History Fanon / YuriOnIce

** The question of if Yuri is gay or bisexual actually leads to a lot of arguments in the fandom, mostly depending on how people interpret his skating for Yuko in episode 1. On the other hand, it seems generally agreed-upon in the fandom that Victor is completely gay, because of his general [[CampGay flamboyant demeanor]] as well as the visual references in his costumes to famous gay figure skaters such as Johnny Weir and Jeffrey Buttle.

* Yuri is often portrayed as a SexGod in fanworks, probably due to a combination of his ''eros'' persona, his LauncherOfAThousandShips status, Victor's mention of his stamina, and of course, [[spoiler: the pole-dancing]].
* Yuuri has never referred to Victor with [[UsefulNotes/JapanesePronouns a direct second person pronoun]] and only ever uses his name. However, many fans in the Japanese fandom let him use "anata" occasionally in fanart and doujinshi, whether they ship Top!Victor or Top!Yuuri. As for Victor, he had referred to Yuuri as both "omae" and "kimi", but he used "kimi" more often, so it's usually the go-to pronoun for the Japanese fandom when they want Victor to call Yuuri by something other than his name.

* While it's ambiguous in the show itself, most of the fandom agree that Victor SleepsInTheNude, based on how he's always at least naked from the waist up (with his blanket covering his lower body) the two times we see him sleep in Yuuri's house.

* The exact sexualities of characters are not mentioned in-series, however EveryoneIsGay is the default for most of the cast. If a character has shown attraction to another gender then they're depicted as bisexual.

* It's fairly common in both the Japanese and English-speaking fandoms to portray Yurio as an older brother figure towards the Nishigori triplets, since he's already friends with their mother Yuko (and this is partly fueled by Yuko texting Yurio a photo of both of them with the triplets in Episode 4).

* Minako and Lillia have never interacted in the series itself, or at least not on-screen, and there's no indication that they know each other. However, fanfics tend to portray them as having a history with each other or even being best friends (or eventually becoming something more) due to both having been famous ballerinas in their youth.

* Minako and Lilia has never interacted in the series itself, or at least not on-screen, and there's no indication that they know each other. However, fanfics tend to portray them as having a history with each other or even being best friends due to both having been famous ballerinas in their youth.

* Japanese fanon tends to portray Yuko as a YaoiFangirl who {{nosebleed}}s over any romantic interactions between Yuri and Victor. In canon, the only times she gets a nosebleed are just over Victor, who she's a [[{{Fangirl}} a big fan of]] (once when he sends a smolder her way when he's demonstrating the ''Eros'' program, and again when she sees Yurio wearing one of Victor's old costumes).

* Yuuri has never referred to Victor with [[UsefulNotes/JapanesePronouns a direct second person pronoun]] and only ever use his name. However, many fans in the Japanese fandom let him use "anata" occasionally in fanart and doujinshi, whether they ship Top!Victor or Top!Yuuri. As for Victor, he had referred to Yuuri as both "omae" and "kimi", but he used "kimi" more often, so it's usually the go-to pronoun for the Japanese fandom when they want Victor to call Yuuri by something other than his name.

!!Confirmed
* Some fans believe that Yuri has some issues related to his weight and some self image issues whenever this is brought up, though fans like to believe that Victor finds Yuri's chubby body either adorable or sexy. Eventually, it's revealed that Victor finds it to be the former.
* Once it was revealed that Otabek had previously trained in Canada and the U.S., a lot of fans speculated that he might have been friends or, at least, known or shared a rink with J.J. Official material confirmed this, although it also mentioned that they drifted apart over the years.
* There are several fans (with some merit) who like to portray Phichit as a ShipperOnDeck to Victor/Yuri [[spoiler: which actually becomes canon considering his reaction to their engagement in Episode 10]].
* J.J. had been speculated to be a devout Christian by fans, due to him crossing himself before skating. It was later confirmed by Sayo Yamamoto in an interview, along with that J.J. and Isabella are saving sex for after marriage.

!!Others
* Some fans believe Phichit and Yuri had a romantic and/or sexual involvement while they were roommates or that Phichit had a crush on Yuri.
* Plenty of people like to think that Christophe wants to sleep with Victor or Yuri. [[AThreesomeIsHot Or both]]. There's also an almost unanimous belief that, at one point or another in the past, Christophe and Victor have slept together.
* While Victor and Chris are shown to be friends and have a history together in the show, the "best friends who are always calling each other and asking for advice on their relationships" part is largely invented by the fandom. In particular, a lot of fanworks suggest that Victor confided in Christophe about his feelings for Yuri after the banquet. To a certain degree, this is also true of how fanworks interpret Yuri's friendship with Phichit; while they do consider each other their best friends, Yuri seemingly didn't call Phichit for months after he left Detroit, and first does it in order to ask a favor.
* Some fans tend to theorize that besides Yuri [[spoiler: grinding on Victor]] in Episode 10, they [[spoiler: had a one night stand afterwards, or came close to it]], since it would cause Victor's unusually forward manner of displaying physical affection (which can get a little overboard at times) to make much more sense.

* While Victor confirms that he had previous relationships, a lot of fans think [[spoiler: Yuri]] is his first serious relationship or at least, his first time falling in love. The latter seems to be supported by Victor talking about "neglecting life and love for 20 years" in episode 10.

* A lot of people believe that Yurio calls, or will call, Otabek by the nickname "Beka", a common nickname in Kazakhstan for men with names finishing in "bek". Similarly, people believe that when he grows older, his hair will become increasingly longer, possibly even with some braids and will grow taller than Otabek. Similarly, some believe that Otabek would call Yurio "Yura" or "Yuratchka".
* Fans tend to agree that after their careers end, the most likely thing is that Yuri would start teaching skating for young kids while Victor would start coaching older kids. To a lesser degree a lot of people believe they'll have two kids, possibly twins.

* While this may go into WMG territory, several fans claim that [[spoiler: the Barcelona Grand Prix Final was rigged, since the official material containing the scores to the characters' programs (particularly with Yuri and Yurio) do not match up to the scores shown in the series, and there is no way that it could have been a mistake on the writers' part]].

* While it's ambiguous in the show itself, most of the fandom agree that Victor SleepsInTheNude, based on how he's always at least naked from the waist up (with his blanket covering his lower body) the two times we see him sleep in Yuuri's house.
* Yuuri has never referred to Victor with [[UsefulNotes/JapanesePronouns a direct second person pronoun]] and only ever use his name. However, many fans in the Japanese fandom let him use "anata" occasionally in fanart and doujinshi, whether they ship Top!Victor or Top!Yuuri. As for Victor, he had referred to Yuuri as both "omae" and "kimi", but he used "kimi" more often, so it's usually the go-to pronoun for the Japanese fandom when they want Victor to call Yuuri by something other than his name.

* The exact sexualities of characters are not mentioned in-series, however EveryoneIsGay is the default for most of the cast. If a character has shown attraction to the opposite gender then they're depicted as bisexual.

* A lot of people have become more and more interested in the idea that Victor and [[Manga/{{Haikyuu}} Lev Haiba]] are related, due to the fact that they're both Russian ([[ButNotTooForeign half in Lev's case]]), and have short, light gray/silver hair. It helps that the the fandoms of both series are good friends (see FriendlyFandoms below).

* There's a pretty intense fan discussion about whether the BigDamnKiss was [[spoiler: Yuri and Victor]]'s ''actual'' first kiss or just their first ''public'' kiss. Given [[spoiler:Yuri]]'s increasingly receptive and comfortable attitude toward [[spoiler:Victor]]'s handsier and more flirtatious behavior, especially in public (like [[spoiler:Victor]] getting half-naked and basically molesting [[spoiler:Yuri]] after too many drinks before the Cup of China), [[https://hannicanny.tumblr.com/post/153032904690/reasons-why-i-think-yuuri-and-viktor-have-already some fans have speculated]] that they were already in a sexual relationship several episodes before their official RelationshipUpgrade. It doesn't help that [[http://lookiamnotcreative.tumblr.com/post/153468260932/lost-in-translation-on-ice-translation-mistakes with a bit more knowledge of Japanese]], it's clear that several commentators and other skaters already think the two are involved.

** Fans at least generally agree that [[spoiler:Victor]] was his first serious relationship. Those who don't see [[spoiler:Yuri]] as a virgin tend to think he got it out of his system through drunken one-night stands or friends-with-benefits type situations (possibly with Phichit). This seems supported by the teasing Yuri gets about his lack of relationship experience.

* Some fans believe he and Yuri had a romantic and/or sexual involvement while they were roommates or that Phichit had a crush on Yuri.

* There are several fans (with some merit) who like to portray Phichit as a ShipperOnDeck to Victor/Yuri [[spoiler: which actually becomes canon considering his reaction to their engagement in Episode 10]].
