The baby can introduce a new emotional aspect. The characters in Fairy Tail are known for their strong emotions, and the presence of a helpless baby can bring out their protective and nurturing sides, changing their relationships with each other.
It could be a catalyst for a new adventure. For example, if the baby has a special mark, it might lead the guild to search for the origin of that mark. This could involve traveling to new places, facing new enemies, and uncovering secrets about the Fairy Tail world that were previously unknown. The baby is like a key that unlocks a whole new part of the story.
One possibility is that the baby could be a key to a long - forgotten prophecy in the Fairy Tail universe. Maybe it has special powers that the villains in the fanfiction are after, and the Fairy Tail guild has to protect it.
It can add new plot elements. For instance, Envy's presence might introduce new conflicts that the Fairy Tail characters have to face. This could change the direction of some story arcs in the original Fairy Tail.
The OC's reincarnation can have a huge impact. If they are reincarnated as a new member, they can bring fresh perspectives to the relationships. For example, they might befriend characters who were previously on the outskirts of the guild. If reincarnated as an existing character's relative, it can strengthen or complicate family - like relationships. They could also introduce new rivalries if they have different beliefs or goals compared to other members.
First, know the characters of Fairy Tail well. Their personalities should shine through even when dealing with a baby. For example, Gray's cool - headedness and Erza's strong leadership. Second, create an interesting backstory for the baby. Maybe it's from a lost civilization or has a special connection to one of the main characters. Third, add some action and adventure. Don't just focus on the baby being cute, but also on how it changes the world of Fairy Tail.
It can make readers view their relationship as more complex. The fanfiction might show hidden insecurities or past traumas that were not explored much in the original. For example, if the fanfic focuses on Levy's regret about not being more open with Gajeel, it makes their relationship seem less straightforward and more nuanced.
It can also have a big impact on the characters. For those who have been directly affected by Acnologia's actions, like the dragon slayers who have a special connection to dragons and thus to Acnologia, his death can be a very emotional moment. They might struggle with mixed feelings of relief and guilt. Relief that the threat is over, but guilt because they may feel they could have done more or differently. This internal conflict can be explored in the fanfiction and add depth to their characters.
Their relationship can become more nurturing. Natsu, who is usually brash and impulsive, might become more gentle and protective around the baby. Lucy, on the other hand, would be the more practical one, making sure the baby has everything it needs. This would make Natsu see Lucy in a new light, as a motherly figure, and he would respect her even more. Their love for each other could also deepen as they share the joys and challenges of raising a baby.
In many fanfictions, when Wendy is hurt, it unites the Fairy Tail guild. For example, they might all come together to find a cure if she's been poisoned or injured by a special magic. Her hurt makes everyone more determined to protect each other.
Characters in 'Fairy Tail' fanfiction with 'not normal magic' often have to face new challenges related to that magic. They might struggle to control it at first, like if it's a very volatile form of magic. This internal struggle can be a major part of their character arc. And if the magic is something that society in the 'Fairy Tail' world doesn't understand or fears, they could face discrimination or be hunted, which further complicates their story.
He could be a new addition to the Fairy Tail guild. As a baby, he'd bring a lot of innocence and new energy. The guild members would have to take care of him, like how they take care of each other. Maybe he'd be found near the guild's entrance one day, and they'd decide to keep him. His ninja abilities, even at a baby stage, might start to show in small ways, like his speed or reflexes, which could be interesting to the magic - using guild members.
