In the fanfic, the Magi Storm might be a test sent by the magical universe. Hermione, being the intelligent and brave character she is, is chosen to face it with Athena as her unexpected ally. The storm could have unique magical creatures that are only visible during such events. Hermione and Athena could form a bond with one of these creatures, like a flying phoenix - like being, which then aids them in their quest to survive the storm and emerge stronger.
A possible plot could be that Hermione is magically transported into a world where Athena exists. A Magi Storm then starts to brew. Athena, recognizing Hermione's potential, decides to help her. They start by seeking shelter in an ancient magical temple within the storm. Here, they discover hidden magic artifacts that hold the key to stopping the storm.
One idea could be a fanfic where the main characters from Magi are transported to a modern-day world. They would have to adapt to new technologies and cultures while still maintaining their magical abilities. For example, Alibaba could use his swordsmanship in a modern-day martial arts tournament. Another idea is a prequel fanfic that explores the backstories of the different djinns and how they came to be in the Magi world. It could also show the relationships between the djinns and the first magi who summoned them.
A plot could revolve around a mortal who prays to both Ares and Athena simultaneously. The two gods are intrigued and descend to the mortal world. There, they find that the mortal's problem is a complex one that requires both war - like strategy and wisdom to solve. As they work together, they discover new aspects of each other and their relationship evolves.
One idea could be a story where Klavier and Athena work together on a complex case. They start off with different perspectives but gradually learn from each other and form a strong bond. Klavier's cool and collected nature contrasts with Athena's more emotional and empathetic approach, which makes for an interesting dynamic.
A cool concept could be a group of gamers who form a guild in the Magi world. They start off as underdogs but gradually rise in power by using their creativity and out - of - the - box thinking that comes from their gaming experiences. They could introduce new forms of magic or combat techniques inspired by games they've played.
One idea could be a crossover with 'Fairy Tail'. The powerful magic in 'Fairy Tail' and the unique magic system in Magi could create really cool battles and interactions. For example, the mages from 'Fairy Tail' could team up with the Magi characters to fight a common enemy like an ancient evil djinn. Another idea is a crossover with 'Naruto'. The shinobi skills in 'Naruto' and the magic in Magi could be combined in interesting ways. Maybe a Magi character could learn some ninja techniques or vice versa. And a crossover with 'One Piece' would also be great. The Straw Hat Pirates could visit the world of Magi and get involved in the search for dungeons and treasures there.
You could make an OC that is a lost heir to a great Magi kingdom. This OC has been raised in obscurity but discovers their true heritage. Their journey could involve learning about the politics, magic, and culture of the Magi kingdom they are heir to. They might face opposition from those who don't want them to claim the throne. You could also focus on an OC who is a nomadic mage, traveling from one place to another in the Magi world, collecting different types of magic and having various encounters with other mages, djinns, and characters from the original Magi story.
One idea could be an SI (Self - Insert) character who has a special power related to water in the Magi world. They could use this power to help their favorite characters during a difficult battle. For example, creating water barriers or using water to heal wounds.
In a fanfic, they could meet in a hotel lobby. Hermione is there for a wizarding conference, and Tom, who has some ulterior motives, strikes up a conversation with her. As they interact more, they find themselves drawn to each other's intelligence, despite their different outlooks on magic.
One idea could be that Hermione accidentally drinks a love potion meant for someone else. This could lead to all sorts of comical and chaotic situations as she starts acting out of character. For example, she might start chasing after a character she normally has no romantic interest in, like Crabbe or Goyle. It could also create a conflict if she's already in a relationship, say with Ron, and he has to figure out how to reverse the effects.
