AU thinking let's go. Bad boy x sunshine is a classic dynamic and I saw MariClaw (marinette x claw noir) and the possibilities are endless. Since I'm a love square shipper this is going to be MariClaw and Marinette x Emo!Adrien! Highkey I headcanon that Adrien became emo because Marinette did it first so I'm not going to dive into mechanics of why Adrien is emo but Marinette isn't. I would say 'maybe he watched too much anime' but the brand of claw noir feels a bit more more wattpad bad boy (back in 2016) than shoujo bad boy, depending on the shoujo. He's been pining for literal years AU
maybe she once gave him a bandaid, maybe he's always seen her from afar and curiousity became love, who knows! Point is, he's liked her for SO long and when he's given the chance to go to school, he's super excited because that's the school she goes to!! Cue manga cliches and the title is probably something like "The New Delinquent is Actually a Softie at Heart and He's is in Love With Me???" It could be so cliche, with very lighthearted and cute romcom moments. maybe a secret admirer AU!!
It could also be super angst/fluff. Marinette thinks the whole thing is a prank, or doesn't think he actually likes her, and it's the slowest burn or the most comedy romcom. OR it's the first person who appreciates her slash doesnt bully her (the standards are low here, kids, cause i'm going on the assumption she's heavily bullied), and it's a story of self-acceptance! All of these ideas assume that Adrien has the bravery to approach her and talk to her though :> (not quite romantically, thats up to you. Personally, I think he's too shy to be able to blatantly flirt) Integration of Claw Noir is possible is so many ways that I'm not going to go into it. He joined the Supreme to get back at her bullies + protect her AU I once read a villain!chat blanc fic where he and her are soulmates and he does questionable things like follow her around and is kind of wary but also curious. This would have the same vibes! Could also be more wholesome/pining where he stays in the shadows. Plus hurt/comfort when she realizes, plus the fact that his powers are corroding him! Sick fic potential Can also be a lovesquare enemies to lovers (+ mistaken/secret identity), if Ladybug is part of the Resistance and Claw Noir is with the Supreme ;) The Balcony cliche AU
Marinette has mixed feelings on the Supreme but there's one hero who she sees a lot (potential for pining on Claw's part) and it bothers her so much that one day she meets him on the balcony and gives him food and it becomes a Thing! Traditional Marichat vibes but with a more kuu/tsun-dere Noir
Reverse crush AU There's a certain brand of danmei where the MC is really really shy and it's a lot of angst until the ML realizes that the stoic MC is just shy and is actually the cutest, kindest person ever. This! Is! EmoAdrien x Marinette!! One of the potentials, anyway. Marinette thinks Adrien hates her because he keeps glaring/staring at her (and all the stares she's used to are judgemental ones), only talks to her in clipped sentences, and never goes near her. Then, something happens!! Maybe he gives his umbrella to an abandoned cat or something, idk. Point is, she gets more interested and it's a slow burn-ish progressive romance :) Now the above [she thinks he hates her] except he keeps partnering her with projects and events and everything and she's really confused by the mixed signals so can he please stop. I think everyone collectively died when EmoAdrien realized + quietly blushed in the movie so flirting would be SO fun here because both of them would get really embarrassed.
Secret Identity AU Maybe the secret is that he's Claw Noir or the secret is that he's Adrien Agreste but either way it'll be fun :> Maybe she hates his alt persona so he dies a little inside everytime she makes a comment or a jab and this can be either very comedic or very angsty or both Dengeki Daisy AU, same scenario, enough said. Would probably be more interesting if its Claw Noir + OG Adrien / Chat Noir + EmoAdrien, just to have more of a switch. (In Dengeki Daisy, MC has online friend A who she's never met, and a classmate B who she kind of hates. She talks to A about B, where she rants about B and A comforts her. A and B are the same people).
Manhwa style
Sweet, strong, feminine, girlboss MC? With a the stoic, rich, powerful, smitten ML? say less. He might be more of a tsundere than stoic, though. Gabriel Agreste is definitely the hidden boss. Could be the above but also a villainess/reincarnation/transmigation AU. Reincarnated into a game like an RPG or Stardew or something could also be fun, and bonus points if Mari liked him (as a character) before transmigation!
Gaming AU! Gaming AU. Maybe they meet in a game, on Discord, or because they're always playing at the same time and get matched? This is so beautifully canonical. Especially when Adrien is home schooled, he probably gets really attached to his online friend. And if they're both bullied?? they're each other's comfort (be careful to not let this be co-dependent, unless you're going for that). Can have secret identity AU. But, in my personal opinion, the super cute option is to also have them realize on their own! Maybe they've been doing discord calls for ages and recognize each other's voice. Maybe he's been telling her about the school and they realize they're going to attend the same one! Tbh this doesnt have to be mariclaw but the vibes are cute
Extra notes
Yeah Claw Noir doesn't have to have superpowers in all/most of the AUs
Marinette is a loner/bullied in most of these AUs because otherwise it feels a bit too much like a Mary Sue/self-insert (cute competent popular girl meets famous pretty emo boy who hates everyone except her). Can it be done if she's friends with Nino and Alya? Yep. Heavier themes on friendship where Alya (and maybe Nino) are more wary at first but grow to like him and help him be more self-confident. Less romance focus, more character development/trauma healing
If we're going with canon then for all of these, a true happy ending would involve the Supreme being dealt with, but I don't want to deal with that (plus I don't think we know who he is, anyway)
I realize a lot of these are a flavor of Chat Blanc but I had already written it all anyway
Personally, I am a sucker for smitten x insecure and EmoAdrien x OGMari fit that to a tee. Emo x Sunshine I have mixed feelings on because boi have I read a lot of that, but if it's done well it's super cute and MariClaw does that really well!! I could probably think of more AUs but I've already spent at least half an hour purely typing I pretty highly doubt I'll write any of these since they feel like longer fics + I don't have enough canon info on Claw Noir to comfortably characterize him; if anyone wants to write or draw something based on these then feel free to!
