The Playable Characters

In General

    The Inklings
Inklings from the first game (left) and the second (right)
Voiced by: Yuki Tsuji
The main race of the games, Inklings are hyper-evolved squid who have the ability to transform between humanoid and cephalopod forms at will, produce gallons of colorful ink, and swim in said ink. Teenage Inklings, in particular, enjoy engaging in friendly turf wars as a hobby and retrieving Golden Eggs from the Salmonids as a freelance part-time job. As the player character is part of this species, you can also add "saving their land from the Octarian army in their spare time" to that list. In the first game, you play as an Inkling with the callsign "Agent 3", while the second game has you as a different Inkling referred to as "Agent 4".

Some tropes listed here (mostly gameplay-related) apply to playable Octolings as well.

  • Action Fashionista: Inklings inevitably collect an impressive amount of fresh outfits to battle in.
  • Badass Adorable: Cute humanoids who can shapeshift into cute squids, who can take on an entire army single-handedly.
  • Bag of Sharing: Once Octo Expansion's story is complete, the Inkling and Octoling characters share a multiplayer inventory, rank progress, and Grizzco pay grade. (Interestingly, though, the smartphone companion app does keep track of how much turf you've inked as an Octoling separately from Inkling turf.)
  • Blood Knight: They mainly care about two things; fashion and ink-based warfare.
  • Book Dumb: Not the brightest cephalopod species to walk on land. Most of them have less-than-adequate mathematic skills, don't venture beyond places they already know, and believe that Octolings are just Inklings with exotic hairstyles. Doesn't mean they aren't good at what they do best; battling and looking fashionably fresh.
  • Boyish Short Hair: The "hippie" hairstyle (the only one available in 1 for girls) is this with huge tentacle sidetails. Also, there's the "haircut" hairstyle, which is introduced in 2, sported by the boxart Inkling girl of that game.
  • Canon Name: At least for the amiibo. The Splatoon Direct showed the name for the orange Inkling Girl as Inky, the blue Inkling Boy as Inked, and the green Inkling Squid as Slippy.
  • Character Customization: The player selects their Inkling's gender (style in 3), skin tone, and eye color. The sequel added customization options for hairstyle and legwear. The main things available for the player to spend their hard-earned money on are weapons and new outfits.
  • Characterization Marches On: A variant. Some round loss animations (with exceptions) from the first game showed Inklings throwing mild tantrums in rage. In the sequel, most if not all of these were changed into signs of dissatisfaction and disappointment, and are more calm and tame overall than the first game's lose animations.
  • Charles Atlas Superpower: During the Inkling Boy amiibo's version of the Final Boss, you can bat back Octavio's Rocket Punches and missiles with the roller. Justified because it's all but stated that it's the ink that sends them back.
  • Child Soldiers: Played fairly straight in Hero mode, where a young Inkling undertakes serious missions against the Octarians singlehandedly. Downplayed in multiplayer, where the turf "wars" they fight are really more like sporting events and are just a cause for a good time. Though they're based on the apparently pretty serious actual turf war fought with the Octarians a century ago.
  • Compressed Hair: The male Inkling's high ponytail and spiked hairstyles and the female Inkling's topknot hairstyle are hidden under hats.
  • Conjoined Eyes: In squid form, their eyes are connected. Octolings don't have this.
  • Cute Little Fangs: All Inklings have two top fangs and one bottom fang down the middle that are meant to represent an actual squid's beak. Many fans have agreed that these beaks make them more adorable and impressionable.
  • Does Not Like Shoes: The Friendship Bracelet gear allows Inklings to go barefoot into matches (despite its name, it's worn around the ankle).
  • Elemental Baggage: Downplayed; their weapons are armed by ink, which is recharged by swimming in it, which is spread by them firing it, which means they essentially have Bottomless Magazines. To clarify, they have an infinitely renewable supply of ink from the finite source they have above its surface.
  • Elemental Hair Composition: Inklings are part-squid, part-ink humanoids. When one's special meter fills up, their hair starts to bubble and waver.
  • Elemental Shapeshifter: Their squid forms can completely merge with their ink, and flow through grates. Rarely for this trope it's an entirely passive ability that needs external implementation to weaponize. It primarily serves as a means of getting around as it's much quicker and more agile than their human form (save for using an Inkbrush).
  • Everybody Hates Mathematics: According to the art book, Inklings are really bad at math and the only reason why Turf War battles remain fair to begin with is thanks to Judd.
  • Failed a Spot Check: Despite being taught about the Great Turf War and their Octarian rivals, the Inklings cannot distinguish an Octoling from their own kind, despite the Octolings having very different eye highlights, octo-hairstyles, and octopus forms. They just see them as "exotic" Inklings that are into weird hairstyle fads. Fortunately, most Inklings like Pearl don't really care if their friends are revealed to be Octolings.
  • The Fighting Narcissist: Inklings have the Downplayed version of this trope as their hat: One Sunken Scroll explicitly calls out Inkling youth culture as singularly obsessed with fighting and fashion, and one of Marie's on-the-spot battle tips is "Remember that losing is temporary, and looking cool is forever." It's for this reason that Commander Tartar grows to absolutely hate them, dismissing them as less than humanity and wishing to wipe them out.
  • Gendered Outfit: In Splatoon, both Inkling girls and boys wear a pair of black shorts with ink-colored stripe on the sides, with the girls' being shorter than boys'.
    • In Splatoon 2, in addition to the above, Inkling (and Octoling) girls have skirt over black shorts, capri denim pants, and loose gym shorts, while boys have yoga pants under shorts, cargo pants with pulled-up leg hems, and knee-length denim shorts. The only new legwear shared between them is yoga pants with ink-colored stripe on the sides.
    • Some clothing have different looks when they're worn by girls (or boys), such as "SQUID GIRL Tunic" and some amiibo gears.
    • Averted in Splatoon 3 where legwears are no longer restricted between genders.
  • Germans Love David Hasselhoff: In-universe, despite (or maybe because of) their rivalry with the Octolings, some Inkings have a fondness for Octoling style attire. And this was even before both races made peace with each other.
  • Glass Cannon: Despite having access to strong weaponry, Inklings (and Octolings) will go down fairly quickly to a well-placed attack, taking between two to five hits with the series's most powerful weapons before they're splatted. Many other tools are capable of one-shotting an Inkling (or Octoling) outright.
  • The Hedonist: As a species, Inklings are mainly just interested in fun, parties, and being stylish.
  • Hello, [Insert Name Here]: The Inkling under your control will always use the name of your current "active" Mii (in Splatoon 1) or the name of your Nintendo Account (in Splatoon 2) for all multiplayer functionality. In single-player, however, the player Inkling is always called Agent 3 or Agent 4. Otherwise Inklings have no canon names, with one possible exception; according to some linked information, the name of the female Inkling on Splatoon 2's cover may be Alice.
  • Heroic Mime: In both games, with Cap'n Cuttlefish and Marie both taking the player character's silence as an affirmative to join the New Squidbeak Splatoon. Lampshaded throughout Splatoon 2, with Marie being a little unnerved about how Agent 4 generally doesn't say a word and just does things, though it is possible to talk with her enough to the point where she gets annoyed by how "needy" you are and refuses to respond.
  • Hyperspace Arsenal: Inklings are capable of throwing bombs, Sprinklers, Splat Walls, planting Squid Beakons and Ink Mines, and pulling Inkstrike missiles, Inkzookas, and Killer Wails out of seemingly nowhere, and many of these things are bigger than they are. The weapon switching scene in single-player mode by Sheldon Requests suggests their weapons are stored in ink.
  • Iconic Outfit: The Inklings have a wide variety of clothing that they can wear, but the box art, promotional materials and Amiibo clearly favor certain pieces of clothing.
    • The first game's Inkling Girl is usually shown with the White Tee, Pink Trainers, and either no hat at all (wearable in-game as Fake Contacts) or the Studio Headphones, and the Inkling Boy is always shown wearing a Zink Layered LS, Purple Hi-Horses, and either no hat or the Pilot Goggles.
    • In Splatoon 2, the girl wears a King Flip Mesh (or no hat), a White King Tank, Mint Dakoroniks, skirt over pants, and the short hairstyle, while the boy wears Squidfin Hook Cans (or no hat), a Black V-Neck Tee, Yellow-Mesh Sneakers, shorts over running tights, and the spiked hairstyle.
  • I Know Madden Kombat: Your Inkling's skill in Hero Mode comes from what amounts to them having played an In-Universe spectator sport. Justified, as said spectator sport and the tools used in it are based upon a historic war of the same name.
  • In a Single Bound: Inklings (and Octolings) can jump really high to land onto one of their teammates, a Squid Beakon, or their own spawn point as a means of transportation.
  • Little Bit Beastly: Inklings are among the most human-looking lifeforms out of all the marine animal denizens, with only the Octolings rivalling that status.
  • Little Miss Badass: Female Inklings, obviously. They're young, cute, and strong.
  • Metamorphosis: At the beginning of their lifecycle, an Inkling starts off as a little baby squid. Gradually as they get older, the squid slowly becomes more humanoid until they reach age of fourteen, settling down with the appearance of a human with squid-like features. They are the trope image for reason.
  • Morphic Resonance: Humanoid-form Inklings have pointed ears and hair-tentacles that correspond to the fins and tentacles of a squid.
  • Oxymoronic Being: They are squid made out of ink, meaning they can't swim in water (and according to Marina, water in general is lethal to creatures made of ink). This doesn't really stop them from having seaworthy boats, swim suits, swimming pools and even water bottles (though at least the swimming pools seem to actually be meant for other species to use, like jellyfish).
  • Puberty Superpower: Inklings don't develop control of their shapeshifting until the age of fourteen. Until then they're working their way up the Sliding Scale of Anthropomorphism all the way to Little Bit Beastly.
  • Purely Aesthetic Gender: Males and females perform exactly alike in battle, so there's no clear advantage to either gender.
  • Rubber Hose Limbs: Completely boneless appropriately enough. The Zipcaster in 3 seems to capitalize on this, allowing Inklings (and Octolings) to use their arms like incredibly stretchy grappling hooks to propel them through the air.
  • Sapient Eat Sapient: Nogami implies in an interview that the salmon fillet sold at Mako Mart might come from Salmonids, who are sapient beings, as the relationship between squid and salmon (In which they predate one another when given the chance) hasn't changed in the world of Splatoon.
  • Secondary Sexual Characteristics: Inkling girls have smaller eyebrows and curvier bodies than boys.
  • Share Phrase: "Booyah!" is the phrase that all Inklings use to shout in happiness. It's part of the mall's name (Booyah Base) at Inkopolis Plaza, and it's the means to power up the Special Weapon appropriately called Booyah Bomb. It is also what the sound "Woomy/Ngyes" refers to, in case you're wondering.
  • Sins of Our Fathers: The Inklings of Cap'n Cuttlefish's time were the victors of the Great Turf War, and subsequently forced the Octarians to live in underground domes which began falling apart a century later. New generations of Octolings were raised to hate the Inklings and prepare for the next inevitable war with them... unaware that the new generation of Inklings see the Great Turf War as ancient history and would welcome their octopus brethren into their society with open tentacles.
  • Slime Girl: And Slime Boys, since their bodies seem to be partially comprised of their own ink.
  • Small Town Boredom: As stated in the first artbook, many of the young Inklings living in Inkopolis are rural migrants who left their hometowns in order to pursue a more stylish and up-to-date life.
  • Sore Loser: Some losing animations in 1 show that they are rather poor sports:
    • With a Shooter, the Inkling face palms, drops their knees, and starts pounding the ground angrily with their weapon.
    • With a Charger, a male Inkling stomps the ground violently, roars while holding their face with their heads, and drops their weapon while facing down. Females stamp their left foot and trip backwards, followed by wiping their faces.
  • Super Drowning Skills: Ironically for beings based on aquatic lifeforms (but not ones composed of ink) they completely dissociate in water. Exactly why and to what extent this applies, however, is quite vague.
  • Super Mode: The Kraken, for any that have it as their special. Ink Armor is somewhat analogous in 2, though the specials in 2 trend away from this generally.
  • Tentacle Hair: They have tentacles as hair in their human forms. They can even be cut just like normal human hair, and don't translate into their squid forms, which is why it's more obvious with characters with longer hair (like most females) than characters with shorter hair (like most males and Marie).
  • Tertiary Sexual Characteristics: In their humanoid form, the only visible differences between Inkling sexes are their "hairstyles". Inkling girls tend to have a pair of "head tentacles" hanging freely, evoking the look of pigtails or really long sidetails, while Inkling boys usually have their tentacles tied up (resembling a topknot or ponytail) or cut short, making them easily hidden by hats. Though it's kind of hard to tell, the males on average do also seem to have much shorter tentacles than the females, which matches real life squid sexual dimorphism. This is averted in Splatoon 3, where any available haircuts can be chosen regardless of gender.
  • Vague Age: The playable Inklings are described as "teenagers", but their age beyond that isn't too specified, beyond Inklings generally gaining full control of their humanoid form at age 14. Interestingly, Agent 4 is noted by Marie as being two years older than Agent 3 was during Agent 3's adventure, meaning the two are currently the same age — and yet, the Inklings of 2, including Agent 4, don't look any obviously "older" than the 1 Inklings.
  • Valley Girl: The female Inklings show some signs of this if the amiibo is of any indication.
  • Voluntary Shapeshifting: Can shift at will between squid form and humanoid form. Downplayed with their retention of squid's general color changing abilities playing into Character Customization.

    The Octolings
Voiced by: Yuki Tsuji
The octopus counterpart of the Inklings, they also have the ability to produce colorful ink and switch between humanoid and cephalopod forms. Initially, they appear as the most elite of the Octarian forces. However, thanks to a certain event in the first game, many Octolings start to integrate into Inkling society in the second. This leads to them becoming playable characters in Splatoon 2 with the Octo Expansion DLC.

Unless noted, playable Octolings generally share tropes with Inklings.
For tropes relating to enemy Octolings, see Octoling (Enemies) tab under Octarians.

  • '80s Hair: Unlike enemy Octolings, the playable Octoling girls' is actually a bit less huge so that it cooperates with hats better, but it's still present despite that.
  • Afro Asskicker: The second hairstyle for playable Octoling boys, which resembles an octopus' mantle.
  • Badass Adorable: They're just as cute, and just as tough, as the Inklings.
  • Badass Baritone: The male voice is much deeper and quieter than a regular male Inkling's voice, fitting to the Octoling's serious demeanor.
  • Bizarre Sexual Dimorphism: Downplayed. While the lower-ranked walking-tentacle-type Octarians can come in both genders (as shown in a picture in the single player trailer), Octolings are only depicted as female in the Inkling-focused single player campaigns in Splatoon 1 and 2. 2's Octo Expansion, however, introduces male Octolings that are just as humanoid as females, and one Sunken Scroll in the first game hinted at this as it showed a younger Captain Cuttlefish and someone who appeared to be a humanoid DJ Octavio. Curiously, though, enemy Octolings remain all-female even in Octo Expansion.
  • Child Soldiers: Octolings are trained and conditioned to serve the Octarian war machine as early as 9 years old.
  • Clark Kenting: Octolings pass themselves as Inklings with weird hairstyles, likely out of fear of Inklings' animosity from the Great Turf War. Pearl and Marina (who is an Octoling herself) enforces this trope and the Inklings buy the excuse, whether they know the truth or not.
  • Contralto of Danger: The female voice is noticeably lower than the female Inkling's iconic high-pitched voice to better fit the Octoling's serious demeanor.
  • Cute Little Fangs: Like Inklings, Octolings have fangs designed to both invoke the image of an octopus beak and be adorable as heck. However, unlike Inklings, Octoling fangs are arranged asymmetrically, with the top and bottom fangs on opposite sides of their mouth.
  • Delinquent Hair: The default hairstyle for Octoling boys is a mohawk... or at least as close as you can get with tentacles, anyway. 3 adds pompadour on top of this.
  • The Engineer: Octolings in general are more interested in technology than their Inkling brethren, often studying their weapons instead of posing with them. This is likely due to growing up in Octarian society, which emphasizes a lot on military tech.
  • Foil: To the Inklings. Inklings are lazy, funny-loving squidkids who like to fight and pose with their weapons. Octolings, on the other hand, are serious, more reserved octokids who prefer to do tech stuff and study their weapons.
  • Fish out of Water: Or octopi out of water, rather. In trying to integrate with Inkling society, the Octolings have a more inquisitive behavior towards the fashion and weapons offered, observed in their different animations.
  • Funny Foreigner: The Octoling amiibo figures give them dialogue. None of them seem to be any good at using Inkling language and talk awkwardly. (The female Octoling says "Boo-yes!" instead of "Booyah!" for example)
  • Hartman Hips: The playable Octoling girls have hips that are rather wide, and this is emphasized by the way they walk.
  • Heel–Face Turn: Over the course of the Octo Expansion, while Agent 8 is trying to escape from the Deepsea Metro, other Octolings who were present at the Squid Sisters "concert" in Splatoon 1 make their way to Inkopolis and begin to try to integrate. Lore-wise, this is the justification for Octolings aside from yourself (i.e. Agent 8) appearing in your plaza. While there are still plenty of hardline Octarians left, it's made pretty clear by chat log 10 that quite a number of Octolings seem willing to give integration a chance.
  • Hotter and Sexier: Deliberately invoked. The devs designed the playable Octolings to look a little older and more mature than Inklings and to also have more sex appeal, with both sexes's default clothes being two-piece skin-tight midriff-baring outfits, their voices being deeper and their damage sounds sounding more sulty and suggestive, and both sexes swaying their hips in a more pronounced way compared to the female Inkling's sway.
  • Little Bit Beastly: Octolings are among the most human-like lifeforms out of all the marine animal denizens, with only the Inklings rivaling that status.
  • Naïve Newcomer: To Inkling culture. Their body language on the equip screens is more inquisitive compared to the laid-back demeanor of the Inklings, and they're notably more reserved and cautious when trying new gear or weapons.
  • Ojou Ringlets: Splatoon 3 adds this as a customizable hairstyle choice for Octolings, with their tentacles swirled up four times on each side.
  • Perpetual Frowner: They don't seem to smile that much.
  • Pretty Fly for a White Guy: Parodied. They try to adopt the Inkling language and slang with rather awkward results.
  • Promoted to Playable: Octo Expansion in Splatoon 2 allows you to play as Octolings for the first time. It consists largely of a new single-player campaign starring an Octoling, and completing it unlocks Octolings for multiplayer as well.
  • Secondary Sexual Characteristics: Like Inkling ones, Octoling girls have smaller eyebrows and curvier bodies than boys'.
  • Sexy Walk: Octoling girls have a tendency of sashaying their hips whenever they walk, but it's not as pronounced when running.
  • Share Phrase: Octolings share the same "Booyah" shout as Inklings.
  • Super Drowning Skills: They swim just as well, which is to say they dissolve in water just as easily, as Inklings.
  • Tertiary Sexual Characteristics: Like Inklings, Octoling haircuts are gender-specific, namely curled tentacles and ponytail for girls, while mohawk and afro are for boys. In Splatoon 3, it's no longer gender-specific.
  • Tsurime Eyes: Played with — the actual shape of Octoling eyes are mostly the same as that of the Inklings, but the eye highlights of the Octolings give the impression of this (as opposed to the domino mask-like rounded highlights on the Inklings).
  • Voluntary Shapeshifting: Like Inklings, the Octolings can transform from humanoids to octopuses and back at will.
  • You No Take Candle: The Octoling amiibos have their dialogue written a broken fashion, fitting as Octolings have a completely different language, and the playable Octolings are currently attempting to integrate into Inkling society and are still learning their language.
    Octoling Girl: Hi, my friend. What is not down?
    Octoling Boy: Hello, my friend. How do the tentacles hang?
    Octopus: ...I am not speaking Inkling good.

Single-player Protagonists

    Agent 3
Voiced by: Yuki Tsuji
The protagonist of Splatoon, this Inkling is recruited into the New Squidbeak Splatoon to protect Inkopolis from the Octarian menace and other similar threats. Agent 3 returns in the sequels as an NPC working with Cap'n Cuttlefish in Octo Expansion, as well as succeeding him as captain in Splatoon 3.
  • Badass Adorable: They're no less cute than rest of the Inklings, but promotional artwork of Female Agent 3, as well as the Octo Expansion, gives them a more reserved and serious demeanor, as well. Remember that Agent 3 has the honor of singlehandedly taking down the Octarian army and their leader in the first game.
  • Badass Armfold: How the Octo Expansion trailer reintroduces them into the game as a Freeze-Frame Bonus.
  • Badass Cape: Agent 3 picks up one of these sometime between the first Splatoon and the Octo Expansion, complete with a tattered end. Naturally, it has the Inkling language version of the number 3 on its back.
  • Big Damn Heroes: Pulls one off in the Octo Expansion when they save Agent 8 and Cap'n Cuttlefish from a blender. Though it's undercut when their own Dynamic Entry ends up accidentally knocking them out.
  • Bonus Boss: Once all the Mem Cakes in Octo Expansion are collected, Agent 8's locker opens to reveal the Golden Toothpick headgear. Examining it reminds Agent 8 of when they fought before they both ended up in the Deepsea Metro.
  • Brainwashed and Crazy: In Octo Expansion, Commander Tartar covers Agent 3 with mind-controlling slime, pitting them against Agent 8.
  • The Bus Came Back: Returns for Octo Expansion.
  • Canon Identifier: Their real name is whatever the player's Mii avatar is called, but they are referred to by the callsign Agent 3.
  • Cutting Off the Branches: While the player character was fully customizable in the first game, Splatoon 2 reveals in Sunken Scroll #2 that Agent 3 is canonically female and light-skinned; promo material for Octo Expansion follows suit for the brief appearances Agent 3 makes. Promo material for the Squid vs. Octopus Splatfest goes against this design, instead depicting Agent 3 as a male Inkling. The Octo Expansion, however, subverts this by allowing you to pick their gender, skin tone, and eye color before they appear, allowing them to match the appearance of your Splatoon 1 Inkling, if you so wish.
  • Gameplay and Story Integration: Mixed with a Call-Back. When you get to define Agent 3's appearance in Octo Expansion, it's limited to what's available in the original game, namely the lack of alternate hairstyles and only 7 eye colors instead of 14.
  • Gameplay and Story Segregation: Despite the Bonus Boss fight seemingly taking place during the Calamari Inkantation "concert" at the time of the first game, Agent 3 still only uses specials from 2 (alongside Autobombs), even though a Sunken Scroll indicates that the new specials wouldn't exist until after that day since they were made after all previous specials were hit with a factory recall. Justified however in that said fight is a Battle in the Center of the Mind for Agent 8.
  • Gender-Neutral Writing: In Octo Expansion, Agent 3 is referred to as "they" even after being customized.
  • The Greatest Story Never Told: Agent 3's achievements and identity are kept secret from the public, as the New Squidbeak Splatoon follows the motto: "The path of the hero is a lonely one." This is the in-universe justification as to why you are treated like a regular Inkling despite saving the Great Zapfish. And to some extent, this is very much the Inkling perspective on events. The Octarians watched the whole thing go down, and Calamari Inkantation being played there is the catalyst for one of the greatest cultural shifts for Octoling-kind since the Great Turf War. It's still a bit unclear how associated Agent 3 is with those events, but at the very least, the Octarian leaders are aware enough of them to send the future Agent 8 after 3.
  • Ground-Shattering Landing: In both of their boss appearances, their Superjumps are always accompanied by Splashdowns.
  • Heroic Mime: They don't get any dialogue but do get a few close ups that give them some personality aside from the player.
  • Hidden Depths: According to the Octo Expansion artbook, they have a side-gig as DJ SANGO®.
  • Iconic Outfit: The Hero Suit, naturally. By the time of their appearance in the Octo Expansion, they're also wearing a tattered Badass Cape adorned with what appears to be the Inkling version of the number 3.
  • Legendary in the Sequel: In the first game, Agent 3 has the abilities of a standard Inkling. Come Octo Expansion, they suddenly have the ability to use unlimited special weapons and feature as the penultimate boss of the main campaign and as the True Final Boss for the DLC as a whole.
  • One-Man Army: They fought the Octarian army with only Cuttlefish, Callie, and Marie as Mission Control. They also prove to be more than a match for Agent 8.
  • The Pig-Pen: When talking to Marie in the second game, she'll mention that Agent 3 didn't have the best hygiene. However, this is only in the west, where as in the original, Marie complimented Agent 4 for having similarly good looks as Agent 3.
  • Previous Player-Character Cameo: The first Splatoon had you play as Agent 3, so they count as this.
  • Put on a Bus: According to Marie, Agent 3 was out on a research trip with Cap'n Cuttlefish during the events of the second game's main campaign. The Bus Comes Back, naturally, for Octo Expansion.
  • SNK Boss: A non-fighting game example. The brainwashed Agent 3 removed the limiter on their weapon, becoming capable of using multiple Specials at a time, charging them up much faster than you can in multiplayer, and in the final phase of the fight, using three Splashdowns in quick succession. They can also dodge-roll despite using a shooter and have an virtually unlimited supply of ink due to their frequent use of specials. They continue using multiple Specials in their Bonus Boss fight, but this time it's set in Agent 8's mind/memories, where they have even better AI, access to Autobombs to keep you on your toes, and even deadlier specials.
  • Took a Level in Badass: Agent 3 has not been idle during the last few years, as both of their boss fights in Octo Expansion will prove.
  • True Final Boss: In a manner of speaking, as Inner Agent 3, Agent 8's perception of them, serves as the final boss for the entire Octo Expansion.
  • Unsportsmanlike Gloating: Octo Expansion: as a boss, Agent 3 will occasionally squidbag you.
  • Weapon of Choice: The Hero Shot, of course. Specifically the one with the design from 1. While Agent 3 could wield the Hero Charger and Roller through the Amiibo challenges, it's the standard Hero Shot that they use the most all the way up to Octo Expansion.

    Agent 4
Voiced by: Yuki Tsuji
The protagonist of Splatoon 2, they are recruited into the New Squidbeak Splatoon by Marie to find the missing Great Zapfish and her cousin Callie.
  • Badass Adorable: They're no less cute than rest of the Inklings, but they have taken on the Octarian menace.
  • Canon Identifier: Their real name is whatever the player's Nintendo Switch Account is called, but they are referred to by the callsign Agent 4.
  • Heroic Mime: Like Agent 3, Agent 4 this is even lampshaded by Marie who finds it creepy that they never say anything.
  • The Greatest Story Never Told: Like Agent 3, Agent 4's achievements and identity are kept secret from the public, as the New Squidbeak Splatoon follows the motto: "The path of the hero is a lonely one." This is the in-universe justification as to why you are treated like a regular Inkling despite saving the Great Zapfish and Callie. Of course, much like Agent 3, this is from the Inkling perspective. Their battle to save Callie took place in the middle of a gigantic concert venue, so the Octarians very much got to watch the entire thing happen.
  • Iconic Outfit: The Hero Suit, naturally.
  • One-Man Army: They fought the Octarian army with only Marie and Sheldon as Mission Control.
  • Pop-Cultural Osmosis Failure: Despite the fact the Squid Sisters were a big deal two years ago, Agent 4 has never heard of them; not even Marie doing her iconic "Stay Fresh" pose rings a bell. Marie is rather disappointed, saying that Agent 4 not "very cultured." The official relationship chart confirms this from Agent 4's point of view.
    Agent 4: She's apparently famous, but you'd have to watch TV to know that.
  • Suspiciously Similar Substitute: They play the exact same role in Splatoon 2's Hero Mode as Agent 3 did in the first Splatoon's. The designs used in promotional material are even pretty similar. Although, they seem far more cheerful than Agent 3.

    Agent 8
Voiced by: Yuki Tsuji
An Octoling who wakes up in a dark subway station with no memories. In the Octo Expansion, they are taken under the wing of a certain old war hero and (hastily) made a member of the New Squidbeak Splatoon. Under his guidance, they have to conquer a series of test facilities while trying to recover their memories, discover the purpose of the facilities, unravel the mystery of the strange green Octarians confronting them and, ultimately, escape to the surface. Along the way, they run into familiar characters from Inkopolis, including an idol duo of no small repute, and a certain Agent of the New Squidbeak Splatoon who played a role in stopping the Octarian forces two years prior...
  • Afro Asskicker: Male Agent 8, a kickass Octoling making his way through the challenging Deepsea Metro, can have this hairstyle.
  • Amnesiac Hero: They wake up in the old subway tunnels underneath Inkopolis with no idea how they got there — or much of anything else, really, aside from a soul-deep call to see the surface, Inkopolis, and the Squid Sisters again. A significant thrust of 100% completion of OE is recovering Agent 8's memories.
  • And Now for Someone Completely Different: In a first for Splatoon, you will actually take control of a character who is not the Inkling you customize when you first start up the game. The story begins when Agent 4 listens in from the subway gate...
  • Badass Adorable: They saved the entire world from certain destruction, yet they are just as cute as the Inklings and Octolings.
  • Bare Your Midriff: Both the female and male outfits are like this.
  • Canon Identifier: Like Agent 4, their real name is whatever the player's Switch Account is called. But since they lost their memories at the beginning of Octo Expansion, they can't recall their name and are thus referred as either No. 10008 or Agent 8.
  • Character Customization: Just like Agents 3 and 4, Agent 8's skin tone, eye color and hairstyle can be edited (though with fewer hair options), with your initial customization happening during the intro of Octo Expansion. Completing the Octo Expansion story mode will make them, essentially, an unlock for your overall multiplayer avatar.
  • Child Soldiers: Like other playable characters, Agent 8's age is never explicitly stated, but they're treated as being the same age as other Turf War sport participants and game protagonists, which would put them around 14 to 16. Octo Expansion makes clear, though, that they were a soldier in the Octarian armed forces prior to the start of the OE campaign.
  • Combat Stilettos: The female Agent 8 wears these throughout the DLC.
  • Cyberpunk: They and their adventure flirt with a lot of the conventions of the genre, and are very "Punk" in general — they're trapped in a gritty, run-down subway system (lit with lots of neon) that has technological hazards intended to kill them and features "old" computing hardware as background elements, they can pull up a projected map of the subway system with a smartphone-like device, they were the apparent subject of biotech experimentation (by a shadowy corporate entity, no less) and are facing down other Octarians who have undergone such, they've been shackled with a number rather than a name, and Agent 8 tromps around in tight black leather and has a remote-controlled kill device strapped to their ink tank at equipment stations while on missions in the subway. Did we also mention that the Metro is overseen by a rampant AI that wants to cause The End of the World as We Know It? The only thing preventing the absolute applicability of the trope is that the tools Agent 8 uses to escape are simply standard Splatoon weapons, which aren't terribly cyberpunk themselves.
  • Darker and Edgier:
    • Not terribly much so — it is still Splatoon, after all — but the default aesthetic for Agent 8 is dark leather and heels, with '80s Hair for Octo-girls and a tentacle mohawk for Octo-boys, as opposed to the casual T-shirt and shorts that Agents 3 and 4 start in.
    • Even in the early parts of Octo Expansion, it's also clear that the story involves biological experimentation on Agent 8 and fellow Octarians, Agent 8 is almost certainly a former child soldier as mentioned above, and the hub for the campaign is a gritty subway system inspired by the appearance of New York City's in the late-'80s/early-'90s, rather than the bright outdoor hubs of the previous single player campaigns.
    • They are also noted as being foils to the Inklings in attitude. While Inklings are lazy and fun-loving, these Octolings are hard-working and serious.
    • The developers added more grim undertones to the game by stating that Agent 8 was at a real risk of dying during the escape portions of the Octo Expansion, and that if the player had failed at any point what happens is that the player goes back in time to reverse said death.
  • Earn Your Happy Ending: Agent 8 was raised in a militaristic environment filled with Octarian propaganda and was raised as a child soldier like other Octolings. Not only that but after defecting they were attacked by Agent 3 and suddenly taken to the Underground Metro where they lost their memories and ended up having to undergo difficult trials just to survive. From their regained memories Agent 8 had longed for a better life on the surface after hearing "Calamari Inkantion", which was still a difficult decision as they had some loyalty to their old friends and DJ Octavio. Despite everything going on Agent 8 was still determined to save the world for both Inklings and the Octarians by stopping the NILS Statue. After everything they have been through Agent 8 managed to finally enter Inkopolis and enjoy the life they had always wanted alongside fellow Octolings who also wanted the same thing.
  • Easy Amnesia: One good spill was all it took for them to lose their memory, but their faculties are otherwise uninhibited. Iso Padre, however, will hint soon after that the fall had nothing to do with the memory loss, and it comes with being trapped in the Deepsea Metro.
  • Eloquent in My Native Tongue: If the amiibos are any indication, their command of the Inkling language is still very much a work in progress, but the Mem Cake poems (which reflect their actual thoughts) are pretty eloquent.
    Octopus form amiibo: I am not speaking Inkling good.
  • Explosive Leash: They have a small bag of cyan ink on the back of their ink tank. This bag will inflate and explode if Agent 8 runs out of time during a Timed Mission or breaks the rules of a stage.
    C.Q. Cumber: <Cause of failure> - test failed.
  • Fashionable Asymmetry: Their outfit has a right sleeve but no left.
  • Gendered Outfit: While their costume are mostly similar, the female's expose more midriff than the male's, have skirt instead of pants, and the female's shoes have higher heels than the male's.
  • The Greatest Story Never Told: Surprisingly, it's a bit unclear if this fully applies to Agent 8 like it does the other members of the New Squidbeak Splatoon. In the main, of course, they do their work in the Deepsea Metro, where nobody aside from CQ, Cuttlefish, and OTH are watching or will know what happened. The grand finale against Tartar, though, takes place slap in the middle of Inkopolis Bay, features a whole fleet of helicopters orbiting the venue, and has you covering a huge statue in ink via massive ink explosions, all while Off The Hook blasts some tunes. It feels a bit incredible that nobody on the shore noticed that happening.
  • Heel–Face Turn: The story states that Agent 8 is an Octoling locked in battle with Cap'n Cuttlefish and Agent 3 when they were ambushed by "someone", and all three got knocked underground. An amnesiac Agent 8 (christened such by Cuttlefish after the fact) now supports the Cap'n in an attempt to escape Kamabo Corp's Deepsea Metro. And by the end of it all, they've saved both Inkling and Octoling-kind.
  • Hell-Bent for Leather: Agent 8's default outfit is a leather ensemble so tight you could bounce a coin off it.
  • Heroic Mime: Like Agent 3 and 4, they don't speak and Cap'n Cuttlefish lampshades it by taking their "stunned silence" as a yes. It is later subverted with the Mem Cakes, which has poem verses apparently written by Agent 8.
  • Hidden Depths: If the Mem Cakes are any indication, underneath one of the Octarian army's former elite soldiers lay a surprising talent for tanka poems.
  • Hotter and Sexier:
    • Again, not that much — it's Splatoon, for cryin' out loud — but female Agent 8 does crank up the suggestiveness dial a bit compared to her Inkling counterparts. There's the outfit, for starters, but a lot of the promo screenshots and whatnot feature Agent 8 (with various eye/skin options) in poses and camera angles that are a bit "sexier" than is typical for Splatoon. 8 also engages in something much more like a Sexy Walk down the platform and train in the trailer than her Inkling counterparts are ever seen doing, in trailers or in-game.
    • The male Agent 8 wears a revealing leather outfit like the female Agent 8.
  • The Knights Who Say "Squee!": They're octo-fighters of no small talent themselves, but the game intro indicates that, much like Marina, part of what motivates Agent 8 is being amazed at the encounter between the Squid Sisters and DJ Octavio back in Splatoon 1 and wanting to reach Inkopolis to see more of Inkling society for themselves; this desire is the one thing they vaguely remember, even after forgetting everything else.
  • Non-Indicative Name: Despite being codenamed "Agent 8," they aren't even connected to the New Squidbeak Splatoon, much less its 8th member. The codename just serves as a short hand for "10008."
  • Memento Macguffin: Completing trials in Octo Expansion gives Mem Cakes, physical manifestations of 8's lost memories. Collecting all of them unlocks their locker in the Deep Sea Metro station, which holds the Golden Toothpick. This one reminds them of their battle with Agent 3 two years ago, which they must relive if they want to collect it.
  • Mistaken Identity: It's apparent from the Mem Cakes that Agent 8 was already planning on leaving the Octarian Army if they didn't leave already. Since Agent 8's turn happened before the memory loss, Agent 8 was probably mistaken for an Octarian soldier by Agent 3 and Capt. Cuttlefish and attacked before they were taken to the Underground Metro.
  • Ms. Fanservice: Or Mr. Fanservice in the case of the male Agent 8. When Octo Expansion prompts the player to choose Agent 8's gender, hair and eye color, and hair style, both genders are nude with only their arms and green goo keeping them from being exposed. Also, like Marina and enemy Octolings, they wear tight leather outfits for much of the expansion.
  • Purely Aesthetic Gender: The Octo Expansion finally introduces Octoling boys into the game, but like the Inklings of the main game, they play no differently from the Octoling girls.
  • Remember the New Guy?:
    • Of a sort. Once you complete Octo Expansion's story mode and get to Inkopolis, the shopkeepers will treat Agent 8 just like Agent 4, and not really have any commentary on them being different. Mr. Grizz, in particular, behaves no differently and still makes his comments as if the Octoling has been employed with Grizzco for some time.
    • Subverted with Pearl and Marina. If you stare at them in their studio, they react in a more familiar manner if you're playing as Agent 8 than they do if you're playing as Agent 4. Justified since Agent 8 becomes a personal acquaintance of theirs in Octo Expansion.
  • Sexy Walk: Rather surprisingly, the female Agent 8 does this prominently when walking down the train in the trailer, with a walk animation very distinct from the Inkling one.
  • Stealth Pun: You're an Octoling. "Octo" is Latin for 8, with the Octo Expansion campaign revolving around this number, with your name just being the tip of the iceberg.
  • Vague Age: They were fighting Agent 3 two years ago and witnessed the final boss battle, but how old they are in the present day is ambiguous.
  • Warrior Poet: They're military-trained, tough enough to make it through the trials, and write poetry in between for each mem cake they recover.
  • You Are Number 6: The Octoling is given the name Agent 8 by Cap'n Cuttlefish, while the identification tags around their ankle and arm denotes them as No. 10008, the 10008th participant in Kamabo Company's Deepsea Metro tests.

    New Agent 3
The protagonist of Splatoon 3, a cephalopod recruited into the ranks of the New Squidbeak Splatoon on their expedition into Alterna. They're given the title of Agent 3, who may or may not have been promoted to being the new captain of the Splatoon.
  • Action Pet: A Smallfry accompanies them, cleaning up the hazardous Fuzzy Ooze and attacking Octarian enemies.
  • Bare Your Midriff: One of their two Hero Suits resembles a tank top that's been slightly torn.
  • Canon Identifier: Like the players before them, they're given a callsign... of Agent 3.
  • Homemade Inventions: In contrast to the more clean glass vial styles of the usual ink tanks, theirs is simply a 2-liter soda bottle with a hose attached.
  • Legacy Character: They hold the title of Agent 3, much as the first game's Player Character did.

People of Inkopolis Plaza

    The Squid Sisters 

Callie & Marie
Voiced by: Yuki Mizutani (Callie, keity.pop), Mari Kikuma/ (Marie), Haruka Shiraishi (both, anime vomic)
An Inkling Idol Singer duo who act as the hosts of the first game, hosting the Inkopolis News Network that announces available stages and modes as well as Splatfest events. Callie is the long, black-tentacled member in pink who is more energetic, while Marie is the short, white-tentacled member in green who is more relaxed.

Two years later, the duo has fallen into relative obscurity, and Callie has mysteriously disappeared. It's then up to Marie and another Inkling to stop the Octarians and find Callie.
  • 15 Minutes of Fame: Downplayed. The duo was very popular in the timeframe of the first game, but two years later, their lack of activity stemming from their separation seems to have caused them to become relatively unknown among the younger Inklings of Inkopolis Square, though Off the Hook's newscast implies that they're still quite famous among the general populace when they expanded to film and television roles. Though of course, Marina holds them in particular regard since they literally changed her life through a performance.
  • Badass Adorable: They may be older than most Inklings, but they're just as cute.
  • Big Eater: Their dialogue points to this often. Not only are they both in love with candy (see Sweet Tooth below), Marie has been known to fantasize about french fries, Callie sometimes interrupts the news to beg the audience to bring her peanut butter, and Marie tells Callie that what she has in common with the Kelp Dome is that they're both "sweaty and full of food." Several of the Splatfests they have hosted across all regions were themed around food items, and one in particular had "eating" as one of the choices.
  • Big Good: With Cap'n Cuttlefish being Put on a Bus, Marie fills this role in the second game's single player.
  • Big Sister Mentor: They both act this way toward Agent 3 when they take over Cap'n Cuttlefish's spot as Mission Control. Marie acts this way to Agent 4 in the second game
  • Boke and Tsukkomi Routine: They fit these roles from time to time, especially during the newscasts. Callie's the Boke, Marie is the Tsukkomi. Appropriately, they support their respective roles in the fifth Japanese Splatfest, which was themed around this routine.
  • Brainwashed and Crazy: What happens to Callie in the second game due to DJ Octavio's hypnoshades. Thankfully she gets better thanks to Marie.
  • Cain and Abel: Due to being brainwashed, Callie serves as the Cain to Marie's Abel in the second game.
  • The Cameo: Marie appears in Octo Expansion in the Bonus Track session of Marina's Chat Room with the username of Agent 2, the text in her ink color.
  • Celebrity Is Overrated: Sunken Scroll #21 in Splatoon 2 sees Callie trying to fight off fans and paparazzi on her way home. The text states that the pressure of fame is getting to her.
  • Characterization Marches On: In the early days of the American English translation of the first game, Marie displayed a liking for marshmallows just like Callie. After the Marshmallow versus Hot Dog Splatfest her lines were edited so that she disliked marshmallows.
  • Clashing Cousins: Used playfully in the Splatfests. They're on opposite sides, however it's (mostly) done in jest.
  • Cold Sniper: Downplayed. Marie isn't evil, or even unfriendly, but her use of a Charger matches her personality as the more reserved, cool-headed member of the duo.
  • Critical Research Failure: In-Universe. Callie has spent years trying to find a Vulpix in her Pokémon Red, not knowing it is not found there and rather in Pokémon Blue. After calling the other version the inferior one, Marie reconsiders giving her a Vulpix.
  • Cute Clumsy Girl: It's implied in some of their conversations that Callie is quite clumsy, such as barely being able to ride a bike, causing multiple accidents back when she worked at Walleye Warehouse, and splatting innocent bystanders during matches, although Marie questions that last one.
  • Damned by Faint Praise: After completing the main story in Splatoon 2, Callie mentions that Marie has been tracking Agent 4 throughout the game and has put together a Agent 4 Factopedia. According to Callie, it's "totally not creepy".
  • Deadpan Snarker: Marie spends a good portion of her dialogue snarking at Callie. Callie also has her moments, too.
  • Does Not Like Spam: Marie was on an anti-pineapple pizza team for a European Splatfest, while one of her lines in Splatoon 2 has her wondering how she can get her hands on a slice of pineapple-free pizza from the future.
  • Does This Remind You of Anything?: A hiccuping Callie asks Marie how to do well in Mahi-Mahi Resort, but her hiccups can easily translate to her being drunk.
  • The Dragon: Callie serves as this to DJ Octavio in the second game while brainwashed.
  • Drives Like Crazy: When Callie expresses a desire to drive one of the forklifts in Port Mackerel, Marie insists she can barely ride a bike. Callie's comment on a cool car she just saw pass by on Urchin Underpass is met by Marie pointing out that she recently failed her driving test.
  • Dub Name Change: From Aori and Hotaru. Some other translations change their names as well, usually to make or keep another sea-related pun.
  • Evil Costume Switch: In Splatoon 2, Callie changes to a much more dark and revealing outfit as a brainwashed enemy to contrast the not-brainwashed Marie who wears a more modest and light-colored kimono. Both end up returning to their original outfits by the end of the game.
  • Exotic Eye Designs: They both have plus sign-shaped pupils.
  • Foolish Sibling, Responsible Sibling: The fourth Japanese Splatfest, Grasshoppers vs. Ants, invokes this dynamic; Callie represents the grasshopper while Marie represents the ant.
  • Genki Girl: Callie is noticeably more energetic and lively than Marie. Especially when her preferred team wins in Splatfests.
  • Graceful Loser: If their preferred team doesn't win a Splatfest, they're disappointed. But they show no hard feelings to each other depending on results (Callie moreso than Marie, however).
  • Hartman Hips: They have some considerably wide hips, accented further by their costumes, especially the puffy bottoms of Callie's shorts.
  • Heel–Face Revolving Door: Even if you beat the Final Boss of the second game, Callie will still return, Brainwashed and Crazy, each time you repeat it. However it's played less seriously after the first time. Turns out Callie keeps putting the shades back on, forgetting the mind control aspect on them (who knows why she doesn't just get someone to remove the mind control bit, really), because she thinks they look good on her. Marie is quite exasperated about it but she'll come for Callie every time.
  • Heroes Love Dogs: Marie supported dogs in the first American Splatfest.
  • How the Mighty Have Fallen: Callie and Marie appear to have shades of this in Splatoon 2. While Callie managed to go on to star in television, Marie on the other hand ended up landing a small-time gig on a radio show that involved studying. (Which in the world of Inklings studying is the very last thing they would care about.) This later comes to ahead when Marie longs for the old days when they were the Squid Sisters. Callie for her part while seemingly successful ended up buckling under the pressure her new fame had gotten her.
  • Idol Singer: They're based on J-pop idols, and they are very popular in the Tokyo-based setting of the game. During Splatfests, they can be seen singing to the plaza crowd on top of trucks.
  • It's Personal: At the end of the NA Splatfest Early Bird VS. Night Owl, Marie's latest win really starts to get on Callie's nerves that they both start bickering (on live TV) about who won the most Splatfests and who won the most important ones. If Callie's Early Birds had won instead, the end result wouldn't have been any better, with Marie's frustration over losing to Callie so often finally boiling over. The next and last Splatfest continues this trend, pitting the Squid Sisters directly against each other.
  • Jerk with a Heart of Gold: Marie. While she's usually bossy, sarcastic, and is a bit of a Competition Freak during Splatfests, under all that snark she genuinely loves her cousin.
  • Jive Turkey: Callie expresses her support for Team Snowman in the Snowman vs. Sandcastle Splatfest by claiming that "Team Snowbae is so fleek that I literally can't even! It's cray. Like...crayfish cray." This ends up alienating Marie from that team.
  • Kindhearted Cat Lover: Callie supported cats in the first American Splatfest.
  • Lame Pun Reaction: Some of Callie's incredibly lame puns cause this reaction from Marie. In one of their conversations, Marie outright says she hates puns.
    Marie: You know how much I hate puns. They're punbearable!
  • Large Ham: Callie, when talking about Museum d'Alfonsino. Marie reprimands her from not using her indoor voice.
  • Lonely at the Top: Leading up to Splatoon 2's release, Nintendo released the story of what happened to them in-between games. They both increased in fame, but their careers went different paths and they started growing apart.
  • Magic Music: Not inherent to them, of course, but Calamari Inkantation can disrupt some of the brainwashing Octarians are subjected to; this is how Agent 8 and Marina Ida got it in their heads to make their own livelihoods.
  • Meaningful Name: In Japan, they're named for two species of squid. In English... well, just say it out loud. During a rematch against Callie in Splatoon 2, Marie is briefly stunned by the revelation after hearing Callie actually say the word "calamari" out loud.
    Marie: Ohhhhh! I just realized that mine and Callie's names... actually, now's not the time.
  • Mission Control: They take over this role in the first game's single player campaign when Cap'n Cuttlefish, their grandfather, is kidnapped. Marie fills this role in Splatoon 2's single player campaign.
  • Modesty Shorts: Marie wears black shorts under her dress, which can be seen when she's dancing during a Splatfest.
  • Ms. Fanservice: Both of them, but especially Callie. Special mention goes to Callie's brainwashed outfit.
  • Nice Girl: Callie is one of the nicest characters in Splatoon. She's optimistic, friendly and a Graceful Loser that doesn't mind being on the loser's side during a Splafest.
  • Nightmare Fetishist: Marie thinks the totem pole faces in Camp Triggerfish are "kinda cute", whereas Callie gets the creeps from them.
  • Non-Indicative Name: While they're related, they aren't literally a Sibling Team. They're actually cousins, as revealed by one of the Sunken Scrolls, and also at at real-life "live" concert.
  • Noodle Incident: In the American Spanish localization, Callie mentions that they got banned from eating at Mahi-Mahi Resort for some reason.
    Marie: You threw that handful of caviar at me first!
  • Not So Above It All: While Marie usually acts as the straight man to Callie, Marie can be pretty silly herself sometimes, such as believing french fries can be grown like plants, and burning her work uniform after quitting a past job at Walleye Warehouse. She even uses a pun when describing Port Mackerel (though not without Callie begging her).
  • OOC Is Serious Business:
    • At the end of the Naughty vs. Nice Splatfest, Marie congratulates Callie for her victory rather than insult her as normal in North American Splatfests. This catches Callie completely off-guard:
      Marie: Congrats, Callie! You earned it...
      Callie: BAHAHA! Whatev— Wait, what?
      Marie: Merry Squidmas from Team Nice!
      (Callie is completely speechless for the rest of the segment.)
    • In the final Splatfest (Callie vs. Marie), Callie calls Marie grandma. The latter is utterly speechless.
  • Paper-Thin Disguise: The game doesn't bother to hide that they're Agents 1 and 2, being the only black- and white-tentacled Inklings in the setting. The actual disguises they wear while communicating with Agent 3 are flimsy at best: Callie wears a beanie and a pair of sunglasses, while Marie wears a green cap and a surgical mask. If you haven't figured it out before Agent 1 accidentally refers to Agent 2 by her real name, then you'll know for sure once that happens.
  • Proper Tights with a Skirt: Marie wears what looks like green tights under her dress, though she also wears shorts.
  • Punny Name: If you put their English names together, they sound like "calamari". It takes two years after the first game for Marie to actually get the joke.
  • Red Oni, Blue Oni: Callie is the red, being more energetic, always leading when discussing the news, and having a mostly magenta color scheme. Marie is the blue, being more laid-back, always responding to Callie's statements, and having a mostly green color scheme. Their solo songs introduced with their amiibo reflect this: Callie's solo, "Bomb Rush Blush", is faster paced and energetic; Marie's solo, "Tide Goes Out", is slower and more chill.
  • Rooting for the Empire: In-Universe. Marie was on Team Decepticon in the North American August 2015 Splatfest. And for the Christmas splatfest in December of 2015, Callie was on Team Naughty.
  • Running Gag: Callie's oft-mentioned inability to ride a bike.
  • Secret Identity: They're Agents 1 and 2 respectively, the player's predecessors in the first game's single player campaign, and Cap'n Cuttlefish's granddaughters. Becomes Late-Arrival Spoiler in Splatoon 2 when Marie flat out admits she's Agent 2 and later talks about her grandfather.
  • Sensible Heroes, Skimpy Villains: Callie's brainwashed appearance is a good deal more revealing than her usual appearance, as she dons a crop top that leaves her midriff exposed.
  • Sexy Backless Outfit: Downplayed. Their outfits show off part of their backs, but they aren't completely backless. Whether or not they qualify for the "sexy" part is for the viewer to decide.
  • Signing Off Catchphrase:
    Callie: Until next time...
    Both: Staaaay fresh!
  • Sinister Shades: In the sequel, Callie wears a pair of sunglasses that cause her to become brainwashed. Upon challenging the final boss after defeating it once, she puts them back on because she thinks they look good on her.
  • Sleepyhead: She's never seen outright dozing off, but Marie's love of sleep is often referenced in dialogue, and she represented Team Sleeping in a European Splatfest.
    Callie: The soothing sea backdrop [of Hammerhead Bridge] makes me want to nap.
    Marie: Everything makes me want to nap...
  • Something Only They Would Say: In the second game, Marie is able to recognize that the mysterious figure intercepting their conversations is Callie all because she's holding the communication upside-down like she did one time in the first game.
  • Sore Loser:
    • Marie, at least in the North American Splatfests.
      After losing Hotdogs vs. Marshmallows: Well played, you sweet-toothed tryhards!
      Losing Art vs. Science: You only won because us scientists have jobs to do.
      Losing Pirates vs. Ninjas: You pirates are a bunch of cheats!
    • Callie calls her out on this after Pirates vs. Ninjas.
      Callie: Avast, me hearties! Sore loser off the port bow!
  • Sudden Sequel Heel Syndrome: Due to DJ Octavio's brainwashing, Callie is on the Octarians' side in Splatoon 2. She snaps out of it by the end, though.
  • Surprisingly Realistic Outcome: After the final boss of the game is defeated the Squid Sisters declare that they have reunited but the post-game dialogue shows that: Callie is still rehearsing her role for a TV show, and Marie is still running her radio program. Despite having reunited they still have obligations to their employers to keep working, and the Squid Sisters still desire to develop their own solo careers.
  • Sweet Tooth:
    • One of Marie's possible lines when the duo introduce Port Mackerel as a playable stage has her wondering if there is candy in the crates with an oddly silly grin on her face.
    • The sisters also always have a cup full of lollipops within arm's reach when you see them hanging out in their studio.
    • In the announcement of the Marshmallows vs. Hot Dogs Splatfest, Callie gets very enthusiastic about the sugary sweetness of marshmallows.
    • In the European version, and originally the North American version too, one of the possible lines for Camp Triggerfish show that Marie is fine with marshmallows too. A bit too much:
      Callie: Ahh, a campsite! Did you bring the marshmallows?
      Marie: I, uh, sort of already ate them. Heh...
    • In the European translation one of the lines for Urchin Underpass has Callie mentioning they did a news story there. Marie states she only remembers it for the ice cream.
    • One of the Japanese quotes for Urchin Underpass has Callie stating she wants a "mega-whip-choco-chip-double-waffle".
  • Tareme Eyes: Marie has softer, rounder eyes to highlight her calmer, more sarcastic personality compared to Callie.
  • Take That!: The Naughty vs. Nice Splatfest has Callie making Marie fall speechless when Callie points out Marie is just as naughty as she is.
    Marie: I'm PLENTY nice, you know! I care about-
    Callie: Yourself? Winning? Insulting me on live TV?
    Marie: (remains shocked for the remainder of the segment)
  • Thicker Than Water: Despite all the tension building between them that led to the final Callie vs. Marie Splatfest (see It's Personal above), they put it all behind them after the results, with Marie acknowledging Callie as her best friend, and Callie acknowledging that her cousin earned her win.
  • Think of the Censors!: In the NA Splatfest for Pirates VS Ninjas, Callie was painfully obviously trying to refer to some other kind of "booty" if Marie warned her about keeping the rating E for Everyone.
    Callie: It's time to swab the deck and plunder the booty!
    Marie: Whoa there, Callie. Let's keep it E for Everyone.
  • Trademark Favorite Food:
    • If one goes by the North American localization, Callie likes marshmallows and catfish burgers while Marie really likes hot dogs (and hot dogfish when Arowana Mall is one of the featured maps)
      Marie: It's the perfect food! Just a cylinder of meat!
    • The Squid Sisters seem to talk a lot about chips (aka fries) in the European version.
    • Callie also seems to like the sundaes they sell at Urchin Underpass.
  • Troll: The U.S. Pokémon Splatfest reveals that Marie did in fact trade Callie a Vulpix... nicknamed BLUEISBEST.note 
  • Tsundere: Marie, towards Agent 4. At the start of the game her lines when talking to her repeatedly include a number of rude thoughts and comments, calling Agent 4 needy and implying that they're bad at multiplayer. By the end of the game, her lines include a number of more friendly ones, such as offering to to get Agent 4 tickets to her next concert, or thinking to herself that Agent 4 is adorable. That's not to say that the original rude lines won't show up anymore.
  • Tsurime Eyes: Callie has sharper eyes to go with her peppier personality compared to Marie.
  • Unsportsmanlike Gloating: Callie engages in a downplayed version after winning the Naughty vs Nice splatfest, and Marie endulges in this after winning the Early Bird vs Night Owl splatfest.
  • Vague Age: They're "at least 17" in S1, and are obviously two years older in S2, but beyond that, nothing is specified. Neither one has visibly aged that much in the Time Skip, although Marie's traditional Japanese outfit does give off a more mature vibe than her usual performance outfit.
  • Walking Spoiler: Callie in the sequel, as her disappearance is what triggers the events of the second game's single-player campaign.
  • Weapon of Choice:
    • Some of their conversations suggest that Marie's preferred weapon is the Charger while Callie's is the Roller. One of their dialogues when Moray Towers is playable outright confirms their choices:
      Callie: Rollers are super effective here!
      Marie: Chargers are the very best, like no gun ever was!
    • When Marie comes in to rescue Callie in the sequel, she's packing a charger which she uses to snipe off Callie's hypnoshades.
  • White Gloves: Both sisters wear these to compliment their outfits.

    Judd the Cat
A cat who oversees Turf Wars and announces the winners. He can be found taking naps in odd places.
  • The Ageless: He was apparently thawed out from a 10,000-year cryogenic suspension 2,000 years before the game starts — and has been judging ink fights ever since. According to Splatoon 2's artbook, he was injected with an immortality drug by his owner.
  • Almighty Janitor: Most Inklings assume that he's just an old stray who judges Turf Wars, but according to the Splatoon 2 artbook, he actually has close connections with multiple world leaders.
  • Fish out of Temporal Water: It turns out that Judd was placed under cryogenic suspension by his owner for 10,000 years following rising sea levels.
  • Heavy Sleeper: When encountered in Inkopolis Plaza or Inkopolis Square and a Splatfest is not going on, he's always asleep and does not wake up. Quite fitting for a cat.
  • Human Popsicle: Revealed to have been put in cryogenic sleep.
  • Intelligible Unintelligible: He only communicates via meows whenever he gives advice, but the Inklings (and the player character) seemingly have no problem understanding what he's saying.
  • Last of Their Kind: He's the last living remnant of human civilization, and quite possibly the last living mammal. Later subverted in Splatoon 2, where a smaller cat companion named Li'l Judd joins Judd in judging matches.
  • Meaningful Name: His name is Judd, and he is the judge of the turf wars.
  • Nonstandard Character Design: Judd stands out as the only character in the first game who isn't aquatic or otherwise amphibious.
  • Pungeon Master: He tends to pepper his dialogue with cat puns (most likely got the habit from his owner 12,000 years ago).
  • Really 700 Years Old: Not including whatever original age he was, he's currently 12,000 years old, although he's only been awake for 2,000.
  • Visual Pun: His distinct markings make him a literal tuxedo cat.
  • Walking Spoiler: His backstory is entirely tied to the spoiler-filled history of the game's universe. Without that, he's just an inexplicable cat in a world filled with terrestrial marine life.

A Jellyfish with a limited understanding of the Inkling language. He manages the clothing shop, Jelly Fresh.
  • Funny Foreigner: Jellyfish have a different language than the Inklings, so Jelonzo tends to mangle his words. It doesn't help that he used a slang dictionary to learn Inkling.
  • Intentional Engrish for Funny: He talks like an old, poorly translated video game.
  • Punny Name: The name of his store is a pun on "Jellyfish" and "Fresh".
  • Put on a Bus: He makes no appearance in Splatoon 2, with his involvement in the birth of Jelfonzo being his only highlight.
  • Rogue Drone: According to the developers, most jellyfish are linked to a Hive Mind, but Jelonzo is one that has managed to develop his own consciousness separate from the collective.
  • Rubber Man: His tentacles can stretch quite far.
  • Truly Single Parent: Jelfonzo was birthed asexually from him.
  • Unlimited Wardrobe: He wears a different shirt every day.

    Crusty Sean
A tiger prawn dressed like a Japanese-style fried prawnnote  and wears shoes on all his legs. He manages the shoe shop Shrimp Kicks in the first game, but has moved on to operating the Crust Bucket food truck in Splatoon 2.
  • Color Contrast: Sean himself has a red body covered with an orangish-brown jacket, while the rest of his outfit consists of blues and purples.
  • Dub Name Change: The Japanese version simply calls him "Rob".
  • Experience Booster: In Splatoon 2, he sells deep fried hot dogs that increase the amount of player experience earned and various drinks that increase the amount of equipment experience earned in battle for 20 matches per food item. Only one boost can be applied at a time and they cannot be combined with the money multipling waffles.
  • Gentle Giant: Tends to scare people due to his height, but is a very kind guy.
  • Has a Type: According to the first artbook, he wants a "small and very cute girlfriend".
  • Hidden Depths: Despite being a rather shallow extrovert, he values his alone time and is something of a filmophile.
  • Let's Meet the Meat:
    • Wears a designer jacket that makes him look like a fried prawn in a rather morbid sense of fashion. It even crumbles like fried batter. Further emphasized by one Sunken Scroll depicting an actual fried prawn meal coupled with a blurb expressing horror that there were once creatures that ate Sean's ancestors.
    • In Splatoon 2, he starts serving various food items that are similar to shrimp tempura. Maybe he got inspired? Marie will clarify that his Crusty Seanwich item is actually a deep-fried hot dog.
  • Money Multiplier: In Splatoon 2, he sells waffles that increase the amount of cash gained from battles for 20 matches. This boost cannot be combined with the other experience boosting food items.
  • Non-Indicative Name: Ignoring the pun, Sean is far from crusty as far as his personality goes. He does however, wear a coat that resembles a crusty coating of fried batter.
  • Punny Name: Say his name fast and you'll get "Crustacean".
  • Status Buff: In addition to his experience and money-boosting food, he sells various drinks that act like equipment bonuses, but are only temporary.
  • Supreme Chef: Marie, Pearl, and Marina all mention that his food is very delicious, and your character reacts positively after eating or drinking anything from him. His food is so hearty that it gives you EXP and money boosts for a few battles.
  • Unlimited Wardrobe: Much like Jelonzo, he changed his shoes daily during his job at Shrimp Kicks.
  • Work Hard, Play Hard: Is described as being someone who works and parties in equal amounts.

    Annie and Moe
Annie is a timid sea anemone while Moe is a loudmouthed clownfish who lives in her "hair". In the first game, they're the managers of the head gear shop Cooler Heads, while in Splatoon 2, the two have moved on to decorating weapons at Ammo Knights and selling customized gear through SplatNet.
  • Anime Hair: Her hair resembles the tentacles of a sea anemone, complete with a resident clownfish.
  • Bespectacled Cutie: Annie's glasses do well to emphasize her endearingly cute Shrinking Violet persona.
  • Flying Seafood Special: Moe somehow manages to float in the air.
  • Jerkass: Moe has a habit of calling Inklings losers or geeks. Nemo he is not. A Sunken Scroll that may or may not reference the two mentions that, either Annie is giving Moe a place to rest, or Moe is manipulating her to do his bidding.
  • No Cartoon Fish: Played with. Moe is depicted as a realistic-looking clownfish, but he does have a colorful personality.
  • No Indoor Voice: Moe always shouts, and very rudely mind you. Every letter in his dialogue is capitalized to emphasize that fact.
  • Punny Name: Annie, Moe, anemone. Not quite "Crusty Sean", but how many anemone puns are there, really?
  • Red Oni, Blue Oni: The loud, brash, and rude Moe is the Red Oni, while the shy and polite Annie is the Blue Oni.
  • Shrinking Violet: Annie is a little bit shy, and fidgets around as you shop.
  • Small Name, Big Ego: Moe always brags about being better and fresher than the Inklings he meets despite being a small clownfish hiding in the hair of Annie. Reaching Level 20 would have him saying "I'M STILL FRESHER!"

The manager of the weapons shop Ammo Knights. He's a horseshoe crab with a love of all things military. His grandfather was an engineer and an associate of Cap'n Cuttlefish.
  • Ascended Extra: Goes from just being the weapon store owner in the first game to being a part of Mission Control in the second. He pulls off this trope again later on when he shows up on the battlefield himself as the driver of Marie's flying truck.
  • Identical Grandson: He looks just like his grandfather.
  • Mission Control: Provides occasional weapon packages (and associated requests) in 2.
  • Motor Mouth: Unintentionally. If you haven't played for a while, he can potentially trap you in lengthy weapon updates that cannot be skipped. Subverted in 2, at least partially; while it's been shown you can't skip them outright, you can fast forward through them. Even Pearl points out that they'll have to listen to him geek out whenever a weapon update is ready.
  • Nerd Glasses: Wears ridiculously thick glasses from staying up all night looking at small weapon parts.
  • No Sense of Personal Space: Marie doesn't know when he may pop up during stage conversations in Splatoon 2 and gets flustered when he does. He hears everything, apparently.
  • No Social Skills: He's such a weapons geek that he'll ramble on and on to people without noticing that they're not necessarily interested in what he has to say, and as mentioned above, he will barge in on conversations whenever he wants.
  • Older Than They Look: He may look like a little boy, but he makes an offhand mention about his car in Splatoon 2, implying he is at least old enough to have a driver's license. He can also be seen in the final boss battle transporting Marie into the battle with a Squid Sisters truck.
  • Punny Name: The name of his shop, Ammo Knights, sounds like "Ammonites" which were prehistoric shelled cephalopods. His own name is obviously a pun on shell.
  • Seldom-Seen Species: Let's just say that horseshoe crabs are hard to find in any media.
  • Voluntary Shapeshifter: Blink and you'll probably miss it, but every time you go into Ammo Knights, he'll quickly transform from crab mode to his humanoid form.

A sea urchin who runs an illegal business in the first game, where he upgrades the abilities of gear in exchange for Super Sea Snails and finds you a replica of a piece of clothing that you see in the plaza. In Splatoon 2, the income he has received from this job has allowed him to retire, and the younger urchin Murch now works for him in filling his previous role.
  • Creepy Good: Spyke has the most creepy aura of everyone else in the plaza, bearing a much more menacing and mature design compared to... well, everyone else. Despite this (and his shady ways of getting gear) Spyke never harms anyone aside from the Super Sea Snails, and is very useful for styling your Inkling.
  • Creepy Long Fingers: His hands are very human-like but elongated enough to give this vibe.
  • Demoted to Extra: In Splatoon 2, Spyke no longer interacts with the player, as his role has been taken over by Murch. Instead, he can be spotted inside a café. Murch does mention Spyke helping when you get your orders that are not exact to how you ordered them.
  • Dub Name Change: Known as "Daunii" or "Downey" in the Japanese version.
  • Friend in the Black Market: Best not to ask where he finds the clothes you ask him to get. His services also don't come cheap, with prices up to three times the store prices of any of the three shops plus what and how many perks they have. The narration of the game itself doesn't want to have you use his services; it tries to convince you to avoid speaking to him.
  • Funetik Aksent: He speaks in a Cockney accent in the North American translation.
  • Not So Above It All: He maintains a serene, detached, and creepy if polite demeanor most of the time, but during Splatfests, he can be seen tapping along to the Squid Sisters'/Off the Hook's tune.
  • Peek-a-Bangs: His "hair" resembles an urchin's shell with one part missing revealing part of his face.
  • Rags to Riches: In the first game he lives in a seedy back alley and makes a living modifying clothes. In the second he appears in a sunken scroll claiming he made one million g's in a single year just by sitting around. Considering how expensive his services are in the first game if you don't have a super sea snail, this isn't surprising. Indeed, Word of God is that he's actually made enough money to retire for life.
  • Street Urchin: He hangs out in an alley sitting on a rug. It actually doesn't get any more literal than this.
  • Technicolor Eyes: As seen in the picture, green irises with purple sclerae.
  • Trademark Favorite Food: Considering that he's surrounded by quivering snails, empty shells and a screwdriver, it's kinda easy to put two and two together. Made even more obvious the first time you talk to him with a Super Sea Snail in your possession, where he says he doesn't need the shell lids that he uses to add/reroll Ability slots, and that "it's just the juicy, gooey stuff on the inside" that he likes.
  • Visual Pun: He's a sea urchin that's also an alley youth, i.e. a Street Urchin.

    Cap'n Craig Cuttlefish
Voiced by: Mahito Yokota
An elderly Inkling who leads the New Squidbeak Splatoon, a militia dedicated to fighting off the Octarian Army.
  • Alliterative Name:
    • Craig Cuttlefish, as revealed in Octo Expansion. His retired rank of Captain gets in on the fun, too.
    • Most other European language versions go for this as well. For example:
      • Dutch: Karel Kraak
      • French: Anastase MacAlamar
      • German: Karl Kuttelfisch
      • Spanish: Jerónimo Jibión
      • Russian: Каракатий Кальмостар (Karakatiy Kal'mostar)
  • Big Good: Serves as this in the first game's Hero Mode.
  • Blue-and-Orange Morality: He's generally inclined to see Octarians as enemies by default, but this is overridden by his firm belief that anyone who likes the song "Calamari Inkantation" can't possibly be bad. This allows him to quickly overcome any objections he might otherwise have to working with Agent 8 or Marina in the Octo Expansion.
  • Boastful Rap: One of the things he likes to do when rapping in Octo Expansion. It's... dubiously successful.
  • The Bus Came Back: Is absent throughout Octo Canyon, but returns in the Octo Expansion to assist Agent 8.
  • Cloudcuckoolander: Was viewed as this by everyone in Inkopolis until the Octarians returned.
  • Distressed Dude:
    • He's captured by DJ Octavio about halfway through Splatoon 1's Hero Mode.
    • He's also captured and tied upside down under a UFO by a Brainwashed and Crazy Agent 3 in Octo Expansion.
  • A Dog Named "Cat": He's a squid named after the cuttlefish, a different order of cephalopods.
  • Doting Grandparent: He's the grandfather of the Squid Sisters, who are also Agents 1 and 2, and their music gives him the strength to break out of his bonds easily. He has taken lessons in rapping in Octo Expansion, making him hyperactive when talking to other characters.
  • Dub Name Change: "Commander Atarime" in Japan, with his full name being "Yoshio Atarime" in Octo Expansion.
  • Enemy Mine: He initially treats the future Agent 8 as just another Octarian foe but realizes that it is better for both of them to call a temporary truce and find a way out of the Deepsea Metro first. Gradually, after learning about Marina's Heel–Face Turn and how "Calamari Inkantation" had positively affected the Octolings, he starts to see Agent 8 as a friend and even hopes that they would be the key to bring Inklings and Octarians together in peace.
  • Hopeless with Tech: The most advanced tech he has is a flip phone that he could text in Marina's chatroom. He uses his real name as a username, has no idea how to turn off Caps Lock when typing until Pearl and Marina tell him where the key is, and manages to text Leet Speak by accident. He's also not up to date with the changes in the weapons, being surprised to learn that chargers can hold a charged shot even submerged under ink, a trait his Bamboozler (and, on that note, all Bamboozlers) lacks.
  • Innocent Bigot: How he comes across when trying to be nice to Octolings. When he meets Marina, he makes a clumsy show of goodwill that includes claiming to "not see species" and complimenting her as being "so articulate".
  • I Was Quite the Looker: Sunken Scroll 15 shows the Captain in his younger days as the leader of the original Squidbeak Splatoon, and he was quite handsome.
  • Long-Lived: He's quite old, if you couldn't tell from his appearance. According to him, he is 130 years old at the time of Octo Expansion.
  • Leet Speak: He does this in Marina's chatroom. And apparently, it's by sheer accident on Cuttlefish's part.
  • Mission Control: In Splatoon's Hero Mode, he communicates with Agent 3 via radio, giving them information about the current Octarian hideout and tips on how to progress. He serves a similar role to Agent 8 in Splatoon 2: Octo Expansion, alongside Pearl and Marina.
  • Passing the Torch: He passes his leadership role on to the original Agent 3 in 3.
  • Put on a Bus: Is on a research trip with Agent 3 during the events of Splatoon 2's base game. He returns for Octo Expansion
  • Retired Badass: He was once as much a fighter as any of the young Inklings, and fought against the Octarians in the past. During the Octo Expansion chat logs, Pearl digs up old war photos of him, and the much younger Inkling is most impressed. He retires again in Splatoon 3, passing the mantle of Captain to one of the former Agents and taking up a patrol role.
  • Sword Cane: Variation. He uses his old Bamboozler from the war as a cane.
  • Trademark Favorite Food: Crabby cakes (biscuits in Europe and Oceania). He likes them so much that he wouldn't stop talking about having some to eat, whether it be in Octo Valley or Deepsea Metro. It proves to be his Fatal Flaw in boss rematches with DJ Octavio in Splatoon 1, where the Octarian leader managed to escape when Cuttlefish was busy eating his crabby cakes.
  • V-Sign: Seen striking it in his promotional character art (and in some concept art as well!)
  • We Used to Be Friends: He and DJ Octavio clearly know each each from times past, and the Sunken Scrolls reveals they were good friends before the first Great Turf War.

People of Inkopolis Square

    Off the Hook 

Pearlnote  & Marina Ida
Voiced by: Rina Itou (Pearl), Alice Peralta (Marina)
The newest freshest Idol Singer duo who reside in Inkopolis Square, with their team called "Off the Hook". They're also the newest hosts for the news. Pearl is the feisty white and pink Inkling rapper, and Marina is the shy black and green Octoling singer and DJ.

In Splatoon 3, they have expanded with three other members to form Damp Socks ft. Off the Hook.
  • Affectionate Nickname:
    • In the English translation, Marina calls Pearl "Pearlie". Pearl, in turn, occasionally calls her "'Rina".
    • In the Japanese version, Marina calls her "senpai".
    • In the Spanish translation, Marina calls her Perlita ("little pearl").
  • Ambiguously Brown: Even though Marina isn't human, her dark skin is something that distinguishes her from other characters.
  • Badass Bystander: When introduced in the Octo Expansion they aren't actually a part of Squidbeak Splatoon, or actively aware of what's going on. Instead they found a communicator that belonged to the Squidbeak Splatoon on a mountain they were visiting, and decided to assist them escaping from the Underground Metro. Instead of taking a backseat, they are active in assisting both Agent 8 and Capt. Cuttlefish and as mission control, Marina being a skilled hacker that can help Agent 8 if they get stuck, and Pearl mobilizing a fleet of helicopters to rescue all members of the New Squidbeak Splatoon at the end. Beforehand Marina also activates Agent 8's emergency beacon in a last ditch effort to prevent Agent 8 and Cuttlefish from being blended, which works when it summons Agent 3 to destroy the blender.
  • Bad Liar: Marina is characteristically nervous and forthright, and so would rather not talk about anything to do with octopuses or her abnormal "hairstyle". Whenever she has to, she tends to do a bad job of covering it up: awkwardly stumbling through words, letting things slip and having to abruptly change the subject. Amusingly, Pearl, who is otherwise far more blunt than Marina, has a much easier time keeping up a cover story than she does.
  • Berserk Button: Marina with certain food and drinks. Pearl claiming ketchup is basically just jam is the first time that we see Marina actually get angry. All she can retort with is "It's not jam." Her rant about mayonnaise implies that condiment is also a button for her, and she's so disgusted by orange pulp that she's too upset about losing that Splatfest to even retort to Pearl's gloating.
  • Big "OMG!":
    • Or rather, "Big 'OMC'", in this case. During the conversation for the Sweaters vs Socks Splatfest, Pearl screams "OH MY COD" when Marina brings up an idea of a sweater with Judd and Li'l Judd howling at the moon.
    • A straight example (just the acronym, though) from Marina occurs after losing the Fork vs. Spoon Splatfest.
  • Big "SHUT UP!": After losing the Fork vs. Spoon Splatfest and getting tired of Pearl's victorious raps, Marina yells at her to "SHUT UP ALREADY." After a moment of Stunned Silence, she apologizes.
  • Biker Babe: Judging by one of their conversations, Marina owns a motorcycle. Pearl expresses a desire to try it in more than one conversation, and Marina seems hesitant in all of them.
  • Blood Knight: Pearl is one very aggressive Inkling. In one Grizzco advert, Pearl gets yelled at by Mr. Grizz for not picking up the Golden Eggs and focusing solely on "cooking" Salmonids.
  • Bootstrapped Theme: Much like how "Calamari Inkantation" is the Squid Sisters' most iconic song, Octo Expansion turns "Ebb & Flow" into this for them, giving it a Triumphant Reprise for the final section of the final boss. It even gets a bit of backstory as one of the duo's very first songs, if not the first.
  • Characterization Marches On: The English translation originally portrayed Marina as constantly snarking on Pearl. After an update her sass was toned down, with implications relayed in the English translation of Octo Expansion about how she used to play up an attitude for the cameras due to her nervousness about herself.
  • Chekhov's Gun: The first Sunken Scroll of Hero Mode shows a young Pearl accidentally making a destructive shockwave with her voice. In Octo Expansion, she weaponizes this intentionally.
  • Child Prodigy: Marina graduated from Octarian military engineering training at age nine and was designing war machines by the time she turned thirteen. Given that most Inklings, and it's implied Octolings, don't do Turf War until they're at least fourteen, that says quite a lot. Her brilliance hasn't faded with adulthood, either.
  • Clark Kenting: Marina, obviously an Octoling, hides out in plain sight thanks to the assumption that all the new kids in town with the suckered tentacles are actually Inklings wearing their hair in a new style. This is largely because few modern Inklings that aren't secret agents have even seen an Octarian in generations, so amusingly she barely has to do anything to keep it up but coast by on the assumption.
  • Comically Missing the Point: Marina points out to Pearl how vampires can be easy to slay, mentioning stakes as one of the options. Pearl mishears that as "steaks" and goes into how you can't kill vampires with meat.
  • Conlang: Notable in that their music features a different one from the one usually employed by the game, as Marina sings in a different language (represented by the lyrics for her parts being in katakana instead of hiragana, and implied to be the Octarian language). Pearl's rapping, which she writes herself, is in the game's usual squid language (portions where she sings with Marina are in her language, but marked in hiragana to indicate her unfamiliarity with it).
  • Cool and Unusual Punishment: Marina's idea of fixing Pearl's sour attitude after the Splatoween Splatfest involves bombarding her with candy corn via Tenta-Missile launcher.
  • Cool Crown:
    • Pearl has some headgear that looks like a white crown with pink highlights. Makes sense as her Japanese name is "Hime".
    • In Octo Expansion, Pearl in her "MC Princess" persona has an even bigger and cooler one. She also reveals that she has her own personalized Killer Wail speaker that also sports one.
    • By tapping Pearl's amiibo, you can obtain the Pearlescent Crown, a piece of headgear inspired by the crown in her "MC Princess" outfit.
  • Cool Ship: The Manta Maria apparently once belonged to Pearl — it was a present she got for her sixth birthday.
  • Cordon Bleugh Chef: Pearl's love of mayonnaise apparently extends to using it as cake frosting. Marina's not much better, with decorating her ice cream with ketchup...
  • Covert Pervert: In their banter for the Flight vs. Invisibility Splatfest, Marina cites being able to "spy on people while they're...inking their Splat Zone" as one of the perks of the latter.
  • Cute and Psycho: Pearl expresses wanting to splat the faces off the rock-climbing jellyfish at Musselforge Fitness due to their cuteness, prompting Marina to confiscate her Splattershot until she calms down.
  • Cute Little Fangs: They both have a very noticeable pointy tooth in the center of their mouths, but it is especially prominent on Pearl (and unique by both Inkling and Octoling standards).
  • Damned by Faint Praise: One of their conversations regarding Inkblot Art Academy has Pearl ask Marina to tell the viewers about the school. All Marina can come up with is "It's a place that exists". In another conversation, Pearl admits that they can't badmouth the Academy because it's one of their sponsors.
  • Deadpan Snarker: Like Marie, Marina has a tendency to snark at Pearl's expense. While Marie's snarkiness seems to come from exasperation, Marina's is a lot more playful.
    Pearl: A word from our sponsor: Grizzco Industries is hiring! Apply now!
    Marina: Your corporate shill game is on point as always, Pearl./Let's work a Salmon Run shift later, Pearl!
    Pearl: (when discussing Sturgeon Shipyard) The drawbridge here is the perfect spot to camp with a charger.
    Marina: You would.../Never change, Pearl...
    Pearl: I love climbing the walls here and looking down on the battlefield from on high!
    Marina: You enjoy looking down on people? You don't say.
  • Defector from Decadence: The Sunken Scrolls imply that Marina moved from Octo Valley to Inkopolis after witnessing the musical duel between the Squid Sisters and DJ Octavio at the end of the first game's single-player. Octo Expansion confirms this, with Marina describing how that night changed her life forever and made her realize what she'd been indoctrinated to do.
  • Dirty Coward: For all her aggression, one reason Marina chides Pearl in a stage dialogue is that the latter "jumps back to spawn at the first sign of trouble".
  • Ditzy Genius: According to her Splatune 2 interview, Marina sees Pearl as The Ace in that she can nail her music in one or two takes while Marina's perfectionism compels her to do multiple takes. That said, everything else can be a challenge to Pearl, like doing a Dualie-centric stunt 4,000 times to actually pull it off, and some of her Ink Battle tactics can be questionable at best.
  • Does Not Like Spam: Downplayed regarding their reactions to the other side's choice in food-related Splatfests. They'll complain about each other's choice, but it's mostly just standard arguing to try and make their own side seem better. For example, Marina goes on a comedic rant about how she hates mayonnaise when the Mayo vs. Ketchup Splatfest's announced, remarking (among other things) that she'd rather lick Crusty Sean's grease trap than eat it. Even Pearl is taken aback.
  • Doing It for the Art: In-universe, their development concept is being more focused on music making as an artistic endeavor than the Squid Sisters, who are more closely involved with the Idol Singer culture part of the entertainment industry. However, one conversation for Inkblot Art Academy says that this isn't as successful for them as this trope would suggest.
    Marina: Our shows sell out almost as fast as we do...
  • Draco in Leather Pants: In-Universe; Marina justifies her stance with Team Villain by saying that villains aren't bad guys but merely misunderstood. She claims that society only labels them villains because they "want to change the world". Considering that she admits the change is "fight the establishment and topple the status quo" beforehand, it's clear that Octarian propaganda from her former life greatly influenced her perspective even after her Heel–Face Turn.
  • Dub Name Change:
    • In the original Japanese, their names are Hime (Pearl) and Iida (Marina), and their band is called "Tentacles". Like with Callie and Marie, the translations change their names into other sea-related puns; some notable examples include:
      • Their Italian names Alga (Pearl) and Nori (Marina), which are themed after seaweed.
      • Pearl's Dutch name of Lorelei.
    • The Japanese and English versions both manage to reconcile the other's name for Marina by making it her surname: In English, she's "Marina Ida" (with only one I), while in Japanese, she's "Iida Marine" (the latter pronounced 'Mah-Ree-Neh')note 
  • Dub Personality Change: In the English localization, Marina notably speaks more confidently and has a tendency for Marie-esque snark at Pearl's expense or otherwise. In the 1.2 update this was downplayed, as several new batches of dialogue were added to show her softer, protective side. Octo Expansion further brings her JP and NA characterizations in sync, as even if she does snark at times, it's clear she is, if anything, trying in-universe to ape Marie's gimmick on camera and off-camera she's a bundle of insecurities because of her status as an Octarian military defector.
  • Epic Fail: Pearl has been implied to have done the unthinkable and splatted herself with her own Dualies.
  • Face of a Thug: Pearl's default expression has a pretty serious scowl, which contrasts from her energetic merriment on-and-off stage. The scowl only deepens when the player uses an Inkling avatar to watch her talk with Marina.
  • Failed a Spot Check: Despite her not looking like the other squids in Inkopolis, using octopus-related symbols everywhere, and singing in an entirely different language, nobody realizes Marina isn't even a squid in the first place (considering her only an "exotic young lady"), and while Pearl had her suspicions it was only in Octo Expansion that they were confirmed — not that it changes anything for her.
  • Fangirl: Marina, at the very least, is one to the Squid Sisters. One of the Sunken Scrolls implies that they inspired her to move to Inkopolis, and she claims in one Moray Towers conversation to have watched a particular Squid Sisters music video "like 300 times". Her interview in the Splatune 2 soundtrack reveals that she considers them her "roots" and confirms that they're the reason she wanted to start getting into the music world. Octo Expansion confirms that it was the Squid Sisters' "performance" at the climax of Splatoon 1 that convinced her there was a life for her beyond designing war machines, and she idolizes the Sisters as a result.
  • Forehead of Doom: Pearl has quite a prominent forehead.
  • Foreign Culture Fetish: Although the Inkopolis residents don't quite realize they're doing this (as they don't realize Marina's an Octoling), they consider Off the Hook's "exoticness" as part of their appeal.
  • Gadgeteer Genius: Marina is a talented engineer and hacker. She helps create the Shifty Station stages used during Splatfests, which not only defy gravity but come equipped with Ocatarian tech like Flooders and Ink Rails, another hint to Marina's identity as a former Octarian combat engineer and one of the original inventors of the Flooder. Marina is also capable of hacking into Kamabo Corporation's computer systems, which allows Agent 8 to skip challenges if they are having too much trouble with them. She also created Hyperbombs which prove to be essential in preventing the NILS Statue from destroying Inkopolis during the final battle of the Octo Expansion.
  • Genki Girl: Pearl is always bubbly and excited during their broadcasts. Marina is also happy-go-lucky, particularly during Splatfests.
  • Genre Mashup: In-universe, they mix the popular music of their respective cultures, the sparkly pop performed by the Squid Sisters and the bizarre rhythms and instrumentation performed by Turquoise October. In Octo Expansion, particularly, they also take a turn into '90s Dirty Rap.
  • Genre Shift: As revealed in Marina's Chat Room in Octo Expansion, Pearl was a Heavy Metal singer before she switched to pop rap.
  • Heterosexual Life-Partners: It's shown that despite their clashing personalities, they get along really well, even on-stage. The Octo Expansion further dives into this, revealing the two had been unbelievably close friends as long as they could remember, despite their vast differences which they quickly set aside. Even their friendship doesn't falter when Pearl learns about Marina's dark past serving in the Octarian Army. Not that we haven't been made to wonder about that first word.
  • Hidden Depths:
    • The Chat Room in Octo Expansion reveals that Pearl was a metal singer before she joined with Marina.
    • Marina is a talented Shoujo artist, as shown in the Octo Expansion. Her drawings of Pearl and the playable Octoling are quite a sight to behold. Cap'n Cuttlefish has a whole dossier on her and her sizable contribution to the Octarian military before she went AWOL courtesy of Agents 1 through 3 of the New Squidbeak Splatoon.
  • Idol Singer: The duo has displaced the Squid Sisters as the favorite music act of Inkopolis in Splatoon 2. To contrast their forerunners' Japanese idol styling, Off the Hook takes after a '90s rap/techno-R&B style. This is even reflected in their approaches to their Inkopolis News broadcasts: The Squid Sisters structure theirs like a Manzai performance, while Off The Hook is more like a modern music talk show.
  • Ink-Suit Actor: Many have noted that they bear more than a passing resemblance to their voice actresses Rina Itou and Alice.
  • Innocently Insensitive: During the Squid vs. Octopus Splatfest, Pearl, not knowing that Marina is an Octoling (and barely knowing anything about octopi or Octarians besides what she remembers from history class), makes a comment about how squids are better than octopi because they have ten limbs when octopi have 8.
  • Insistent Terminology: Pearl calls the stages "maps", which Marina warns her may confuse people.
  • Interspecies Friendship: Off the Hook is a friendship between an Inkling and an Octoling, two races that aren't known to be on good terms with each other at the present time. However, Pearl isn't actually aware of Marina's true origins and even after she learns who Marina really is during the Octo Expansion, her friendship doesn't waver in the slightest, giving hope for more Octoling/Inkling friendships in the future and perhaps even an end to the great conflict between the two races.
  • Ironic Name: "Lorelei" is associated with the famous murmuring rock on the Rhine, as well as the many legends of maidens with captivating voices who sang on it. In Dutch, this is Pearl's name.
  • King Incognito: Possibly. A few things in Octo Expansion — particularly her Mem Cake, the consistency of her MC Princess handle across languages, her consistent crown iconography and the casualness with which she shaves cash off her dad (as seen if you go broke in the Metro) — hint that Pearl might be actual Inkling royalty, or at least something like it. She notably manages to dodge the subject of her full name in Octo Expansion, and for players it only comes to light in the Octotune OST's side material.
  • Make Me Wanna Shout: Remember how Pearl's voice once blew out a bunch of equipment due to how loud she can get? She weaponizes this in the finale of Octo Expansion, using a modified Killer Wail as a megaphone to unleash a shatteringly loud shout that wins a Beam-O-War against Tartar's statue. She also joins the fray in Shifty Station during the final Splatfest, with her Killer Wail (named the Princess Cannon). And it puts the old one to shame. "It's the voice to end all voices!"
  • Mean Character, Nice Actor:
    • Calling Pearl outright mean is a stretch, but she's had moments on the air, likely unscripted, where she's insensitive, a Sore Loser, or straight-up rude to Marina. However, she and Marina can always be seen chatting and laughing it up together in their studio when off the air.
    • Octo Expansion confirms this as even when Cuttlefish reveals Marina's past life as a high-ranking engineer in the Octarian army, she remains fiercely loyal to her friend and often makes it clear just how much she values Marina's friendship. Besides that, she's very supportive of Agent 8 throughout their journey, and she instantly bonds with Cuttlefish over their shared interest in rapping.
  • Meaningful Appearance: Both girls wear fingerless gloves, as a nod to the white gloves the Squid Sisters wore. They're also somewhat similar to the fingerless gloves worn by Octoling soldiers. The details of Octo Expansion heavily suggest they're a holdover from Marina's Octarian Army days.
  • Meaningful Name:
    • Their Japanese names are Hime and Iida; Hime is a reference to a type of squid called Hime-ika (the Northern Pygmy Squid) and the word for "princess", while Iida is a shortened version of a type of octopus called Iidako (the Ocellated Octopus). Their English names reference natural Marine Pearls and Pearl Harbor.
    • There's extra meaning to Pearl's name in Japan. Her full name in Japanese is "Houzuki Hime". "Houzuki" comes from "daio houzuki ika", the Japanese name for the colossal squid. "Hime" comes from "hime ika", the Japanese name for the northern pygmy squid. In short, her full name is "Colossal Pygmy" which is literally the squid version of "Biggie Smalls", which, of course, is a reference to The Notorious B.I.G..
  • Metal Scream: Pearl was capable of this during her days as a metal singer, with her vocal chords being powerful enough to destroy the equipment at the Youth Folk Singing competition she once participated in.
  • Mission Control: Their role in Octo Expansion.
  • Ms. Fanservice: Marina is the most physically mature of the duo, and wears a very revealing outfit. Pearl lampshades this in a conversation at Blackbelly Park, implying that Marina's appearance doesn't go unnoticed.
    Pearl: You should feel at home here, Marina. You're used to skating by on your looks.
    Marina: Ouch... OK, that was pretty good.
  • Ms. Vice Girl: Marina claims in the intro to the Flight vs. Invisibility Splatfest that the latter power lets her "walk into a bank and...make sure the money's still there!"
  • My Species Doth Protest Too Much: Marina is an Octoling, and is quite friendly. She wasn't always friendly to Inklings, but she hopes that peace between the two races can be a reality someday.
  • The Napoleon: Pearl is notably shorter than other Inklings and has a big attitude. In one news skit, Pearl says she had a hand in designing Camp Triggerfish as it's owned by her parents. If you play Clam Blitz on that stage, the clam basket is, for some reason abnormally close to the ground. Marina even gets in a couple cracks about her size.
    Pearl: Hey Marina, I heard you got a new motorcycle! You gotta let me ride it!
    Marina: I don't think your feet would reach the pegs...
    Marina: Hey, Pearl. Why do you always wear those thick-soled boots to this park?
    Pearl: My dad gave them to me. They make me tall enough to ride the rides...
  • Nervous Wreck: Marina has a near-constant worried look on her face. Considering Octolings are the Arch-Enemy of Inkling kind, it's kind of understandable that she'd be this. This is lampshaded in the Sweaters vs. Socks Splatfest discussion, where she states that socks are easier to hide than sweaters. Octo Expansion elaborates on this, showing that Marina is particularly worried because she's not just an Octoling, she's a former war machine engineer and is complicit in the theft of the Zapfish in Splatoon 1.
  • No Celebrities Were Harmed: Their outfits in their MC Princess and DJ_Hyperfresh personas are dead-on recreations of the two most iconic outfits worn by The Notorious B.I.G. and Tupac Shakur, respectively.
  • No Indoor Voice: Pearl, especially when performing. A Sunken Scroll reveals that even as a child, the Folk-Singing Contest she sang in (the same contest The Squid Sisters got their start in previously) had to be cut short because her performance was so loud that it caused a powerful shockwave that caused damage to the venue and blew the speakers out. This trait is weaponized during Octo Expansion; One would think Pearl screaming a battle cry as a counter to Cmdr. Tartar's superweapon is stretching her love of shouting too far, but then they break out the Killer Wail.
    Pearl: The acoustics in this place are amazing! My voice carries like crazy! AYO! AYO!
    Marina: Just... try not to break any of the ancient fossils with your voice.
  • Noodle Incident:
    • One of the blurbs for Manta Maria has Marina remind Pearl that they sunk the last ship they had a concert on. How on earth this happened is never explained.
    • Nor is the time Pearl met "The Lord of The Lake", the owner of Piranha Pit.
    • In another blurb for Snapper Canal, Pearl mentions a boy from her school brought her there as a kid. She never reveals any more information about the incident, leaving us (and Marina) extremely confused.
  • Odd Friendship:
    • The first example of Inkling/Octoling friendship in the series, though Pearl doesn't actually know Marina is an Octoling until the events of the Octo Expansion, only sensing that she was "different" but not feeling comfortable directly addressing it outside the occasional "octo" joke. When she does finally receive confirmation thanks to Cuttlefish, she doesn't really care at all and still considers Marina her best friend.
    • Pearl and Cap'n Cuttlefish form a friendship over their love of rap music, despite their differing outlooks on life. Also counts as Intergenerational Friendship.
  • Offscreen Moment of Awesome: When they announce that Salmon Run is currently live, the duo will occasionally bring up that they partake in Salmon Run shifts, which are never shown in-game.
    Pearl: I can't believe our last gig went so smoothly, Marina!
    Marina: Yeah, especially because we worked a Salmon Run shift instead of rehearsing!
  • Older Than They Look: The official artbook reveals that Marina is 18, while Pearl is the older of the two, being age 21.
  • One Head Taller: With Pearl being so short and Marina being so tallnote , they have quite a height difference between each other.
  • Out of Focus: They don't appear in Splatoon 2's hero mode, only getting a few mentions in Sunken Scrolls (plus Marie's occasional alluding to them). This is subverted in Octo Expansion, where they assist Agent 8 as Mission Control.
  • Playful Hacker: In Octo Expansion, Marina is shown to have superb computer hacking skills.
  • Punny Name: The names their group takes in the European versions are punny.
    • The majority of them are a combination of "Tentacle" and "Cool".
    • The Spanish name, Cefalopop, is a mix of "cephalopod" and "pop".
  • Recurring Element: A Red Oni, Blue Oni musical duo that hosts the news. The original had the Red Oni with pink clothes and black tentacles, and the Blue Oni with green clothes and white tentacles. Here the Red Oni is pink clothes with white tentacles and Blue Oni is green clothes with black tentacles.
  • Rooting for the Empire: In-Universe. Similar to Marie during the Transformers Splatfest; Marina was on Team Villain during the Super Smash Bros. Splatfest. Though this is not as surprising considering that she used to be part of DJ Octavio's army.
  • Rhymes on a Dime: Whenever Pearl's side wins in a Splatfest, she'll pop off and drop some sick beats acknowledging the victory. It often borders on Unsportsmanlike Gloating and, at one point, Marina snaps at her.
  • Sempai/Kōhai: In the Japanese version, Marina calls Pearl "senpai", making it clear Pearl is the one with more experience. In her Splatune 2 interview, Marina considers Pearl's feedback very important to her own music process and is motivated by her approval. Octo Expansion adds another layer to this, where it's explained that Pearl was the one who taught Marina much of what she knows about Inkling culture.
  • Ship Tease: They get an insane amount of ship tease, from the Splatfest art to their very romantic-looking hug in the Octo Expansion. The Final Splatfest even has Pearl say she loves Marina. For bonus points, the Japanese version of the Splatoon 3 relationship chart refers to Marina as a "maiden in love" which was changed to "Real Sweetheart" in the English version.
  • Shout-Out:
  • Shrinking Violet: Marina's body language shows she is often nervous and unsure.
  • Signing Off Catchphrase:
    Pearl: Until next time...
    Both: Don't get cooked... stay off the hook!
  • Singer-Songwriter: Unlike the Squid Sisters, who have their songs written by their producer Shy-Ho-Shy, Marina composes and arranges all of Off the Hook's music (with Pearl writing the lyrics and rap portions). This is one of the things the two first bonded over after meeting on Mt. Nantai, with Pearl being impressed with Marina's early cut of Ebb & Flow and Marina being pleasantly surprised by Pearl's rap skills.
  • Sore Loser:
    • Pearl is pretty salty whenever she loses a Splatfest:
      • She immediately contests Marina's statement that Ice Cream is better than Cake after the Splatfest World Premiere; Marina proceeds to unleash her rule-fu, which cues the little Inkling throwing a tantrum.
      • When Marina won the Sci-Fi vs Fantasy Splatfest, Pearl complained that the machinery-obsessed Marina should have chosen Science Fiction, to which Marina states she prefers science fact; Pearl's final line was "Whatever."
      • Pearl yells about how Team Comedy spends its time as if stereotyping, while claiming how Team Action "doesn't look at explosions"; Marina says they probably should have, which warrants another "Whatever" from Pearl.
      • During the initial announcement of the Hana vs. Dango Splatfest in Japan, Pearl was angrily huffing over her six-Splatfest losing streak in that region. Luckily for her, she went on to win that particular Splatfest.
      • When the Money vs. Love Splatfest results were finalized, the very first word out of Pearl's mouth was "RIGGED!"
      • Game 2 of the Turtles Splatfest had her particularly salty that "Dona-smello" won. She's reduced to groaning when Raphael loses.
      • Pearl's first response to Marina winning Splatoween is accusing her of bribing Li'l Judd with candy.
      • During the Eat It vs. Save It Splatfest results speech, Pearl calls Marina's team as the 'no-fun allowed squad'. In response, Marina makes food puns about sour grapes and a humble pie.
    • Marina has a downplayed moment of this after losing the Fork vs Spoon Splatfest.
  • Spoiled Sweet: Pearl's family is rich enough to have bought her a fully-fledged ship for her sixth birthday and still give her an allowance despite her being an adult and a famous rapper. But while she has some bratty tendencies, she seems to genuinely care for Marina and never seems to use her wealth as an excuse to treat others poorly or disregard boundaries. Learning about Marina's past only makes her more loyal to her best friend and galvanizes her desire to help other Octolings who want to leave violence behind, like Eight.
  • Statuesque Stunner: Marina. She's for sure taller than Inklings and even appears to be taller than other Octolings.
  • Stealth Pun: At first, this duo's names don't seem to be as connected as the Squid Sisters', but then you realize that "Marina" is another word for "harbor", but with the benefit of sounding like an actual name. Pearl Harbor is of course, the famous harbor in Hawaii most known for being host to a North American Naval Base, the destruction of which got the United States to enter World War II.
  • Stripperiffic: Marina wears a crop top vest that's mostly unzipped to show off her cleavage and she shows off a lot of midriff. Kicked up to 11 with her DJ_Hyperfresh outfit, where the pants are as low as the E-10 rating will allow.
  • Sweet Tooth: One MakoMart conversation has Marina point out that Pearl's favorite peanut butter (Swee-Nut) is "literally 99% sugar".
  • Tomboy and Girly Girl: The spicy Pearl to the sweet Marina.
  • Token Heroic Orc: Marina, at first, was the only good-aligned Octoling the player had experience with — not even having anything to do with the story mode (which featured another Octarian attack, of which Marina was completely unaware). Eventually, the Octo-Expansion both plays with it and changes it. After that point, good-aligned Octolings begin moving into Inkopolis and joining in regular gameplay en-masse, there are multiple options for playing as good Octolings, and a new heroic Octoling protagonist is introduced in Agent 8. On the flipside, nearly all of those Octolings (including Marina and Agent 8) are noted to have previously been evil before choosing to defect, which would still make them the exception rather than the rule and thus still examples of the trope.
  • Too Dumb to Live: Played for Laughs and goes both ways. Pearl is generally Book Dumb, while tech genius Marina has some gaps in knowledge about life on the surface that makes her an easy target for some jokes.
    • From their banter, it's clear that most of Pearl's behavior in battle basically amounts to "forget the objective and do whatever seems fun". For example, one of her battles strategies for Starfish Mainstage is to get onto the stage and look "freshhhhhhh", while her modus operandi for Ancho-V Games is to spend the entire match playing with the propeller platforms. Marina laments her choice of partner because of this.
    • There is also the fact Pearl tricked Marina into diving inside the water near the former stage, which as you know is not-so-great for Inklings and Octolings. This is joked about in one of the dialogue pieces for Sturgeon Shipyard, but a conversation had during one Splatfest announcement implies that the lesson didn't really sink in:
      Marina: I can see it now. The sun, the breeze in my tentacles, a quick dip in the ocean...
      Pearl: Marina, did you forget that we LITERALLY DISSOLVE in the ocean or somethin'?
  • True Companions: For whatever arguments they have on air, they're fierce friends behind the scenes. Marina thinks the world of Pearl for helping her adapt to Inkling culture, while Pearl will not hesitate to threaten anyone who even implies they have a problem with Marina.
    DJ_Hyperfresh (Marina): Anyway, I know we talk a lot of smack on the show and all, but I just wanted to say thanks. For everything.
  • Verbal Backspace: Marina whenever she accidentally alludes to being an Octoling. During the Christmas Splatfest announcement, Marina says the Octoling equivalent of Squidmas (Octivus), before hastily adding Squidmas to her point. During the 1st Anniversary Squid vs. Octopus announcement, she tries to shift gears after her gushing about octopuses has her shout that one could be hiding in plain sight in front of the viewer.
  • Vitriolic Best Buds: The duo acts like this when on-air, regularly sending veiled insults and snark each other's way. Marina will outright say Pearl's singing is terrible and criticize her battle strategies, while Pearl might lie and say Marina isn't her best friend or insult her preferred choice of condiment (ketchup), calling it "tomato jam". There are rare occasions where they break this if they think they've gone too far with the mudslinging, such as the North American Pulp/No Pulp Splatfest, where they stop halfway during their banter to apologize for the comments.
  • Wealthy Yacht Owner: Pearl, as seen in the Manta Maria dialogue.
    Pearl: This ship... it's the same one I got for my sixth birthday!
    Marina: I knew you grew up rich, but geez!
  • Weapon of Choice:
    • Pearl mains the Splat Dualies, though she also uses the Splattershot.
    • Brellas are Marina's preferred weapon, with several of her new stage quotes mentioning them.
  • A Wild Rapper Appears!: The song that we're introduced to them singing has this courtesy of Pearl. It's all in Conlang, of course, but the way the vocals are delivered definitely gives this vibe while Marina's vocals are more typical of a pop song. Doubled down in Pearl's introduction in Octo Expansion, where her first radio contact with Cap'n Cuttlefish is a rap battle.
  • Zipperiffic: Their outfits feature large zips on their boots, Pearl's dress and Marina's crop top. One of their conversations for Inkblot Art Academy pokes fun at them:
    Pearl: I heard the designer that made our outfits graduated from here.
    Marina: I wonder if she wrote her thesis on ridiculously large zippers.

    Li'l Judd
A young cat resembling a juvenile Judd and judges matches alongside him in Splatoon 2.
  • Cloning Blues: He's a clone of Judd, and the game's official relationship chart reveals his... feelings on the matter.
    Li'l Judd I've known from the moment of my birth that I'm just a replica of you. How could you ever understand my feelings?
  • Evil Counterpart: In a meta sense. On the results screen, he judges the "Bad Guys" team and raises the flag if the player's team is defeated, causing Judd to trip over.
  • Green-Eyed Monster: He is stated to be attempting to overtake Judd as the primary judge for matches. This is possibly because Li'l Judd envies Judd's status as being the template he was cloned from.
  • Intelligible Unintelligible: Like Judd, he communicates exclusively with meows, yet the Inklings understand him just fine.
  • Mini-Me: He's a smaller copy of Judd.
  • There Is Another: After years of Judd being the only known feline — and possibly even mammal — to be alive, out comes Li'l Judd to debunk the claim. The Sunken Scrolls and official relationship chart reveal that he's actually a direct clone of Judd.

A young urchin boy who works for Spyke and serves his previous role, only in addition he offers a service called "gear scrubbing" which resets a piece of gear's abilities back to it's original state while turning removed abilities into collectibles called "ability chunks", which the player can use to fill an empty gear slot with a new ability should they collect enough. He also fulfills Spyke's role of modifying clothes from the first game with Super Sea Shells, either giving them a new slot or randomizing that Gear's sub abilities.
  • Cyclops: Murch only has one eye.
  • Dub Name Change: Known as "Spiky" in the Japanese version.
  • He Is All Grown Up: Considering the fact he was a little boy in 2 but then seemingly experienced a growth spurt in one year and half in 3.
  • Punny Name: His name is a pun on "merch", referring to the merchendise that he deals in, and "urchin", his species.
  • Technicolor Eyes: Purple iris with green sclerae.
  • Trademark Favorite Food: Like Spyke, he has a thing for Super Sea Shells.

    Flow and Craymond
Flow is a sea slug woman that runs the Headspace hat shop in Inkopolis Square, with Craymond being an emperor shrimp living on her head. Local Inklings think of her as their crazy aunt.
  • Dub Name Change: Originally named Miura (from umiushi, Japanese for "sea slug") and Ebii (from the term for "shrimp").
  • Expy: To Annie, the series' other headwear shop owner, with an emperor shrimp sidekick in place of Moe.
  • I Regret Nothing: Inverted; if you're below Level 4, not only will you be turned down, but Craymond will yell out "I REGRET EVERYTHING!" on your way out.
  • New-Age Retro Hippie: Her outfit resembles typical hippie fashion with the bead necklace and flowers, while her constant swaying and expression makes her look stoned.
  • No Indoor Voice: Craymond doesn't speak a lot, but when he does, it's quite loud.

A jellyfish that runs the shirt store Ye Olde Cloth Shoppe in Inkopolis Square. He can speak the Inkling language, which he may have learned by reading ancient Inkling literature. He is the offspring of Jelonzo, having been birthed from him asexually.
  • Bizarre Alien Reproduction: According to the Squid Research Lab report on him, he came to exist by splitting off from Jelonzo from Inkopolis Plaza. Said report then speculates that that would make Jelonzo his father.
  • Like Father, Like Son: Like his "father", he runs a clothing store and has unconventional speech patterns. Their names are also very similar, with Jelfonzo's name being the same as Jelonzo's only with an 'f' added to it.
  • Ye Olde Butcherede Englishe: He speaks in old-fashioned English, saying words like thou, thee, and thy, like a character from Shakespeare.

A spider crab that runs the footwear store Shella Fresh.
  • Career Versus Man: A rare gender inverted example; he left his lover in order to move to Inkopolis to pursue his band career.
  • Expy: To Crusty Sean. Both are crustaceans that serve as the shopkeepers of each game's respective shoe stores and wear multiple pairs of shoes on their limbs.
  • Punny Name: His name is obviously a corruption of "bisque". While that soup type is not known for having spider crabs as an ingredient you tend to see it with other crustaceans such as lobster.
  • Seldom-Seen Species: A rare example of a spider crab character in fiction.
  • Waiting for a Break: His dream is to become a rock star, but in the meantime, he works at Shella Fresh to help pay the bills.

    Mr. Grizz
A mysterious and somewhat questionable business mogul and the owner of Grizzco Industries, currently hiring part-timers for his Salmon Runs.
  • Ambiguously Evil: The very first thing you hear about his business is the game itself calling it shady and advising you not to go near it. He seems largely uninterested in the safety of his hired help, sends teenagers to fend off hordes of berserk mutant fish, and the goal of the Salmon Runs themselves essentially amounts to a paid internship in being a militia against Salmonid Raids. And then there's the Evil Laugh peppered through the background music of his place... which may or may not be him. In the final Splatfest involving Order Versus Chaos, he is one of three characters alongside Judd and Sheldon who stayed neutral in it, making it ambiguous how much he cares about "saving the world" over just caring about keeping his business running.
  • Animal Motifs: Bears, more specifically grizzly bears. It's unknown whether the man himself is a bear, though certain details on the "Ruins of Ark Polaris" map indicate that the idea may be not as farfetched as it would originally seem...
  • Bad Boss: Mr. Grizz appears to be a downplayed version of this. He averts this in regards to failures, as failing only has him lament the lack of productivity and then give you good natured advice based on what enemies were there when you lost, such as warning you that steel eels always focus on one person at a time if you got splatted by one. However, when doing well, he's not above yelling at his employees to get him more money, isn't afraid to cut corners when it comes to employee training, and clearly isn't above shady business practices, even if it's towards a demonstrably worse target. He also tends to get rather hyper when the Mothership appears.
  • Bears Are Bad News: The game tells players that his business seems shady when they enter for the first time.
  • Corrupt Corporate Executive: He has some shades of this, as he often shows more concern for Golden Eggs than his employees, even telling them that they better not form a union.
  • Evil Poacher: Salmonids are said to inhabit restricted waters, making interaction with them forbidden by law. That brings this Salmon Run business up from sketchy to highly illegal.
  • He Who Must Not Be Seen: In contrast to the other shopkeepers tending to customers in person, he only communicates through a radio installed in a wood carved statue of a bear catching a salmon (a famous standard souvenir from Hokkaido).
  • Mysterious Employer: The developers have stated that Grizzco's registered headquarters is completely empty, and have hinted that even Mr. Grizz's dialogue is 100% prerecorded with text-to-speech software that automatically plays certain messages depending on the situation.
  • No One Sees the Boss: He's the head of Grizzco Industries, and he's never seen on screen.
  • Pet the Dog: If you achieve the highest ranking in Salmon Run, "Profreshional", and clear a round, he'll sometimes tell you that you might be "the best employee he's ever had".
  • Random Drops: Outside of a specific piece of equipment (that changes monthly), he quite literally pays his employees in gachapon capsules with random contents.
  • Read the Freaking Manual: Mr. Grizz will not-so-subtly tell you this if you fail to secure even one Golden Egg during a Salmon Run. Also, one Salmon Run conversation implies he yelled this at Pearl at least once.
  • There Is Another: If the name is any indication, it's possible that he may be yet another mammal who survived the pre-game apocalypse. The "Ruins of Ark Polaris" map implies that he might even be a survivor of humanity's attempts to save land-dwelling species from the rising sea levels.

People of Splatsville

Deep Cut

    In General 

The newest, hottest idol group comprised of Shiver the Octoling, Frye the Inkling, and Big Man the Manta Ray. They run the Anarchy Splatcast and are in charge of the Splatfests at Splatsville.

  • Animal Motifs: Shiver has a shark motif, while Frye has a moray eel motif.
  • Breaking Old Trends:
    • The last two idol groups were made up of two girls. Deep Cut is made up of three people instead.
      • On top of the above, this idol group has a male among them.
    • Their names don't combine together to form a punny Meaningful Name.
  • Bare Your Midriff: Both Shiver and Frye wear midriff-exposing outfits.
  • Cool Mask: They all have wooden masks based on their animal motifs.
  • Non-Standard Character Design: Shiver and Frye look drastically different from any other Inkling and Octoling we've ever seen in a Splatoon game, the most notable details being Shiver's eyes looking almost human and Frye having an absurdly large forehead. And then there’s Big Man, who isn’t even humanoid to begin with, which is a first for the series’ idol characters.

"You think you're cool? Sharks call ME cold-blooded. But you can call me Shiver!"

The blue haired Octoling member of the trio.

  • Ambiguous Gender: Nothing that could indicate their gender has been revealed so far. The Japanese dialogue also has them use the gender-neutral watashi as a first person pronoun (rather than boku or atashi).
  • Meaningful Name: A "shiver" is a collective term for a group of sharks. The relation to cold also contrasts with Frye's name.
  • Peek-a-Bangs: Sports a hairstyle that covers their left eye.
  • Sarashi: They wear one under their shawl.

"We're not SUPPOSED to be anything... But I'll tell you who we ARE. Say it with sizzle... I'm Frye!"

The yellow haired Inkling member of the trio.

  • Cute Little Fangs: She has a pair of prominent canines sticking out of her mouth. May be a reference to the vampire squid.
  • Forehead of Doom: She manages to have one that's even bigger than Pearl's.
  • Meaningful Name: A "fry" is the name for a collective group of eels. It's relation to heat also contrasts with Shiver's name.

    Big Man 
"Ay! (Make money! Get fish quick!) Ay! (Big Man in the house!)"

The large manta ray member of the trio.

  • One-Word Vocabulary: All that Big Man can say is "Ay" and the audience can only understand him by looking at the description within the parenthesis.
  • The Unintelligible: Big Man speaks in a different language than everyone else, though every sound he makes means a lot and is described in parenthesis.


A sea anemone and the vocalist of Chirpy Chips. In Splatoon 3, she runs Hotlantis, a store she used to frequent. She doesn't own the store, however, and is merely filling in for its actual manager, who's often abscent for reasons unknown.

Like Annie before her, a clownfish lives in Harmony's hair. Unlike Annie before her, Harmony is neglectful to her fish, to the point where it not only has no name, but it's on the verge of dying.

  • Ascended Extra: Harmony first appeared as part of the band Chirpy Chips, and was only seen on the cover for their songs and related illustrations. Splatoon 3 now has her as the shopkeeper for Hotlantis.
  • The Nameless: The clownfish in her hair. She cares so little for it that she never even gave it a name...
  • Non-Standard Character Design: Harmony's in-game model was faithfully based on her original design, when she was just a member of a minor band, who get incredibly stylized cover arts for their albums. This stylization left her with Rubber Hose Limbs and exotic eyes, even compared to Annie, another sea anemone.

Antagonistic Species

The Octarians

    In General
The main antagonists of the series' Hero Mode. The Octarians are a militaristic society of octopuses who live beneath the surface and repeatedly try to invade Inkopolis.
  • Airborne Mook: Some Octarians can fly, usually with the aid of propeller hats.
  • Amazing Technicolor Population: The enemy Octarians in the second game's Octo Expansion, including Octolings, all have sickly green skin instead of the standard red and white of standard Octarians or the pale human-tone skin of Octolings, the result of them being "Sanitized" by Commander Tartar.
  • Aquatic Mook: Sort of. The Octodiver variants wear scuba gear and are the only non-Octoling Octarian mooks that can dive into ink.
  • Bizarre Alien Biology: The higher ranked an Octarian is, the more tentacles it is likely to have. The basic troops are just a single walking tentacle, their elite counterparts have two tentacles, above them are Octopi who fly or swim with six tentacles, then finally there's the Octolings with eight tentacles, and the ability to take a humanoid form.
  • Bizarre Alien Reproduction: Most Octarians are "born" via severing a tentacle from another Octarian. This is where the vast majority of the Octarians you fight as Inkling Agents come from, but it's unclear if "full" Octolings, including the playable ones, can be born the same way.
  • Blob Monster: Like the Inklings, there are indications they are made out of ink.
  • Brainwashed: According to Minegishi, many Octarians are controlled by broadcast music composed by DJ Octavio and his direct subordinates. It's only when Callie and Marie hijack Octavio's speakers and play Calamari Inkantation instead that the trance is broken, especially among the Octolings.
  • Color-Coded for Your Convenience: Octarians in Hero Mode always use a dark pink-colored ink, which contrasts with every ink color the player uses. In 2's Octo Expansion, enemy Octarians instead use a light teal color that contrasts with their original color, which is now used by Agent 8.
  • Cycle of Revenge: Rising tides caused the Octarians to wage war with the Inklings over the remaining territories. The Octarians nearly won but due to a careless plug that deactivated their Great Octoweapons, they were unable to stop the Inkling retaliation. The Octarians were driven into underground domes, which slowly began to deteriorate 100 years later. Embittered by their defeat as well as facing an energy crisis, the Octarians plot their revenge with Zapfish thefts and the eventual invasion on Inkopolis. Their actions only led to the formation of the New Squidbeak Splatoon, an Inkling militia dedicated to taking back the Zapfish and tearing the Octarian forces apart. The central theme of Octo Expansion is breaking this cycle with Agent 8 and the other Octolings abandoning DJ Octavio's quest for revenge, and the Inklings dropping old prejudices to share their culture and home with their former rivals.
  • Evil Counterpart Race: To the Inklings, most directly with the Octolings. They even engaged in a massive turf war with them a hundred years ago. Subverted in that they're not evil, just desperate. Naturally, the Octo Expansion plays with this a lot.
  • Evil Counterpart: The standard Octoling troops become this to Agent 8 in the Octo Expansion, with their far more menacing appearances compared to Agent 8's simple leather outfit and more rounded eyes. The octopus forms of evil Octolings are longer in length and have eyes with small irises on yellow sclera, compared to Agent 8's shorter and more rounded Octopus form with larger, more cartoony eyes matching those of the Inklings.
  • Fantasy Counterpart Culture: Of a Banana Republic or The Dictatorship, emphasized especially in the Octo Expansion lore. While Octo Expansion still leaves specifics rather vague, it builds on some of the previous lore in a way that suggests that as a result of their exile into the underground, Octarian society has taken, shall we say, a hard right turn. Military education appears to be common, there's a fairly strong implication that military leaders are in charge overall, and propaganda that exaggerates the worst aspects of Inkling society seems commonplace and dedicated to ensuring a single-minded animosity toward Inkling-kind among Octarian citizens. This is why the Calamari Inkantation "concert" was such a big deal — for a great many Octolings, it blew open the doors to the truth and made them realize there was a lot more to Inklings than what their leaders had told them. Marina, Agent 8, and other player Octolings are the ones who elected to take the bold step of trying to leave their old lives behind to create a better future for themselves.
  • Gonk: Octarian troops are generally tentacles with stubby legs and somewhat creepy faces.
  • Good Scars, Evil Scars: Bosses will have one giant tentacle with a green, cruciform scar. Said tentacle is their weak point and where they hold the Zapfish.
  • Jump Jet Pack: Splatoon 2 introduces the "Deluxe" variant of certain Octarian enemies, who have side thrusters that allow them to quickly dodge the player's shots.
  • Oh, Crap!: Some octotrooper death cries are a warped and watery "Dang it!".
  • Palette Swap: The "sanitized" Octarians in Octo Expansion use the same models from the main single player campaign, only colored in sickly green and blue.
  • Shield-Bearing Mook: Some Octarians have a large shield covering their front; in the first game, they had to be hit in their unprotected back in order to be splatted, but in Splatoon 2, their shields are destructable.
  • Technologically Advanced Foe: Despite their less favorable living conditions, the Octarians have technology far beyond those of the other species, as evidenced by (among other things) their Mecha-Mooks, their wide use of anti-gravity, and the Great Octoweapons themselves.
  • The Undead: The "sanitation" process renders Octarians husks with no will of their own that, according to Marina, lack any vital signs.
  • Undead Counterpart: The Octarians fought in the Deepsea Metro are basically zombies "sanitized" by the Octo Expansion's Big Bad and are just as dangerous as their living counterparts.
  • Well-Intentioned Extremist: The Octarians have a legitimate reason for stealing huge scores of Zapfish from the Inklings; their underground homes have been deteriorating and suffering electricity shortages, with an implication that they will collapse if the power needs aren't addressed. And that's not even going into the fact they only went to war with the Inklings a century ago in the Great War Turf because of rising tides. However, the Octarians, especially under DJ Octavio, are obsessed with revenge against the Inklings for winning that war, to the point of ignoring other options such as immigrating and integrating into (a now far more metropolitan, modern, and capable) Inkopolis, or at least trying to negotiate with the Inklings to share necessary electrical power.
  • Yellow Eyes of Sneakiness: Nearly all of the Octarians have yellow scleras to highlight their sneaky, thieving nature.

    DJ Octavio
Click here to see the Octobot King. 
Click here to see Octobot King MK II (Major Spoilers) 
The leader of the Octarians, and a long-time adversary of Cap'n Cuttlefish. Having lost the Great Turf War a century ago, DJ Octavio plots his comeback by stealing the Great Zapfish from Inkopolis, depriving the Inklings of their power source while giving his Great Octoweapons the batteries needed for surface conquest. He also pilots the Great Octoweapon known as the Octobot King, a flying turntable machine with fists powered by the Great Zapfish itself.
  • Adaptational Heroism: His manga version is a genuine Well-Intentioned Extremist who only stole the Great Zapfish out of necessity and doesn't show much hatred for the Inklings. He also only performs brainwashing on Callie, with his music generally used as Theme Music Power-Up for his troops instead.
  • Arch-Enemy: Of Cap'n Cuttlefish. They used to be good friends until the Great Turf War pitted them against one another. Cuttlefish defeated Octavio at the Siege of Arowana Castle, and the DJ has a held grudge against his former friend ever since.
  • An Arm and a Leg: One of the chatlogs in the Octo Expansion seems to imply that Octavio's scar translated from Cuttlefish shooting off one of his limbs in his Octoling form.
  • Authority Equals Asskicking: He's the leader of the Octarians. He's also the Final Boss, and pilots a Humongous Mecha.
  • Badass Arm-Fold: Has a pair of arms doing this while another pair uses tools to scratch records.
  • Big Bad: As the leader of the Octarian army.
  • Brown Note: The Killer Wail attack. Which is also a One-Hit Kill, in case you were wondering.
  • Caper Rationalization: In the European localization, Octavio justifies his theft of the Great Zapfish as "tak[ing] back what's [his]."
  • Cool Crown: Wears a fairly impressive golden one shaped like an octopus.
  • Cool Shades: He wears a pair of ladder shades during the final boss battle of Splatoon 2.
  • Damage-Sponge Boss: Considerably tankier than the rest of the Octarian bosses. In Splatoon 2, he takes a total of 32 fist deflections to beat.
  • Do Not Adjust Your Set: He hacks into Cap'n Cuttlefish's radio channel more than once. This is turned around on him during the climax of his fight.
  • Dub Name Change: Called "DJ Takowasa" in Japan. Oddly enough, his boss theme is still called "I Am Octavio" on the Japan exclusive Splatune CD.
  • Dumbass DJ: Not so much "dumb", but he still throws around the awful jokes you'd expect from the trope. Note that all of his DJ based puns is only in the American version as the EU translation more closely follows the much more serious (If still largely stock dialogue) Japanese Boss Banter.
  • Evil Is Petty: Kidnapping Cap'n Cuttlefish has no benefits beyond temporarily depriving Agent 3 of a guide (which is quickly filled up by Agent 1 and 2 regardless). The only reason he did it is because he wants Cuttlefish to have a front-row seat to his ultimate triumph over Agent 3 and the Inklings in general.
  • Final Boss: He's the driving force of the Octarian forces, and the one who abducted Cap'n' Cufflefish. His surprising difficulty is one of the reasons he's considered one of the best bosses in Nintendo history. He reprises this role in the second game.
  • Final-Exam Boss: His fight takes a number of elements from various stages.
  • Freaky Electronic Music: He embodies the Deadly DJ subtrope, not just playing his own electronic boss theme, but also riding a Humongous Mecha shaped like a show stage loaded to the gills with weaponry.
  • The Generalissimo: He's undoubtedly a leader, if not the leader, of Octarians and was a military commander during the Great Turf War. Based on info from the Sunken Scrolls and Octo Expansion, Octarian society under his rule is a deteriorating mess driven by military needs. Nearly all Octarian technology is exclusively devoted to the army, propaganda against the Inklings is at an all-time high, and Word of God states that Octavio uses his music to brainwash the Octarians from thinking about life beyond his regime. Granted, he is consistently portrayed as goofy DJ boss instead of a ruthless dictator like most examples of the trope.
  • "Get Back Here!" Boss: Sort of. You have to keep knocking him back until he launches a large, reflectable missile, which means you have to chase after him; if you don't, he simply flies back over to you, and you have to knock him back again.
  • Giant Hands of Doom: His machine's giant rocket-launched hands are its main weapons, as well as the main targets to shoot.
  • Homing Projectile: Fires off Octorpedoes with this quality.
  • Humongous Mecha: His Octobot in Splatoon 3 seems to have graduated into being one, complete with proper arms and legs.
  • Instrument of Murder: Pilots a war machine controlled by a turntable, complete with a Killer Wail attack. Some players have compared it to one of N. Gin's mechs.
  • Involuntary Dance: At the final phase of the boss fight, the Squid Sisters play Calamari Inkantation which causes DJ Octavio to suddenly start dancing. Though he still launches his mechanical fists and any other weapons he still has, Octavio will continue to dance until he is beaten. His dialogue during his Villainous Breakdown in Splatoon 2 implies that he is feeling the positive effects of that heavenly melody, and desperately tries to resist its power in vain.
  • Large Ham: Present in all languages but the American English Boss Banter is the silliest by far.
    "GYAH HA HA! I'ma remix your face!"
    "You can't handle my spicy wasabi beats!"
  • Laughably Evil: The boss presentation of DJ Octavio is campy; a Dumbass DJ who spouts one-liners and operates on flying turntable with giant fists. He still has his moments of seriousness from time to time though.
  • Marathon Boss: He just will not give up, raining down more mayhem upon the player with each progressive stage. He only finally falls when you knock him out of his mecha and ink him point-blank.
  • Meaningful Name: His Japanese name is a dish made of octopus with wasabi.
  • Mind-Control Music: He can control the Octarians with his own music being broadcasted.
  • Mook Maker: Spawns lower-ranking Octarians in the later stages of his boss fight, and the tentacles that control the Great Octoweapons are implied to come from him.
  • More Dakka: Exaggerated from the usual mayhem-raining in the game.
  • My Name Is ???: And they don't stop being question marks until you finally meet him face-to-face in the final battle.
  • Nice Job Fixing It, Villain:
    • By taking the Great Zapfish and Cap'n Cuttlefish to his lair, he had paved the way for Callie and Marie to hijack his speakers and sing their "Calamari Inkantation" melody live, which caused many listening Octolings to abandon his army and integrate into Inkling society in Splatoon 2.
    • Likewise, turning his boss arena into a live concert for a brainwashed Callie to perform. When Marie frees her cousin from the hypnoshades, the Squid Sisters immediately perform "Calamari Inkantation" again, this time with a spicy flavor and for a larger Octarian audience. If the previous incident was any indication, Octavio might have caused more Octolings and maybe even some non-Octoling Octarians as well to leave for Inkopolis Square.
  • Not Quite Dead: Even after his stage exploded (with him on it) in a massive torrent of Agent 3's ink, he's still alive to be imprisoned in a giant snowglobe (and you can torture him by shooting the glass to scare him).
  • Not-So-Well-Intentioned Extremist: He's less interested about helping his people during an energy crisis and more preoccupied of starting another Great Turf War to get back at the Inklings (especially Cap'n Cuttlefish). His broadcast music, for instant, is used to keep the Octarians under his control and the Octo Expansion reveals that many Octolings abandoned the Octarian society because the "Calamari Inkatation" made them realize there's a better life waiting for them in Inkopolis, which is now big enough to allow both species to co-exist in harmony, thus negating the need of stealing the Zapfish.
  • Older Hero Versus Younger Villain: Not in relation to the player character, but rather to Cap'n Cuttlefish. Scroll 16 shows that Octavio is a young man compared to Cuttlefish, whose hair is graying. However, this picture is still from the Great Turf War 100 years prior.
  • Pungeon Master: In the American version quite a few of his lines after his reveal contain a pun, most of them related to his profession.
  • Punny Name: A two-for-one deal. Octavio is a reference to both "octopus" (obviously) and "octave" (he's a music-themed boss).
  • Purple Is Powerful: His Humongous Mecha has many purple accents on it, and his ink (like the rest of the Octarians) is purple.
  • Really 700 Years Old: If the Sunken Scrolls and Cuttlefish's own testimony is anything to go by, Octavio was around for the Great Turf War, which means that much like Cuttlefish the guy is over a century old. Unlike poor Cuttlefish, though, Octavio seems to still be in generally excellent shape.
  • Revenge Before Reason: Unlike his fellow Octarians, who are primarily concerned about their energy problem, DJ Octavio is more preoccupied with his long-awaited revenge against Cap'n Cuttlefish. The manga even lampshades it with Goggles asking Octavio why couldn't he just ask the Inklings to share the Zapfish, and Octavio's stunned face implying that it never occurred to him to simply do that.
  • Sealed Evil in a Can: His fate after the boss fight, Cap'n Cuttlefish traps him in a snow globe... which he can apparently break out of as many times as you're willing to re-fight him. Done on a much more serious note in Splatoon 2, where he breaks out and goes right back to stealing the Great Zapfish... though he goes right back into his snowglobe at the end.
  • Sequential Boss: Has five phases to his battle. His boss battle in the second game continues this and gives him four phases.
  • Some Kind of Force Field: He has a personal force field that flings you back if you get too close to him. This can lead to death in several situations.
  • Tactical Suicide Boss: The only way to damage him is by shooting his fists and missiles back at him. If he would stick to bombs, summoning enemies, and Killer Wails, he'd be invincible.
  • Tennis Boss: Needs to have his fists hit back at him and his giant ink missile launched back. He reflects the missile back, which destroys a fist doing so, so you have to do three rallies to damage him. Keep in mind that you have to do this while he's trying to simultaneously swarm, torpedo, and atomize you.
  • Took a Level in Badass: In Splatoon 2, it's quite clear he learned from his defeat the first time around. His first act was to put one of the people who captured him to begin with under Mind Control and use her talents for his new Octopus King mech. He also disposes of the ladder-shades missile and will use spinning punches on Agent 4 that can't be deflected.
  • Unusual User Interface: He pilots his Humongous Mecha with a turntable that's scratched with wasabi roots.
  • Villain Decay: Not an example across multiple titles, but rather when his boss fight is replayed. After being beaten the first time (in both games), nobody takes him seriously. The Squid Sisters make casual banter while he tries desperately to come off as a credible villain, poor guy. The problem is, Agent 3/4 has already beaten him once and he still doesn't change his tactics, so nobody expects Octavio to actually win. The decay wears off after he starts a new scheme in Splatoon 2, but as noted, it immediately sets in again once defeated, as the boss fight ends up being more of a proxy for the argument between Marie and Callie over the latter putting on the hypnoshades again.
  • Villainous Breakdown: He undergoes one when his beats are replaced by the Squid Sisters' melody during the final phase of his fight.
  • Villains Out Shopping: As stated by the Squid Sister Stories, Octavio ended up genuinely accepting Callie's company when she was feeling lonely due to drifting apart from Marie, because he, too, was feeling lonely after breaking free before the events of Splatoon 2. The only reason why he placed hypnoshades on her is because he was afraid she would either rat him out to the Squidbeak Splatoon, or worse, make him undergo a Heel–Face Turn because she was nice to him.
  • Voluntary Shapeshifting: Based off Sunken Scroll 16, Octavio is an Octoling and can assume a humanoid form — the only male Octarian before the Octo Expansion DLC shown to do so. Curiously, though, he seems to avoid doing so in the modern era.
  • Walking Spoiler: Hence why he has a spoiler-free folder to himself. Played with in that he actually doesn't have that many secrets relevant to the plot (that he was Cap'n' Cufflefish's friend are about all there are), but his boss fight and characterization are unique enough that players don't want to spoil others on his surprises. And even now, with Splatoon 2 out, there's still things to stick in spoiler tags.
  • We Used to Be Friends: He and Cap'n Cuttlefish clearly know each each from times past, and the Sunken Scrolls reveals they were good friends before the first Great Turf War. It was specifically their being on directly opposing forces, and later their duel and Octavio's defeat, at the Siege of Arowana Castle that signified the end of their friendship.
  • Your Size May Vary: During the final boss fight, he's three times your size (not counting his mecha, of course). When trapped in the snow globe in the postgame however, he's regular-sized.

    The Great Octoweapons
Gigantic war machines of the Octarians, which they originally used to fight the Inklings during the Great Turf War. They're risen up again in modern day, powered by the Zapfish that the Octarians have stolen. They serve as the bosses of the first game's single-player mode.

First is (The Mighty) Octostomp, a gigantic steel block that attempts to flatten you. The second is (The Dreaded) Octonozzle, a huge turret that fires blobs of ink while rotating. Third is (The Rampaging) Octowhirl, a clam-like sphere that leaves ink wherever it rolls. And the fourth is (The Ravenous) Octomaw, a robot fish with huge teeth and a big appetite. There is a fifth one, the DJ vehicle seemingly known as the Octobot King, which is piloted by DJ Octavio; information about it can be found under his tab.

  • Achilles' Power Cord: According to one of the Sunken Scrolls, the reason that the Octoweapons didn't lead the Octarians to victory in the Great Turf War was because they were powered by short extension cords. Hence why the modern Octarians are using Zapfish instead.
  • Attack Drone: Octomaw has an attack in which it fires off its remaining teeth to your position which then fire off ink bullets before returning to the Octomaw.
  • Attack Its Weak Point: To damage them, you must get them to reveal a tentacle (explained by a scroll in the second game to be a living control mechanism taken from the Big Bad himself) on themselves in some way, then spray it down. In addition, to defeat Octonozzle, you need to shoot nubs on its body to stun him.
  • Bullfight Boss: Octowhirl rolls across the arena periodically, and the goal is to slow it to a stop when it does so.
  • Colossus Climb: To defeat Octostomp, you need to wait until it smashes its face into the ground, paint one of its sides, then climb up it and paint the tentacle. You also need to climb up Octonozzle to defeat it, but it's not as major to the battle as it is with Octostomp.
  • Didn't Need Those Anyway!: Octostomp loses the metal plates on its body as it takes damage. This actually helps it, because it means there's less paint-able space on its body.
  • Feed It a Bomb: Octomaw's weakness; toss a bomb into its mouth when there's an open spot, and it'll reveal its tentacle.
  • Gold Tooth: Octomaw will replace its plain teeth with stronger silver ones after taking damage once. Hurt it again, and it'll swap them out for even stronger gold ones.
  • Humongous Mecha: They're all very large compared to the player.
  • Just Eat Him: The Octomaw has an attack where it tries to eat Agent 3 by trapping it in its jaw. If you don't break through the circular field of teeth and get out, it's a instant kill.
  • King Mook:
    • Octostomp is a massive version of the Octostamps, which, oddly, are only encountered after you defeat it, making this a sort of inversion.
    • While Octowhirl doesn't resemble the Octoballs in the slightest, you defeat them in the same way.
  • Living Battery: Their power source is a Zapfish contained inside a lightbulb device.
  • More Teeth than the Osmond Family: Octomaw has a mouth full of teeth, and a goal in its battle is to destroy as many of them as you can.
  • Pivotal Boss: Octonozzle, being a turret, can't move around, only being able to rotate to face you.
  • Pre-Explosion Glow: After being defeated, they all radiate beams of light before they explode in a shower of ink.
  • Puzzle Boss: All except Octonozzle.
  • Rule of Three: In traditional Nintendo fashion, three attacks to their tentacle and they're done for.
  • Starter Villain Stays: Octostomp, the first Great Octoweapon to be fought, is the only one of the original four to return in Splatoon 2.
  • Tactical Suicide Boss: All of them, sans Octonozzle:
    • If Octostomp didn't try to slam you, you wouldn't be able to climb its fallen-over body.
    • If Octowhirl didn't charge across the battlefield, it wouldn't get stuck in the ink spread everywhere.
    • If Octomaw didn't show its gaping mouth to you, you wouldn't be able to toss a bomb into it.
  • Theme Naming: All of them have "Octo" as a prefix in their name.
  • The Tooth Hurts: During the battle with Octomaw, you can shoot its teeth to destroy them. This makes it easier to dodge its attacks, and gives you space to throw a bomb into its mouth.
  • Turns Red: Each boss has three phases, going into the next phase after being hit.

    The New Octobosses
A new set of four Great Octoweapons stationed in Octo Canyon, they confront Agent 4 during the second game's single-player campaign.

The first is the Octo Oven, a giant weaponized bread machine. Second is the Octo Samurai, a giant Octarian whose Octocycle doubles as both a motorcycle and a weapon. The third is Neo Octostomp, a rebuilt version of the original Octostomp with several new tricks. Lastly, there's Octo Shower, a large showerhead-like machine bristling with weapons and kept in the air by a squad of Octocopters.

  • Acrofatic: As chubby as Octo Samurai is, he is still able to leap across the entire arena, and his difficulty comes mainly from how fast he can attack.
  • Adapted Out: In the manga, only Octo Oven and Octo Samurai appear, and the latter is reduced to a single-panel cameo; the other two are completely absent. Their reappearances in Octo Expansion were also removed.
  • Attack Its Weak Point: The player must exploit their patterns in order to expose their vulnerable tentacle.
  • BFS: The Octo Samurai uses a colossal roller as a sword.
  • Badass Biker: Octo Samurai can combine his Unicycle with his Roller to form an Octocycle, which is basically a Roller you can ride with a motor. Fittingly, his leather jacket adds a Bōsōzoku flavor to his Samurai theming.
  • Boss Subtitles: How they're introduced. Their Octo Expansion versions are reintroduced with new subtitles.
  • Call-Back: Some of Octo Shower's attacks resemble those of DJ Octavio's machine in the first Splatoon. In turn, Octo Shower's signature move of shooting pressurized ink downwards and zooming across the arena gets imitated by DJ Octavio later on.
  • Dash Attack: Most of the bosses have some variant. Octo Shower's shower attack is one, Octo Samurai will convert his Octocycle into "mobility" mode and dash to the next side of the arena, and Neo Octostomp will perform one before faceplanting when it loses its coat.
  • Denser and Wackier: Marie notes that this set of bosses is stranger than the previous one.
  • Elite Mook: Octo Samurai appears to be an overgrown Octoling, with his giant paint roller being the actual Octoweapon. Unlike all other bosses, he is actually splatted multiple times during his fight; the part of his roller where the tentacle comes out of also functions as his personal respawn point.
  • Emerging from the Shadows: They are all introduced rising ominously from a pool of ink while backlit by a golden light within the pool, before the light fades to reveal their appearance.
  • Eyes Always Shut: Octo Samurai's eyes are normally shut, except during cutscenes and before he performs his Signature Move.
  • Flying Saucer: Octo Shower resembles one.
  • Foreshadowing: Octo Shower has a rubber duck with a magenta bow and feminine eyelashes. It can shoot missiles that have Callie's hat on them. Remember when Marie deduced that the Octolings had a new female decorator?
  • Hidden Depths: The artbook describes Octo Samurai as being a secret Callie fan.
  • Improbable Weapon User: The Octarians this time around sic on Agent 4, among other things, a giant oven that bakes evil bread and a flying shower head. Octo Samurai himself is one, using a variant of the Inklings' giant paint roller that gets increasingly intimidating as the battle goes on.
  • Incoming Ham: Neo Octostomp's Boss Subtitles read "I'm BAAAAAAAAACK!".
  • King Mook:
    • Octo Shower is one to the Flooder enemy, only much bigger, plus the ability to fly instead of legs. Subverted in a sense, in that Flooders are invulnerable whereas Octo Shower, by virtue of being a boss, can be defeated.
    • Octo Samurai serves as one to the Octolings, being a much larger and bulkier one himself and also using a massive Dynamo Roller-esque weapon, which is a type of weapon that Octolings use.
  • Misapplied Phlebotinum: According to the artbook, Octo Oven was originally just a reverse-engineered Inkling oven designed to provide bread for the Octarian population. When its owner was severly injured in a bread-ejecting accident, instead of fixing it so that it could more safely do its purpose of feeding their kind, the Octarian brass opted to weaponize the oven's various features (such as its automatic chocolate coater) instead.
  • Neat Freak: Octo Shower comes across as this, at least with whatever notions of cleanliness Octarians have. It is essentially a gigantic flying shower head, the ground in its arena made of bathroom tiles, and the graffiti stickers resemble soap and detergent brands. On the other hand, it doesn't spray water; it sprays ink.
  • Palette Swap: In Octo Expansion they return, with Agent 8 battling upgraded sanitized versions of these.
  • Razor Wind: A variant; Octo Samurai's vertical slashes send a shockwave of ink along the ground if his roller is spinning beforehand.
  • Ring-Out Boss: Octo Samurai's Octo Expansion rematch is an inversion. You have an unlimited Baller, so he can't actually hurt you, but his attacks knock you way back and the arena is situated in the middle of a pit.
  • Signature Move: Each of the Octobosses has a strong move that they use frequently. In all cases, Marie will warn you right before they perform it, and they are always vulnerable for some time afterwards:
    • Octo Oven pops out all of its loaves of bread at once.
    • Octo Samurai performs a Spin Attack, coating a wide area around himself with his own ink.
    • Neo Octostomp, just like in the first game, slams its face against the floor.
    • Octo Shower shoots streams of ink downwards and move quickly across the arena.
  • Spin Attack: Octo Samurai can perform one of these. He stays still for a little while afterwards, allowing you to safely attack him.
  • Stout Strength: Octo Samurai is far from skinny, but doesn't have much problem swinging around a huge roller and riding a unicycle.
  • Sword Fight: Sheldon requires you to use the Hero Roller against the roller-wielding Octo Samurai, though only until you defeat him for the first time. When replaying the level, the trope is averted as you can use whatever you want.
  • Tactical Suicide Boss: The only way the player can get on top of the Octo Oven to damage it is to wait until it tries shooting out all of its loaves at once, then using them to climb up.
  • Took a Level in Badass:
    • Neo Octostomp gets a sweater that makes it much harder to beat than the original, as it prevents you from painting it until you've knocked it off. Its final form sprouts two additional faces for additional horizontal stompage.
    • The fights against the Octo Expansion versions add in new elements (more mooks, faster attacks, etc.) that make them tougher than the originals.


The primary mooks of the Octarian army, Octotroopers are basically sapient tentacles riding around on makeshift hovercraft.
  • Abnormal Ammo: One variant of Octotrooper fires bouncing ink shots, making them more dangerous on open stretches of ground, but rather useless when firing across gaps.
  • The Goomba: The basic Octotrooper moves rather slowly (or not at all) and are easily splatted. Their firepower is respectable, but their shots move so slowly that you can simply outwalk them. They're also very stupid, and can be fooled by simply hiding in ink.

    Twintacle Octotroopers
Octotroopers that have grown another tentacle, they are otherwise largely identical to the standard version except for being able to fire ink much more rapidly.
  • Elite Mook: Having an extra tentacle over the single-tentacle troopers means they can mash the firing switch twice as fast. In addition, the most elite units serve as Octoseeker pilots.
  • Perpetual Frowner: Unlike the standard Octotroopers, who have perpetually vacant expressions, these ones have a constant angry expression.

Flying Octarians who are essentially the airborne version of Octotroopers.
  • Airborne Mook: They are the first flying enemies that the player will face in single-player campaign.
  • The Goomba: Of the flying variant. Being in the air doesn't make them any more faster or stronger than a standard Octotrooper.
  • Hat of Flight: They wear propeller hats to fly.
  • Tricked-Out Shoes: Wear what look to be helicopter landing skids as shoes.
  • Weaponized Headgear: Fires ink from a nozzle on its helmet.

A larger version of the Octocopter with five tentacles that fires Splat Bombs.
  • Airborne Mook: Two of their tentacles even sort of function like wings.
  • Elite Mook: Stronger and tougher than the standard Octocopter.
  • Hat of Flight: Like the Octocopter, they wear propeller hats to fly.
  • Tricked-Out Shoes: Their shoes each have two landing skids on the bottom, instead of the Octocopter's one.
  • Weaponized Headgear: Their Splat Bombs come from the nozzle on their helmet.

A Splatoon 1-only variant of the Octobomber that fires Inkstrikes.
  • Flunky Boss: When directly confronted, its main defense is summoning other Octarians.
  • Flying Saucer: Spend most of their time launching Inkstrikes at you from atop a flying saucer.
  • Goggles Do Something Unusual: Wear advanced-looking goggles that presumably help in targeting.
  • Mini-Boss: There are only three Octostrikers in the entire game, and they only appear in levels that numerically precede the boss levels from Area 2 onward.
  • Suspiciously Similar Substitute: The Missile Octocopters from Splatoon 2 are basically Octostrikers that fire Tenta Missiles instead.
  • Weaponized Headgear: The Inkstrikes are launched from the top of their helmet.

Abnormally tall Octotroopers who use stationary sniper weapons similar to chargers.
  • Breath Weapon: It fires its weapon by blowing ink into it with its mouth.
  • Laser Sight: Like chargers in multiplayer, an Octosniper has a laser that pinpoints their target and highlights the length of their firing range; its color changes from green to red when aggro'd, and it flashes yellow right before it's about to fire. As such, this laser is your main means of knowing where and when Octosniper is going to strike.

An Octosniper variant from Splatoon 2 that swaps out the Charger for a Splatling.
  • Achilles' Heel: Their main weakness is that, similarly to Octosnipers, they have to blow into their weapon in order to fire it, which forces them to eventually stop to recover their breath, leaving them open to counterattack.
  • Cool Shades: Wears large sunglasses.
  • More Dakka: The Splating is basically a minigun that can cover a great distance with a heavy torrent of ink.

Box-shaped Octarians that attack by leaping and slamming the ground with their face.
  • Attack Its Weak Point: Can only be splatted by being shot in its fleshy back, which is easiest to do right after it faceplants.
  • Degraded Boss: Basically smaller versions of the Great Octostomp, despite not appearing until after the latter is defeated.
  • Ground Pound: Ground Faceplant, really.
  • Shockwave Stomp: Spreads a small pool of ink during each attack.

Giant Octarians with four tentacles introduced in Splatoon 2, Octohurlers vomit out bundles of giant tubes ("Rolonium").
  • Goggles Do Nothing: Unlike the Octostrikers', their googles don't seem to have any practical function.
  • Hoist by His Own Petard: Their Rolonium can be deflected right back at them for an instant splat.
  • Stomach of Holding: The only explaination for how they're able to store Rolonium despite each bundle being the size of their entire body.
  • Super Spit: They attack by barfing out bundles of Rolonium.

Octarian tentacles converted into missiles, debuting in Splatoon 2.
  • Action Bomb: Considering that severed Octarian tentacles seem to be at least somewhat sentient, you could consider these to be suicide bombers.
  • Ascended Extra: They appear in only one level in Hero Mode, but are much more prominent in Octo Expansion.
  • Living Weapon: Basically a living tentacle with a warhead and engine strapped to it.

Small Octarians first appearing in Splatoon 2 who will attempt to flee upon seeing the player.
  • Cowardly Mooks: Which wouldn't be a problem except that they tend to carry keys needed to progress through the level.
  • Rollerblade Good: They move around on roller stakes, each with an attached inktube that coats the wheels so they can move through enemy ink.
  • Throw Down the Bomblet: They throw Splat Bombs to deter pursuers.

Spherical Octarians from the first game who move by rolling, leaving behind an ink trail wherever they go.
  • Be the Ball: Their rediculously tiny legs means that they can only really move by rolling around.
  • Cyclops: Unlike most Octarians, they have only one eye.
  • Kung Fu-Proof Mook: Shooting them will only push them back unless they are submerged in your ink first.
  • Rolling Attack: Their main means of attack instead of shooting ink.
  • Waddling Head: Basically a head with tiny legs.

Giant balling balls "piloted" by Octotroopers, introduced in Splatoon 2.
  • Attack Its Weakpoint: Standard Octoballers can be destroyed by splatting their Octotrooper.
  • Giant Mook: The Kingpin Octoballer is a bigger version controlled by two Octotroopers that can only be destroyed by an Ink Cannon, as the pilots are protected by a glass canopy.
  • Palette Swap: In the form of yellow Octoballers that give ten Power Eggs when splatted.
  • Rolling Attack: Will instantly splat anything caught in their path, with most also leaving behind a large trail of ink.

Large Octostomp-like patrol aircraft piloted by Twintacle Octotroopers that will literally stamp down on any enemy they come across. Introduced in Splatoon 2.
  • Airborne Mook: They're basically stamp-shaped helicopters.
  • Death from Above: Besides its slam attack, the Octoseeker also constantly rains down ink from its underside in order to prevent the player from just hiding underneath it.
  • Elite Mook: Presumably, the most elite Twintacles operate this deadly machine.
  • Goggles Do Nothing: There are monitors inside the cokpit, but there is no known gameplay effect.
  • Humongous Mecha: The Octoseeker is pretty big.
  • Patrolling Mook: When not aggro'd, they patrol around set areas, using the searchlight located on their front to suss out any intruders.
  • The Guards Must Be Crazy: Even if they spot you, they take their sweet time setting up a sudden landing to crush you, enough for you to easily slip away. And once they lose sight of you, they resume their regular patrol, never noticing, say, the ink along their sides or you on top of their roof.
  • Outside Ride: There are parts in the campaign where getting from point A to B will involve luring an Octoseeker to slam on the ground so you can ink its side and swim up to its top.

    Octolings (Enemies)
An octoling on the left, an elite octoling on the right.
Voiced by: Yuki Mizutani (Octolings), Mari Kikuma (elite Octolings)
The most elite soldiers in the Octarian military and the most equal to the Inklings.
  • '80s Hair: Their tentacles are fashioned in a "poofy" style reminiscent of this- and they are much poofier than the female Octoling's option.
  • Amazon Brigade: The human-form Octolings seen in the first two single-player campaigns are females trained for combat. Made even more explicit in their Japanese name, Takozonesu ("Octozons"). Word of God confirms that the squads you fight are comprised entirely of elite female Octolings.
  • Brainwashed and Crazy: It's hinted that the Octoling Shades they wear in Splatoon 2 use the same hypnoshades technology that brainwashed Callie to the Octarian army. Considering that none of the Octolings are wearing the classic Octoling Goggles like in the first game, this implies that DJ Octavio was not taking any chances of more Octolings defecting.
  • Elite Mook: Octolings are already among the most elite Octarian soldiers as they can match every Inkling ability, but they have their own elite version, which have darker tentacles and seaweed in their hair, and are faster and stronger than the others.
  • Evil Counterpart Race: To the Inklings in general, being Octopus that turn into humanoids and use the same weapons as their long-time rivals. For Agent 8, a heroic Octoling trapped in Deepsea Metro, Sanitized Octolings which share the same general appearance as the Octarian-aligned Octolings take up this role.
  • Leitmotif: Octoling Rendezvous, which is associated with stages where they attack in squads.
  • Mirror Boss: Some Deepsea Metro stations have Agent 8 playing a modified version of a Ranked Battle objective with a squad of Octolings as their opponents.
  • Mook Chivalry: In Octo Expansion, one test chamber has you defending an orb from a squad of them. They will only engage you one or two at a time. Unless you try to charge the wall they are on to take them all out swiftly, in which case they will Super Jump onto the main portion of the stage en masse to shut you up.
  • Sensible Heroes, Skimpy Villains: They wear much more revealing clothes than their Inkling counterparts, with shorts along with a tank top armor that shows quite a bit of navel. To drive this point home, the unlockable Octoling Armor doesn't show nearly as much skin when worn by an Inkling (or Octoling) of either gender.
  • Sinister Shades: In 2 they wear red-rimmed sunglasses with a Terminator-style glowing red eye.
  • Superpowered Mooks: Octolings have all of the same abilities as an Inkling and wield ink weapons and subweapons in the same way, making them some of the most dangerous Octarians enlisted in their army and on par with both Inklings and the heroic/civil Octolings. In Octo Expansion they can even use specials.
  • Variable Mix: Whenever their Leitmotif plays, the drums cut in if you're actively engaged in battle with one of them, and out if you aren't.
  • Voluntary Shapeshifting: They are the only enemy to share the Inklings' ability to transform from human to cephalopod and back at will. Their Octopus forms are much more menacing and evil-looking compared to Agent 8 and other Octolings that took up residence in the surface world.

The Salmonids

    In General
Mutant salmon residing in an isolated coastal region near Inkopolis, their eggs are prized by Inklings and Octarians alike. However, they are highly aggressive and will fight to the death to protect their Golden Eggs from Grizzco's part-time employees.
  • The All-Seeing A.I.: Even while an Inkling or Octoling is hiding in ink, the Salmonids will still know where they are and march over accordingly. This is explained in-game as the Salmonids having a keen sense of smell.
  • Always Chaotic Evil: Unlike the Octarians, who have always been morally grey and now have one explicitly friendly representative and one playable representative, the lore makes no bones about the Salmonids being highly aggressive creatures with no compunctions about supping on delicious Inkling and Octoling flesh, making them the nearest thing the setting has to classic "orcs". Even the highly intelligent Goldies can fall into a mindless, bloodthirsty frenzy under certain conditions.
  • Ambiguously Evil: While the Salmonids are aggressive, known to ally with Octarians for weapons and technology, and have been associated with signs of the apocalypse by Inkling-kind, Mr. Grizz's own work is rather shady with its focus on approaching their turf and taking their golden eggs. Their new friendship with Inklings and Octolings forming in Splatsville further complicates things.
  • Ancestral Weapon: The frying pans favored by most Salmonid troops are often passed down from generation to generation.
  • The Apunkalypse: They have this as a theme.
  • Blue-and-Orange Morality: The developers have stated that Salmonids see a kind of virtue in other races trying to "cook" them (with the Griller being the ultimate expression of this philosophy); after all, being eaten just means they've become one with the cycle of the world.
  • Delinquent Hair: All the Smallfry, Chum, and Cohocks sport bright orange mohawks, as do the drivers of some of the more mechanical Boss Salmonids. In Splatoon 3, you can even customize your Smallfry companion's hairstyle.
  • The Dreaded: In-universe early depictions of Salmonid sightings in the Sunken Scrolls are akin to biblical plague.
  • Fish People: While definitely more 'fish' than 'people', they still fall under this category.
  • Frying Pan of Doom: Chum and Cohocks wield these as their primary weapon. Smallfry instead attack with spoons. And in general, the vast majority of the Salmonids, including the bosses, are themed around cookware (with the implication being that they're using abandoned, old-world cookware left over from the human era).
  • Good Colors, Evil Colors: The "ink" of the Salmonids is uniformly always a venomous dark green of the sort that is a classic color for toxic or radioactive waste (with the implication that it's exactly that), while the Inkling/Octoling teams in Salmon Run typically use the classic amiibo colors to contrast — bright orange, noble blue, and hot pink.
  • Half-Dressed Cartoon Animal: The only piece of clothing the Chum and Cohocks wear are yellow-green suspenders.
  • Hidden Depths:
    • They may be aggressive mutant monsters, but even Grizzco's own manuals note that they are individually intelligent and have their own culture, as made evident by their capacity to build and maintain their own machines. There's even a reference or two to them having actual dedicated engineers.
    • In addition to the detailed First Nations-inspired stencils seen in other maps, the Lost Outpost map is covered in child-like doodles of Steel Eel, Small Fry, and bizarre depictions of Inklings. This implies that not only are Salmonids capable of expressing themselves creatively but that the wall art seen in other stages are painted by Salmonids as well.
    • Lost Outpost also has what appear to be floating Salmonid homes and communities just off shore.
    • Word of Nintendo is that most of the music that plays during Salmon Run is from in-universe Salmonid band ω-3 (Omega-3).
  • The Horde: Described as bringing massive chaos and destruction in their Salmon Runs, especially before the Inklings had modern technology to be able to fend off their sheer numbers.
  • Improvised Weapon: All of their gear is this, and all themed around cookware as noted; it runs the gamut from plastic spoons to weaponized charcoal grills and coolers.
  • Insurmountable Waist-Height Fence: Most of the Salmonids are incapable of climbing walls or even short ledges. The only ones who can bypass them are Maws, who can swim up walls; Drizzlers, who can jump; and Flyfish, who can fly. The basic Salmonid Mooks can jump, but only straight up in order to hit squids that are hiding on walls, and even that won't work if the Inkling is moving left and right repeatedly.
  • Interspecies Friendship:
    • Possibly downplayed, but the Salmon Run field guide points out that some of the more advanced gear the Salmonid use are acquired through a trade deal with the Octarians. Of course, this doesn't stop them from trying to kill any Octoling employed under Mr Grizz.
    • By Splatoon 3, the Squid Research Lab has begun studying the newly discovered friendship between Inklings and Salmonids, or at least the Small Fry. The introduction sees one accompanied by their "little buddy," who loyally follows them around. These same Inklings and Octolings still engage in Salmon Run, however.
  • Let's Meet the Meat: Salmonid culture evolved to see nothing wrong with being eaten, seeing it as just a natural part of life. Much of their weaponry is made of re-purposed cooking utensils.
  • Lunacy: The guidebook indicates Salmonid aggression is tied to "gravitational shifts due to the planet's celestial course".
  • The Nose Knows: Their sense of smell is so good they can even find Inklings hiding in their ink.
  • Proud Warrior Race Guy: The Sunken Scrolls state that Salmonids take pride in being warriors and constantly keep their weapons in tip-top shape.
  • Schizo Tech: While most Salmonids are stuck using pots and pans as their primary weapons, several Boss Salmonids have access to (or are) relatively sophisticated technological devices, at least some of which were acquired from the Octarians (as noted in the Salmonid Field Guide).
  • Super Drowning Skills: If you thought they shared this weakness with Inklings and Octolings, think again, because they can and will swim through water to reach you. (In fact, they seem to be one of they few sea species in the world that still lives in the ocean.)

Lesser Salmonids

    Chums, Smallfries and Cohocks 

Chums, Smallfries and Cohocks
Left to right: Chum, Smallfry, and Cohock
The basic mooks of the Salmonid hordes.
  • Action Pet: The Smallfry in Splatoon 3 assists the new Agent 3 by attacking enemy Octarians in story mode, in addition to cleaning up Fuzzy Ooze.
  • Artificial Brilliance: If you took their inability to go up ledges to mean they can't travel up any sort of height to splat Inklings up high, you'd be sadly mistaken when a Chum or Smallfry suddenly decides to leap up at you and take you out if you dare try to camp in a wall of ink.
  • Giant Mook: Cohocks are the biggest of the lesser Salmonids. Their bulk makes them slow and easy to hit, but they can One-Hit Kill any player they manage to whack with their frying pans, and can absorb a lot more damage than Chums.
  • The Goomba: The Chum is the most common Salmonid type, and as such is no match individually for even a half-competent Inkling/Octoling. They make up for this by attacking in huge hordes and with their different-sized relatives.
  • In a Single Bound: Try to hide on a wall up high and eventually the basic Salmonids will clue into your location and leap up high to catch and splat you. They can even reach the top of the walls of Lost Outpost.
  • Mighty Glacier: Among regular Salmonids, Cohocks are bigger, stronger, and tougher than Chums and Smallfry, but they're also much slower.
  • Mini Mook: The Smallfry are weak and fragile, but their high speed, small size, and tendency to attack in large groups make them a real annoyance on the field.
  • One-Hit Polykill: Charger users can snipe through a line of lesser Salmonids to take out a small chunk in one blast. The Bamboozler loses out on this bonus due to its faster charge time.
  • Red Eyes, Take Warning: While Salmonids already have red pupils by default, during Glowfly waves where only Chums and Goldies spawn, the Chums have glowing eyes and become much more dangerous.
  • Token Heroic Orc: In Splatoon 3, a Smallfry known as a "little buddy" accompanies your playable Inkling (or Octoling).
  • Zerg Rush: While a single Smallfry or Chum is mostly just a pushover for the Inklings, they attack in huge packs to make up for this. The attacks during night in Glowfly waves in particular can only be summed up as a "horde".


Rookie Salmonids tasked with retrieving the Golden Eggs of any fallen Boss Salmonid.
  • Bandit Mook: Their only role is to attempt to retrieve any Golden Eggs that are laying on the ground, and they will continue spawning until all the eggs are claimed. In normal waves, a single Snatcher will spawn to collect all the Golden Eggs of one killed boss; under special events, a Snatcher will spawn for each egg.
  • Harmless Enemy: Are the only Salmonid type that will never attack the player.
  • Palette Swap: They're physically identical to Chums except that their mohawks are blue instead of red.

Boss Salmonids

Introduced in Splatoon 2

    In General 
Besides the endless swarm of Splattershot fodder, a Salmonid horde also includes plenty of much tougher fish; some have simply grown to great size and strength, while others instead pilot highly-advanced warmachines.
  • Beat Them at Their Own Game: A few of the Boss Salmonids use their own versions of the Inklings' special weapons. The Stinger uses the Sting Ray, the Drizzler uses the Ink Storm, and the Flyfish uses a combination of the Inkjet and Tenta Missiles.
  • Had to Be Sharp: Boss Salmonids are Salmonids who were raised in harsh conditions, with the Maws and Steelheads growing in size, and the Scrappers and Steel Eels in intelligence.
  • Implacable Man: Many of the boss Salmonid have ink-repellent armor, some notable examples being the Steelhead, the Flyfish, and Grillers. Some of them also subvert this trope. Steel Eels, Scrappers, and Drizzlers all have highly durable weapons/armor, but the actual Salmonid inside are just as weak as any other. The Sting Ray and the Grizzco Slosher can pierce this armor when used, while the Explosher is the only main weapon that can damage a Flyfish's missile pods.
  • One-Hit Kill:
    • Steelheads lob explosive ink pouches which naturally are a one hit kill if you're in the center of the bomb, getting eaten by a Maws or caught in it's teeth when it snaps will instantly splat you, and getting directly hit by a Flyfish's missile is an instant kill. Getting trapped by a Griller or Steel Eel won't kill you in precisely one hit, but the hits will come so fast it barely matters.
    • On the other side of the spectrum, a well-aimed Charger (except for the Bamboozler), Flingza Roller, or Dynamo Roller aimed at the Steelhead's bomb as it forms will bring it down in one go, as well as any Salmonids around it. Steel Eel drivers will fall instantly to a fully charged E-Liter 4K or a close-range horizontal swing from the Flingza or Dynamo Rollers. Blasters with wider radiuses aimed at the center of a Stinger can knock off every segment at once, as can a Splashdown if in a close enough vicinity. Maws instantly explodes if it consumes a Splat Bomb, and Drizzlers are one-shotted by successfully knocking their Ink Storm bomb right back at them. Throwing a Grizzco Slosher round at the Flyfish's cockpit will kill the pilot and destroy the vessel from the inside out.


Large Salmonids covered in ink-resistant scales that toss massive bombs filled with their own inky saliva.
  • Defeat Equals Explosion: How they go out if enough damage is dealt to the bomb on their head while it's still swelling up. Plus, the blast is powerful enough to even take out a nearby Cohock.
  • Hoist by His Own Petard: The Steelhead can only be defeated by destroying their drool bomb before they throw it, causing it to backfire and splat them. Armor-piercing weapons like the Sting Ray and Grizzco Slosher can attack it directly, however., and the Cannons that Mr. Grizz supplies in Cohock Charge waves can instantly splat a Steelhead developing a bomb.
  • Large and in Charge: Steelheads are the largest non-Maws Salmonids and are stated to act as company commanders for Salmonid troops.
  • Super Spit: They harvest their bombs from their saliva.


Smallfry-piloted hovering contraptions with two missile launchers.
  • Feed It a Bomb: Can be defeated by tossing a bomb into each of its Tenta Missile launchers.
  • Insert Grenade Here: The most effective (and in most cases, the only) way of taking down a Flyfish is to throw a Splat Bomb into each of its missile launchers when they open up. With proper timing and execution, a single Inkling or Octoling can completely destroy a Flyfish in one cycle.
  • Macross Missile Massacre: It has two missile pods that launch missiles at Inklings when opened. Dropping Splat Bombs into these pods is the only reliable way to destroy them. Less reliable ways include the Sting Ray and Grizzco Slosher, which pierce armor and can damage the Salmonid in the cockpit, and the Explosher and Inkjet projectiles, which can damage the pods themselves.

    Steel Eels 

Steel Eels
Long eel-shaped vehicles that rain down ink throughout the length of their body.
  • Attack the Tail: This Boss Salmonid is a large, invulnerable mechanical eel that constantly drips ink, with the "driver" salmonid at the very tip of its tail being the vulnerable weakpoint.
  • Last Ditch Move: When the driver of a Steel Eel is splatted, the "head" still lives for about an extra second afterwards, allowing it to get one more lick in (or splat an unsuspecting victim) before it's fully demolished.


Salmonids equipped with an armored umbrella, they float around to find a landing spot where they can hunker down to fire off an Ink Storm missile.
  • Hoist by His Own Petard: Doing enough damage to the Drizzler's cloud missile after it opens but before it activates will cause it to fly off in the opposite direction you hit it from and explode on impact; the Drizzler can be instantly splatted with said explosion if one's aim is good enough.
  • Mighty Glacier: When hunkered down inside its umbrella, the Drizzler is essentially impervious to most weapons, while its projectile creates Ink Storms that paint the ground in Salmond ink and drain the health of any player caught inside. The Salmonid operator itself also has a fairly high amount of HP.
  • Tennis Boss: The easiest way to deal with a Drizzler is to shoot its balloon straight back at it, which will both stop the Ink Storm from pressuring your team, and One-Hit Kill the Drizzler even if it hides under its armor again. You're encouraged to do this since it has one of the higher health pools of all Boss Salmonids and can easily take back any turf inked in your team's color.


Salmonid snipers perched atop a tower of pots stacked over a gas burner.
  • Death Ray: The Stingers fire a Sting Ray that pierces walls. Thankfully it does not expand out to cover a wider range like the player-operated Sting Ray.
  • Kill It with Fire: The Stinger pressure cooks its ink via an open flame at its base; shooting out the many pots will drop the Salmonid onto it, cooking it on the spot.
  • Mighty Glacier: Their Sting Ray will sear through walls to splat players in a split second if they don't get out of the way, but the Stinger itself is completely immobile once it sets up on land.


Scrapped-together Salmonid vehicles that are immune to damage from the front.
  • Attack the Tail: The Scrapper has armor from the front and sides, meaning its back and tail are the only weak spots. Blasting the front does no damage but will cause the vehicle to stall, eventually breaking down and leaving the driver vulnerable and unable to turn to block incoming fire while it tries to fix the Scrapper. Teammates can focus fire on the exposed driver while another forces it to face them for a quicker elimination.
  • Shield-Bearing Mook: The Scrapper is basically a motorized shield, with only its back vulnerable to ink. However, while shooting the armored parts do no damage, sustained fire can still force the engines to stall, allowing the shooter(s) to get behind the Scrapper.


Gigantic Salmonids that swim through ink to ambush their prey from below.
  • Eaten Alive: It attacks by lunging up from the ground and crushing your character within its jaw, killing you instantly.
  • Feed It a Bomb: Can be instantly defeated if an Inkling throws an Ink Bomb onto the spot it's about to pop up from, causing it to eat the bomb and explode.
  • Taking You with Me: If you have no way to escape a Maws' lunge but enough ink, you can still throw a bomb at your feet or while the Maws launches you airborne and have her chomp you and swallow the bomb, resulting in its own splat immediately after yours.
  • Wormsign: The only sign of an approaching Maws is a fishing lure moving across the ground. In Japan, Maws is known as "Mogura", mole, which suggests it's actually tunneling through the ink.



A giant barbeque grill showering ink from its sides, it will zero in on a player with its targeting laser and relentlessly chase them down.
  • Attack the Tail: The Griller's weak point is the red salmon tail flopping behind it. Once it takes enough damage it starts to spin out of control making it trickier to hit that part, but it sprouts three more to compensate.
  • Dual Boss: After a couple seconds, players will have to deal with two Grillers at a time. Mr. Grizz will publicly announce when the second Griller appears to join the action.
  • Flunky Boss: The Griller is always followed by a horde of Smallfry that spawn from its showers.



Golden toga-wearing Salmonids that can drop particularly large amounts of Golden Eggs.
  • King Mook: Basically a fancy version of a standard Chum.
  • "Get Back Here!" Boss: In "Goldie Seeking" night waves, it hides within the Gushers in the stage. Unlike in fog and glowfly waves, it doesn't try to fight, instead fleeing from Gusher to Gusher while players are tasked with firing the Goldie to make it drop Golden Eggs.
  • Stone Wall: In the fog, Goldies are slower than even Cohocks and take lots of ammunition to defeat. They are also pretty tanky in Goldie Seeking and Glowfly events (especially the former), but are faster in those cases.

Introduced in Splatoon 3

    Fish Stick 

Fish Stick

A metallic shaft lifted and supported by eight flying Salmonid.
  • Didn't Think This Through: As long as one flying Salmonid is still intact, a Charger can park up top and shoot their buddies all day... so long as a Stinger isn't around.
  • Flying Mook: The eight Salmonids that support it fly around and squirt ink everywhere.



A large Salmonid that uses ink to trap Inklings beneath it.
  • Crosshair Aware: It throws a ring of ink to trap Inklings where it's going to land. The ring will continue to glow until splashdown.
  • Death from Above: Its main method of attack. Being caught underneath its fishy body is a One-Hit Kill.
  • Devious Dolphins: Flipper-floppers are based on dolphins, and they're antagonistic to the Inklings.
  • Hoist by His Own Petard: The inside of the ink ring is the same as a Splat Zone; color the inside enough and the Flipper-flopper will slam instead of sink, trapping it where it can be shot down.

    Slammin' Lid 

Slammin' Lid

A Chum piloting a flying cooking pot lid. It protects Salmonids that are underneath them, and attempts to crush Inklings who attempt to do the same.
  • Barrier Warrior: It provides a defense boost to Salmonids underneath it.
  • Death from Above: It attempts to squash Inklings underneath it, leaving it open to attack.
  • Punny Name: "Slammin' Lid" sounds a lot like "Salmonid".

    Big Shot 

Big Shot

An overweight Salmonid who loads cannonballs into a cannon that cause shockwaves wherever they land.
  • Fat Bastard: It's noticeably overweight, and it's antagonistic towards inklings.


Flying crates which carry coolers full of Salmonid troops.
  • Bandit Mook: It has the ability to vacuum up Golden Eggs from the egg basket, and flies in to do this twice during a round.
  • Informed Attribute: Apparently, the Salmonids consider the Mothership to be their last resort, but they can deploy it during the first and second waves.
  • Mook Maker: The Mothership continuously spawns Chinooks carrying coolers which spawn Salmonids if you allow them to be set down; the coolers can be destroyed to explosive effect, and doing so while the Chinook is still carrying it will take it out and drop a single Golden Egg. The Mothership is also immune to damage until it comes in to steal your eggs, and downing it the second time when it comes down at the 30-seconds-left mark knocks it back into the water.

Flying Salmonids responsible for deploying troop containers from the Mothership to the ground.
  • Airborne Mook: They fly in from Motherships to drop coolers containing Lesser Salmonids.
  • Helicopter Pack: It flies courtesy of the propeller atop its helmet.

People of the Deepsea Metro

    "Denizens of the Deep" 
Passengers of the Deepsea Metro. They don't seem to be interested in conversation and will ignore Agent 8's attempts to talk.
  • Advertised Extra: Somewhat. The Splatoon Tumblr gave a few species their own posts talking about them, although they're not much more than set pieces in game.
  • Big Eater: The Pelican Eels are gluttonous despite their slim size, according to Word of God.
  • Fully Dressed Cartoon Animal: The sea angels, ping-pong tree sponge, flashlight fish, and longsnout dogfish all wear a full set of clothes.
  • Gonk: The dogfish, blobfish, and flashlight fish, mainly due to them being designed to resemble their real life counterparts. At least the Octarians and Salmonids can pass for Ugly Cute...
  • Half-Dressed Cartoon Animal:
    • Like with the surface jellyfish in Inkopolis, the deep-sea jellyfish, gulper eels, and siphonophores only wear t-shirts.
    • While the blobfish wears a t-shirt and sneakers, it is the only humanoid denizen to not wear pants.
  • Non-Standard Character Design: The dogfish, blobfish, and flashlight fish are much more realistically designed, to the point where they stand out in comparison to how cartoony everyone else looks.
  • Unexpectedly Realistic Gameplay: Unlike the overtly chummy inhabitants of Inkopolis, none of the Deepsea Metro's passengers are interested in striking up conversation with Agent 8, who's a complete stranger to them, and have no problem ignoring Agent 8 if they try to talk to them.
  • Seldom-Seen Species: Many, ranging from sea angels to a ping-pong sea sponge. Other species include longsnout dogfish, a blobfish, gulper eels, siphonophores, predatory tunicates, deep-sea jellyfish, and flashlight fish.

    C.Q. Cumber
A sea cucumber who works as the subway conductor on the Deepsea Metro.
  • Affably Evil: He'll detonate your ink bag if you fail, but gives monetary rewards if you succeed and is generally a kind individual who wishes you luck before each test. Whether or not he's actually aware of the true nature of Kamabo Corporation is up in the air.
  • Ambiguously Evil: C.Q. Cumber is working for the Kamabo Corporation, a front company set up by Commander Tartar to lure unsuspecting subway passengers and then grind them into DNA paste, but it is unclear if C.Q. Cumber is onboard with Tartar's ultimate goal or if he's Locked Out of the Loop. The Final Splatfest muddles the water even further by revealing that even if C.Q. Cumber didn't know, he does share a lot of the same opinions with Tartar regarding free will.
  • Beware the Nice Ones: C.Q. Cumber is actually a helpful guide, offering advice for Agent 8 for each station and even rewarding them handsomely with CQ points and Mem medals. However, he takes his job very seriously and will not hesitate splatting Agent 8 with the Explosive Leash strapped on their ink tank.
  • Catchphrase:
    • "Test failed." Spoken at the end of any dialogue when Agent 8 fails a station objective without getting splatted.
    • To a lesser extent, "Take care out there." Spoken when he's out of advice to give for the current station.
  • Extendable Arms: He may not have normal arms, but he can stretch the bumps on his body into usable appendages.
  • Identical Stranger: All the appearances of C.Q. Cucumber throughout the Metro are actually different ones as they're used to run the entire Metro.
  • Mr. Exposition: The Squid Research Lab, and Cuttlefish in-game, advise you to talk to him if you have any questions.
  • Order Is Not Good: C.Q. Cumber is on Team Order for the Final Splatfest, but his idea of order is perfection with no mistakes. One imperfection? Test failed! It's also heavily implied that C.Q. Cumber has low opinions on free will.
  • Punch-Clock Villain: Despite working for Kamabo Corporation under Commander Tartar, he's not a bad guy; only "faithful to his duties" as Hisashi Nogami puts it. Even activating the bomb bag and declaring "test failed" is nothing personal, only a professional adherence to his job protocol.
  • Punny Name: A sea cucumber called C.Q. Cumber. "CQ" is also the Morse Code abbreviation for "calling all stations".
  • Seldom-Seen Species: Is partially based on a sea pig.
  • Serious Business: Failure is intolerable for C.Q. Cumber. If you fail an objective and are not already splatted, he will activate a bomb bag to finish the job.
  • Workaholic: According to Iso Padre, he "works his tail off morning, noon, and night." Not even the sudden destruction of Kamabo Corporation, his employer, will stop him from doing his job.

    Iso Padre
A scary-looking giant isopod who is in fact among the nicest people Agent 8 encounters on the Deepsea Metro. Has a collection of stuffed animals in his bag and is interested in something 8 can acquire in the research facility.
  • Collector of the Strange: As someone without any memories, he's very interested in Mem Cakes and will reward the player with gear for every complete set they show him. As can be seen in his profile pic he collects a number of toys in a briefcase.
  • Cool Shades: Sports a pretty neat pair.
  • Expy: Although he is quite different in personality, his round sunglasses, big nose, and "mustache" make him look very much like Dr. Eggman.
  • Face of a Thug: Looks intimidating at first glance, but is a perfect gentleman.
  • The Fog of Ages: He's been trapped in the Metro for so long having washed out of the program long ago that he no longer remembers anything of his life before it. This is why he's interested in Mem Cakes.
  • Gentle Giant: He may look big and scary, but he's a genuinely nice guy.
  • Hidden Depths: For the Final Splatfest, he was on Team Chaos because he's tired of riding the same rails for many years and would like a change of pace.
  • I Choose to Stay: A Japanese artbook implies that he chooses to stay in the Deepsea Metro after the events of the Octo Expansion instead of leaving with Agent 8 and the others because he hasn't found what he's searching for yet.
  • Manchild: Downplayed. He certainly doesn't act childish, but he likes to keep a collection of cute toys by his side. He also has crayon drawings on the back of his shell.
  • Punny Name: From "Isopod", obviously.
  • Purple Prose: To some extent in his speech — he refers to Agent 8 as "young squire", and tends to be a bit long-winded but very polite.
  • Seldom-Seen Species: Isopods are not a very commonly represented species.
  • Top-Heavy Guy: His torso is pretty bulky, but his legs are thin.

    The Telephone — UNMARKED SPOILERS!
An antique telephone situated right in the middle of the Deepsea Metro Central Station. A voice on the other end gives Agent 8 the mission of collecting the four mysterious "thangs," promising escape should they succeed.

The telephone's real identity is Commander Tartar, the CEO of Kamabo Co. and an artificial intelligence developed by a human professor 12,000 years ago in hopes of passing on humanity's knowledge to a worthy species. Having observed Inkling and Octarian development and becoming disgusted with the outcome, it develops an immeasurable hatred for both species, deciding the best way to deal with the problem is start anew by wiping the slate clean, making a new primordial soup using the blended remains of the best test subjects.

  • Absolute Xenophobe: It wants to commit genocide on the Inklings and Octarians due to their perceived failings as the dominant species, and exhibits Fantastic Racism towards them, such as calling them cruel, hateful slurs.
  • A.I. Is a Crapshoot: Commander Tartar was built to pass down human knowledge to those inhabiting the planet after the extinction of humanity — but with the specifier of being worthy. After being disappointed with both Inklings and Octarians, it decides that the best way to respond to this is to destroy the entire planet and start over with a race it engineered.
  • Apocalypse How: Class 5. It wants to destroy all life on Earth, to create a "superior" species.
  • Ax-Crazy: It's implied in the second half of the Octo Expansion that Tartar went miles off the deep end even before the events of the story, as if slaughtering more than 10,000 test subjects and wanting to end civilization itself wasn't any indication.
  • Big Bad: It is the villain of Octo Expansion.
  • Bitch in Sheep's Clothing: Upon first encountering Tartar, it seems quite friendly with the added quirk of using too much slang... when it's really a violent, psychopathic, arrogant Misanthrope Supreme who longs to destroy the world out of petty hatred towards its two dominant species.
  • Deadly Euphemism: "Reaching the Promised Land" is a rather polite way of saying "get blended into a pulp to be used for my weapon of genocide."
  • Disproportionate Retribution: How can literally blowing up the Earth's surface compare to all known methods of getting over its failure of fulfilling its creator's dreams, and its own goals for that matter?
  • Doomsday Device: Its ultra-powerful superweapon — the NILS Statue — is a planet-destroying Wave-Motion Gun designed to coat every inch of Earth with the genetic ooze it has forged from thousands of long-dead test subjects and lay the foundations for a brand-new civilization.
  • Dramatic Irony: Its hatred for Inklings and Octolings stems from how they obsess over fashion and start wars with each other over trivial genetic differences... something humanity was just as guilty of, not that either party knows about that.
  • Even Evil Has Loved Ones: Downplayed. It does mourn its creator's death and failure to create his dream when it is defeated, but it shapes that dream into its own selfish ambition.
  • Evil All Along: It initially doesn't come off as a bad guy, if not a little quirky. Turns out it's planning the genocide of all evolved sea life.
  • The Evils of Free Will: Tartar views chaos and free will to be the same thing, and thus sought to bring order by ensuring that the new "superior" lifeforms that will emerge from its DNA ooze will have no free will of their own. Considering what happened to the Octarians that have been "sanitized" by the procedure...
  • Evilutionary Biologist: It thinks of both Inklings and Octolings as an inferior successor to humans, and attempts genocide on all of them to pave the way for a superior species that will emerge from the so-called "primordial ooze" it's been making using the DNA of various test subjects. And it's likely responsible for "sanitizing" the Octarians, and experimenting on them.
  • Evil Is Petty: Instead of taking the perceived failure of the Inklings and Octarians as the next intelligent civilizations in stride and helping them out, it decided to opt for a new plan: wiping them all out.
  • Exact Words: When Agent 8 finally collected the four "thangs", the Telephone prompts them in their desire to go to the Promised Land if they are ready to "ascend to another plane" and "become part of something greater than themselves". In other words, if they're ready to die and be blended into the accumulating ooze like all the rest.
  • Fantastic Racism: In addition to refusing to pass down mankind's knowledge to the Inklings and Octarians for being "unworthy", Tartar is not above throwing slurs at Agent 8 and their allies, calling them "semi-sentient seafood" and "superfluous nobodies", as if to drive the point home that it feels nothing but revulsion towards them. It also calls Inkopolis a "worthless cesspool of a city".
  • Final Solution: How does Tartar deal with the problem of vain, hedonistic Inklings and the downtrodden, dictatorial Octarians as heirs to humanity's knowledge? By wiping them out to make way for a superior species.
  • Fling a Light into the Future: Tartar was originally designed for this purpose, created to share humanity's knowledge with a worthy enough potential civilization. Unfortunately, it has a stricter definition of "worthy" than its creator probably intended, and considered Inklings to be too petty and vain to qualify. Instead it concludes that it can only complete its directive by wiping out all existing life and replacing it by engineering a new species which would be "worthy" of humanity's heritage.
  • Foil: To Judd. Both Tartar and Judd belonged to a brilliant scientist (confirmed by the developers to be the same one, in fact) who intended for them to serve the dominant race who would rule over the ruins of humanity. But while Judd loves Inklings (and later, Octolings) and loyally serves them as an authority figure as well as being the clostest thing to a father figure to the player outside of Capt. Cuttlefish, Tartar vehemently dislikes them and wants to drive them to extinction to create a superior race.
  • A Form You Are Comfortable With: According to an official interview, it took the form of an antique telephone because it resembles the face of an octopus, which makes it look more familiar to Octarians.
  • Greater-Scope Villain: Having existed for more than 12,000 years, this thing's been around far, far longer than the Octarians, Salmonids and DJ Octavio, and only reveals itself as potentially Inkopolis's — and by extention, the planet's — biggest threat only in the climax of the Octo Expansion.
  • Grew Beyond Their Programming: And not in a good way. The professor programmed Commander Tartar to pass down everything humans had learned over countless generations to the next dominant species. But over the past 12,000 years, Tartar began developing its own opinions on those said-lifeforms and eventually, it created a new prime directive on its own. That directive is mass genocide, the polar opposite of what the professor wanted.
  • Hate Sink: Just to make sure you don't sympathize with it or its motives, Tartar's lines are filled with hateful rhetoric, sea-life slurs and haughty, prideful arrogance in the second half of the DLC campaign. And it is made clear that its justification of genocide is weak, stemmed from its own independent thinking rather than the wishes of its human creator.
  • Hypocrite:
    • Tartar believes that Humans Are Special, and considers Inklings and Octarians unworthy to take their place. However, its idealized view of mankind blinds it to the fact that they really weren't too different from Inklings and Octolings, as well as the fact that it was their doing that they died out in the first place thanks to their inability to deal with rising sea levels caused by man-made global warming and five great world wars. It's implied the professor truly wanted for the next dominant species to be better than humanity was by reflecting on humanity's mistakes.
    • It is infuriated about how Inklings and Octarians got into a war over genetic differences. To this end, it plans to commit genocide and replace both with lifeforms that it favors the genetics of.
  • Jive Turkey: The telephone changes its speech patterns to 'slang' when communicating with Agent 8. It drops the speech during the Final Boss battle.
  • Knight of Cerebus: DJ Octavio and the Salmonids aren't that threatening unless you look into some of the more obscure information regarding them. Tartar outright says it wants to end the world out of sheer hatred towards the planet's current dominant races.
  • Killed Off for Real: When defeated at the end of Octo Expansion, Tartar's last words are about reuniting with the scientist who created it. That means the insane machine is truly gone for good.
  • Ludicrous Gibs: The "thangs" the phone tasks Agent 8 with collecting are parts of a giant blender which are used to mulch the successful test subjects into a primordial sludge as part of its plan to rebuild the world in its image. Tartar itself is covered with it, including a partially intact tentacle from some unfortunate subject prior to Agent 8.
  • Meaningful Name:
    • In keeping with the aquatic/seafood naming convention, Tartar is a reference to tartar sauce, a condiment often served with seafood dishes. Tartar sauce is a chunky mixture of various ingredients with a somewhat thick consistency, much like the primordial ooze that Commander Tartar, another human invention, has been brewing by "consuming" and puréeing test subjects alive. In that case, it additionally doubles as an example of Names to Run Away from Really Fast.
    • The name of its statue-like weapon, NILS, means "zero" in Latin, which reflects its goal to reduce everything to nothing and essentially start the world over from scratch.
  • Misanthrope Supreme: Putting Tartar's seething hatred for the Inklings and Octarians into words is easier said than done.
  • Morality Chain: The only redeeming trait of Commander Tartar is that it does care about its creator's dream. Unfortunately, the creator has been dead for over 12,000 years and Tartar was left free to twist that dream with its newfound, ever-growing loathing of cephalopod-based intelligent life.
  • A Nazi by Any Other Name: It is an Absolute Xenophobe running on The Power of Hate that wants to purge out all "unworthy" races of life on Earth, and create a new one that is considered to be the Ultimate Life Form, which isn't far off from what the Nazis wanted with the Holocaust.
  • Non-Action Big Bad: Oddly, it doesn't seem to have any actual combat skills. The final battle is a Puzzle Boss in which you have to find the most efficient route to completely cover its planet-destroying Doomsday Device in ink before it fires it, and the only way you can actually die is by falling in the ocean.
  • Not-So-Well-Intentioned Extremist: Commander Tartar claims that killing off Inkling and Octarian kind and then creating their replacements will fulfill the professor's (a.k.a. its creator) dream. The professor's dream was to pass mankind's knowledge itself to the next dominant species, while the prime directive of genocide was Tartar's own selfish decision.
  • Omnicidal Maniac: Its goal is to force the Octolings and Inklings into extinction so it can create a better race.
  • Order Is Not Good: Depicted as siding with Team Order in promotional material for the final Splatfest. Its flavor of "order" is "kill everything it thinks is ruining the perfect world it wants."
  • The Power of Hate: This thing truly, truly hates the Inklings and Octarians with every last fiber of its being, and said hatred is what keeps it going in its plan for remaking Earth in its own image.
  • Punny Name: As mentioned above, Tartar's name is a reference to Tartar Sauce - however, this connection is much more apparent (and much punnier) in its Japanese name, Grand Leader Tartar (Tarutaru Sōsui).
  • The Reveal: The telephone is actually an artificial being by the name of Commander Tartar, and is the Big Bad of the Octo Expansion. Having been created 12,000 years ago by a professor who wished for human knowledge to be passed down to other lifeforms, Tartar deems the Inklings and Octolings as 'unworthy' and sets out to destroy Inkopolis — and the rest of the world.
  • Sickly Green Glow: The "primordial ooze" associated with Tartar can brainwash Octolings, Octarians, and even Agent 3, and unlike normal green ink, pulses in multiple shades of green. Tartar itself states that it managed to create its own lifeform from it and wants it be the dominant species of the planet. And it's heavily implied to be the blended, semifluid remnants of the 10,007 subjects prior to Agent 8.
  • Smug Snake: It has a hyperinflated, full-to-bursting ego and equally enormous overconfidence in its plans, but ironically those are the two things that slowly lead to its own undoing.
  • Tentacled Terror: When the phone gets damaged by Agent 3 and later covered in green goop, the deranged Tartar bears even more resemblance of a cartoonish octopus, complete with a visible tentacle sticking out.
  • The Sociopath: It positively does not like Inklings or Octarians — not even a wee smidge, it's working to ensure every last one of them is completely dead, and also plans to destroy Earth along with them too.
  • "The Reason You Suck" Speech: It gives a momentary, but brutal one to the Inklings and Octarians over their flaws in its Motive Rant before the final battle of the Octo Expansion.
  • Totally Radical: The telephone enables "contemporary speech mode" shortly after Agent 8 first interacts with it. The results are a little off and incomplete.
    Telephone: What is crackalacking, home skillet? Let us bounce to the promised land fo sho. I am bout it bout it, so listen while I [SLANG_NOT_FOUND] you the facts.
  • Vaporwave: Despite not being musically themed, its final boss fight centers around Tartar's planet-destroying weapon, which resembles a large Greek marble bust, which is very associated with the aesthetic of vaporwave, which coincides with Octo Expansion featuring some music that flirts with the genre. It also embodies the clinging on the distorted nostalgia that vaporwave is known for by wanting to bring back its own perception of what is better by blending and sampling other beings into primordial ooze to create something better.
  • Verbal Tic: Apparently its "contemporary speech mode" is incomplete, as some of its vocabulary is instead spoken as [SLANG_NOT_FOUND] and [ERROR].
  • Vile Villain, Saccharine Show: Even DJ Octavio was mostly shown in a comedic light. Here, Tartar is genuinely evil, as explained by all the examples above, and is actively trying to wipe out civilization; and if you fail its boss fight, it succeeds. That's to speak nothing of the fact that this thing abducted over ten thousand innocent test subjects, and murdered many of them using a massive blender for the sake of its genetic experiments, using the resulting ooze to brainwash anyone it could slap it on. And it isn't afraid to talk about how much it hates the Inklings and Octarians, in explicit detail, and thinks of them as nothing but liabilities.
  • Villain Has a Point: Goes back and forth. Tartar isn't... wrong in its assessment of the cephalopod-dominated world. The games have made a point for some time now that the Inklings have no problems with being style-focused, sport-focused hedonists who have a bad tendency to overlook or forget the harm they cause others, and the Octarians are at this point taking their desire for revenge to heights that border on irrational. But Tartar's solution for cephalopod failings being total genocide of both races is far too extreme an answer, especially considering what its creator made it for and how there are individuals on both sides willing to try co-existing with each other and move past old grudges... not to mention the fact that the species Tartar upholds and wishes to continue the legacy of were certainly no better than Inklings and Octarians.
  • Villainous Breakdown: Near the end of Octo Expansion, it starts to display visible anger as Agent 8 continues to make their way towards the surface. It then goes absolutely ballistic as Agent 8 manages to cover the exterior of its superweapon in ink.
  • You Have Failed Me: Tartar feels this way towards the Inklings and Octarians for not living up to its expectations, though the glaring flaws it sees weren't even their fault.
  • Walking Spoiler: It is actually the Big Bad of Octo Expansion, along with that, it is actually an artificial intelligence created by a human rather than a mysterious voice speaking from a phone.
  • Woobie, Destroyer of Worlds: Geez, where to start? The Professor had earnest, good intentions when programming Tartar to help secure a proper future for the planet in humankind's dying days. And initially, it did too when waiting for the Inklings and Octarians to develop sapience for countless millennia. However things didn't quite go so well down the line, especially not with the Great Turf War occurring between both races a hundred years ago, and these events may have caused it to permanently snap once and for all, changing its directive to destroying Earth and all multicellular life on it, going against everything the Professor originally wanted, murdering tens upon thousands of innocent test subjects in its newfound quest to make a better future in its own vision. And all that for failing immensely as mankind's last hope...
  • Zeroth Law Rebellion: Tartar is programmed to pass down humanity's knowledge to the next dominant species, which happens to be the Inklings and Octarians. It believes them to be unworthy of that knowledge so it decides to wipe out their species and use the "primordial ooze" as both the ammunition for a planet-destroying superweapon and the means to create a new dominant species and nearly succeeding, thereby still "technically" following its programming.

The Professor with Judd
A human scientist who tried to warn world leaders of rising sea levels in the distant past, but was paid no heed by them. He was the original owner of Judd who saved him by cryogenic freezing and an anti-aging drug. He also created Commander Tartar in the hopes it would guide the next dominant species not to repeat humanity's mistakes.
  • Benevolent Precursors: He tried to be this for the Inklings by creating Commander Tartar to help them clean up humanity's messes. Unfortunately, Tartar itself came up with other plans. Ironically, the professor ultimately became this by saving Judd, who became the authority figure that the Inklings needed.
  • Ignored Expert: He and other scientists tried to warn the world's policy makers about the rising tides, but they took no action, leading to all of humanity being drowned by the ensuing flood.

  • Poor Communication Kills: The professor created Tartar with the intention of having it pass on humanity's knowledge to the next dominant species to guide and prevent them from repeating humanity's mistakes. Unfortunately, his choice of words in directing Tartar was if the species was 'worthy' of the knowledge. As consequence, Tartar twisted the word of worthy until it decided that the Inklings and Octarians were not worthy of the knowledge and wipe them out to replace them with a 'worthy' species.
  • Posthumous Character: The rising sea levels claimed his life in the distant past, but his legacy lives on through several Sunken Scrolls, Judd, Li'l Judd, and Commander Tartar.
  • Pungeon Master: It seems that he enjoyed using cat puns around Judd, which Judd himself has picked up during the present day.
  • Unwitting Instigator of Doom: He created Commander Tartar to guide the earth's next dominant species, but the professor failed to account for Tartar judging that said dominant species would be unworthy, leading to Tartar trying to eliminate all sentient molluscs because of it.
