Some fanfictions focus on a time - travel storyline. Natsu and Lucy might be sent back in time to an important era in Fairy Tail's history. There, they have to ensure that certain events happen correctly to safeguard the future of the guild. Along the way, they interact with past versions of the guild members and experience things that change their perspective on their own relationship and the guild as a whole.
Another popular one is a time - travel story. Natsu and Lucy get sent back in time and have to figure out how to get back to their own era. Along the way, they meet younger versions of their guild mates and learn more about the history of the guild. Their relationship deepens as they rely on each other to navigate this strange situation.
A common storyline is when Lucy's celestial spirits play a role in bringing Lucy and Natsu closer. For example, one of her spirits could give Natsu a task that involves protecting Lucy at all costs. This leads to them spending more time together and sharing deeper conversations. Another idea is that a powerful enemy targets Lucy specifically because of her connection to the celestial world, and Natsu is determined to keep her safe no matter what. This shows his loyalty and could develop into a more romantic relationship as the story progresses.
One popular theme is their friendship. Many fanfictions explore how their relationship grows from being just guild mates to very close friends. Another theme is adventure. Since they are both members of Fairy Tail, a lot of stories involve them going on quests together, facing powerful enemies and discovering new magic. Also, the theme of loyalty is common. Writers like to show how they are loyal to each other and the guild.
One popular theme is their teamwork. They are often shown working together in battles, combining Natsu's brute strength and Lucy's strategic use of her celestial spirits. Another theme is friendship. Their bond as friends is explored, like how they support each other through tough times in the guild.
A great Natsu and Lucy fanfiction might involve a time - travel plot. For example, they could go back in time to the founding of Fairy Tail. This would give them a chance to meet the original members and change the course of history. Along the way, their relationship would surely evolve as they face the challenges of the past. It's a really cool concept that many fanfiction writers like to explore.
One popular theme is their partnership in battles. They are often depicted as a strong duo, using their respective magics to overcome tough opponents. Another theme is their friendship within the guild. The banter and support they give each other is a common aspect. Also, the theme of them achieving personal growth together, like Natsu learning more about his past while Lucy becomes a stronger Celestial Spirit mage with Natsu's encouragement.
The theme of friendship and family within the guild is also common. Natsu and Lucy are like family to each other in the Fairy Tail family. Fanfictions might show them participating in guild festivals or helping new members feel welcome. Their relationship is part of the warm and inclusive community that Fairy Tail represents, without any inappropriate content.

Fanfictions that involve abuse are not positive or ethical. Fairy Tail is about friendship and positive relationships, so I don't recommend seeking such stories.
