One interesting character could be a Devil Slayer who has the power to manipulate shadows. He can use the darkness not only to attack demons but also to move stealthily. His backstory of how he got his powers, perhaps from a fateful encounter with a shadow - based demon, makes him really engaging.
Another common theme is adventure. Combining the worlds of Naruto and Fairy Tail creates a vast new universe full of unexplored places and new threats. So, many fanfictions send the characters on grand adventures in this new world. It usually involves them facing powerful enemies and finding new allies along the way.
One common theme is the struggle between good and evil. Since a fairy represents good and a devil represents evil, their relationship often involves the battle between these two forces within themselves and in their relationship. For example, the fairy may have to question her own values when she falls in love with the devil.
One common theme is power growth. Usually, the water devil slayer starts with a certain level of power and then goes through various challenges and training to become stronger. Another theme is friendship. Since it's set in the Fairy Tail universe, the slayer often forms strong friendships with other guild members. And of course, there's the theme of battling against dark forces. The water devil slayer uses their powers to fight off villains and protect the guild and the innocent.
A common one is a Devil Slayer's journey to redeem themselves. Maybe they were once on the wrong side or made mistakes in the past. Joining Fairy Tail gives them a chance at redemption. They have to prove themselves worthy to the guild members while also using their Devil - Slaying skills to protect the guild from threats that target their new - found family.
A lot of 'Naruto Devil Fairy Tail' fanfictions also play around with the character relationships. You might find stories where the main characters from both series become friends and have to face a common enemy. Some fanfictions also explore the idea of romance between characters from the two different universes, which can be quite creative and engaging.
One popular trope is the struggle between the Ice Devil Slayer's powers and their own humanity. Since they deal with ice - based magic, often there's a battle against the coldness within themselves. Another is the mentorship or rivalry with other Fairy Tail members. For example, they might learn from an older wizard or compete with a fellow guildmate in terms of power and skill development.
One reason is the opportunity for character crossovers. Picture Naruto and Natsu from Fairy Tail teaming up against a Devil from Devil Slayer. It's really exciting! Moreover, the different settings of the three series are very distinct. The shinobi villages in Naruto, the magic guilds in Fairy Tail and the world of Devil Slayer all provide rich backdrops. When these are combined in fanfiction, it creates a complex and interesting universe that draws in fans who are eager to explore new interpretations and storylines.
Well, 'Eternal Love of Fairy and Devil' is quite a good one too. It not only focuses on their love but also on the power struggles in their worlds. The author creates a vivid setting where the fairy's purity and the devil's darkness are in contrast yet also attract each other. Their love is like a bright light in the midst of the chaos of their two worlds.
One popular 'Water Devil Slayer' Fairy Tail fanfiction is 'The Water Devil's Legacy'. It delves deep into the backstory of a water devil slayer character, exploring their powers and how they came to be. Another one could be 'Water Devil Slayer: Ascension' which focuses on the character's journey to master their abilities and their interactions with other Fairy Tail members. There's also 'A Water Devil Slayer's Quest' which has an interesting plot about the slayer going on a quest to find a lost water - related magic item.
