Maybe in the fanfiction, they meet by accident in an online chatroom. Lucy is looking for information about a rare spell and Natsu stumbles upon her post. They then start an adventure together in the online realm to find the spell. This could involve them facing various virtual challenges and making new friends along the way.
One interesting plot could be that they meet in a virtual world while on a quest that is only possible online. They have to team up to defeat a digital monster.
In some versions, they could be part of an online guild. Lucy joins the guild and Natsu is one of the senior members. Their first encounter online is a bit rocky as Natsu teases Lucy, but then they gradually realize they make a great team for the guild's missions, which range from solving virtual mysteries to battling other guilds in online tournaments.
Well, clearly Lucy and Natsu are the main characters. Lucy is often depicted as a smart and resourceful character, while Natsu is more of the impulsive and strong - willed one.
Another plot could be centered around their fears and hopes. Lucy might be worried about being a good mother, considering her own upbringing. Natsu, on the other hand, could be full of hope that their child will be as strong as him, but also a bit scared that he won't be a good enough father. He then decides to go on a journey to learn from other dads in the guild.
Well, there are several potential plots for this kind of fanfiction. Maybe Natsu is in an environment where he is constantly bullied and abused, like in a guild where some members are jealous of his power. Lucy, who has a kind heart, decides to take him under her wing. She might teach him self - defense or help him build his self - esteem. Another plot could involve Natsu being abused due to a family secret or a prophecy that makes others target him. Lucy, with her intelligence and courage, tries to rewrite the fate that seems to doom Natsu to abuse. This could involve going on quests to find artifacts or information that can change the situation.
One interesting story could be about their adventures together in a magical realm where they have to overcome challenges while their relationship deepens. Maybe they face a powerful dark wizard and in the process, they discover new aspects of their feelings for each other.
One possible plot could be that Natsu and Lucy meet in a completely new and unexpected place, like a parallel magical world. They have to rely on each other to find their way back home while also uncovering the secrets of this strange new world.
One interesting plotline could be Lucy and Natsu going on a quest to find a lost dragon egg. Along the way, they face many challenges and their bond grows stronger. Another could be Natsu suddenly losing his dragon powers and Lucy having to find a way to get them back, which involves delving into some ancient magic lore.
Lucy could be an ordinary girl who stumbles upon the dragon by accident. Maybe she was just exploring an old forest or a mysterious cave when she came across it.
One possible plot could be that the kidnappers are from a rival guild who want to use Natsu as leverage against Fairy Tail. Gray could then embark on a solo mission to rescue Natsu, facing various traps and enemies along the way. He might have to use his ice - make magic in creative ways to overcome obstacles.
Another scenario might be a situation where Natsu accidentally eats some magic - enhancing food that makes his emotions go wild. Lucy has to figure out how to calm him down and in the process, they realize deeper feelings for each other. For example, Natsu might start uncontrollably shooting fire everywhere, and Lucy uses her whip to lead him to a safe place where she can try to reverse the effect.
One interesting adventure could be when they end up in a parallel dimension. In this new world, they have to figure out how to get back home. Along the way, they meet strange creatures and learn new magic spells that are unique to that dimension.
