In some fanfictions, Lyon and Sherry might have a story where they are training together to improve their magical abilities. Sherry could be having trouble with a particular spell, and Lyon helps her master it, leading to a stronger bond between them. They then use their combined skills to defend the guild from an outside threat.
Some fanfictions depict them as very close friends. They support each other in their magical pursuits. For example, Lyon might encourage Sherry when she is doubting her magical abilities, and Sherry in turn gives Lyon advice on dealing with his past. This friendship is often a source of strength for both of them in the stories.
There could be a storyline where Juvia and Lyon are on a quest to find a rare magical item. Along the way, they encounter various obstacles like dangerous magical beasts and tricky puzzles. This adventure brings them closer as they rely on each other's strengths. Lyon might use his ice - making magic to clear paths while Juvia uses her water magic to protect them from certain attacks.
One plot idea could be Lyon and Meredy going on a mission together to a mysterious, ice - covered land. There, they discover an ancient magic that is linked to both their pasts. Another could be a story where they get accidentally transported to a parallel world where they have to rely on each other to find their way back home. And a third idea is that they start training together and during the training, they realize they have feelings for each other that they didn't expect.
Maybe a plot where Ren gets cursed and Sherry has to find a way to break it. She could search through different magic libraries and consult with other mages in Fairy Tail. During this time, Ren is struggling with the effects of the curse, which could be something like slowly losing his magic power. Their friendship deepens as Sherry is determined to save him, and in the end, she discovers a rare spell that breaks the curse.
One popular theme is Lyon's relationships, like his friendship with other Fairy Tail members or his potential romantic relationships. Another theme could be his growth as a wizard, showing how he overcomes challenges and becomes stronger.
One possible plot could be that Sherry and Ren team up for a difficult mission in the Fairy Tail world. They might face a powerful dark wizard who has the ability to manipulate time. Sherry's magic could be crucial in deciphering the wizard's spells, while Ren uses his combat skills to protect Sherry during the battles. Along the way, they start to understand each other's pasts and form a deep bond.
A great plot idea could be that Lyon and Juvia are forced to go on a pretend date as part of a mission. They start off awkwardly, but as the date progresses, they find themselves actually enjoying each other's company. For instance, they might have to infiltrate an enemy's ball and act like a couple in love to gather information.
One idea could be that Juvia and Lyon are on a joint mission for the guilds. They get trapped in an ancient, enchanted forest. As they try to find their way out, they start to understand each other better. Lyon realizes Juvia's loyalty and strength, and Juvia sees Lyon's determination and skill. This shared experience could lead to a deeper bond between them.
One idea could be a story where Juvia, Lyon, and Gray have to team up to face a powerful dark wizard that is threatening the Fairy Tail guild. They start off with some tension due to their past relationships, especially between Gray and Lyon who have a rivalry, but as they battle, they learn to work together better. Juvia could also be in a position where she has to choose between protecting Gray or following Lyon's more strategic plans, adding an interesting love - triangle - like dynamic to the plot.
One interesting storyline could be a character from our world getting transported into the Fairy Tail kingdom and having to learn magic to survive. They could form unexpected alliances with the guild members and go on adventures together.
