Yes, there might be. The Fairy Tail fandom is large and diverse, and fanfic authors love to explore different relationship dynamics and scenarios. Given the popularity of Laxus and Lucy as characters, it wouldn't be surprising if someone has written a fanfic where they are in a relationship and Lucy becomes pregnant. You could try using search terms related to 'Laxus', 'Lucy', and 'pregnancy' on fanfic search engines to find out.
I'm not sure if there is a specific fanfic with that exact plot. There are a vast number of fanfics out there in the Fairy Tail fandom, but it would take some searching through various fanfic platforms to know for sure. Some popular fanfic sites like Archive of Our Own or FanFiction.net might be good places to start looking if you're interested in such a story.
One great fanfiction could be 'A New Beginning for Laxus and Lucy'. It beautifully portrays their journey into parenthood. The author does an amazing job of showing how they adjust to the idea of having a baby and the changes it brings to their relationship.
A theme could also be the reaction of their friends and the community in the Fairy Tail world. Their friends might be excited, offer help, or there could be some drama if not everyone is supportive. This would add an extra layer of story - telling as they navigate not only their own feelings but also the opinions and actions of those around them.
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.
I'm sorry, I don't have specific 'laxus and lucy pregnant fanfic' to recommend directly. You can try searching on some popular fanfic websites like Archive of Our Own (AO3) or Fanfiction.net. These platforms usually have a large number of fan - created stories and you might be able to find the relevant ones there by using the appropriate search terms.
Finding a particular fanfic about Laxus and Lucy can be a bit of a hunt. Firstly, it's important to note that different fanfic writers have different takes on characters. Some may focus on their individual growth and how they interact within the Fairy Tail guild. You could also join Fairy Tail - related forums or groups on social media and ask for recommendations. That way, other fans might be able to point you in the right direction towards some great Laxus - Lucy fanfics.
Laxus would experience a significant shift in his priorities. His focus would no longer be solely on his own power and status within the guild. Instead, he'd be more concerned about providing a stable and safe environment for his child and Lucy. This might lead to him mending some of his past relationships within the guild. Lucy, on the other hand, would develop a deeper sense of purpose. Her pregnancy would make her realize the importance of family and legacy. She'd start to pass on her knowledge, perhaps about celestial magic, to the unborn child in unique ways, and this would also strengthen her bond with Laxus as they both look forward to the future together.
Well, a possible plot is that there are some dark forces that target Lucy because of her unborn child. Maybe they believe the baby will have some special powers. Laxus then has to go on a journey to find a way to protect them. And as for their relationship, it could be strained at first because of the stress, but they gradually grow closer as they face the challenges together. Plus, there could be a sub - plot about how Lucy's celestial spirits react to the news. Some might be overjoyed and offer their own unique forms of protection.
You can start by looking on Archive of Our Own (AO3). It has a large collection of fanfics from various fandoms. Just type in 'Laxus x Lucy pregnant' in the search bar and see what comes up. Another option is FanFiction.net, which also has a wide range of Fairy Tail fanfics.
There could also be other supporting characters from the Fairy Tail guild. For instance, Mirajane might play a role in giving advice to Lucy about pregnancy and motherhood, since she has a nurturing side. And Makarov, as the guild master, could be involved in ensuring the safety of Lucy and the future of the guild with a new member on the way.
This situation could also bring out a softer side of Laxus that others in the guild haven't seen before. He'll be more affectionate towards Lucy, and they'll share a special bond over their unborn child. Their relationship will transform from just a couple to soon - to - be - parents, which is a huge shift that will be filled with both challenges and beautiful moments.
