ursus troops in Chapter 8 ''actively prioritize attacking civilians over Operators.''
* WouldHarmASenior: [[spoiler:They have no qualms about offing old people, as Ivan would find out later.]]

[[folder:Ursus Assault Crossbowman]]
-> '''Other variations''': Elite Ursus Assault Crossbowman

Ranged attackers for the Ursus Imperial Army, carrying a jet pack to launch surprise attacks.

* StraightForTheCommander: Another of their priorities; they will target Talulah the Fighter and will prioritize her over active Operators.
* UndergroundMonkey: They function similarly to their Reunion counterparts, but carrying a crossbow instead of a melee weapon.
* WouldNotShootACivilian: Inverted. They will prioritize shooting at Ursus Civilians over Operators.

[[folder:Ursus Armored Caster]]
-> '''Other variations''': Elite Ursus Armored Caster

Casters that serve under the Ursus Imperial Army.

* StraightForTheCommander: Another of their priorities; they will use their Arts on Talulah the Fighter and will prioritize her over active Operators.
* SquishyWizard: Subverted. They are surprisingly durable thanks to the armor they're wearing (hence the name), giving them much more protection compared to the other casters.
* WouldNotShootACivilian: Inverted. They will prioritize using ranged Arts at Ursus Civilians over Operators.

[[folder:Guerrilla Herald]]
->'''Other variations:''' Guerrilla Herald Leader

Special forces deployed by Patriot. While their combat ability is poor, they will passively provide a stacking ATK/DEF buff to all foes on the map while activating the special abilities of most Guerrilla units.

* PaletteSwap: Of the Reunion Technical Scout. They sport the same general moveset and aura-based abilities, but whereas Tech Scouts offer the enemy team TrueSight, Heralds provide a StatusBuff to every non-Herald unit on the map instead.
* SupportPartyMember: While they can't fight very well, their global buffing abilities make them a priority target to take out whenever they appear.
* StatusBuff: Grants all enemies +10% ATK and +100 DEF as long as they're alive, which stacks additively if more than one is alive. They'll also activate the special abilities of most Guerrilla troops.

[[folder:Ursus Raider]]
->'''Other variations:''' Ursus Raider Leader

Imperial soldiers trained to break enemy lines. They prioritize attacking civilians and can only be blocked by Operators with 2 block or higher.

* EliteMook: Being stronger than the Captains, they count as two enemies when blocking--this makes them a threat to those with only one block as they simply pass through them.
* LongRangeFighter: Like Captains, they will pull out a knife and use it on Ursus Civilians and Talulah the Fighter.

[[folder:Imperial Striker]]
->'''Other variations:''' Elite Imperial Striker

The heavy soldiers of the Ursus Imperial Army who can launch with harpoons at range and use a spiked tip at melee range. Their attack power will double once they drop below half health.

* GiantMook: Of the Ursus Imperial Army, their imposing height and muscular build makes them suitable for taking on stronger Operators.
* HarpoonGun: They carry a wrist-mounted harpoon launcher as their primary weapon. They only use it on allied units such as Talulah the Fighter and Ursus Civilians, otherwise they will simply stab blocking Operators with it.
* MightyGlacier: Their movement speed isn't that fast, but they make up with high mixed bulk and strong attacks.
* TurnsRed: Their attack doubles when below 50% HP. Considering that they hit hard to begin with, this is usually bad news if you can't kill them quickly after this point.

[[folder:Imperial Artillery Targeteer]]
->'''Other variations:''' Imperial Artillery Core Targeteer

Heavily armored drones who don't attack manually but mark targets for Ursus artillery bombardment, calling in explosive airstrikes that deal severe area damage to their targets.

* DeathFromAbove: Calls in artillery strikes from above to do massive splash damage.
* MightyGlacier: They deal massive damage, have sturdy defenses, and pack massive amounts of HP, but they're extremely slow to compensate.

!Great Yan Units
!!!Ink Spirits (Introduced in ''Who is Real'')

[[folder:"Angry"]]
->'''Other variations:''' Anxious "Angry"

A fast-moving, ill-tempered Ink Spirit. Like all of their Ink Spirit brethren, they can exploit the Hui/Ming mechanic found in their event, dealing and taking bonus damage from Operators with the opposite attribute, and decreased damage from those with the same attribute.

[[folder:"Bitey"]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/avg_avg_npc_143_1.png]]
->'''Other variations:''' Serious "Bitey"

A basic Ink Spirit with a curious, sociable personality.

[[folder:"Stabby"]]
->'''Other variations:''' Flanking "Stabby"

A prideful Ink Spirit whose ranged attacks prioritize attacking Operators with the opposite attribute as itself.

[[folder:"Lazy"]]
->'''Other variations:''' Unmoving "Lazy"

A massive, sedentary Ink Spirit with equally massive bulk and the ability to draw Operator fire to itself.

[[folder:"Smarty"]]
->'''Other variations:''' Dazzled "Smarty"

A lively Ink Spirit with low stats, but the ability to explode into a powerful Arts explosion on death. If two Smarties with opposing attributes come into close proximity, they'll instantly detonate in an unfathomably powerful blast.

* ActionBomb: It will explode upon getting killed, dealing quadruple their ATK Arts damage in the surrounding tiles. If two opposing Smarties meet, the resulting explosion will deal anywhere between ''1350% to 1650%'' of their ATK as Arts damage, which will almost certainly one-shot whatever is in range.
* HoistByTheirOwnPetard: They can get themselves killed by their own carelessness if two "Smarties" with different Hui/Ming attributes get close to each other. Sadly, it ''[[OneHitKill won't be pretty]]'' if your operators get caught in the ensuing blast.

[[folder:"Blindey"]]
->'''Other variations:''' Indefatigable "Blindey"

A reckless Ink Spirit with above-average stats and the ability to pass through any Operator without the same attribute as itself.

[[folder:"Envy"]]
->'''Other variations:''' Complicated "Envy"

A frightening, neurotic Ink Spirit with powerful Arts attacks. They'll periodically charge up special attacks that deal heavy Arts damage and forcibly change the attribute of their target.

[[folder:"Fury"]]
->'''Other variations:''' Unbridled "Fury"

A hulking but dimwitted brute of an Ink Spirit that deals massive damage against Operators with the opposite attribute as itself.

* DumbMuscle: Extremely powerful, but too stupid to make good decisions in combat.

[[folder:"Free"]]

The main boss of "Who is Real". It is the strongest familiar of Dusk, an enormous unforgiving Ink Spirit with a cold, arrogant, and domineering presence.

* BarrierChangeBoss: Switches its attribute from Ming (white) to Hui (black) when it TurnsRed, changing its strength and weakness to match.
* DeflectorShields: Its Break the Chains attack has him stop and protect himself with a barrier that absorbs a certain amount of damage. If you don't destroy the shield fast enough, it'll [[ActionBomb explode]] with enough damage to OneHitKill virtually anything caught in the blast. Not breaking the shield at all during its second battle is actually required for one of the event medals.
* LargeAndInCharge: The biggest of the Ink Spirits, and by far the most powerful.
* LaterInstallmentWeirdness: Free is the only "Public Affairs" event boss who is not represented with a cutscene sprite, nor with a CG image. Just like the Sarkaz Centurion, it's treated as just another foe more than a proper character, although it's far stronger.
* TurnsRed: When it's first defeated, it'll fully restore his HP and empower all of its attacks, in addition to using its Weft and Warp ability and basic attack on two targets simultaneously.

!!!Waregeists (Introduced in ''Invitation to Wine'')

[[folder:General Waregeist tropes]]
* AnimateInanimateObject: Waregeists are essentially collections of mundane objects (such as paperweights, picture frames, vases etc.) whose spirits have been awakened and driven to aggression [[spoiler:by the spirit fragment of the Second Brother contained within the black goblet]].
* AsteroidsMonster: When defeated, each Waregeist spawns a number of Enchanted Objects that don't attack, can't be blocked, and require a certain number of hits to defeat, regardless of how powerful those individual hits are. This encourages strategies based around operators with high attack speed, attacks that hit multiple times at once, and damage-over-time effects[[note]]since each time the effect triggers is considered a separate "hit"[[/note]].
* ItsProbablyNothing: In the early story segments of "Invitation to Wine," a number of characters spot Waregeists sneaking around before they begin to appear in significant numbers, but each time they dismiss it as a trick of the light, a fatigue-induced hallucination, or some manner of mundane animal. It's only when the things start to swarm that people really notice what they actually are.
* ZergRush: In-story, individual Waregeists aren't particularly powerful, but they appear in great numbers and don't stop coming. In-game, their nature as {{Asteroids Monster}}s means that if you're not careful, your defensive lines will get overrun by massive numbers of unblockable enemies that you can't kill fast enough to win.

[[folder:Grindstone]]
->'''Other variations:''' Brightmirror

A canine-like Waregeist made from wooden seals. Spawns 2 wooden seals when defeated.

[[folder:Vernacularism]]
->'''Other variations:''' Sophistication

A soldier Waregeist made from novel scrolls. Spawns 3 novel scrolls when defeated.

[[folder:Introspection]]
->'''Other variations:''' Scantwords

A Waregeist created from a mirror that resembles a bird. Taunts operators into attacking it, and spawns a mirror when defeated.

* IShallTauntYou: It taunts operators into attacking it over other enemies by "revealing their inner secrets in their truest form".

[[folder:Inkwave]]
->'''Other variations:''' Heartbillow

A stone lion-shaped Waregeist created from a fusion of multiple paperweights. Spawns 15 wooden paperweights when defeated.

* MightyGlacier: Not particularly fast moving, but they have good HP and DEF as well as high attack damage.
* ZergRush: Is the epitome of this among Waregeists as they spawn '''15''' paperweights on defeat that requires 2 hits each to kill, making [=AoE=] attacks more or less required to fully clean them up.

[[folder:Fountainboil]]
->'''Other variations:''' Rainbowbrew

A Waregeist made from a tea set resembling a hermit crab with a teapot as its shell. Deals splash Arts damage on attack and explodes upon death to debuff nearby operators with slowed attack speed. Spawns 4 celadon teawares when defeated.
----
* AchillesHeel: Similar to Infused Originium Slugs, Silence status effect prevents it from exploding on death.

[[folder:Blueflower]]
->'''Other variations:''' Scarletmist

A Waregeist created from a vase that appears as a dragon riding on the vase. Can inflict a debuff that causes operators to take increased Arts damage over time. Spawns a celadon vase when defeated.

* AchillesHeel: Silence status effects prevents the Blueflower from using its debuffing attack as well as freezing the attack count, removing its main source of danger.
* DamageOverTime: After a few attacks, the Blueflower can launch a stronger attack (shown by the attack coming out of the vase instead of the dragon) that inflicts increasing Arts damage over time on the victim.

[[folder:Sinkingsand]]
->'''Other variations:''' Sharpedge

A Waregeist resembling a warrior made from bronze spearheads. Has four "Broken Blades" on spawn, which buffs its attack by 70% and consumes one "Broken Blade" per attack. Spawns spearheads based on the amount of remaining Broken Blades it has at the time of defeat.

[[folder:Clarity]]
->'''Other variations:''' Magnificence

A Waregeist made from a lampstand that resembles a bird statue. Periodically grants nearby enemies invisibility. Spawns a bronze lampstand on defeat.

* TheSneakyGuy: Not itself, but Clarity can produce a smokescreen that grants invisibility to nearby Waregeists.

[[folder:Wisp]]

Fragments of Sui's main body. Increases Sui-Xiang's max HP and reduces the charging time of its special ability when absorbed.

[[folder:Shanhaizhong Relayer]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/arknights_shanhaizhongrelayertalksprite.png]]
->'''Other variations:''' Shanhaizhong Harbringer

Tacticians specialized in relaying orders via ciphers. Deploy a Shanhaizhong Cipher on the first unoccupied Yumen Catastrophe Defense tile that they pass through.

* DroneDeployer: They put down stationary ciphers that give a movement speed and ASPD buff to all enemy units on the field, making it imperative to either stop them from reaching Yumen Catastrophe Defense tiles or destroy the deployed ciphers.
* MalevolentMaskedMen: Wear golden full-face masks that resemble animal skulls.

* ElementalRockPaperScissors: The Yeti variants deal 50% bonus damage to frozen targets.

* JetPack: Airborne Soldiers and Guerilla Assault Fighters have the ability [[ItsRainingMen to suddenly land anywhere on the field]], and can be a pain when they land directly on top of operators, such as in ''CE-4: Prisoner Transfer Escort'' where they can land on top of Medics and Casters before moving on to wreck havoc on your frontline in conjunction with the Heavy Defender Leaders in that same mission. The good thing is that because the JetPack they use is disposable, they cannot just jump around the map.
* LuckilyMyShieldWillProtectMe: Shielded variants of basic Reunion soldiers appear in later maps. They possess higher health and defenses, but are just as vulnerable to Arts as their unshielded counterparts.

* UndergroundMonkey: Later stages introduce variants of both shielded and unshielded Reunion soldiers, usually belonging to a another faction/group, with different name, appearance and stats. Their behavior is largely the same.

* NonActionGuy: Averted. They are completely unarmed like Wraiths, and also specialize in electronics like them. But they are capable of defending themselves by kicking at any foes that block them.

->'''Other variations:''' Hateful Avenger

* BookEnds: The original Contingency Contract Beta in the Area 59 Ruins had Hateful Avengers as arguably the most dangerous threats, giving them their now-legendary reputation. Come the twelth and final season of Contingency Contract, Operation Basepoint, the permanent map not only serves as a homage to CC Beta's, but features both regular Hateful Avengers and a special boss variant [[RememberTheNewGuy who is explicitly one of the survivors of the first battle in the Area 59 Ruins]] after training and returning for revenge.

[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_yetiicecleaver.png]]
->'''Other variations:''' Yeti Icecleaver Leader

Yeti Squadron soldiers who wield long katanas. They have high stats and can deal massive damage to frozen operators.

* ElementalRockPaperScissors: They deal a whopping 250% bonus damage to frozen targets - 300% if it's a leader. Combined with their naturally high ATK, they can usually kill frozen units in 1-2 hits.
* KatanasAreJustBetter: Like the Avengers before them, they wield katanas and are skilled with using them.
* MightyGlacier: They have very high HP, surprisingly good mixed defenses, and can hit for severe damage, but aren't very fast.

[[folder:Demolitionist]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_demolitionist.png]]
->'''Other variations:''' Demolitionist Leader

Reunion elites clad in heavy blast suits and wielding huge Originium sledgehammers. They use explosive strikes that deal severe damage in an area around their target.

* AchillesHeel: Just like their Defense Crusher cousins, they have no Arts resistance whatsoever.
* EarlyBirdCameo: Due to ''Children of Ursus'' being pushed up ahead of ''Darknights' Memoir''[[note]]Their debut event in CN servers[[/note]] on Global servers, these guys ended up appearing much earlier than they're supposed to.
* MightyGlacier: Demolitionists have slightly less DEF than the Crushers, but compensate with higher HP and ''much'' stronger ATK, which is further boosted by their splash damage capabilities. However, like the Crushers they're also very slow to move and attack, although they're fittingly capable of ''far'' higher damage output.
* SplashDamageAbuse: Their attacks deal damage to their primary target and any targets on the four cardinal tiles beside them. Considering that even the regular Demolitionists have a whopping 1700 ATK (almost double that of a normal Defense Crusher), a hit from a Demolitionist is going to ''hurt'' for everyone in the area, although the splash damage to the secondary targets is only 50% of their ATK. Most importantly, however, their splash damage can hit operators up on the high ground, so plan carefully where you're placing your Medics and other ranged units.

* DuelBoss: Once they are blocked, they will only take damage from the blocking Operator, making it a 1v1 battle.
* DuelToTheDeath: What happens when you try to block one. The Brave/Champion will force the blocking operator into an 1v1, with both forced to attack each other.

Human remains parasitized and reanimated by Originiutants. Divides into two Originiutant Excrescences on death.

* OurZombiesAreDifferent: They are the first (and only, until the introduction of Dublinn Flamecallers and Flamechaser Guards) true undead unit introduced, as the Possessed Soldiers and Junkmen are half-dead (but self-aware) people controlled through Mephisto's Arts.

* BigCreepyCrawlies: Even bigger and meaner than a regular Rock Spider.
* MookMaker: Spits out an Originiutant Excrescence or Tumor every 5 seconds, which can build up quickly if multiple Giant Rock Spiders are active at once.

[[folder:Originiutant]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/arknights_originiutant.png]]
->'''Other variations:''' Originiutant α

A heavily mutated Originium behemoth used as a living weapon. Although they are very slow, their exoskeletons give them ungodly resilience and devastating melee Arts attacks.

* ArmoredButFrail: These beasts have some of the highest mixed defenses in the entire game (comparable to ''Patriot'' of all things), which makes them take very little damage from just about everything. Once you look past that, however, their actual HP is surprisingly low, with even the strongest variant of them having less health than an ordinary Heavy Defender.
* MightyGlacier: They're extremely resilient to all types of conventional damage, and deal massive amounts of Arts damage with each strike. To compensate, they attack very slowly and move even slower.

A camouflaged mercenary sniper who uses extraordinarily lethal attacks from anywhere on the map, but can only attack Operators exposed to a sandstorm.

* AchillesHeel: Operators not caught in a sandstorm, if forced into a melee combat, they will only use a melee attack which only deal a small amount of damage.
* ColdSniper: They are capable of ''sniping'' Operators caught in the sandstorm anywhere on the map. This, coupled with their high ATK stat, makes them extremely dangerous to an affected Operator.
* EliteMook: Unusually for the infantry presented for ''Operation: Originium Dust'', these enemies are always categorized as an Elite Enemy, making them the only enemy group to lack a Common Enemy representing the "Redmarks".

[[folder:"Redmark" Infiltrator]]

->'''Other variations:''' Elite "Redsign" Infiltrator, Holographic Illusion, Holographic Illusion [=MK2=]

A mercenary saboteur who spawns a hologram to distract targets upon first taking damage; while the hologram is active, they'll gain negative targeting priority and immunity to blocking, letting them sneak past. They'll also get a significant amount of evasion if they're exposed to a sandstorm.

* MesACrowd: They can project a holographic copy of them if attacked for the first time, until the copy is destroyed, they can easily pass through a defensive line.

[[folder:Originiutant Excrescence]]

->'''Other variations:''' Originiutant Tumor

Twisted life-forms created by Levi Klitschko's experiments with radiation and Originium, capable of parasitizing others and mutating them.

* RidiculouslyCuteCritter: They are literally ''pink sheep''.
* StickyFingers: Some of the familiars carry man-made items that they picked up off the street or looted from human shops, and Eyjafjalla spent a while in "So Long, Adele" chasing down one that stole random items from other people. Dolly even lampshades it early into the event.

->'''Other variations:''' Fashion Street 'Hyperactive Aviator'
A sheep familiar wearing aviation gear. Has Low-Altitude Hovering and even though they have no attack by themselves, they can grab on a 'Hearty Heavy' to gain a ranged attack.
----
* AchillesHeel: Disabling status effects (stun, frozen, sleep) will cause the Aviator to lose its Low-Altitude Hovering, becoming a ground unit that uses a melee attack when blocked. This also disables its ability to carry Hearty Heavies.
* DisneyDeath: Their path in some operations take them over bottomless pits, which can result in the Aviator and its potential Heavy passenger falling to their doom if it receives a disabling status effect while over the pit.
* MaybeMagicMaybeMundane: They are often mistaken for pink clouds by Siestans, leading to legends of pink clouds surrounding the volcano that were often dismissed as exaggerations.

* FlunkyBoss: Spawns a 'Mischievous Rascal' and a 'Hearty Heavy' after death.
* StickyFingers: Both literally (cotton candy is ''sticky'') and also figuratively from their flavor text.

A massive, sedentary Ink Spirit with equally massive bulk and the ability to draw Operator fire to itself.

[[folder:"Smarty"]]
->'''Other variations:''' Dazzled "Smarty"

A lively Ink Spirit with low stats, but the ability to explode into a powerful Arts explosion on death. If two Smarties with opposing attributes come into close proximity, they'll instantly detonate in an unfathomably powerful blast.

* ActionBomb: It will explode upon getting killed, dealing quadruple their ATK Arts damage in the surrounding tiles. If two opposing Smarties meet, the resulting explosion will deal anywhere between ''1350% to 1650%'' of their ATK as Arts damage, which will almost certainly one-shot whatever is in range.
* HoistByTheirOwnPetard: They can get themselves killed by their own carelessness if two "Smarties" with different Hui/Ming attributes get close to each other. Sadly, it ''[[OneHitKill won't be pretty]]'' if your operators get caught in the ensuing blast.

* BarrierChangeBoss: Switches its attribute from Ming (white) to Hui (black) when it TurnsRed, changing its strength and weakness to match.
* DeflectorShields: Its Break the Chains attack has him stop and protect himself with a barrier that absorbs a certain amount of damage. If you don't destroy the shield fast enough, it'll [[ActionBomb explode]] with enough damage to OneHitKill virtually anything caught in the blast. Not breaking the shield at all during its second battle is actually required for one of the event medals.
* LargeAndInCharge: The biggest of the Ink Spirits, and by far the most powerful.
* LaterInstallmentWeirdness: Free is the only "Public Affairs" event boss who is not represented with a cutscene sprite, nor with a CG image. Just like the Sarkaz Centurion, it's treated as just another foe more than a proper character, although it's far stronger.
* TurnsRed: When it's first defeated, it'll fully restore his HP and empower all of its attacks, in addition to using its Weft and Warp ability and basic attack on two targets simultaneously.

!!!Waregeists (Introduced in ''Invitation to Wine'')

[[folder:General Waregeist tropes]]
* AnimateInanimateObject: Waregeists are essentially collections of mundane objects (such as paperweights, picture frames, vases etc.) whose spirits have been awakened and driven to aggression [[spoiler:by the spirit fragment of the Second Brother contained within the black goblet]].
* AsteroidsMonster: When defeated, each Waregeist spawns a number of Enchanted Objects that don't attack, can't be blocked, and require a certain number of hits to defeat, regardless of how powerful those individual hits are. This encourages strategies based around operators with high attack speed, attacks that hit multiple times at once, and damage-over-time effects[[note]]since each time the effect triggers is considered a separate "hit"[[/note]].
* ItsProbablyNothing: In the early story segments of "Invitation to Wine," a number of characters spot Waregeists sneaking around before they begin to appear in significant numbers, but each time they dismiss it as a trick of the light, a fatigue-induced hallucination, or some manner of mundane animal. It's only when the things start to swarm that people really notice what they actually are.
* ZergRush: In-story, individual Waregeists aren't particularly powerful, but they appear in great numbers and don't stop coming. In-game, their nature as {{Asteroids Monster}}s means that if you're not careful, your defensive lines will get overrun by massive numbers of unblockable enemies that you can't kill fast enough to win.

[[folder:Grindstone]]
->'''Other variations:''' Brightmirror

A canine-like Waregeist made from wooden seals. Spawns 2 wooden seals when defeated.

[[folder:Inkwave]]
->'''Other variations:''' Heartbillow

A stone lion-shaped Waregeist created from a fusion of multiple paperweights. Spawns 15 wooden paperweights when defeated.

* MightyGlacier: Not particularly fast moving, but they have good HP and DEF as well as high attack damage.
* ZergRush: Is the epitome of this among Waregeists as they spawn '''15''' paperweights on defeat that requires 2 hits each to kill, making [=AoE=] attacks more or less required to fully clean them up.

[[folder:Fountainboil]]
->'''Other variations:''' Rainbowbrew

A Waregeist made from a tea set resembling a hermit crab with a teapot as its shell. Deals splash Arts damage on attack and explodes upon death to debuff nearby operators with slowed attack speed. Spawns 4 celadon teawares when defeated.

* AchillesHeel: Similar to Infused Originium Slugs, Silence status effect prevents it from exploding on death.

[[folder:Blueflower]]
->'''Other variations:''' Scarletmist

A Waregeist created from a vase that appears as a dragon riding on the vase. Can inflict a debuff that causes operators to take increased Arts damage over time. Spawns a celadon vase when defeated.

* AchillesHeel: Silence status effects prevents the Blueflower from using its debuffing attack as well as freezing the attack count, removing its main source of danger.
* DamageOverTime: After a few attacks, the Blueflower can launch a stronger attack (shown by the attack coming out of the vase instead of the dragon) that inflicts increasing Arts damage over time on the victim.

[[folder:Sinkingsand]]
->'''Other variations:''' Sharpedge

A Waregeist resembling a warrior made from bronze spearheads. Has four "Broken Blades" on spawn, which buffs its attack by 70% and consumes one "Broken Blade" per attack. Spawns spearheads based on the amount of remaining Broken Blades it has at the time of defeat.

* LightningBruiser: It moves slightly faster than the other Power Armors, and, to compensate for its lack of weaponry, possess a relatively fast attack speed.
* MechaMooks: They are completely autonomous.

[[folder:R-31 Heavy Power Armor]]
->'''Other variations:''' R-31a Heavy Power Armor

A set of empty power armor armed with power fists capable of stunning enemies. Can be found sitting inactive in levels, but will become active when they gain enough SP from absorbing Dor enemies.

* GiantMook: It is much taller and larger than the Experimental Power Armor.
* GroundPound: They will punch the ground that leaves Operators stunned.
* MightyGlacier: It is slow as molasses, but hits like a truck, possess even higher HP than the Experimental version, and is capable of stunning unfortunate Operators they can get their hands on.

[[folder:R-11 Assault Power Armor]]
->'''Other variations:''' R-11a Assault Power Armor

A set of empty power armor equipped with rocket launchers, capable of attacking multiple enemies at once. Can be found sitting inactive in levels, but will become active when they gain enough SP from absorbing Dor enemies.

* GiantMook: It is much taller and larger than the Experimental Power Armor.
* MacrossMissileMassacre: They are armed with a missile launcher, and can target up to four Operators present.
* MightyGlacier: Just as slow (and tough) as their R-31 counterparts, but it boasts some firepower in exchange.

!!!Union Army (Introduced in ''Lone Trail'')
[[folder:General]]

* CityGuards: The Union Army soldiers fought in ''Lone Trail'' are the reserve forces stationed in Trimounts.
* TechnologicallyAdvancedFoe: As the primary enemies for ''Lone Trail'', they possess highly advanced tech (only behind Aegir) especially when compared to the other enemies faced before due to their connections with all of the tech companies within Columbia.

[[folder:Trimounts City Defender]]
->'''Other variations''': Trimounts City Defender Captain
Union Army rank-and-file soldiers stationed in Trimounts.

* MovesetClone: For a Normal enemy, they are this to Agents as their attacks will reduce an Operator's block count by one. One major difference is that, when attacking an Operator on a Gravity Switch, the block count will be reduced to ''zero''.

[[folder:Arc Commando]]
->'''Other variations''': Arc Commando Captain
Union Army soldiers that operate a jet-pack and armed with a directed-energy handgun.

* AirborneMook: Unlike the one-use jetpack used by Reunion, the Arc Commandos' jetpack is fully functional. This allows them to easily pass over Operators, similarly to a Dublinn Flying Soldier, and prevent melee Operators from attacking them.
* EnergyWeapons: They come equipped with a handgun that fires direct-energy rounds, courtesy of the Project Horizon Arc.

[[folder:Arc Screenguard]]
->'''Other Variations''': Arc Screenguard Captain
Muscular and imposing Union Army soldiers, donning an experimental unit that grants them formidable defenses.

* AchillesHeel: Fast attacking Operators, their DEF and RES are impressive, but their effectiveness will be reduced if attacked. Operators with a significantly Low ATK Interval can easily break them like a biscuit.
* FlawedPrototype: Their experimental armor; it grants them powerful defenses, yes -- however, their DEF will be reduced everytime they are attacked.
* StoneWall: For a Normal enemy, they boast an ''extremely high'' DEF. So unless they are attacked repeatedly, they can tank through blows and allow their allies to pass through.

[[folder:Arc Frontier]]
->'''Other variations''': Arc Frontier Leader
Elite Union Army soldiers equipped with a powerful laser sword and cutting-edge equipment.

* AchillesHeel: Being shifted. They can easily slay Operators thanks to their equipment, but whenever they are push or pulled, they take a good chunk of their health. Combine this with their weight, and anyone with the strongest shift can easily kill them outright.
* FlawedPrototype: Shared with the Arc Screenguards, but the most blatant. Their equipment is top-tier and wield an equally deadly sword, however they will take a good amount of damage whenever they are pushed or pulled.
* LaserBlade: Armed with a cutting-edge laser sword, that deals Arts damage, made with pure technology and science.

[[folder:"Offender" Production Model]]
->'''Other variations''': "Offender" Prototype
A UGV (Unmanned Ground Vehicle) developed Volvort Kochinski for the C.U.D.O.D. (Columbian Union Department of Defense).

* LogicalWeakness: Like most Machina, they take extra damage from Arts damage. However, they are notable as they possess ''zero'' RES, making Arts damage a serious problem for them.
* MechaMooks: They are completely unmanned.

[[folder:"Crossroads" Production Model]]
->'''Other variations''': "Crossroads" Prototype
Unmanned Defense units developed by Volvort Kochinski for the C.U.D.O.D. (Columbian Union Department of Defense).

* IncreasinglyLethalEnemy: Their lasers deal very low damage, to compensate, they can fire in all four cardinal directions. The closer they get the more damage Operators will take, and once they are closest it will deal full damage.
* NoSell: They cannot be shifted, and they simply pass through even Defender Operators (unless their block count is four through certain abilities).

[[folder:"Traffic Tower" Production Model]]
->'''Other variations''': "Traffic Tower" Prototype, "Traffic Officer", "Traffic Officer Captain"
Humanoid pilot-assisted combat robot developed by Volvort Kochinski for the C.U.D.O.D. (Columbian Union Department of Defense).

* AchillesHeel: Continuously being attacked, shared with the Arc Screenguards. Their DEF is insanely high but damaging them will reduce its durability, and Operators with a significant low ATK interval can easily break their defense.
* GlowingEyesOfDoom: The "Traffic Tower" Pilots' eyes curiously glow once they are ejected from their armor, signifying their intent for an all-out-attack.
* MajorInjuryUnderreaction: Despite the pilot being forcibly ejected (via through the wreckage) and clearly show signs of having [[ClothingDamage damage to their uniforms and helmets]], they don't seem to be particularly injured (as they start with full HP) and are capable of sprinting.
* ShedArmorGainSpeed: Once their robotic suit of armor gets destroyed, their pilot will jump from its wreckage and will sprint towards the Protection Objective.
* TheSneakyGuy: The "Traffic Tower" pilots are invisible, and ranged Operators will not target them unless they are blocked or detected.
* SuperiorSuccessor: To Rhine Lab's Assault Power Armor; compared to the blocky build of the RL counterpart, VK's "Traffic Towers" possess a sleek, streamlined look, boasting arm-mounted cannons from the get-go, and an incredibly insane amount of DEF. The one thing that prevents it from completely trumping the Power Armor is that their DEF lowers whenever they take damage.
