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.
The trope of the Ice Devil Slayer being an outcast, at least initially, is also seen. They might have powers that are feared or misunderstood by others in the guild. This leads to situations where they have to prove themselves. And of course, the trope of a forbidden love interest, perhaps with someone from a different magical background or even an enemy faction, which adds a layer of drama to the story.
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.
One popular trope is the 'power - up' trope. In many fanfictions, characters from both Fairy Tail and Demon Slayer gain new powers or improve their existing ones in unique ways. For example, a fanfiction might have Tanjiro learning some Fairy Tail magic to enhance his demon - slaying abilities. Another common trope is the 'team - up' trope. Fans love to see characters like Natsu and Tanjiro working together against a common foe. It creates a lot of exciting action scenes and interesting character dynamics.
One common trope is the 'fish - out - of - water' scenario. For example, a God Slayer character suddenly finding themselves in Hogwarts or the Fairy Tail guild. Another trope could be the power - up trope. A Harry Potter character might gain God Slayer abilities or Fairy Tail - like magic to become stronger. There's also the team - up trope, where characters from all three universes join forces to take on a powerful enemy.
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.
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.
One common theme is the struggle between good and evil. Since devil slayers are involved, there's always the fight against dark forces. Another theme is friendship, like in Fairy Tail, where the devil slayers form bonds with the guild members.
Gray Fullbuster is a great character to write about. He already has ice - making abilities, so as an Ice Devil Slayer in fanfiction, he could have some really cool power - up scenarios. His brooding nature also gives a lot of room for character development. You could explore his past more deeply and how it relates to his newfound Devil Slayer powers.
One popular trope is the 'gamer in a new world' where the main character, often from our world, gets transported into the Fairy Tail universe and uses their gaming knowledge to their advantage. For example, they might know strategies from RPGs that help them in battles in the Fairy Tail world.
One popular trope is the struggle for power. The necromancer in Fairy Tail fanfiction often has to deal with the power they possess. They might be tempted to use it for wrong reasons like revenge or domination. Another trope is the outcast status. Since necromancy is often seen as a dark art in the Fairy Tail universe, the necromancer character is usually an outcast, shunned by the regular guild members. And then there's the redemption arc. Some fanfictions show the necromancer trying to redeem themselves and use their powers for good, despite the initial negative perception.
Well, she could start off being an outcast in Fairy Tail because her ice powers seem so different from the rest. But then she proves her worth by using her ice dragon slayer magic to save the guild from a powerful water - based enemy. The ice would counter the water and she'd become a hero.
