Merman AU. All Ladybug wishes is to have a Chat Noir by her side, but what Marinette finds is that maybe she just needed a more aquatic companion.

Marinette is an ordinary girl in a village, but when her father is held a prisoner in a castle belonging to a gruesome, cat-like monster, she takes his place in exchange for his freedom. Little does she know that this beast is really a kind-hearted prince who was corrupted by an evil spell. Can Marinette restore the kindness in the heart of a beast and discover the prince inside?

For Marinette, her good luck has just run out. For Adrien, things go horribly wrong. In the blink of an eye, everything has changed - his friend Marinette is akumatized, Ladybug is nowhere to be found, and Papillon looms behind it all. The two heroes have to fight for themselves, but it's hard when they're on opposite ends of the battlefield.

In which Chloé Bourgeois is alarmingly talented at creating akumas and Marinette is pushed too far. Cover by the wonderful 'youturntowatchmyback' on tumblr.

The accident, while unintentional, was costly. For her wrong doings against Chloe, Marinette is sent over the wall to die. But instead of death, she winds up in a strange, unnerving world. Good thing she'll have a cat to watch her back in this bizarre place.

Marinette is working as a maid for the Mayor of France to help her realize her dream. Along the way, she makes new friends, an enemy, a new love and other adventures! Enjoy this AU!

The shenanigans of the cat girl and the bug boy, aka the powerswap AU no one asked for but everyone wanted. (Now featuring: episode rewrites!) Cover by hchano on tumblr.

Both Adrien and Marinette have the tendency to cuddle up to others in their sleep, as both Nino and Alya have experienced. So when the opportunities arise, they toss their friends together and let the snuggles commence.

When Marinette is denied entry to a fencing team due to her gender, she finds a way around it by pretending to be her twin brother, Mark. She attends his school in disguise and fences on the team to prove herself. She also meets and befriends Mark's roommate and fencing teammate, Adrien Agreste, and falls into a strangely familiar relationship with him. Based off She's the Man!

When Adrien discovers the scarf from his father was stolen from a classmate, he sets out to find who it was. It wouldn't be so scary if he didn't borrow Hawkmoth's powers to do it, though. A sort-of Fairy Tale AU.

"In another life, another world, another universe, we were always together. Even if we didn't know it," he was a head taller than her and she felt small in his arms, but he knew without a doubt that she was his lady. Even in the darkest of timelines, he'd fall in love with her all over again. Parallel AU.

When Nino runs headlong into the biggest most stressful secret he can imagine he is suddenly thrown into a world of secret identities and superheroes. Now that he knows Ladybug's identity, he's got to do what he can to help her out. (Not Ninette, Alya and Nino are not together. Pre-animan)

Based on the prompt 'Why are you at my doorstep at 3 in the morning' with Adrinette as a ship. Marinette is woken up in the middle of the night and is shocked to find a very disheveled Adrien at her door. Some secrets are revealed and a few bombs dropped. But most importantly, there are lots and lots of cuddles.

Marinette transforms one night to roam around Paris. All she wanted to do was have a bit of fun, but what she wasn't expecting was a leather-clad boy dancing with her until dawn, flirting with her in that cocky way he does and making her wonder about him more than she has before. What she wasn't expecting, was Chat Noir. Basically just Ladynoir cuteness

Marinette decides to audition for a movie about her alter ego. So does Adrien.

Of all the things Marinette had expected to happen. It was not this. Out of everything thing that could have happened when someone spotted Tikki, she hadn't expected her Kwami to MEOW. And she knew there was only one little creature to blame.

The loss of beloved one drives Marinette to depression leaving her all alone to protect the Paris. Kwamis however can't look at it any longer and decide that it is time to find new heroes to fight at Ladybug's side. Will the new relations give back the light on Marinette's horizon or will it all bring only more regrets?

"It's like a Ladybug," she tells him. "A sign of good luck." Her luck couldn't be any worse, he thinks. [Grim Reaper AU, Character Death]

Basically, what would happen of our main characters had some common sense? -Or- How many times should their identities have been revealed? Spoilers for unaired (in English) episodes of Miraculous Ladybug.

Cat Noir is on a late night run about town when he catches sight of a lone ice skater. To his great amazement it's his classmate, Marinette.

In which Marinette ends up having to fight a villain named the Sculptor while out of costume and nearly has her identity found out.

It wasn't an ordinary wound, and Chat could only hope that he could figure out how to fix this bit of unexpected bad luck before it consumed his Lady. (Some mentions of blood).

When Marinette's school decides to have a costume contest, she and Alya dress up as Ladybug and Chat Noir. Little do they know how much they're amusing a certain black cat.

Whatever you do, don't imagine the akuma merging with Adrien's very brain. Don't imagine Chat begging Ladybug for help. Don't imagine Ladybug not using Lucky Charm. And whatever you do, absolutely do not imagine the cataclysm raised to his head.

ONESHOT He only realized who she was when it was too late.

Adrien looked over at the shy girl as she laughed and joked through their classes. Why wasn't she like that with him? Had he done something wrong, did he make her uncomfortable? Did he intimidate her? He wanted to hear her jokes too, he didn't understand what he had done wrong, but he was determined to fix it. He would get to know Marinette better, maybe then she would be at ease.
