For an Aquarius Fairy Tail fanfic, a plot could revolve around her relationship with other Celestial Spirits. Maybe there's a rift between her and some of the spirits because of a misunderstanding. Aquarius is wrongly accused of something she didn't do, like stealing a powerful artifact from the Celestial Spirit World. She has to clear her name while also dealing with the animosity from her fellow spirits. The Fairy Tail guild gets involved to help her out. Lucy, in particular, is determined to prove Aquarius' innocence. As they dig deeper, they find out that there's a much bigger plot at work, a plot that could potentially destroy the balance between the Celestial Spirit World and the human world.
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.
A great plot for an Aquarius Fairy Tail fanfic could be a competition among the Celestial Spirits. Aquarius decides to enter a tournament where Celestial Spirits compete in various magical tasks. She wants to prove that she's more than just a water - based spirit. As she progresses in the tournament, she faces off against some very tough opponents. Meanwhile, the Fairy Tail members are cheering her on from the sidelines. But there are some dark forces at work that are trying to rig the tournament for their own gain. Aquarius has to not only compete but also uncover the conspiracy behind the scenes. This would involve her using her wits and her newfound friendships with the Fairy Tail guild to succeed.
One plot idea could be exploring Aquarius's past more in - depth. Maybe a story where we see her life before she became a Celestial Spirit. Another could be a story where Aquarius has to team up with an unlikely character from Fairy Tail to save the Spirit World.
Well, a plot idea might be that a powerful wizard wants to steal Aquarius' key from Lucy. Lucy has to fight to keep it. Along the way, she discovers that Aquarius has some hidden abilities that she didn't know about before. Another idea is that there is a prophecy about Lucy and Aquarius that they must fulfill together. They initially don't believe it but as events unfold, they realize they have to work as a team to save the world.
One idea could be that Aquarius gets trapped in a different dimension, and Lucy has to go on a dangerous quest to rescue her. She might have to team up with some unexpected allies from Fairy Tail. Another plot could involve Aquarius losing her memory, and Lucy has to help her regain it while also protecting her from those who would take advantage of her in this vulnerable state.
One day in the Fairy Tail guild, Aquarius was feeling particularly moody. She was tired of being summoned just for water - related tasks. So, she decided to go on a little adventure of her own. She left the Celestial Spirit World and entered the human world without being summoned. She wandered around Magnolia, looking at all the strange human things. At first, she was a bit annoyed by the chaos, but then she started to find it interesting. She met some of the Fairy Tail members who were quite shocked to see her. But instead of causing trouble, Aquarius just wanted to explore and maybe find a new purpose beyond just being a tool for water magic.
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.
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.
One possible interesting plot could be that Naruto somehow ends up in the Fairy Tail world. He meets Lucy, who has the Aquarius key. Aquarius initially is distrustful of Naruto but as they face a common enemy, like a dark wizard who is trying to steal all the celestial keys and use them for evil. Naruto's unique jutsu could be combined with Fairy Tail's magic. For example, his shadow clone jutsu could be used in tandem with Lucy's summonings to create a more powerful force against the enemy.
Well, a cool plot for a 'Fairy Tail x Fate fanfic' might be centered around a powerful magical artifact that exists in both universes. The characters from both series start to search for it, and during their journey, they learn about the similarities and differences in their magic systems. Maybe some of the Fairy Tail wizards get mistaken for Servants at first and have to prove their true identity while also dealing with the various factions in the Fate world.
One idea could be that the fallen star is actually a powerful wizard from a different dimension who has lost their powers during the fall. They end up in the Fairy Tail world and have to team up with the guild members to regain their powers and find a way back home. Another plot could involve the fallen star being a magical object that holds a great secret, and Fairy Tail members race against an evil guild to discover and protect it.
One idea could be that your OC is a guardian of a long - lost magical artifact from Fairy Tail's history. They have to protect it from a dark guild that wants to use its power for evil. Maybe they team up with some of the main Fairy Tail characters along the way, like Natsu and Lucy, and there are epic battles to keep the artifact safe.
