There could be such a fanfic out there. However, the world of fanfiction is vast and unregulated. It's possible that it exists on some niche fanfic platforms. But it's also important to note that some fanfics may deviate from the original source material in ways that some fans might not like. So, even if it exists, it might not be to everyone's taste.
A Natsu x Lucy pregnant fanfic could be full of heartwarming moments. Think about Natsu being overprotective of Lucy during her pregnancy. He'd probably be a bit clumsy at first, but his love for her would shine through. And Lucy would be the one trying to keep things in order while also dealing with her hormonal changes. It could also add a new dynamic to the Fairy Tail group as a whole.
A possible plotline in this kind of fanfic could be quite complex. Firstly, there would be the moment of realization for Natsu and Lucy. After that, they would need to consider the practical aspects like where they will live and how they will support the baby. There could be a rift in their friendship group, with some friends being supportive and others being against the idea. As the pregnancy progresses, they might have to deal with health issues related to Lucy or the baby, and all the while, their relationship would be evolving in the face of this major life change.
One plot idea could be that a magic spell goes wrong and Lucy ends up pregnant. Natsu is initially shocked but then quickly embraces the idea of being a father. They then have to deal with the guild's reactions, some of which are positive and some negative.
Yes, there could be fanfics with this theme that are written in a tasteful and appropriate way. For example, some might handle it in a very platonic or alternate universe kind of scenario where the concept is more about the relationship growth and the idea of family in a non - explicit manner.
Well, one possible plot could be that Natsu and Lucy's relationship evolves from friendship to something more romantic. Then, an unexpected pregnancy occurs which throws their lives into chaos. They might have to face the reactions of their friends and deal with their own fears and insecurities about becoming parents.
Their friends would likely be shocked at first. Happy for them, but also a bit worried. Erza, for example, would probably be very protective. She might start giving Lucy all sorts of advice on staying healthy and safe during the pregnancy. Gray might be a bit awkward around the whole situation at first, but would eventually warm up and offer his support in his own way, like helping Natsu with any odd jobs or tasks so he can focus on Lucy.
Some fans would be really excited. They might love the idea of seeing their favorite characters in a more mature and family - oriented situation. It could add a new dimension to the Natsu - Lucy relationship that they've always wanted to see.
The fanfic allows for creativity. Writers can take the basic framework of the Natsu - Lucy relationship and add their own twists. They can introduce new storylines, settings, or even character traits. For instance, a fanfic might place them in a modern - day setting instead of the usual fantasy world, which gives a fresh perspective. Also, the fanfic community for them is quite active, so there are always new stories to discover.
The chemistry between them. In the original series, Natsu and Lucy have a great dynamic. In fanfics, this is often explored more deeply. Their friendship that could potentially turn into something more is a big draw.
