Another plot could revolve around a competition among different guilds to see who has the best guild master. The Fairy Tail guild master has to prove their leadership skills, strategic thinking in battles, and ability to bring out the best in their members. This could involve various challenges like magic duels, treasure hunts, and solving mysteries.
A more emotional plot could be about the guild master losing their memory. The members of Fairy Tail have to help the guild master regain their memories while also protecting the guild from external threats. The guild master starts to learn about themselves and their relationships with the members all over again, leading to some heart - warming and character - developing moments.
In a fanfic, the Thief's Guild could be a secret organization in the Naruto world that has been stealing ninjutsu secrets for years. One day, they target a Fairy Tail - like magic that has been sealed in the Naruto world. This attracts the attention of Fairy Tail wizards who come to the Naruto world to stop them. Meanwhile, Naruto and his comrades get caught in the middle and have to decide which side to support or if they can find a way to make peace between the two parties.
In a 'Fairy Tail New Guild Fanfiction', you could have a plot where the new guild is formed from the remnants of the old Fairy Tail guild after a great war. The members are trying to rebuild and regain their former glory. However, they face many difficulties such as lack of resources and being shunned by other guilds. As they struggle, they come across a young wizard with extraordinary potential. They take this wizard under their wing and train them. This young wizard then becomes the key to helping the new guild overcome their problems and rise to new heights. The story could also include the relationships between the new and old members, how they adjust to each other, and the growth of the guild as a whole.
One idea could be Natsu leading a special mission within the guild that no one else has been able to complete. Maybe it involves a powerful dark magic that only his alpha - like determination can overcome.
One possible interesting plot could be Naruto, as the guild master, having to deal with a powerful dark guild that is threatening the safety of Fairy Tail. He could use his ninja skills and leadership to gather the members and come up with a unique battle strategy.
You could make an OC guild that is a rival to Fairy Tail at first but then has to team up with them to face a common enemy. The OC in this guild might have a grudge against Fairy Tail initially because of a misunderstanding. For instance, they think Fairy Tail stole a powerful magic artifact from their guild long ago. But as they work together, they realize that they were wrong and form strong bonds with the Fairy Tail members.
A powerful dark wizard who was once a member of Fairy Tail but was banished for using forbidden magic could be a great antagonist. They hold a grudge against the guild and especially the guild master for their expulsion and now seek revenge by trying to destroy the guild from within.
One plot idea could be Aquarius getting lost in the human world. She accidentally gets separated from the Celestial Spirit World and has to find her way back. Along the way, she teams up with some of the Fairy Tail members who are initially skeptical of her but then realize she's not as bad as they thought. Another idea is that Aquarius discovers a hidden power within herself that she didn't know she had. This power could be related to a long - lost magic that was once prevalent in the Celestial Spirit World. It could put her in danger as there are forces that want to control this power.
One idea could be Natsu going on a solo mission to a far - off land that has a different type of magic entirely. He has to learn to adapt and control this new magic to complete his task. Another could be Natsu training a new generation of Fairy Tail wizards, passing on his unique brand of magic and combat skills.
Well, you could write a 'a fairy'a tail fanfic' about a time - travel adventure. Maybe the characters go back in time to prevent a great disaster that was hinted at in the original series. Or perhaps a story where the Fairy Tail guild has to team up with their arch - enemies to face a common, much greater threat. And a simple but interesting idea could be a day - in - the - life story of one of the guild members, showing their normal routine as well as some unexpected events.
You could write a 'Fairy Tail Fanfic' where the magic system is completely different. For example, instead of having different types of elemental and non - elemental magic, there's only one type of magic but different levels of mastery. Or a fanfic that focuses on the relationships between the guild members in a romantic aspect. Like a love triangle between Gray, Juvia, and a new character.
