History Fanfic / OneX

* ForWantOfANail:
** The prime nail is the fact that, when U.A. was established, it was decided to split all classes between genders so as to fall more in line with single-sex schools prior to the Dawn of Quirks, the class names changed to "X" and "Y" to reflect the chromosomes. Since then, while all other courses have returned to being co-ed, the Hero Course remains split between genders, Izuku only being in Class 1-X due to Tatsuma pulling some strings to get him in her class out of concern that Aizawa would just write him off as a lost cause.
** As Tatsuma opts to let the class get to know each other first before jumping right into training, everyone learns each other's names right off the bat. This, combined with Bakugo not being in their class, means Ochako never mistakenly believes Izuku's name to be "Deku", nor does she end up redefining it for him. "Deku" instead remains a derogatory term, and Ochako calls Izuku "Zuku".
** Thanks to taking a more gentle approach and seeing in Izuku a kindred spirit regarding their Quirks, Tatsuma suggests Izuku try ''communicating'' with his Quirk rather than simply find a way to not break his bones as Aizawa did in canon. As a result, Izuku focuses less on trying to reallocate the excess energy of One For All in favor of trying to commune with the inner Vestiges, allowing him to unlock Black Whip much earlier instead of attaining Full Cowl.
** Bakugo doesn't learn Izuku made it into U.A. until over a week into the school year, meaning the principal of Aldera never brought them both to his office to congratulate them and Bakugo never threatened Izuku immediately afterwards. As a result, he still thinks Izuku is a Quirkless weakling he can intimidate, and Izuku, not having had to stand up to him this time around, still sees Bakugo as his tormentor and freezes up as a result.
** Since Iida isn't friends with them here due to being in Class 1-Y, Izuku and Ochako are left at the mercy of the panicking students trying to flee the cafeteria, no one managing to alert everyone it's just the press until Nejire and Yuyu show up later. As a result, several of the girls end up trampled in the chaos, Koko suffering the worst of it after being knocked to the ground.
** Thanks to having unlocked Black Whip and not simply breaking his bones to use One For All, Izuku doesn't gain a reputation as a "mad man" during the Sports Festival, nor are Midnight and Cementoss as ready to try and intervene to stop him from hurting himself. He instead gains the moniker of the "Prince" of 1-X thanks to being the only boy in the class, and his effective yet respectful behavior when facing his opponents.
** When Izuku managed to reach Shoko and convince her to use her fire, thanks to Shoko's AdaptationPersonalityChange making her more HotBlooded beneath her icy exterior, she doesn't anchor herself to the ground during their final clash, sending ''both'' Izuku and Shoko out of the arena and into the walls. The both of them actually try to get up and keep going, but Midnight ruled the match a draw rather than let them continue injuring themselves.

U.A., the most well-renowned Hero School in all of Japan. Izuku Midoriya managed to make it in and was all set for his first day as part of Class 1-X. He only had one question: why was he in the girl's class instead of the boy's?

* AdaptationalNationality: In canon, there's little indication Hanta Sero is anything but pure Japanese. Here, Hana introduces herself as half-Japanese via her father, half-Korean via her mother.

** The girls of 1-B all receive more focus by virtue of being Izuku's classmates this time around. Of special mention is Pony and Itsuka, the former becoming Izuku's best friend after they initially bond from Izuku being able to speak English, and the latter being someone Izuku considers a leader and looks to for guidance.

** The students in Class 1-Y are largely relegated to cameos outside of Bakugo, the only one to get any significant appearances aside from him being Honenuki due to his match with Izuku in the first round of the Finals. Others though like Kaminari, Tetsutetsu, Iida, and Mineta only get namedrops or passing appearances. Chapter 17 would see Izuku properly interacting with Honenuki and Kaminari while featuring cameos of Kamikiri and Mineta, but said interaction lasts for a third of the chapter, and its made clear that they could at best be considered "acquaintances" of Izuku's compared to some genuinely being his friends in canon.

''[[https://archiveofourown.org/works/36908902/chapters/92082598 1-X]]'' is a ''Franchise/MyHeroAcademia'' fanfic by [[https://archiveofourown.org/works/16124588 Nanocowie]] on Website/ArchiveOfOurOwn. Inspired by the oneshot ''[[https://archiveofourown.org/works/34123255 Belonging]]'' by [=SonnieCelanna=], it explores how things could radically change because of a single rule regarding students at U.A. established long ago: all Hero Course classes would be separated by gender.

** While all of the {{gender flip}}ped students had their given names changed to be more feminine, Koko's stands out due to her canon given name now being her family name. In canon, his name was "Koji Koda", with "Koda" being his family name and "Koji" his given name. Here, her name is "Koko Koji", with "Koji" being her family name and "Koko" being her given name.

** As Tatsuma has the students introduce themselves by their actual names rather than jump straight into the Quirk Apprehension Exam, Ochako never mistakenly believes Izuku's name to be "Deku". Without her redefining the name for him, the two initially remain just classmates compared to quickly becoming best friends like in canon. This is something Ochako laments about after she can only watch Izuku be accosted by Bakugo in the cafeteria, since she ''wants'' to be friends with Izuku, but hadn't had the chance to do so. They slowly begin growing closer following the USJ, even if not to the extent in canon, as Pony takes the position of Izuku's best friend instead, with Ochako instead being his second closest friend similar to Iida's canon spot.

** Due to not being classmates this time around, Kaminari's relationship with Izuku and Kyoka is different. Canonically, Kaminari and Izuku didn't have much in common, but could still be rather good friends with each other, while Kyoka largely served as TheGadfly to him and the two acted as VitriolicBestFriends, with the occassional bouts of ShipTease. Here, Izuku barely knows him, so he can't fault Shoko for being disgusted at his "fight" with Mei and accidentally disrespecting everyone by not taking the tournament seriously, and Kyoka's more just resigned to his antics after he tried [[RomanticFalseLead hitting on her]] during the Sports Festival, with Nanocowie all but saying in a comment that [[https://archiveofourown.org/comments/620496793 Kaminari will not be paired with Kyoka, but Mei instead]].

** {{Play|ingWithATrope}}ed with regarding Shoko Todoroki. She possesses a sense of entitlement and haughtiness that Shoto didn't have in canon, internally considering herself better than all of her classmates and desiring to show them "their place" so that they can be part of ''her'' agency when they graduate, expressing irritation at the idea of Izuku not wanting to be on her team in the Cavalry Battle in favor of proving his own merit. She demonstrates a SugarAndIcePersonality outside of that though, willing to be soft-spoken and friendly with her classmates, letting her become quick friends with Ochako after their match in the Sports Festival, but harsh and cruel to those outside of it, as she demonstrates when she {{curb stomp|Battle}}s Kaminari and calls him pathetic for his "match" against Mei. Nanocowie has stated this was a deliberate [[ForWantOfANail nail]] they wanted to explore, that while Shoko still suffered abuse under Endeavor and his training, she ended up gaining a sense of superiority as a means of coping this time around compared to Shoto's [[NoSocialSkills lack of social graces]], outright stating Shoko is a "himedere", in that she wants to be treated like a princess even if she isn't one, Izuku even noting it was as if Endeavor himself was constantly over her shoulder whispering in her ear how she was ''better'' than everyone else. When Izuku manages to break down her barriers and get her to use her fire, she displays a more HotBlooded demeanor and maintains a level of self-confidence, calling Izuku her "prince" and meeting his challenge head on, just without the haughtiness this time.
** Since he never received a helping of HumblePie from Izuku outsmarting him here, Bakugo is still an arrogant and domineering [[TheBully bully]] when he makes his debut here, and hasn't realized he was a NormalFishInATinyPond back at Aldera. [[spoiler:He only begins to realize this after he's defeated by Pony in the first round of the 1v1 matches.]]

* AmbiguouslyBi: Shoko Todoroki. She shows clear signs of romantic interest in Izuku, but when Izuku is later talking to Ochako after she and Shoko fought in the Sports Festival, Ochako says [[AffectionateNickname 'Roki]] "likes" Ochako. While Izuku believes Ochako meant "as a friend", Ochako then says she "likes" Izuku too but has competition for him, much to his [[CluelessChickMagnet confusion]]. It's ambiguous if Ochako is using "likes" in the same manner when referring to herself ''and'' Izuku, making Shoko bisexual, or if its a case of AmbiguousSyntax.

* CommonalityConnection: Izuku and Pony quickly hit it off once Izuku reveals he can not only understand Pony, but speak English himself, the two regularly having entire conversations in English while others can only guess what they're talking about. Add on the two of them finding common ground in being massive hero nerds and Pony standing up to Bakugo for Izuku's sake, the two quickly become close, with Izuku even considering Pony his new best friend.
* DarkHorseVictory: Bakugo was highly favored to win the Sports Festival due to being TheAce of Class 1-Y and placing highest on the Entrance Exam, Present Mic outright stating a special betting site has him as the one to win. [[spoiler:Pony]] beats him in the first round of the finals instead, leaving everyone, including Midnight and Present Mic, stunned beyond belief, the latter even struggling to find words at what just happened.

** As Tatsuma opts to let the class get to know each other first before jumping right into training, everyone learns each others names right off the bat. This, combined with Bakugo not being in their class, means Ochako never mistakenly believes Izuku's name to be "Deku", nor does she end up redefining it for him. "Deku" instead remains a derogatory term, and Ochako calls Izuku "Zuku".

** Thanks to having unlocked Black Whip and not simply breaking his bones to use One For All, Izuku doesn't gain a reputation as a "mad man" during the Sports Festival, nor are Midnight and Cementoss as ready to try and intervene to stop him from hurting himself. He instead gains a moniker of the "Prince" of 1-X thanks to being the only boy in the class, and his effective yet respectful behavior when facing his opponents.

* GenderFlip: Since the fic established that each class is comprised of 20 students, and that canonically there were only ''13'' girls between Class 1-A and 1-B, Nanocowie decided to change six of the boys into girls, picking Shoto Todoroki, Eijiro Kirishima, Fumikage Tokoyami, Rikido Sato, Hanta Sero, and Koji Koda, becoming Sho''ko'' Todoroki, Ei''ko'' Kirishima, Fu''tako'' Tokoyami, Rik''a'' Sato, Han''a'' Sero, and Ko''ko'' Koji.

* OpenMouthInsertFoot: Aizawa ends up perpetually badmouthing Izuku while commentating on the Sports Festival, seemingly festering a grudge over being unable to expel him on day one thanks to Tatsuma putting Izuku in her class. As many point out, it will just end up backfiring on him if Izuku does well in the Sports Festival, which he does indeed, managing to tie for first place against Shoko. The end of the Sports Festival even has Tatsuma decide to give him a BitchSlap for talking shit about Izuku and having it blow up in his face.

* WhatHappenedToTheMouse: Following the USJ, while it's mentioned that Ochako and Futako were taken to the hospital for their injuries, no mention is given as to the status of Thirteen. While it's later said that there were no hero casualties at the USJ, Thirteen's condition is left unsaid, leaving unclear if she was hospitalized too like in canon or made it out of the USJ unscathed this time.

* HaremGenre: Nanocowie has confirmed the fic to be a harem style fic, albeit a slow-burn style to properly flesh out Izuku's relationship in particular. So far, the only outright confirmed member is Pony, and while not outright confirmed, Izuku has received moments with most of his class, in particular Ochako, Itsuka, Momo, Kyoka, and Koko.

She possesses a sense of entitlement and haughtiness that Shoto didn't have in canon, internally considering herself better than all of her classmates and desiring to show them "their place" so that they can be part of ''her'' agency when they graduate, expressing irritation at the idea of Izuku not wanting to be on her team in the Cavalry Battle in favor of proving his own merit.

** {{Play|ingWithATrope}}ed with for Ochako. Following the USJ, she ends up letting her Kansai accent show and takes on a more boisterous persona, which inadvertently makes her look aggressive and unsympathetic to the rest of Class 1-X regarding their trauma, even nearly causing a fight with Itsuka. Izuku is quickly able to defuse it though, having realized her new persona is her own way of coping and trying to help the others, convincing her she needs to let the others cope at their own pace while making clear he understands her intent. He still expresses concerns about her hiding her trauma BeneathTheMask, but Ochako waves it off in favor of trying to push forward.
