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.
Yes, there could be many 'lucy pantherlily' fanfics that focus on other aspects such as their friendship, adventures they go on together, or their character development rather than sex. Fanfic writers often explore a wide range of themes and relationships in their works.
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.
One great 'Charlie Brown and Lucy' fanfic could be one that focuses on their friendship development. It might show Lucy softening her tough exterior towards Charlie Brown. For example, a fanfic could have a scenario where Charlie Brown is having a really bad day and Lucy, instead of her usual teasing, actually offers him some kind of comfort. Maybe she shares her lunch with him when he forgets his at school.
It's highly likely that there exists a fanfic with a Nalu and Lucy pregnancy plot. Given the large number of fanfic writers and the popularity of the Nalu ship, many fans like to create alternate storylines for the characters. Some might be interested in exploring the idea of Lucy becoming pregnant, perhaps dealing with how Natsu and Lucy would handle the situation, their reactions, and how it would affect their relationship and the world of Fairy Tail around them.
There are a lot of fanfics out there, but ones with sexual content are not in line with the general positive spirit of the Fairy Tail franchise. We should look for fanfics that are more about the growth of the characters, their relationships in a non - sexual way, like how Lucy and Natsu support each other during battles and in their quest for magic.
One interesting Lucy fanfic could be about Lucy going on a magical adventure in a new, uncharted land. She might discover new powers or meet unique creatures along the way.
Often, themes of friendship might be common. They could explore how Lucy and Lemon interact as friends, support each other, and have adventures together.
