One interesting crossover could be a story where Naruto's ninja skills are combined with Fairy Tail's magic system. Lucy could use her celestial spirit powers along with Naruto's shadow clone jutsu for a unique battle strategy. As for Lemon, perhaps she could be a new character introduced in this crossover world with some special abilities that interact with both Naruto and Fairy Tail elements.
Naruto would likely be curious about the magic in the Fairy Tail world. He might see Lucy's celestial spirit magic as similar to his own summoning jutsu in a way. As for Lemon, if she has a friendly personality, Naruto would probably befriend her quickly. Fairy Tail characters, on the other hand, would be intrigued by Naruto's ninja abilities. They might ask him to show off some of his cool jutsus. Lucy could potentially teach Naruto about the different types of magic in Fairy Tail, while Lemon could offer her own unique perspective on things.
Naruto would probably be very enthusiastic and friendly towards Lucy right away. He might be curious about her celestial spirit keys and ask a lot of questions. Lucy, on the other hand, might be a bit more cautious at first but would be drawn to Naruto's positive energy.
Gray could be another great pairing. The contrast between his cool - headedness and Lucy's more emotional nature could create interesting storylines. For instance, they might be forced to work together on a mission where their differences initially cause problems but later lead to a stronger bond.
One popular theme could be friendship. In Fairy Tail, friendship is a strong element, and in Lucy - centered fanfictions, it might show how her friendships, especially with characters like Natsu, develop in new and interesting ways. For example, they could go on a different kind of adventure together that wasn't in the original series.
Yes, there are some out there. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. However, the 'lemon' aspect might make it a bit more difficult to find as some sites have restrictions on explicit content. You may need to search specifically for 'Fairy Tail Lucy x Sting romance' if you don't want the more adult - themed stories.
If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.
A good one often has well - developed characters. It should stay true to the personalities of Lucy and Gray from the original 'Fairy Tail' series. Their relationship should be built up gradually, with believable interactions and chemistry.
There could also be a plotline where they both discover a new magic together. While exploring this new magic, they have to train closely and that physical and mental closeness could spark a romantic relationship. Maybe it's a long - lost ice - and - celestial - combined magic that only they can master, and as they figure it out, their relationship evolves.
One interesting plotline could be a magic - based adventure where Erza and Lucy team up against a powerful dark mage. They might use their unique magical abilities in tandem, like Erza's requip magic and Lucy's celestial spirit magic to overcome challenges. For example, they could be on a quest to retrieve a powerful magical artifact that has been stolen by the dark mage. Along the way, they strengthen their friendship and learn new magical techniques from each other.
