Leave for Mendeleiev is a Miraculous Ladybug fanfic written by imthepunchlord on tumblr. They co-created the AU along with zoe-oneesama and miraculouscontent.

Marinette is dreading the new school year, another year of having to share a class with her bully, Chloe Bourgeois. However, things look up when she finds out she's actually going to be in Ms. Mendeleiev's class, rather than Bustier's. Hence, no Chloe.

Leave for Mendeleiev contains examples of:

  • Accentuatethe Negative: Anything and everything having to do with Adrien.
  • Adaptation Relationship Overhaul: Since she's not part of Bustier's class anymore, Marinette doesn't have particularly close connections to anyone in it, and is building friendships with members of Mendeleiev's class like Aurore, Jean and Ondine instead.
    • Chloe has developed a sort of Super-Persistent Predator attitude towards Marinette due to the transfer. Having gotten used to Marinette being readily accessible (and getting away with all her bullying due to Bustier's lax methods), she's determined to prove that Marinette can't get away from her so easily.
    • Marinette doesn't have any kind of crush on Adrien, and he in turn barely registers her existence, only taking an interest when he thinks she might be Ladybug.
  • All Love Is Unrequited: So far. Aurore has a crush on Adrien, but he only started paying attention to her because Ladybug was dropping hints. It seems he was only paying her any attention because she might have had a connection to Ladybug, but after the events of The Gamer, he's been drifting.
    • Adrien/Chat Noir still retains his crush on Ladybug, but she doesn't reciprocate for either party.
  • Alpha Bitch: Chloe, who isn't especially thrilled that her favorite victim isn't stuck in the same class as her and repeatedly attempts to reassert her power over her.
  • Armor-Piercing Response: This exchange between Chloe and Ms. Mendeleiev when the teacher catches her cornering Marinette:
    Chloe: "Do you know who I am?"
    Mendeleiev: "Do you know who I am? I am the meanest teacher in this school, and if I find you disrupting my class again, I'm going to see to it that you get suspended. Now, out!"
    • When Chat attempts to play off Ladybug's anger post-interview and insists that the two of them are meant to be together, Ladybug throws him for a loop with four little words: "I don't love you."
    • After the Ladyblog gets some serious backlash following the Face to Face incident, Marinette tries to help Alya calm down, leading to this exchange:
      Marinette: "I think it's for the best. Ladybug doesn't want her identity revealed, and—"
      Alya: "American heroes don't mind!"
      Marinette: "A lot of those American heroes revealed themselves of their own consent. Has Ladybug ever consented to revealing herself?"
  • Ascended Extra: A few, but most notably, Aurore Beaureal. In canon, she was an akuma in two episodes, but otherwise remains in the background. Here, though, she becomes Marinette's new best friend, standing up to Chloe and Alya for her. She also models clothes and accessories for Marinette. Marinette, in return, supports her at the Weather Girl competition, designs clothes and accessories for her, and helps her try to win Adrien's affections.
    • Jean Duparc was originally a background character whose akuma was mentioned in Princess Fragrance. Now, he's one of Marinette's new friends, who's a bit of a trickster, and tends to get under Aurore's skin a lot. Despite that, he still tries to support her at the Weather Girl competition and also in trying to win over Adrien.
    • Advertisement:
    • Felix and Amber are based off of characters from the earliest concepts for Miraculous Ladybug, with the latter being based off of Chloe's concept art.
    • Ondine. As of season three, she's only made major appearances in "Syren" and the Heroes' Day two-parter, not even interacting with Marinette in their civilian identities. Here, she commissions Marinette for the banner for Alix and Kim's race, swaps stories about their love woes, and gives Marinette her stuff back when Alya takes it.
  • Broken Pedestal: Adrien loses Aurore's regard for good when he attempts to prevent her from intervening in Chloe's bullying, declaring that it's better to let Chloe harass them than risk the Alpha Bitch turning into an akuma.
  • Character Derailment: Adrien is a well meaning if naive boy in Canon, not so here. While he never apologized for Copycat he knew it was his fault, hence his desire to fix it.
    Chat Noir: "This is my mess. I'll clean it up."
  • Demonization: Adrien is given this treatment.
  • Demoted to Extra: On the other hand, characters in Bustier's class, while relevant for the akuma of the week plots, are out of focus.
  • Digging Yourself Deeper: When Ladybug finds out what really caused Copycat and confronts Chat about it, Chat attempts to change the subject. At no point during the confrontation does he actually bother apologizing for how he lied, more focused on asserting that their relationship is inevitable.
  • Die for Our Ship: A product of the author's "anyone but Adrien" mentality.
  • Double Standard: Adrien's flaws are called out while Marinette's (by virtue of the setting) are ignored.
    • Adrien not returning Aurore's feelings is treated as proof that he wasn't worthy of it. Ladybug not returning Chat Noir's feelings is treated as proof that she doesn't have to.
  • Entertainingly Wrong: Or 'Frustratingly', rather: Bustier sincerely thinks that Marinette is suffering in Mendeleiev's class, spending much of her POV section mentally lamenting about how she used to be one of the 'best examples' she had for Chloe (read: Bustier pressured her into being a Stepford Smiler who endured Chloe's bullying rather than 'rocking the boat' by asserting herself). The notion that Mendeleiev might be better for her by virtue of actually stepping in is completely lost upon her.
  • Entitled Bastard: Plenty of examples can be found in Bustier's class:
    • Chloe feels entitled to having her favorite victim to push around, actively seeking her out and getting pissed off when others get in her way.
    • Adrien feels entitled to Ladybug, believing that their Miraculouses are proof that they're 'destined' for each other. He ends up stringing Aurore along when he thinks that she holds the key to Ladybug's identity, and spends a lot of time downplaying and brushing off Ladybug's disinterest, even telling her to her face that "We are going to be a thing one day, you know."
    • Alya feels entitled to Ladybug's identity despite repeatedly being warned off, until Nadja's disastrous interview combined with Marinette telling her off leads to her recanting and deleting the Ladyblog. Even then, she tells Marinette that she suspected she was Ladybug and seems to hope for some kind of confirmation.
    • At one point, Marinette is just passing by Bustier's classroom when Nino grabs her arm and hauls her in, offering her up to help with a group project. Despite her pointing out that she never agreed, they brush off her complaints and act as though she should be happy to help.
  • Flanderization: Adrien is just a mess of negative character traits without the positive ones he has in Canon.
  • For Want of a Nail: What if Marinette was placed into Mendeleiev's class instead of Bustier's?
    • While Marinette is still caught in the rain after their third day at school, Adrien doesn't offer her any help, only an apologetic smile as he opens his umbrella and hurries off. It's Aurore who offers her help instead, walking her home despite the inconvenience to herself.
    • Since they aren't friends, Ladybug sees Alya as reckless and a potential threat to her Secret Identity, repeatedly warning her off and stating on Face to Face that she doesn't support the Ladyblog.
    • Marinette does not develop a crush on Adrien. In fact, she barely knows who he is until Aurore points him out.
    • Chloe is the reason Aurore loses the Weather Girl competition.
  • Heartbreak and Ice Cream: After the Stormy Weather incident, Marinette takes Aurore back to the bakery to binge on cookies and watch movies together up in her room.
  • Heroic Bystander: When Despair Bear attacks Chloe and Amber's half-birthday party, Amber grabs the akuma outright. Jean trips it up with a card later, and Aurore helps pin it down.
  • Hoist by Her Own Petard: Chloe perfectly recreates Marinette's bowler hat for the contest... including the hidden signature she incorporates into her work, disguised as embroidery. This proves to the judges who the real design thief is, resulting in her disqualification.
  • In Spite of a Nail: Marinette still gets the Ladybug Miraculous, and Adrien still gets the Cat Miraculous.
    • Alya still creates the Ladyblog, and still tries to figure out Ladybug's Secret Identity despite the superheroine being much less tolerant of her antics.
    • Aurore still loses the Weather Girl competition in chapter 5. Why she lost, though, is a different story...
    • Chloe still gets her hands on Marinette's design and enters the hat contest in Chapter 9. Despite her efforts, Marinette still wins.
  • Internal Reveal: Ladybug learns the truth about the Copycat incident when Nadja brings Theo onto her show as a surprise guest in an attempt to ambush her and Chat with 'proof' of their relationship. This does not go over well.
  • Laser-Guided Karma:
    • After rigging the Weather Girl contest, Chloe gloats to Aurore about it, rubbing it in her face... and triggering the birth of Stormy Weather.
    • When Chloe is caught cheating in the hat-making contest, she's not only disqualified, but banned from entering any further fashion competitions. By her own mother.
    • Chat Noir lying to Ladybug and making her think she was responsible for Theo becoming Copycat blows up in his face after she finds out what really happened.
    • Nadja also finds herself facing considerable backlash when her tactics on Face to Face lead to her losing her 'exclusive interview' and getting into serious trouble with her boss.
    • Alya also faces fallout from that interview courtesy of Nadja bringing up the Ladyblog only for Ladyblog to declare that she doesn't support it, specifically pointing out the importance of keeping their secret identities secret. This causes the blog to get some backlash until she deletes it.
  • Outof Character: Chat Noir's flaws become so exaggerated that they're his only qualities.
  • Oblivious to Love: Adrien doesn't seem to notice the huge crush Aurore has on him. Even when she drops hints via the pastries she brings to him or flat out tells him to his face. His reaction? He asks her for her name.
  • Polar Opposite Twins: Chloe and Amber; Chloe's a Spoiled Brat who expects everything to go her way, while Amber is much nicer and regards Marinette as a Worthy Opponent and potential rival.
  • Pungeon Master: Aurore tends to pepper everything she says with weather-puns.
  • Revenge Fic: This was basically written to bash Adrien. At no point does the author make any attempt to "redeem" him. Instead focusing on why Marinette is so much better.
  • Ronthe Death Eater: Adrien is a naive but we'll meaning boy in Canon that protects Ladybug by TakingtheBullet. Here, his flaws are his only personality traits.
  • Screw the Rules, I Have Connections!: Chloe's so used to this working in her favor that she's caught completely off guard when Mendeleiev doesn't back down. She also rigs the Weather Girl contest against Aurore in order to 'punish' her for standing up to her and defending Marinette, and is utterly aghast when Audrey reacts to her cheating in the hat-making contest by disqualifying and banning her from future competitions.
  • Screw This, I'm Outta Here!: Ladybug storms out of the Face to Face interview after Theo's brought in.
  • Shut Up, Hannibal!: When Adrien attempts to lecture Aurore over 'ruining Chloe's party' by stepping in to stop her bullying, Marinette cuts him off cold.
  • Stern Teacher: Ms. Mendeleiev, naturally.
  • This Is Reality: Part of Ladybug's call-out to Chat after the failed interview:
    Ladybug: "We're not celebrities. We're heroes, Chat. We're not out here saving the day for a big show to please the public; this isn't some big act! This is real! There's a terrorist out there, taking advantage of people, doing some real harm!"
  • What the Hell, Hero?: Ladybug is livid when she learns what really sparked the creation of Copycat, and calls Chat out on lying to her, as well as how he's been brushing off her repeatedly stated disinterest in him and encouraging the speculation over their 'relationship status'.
  • You Can't Fight Fate: Chat Noir is so convinced that the Ladybug and Cat are 'destined partners' that he tells Ladybug flat-out that they're going to be together someday and that she should stop denying it.
