Well, in such a fanfiction, Natsu might first go into denial about Lucy's death. But as the reality sinks in, he gets drunk. He may end up in a bar frequented by wizards. While drunk, he could get into fights with other wizards who accidentally say something that reminds him of Lucy. His drinking could lead to him losing control of his magic in a dangerous way.
One possible plot could be that Natsu is completely devastated by Lucy's death. He turns to alcohol as a way to numb the pain. His friends might try to reach out to him, but he pushes them away in his grief. He could start having flashbacks of their adventures together while drunk, which makes his pain even more intense.
In this fanfiction scenario, Natsu's world shatters when Lucy dies. He starts drinking heavily. As he gets drunk, he might wander around Magnolia aimlessly. He might visit all the places that were special to him and Lucy, like the park where they often sat or the guild hall. His drunken state could also attract the attention of some dark forces that see his vulnerability as an opportunity to attack, but he is so consumed by grief and alcohol that he doesn't notice the danger at first.
His friends would be very concerned. Gray, for example, might try to physically stop Natsu from drinking more. Erza would likely be more gentle and try to talk to him, to make him understand that getting drunk won't bring Lucy back.
Well, a plot could involve Natsu and Lucy trying to keep the pregnancy a secret at first. They don't want to cause a stir in the guild right away. As the pregnancy progresses, they start to realize they need to prepare. Natsu tries to earn extra money by taking on dangerous jobs, which Lucy doesn't like. Meanwhile, the baby could have some sort of special magic that starts to show even before it's born, attracting the wrong kind of attention from dark mages.
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.
Yes, there are likely fanfictions with such a plot. Fanfiction often explores different scenarios and relationships within the 'Fairy Tail' universe. However, not all of them are well - written or in line with the original spirit of the series.
In many fanfictions, Natsu might get jealous of Lucy when she spends time with other characters. For example, if Lucy is training with Gray more often, Natsu could feel left out and jealous. His jealousy might stem from his deep bond with Lucy, which he may not fully understand himself.
Lucy might be heartbroken. After all, Team Natsu was like a family to her. She could initially go into a state of shock and disbelief. Maybe she would try to plead with the team to let her back in, explaining that whatever they thought she did was a misunderstanding.
Well, it could start with Natsu and Lucy realizing what has happened. Natsu, being his impulsive self, might have some wild ideas about how to handle it. But as time goes on, he would start to understand the seriousness. Lucy would likely be the more practical one, thinking about things like preparing for the baby's arrival. Their relationship could become strained as they deal with the unexpected situation, but also grow stronger as they face it together.
Well, it could completely change the dynamic of their relationship. Firstly, they would have to deal with the responsibilities of impending parenthood. Natsu, being his impulsive self, might have to become more responsible. Lucy, on the other hand, would probably be more cautious about her actions as she has a life growing inside her. This event could also change their relationships with their friends in the guild. Their friends would likely rally around them, but there could also be some who might be shocked or even a bit envious. It could also lead to new story arcs, like how they prepare for the baby, finding a safe place to raise it, and what kind of parents they would be.
Well, at first, they might be a bit scared and it could put some strain on their relationship. But as they come to terms with it, they would grow closer. Natsu would be more protective of Lucy, and Lucy would be more patient with Natsu's sometimes reckless behavior. They would start to plan their future together, thinking about things like where they will live and how they will raise their child. Their relationship would transform from a more carefree one to a family - centered relationship.
Well, in many such fanfictions, it often involves Natsu and Lucy having a special connection related to dragons. Maybe Natsu's dragon powers play a role in bringing them closer in a romantic or fated - mates - like way. For example, they might go on adventures together where Natsu's dragon instincts protect Lucy in a more profound way than in the original story, and their relationship deepens as they face various challenges side by side.
