The pacing is an important element too. It shouldn't be too rushed when introducing the two different universes and their characters. There should be enough time for the readers to understand how Natsu's presence affects the Naruto world and how Naruto's world impacts Natsu. Also, look for unique twists in the story. Maybe Natsu has a special ability that no one in the Naruto world has seen before, and that becomes a game - changer in battles or relationships.
One great natsu naruto crossover fanfiction is 'Natsu in the Ninja World'. It has an interesting plot where Natsu's fire - based powers create unique interactions in the Naruto universe. The battles are exciting as he teams up with Naruto and the gang against common enemies.
Goku from Dragon Ball Z could be a great crossover character for Natsu. They are both very strong and have a love for fighting. Goku's ki - based attacks and Natsu's fire magic would make for some epic battles. They could also train together and learn from each other's fighting styles. Also, Alucard from Hellsing could be an interesting crossover. His vampiric powers against Natsu's magic would create a very dark and intense story.
One common theme is misunderstanding. Natsu is often misjudged by his friends, leading to a sense of betrayal. For example, his actions might be misinterpreted due to some magic interference or the scheming of a villain.
A fanfiction idea could be that in a crossover, Natsu is tired because he's been on a long - term mission in a different realm. He returns to Fairy Tail not quite himself. The guild members start to worry as he doesn't have his usual energy for pranks or challenges. As the story progresses, he slowly regains his strength through the support of his friends and the familiar environment of the guild, and in the end, he's back to his old self ready for new adventures.
In natsu and dc crossover fanfiction, the cultural differences between the two universes are also interesting. Natsu comes from a world with a different set of values and norms compared to the DC universe. This can lead to some really fun and thought - provoking situations. For instance, Natsu's straightforward and often impulsive nature can be a contrast to the more calculated and rule - bound heroes in DC. Also, the fanfictions often play with the idea of how Natsu's magic would be perceived in a world that is more science - based like DC. It could be seen as something completely new and strange, or maybe even a threat. And then there are the crossovers that explore how Natsu would interact with the various DC villains. His no - nonsense attitude towards evil might make for some unique showdowns.
Love triangles or polyamorous relationships are also common. With the harem aspect, there are often complex relationship dynamics. Different characters in the harem may have different feelings for Natsu, and Natsu may have to navigate through these emotions. This adds a lot of drama and intrigue to the story. In some fanfictions, characters from different franchises in the crossover might also compete for Natsu's affection.
Well, it's quite possible. Fanfiction writers are known for their wild and creative ideas. Since both Naruto and Natsu are from popular anime, some writer might have thought of creating a story where Naruto is somehow related as Natsu's grandfather. But it also depends on how much of the respective anime universes the writer wants to blend and how they would explain such a connection in the story.
Yes, there are likely fanfictions out there with such a concept. Fanfiction platforms are full of creative and often wild ideas. You can check major fanfiction websites like FanFiction.net or Archive of Our Own (AO3). Just search for the relevant tags or keywords to find them.
There's also 'Natsu's False Betrayal: A Crossover'. In this fanfiction, Natsu is framed for a crime he didn't commit, which makes his comrades turn against him. It's an interesting read as it delves into Natsu's emotions during this difficult time. He has to not only prove his innocence but also deal with the new threats that emerge because of the false accusation.
