Well, it could be that the 100 - year quest is a mission she has to complete before her child is born. This could involve searching for a certain magical item or knowledge that will ensure the safety and well - being of her baby. The pregnancy might also be a result of some extraordinary event during the quest, like a magical union with a powerful being. And as the years pass, she has to balance her physical and emotional state as a pregnant woman with the demands of the quest.
The fanfic might focus on the relationships around Lucy during her pregnancy in this 100 - year journey. Her friends or family could be helping her, or there could be some who oppose her due to the special circumstances of her pregnancy. For example, there could be a prophecy related to her unborn child that some want to prevent from coming true. Also, the passage of time during this 100 - year quest could have a profound impact on her pregnancy. She may experience different stages of the pregnancy in different historical or magical periods, which could bring about unique difficulties and growth for her character.
It could be a heroic character she meets during her quest. Maybe a powerful wizard or a brave knight who has a brief but intense encounter with Lucy, leading to her pregnancy.
Well, one possible plot could be about Lucy's journey through her pregnancy. Maybe it focuses on how she prepares for the baby, like decorating the nursery. It could also show her dealing with the physical and emotional changes. For example, she might be excited but also a bit scared at the same time.
The father of the baby could be a major character. He could be a loving partner, or there could be some drama if he's not as committed as Lucy. Her best friend could also be in it. The best friend might be the one she confides in about all her pregnancy fears and joys.
Perhaps a plot twist could be that Lucy discovers she's pregnant but Natsu has lost his memory. He doesn't remember their relationship and is confused by the news. This would create a lot of emotional turmoil for Lucy as she tries to make Natsu remember while also dealing with the physical and mental changes of pregnancy.
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.
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.
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.
Gray could also be a possibility. He and Lucy have a friendly rivalry and there are moments where their relationship could be interpreted as having deeper feelings. It would be an interesting twist if Gray was the father, as it would change the dynamics between him, Natsu, and Lucy in the fanfic.
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.
Well, it could be about a character's journey to find a fallen star, which might be a magical or important object in the story's universe. Maybe there are challenges and adventures along the way, like facing mythical creatures or solving puzzles.
