One interesting plot idea could be that the Dark Dragon Slayer has a hidden past related to Laxus. Maybe they were both part of a secret experiment by a dark guild long ago. As the story unfolds, they discover this connection and have to team up against the remnants of that guild who are now after them. Another idea is that the Dark Dragon Slayer initially starts as an enemy to Laxus but then realizes they have a common enemy in a powerful, evil dragon that threatens the Fairy Tail guild. So they put aside their differences to protect the guild and its members.
A plot could involve the Dark Dragon Slayer being able to sense a strange power within Laxus. This power might be something that was implanted in Laxus by a long - lost dragon, and the Dark Dragon Slayer is the only one who can help him control it. In the process, they go on a journey together, facing various challenges and growing closer as friends. They could also encounter other dragon slayers during their travels who either help or hinder their progress.
A great plot idea could be that a powerful dark force is emerging that is draining the energy of all three worlds. The Naruto characters, Fairy Tail wizards, and Dragon Slayers must team up. They start by having a big meeting to share their knowledge and figure out a plan. Along the way, they have to overcome their differences in fighting styles and beliefs.
Another plot could revolve around the origin of Dragon Slayer magic. Maybe a long - lost scroll is found that reveals secrets about how the magic was first created and what its true purpose was. This could lead the Dragon Slayers on a quest to find out more about their powers and their connection to the dragons.
Maybe the fanfiction could focus on a dragon slayer who loses their powers but then discovers a new way to regain them. For example, they might have to go on a spiritual journey and face their inner demons. Along the way, they form new bonds with the members of Fairy Tail, which helps them in their quest.
Well, the Dark Dragon Slayer could use their dark - based dragon powers, like shadow manipulation, and Laxus could combine his lightning powers with it. For example, the Dark Dragon Slayer could create a shadowy vortex, and Laxus could send his lightning through it, intensifying the attack and making it more unpredictable. The combined power would be like a dark lightning storm that could strike enemies from unexpected angles.
A really interesting plot would be if there was a prophecy about Freed and Laxus having to team up to save the Fairy Tail guild from an internal threat. They would have to face their own insecurities and past mistakes while trying to figure out who the traitor in the guild is. Along the way, they would strengthen their bond and prove their loyalty to Fairy Tail.
One interesting plot idea could be that the 5th generation dragon slayer has a unique type of dragon magic that is a combination of different elements. For example, they can control both fire and ice dragon slayer magic at the same time, which makes them a target for both good and bad forces in the Fairy Tail world. Another idea is that this dragon slayer has a connection to an ancient dragon prophecy that no one else is aware of. They have to figure out what their role is in this prophecy while also dealing with the normal challenges of being a dragon slayer in Fairy Tail.
One idea could be an OC Dragon Slayer who has the power of a unique dragon, like a crystal dragon. This slayer could use the dragon's power to create crystal-based attacks. Another idea is an OC who was trained by a dragon in a hidden realm and then enters the Fairy Tail world with a different set of values compared to the regular dragon slayers. Maybe they have a more pacifist view at first but gradually learn to fight when necessary.
Well, you could create an OC dragon slayer who was initially from a different dimension. In this dimension, the rules of dragon slayer magic are a bit different. They come to the Fairy Tail world and have to adapt their magic while also facing the challenges there. Maybe they have a special form of dragon slayer roar that can freeze time for a short period, which would be a really cool and unique ability in the context of Fairy Tail battles.
Well, you could write about a new dragon slayer who has an elemental power that no one has seen before, like the power to manipulate light and shadow as a dragon slayer. This character could start as an outcast but then prove their worth in the Fairy Tail guild by using their unique powers to defeat powerful enemies. They could also have a special bond with a mysterious dragon that no one else is aware of.
One idea could be to explore the backstories of the dragons more in - depth. Maybe show how they came to be involved in the wars in the first place. For example, there could be an ancient prophecy that led to their conflict.
