Inkling

Inklings are a sentient race of squid-like humanoids who are the main protagonists in Splatoon.

Background
Inklings are evolved species of squid that came to be after rising sea levels sunk human civilization. Circa 2000 years before the events of Splatoon, the Inklings crawled up to what little habitable land there was left on the planet. The lack of space forced the Inklings to fight for whatever territory they could find, and the Turf War as a concept was established. The original Turf Wars were overseen by Judd, who was cryogenically frozen by his human owner before the Earth was flooded. 100 years before the events of Splatoon, the Inklings and the Octarians engaged in a Great Turf War. A young Cap'n Cuttlefish and the Inklings won, forcing the Octarians to retreat into Octo Valley.

Appearance
Inkings can alternate between a humanoid form and a squid form. At the age of 14, Inklings gain complete control over both these forms and can change at will. The squid form resembles a small, cartoony, monochromatic squid with eight small tentacles in the middle of their bodies, and two large ones on either side, resembling the hair of their humanoid form. It has relatively large head fins, and two upward-facing, human-like gray eyes. The undersides of their enlarged calipers are always white, regardless of what color the rest of them is, and they have a single large sucker on each. In this form, they are largely incompetent outside of their own ink, but when swimming in it, they can completely submerge into it and swim at speeds far greater than humanoid form's running speed. They can even jump out of the ink to cover further distances and swim up ink-covered walls. However, this form is also largely vulnerable, as being inside of enemy ink in this form will eventually splat an Inkling.

The humanoid form has a black markings that resemble swim goggles or heavy eyeliner around their eyes, pointed ears analogous to the squid's fins, and "hair" that resembles a squid's tentacles, which changes color according to their ink color.. This color is randomly selected out of predetermined pairs, some of which can be found in. Their mouths contain human-like teeth, as well as three larger sharp teeth, two on the top and one on the bottom, which resemble a squid's beak. The inside of an Inkling's mouth matches their ink color as well. Inklings have no bone structure, making their teeth possibly the only truly solid part of their body, just as the only solid part of a squid is its beak.

Inklings are customizable. If the player chooses a girl Inkling, their Inkling will have thin eyebrows and two long tentacles that hang from both sides of the head in front of the ears. A boy Inkling has noticeably larger eyebrows and two tentacles tied in a ponytail at the back of his head, tied together with a brown, yellow, and green band. Each Inkling has ten tentacles total: six head tentacles (two long and four short), and four limbs. Skin color, gender, and eye color can be changed in the options menu at any time. Head accessories, shirts, shoes, and weapons can be changed to the player's liking in the equip menu. Many clothing items change to match the Inkling's current color. Both forms have a slightly different pitch to their voice.

Inklings take on a unique appearance when they have a Special Weapon ready: they will give off sparks, the tentacles on their head will become very brightly colored and will glow, bubbles will form at the top of their head as if from boiling water, and they will appear to be caught in a strong wind even when completely still. Their appearance goes back to normal once their Special Weapon has been used.

Abilities
Both of the Inklings' forms have abilities associated with them. In humanoid form, Inklings can splatter a special type of colored ink by using various weapons, including guns, rollers, buckets and paint brushes. This ink can be quickly spread over many surfaces, with the exception of green barrel-like objects, black pavement, and Glass surfaces. This ink inhibits the movement of Inklings that do not have a matching color. When used as a projectile, ink can damage opposing Inklings, eventually "splatting" them and forcing them to respawn. In squid form, an Inkling can swim and jump quickly through ink of the same color, even using this mechanic to swim up walls and through wire fences and grates into areas that are not typically reachable. However, squids cannot travel past striped barriers, preventing them from swimming into inaccessible areas. While squid form Inklings are in their own ink color they will be invisible if they stay still, and when moving only slight ripples will appear. While submerged in ink of their own color, they quickly replenish their ink ammunition. When squid form Inklings are on dry land they are only able to slither slowly, even slower then a humanoid Inkling.

Inklings are unable to swim in water. When submerged, their body dissolves for unknown reasons, leaving their clothes behind. The official American Splatoon Tumblr has mused that this may be because their bodies are actually made of liquid. Another reason to support this is that squid form Inklings can go through grates, but since squids don't have bones then it might just be that they can easily fit through the holes.

Inklings are capable of giving off light, possibly from bioluminescence, an ability some real-life squid such as the firefly squid possess. In the dark, either during a Splatfest or some Octo Valley missions, the player's Inkling will glow brightly in humanoid form, lighting up the area immediately around them. This glow disappears entirely upon assuming squid form. Other Inklings remain dark, helping to differentiate them from the player's. However, all Inklings (as well as jellyfish) in Inkopolis Plaza do give off a very faint glow during a Splatfest, seen only on the ground around them.

Communication and language
Inklings communicate with each other in the Inkling language, which sounds like indecipherable, high-pitched gurgling. They can be found talking to each other in Inkopolis Plaza. Written Inkling appears frequently in-game: on signs, in Sunken Scrolls, etc. The Squid Sisters talk and sing in Inkling. Inklings speak to teammates in Inkling when Signals are used in online battles.

So far, there have been no successful attempts at decoding the language, leading some to believe it is gibberish.

Culture
Inkling culture has been heavily influenced by the ancient human cultures that came before them; As a result, Inkling architecture, fashion, art, and even the Inkling written language shows influence from Japanese, American, and other ancient human societies. It was implied that Inklings adapted much their own culture and mannerisms from the cities and towns they've taken as their own, and the fossils of human civilizations they have unearthed. Though much of their culture has been appropriated from humans, the Inklings have their own modern rendering on certain subjects, as well as cultural ideas of their own. Turf Wars as a sport are cultural high-point to many Inklings, with many youngsters participating in turf war events as a means of entertainment and relaxation. Turf wars also can be seen as a means of recreation and celebration, since the the Inkling victory of the Great Turf War.

Fashion is a major part of Inkling societies, to the point of coining the term "fresh" to signify how recent and cool Inkling attire and general style is. Freshness can be applied to many other aspects of Inkling life, such as firearms and linguistics. Heavy focus on Inkling gear is commonplace, as Inklings will spend lots of their time and Cash shopping for new and interesting headgear, clothes, and shoes. Inklings can be seen gathered both inside and outside of local shops, socializing and buying themselves new gear.

Inkling music can be heard throughout Inkopolis, from the rock band Squid Squad, to the worldwide pop idols Squid Sisters. Many bands have members from completely different species, such as the anemone and lobster members of Chirpy Chips, but the music industry seems to be largely comprised of Inklings.

Splatfests, a tri-weekly event that brings Inklings together for a large concert and celebration of two opposing ideas, and can be seen as a merging of music and turf wars. Two teams are formed around two opposing topics (such as Cats versus Dogs), and compete in turf wars against each other. The more popular and/or the higher scoring team wins. All the while, the Squid Sisters perform for 24 hours straight. Miiverse posts by participating Inklings is highlighted during the event, showing up on billboards in the concert area and around the selected stages for that event.

Squidmas
Squidmas is an Inkling holiday that is assumed to be celebrated in the winter. Much is unknown about this holiday aside from its obvious likenesses to the human holiday of Christmas. From this it is assumed that in the winter, a figure named Father Squidmas goes around the world giving out presents and freshness to all the good Inkling children. According to Callie of the Squid Sisters, Father Squidmas can be found in the North Pole of the Earth, making gifts all year in preparation for Squidmas time.

It is unknown if there are other Inkling holidays, or if they parallel to human holidays.

Squidmas is an additional element associated with the localization. Japanese edition originally doesn't have it, and also other regions may not have it.

Splatting
While in battle, Inklings can use their weapons to splat each other with ink. Standing in enemy ink will damage and slow an Inkling, but only enemy fire is able to splat an Inkling. When splatted by an enemy, Inklings explode into enemy ink, their gear and weapons drop, and a ghost-like squid figure will rise into the air where they were splatted. Inklings can also be splatted from trying to swim in water and dissolving or falling off a ledge and exploding into a cloud of their own ink. Inklings respawn at Checkpoints after being splatted in both Octo Valley and online battle modes. It is unknown whether or not being splatted is another term for dying and Inklings simply respawn after death, or if Inklings can actually die through other means.

Trivia

 * According to the EDGE article, Inklings get full control of their squid and human forms at age 14. Since the playable Inklings seem to have full control of their squid and human forms, one can assume that they are at least 14 years old.
 * An Inkling's ink color is random online unless the Ink Color Lock option has been turned on, while in Octo Valley, it depends on the chapter.
 * The developers said when they came up with the concept, they didn't consider Bloopers from the Mario series, despite the close resemblance between Bloopers and Inklings.
 * A trophy of a female Inkling appears in Super Smash Bros. for Nintendo 3DS and Wii U, which becomes available after downloading the Inkling Mii Fighter costumes.
 * The trophy is actually shaped like the Inkling Girl amiibo.
 * When switching between gear on the equipment screen, there is sometimes a small delay before the selected piece of gear appears on the player's Inkling. For that moment, they will not be wearing any gear in that slot, which, for clothing, reveals that they wear a the tight, sleeveless black shirt by default. For shoes, it shows their bare feet, which are flipper-like and featureless because of the fact that Inklings' feet are meant to never be seen. For headgear, they simply look like they are wearing the Fake Contacts, or no headgear.
 * When designing the Inklings, the Splatoon development team centered around the girl at first, to the extent that they thought at first to not have a boy Inkling. They emphasized on the girl Inkling because there weren't many female leads in Nintendo games, and that having a strong, active female lead would make it easier to become accepted overseas. The boy Inkling was created later.
 * The Squid Research Lab admitted that Inklings may be made entirely out of ink. This theory would explain why Inklings dissolve in water, swim through grates, and reform with ease after being splatted.
