I really like 'Etherious Natsu's Adventure'. This fanfic takes Natsu on a journey where he has to face some of the darkest secrets of his past as an Etherious. It's well - written with a lot of action and emotional moments. For example, there's a part where Natsu confronts a figure from his forgotten past, and the way it's described is really engaging.
Well, in these fanfictions, the concept of the Etherious is really interesting. It allows for a lot of creative exploration. For instance, we can see different interpretations of how Natsu's Etherious nature affects his relationships with other guild members. Some fanfictions show him having to struggle with his darker side, which makes for a great read. Also, fans love to see Natsu in new and exciting situations that the original series might not have covered, like facing ancient evils related to his Etherious origin.
A theme that is quite prevalent is the idea of sacrifice. In many fanfictions, either Natsu or Lucy is put in a position where they have to sacrifice something for the other. It could be their own safety, their magic, or their dreams. Also, the theme of growth is common. They both grow as characters, learning more about themselves and each other as the story progresses. This growth can be in terms of their magical abilities, but also in their emotional maturity.
One great 'etherious natsu dragneel and lucy fanfiction' is 'A Bond Beyond Magic'. It beautifully explores their relationship in a world where they face new and unexpected magical challenges together. The way it develops their characters and the unique magical situations they encounter make it a very engaging read.
Definitely Zeref. Since he has a connection to the Etherious and also to Natsu in the original Fairy Tail story. Another good character could be Gray Fullbuster. His ice - magic could contrast well with the more chaotic and dark powers of the Etherious. Also, Mavis Vermillion could be included. Her wisdom and powerful magic could play a role in helping Natsu deal with the Etherious side of things.
One idea could be Natsu from Fairy Tail finding himself in a parallel universe where he is an Etherious. He has to deal with the new powers and the darker side of himself while still trying to find his way back home. Another could be an Etherious teaming up with Natsu to fight a common enemy that threatens both their worlds. Maybe a powerful dark mage who wants to use the power of the Etherious and also destroy Fairy Tail.
There could be a mysterious old wizard who takes Natsu under his wing when he leaves Fairy Tail. This wizard might have knowledge of ancient magics that Natsu is eager to learn.
Another interesting plot could be that Natsu leaves Fairy Tail to follow in the footsteps of a long - lost relative who was also a powerful mage but had some sort of connection outside of the guild. Along the way, he meets new allies and enemies, all while the Fairy Tail members are trying to bring him back.
One thing that might make it unique is the combination of different fictional universes. Naruto and Etherious come from very different settings, so the crossover itself is distinct. The character of Dragneel could add another layer of uniqueness if he has a special role or ability in the story.
In the 'etherious naruto dragneel fanfiction', it could be that the author is creating a whole new adventure. Maybe Naruto finds himself in a world full of Etherious and has to team up with Dragneel to face some common enemy. The fanfic could play around with different magic systems from both Naruto's ninja world and the Etherious world. It might also delve into the backstories of the characters to give them more depth and make the story more engaging for readers who are fans of both universes.
