One way to develop the Nalu child is through their experiences. For example, if they go on a solo adventure and face challenges alone, it can build their independence and confidence. They might learn to rely on their own instincts and magic skills. Their values can also be a key factor. If they value fairness and justice like Lucy, but also have Natsu's sense of loyalty to the guild, these values can drive their actions. Additionally, their appearance can give hints to their character. If they have Natsu's spiky hair but Lucy's eyes, it could symbolize a blend of their parents' personalities, and this can be explored further in how they act and interact with others.
The future child's character can be developed by showing their struggle to live up to their parents' reputations. Since Natsu and Lucy are well - known in the Fairy Tail world, the child might feel pressured. This internal conflict can shape their personality. For example, they could be initially shy but gradually become more confident as they prove themselves.
One popular theme is the adventures of Natsu and Lucy's child. It could be about them discovering their own magic powers, just like their parents did. For example, they might embark on a quest to find a lost magical artifact. Another theme could be the child's relationships with the other members of Fairy Tail. They could form strong bonds with characters like Gray or Erza, learning valuable lessons from them. Also, a theme could revolve around the child facing a new and powerful enemy that threatens Fairy Tail, and having to rise up to the challenge using their unique skills and the support of their family and friends in the guild.
For Natsu, if genderbended into a girl, she might have long pink hair that she ties up in a ponytail while fighting. Her clothes could be a more form - fitting version of the normal Natsu outfit, with a shorter skirt perhaps. She would still have the same fiery spirit, but it might be expressed in a more feminine way, like being more passionate about protecting her friends. As for Lucy, if she were a boy, he might have shorter blonde hair and a more muscular build. His outfits could be more like a male adventurer's, with a vest over a shirt and pants. His key holders would be more like a belt or a bandolier across his chest.
Perhaps the future child is born with a special mission. In the fanfiction, it could be that the child has to reunite different factions of the Fairy Tail guild that have split apart in the future. This would involve the child using their knowledge of their parents' friendship and the power of Fairy Tail's bonds. Also, the future child might face an enemy that is related to an old foe of Fairy Tail, and they need to draw on their family's legacy to defeat it.
These fanfictions contribute to the Nalu ship by giving fans more content. They allow for different scenarios and interpretations of Natsu and Lucy's relationship. For example, a fanfiction might show a side of their relationship that wasn't explored in the original series, like a more romantic or domestic side. This makes fans more invested in the Nalu ship.
They could have flashbacks during the wedding planning of all the times they've saved each other. This would deepen their connection and show how far they've come. For example, when Natsu saved Lucy from the Phantom Lord attack.
To develop Lucy's child character, start with their magic. If they inherit celestial spirit magic, show how they learn to summon and communicate with the spirits. Also, consider their personality. They could be brave like Natsu, or more calm and collected like Gray. Their relationships are important too. How they interact with the older Fairy Tail members can shape their character. For example, if they look up to Erza, they might learn about discipline from her.
The mermaid elements can add a sense of wonder to their relationship. For example, if they are exploring an underwater mermaid kingdom together, it creates a unique and romantic setting. The mermaids' magic or their way of life might also be something that Natsu and Lucy bond over. Maybe they have to protect the mermaids, and this shared goal brings them closer.
They can develop through facing challenges. For example, if they encounter a powerful dark mage, they will have to learn new spells and strategies to defeat the enemy, which will make them stronger.
One great Fairy Tail Nalu highschool fanfiction is 'High School Days with Nalu'. It beautifully portrays their relationship in a high school setting, with lots of cute and fluffy moments between Natsu and Lucy.
