History Fanon / Splatoon

* Shiver's preferred weapon class is often seen by fans to be Splatanas, since she has a Japanese aesthetic to suit the sword-like nature of that class. The game actually points to her being a Stringer main, since she talks about using them in stage rotation dialogue and has Stringers (not Splatanas) in her Tableturf deck. This continues in the ''Side Order'' DLC, where the preset weapon loadout based on Shiver uses the Tri-Stringer as its main weapon.

* The violinist of Bottom Feeders is feminine looking but looks like a [[AnimalGenderBender male]] Betta fish. Fan consensus is that they're either a [[DudeLooksLikeALady effeminate looking male]] or a UsefulNotes/{{transgender}} person.

* A fan theory regarding Frye's often mentioned little brother is that they're actually Baker, the inkling bassist of C-Side. While Baker's tweets in the ''Splatune 3'' booklet has him describe Deep Cut as strangers, there's not much evidence to suggest this is either true or untrue.

* In [[https://splatoon.nintendo.com/en/news/interview-shiver-frye-and-big-man-of-deep-cut-will-steal-your-heart/ the official site's interview with Deep Cut]], Big Man claims to be a fan of "this one DJ from Inkopolis." Although this could refer to a number of characters, such as [=SashiMori's=] Paul or Diss-Pair's Mashup, fans generally assume this is referring to Marina, who is the most significant character of that description by far. This may have been confirmed by the 2024 Deep Cut concert, where Big Man finally gets a chance to sing alongside Marina. The lore surrounding the Splatfest song "Suffer No Fools" also involves Big Man being left star-struck when he hears Off the Hook is planning a concert in Splatsville, further hinting that the "DJ from Inkopolis" is Marina.* As of the Wealth vs Fame vs Love Splatfest, it's common to read Frye as a SadClown of sorts, who remains chipper on the surface but barely hiding that the repeated Splatfest losses are getting to her. It doesn't help that her chipper attitude in thanking her teams has become a lot more subdued since the Shiver vs Frye vs Big Man Splatfest.

* Before the ''Octo Expansion'', Western fans generally assumed that everyone knew Marina was an Octoling and that ([[FantasticRacism most]]) didn't care. In canon, few people outside of the New Squidbeak Splatoon are familiar enough with Octarians to recognize that she was one, and so think that [[FailedASpotCheck she is an "exotic" looking Inkling]].[[note]]Though the third game would effectively retcon this to apply only to Inklings from Inkadia, [[LaterInstallmentWeirdness since the Splatlands have an Octoling population going back several generations]].[[/note]] This even extended to Pearl in the original Japanese; the English localization didn't get that memo, and so Pearl had [[DubInducedPlotHole already alluded to knowing]] on multiple occasions before that point. The team's fix for this was for Pearl to make Marina's ex-military status the real surprise for her, while she already knew Marina as an Octoling, but didn't know how to broach the subject. A fair number of Western fic writers would end up running with the idea of Pearl being a SecretSecretKeeper as a result.

* Most fans agree that Marina and Pearl live together, and this is often in conjunction with them also being a couple, based on [[LesYay the romantic undertones in some of Marina's dialogue]]; especially in Japanese, where she more regularly shows admiration towards Pearl and her official character biography describes her as a "maiden in love". While nothing official has been said on their relationship, the interview included with the Japanese ''Octotune'' soundtrack jossed the roommates theory and Marina mentions having a landlord in the North American version of ''Splatoon 2'', though it's implied Marina regularly stays at Pearl's house regardless.

* Another headcanon is that all the playable agents are canonically female, mainly due to the female versions (the default female Inkling in New Agent 3's case) being featured prominently in promotional material and the developers referring to them as such in interviews. This is seemingly confirmed in the case of the original Agent 3, as their default appearance in later games is always that of the ''Splatoon 1'' female Inkling (though GenderInclusiveWriting is naturally still used).

* There's a common belief that Acht (a.k.a DJ [=Dedf1sh=]) and DJ Paul of [=SashiMori=] are connected in some form, mainly coming from the fact both wear hats with the same logo (a stylized octopus). The Haikara Walker magazine outright calls attention to this, theorizing the two could either be blood relatives, or simply follow the same brand. The former interpretation is the most popular, with Paul being thought to be Acht's younger brother.

* The Parallel Canon boss fight is implied to be a result of ||Smollusk|| getting hold of Marina's data on Agent 4 as her security chief. However, fan creations often depict the main Inkling in that boss as actually ''being'' Agent 4 themself, BrainwashedAndCrazy in a similar manner to the Sanitized Agent 3 fight from ''Splatoon 2''.

* Shiver's preferred weapon class is often seen by fans to be Splatanas, since she has a Japanese aesthetic to suit the sword-like nature of that class. The game actually points to her being a Stringer main, since she talks about using them in stage rotation dialogue and has Stringers (not Splatanas) in her Tableturf deck.

* As Pearl's full name is only revealed in the original Japanese (where she is Hime Houzuki), fanon has taken to using Houzuki as her last name in English as well.
