As mermaids, Adrien's charm might take on a different form. He could use his allure to communicate with sea creatures, which would make him seem more mysterious to Marinette. His personality would be more fluid, just like the water around him. Marinette would likely become more patient. The slow - paced life underwater, compared to the hustle and bustle on land, would teach her to wait for things. For example, waiting for the right moment to approach a shy sea creature or waiting for Adrien to make a move in their relationship. And this new - found patience could also make her more understanding of others.
Adrien as a merman might become more in tune with the natural elements of the ocean. He could be more carefree and wild, as opposed to his somewhat reserved self on land. His love for adventure could be amplified, and he might be bolder in expressing his feelings, especially towards Marinette. Marinette as a mermaid could be more confident. The underwater world gives her a new sense of freedom, and she's less worried about the small things that bothered her on land. She might also be more assertive in her relationship with Adrien.
Adrien might become more protective. Usually, he's carefree to some extent, but with Marinette pregnant, he would be constantly on guard. For instance, he'd be extra vigilant against any potential threats, even the smallest ones. He may also become more serious about his responsibilities as a future father.
After getting married, they would become more open and trusting with each other. Since they know each other's identities as Ladybug and Chat Noir, there would be no more secrets between them. Their relationship would be more stable and they would support each other even more in their daily lives and superhero duties.
In some fanfictions, there could be a curse. For example, Marinette is a mermaid who has been cursed to lose her voice if she doesn't find true love within a certain time. Adrien, a merman, stumbles upon her and tries to help her break the curse. Along the way, they go on adventures, exploring different parts of the underwater world, from hidden caves filled with treasures to dangerous areas where sea monsters lurk.
They would become even closer. Their love would grow deeper as they are about to start a family together. There would be more tender moments between them.
Well, at first, they might be a bit nervous about how the baby will affect their relationship. But as time goes on, they would grow closer. They would have to communicate more about parenting decisions, which would strengthen their bond. Also, seeing each other as parents would add a new dimension of love. For example, Adrien seeing Marinette as the mother of his child would make him cherish her even more, and vice versa.
A great element in such a fanfiction could be the family aspect. Maybe they start thinking about having children. How would they raise their kids? Would their children inherit their superhero powers? And how would they protect their family from the villains in their world? Their friends like Alya and Nino could also play important roles in their married life, perhaps as godparents or just as good friends who are always there to offer advice and support.
Yes, there are plenty. There are fanfictions that focus on their budding romance, like the ones where they go on a cute date or have a heartfelt conversation that deepens their relationship in a sweet and innocent way.
Once upon a time, Marinette and Adrien's big day finally arrived. The city of Paris was adorned with flowers and ribbons. Marinette, in her beautiful white gown, walked down the aisle. Adrien, looking dashing in his suit, had tears of joy in his eyes. Their friends and family watched with love. As they said their vows, the whole place was filled with an air of magic. And then they were pronounced husband and wife, sharing a passionate kiss as confetti rained down on them.
Another reaction could be that Marinette pretends to cooperate with Adrien at first. By doing this, she can buy time and look for an opportunity to escape or get help. She might act as if she is okay with what is happening while secretly planning her next move, like leaving a clue for someone to find her or finding a way to disable Adrien temporarily.
If Adrien and Marinette were akumatized, their relationship would become very strained. As akumatized individuals, they would be full of negative emotions which could cloud their judgment. Adrien, who usually has a soft spot for Marinette, might not recognize her in his akumatized state and could even attack her. Marinette, too, would be in a different mental state and might see Adrien as an enemy, forgetting their previous friendship and any budding romantic feelings.
