History Characters / KanColleSeven

The personification of the light cruiser USS ''[[http://en.wikipedia.org/wiki/USS_Honolulu_(CL-48) Honolulu]]''. She was introduced as the completion reward for the E-5 map of the Spring 2021 Event.

!!Honolulu (CL-48)

* GratuitousForeignLanguage: She peppers her speech with basic phrases of Hawaiian.
* HardDrinkingPartyGirl: She has a rather outgoing, enthusiastic personality and, over the course of her late night and early morning hourly lines, has enough drinks to give herself a hangover.
* OralFixation: Her default art has her chewing and popping bubble gum. In her Secretary lines, she even offers some to The Admiral.

* CastHerd: The American ships can generally put into several groups: The Main Carrier Task Force (Iowa, Saratoga, Intrepid), Taffy 3 (Gambier Bay, Samuel B. Roberts, Johnston), [[MultinationalTeam ABDACON]] (Houston, De Ryuter, Perth), and the forces at Guadalcanal (Fletcher, Atlanta, South Dakota, Hornet, Helena, Washington, Northampton). American ships generally only interact with members of their group and certain Japanese ships.

The personification of the light cruiser USS ''[[http://en.wikipedia.org/wiki/USS_Honolulu_(CL-48) Honolulu]]''. Se was introduced as the completion reward for the E-5 map of the Spring 2021 Event.

--> ''"Nice meeting you. First of the Northampton-class, Northampton, here. You're the Admiral? Shall we?"''\\\

* ThemeNaming: US battleships are named after American states (Iowa, Colorado, Washington, South Dakota); cruisers after cities and towns (Houston, Atlanta, Helena); destroyers and destroyer escorts after late servicemen (Samuel B. Roberts, Johnston, Fletcher); carriers after old ship names and famous battles (Intrepid, Saratoga, Hornet); escort carriers after bays, sounds, rivers and islands (Gambier Bay); and submarines after marine creatures. There are exceptions, of course.

* LocationThemeNaming: The light and heavy cruisers are named after American cities, while the battleships are named after American states.[[note]]The ''[[https://en.wikipedia.org/wiki/Alaska-class_cruiser Alaska]]''-class cruisers fell under the cruiser naming nomenclature as during WWII, both Alaska and Hawai[='=]i were still considered territories of the US and haven't gained statehood yet.[[/note]]

* MustHaveCaffeine: Helena, Houston, Colorado, Hornet, and South Dakota mentions serving coffee to the admiral in both their married secretary and hourly lines. It's both parts SeriousBusiness and a running joke that coffee is the lifeblood of the American military (since the American Civil War, at that), much like how tea is SeriousBusiness for the British military.

!The Abyssal Fleet

The opponents faced by the player's fleet. The game itself says little about their origins, but the print spin-offs put forward the idea that they are an ''alien'' menace, and what's more are utterly hostile to humanity as a whole, plaguing the world's shipping lanes with unprovoked attacks.

While popular fan theory posits that the Abyssals, particularly its more humanoid members, are actually just turned Fleet Girls like your own playable ships, hints in the Summer 2014[=/=]Aleutians-Midway Event add even ''more'' speculation fuel [[spoiler:as it's obliquely hinted through their lines that the Midway Princess and the Carrier Princess are dark reflections of Akagi and Kaga, respectively. The 2014 Fall Event in Western New Guinea implies that Aircraft Carrier Water Oni is Shoukaku's dark side]]. Players familiar with the Shin Megami Tensei: Persona franchise, particularly with VideoGame/{{Persona 4}}'s Shadows, found grim humor at this implication.

!!Universal Tropes
* AnimateInanimateObject: While not really appearing as enemies, some of the [=CGs=] shows some objects what have been Abyssalified. Submarine Princess' artwork shows her with two living torpedoes, Z3's Summer 2016 damaged artwork shows her being creeped up by a living naval mine with tentacles, and Escort Water Princess has her accompanied with living lifebuoys.
* BlandNameProduct: Some of the equipment used by them, like the [[https://en.wikipedia.org/wiki/Grumman_F6F_Hellcat "Cat Fighter"]] and [[https://en.wikipedia.org/wiki/Grumman_TBF_Avenger "Revenge Torpedo Bomber"]]... well, it doesn't take a genius to see why many players think the Abyssals represent the Allies.
* BodyHorror: Some of the smaller or weaker Abyssal Ships are disturbing, to say the least. Fanon WildMassGuessing has the knack of taking this to FridgeHorror levels.
* DepartmentOfRedundancyDepartment: Since the ships do not have official individual names (like Kongou, Kirishima, etc.) when their name and class are used together to refer to them, this scheme ends up having stuff like Battleship "Battleship Princess" being common.
* EeriePaleSkinnedBrunette: The dark haired Abyssals.
* EldritchAbomination: They're definitely alien, particularly the starter opponents.
* GameplayAndStorySegregation: For some unknown reason, the ones based on airfields (which are islands) besides Harbor Water Demon and Anchorage Water Demon have existent (albeit low) Evasion stats. How does an ''island'', a '''completely''' stationary object, evade gunfire?
** Taken even further starting from Winter 2016 Event, as defeating the boss in an event map would clear off the red mist off the map, thereby implying it had been freed from Abyssal's influence. When you visit said map again after clearing it, [[UnexplainedRecovery the mist are still there]], and so are the Abyssals.
* GrayscaleOfEvil: They're all white-skinned, wear white or black hair and clothing, have mechanical parts in black or dark metallic grays, and are waging war on humankind.
* HumanoidAbomination: There's also obviously something ''off'' about the humanoid representatives of the Abyssal Fleet. The fact that many seem to be hard-wired with weaponry reminiscent of something you'd expect to find in Creator/HRGiger's work does ''not'' help matters.
* MoreTeethThanTheOsmondFamily: Most, if not all, of them incorporate a big pair of chompers in their designs, some of which are hiding [[NestedMouths more rows of teeth]].
* {{Oni}}: Horned Abyssals tend to look like them, Battleship Princess in particular. To support this, the "Demon" in the names of the ships is written in the kanji for "Oni", which has prompted endless speculation since.
* ThePrettyGuysAreStronger: Unlike the clearly inhuman mooks, all ''Demon'' and ''Princess'' ships are [[ItMakesSenseInContext girls with]] [[MechaMooks massive abominations]]. In the original Iroha order, they even progressively take a more human appearance.
* RevenantZombie: Many fans theorize that they [[WasOnceAMan used to be normal shipgirls]] who sank and then got reanimated due to their grudge, akin to the "vengeful ghost" concept. It helps (or perhaps doesn't) that some of the Abyssal bosses look similar to some of the shipgirls. The 4koma also says something along those lines, while [[spoiler:TheMovie spells it out loud]].
* SortingAlgorithmOfEvil: The first Abyssal ships that rookie Admirals will encounter at the start of their careers are comparatively weak Destroyers and Light Cruisers. The further afield they sortie however, they'll soon run into Heavy Cruisers and Carriers, and by the time they hit the end of World 2, they're introduced to the formidable Fleet Carriers and Battleships. When they finally arrive at world 5, "normal" Abyssal ships have mostly given way to [[EliteMook Elite and Flagship versions]], and what's more, an Admiral's fleet will have to face powerful Abyssal ''bosses'' (Demon-class and Princess-class) guarding important nodes.
* {{Stripperiffic}}: Frequently, ranging from 'wearing a thong with no skirt or trousers' to 'wearing a bikini' to 'might as well be wearing nothing at all'. Of particular note here are Ta, Ri, Armored Aircraft Carrier Demon, Southern Ocean War Princess, and Airfield Princess.
** The damaged model of Airfield Princess, which appeared in Summer 2015 event, shows that she is actually wearing a [[LeotardOfPower white leotard]].
* TechnicolorEyes: Generally, how they tell the difference in their ranks. Otherwise, everyone is assumed to have them by default.
** GlowingEyelightsOfUndeath: Every one has glowing eyes, although [[WildMassGuessing there is a lot of guessing that the ships were previously sunken ships]].
** RedEyesTakeWarning: All Elite variants and major bosses have red eyes. They even glow brightly as they attack.
** SupernaturalGoldEyes: Flagship rank, the even stronger variants of common mooks, are denoted by gold eyes.
** GlowingEyesOfDoom: And the most recent introduction of remodeled Flagship rank enemies. One of their eyes glows blue on top of their golden aura.
-->''Music/BlackRockShooter + [[VisualPun Wo-class Kai]] = [[MemeticMutation Black Wock Shooter]]''
* TurnsRed:
** All 3 of the Summer '14 bosses do this when the gauge is one kill from being destroyed. They even receive a bright red glow on them. Especially noticeable on Midway Princess and Aircraft Carrier Princess, whose bodies have glowing veins appearing all over.
** Light Cruiser Oni and Battleship Water Oni in the Winter 2015 have a similar harder form which appears depending on both the completion bar and the difficulty selected.
* UndeathlyPallor: Absolute white skin, which goes along nicely with the GlowingEyelightsOfUndeath.
* WeHaveReserves: For a good reason. The Abyssal fleet seem to never run out of ships, mainly it's common ships... Which often later appear in stronger forms.
* WeWillMeetAgain[=/=]IShallReturn: Some of the enemy bosses will tend to say this, for a good [[DeathIsCheap reason]].
-->''Anchorage'': "I...will return back...To above the blue sea..."
* WhiteHairBlackHeart: The white-haired Abyssals.

[[folder:General Enemy Units]]

The standard Abyssal ships, divided into the same ship classes as the shipgirls. While they lack the variety and personality of the shipgirls, they make up for it with [[WeHaveReserves numbers]].

!Destroyers
!!!I-Class

* AttackAttackAttack: Shown off in the anime. Unlike much of the Abyssals which prefer to lay back and shoot with the cannons from afar, the I-class on more than one occasion go straight up to their opposing fleet and ''shoot them point-blank.''
* TheGoomba: The weakest enemy in the game. However, their Flagship and Late Model version, turn them into GoddamnBats.
* TookALevelInBadass: The Summer 2015 event introduced the fiendishly strong Elite Late Model Kai version, which sports a menacing blood red aura and enough firepower and torpedoes to demolish even heavy cruisers in one shot.
* ZergRush: Both in game and in the anime, I-class are easily the most plentiful Abyss ships and among the weakest.

!!!Ro-Class

%% * SlasherSmile
* TookALevelInBadass: In later events they appear later in their (Elite) Late Model version. As they carry powerful Anti-Submarine equipment that can be a bane to submarines. Like the I-class, it's Elite Late Model sports a menacing blood red aura.

!!!Ha-Class

* CyberCyclops: Resembles a gigantic cyclopean skull or an Oni-mask.
* TookALevelInBadass: In later events they appear later in their (Elite) Late Model version. With addition of the ASW patch, they can perform opening anti submarine attack.

!!!Ni-Class

* CyberCyclops: Shares this appearance with Ha-Class, but without the lower jaw.
* TookALevelInBadass: In later events they appear later in their (Elite) Late Model version.


!!!Na-Class
* TheComputerIsACheatingBastard: Stronger versions have opening torpedo, which no player-usable destroyer has.
* GlowingEyesOfDoom: Has a gleaming purple eyes partially covered in metallic plate. It was uncovered in Late Model versions, making their eyes fits this trope to a T.
* NestedMouths: Has at least two jaws, with a cannon for a tongue.

!Cruisers
!!!Light Cruiser Ho-Class

%% * GodivaHair
%% * [[ManInTheMachine Woman In The Machine]]

!!!Light Cruiser He-Class

%% * ArmCannon
%% * CoolMask

!!!Light Cruiser To-Class
%% * MultipleHeadCase

!!!Light Cruiser Tsu-Class

The strongest regular light cruiser. Their strong AntiAir abilities imply that they represent the US Navy's ''[[https://en.wikipedia.org/wiki/Atlanta-class_cruiser Atlanta]]''-class cruisers.

* AntiAir: They have unique medium ranged dual purpose guns, which some speculate allow them to perform Anti-Air Cut-Ins.
** Which makes them the GoddamnedBats in maps that requires a significant number of carriers, as they can and will turn the skies into a goddamned turkey shoot in their favor.
%% * BareYourMidriff
%% * FashionableAsymmetry
* KingMook: The most powerful Light Cruiser type enemy in the game, they also show up as bosses in some maps, especially those that are restricted to small ships.
* PowerFist: Her arms and hands are gigantic, and make her look quite a bit like [[Music/BlackRockShooter Strength]].

!!!Torpedo Cruiser Chi-Class

* ArmCannon: They also visibly used it in the anime.
%% * BareYourMidriff
* CoolMask: Covers nearly her entire face, with only the mouth and glowing left eye exposed.
* EvilCounterpart: To Kitakami and Ooi, given they were historically the only ships with that classification.

!!!Heavy Cruiser Ri-Class

Your run-of-the-mill Abyssal Heavy Cruisers. With their combination of triple 8-inch main batteries and 21-inch torpedo launchers, they seem to represent one of two classes of [=USN=] heavy cruisers built under the limits of the Washington Naval Treaty, the ''[[http://www.globalsecurity.org/military/systems/ship/ca-24.htm Pensacola]]'' and ''[[http://www.globalsecurity.org/military/systems/ship/ca-26.htm Northampton]]'' classes.[[note]]The [=US=] was the only nation that fielded a triple 8-inch main battery, with everyone else going for singles or twin turrets. While there were five classes of "Treaty Cruisers" (Portland, New Orleans, and Wichita being the other three), the Pensacola and Northampton classes were the only [=USN=] heavy cruisers that were armed with torpedo tubes as built, and even then, those tubes were removed in the mid-1930s, long before the start of the Second World War.[[/note]]

%% * BareYourMidriff
* BoyishShortHair: She might be the only short haired Abyssal so far.
* PowerFist: Wields her ship parts as a pair of gauntlets, one being an ArmCannon and the other the Abyssal Fleet's signature giant maw.
* KingMook: Her remodelled flagship version, often called Black Rick Shooter or BRS which show up as bosses in some maps.
* {{Stripperiffic}}: Easily among the least covered out of all the humanoid Abyssals, though she wears more than others such as the Southern Ocean War Princess whose hair is the only thing covering her breasts, and the Armored Aircraft Carrier Princess who wears nothing -- not even any thigh-highs.

!!!Heavy Cruiser Ne-Class

The strongest of the Abyssal Heavy Cruisers. While they share the same basic armament set up as the lesser Ri-Class (Triple 8-inchers backed up by torpedoes) making them represent the same two classes of [=USN=] heavy cruisers as the Ri-class, their high stats, in particular their high luck, heavily imply they represent the Royal Navy's HMAS ''[[https://en.wikipedia.org/wiki/HMAS_Australia_(D84) Australia]]''.

* BodyHorror: Her cannons are embedded in fleshy tentacles extending out from ''her stomach!''
* BossInMookClothing: The flagship and Kai variants can launch planes and have boss-like stats.
* EvilCounterpart: Of the ''Mogami''-class heavy cruisers, specifically Suzuya.
* HighCollarOfDoom: One that appears to be made of teeth, like Midway Princess.
* KingMook: Of Heavy Cruiser
* PeekABangs: Except her right eye isn't exactly covered by her hair, but by some GreyGoo-like covering.
* WhiteHairBlackHeart: In contrast to the black-haired Ri-class.

!Battleships
!!!Ru-Class

* BossInMookClothing: Her Flagship variant makes her this. She also gain the remodeled flagship variant in Spring 2014, also known as Black Ruck Shooter or BRS just as the Ri-class.
* EvilCounterpart: To slow-speed player Battleships, specifically the ''Nagato''-class.
* LightFeminineAndDarkFeminine: The dark feminine to Ta-Class's light feminine.
* LuckilyMyShieldWillProtectMe: The size and shape of her ship parts resemble massive shields, and she's certainly well protected.
* MightyGlacier: The strongest and tougest regular Abssyal Battleship players will encounter in the game. With each version becoming tougher and harder to kill. Goes UpToEleven with her Kai Flagship version.
%% * SensualSpandex
* WakeUpCallBoss: Her first appearance in 1-3 boss node often comes as a nasty surprise to new players.

!!!Ta-Class

* BadassCape: With a single piece of shoulder armor on the left shoulder.
* BareYourMidriff: Thanks to her small sailor uniform.
* DegradedBoss: First appearing as the flagship of 2-5's boss node, she quickly gets demoted to being flagship of mook nodes or escort to proper bosses.
* EvilCounterpart: To player-controlled fast battleships, like the ''Kongou''-class and Bismarck.
* LightFeminineAndDarkFeminine: The light feminine to Ru-Class's dark feminine.
* SailorFuku: A short one with a thong and no skirt.

!!!Re-Class
[[quoteright:249:https://static.tvtropes.org/pmwiki/pub/images/re_class_8.png]]

The Re-class is something of a mystery, as she matches no Allied ship directly. However, fandom frequently associates her with the 1977 proposed conversion of the ''Iowa''-class battleships, which would have given them an aft flight deck for Harrier jumpjets and ASW helicopters, multiple vertical launch anti-ship missile systems, and retained their forward turrets.

* AHeadAtEachEnd: She has a tail-like extension which had a head at the tip.
* BadassAdorable: Very cute and younger-looking than the other battleships, yet by far the toughest of the non-boss Abyssal ships. Her small size has led to speculation that she represents Taffy 3.
* BossInMookClothing: Her Elite model is encountered as a standard enemy, yet has better torpedoes that the Chi-class Torpedo cruiser, and more and better aircraft slots ''than the Airfield Princess''.
** Keep in mind that she still has ''two more upgrades'', Flagship and Flagship Kai, that have yet to see the light of day. Most players dread the day when these versions show up to [[IncrediblyLamePun wREck]] their fleets.
* TheComputerIsACheatingBastard: Not only can she launch both preemptive and closing torpedoes, which is currently impossible for any player-obtainable battleship, she can also launch seaplane bombers to participate in aerial combat and attack submarines.
* FriendOrFoe: In the ''Girl of the Whirlwind'' manga, when enraged, she'll attack her targets regardless of who or what is in the way. Just ask that poor I-class that got vaporized when it was trying to charge the destroyer shipgirls and crossed into the Re-class' line of fire. This is also why fellow Abyssals stay the hell away from her during their operations.
* LightningBruiser: Able to target submarines and [[MoreDakka participate in every single phase of combat]]. Re-class is the bane of many players.
* MemeticHandGesture: It looks like she's saluting, but [[OhCrap most people]] have interpreted it as a [[ThisIsGonnaSuck "This will not end well"]], [[TitleDrop her own name]], or both.
* NonStandardCharacterDesign: While most of the Abyssals, save for Wo-Class, are covered in machinery and have an evil cyborg vibe, Re has a thick, eel-like tail extending from her lower back that ends in an animalistic head.
** Since her tail bears more design aesthetics of the other Abyssal ships, [[WildMassGuessing some speculate that the tail is the real Re-Class and the cute girl is just a decoy.]]
* NothingUpMySleeve: In the ''Girl of the Whirlwind'' manga, Re-Class has a hidden cannon up her sleeve.
* ScarfOfAsskicking: Fits well for the most powerful standard abssyal ship in the game.
* SlasherSmile: Although some find that her grin looks more cheerful and friendly than malicious or threatening.

!Aircraft Carriers
!!!Light Carrier Nu-Class

* HumanoidAbomination: Its gangling limbs give it the appearance of a stunted or underdeveloped Wo-class.
* TheComputerIsACheatingBastard: The flagship variety can attack at night. Until Fall 2015 introduced Graf Zeppelin, who attacks with guns at night, none of the playable carriers could return the favour.
* TookALevelInBadass: By the Spring Event of 2017, they appear in Elite and Flagship Kai version. As they can now attack further in range (listed as Very Long), they can perform "Opening Anti Submarine attack" making them a big threat in the battlefield.

!!!Standard Carrier Wo-Class
[[quoteright:232:https://static.tvtropes.org/pmwiki/pub/images/wo_class_1.png]]

* AnimalMotifs: She's commonly compared to a jellyfish or octopus.
* AscendedExtra: She was obtainable as a pre-order bonus for the Kantai Collection deck in ''TabletopGame/WeissSchwarz''.
%% * BadassCape
* BossInMookClothing: The remodeled flagship variety, known as Black Wock Shooter. Double points that this variety [[TheComputerIsACheatingBastard can attack at night]].
** In Fall 2016 she gains a variant which carries Medium Bombers.
%% * CombatStilettos
* CompositeCharacter: Wo-class doesn't seem to represent a specific type of RealLife carrier, which many speculated that she might represent several Allied Carriers depending on her form.
* TheComputerIsACheatingBastard: Just like the Nu-class, the Flagship variety can attack at night and at medium damage/orange status. Woe betide an unfortunate admiral whose fleet fails to sufficiently damage a Flagship Wo-class, or one of the later upgrades...
* EvilCounterpart: Speculated to be this to the ''Shoukaku''-class.
* NiceHat: [[MindScrew Or whatever that thing on top of her head is]]. It has a grinning mouth, gun turrets on the side, and tentacles hanging off the botton. Fandom has apparently taken Franchise/TouhouProject [[EpilepticTrees logic]] and assumed it to be detachable as well.
** It is shown in the anime that it contains her planes.
* NonStandardCharacterDesign: Wo has a noticeably organic and alien visual aspect compared to the other Abyssal ships.
* PokemonSpeak: Frequently depicted speaking like this. Otherwise her name is used as a VerbalTic.
* SensualSpandex: Wears a tight bodysuit.
* StaffOfAuthority: Wields what appears to be a walking stick or cane and deals damage by controlling planes.

!Transport Ships
!!!Wa-Class

* BodyHorror: While most of the Abyssal ships are grade-A NauseaFuel, Wa deserves special mention because not only does it look like her head has been removed and replaced, it also looks like she might be ''[[FridgeHorror pregnant]]''.
** Some speculates that they probably carry captured ship-girls... Or worse humans.
* ChainedByFashion: Her arms are [[http://kancolle.wikia.com/wiki/Transport_Ship_Wa-Class securely clamped]] to the larger Abyssal ship she's connected to.
* JokeCharacter: While the Elite and Flagship versions are capable of dealing damage to lighter ships like Destroyers and Cruisers, most Wa-class ships merely serve as temporary distractions.
** LethalJokeCharacter: However, that light damage they deal can sometimes mean the difference between victory and being forced to retreat due to critical damage. They also like to draw fire from your stronger ships that you would otherwise prefer to be aimed at something that can hurt you, like the escorting Ru or Ta battleships.
* PinataEnemy: There is even a daily and a weekly quest to hunt them down.
* StoneWall: They have pathetic firepower, outright nonexistent for the most basic form. However, the basic form has more health than heavy cruisers and the stronger forms are on par with battleships.

!Submarines

* {{Expy}}: All Abyssal subs resemble a StringyHairedGhostGirl rising out of the water and as her hair covers her face, in a manner similar to [[Literature/TheRing Sadako]].
* PeekABangs: Their faces are mostly obscured by their hair.

!!!Ka-Class

* GasMaskMook: Wears what appears to be a scuba diving apparatus.

!!!Yo-Class

%% * [[ManInTheMachine Woman In The Machine]]

!!!So-Class

%% * AbsoluteCleavage
* KingMook: The toughest and strongest of the standard abssyal submarines with a stat to boot.
* MightyGlacier: They have as much HP as your Light Cruisers, but have very low evasion in return which can be a big problem without proper anti-submarine equipment.

!PT Boats

!!!PT Imp Pack
[[quoteright:278:https://static.tvtropes.org/pmwiki/pub/images/pt_imp_pack.png]]

* BodyHorror: While the older one looks otherwise normal, the middle has her gun jammed to the inside of her mouth, forcing it to permanently open, while the youngest doesn't look like she has a normal head inside the helmet.
* EnfantTerrible: They look like ''infants.''
* FragileSpeedster: Even moreso than any other Abyssals, as they have incredible evasion and low HP, and is just one good aim from oblivion. [[LuckBasedMission Good luck on landing a hit on them]], though...
* GamebreakingBug: During the first two days of their implementation, the mechanics that give an accuracy boost to destroyers' guns were not properly implemented, which made the Imps [[DemonicSpiders nearly impossible to kill]] as destroyers were unable to hit them. It got to the point where admirals had to rely on cruiser or battleship secondary guns, or even '''[[DeathFromAbove support airstrikes]]''' ''[[ThereIsNokillLikeOverkill just to take them down]]''.
** After the hotfix, the destroyers can now hit the PT boats... [[LuckBasedMission at about half of the time]]. Thankfully the destroyers can hit them reliably on subsequent events.
* GigglingVillain: If they're attacking, they let out a giggle. You will hear it a lot.
* GlassCannon: Despite their fragility, the stronger forms can do torpedo cut-ins, which are incredibly damaging if they connect.
* GlowingEyesOfDoom: The "eyes" on their helmets (think Wo's headgear) blaze blue and white.
* MiniMook: They're so small and quick to the point where the large caliber guns can barely hit them.
* TerribleTrio: They're always encountered as a trio per enemy unit, which makes them the only {{Mook}} type Abyssal unit that appears in group.
* ZergRush: While they are not that strong or durable, each pack contains three imps and there are usually two or more packs at a time. For example, in Fall 2015 E-3 on Easy mode, there is one node where you can get a battle with a Flagship I-Class and ''five'' PT Imp Packs, what would equal 15 imps in total.

!Coastal Installations

!!!Artillery Imp
The small CompanionCube of Installation-type Abyssal Princess, much like in RealLife where their duty is to protect Naval Bases or Islands such as Wake Island from naval invasion.
----
* BodyHorror: Its entire ''head'' is replaced by a gun turret, and its arms are metal-covered stubs.
* EnfantTerrible: Wears what looks like a metal diaper, and the only exposed body parts are the legs of a baby.
* HeavilyArmoredMook: Unlike other installation-type enemies, they cannot be shotgunned with Type-3 shells, as they are considered hard targets, which Type-3 shells are ineffective against. Rocket barrages with the [=WG42=] ship-to surface rocket launcher will work as usual, while Type 91 [=AP=] rounds will easily defeat their armor. Failing that, equipping your girls with Daihatsu Landing Crafts loaded with infantry and having them storm the bunkers is also a viable choice. They also take vicious damage from Land-based Bombers.

[[folder:Boss Units]]

The most powerful and [[ThePrettyGuysAreStronger human looking]] members of the Abyssal Fleet, these units are for the most part unique and guard specific key locations. Most are based on real-life locations.

* BonusBoss: Any of the Event bosses.
* CameBackStrong: Many of the Event bosses were fought and sunk multiple times during their respective events, growing more powerful each time.
** Taken to new levels by Anchorage Princess, who returned two years after their initial debuts as ultra powerful Water Demon bosses for the Spring 2015 event.
* CatchPhrase: All have at most 10 different voiced lines when encountered. However, they all have some variant of "Sink!".
* TheComputerIsACheatingBastard: Many of them are capable of firing torpedoes ''and'' launching carrier based planes, in addition to having a standard attack, which is impossible for any player controlled ship. Some of the destroyer-types also fire opening torpedoes, which no player-usable destroyer can do.
* DyingAsYourself: [[spoiler:Implied by Midway Princess and Aircraft Carrier Princess's sinking line upon clearing the stage. As they spoke their LastWords, their voices change from the Abyssals' menacing echoes to a soft, human voice, as though they became free from the corruption, this seems to be a trend with the bosses now has all the new bosses since the summer 2014 event also do this for their sinking lines.]]
* EvilIsBigger: As demonstarted in ''Kancolle Arcade'', the Installation Princesses are much (even magnitudes) taller than their seafaring counterparts and the Shipgirls, even the child-like cute-as-a-button Hoppou.
* GodSaveUsFromTheQueen: In ''Kancolle Kai'' credit, they all collectively called the Deep Sea (Abyssal) Queens.
* HornedHumanoid: Many of them have horns, even in places that shouldn't make sense (for example, Airfield and Submarine Princess have horns on their lower back). Takes the whole "[[StealthPun Horned Node]]" to a different level.
* MechaMooks: Unlike the regular abyssal units, which wear their ship weapons on their bodies, the bosses' weapons-at least the ones based on ships as opposed to installations-are represented as massive mechanical beasts.
* MightyGlacier : The Installation-type bosses in general. They're vulnerable to armor-piercing and Type-3 shells and has little to almost no evasion stat, but due to their high armor and invulnerability to torpedoes, as well as how the shell works[[labelnote:*]]The AP shells are only effective on them during the day battle, whereas Type-3 shells deals some but insignificant damage until nightfall, which is when the latter is instrumental in taking down the boss[[/labelnote]], they're fairly difficult to subdue. The fact that the installations are often escorted with a battleship doesn't help matters.
* PunnyName: The ''Demon'' and ''Princess'' characters in their names are all homophone ''ki'', so those who have both Demon and Princess forms have their names pronounced the same (Isolated Island = ''Ritousei-ki''. The ''Water'' suffixes on some of them are likely chosen because ''Sui'' (water) is close to ''Sei'' (purpose-built).
* RapunzelHair: Many of the Demons and Princesses have extremely long hair proportionate to their bodies, often times reaching their ankles. Though this has gotten less frequent with recently introduced bosses.
* TaintedVeins: It seems a mark of a boss unit entering TurnRed phase is their gaining glowing veins or cracks along their skin.
* WarriorPrincess: Princesses are usually stronger than Demons. These Princesses lead Abyssal Fleet and accordingly kick ass. Even Destroyer Princess can shrug off the shelling from battleships and give out even worse beatings in retaliation toward your shipgirls.

First appearing as the boss of Stage 4-4, and returning in maps 5-2 and 5-4, the Armored Carrier Princess is the only Princess that did not debut during a seasonal event.\\\

Given that 4-4 is a stand-in for [[http://en.wikipedia.org/wiki/Battle_of_Madagascar the Battle of Madagascar]], she probably represents the British carriers ''Illustrious'' or ''Indomitable''. On the other hand, given that 5-2 represents the [[https://en.wikipedia.org/wiki/Battle_of_the_Coral_Sea Battle of the Coral Sea]], she could also represent the American carrier ''Lexington''.

* FullFrontalAssault: She's wearing nothing but a very short sailor fuku top, and that gets ripped off entirely in her Princess form.
* SlasherSmile: Sports a particularly vicious smirk in her Demon form.
* TheBattlestar: Sports a 16-inch twin gun mount in addition to her aircraft. [[TheWikiRule The wiki]] even classifies her as an aviation battleship instead of a carrier.
%% * TomboyishPonytail
* TurnsRed: When reduced to 25% health she loses her SlasherSmile and changes from Armored Carrier Demon to Armored Carrier Princess.
* YouHaveOutlivedYourUsefulness: In her Princess form, her Abyssal beast loses its arms and gets split in half, revealing more guns for the Princess to use.

The boss of May 2013 Event Maps 3 and 4. Initially appearing as a Demon, connected to a larger Abyssal Ship, she returns as the Anchorage Princess without it in the next map.\\\

Appears as the first major boss in the anime.

* BadassLongCoat: A black coat in her Demon form, it gets shredded when she turns into a Princess.
* HornedHumanoid: One of the first Abyssal Princess who bares this, which later become a common trend.
* MulticoloredHair: Her hair is predominantly white with black tips.
* StarterVillain: In the anime, she appears and is destroyed in the first episode.
* {{Stripperiffic}}: In her Princess form, because her armor and clothes get torn up.
* TurnsRed: Starts the battle as Demon, attached to a hulking Abyssal ship with massive arms. After taking enough damage, she dumps it, becomes a Princess and attacks you herself.

The boss of August 2013 Event Maps 2, 3 and 4. First appearing as the Southern Demon at the end of Map 2, each progressive defeat sees her [[VillainousBreakdown becoming more crazed and dangerous]]. [[spoiler:Implied to be Yamato's Abyssal counterpart.]]

%% * ArmCannon
* TheBerserker: As seen from how many times she's fought, it makes an impression that she doggedly chasing after the shipgirls with reckless abandon much to her detriment. In the arcade game, her idle animation is roaring to the sky while her shelling animation has her swinging her arms wildly with each shot.
* EvilCounterpart: Her overall appearance as the Southern War Demon is nearly identical to the standard design of the shipgirls.
* {{Expy}}: While she may lack the glowing blue eye, she has Music/BlackRockShooter's outfit and hairstyle.
** Her Ocean Demon form has also been dubbed [[Music/{{Vocaloid}} Abyssal Miku]].
* GlassCannon: Surprisingly has '''10''' armor in War Demon form. This means she can take damage with a very weak hit. [[EpilepticTrees Rumor has it]] that it was, in fact, a typo, supposed to be in the range of 100 (average boss armor is 100.).
* GodivaHair: In her final form. She'd be going FullFrontalAssault if not for some scraps of her metal thong and her hair.
%% * MegaTwintails
* PowerFist: She wears some wickedly sharp metal claws with guns built into them.
* RecurringBoss: She's second only to Battleship Symbiotic Princess in number of appearances, being fought three times in her debut event, showing up during the Fall 2013 event, and becoming a permanent addition as a boss for Maps 5-3 and 5-5.
%% * SlasherSmile
* VillainousBreakdown: When first encountered as the Southern Ocean Demon, she looks an evil knockoff of the shipgirls. In her second appearance, as the Southern War Demon, her SlasherSmile becomes more manic and she is attached to one of the larger Abyssal ships like the other Demons. By the time she shows up as the Southern War Princess, her smirk is completely gone and she's ditched the large Abyssal ship, but kept all of its guns.

[[caption-width-right:290: ''"You shall sink... to the bottom... as many times... as necessary..."'']]

The boss for the fourth map of the Fall 2013 event. Initially believed to represent [[http://en.wikipedia.org/wiki/Honiara_International_Airport Henderson Field on Guadalcanal]], which was defended by the US Marines under General Alexander Vandegrift, her reappearance in other events as a representation of other Allies-used airfields has clouded the water somewhat.\\\

The event map itself replicates [[http://en.wikipedia.org/wiki/Guadalcanal_Campaign#Battleship_bombardment_of_Henderson_Field the historical bombardment of Henderson Field by battleships Kongou and Haruna]].

She returns as the boss of E-4 for the Summer 2015 event. And she's [[TurnsRed very, very angry]].

* CloudCuckoolander: Very often portayed as this, likely due to her [[SomethingCompletelyDifferent unusual health status names]] in her battle ("minor damage" becomes "confused" for her). Ranges from being TheDitz to [[AffablyEvil just completely weird]].
* ClothingDamage: Only on her Summer 2015 final form
* CombatTentacles: In the anime only, her runways are formed from wriggling threads growing from her back, which solidified into runways for her aircrafts.
* FillerVillain: Her role in Winter Event 2016 is to launch land-based aircraft for one phase and nothing else. This means her only contribution in the map is to take potshots at the shipgirls so they will be in a less optimal condition in the next patrol boat node. It will be a well and good strategy, except one shipgirl that guarantees branching to her node (Kasumi) has AA cut-in in her second remodel that will shoot down all of her planes. The shipgirls are even skipping shelling her node.
* HornedHumanoid: Sports a pair of short, round horns on the side of her head.
* LeotardOfPower: Frequently confused with a ThongOfShielding due being the same color as her skin. Her damaged model in Summer 2015 shows clearly that she is indeed wearing a leotard.
* LogicalWeakness: She takes increased damage from ships equipped with Type-3 anti-aircraft ammunition. While it seems strange at first, it's actually a reference to how [[http://en.wikipedia.org/wiki/San_Shiki_(anti-aircraft_shell) historical Type-3 rounds]] worked.[[labelnote:Explanation]] In essence, they were battleship-grade shotgun shells, scattering a cloud of hot shrapnel on detonation, with the aim of taking out enemy aircraft, except subsequent experience showed that they utterly failed in this role. However they proved ''excellent'' at destroying or damaging ground-based structures, and it was in this function that they were used at Guadalcanal.[[/labelnote]]

The final boss for the Fall 2013 event, where she is faced by the player's forces at Ironbottom Sound. She becomes a recurring enemy from that point on, appearing as an escort for the Isolated Island Demon during the Spring 2014 event, and ''two'' copies of her are part of the counterattack fleet during the Summer 2014 event[[labelnote:*]]Only if the player's HQ level is over 100. Lower level admirals just get one[[/labelnote]]. She shows up again as the boss of the Fall 2014 event's third map and has appeared in the Winter 2015 as the pre-boss for the third and fifth maps and the escort for Battleship Water Demon in the fifth map.\\\

She is (loosely) based from the ''Yamato''-class battleships, albeit with their gun caliber designated as 16-inches to to cover up her actual gun caliber[[labelnote:*]]which is actually 46cm[=/=]18.1 inches[[/labelnote]]. That being said, many people believe that she represents the ''[[https://en.wikipedia.org/wiki/Iowa-class_battleship Iowa]]''-class battleships, since the latter is the closest thing to Battleship Princess as far as [=USN=] stand-in goes.

* BadassArmfold: Does this in her Kai form.
* BadassCape: Gains a cape in Kai form.
* BigBad or TheDragon: Widely speculated as one or the other for the Abyssal Fleet since her debut, though it slowly wanes as subsequent event features [[PowerCreep even stronger bosses]].
* BoobsAndButtPose: Her Summer form.
* CombatStilettos: While not very clear in her standard form, she is wearing high heels in her Kai form.
* DegradedBoss: Subverted. Since her original appearance, she's appeared several times in regular nodes or as a sidekick to several bosses... but she remains just as dangerous and frustrating every time, if not ''more'' so, often preventing players' fleets from landing hits on the ''actual'' boss of the map.
* TheDreaded: Seeing her picture show up when landing on a new node is usually enough to elicit an OhCrap, even from experienced Admirals.
* HornedHumanoid: Has a pair of short, upward curving horns on her forehead.
%% * LittleBlackDress
* MesACrowd: Following her debut there have been multiple instances of multiple versions of her appearing in the same map, sometimes in a single encounter. [[EpilepticTrees Whether this means there are multiple Battleship Princesses or she simply has the power to duplicate herself is up for debate.]]
* RecurringBoss: She's been encountered no less than seven times, the most of any Abyssal boss.
* SelfFanservice: Her appearances in official artwork tend to depict her as rather [[http://i1.wp.com/otakomu.jp/wp-content/uploads/2016/01/IMG_3803.jpg?w=600 waifish]]. This hasn't stopped fan artists from drawing her healthy and curvy.

[[caption-width-right:290: ''"I told you... not to come... any... closer..."'']]

The boss of the Spring 2014 event. She represents Port Darwin in Australia, [[http://en.wikipedia.org/wiki/Bombing_of_Darwin which was attacked by the IJN on February 1942]]. Considered the weakest of the island[=/=]installation-type bosses introduced in the game events. She made her return as a permanent boss in early summer 2015, where she is the final encounter of map 4-5.

* BoobsOfSteel: Has the second biggest bust of all the Demons and Princesses.
* CoolBigSis: Fanart likes to depict her as being motherly and affectionate to Northern Ocean Princess.
* FemmeFatalons: Her claws are positively ''massive'', although she doesn't use them to fight.
* GentleGiant: Her artworks with Northern Princess teases it, but her appearance in the arcade spells it out loud. She seems to think of her bestial, roaring rigging like a pet, scratching its chin to calm it down at the beginning of a fight and comforting it when they're destroyed in fiery explosion.
* HartmanHips: By far one of her more....noticeable traits.
* HighCollarOfDoom
* HornedHumanoid: A long, curved horn in the center of her forehead.
* LogicalWeakness: See the Airfield Princess' entry.
* MsFanservice: Combined with StatuesqueStunner and HartmanHips, Seaport Hime is a VERY curvaceous woman.
%% * {{Sideboob}}
* SpellMyNameWithAnS: She's called both "Seaport Princess" and "Harbour Princess" among English speaking fans, as both are technically correct translations of her Japanese name.
* StatuesqueStunner: Frequently portrayed as being very tall in fanart. Confirmed in the arcade 3D model. The Abyssal Princesses are larger than the shipgirls and Seaport Princess is about the same height, when ''kneeling''. Her actual height might even taller.
* TurnsRed: Does this is 4-5 when the boss health gauge is down to one segment. Besides getting ClothingDamage in her CG, she also trades her aircraft in for 15-inch guns.

She makes a return appearance as an optional encounter during Summer 2015, before being a permanent boss in World 6-4 as a Princess.

* CleavageWindow: In her Princess form, which is shaped like a heart. Whether or not she has it in her demon from is unclear due to her pose.
* ElegantGothicLolita: She's dressed up in an outfit like this, with a dress and bonnet with lots of frills, all in black.
* FemmeFatalons: Her nails turn into black claws in her Princess form.
* {{Hikikomori}}: Frequently portrayed as such in fanart, thanks to her name.
* HornedHumanoid: Sports a pair of small black horns with red rings on the sides of her head, which get bigger in Princess form. though whether or not they're real or part of her bonnet is unclear. Princess has a third, really small horn in her forehead.

One of the bosses introduced during the Summer 2014 event, encountered first during the initial map of the MI segment, before being fought again during the penultimate MI map. She also appears at the pre-boss node of the Extra Operation, the counterattack on the fleet girl HQ. She shows up again in the Fall 2014, Winter 2015, Spring 2015 and Summer 2015 events. She later returns as an optional encounter in map 6-1.\\\

Both of her incarnations represent USS ''[[http://en.wikipedia.org/wiki/USS_Yorktown_(CV-5) Yorktown]]''. [[spoiler:Her lines also hint that, much like with Akagi and Midway Hime, she's Kaga's Abyssal counterpart.]]

* BareYourMidriff: She wears a bikini in Summer 2017
* BeefGate: She has a history of appearing in the pre-boss node of event maps, where she'll cheerily send Admirals scrambling back home with a heavily damaged ship (or several).
** Thankfully this is no longer the case with the recent events, as she is completely absent from Fall 2015 Event. Though she is stationed at the Carrier Task Force branching route in the final map of Winter 2016 with several [[DemonicSpiders Wo-class flagships]] as a heavy deterrent against said branching route, her route can be skipped entirely by using Surface Task Force, where the Battleship Princess [[MortonsFork assumes this role instead]].

Suffice to say, it didn't work.\\\

She makes a return as the guardian of the northern pre-boss node for World 3-5's Extra Operation.

* AdorablyPrecociousChild: Commonly depicted as such in fanart.
* BadassAdorable: Due to her relative power in-game, and overall popularity.
* CatchPhrase
-->''Leave the Zero behind!''[[labelnote:*]]She's referring to the [[http://en.wikipedia.org/wiki/Akutan_Zero Akutan Zero]], an [=A6M=] Zero that crash-landed in Alaska in July 1942 and was captured by the Americans[[/labelnote]]

* CreepyChild: Being an Abyssal is enough reason, but the way she shifts from monotone when attacked to screaming when attacking is borderline HellIsThatNoise.
* HappyHolidaysDress: As stated above, she's the only abyssal to have holiday CG, with her getting one on Christmas 2014 and Rainy season 2015. Subverted with Fall 2015 fishing event, however: she has CG update...except that said CG has her [[http://kure.kancollewiki.net/images/0/06/Northern_Princess_Saury_2015.png furiously waving her hand]], basically telling the players "I don't have any fish here!

* AbsoluteCleavage: Her outfit is very conservative by Abyssal standards except for her rack spilling out.
* BoobsOfSteel: Sports a generously-sized rack, albeit not as large as Seaport Princess.
* ClimaxBoss: Of the [=AL/MI=] operation and thus, the first season of the anime. The entire operation, which introducing the shiplocking diversion system, is to take her down. Her defeat in the anime is heralded by copious amount of BigDamnHeroes, to reflect the amount of ship girls needed in the operation. In 4koma, the Admiral initially sends her a gift as a WorthyOpponent before Yamato corrects him, thinking that she's the Abyssal's BigBad because of this trope.
* DamageSpongeBoss: Sports 550 HP in her base form and 600 in her final, making her the most durable Abyssal in the game until the introduction of Central Princess.

The final boss of the Winter 2015 and Spring 2015 events. Role-wise, she is meant to represent the ''Iowa''-class battleships that participated in the attack on Truk Lagoon, specifically USS ''[[http://en.wikipedia.org/wiki/USS_Iowa_%28BB-61%29 Iowa]]'' (who sunk Katori) and USS ''[[http://en.wikipedia.org/wiki/USS_New_Jersey_%28BB-62%29 New Jersey]]'' (who sunk Maikaze).

[[spoiler:Her lines hint that she's the Abyssal counterpart to Nagato, what with her reference to the atomic tests of Operation Crossroad.]]

* {{BFG}}: While it wasn't shown in her sprites or given an image on its own, she is equipped with two 20 inch twin cannons, which in metric units is roughly equivalent to 51cm cannons that were planned for the A-150 battleship. Since the largest naval guns to be historically deployed didn't go any further than Yamato's 46cm guns, how she acquired such an absolutely massive gun is anyone's guess...
* ChainedByFashion: She compliments her dress with spiky manacles on her wrists and ankles.

%% * OperaGloves
* OneSteveLimit: Averted. Like Aircraft Carrier Water Demon, she shares a name and appearance with another Abyssal, in this case Battleship Symbiotic Princess, but has enough unique traits to mark her as a separate being, rather than just being a new form of an existing ship.

Debuted in the Spring 2015 event as the boss of E-4. She was originally thought to be a beefed up version of Seaport Princess, but this was proved wrong when the actual Seaport Princess returned as a permanent boss in a later update.

* AbsoluteCleavage: Her very tiny dress has a very large CleavageWindow.
* BloodKnight: She's quite pleased that your fleet is able to give her a good fight.
* BoobsOfSteel: The largest bust in the Abyssal fleet, [[GagBoobs possibly in the game]].
* FaceDeathWithDignity: Her sinking line is her simply admiring the sakura tree, fitting for a Spring season boss.
* FaceOfAThug: She seems to have a perpetual scowl on her face, which fandom has ran with as the scary older relative depiction.
* FemmeFatalons: Each one individually is ''bigger than her torso''.
* HornedHumanoid: A straight, round horn extending from her forehead.
%% * LogicalWeakness: Like all installation type enemies.
* MamaBear: Her considerable power, which rivals that of Battleship-Symbiotic Princess, and her solemn appearance have caused some fans to characterize her as Seaport Princess and Northern Ocean Princess's angry big sister[=/=]mother.
%% * {{Sideboob}}
%% * SpellMyNameWithAnS: See Seaport Princess's entry.
* StatuesqueStunner: Like Seaport Princess, she's very tall.

Debuts in Spring 2015 as the boss of E-5 and appears in one of the routes of E-6. She reappears again in Fall 2015 as an optional boss, escorted by [[MiniMook PT Imp Packs]] this time around.

* AchillesHeel : If you have a submarine in your fleet, she'll keep sending airstrikes against the submarine to little effect, preventing her from attacking any surface ships throughout the day shelling phase, allowing the rest of your fleet to take out her escorts and then blast her into oblivion with Type 3 shells.
* BadAssLongCoat: Has a white one.
* ClothingDamage: Only in her final form
* CombatSadomasochist: She lets out a creepy giggle when hit.
%% * HighCollarOfDoom
* HornedHumanoid: Has a pair of sweeping, antler-like horns.
* LaughingMad: ''Giggles'' whenever she takes damage.
* LogicalWeakness: Like all installation type enemies.
* MulticoloredHair: Has gradient black and white hair.
* TurnsRed: Does this when the gauge reaches kill zone. Like a few others, she drops her Abyssal beast and fights you directly.
* {{Yandere}}: Fans seem to think this due to her way of speaking and her creepy giggles.

A boss introduced during the Summer 2015 event, and the final boss of map E-3. [[spoiler: She is very obviously the Abyssal counterpart of Mizuho, who was introduced during the same update. Fittingly enough, Mizuho is also drawn by the Abyssals' artist.]]

%% * BareYourMidriff
* BodyHorror: Much like Light Cruiser Demon, she's [[HalfTheManHeUsedToBe cut off at the waist]] into an Abyssal maw...[[VaginaDentata except Seaplane's is missing its top jaw and instead shows off its massive writhing tongue]]. Additionally, just below the shoulder her arms terminate into grotesquely long, skeletal looking mechanical arms, ending in [[FemmeFatalons massive claws]].

[[caption-width-right:290:''"How is it? Does it hurt? Does it? That's the real thing... Ahahahaha...!"'']]
!!!'''Voice:''' Creator/AkariKitou

The final boss of Summer 2015. [[spoiler: She is unmistakably the Abyssal counterpart of Teruzuki.]] Historically, she has no obvious World War II parallel, not least because the operation her map is named after never actually happened in real life, but her ridiculous AntiAir stat has drawn comparisons to the late Cold War-era ''[[https://en.wikipedia.org/wiki/Arleigh_Burke-class_destroyer Arleigh Burke]]''-class guided missile destroyers and their [[https://en.wikipedia.org/wiki/Aegis_Combat_System Aegis Combat Systems]].

* AchillesHeel: Her overwhelming defense is linked to the installations scattered throughout the map she is located - the [[https://en.wikipedia.org/wiki/Operation_FS Operation FS]]. Borderline a PuzzleBoss at best and SNKBoss at worst, the island installations throughout the map must be repeatedly attacked in order to gradually whittle down her defense and render her vulnerable, after which she must be subdued before the next daily reset, lest she regain her defense and the player has to stage further assaults to whittle down her defense again to defeat her.
* AntiAir: She has '''390''' in her anti-air stat, meaning any fleet she is in are pretty much impervious to initial airstrikes.
* BareYourMidriff: Which extends high enough to show underboob.
* DegradedBoss: Two years after her introduction, she made her return in Fall 2017 Event as the first boss at E-3, with her armor reduced to around 270s. She still retains her absurdly high AA, though.
* NonstandardCharacterDesign: She is the first humanoid Abyssal to not be drawn by the Abyssals' usual artist. Instead, Yoshinori Shizuma handled the art for her. [[spoiler: In case you're wondering, he also does the art for the ''Akizuki''-class]].
* OddNameOut: The first Princess-tier Abyssal unit whose name isn't based on a ship class or type of installation.
* PuzzleBoss: She initially had very high armour in the event, but by taking out the right minibosses (in other nodes on the map) multiple times you could lower her armour down to manageable levels. One had to hurry, though, as this effect reset at midnight JST every day.
* SeanConneryIsAboutToShootYou: One of her turrets is aiming at you.
* SlouchOfVillainy: Is notably slouched in her chair as shown in her official artwork, all the while smiling menacingly and aiming her guns at the viewer.
* SmugSmiler: Her default expression is a damnable smirk.
%% * ThongOfShielding
%% * {{Stripperiffic}}
* TooManyMouths: No less than four Abyssal mouths surrounding her. [[spoiler: Which also give subtle hints to the source of her extremely high armour.]]

A boss introduced in the Fall 2015 Event as the final boss of map E-2. As that map represents [[https://en.wikipedia.org/wiki/Battle_of_Kolombangara the Battle of Kolombangara]], she might any of the cruisers from under Vice Admiral Walden Ainsworth's command, such as the [=HMS=] ''[[https://en.wikipedia.org/wiki/HMNZS_Leander Leander]]''. Appearance-wise, though, [[spoiler:she is clearly Jintsuu's Abyssal counterpart.]]

* ArmCannon: A massive Abyssal thing replacing her left forearm with turrets and torpedo tubes.
* CowardlyLion: Despite her intimidating opening line night battle prowess, her attack line has a notable shake in it. [[spoiler:It's Jintsuu's night battle line before her second remodel, when she's in her ShrinkingViolet phase.]]
* CoolMask: One that covers everything from the nose up, has a pair of hornlike protrusions, and makes her look like [[VisualNovel/FateStayNight Rider]].
* TargetSpotter: The first abyssal to mount a searchlight.

A boss introduced in the Fall 2015 Event.

* AchillesHeel: Despite her rather intimidating appearance and menacing voice, she ''is'' still a submarine, and as such is just as vulnerable to ASW as any other submarine[[labelnote:*]]She is very resistant to damage in her final form at the highest difficulty, but several players had unknowingly defeated her after defeating the Anchorage Water Demon (which lowers her armor) or without, before her armor reduction mechanic was discovered[[/labelnote]]. Furthermore, she was first encountered in the Combined Fleet, which does not apply the scratch damage cap to ASW at night. Add in the fact that she does not have preemptive torpedo strikes like other submarines[[labelnote:*]]despite being equipped with the same midget submarine that gave the [[DemonicSpiders Battleship Re-class]] their fearsome pre-emptive torpedo strikes[[/labelnote]], and she is considered by many as an AnticlimaxBoss.
* BareYourMidriff: She shows up a in frilly white bikini in Summer 2016.
* BodyHorror: After her armor breaks, she panics and claims that "water is leaking inside". As she's a submarine, it makes sense when she sinks, water leak is even worse than other ships. But if we takes it with the context that attacking sub with depth charges is basically sending shock waves to rupture their armor, the Princess's distress is less the usual damaged lines and more like her ribs are crushed by water pressure.
* CompanionCube: Just like playable submarines, she babytalks her torpedoes. Seeing that those things might be partially sentient, she has more reason to baby her weapons.
* EvilLaugh: She does it in her intro, unless [[VillainousBreakdown you reduced her armor]].
* LargeHam: She is among the hammiest boss so far, especially when she is being attacked. Given her [[StoneWall very high armor]], you'll be hearing her writhing a lot.
* ParasolOfPrettiness: She gains a beach umbrella in Summer 2016.
* RapunzelHair: Her hair is very long, to say the least.
* VillainousBreakdown: After you reduce her armor, she sounds even more crazy.

[[caption-width-right:290:''"The night...is actually...re...ally....scary...isn't it...?"'']]

The final boss of the Fall 2015 event. As that map is a thinly-veiled representation of [[https://en.wikipedia.org/wiki/Battle_of_Vella_Gulf the Battle of Vella Gulf]], she might represent one of the six American destroyers involved. Appearance-wise, she appears to be [[spoiler:the Abyssal counterpart of Hagikaze.]]
----
* AscendedMeme: Fanartists would often draw other Abyssals with their NiceHat detached, such as Wo-class. This Abyssal's art confirms they are detachable.
* EvilLaugh: When attacking.
* FingerGun: Her rigging's left hand is actually a torpedo launcher, with the fingers as the torpedo. This makes her as the Abyssal with the closest rigging equivalent for the shipgirls.
* MultiarmedAndDangerous: She has a pair of large muscular arms protruding from her back.
* NonStandardCharacterDesign: She is one of the few humanoid Abyssals not drawn by their usual artist. [[spoiler:She's drawn by the same person who also draws Hagikaze, who is obtained after defeating her.]]
* PuzzleBoss: As with Air Defense Princess, she had an armor-reduction mechanic, which is triggered by sending enough PT Imp Packs to Davey Jones' locker. The indication that she has had her armor reduced is when she appears without her helmet.
* TragicKeepsake: The blue ribbon she holds. [[spoiler: It's the same ribbon that secures Kaga's muneate, as Hagikaze was Kaga's escort at the battle of Midway and the ship that scuttled her.]]

A boss introduced in the Winter 2016 Event. Based on Mindoro Island, she's the main target of the overall event.
----
* AlternateCharacterReading: Does her name means supply depot or chaining islands (archipelago)? As Mindoro Island was both in Operation Rei-Go, this might be intentional.
* BareYourMidriff: Like many who get summer form, she wears a bikini top with shorts in Summer 2017.
* BraidsOfAction: Very long ones, as she circles it around her neck like a scarf. Might be PrehensileHair too, as she has rigging attached to its end.
* ButtMonkey: As her map and her fight aren't really difficult and Okinami is a drop in her node in Winter 2016, many Admirals set their eyes on her as "bullying" target. She even exasperatedly shouted the attacking shipgirls to just go away already now that her stockpiles are burning.
* TheComputerIsACheatingBastard: She can launch closing torpedoes. Being an installation means that your girls cannot return the favour.
* DamageSpongeBoss: Her base form has '''600''' health, equivalent to Midway Princess in her final form.
** The [[DamageSpongeBoss damage sponge]] is emphasized as her large HP pull means she takes a significant amount of ScratchDamage from destroyers.
** Taken to ridiculous extremes in the Summer 2020 event; she's the first character to break 4 digits HP (maxing out at 2400 HP)
* EvilCounterpart: As a bespectacled logistics manager with subpar combat capabilities, she's essentially the Abyssals' version of Ooyodo.
* LogicalWeakness: In addition to the standard installation-type weakness to Type 3 shells, she also takes greatly increased damage from the [[LethalJokeItem Wurfgerät 42 mortar launcher]] (on top of [=WG42=]'s usual bonus against installation), most likely because she's sitting on a massive pile of fuel and ammunition.
* {{Meganekko}}: The first Abyssal to wear glasses, and of course, they're ScaryShinyGlasses.
* PowerFist: Her hands are covered in gauntlets about as thick as her torso, which main purpose seems to be for an easier transport of her drums. As other official artworks shows, she has regular looking and somewhat dainty hands
* TurnsRed: When her boss gauge is depleted, she gains new artwork and increased stats like other major bosses, but she also loses a massive amount of health, which is the first for boss unit, with more bosses (like Central Princess) getting the same treatment after Supply Depot Hime's introduction.
* WhoWearsShortShorts: She wears shorts in her summer form.

The final boss of the Winter 2016 Event. [[spoiler: Possibly an Abyssal counterpart to Zara, who is the reward for clearing the event, which would make her the first Abyssal to be the counterpart of a non-Japanese shipgirl.]]
----
* [[AbsoluteCleavage Absolute]] [[CleavageWindow Cleavage Window]]: Her hoodie-dress unzips in the front to show off her breasts and midriff, though its mostly obscured by one of her tentacles.
* BodyHorror: Much like Ne-class, her guns are mounted on two tentacles jutting out of her torso.
* ComicallySerious: Other than her damaged art, her expression never really strays from a uninterested flat gaze, even when doing something silly like playing horsies with her own stomach tentacles.
--> ''Rodeo...''
* TheComputerIsACheatingBastard: Despite being a heavy cruiser, she has opening torpedoes, something no player-controlled heavy cruiser has.
* FashionableAsymmetry: Her left stocking is grey and white striped, while her right is just solid white.
* HornedHumanoid: Sports a long black horn on the left side of her forehead and a smaller horn on the right.
* LargeHam: Once she suffers a VillainousBreakdown, she rivals even the Submarine Princess.
* VillainousBreakdown: She sounds very desperate in her final form, losing her smugness and begins to [[LargeHam chew the scenery]].
* ShesGotLegs: Her summer artwork clearly focuses on her legs.
* WhoWearsShortShorts: In her summer form.

----
* ElegantGothicLolita: Much like Isolated Island Demon, though her dress is white with black trim.
* FlowerMotifs: The ''lycoris radiata'', also known as the red spider lily. As can be seen from their boss gauge, the red spider lily is the "national" flower of the Abyssal Fleet.
* HornedHumanoid: Sports two long horns growing from the side of her head.

A boss introduced in ''[=KanColle=] Kai'', representing Pearl Harbour in Hawaii. [[spoiler:She is the Abyssal counterpart to USS ''Arizona'', armed with the same 16-inch [=Mk7=] guns as the USS ''Missouri'', which currently overlooks the Arizona Memorial.]] Like Iowa, she makes her browser game debut in the Spring 2016 Event.
----
* AchillesHeel: Unlike most other installations, she takes a '''massive''' amount of damage from airstrikes, specifically dive bombers. [[spoiler:This is a slight reference to how USS ''Arizona'' was historically sank during the Attack of Pearl Harbor. It wasn't dive bombers that did her in though. She was sunk by torpedo bombers flying at high altitude dropping what were essentially the ''Nagato''-class' 410mm [=AP=] shells from above right onto her deck.]]
* BodyHorror: Her damaged CG depicts her with large sections of her skin missing, exposing her nightmare-ish internals. Even her regular form doesn't really help; she doesn't seem to have a stomach wall, and instead her intestines are spilling out of her belly and connected to her riggings like placental tubes.
* DamageSpongeBoss: Has a whopping 800 HP in ''Kancolle Kai'' on the highest difficulties.
** Her final form in the browser game is even worse, going all the way to 900 HP in E-6 and sporting incredible amounts of armor, the highest of any Abyssal. Unless the player scores a CriticalHit [[LuckBasedMission with initial airstrikes]], sinking her is practically impossible. Things get slightly easier in E-7, where her HP is slightly lower (850 HP in final form) and the player has access to land-based air support, and she gained vulnerability to land tanks.
* FinalBoss: Of ''[=KanColle=] Kai''.
* FullFrontalAssault: She appears to be completely naked.

* AngstySurvivingTwin: The damaged portrait for them shows the black one seemingly crying over the death of the white one.
* DiedInYourArmsTonight: Their damaged portrait shows the black twin cradling the white twin in her arms and crying in anger over it.
* MilitaryMashupMachine: While they are classified as being aviation battleship, there is implication that they are meant to be a ''submersible'' aviation battleship. [[spoiler:Considering that I-13 and I-14 were designed to be submersible carriers, it is basically adding a third type of ship into the mix.]]
* SexyBacklessOutfit: Both of them wear a SailorFuku-like outfit with no backside.
* UselessUsefulSpell: They have a very high Torpedo stat and are equipped with a High-Speed Abyssal Torpedo (mod.2), which ''should'' let them launch opening torpedoes. Both of these are wasted because they're encountered in the main fleet of an Abyssal Combined Fleet, which doesn't participate in any torpedo phases. Subverted in night battles as the torpedo stat is added to her firepower to allow her to deal high damage.

* BadassCape: A big white fur cape partially covering her arms and rigging.
* BloodKnight: Unlike many other Demons and Princesses who wish for nothing but the sinking of player's ship girls, she is more excited about the fight itself. When she is under attack, instead of screaming in pain or begging player's ship girls to stop, she proudly declares that she will never retreat.
* BoisterousBruiser: She always taunts the player ships, even after she gets a VillainousBreakdown.
* FullFrontalAssault: Only slightly better than the Central Princess, she wears nothing from the thigh up save for the cover for her 'sensitive parts'.
* GiantHandsOfDoom: Her main weapon consists of six 12 inch guns in two triple turrets mounted on a pair of gigantic three-clawed robotic arms.

* DamageSpongeBoss: She has 730 HP and even her weakest form has 196 armour, above daytime damage cap, while her toughest has 270, quite close to the night battle damage cap. This means that not much can deal good damage to her.

* PeekABangs: Her right eye is hidden behind her hair.
* RapunzelHair: In addition of being very long, her hair is also very thick.

* BattleBallgown: She wears an armored dress ''[[UpToEleven with naval guns mounted on it]]''.
* BlackSwordsAreBetter: She is holding a black sword loaded into an arbalest which doubles as flight deck.
* CompositeCharacter: Her status as an aviation battleship with 15-inch [[labelnote:note]]converted to cm, it is roughly equivalent to Warspite and Littorio-class's gun caliber, while being only slightly larger than Bismarck and Richelieu's.[[/labelnote]] dual purpose main guns and sonar implies that she is [[spoiler: a composite of the three ships which the [[https://en.wikipedia.org/wiki/Unsinkable_Sam Unsinkable Sam]] was abroad (Bismarck, HMS Cossack and Ark Royal)]].
** Given that her main guns are named "Abyssal 15-inch Late Model Twin Gun Mount" [[labelnote:note]]which looks like [[https://en.wikipedia.org/wiki/BL_15-inch_Mk_I_naval_gun BL 15-inch Mk I naval gun in Mk I turret]][[/labelnote]] and she traded her sonar for torpedoes in her final form, it is also possible that she is [[spoiler: a composite of Ark Royal and a British battlecruiser or battleship mounting such guns]].
* CoolCrown: Wearing a crown ''[[NightmareFuel made of teeth]]'', cementing her LadyOfWar appearance.
* DamageSpongeBoss: Has a whopping 880 HP in her final form, with an armor that is well above 200. Thankfully, after doing a debuff your fleet will engage her with 1.3x damage modifier as long as your fleet secures Air Superiority over her fleet.
* HighClassGloves: A pair of partially torn black [[FingerlessGloves fingerless elbow glove]] with armor plates on left forearm.
* LadyOfWar: Unlike previous bosses, she has this appearance. It helps that she has a dolphin-like mechanical beast as her mount.
* NonStandardCharacterDesign: She appears out of place compared to the other Abyssal bosses, looking like both [[VideoGame/FateGrandOrder Saber Lily]] and something straight out of ''VideoGame/DarkSouls'' at the same time.

!!Event-exclusive ships
!!The Fleet of Fog
During the Fall 2013 Anime season, the anime Arpeggio of Blue Steel aired, coinciding with much of Kantai Collection's rapid rise in popularity and recognition. Naturally, a collaboration between the two franchises was inevitable. It started with a few endcards in the anime with some Arpeggio ships paired with their [=KanColle=] counterparts, and culminated in a crossover event in the [=KanColle=] game running from 24 December 2013 to 8 January 2014. During this time, certain ships from the Fleet of Fog were usable as temporary allied units and certain others acted as enemy, which both types were removed when the event ended.\\\

All ships of the enemy!Fleet of Fog retained their anime voices, had hourly lines The ship library did not include them either. They also retained their personalities, and a number of their lines were references to the anime (although there was no mention of Gunzou).\\\

For the tropes depicting the Fleet of Fog in the Arpeggio anime, please see [[Characters/ArpeggioOfBlueSteel here]]. For the tropes depicting the allied Fleet of Fog, please see [[https://tvtropes.org/pmwiki/pmwiki.php/Characters/KantaiCollectionFive here]].
