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 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.
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.
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 do a Magi crossover with 'Fairy Tail'. The guild system in Fairy Tail and the different types of magic there could be compared and contrasted with Magi. The characters from both could team up for quests. Or consider a crossover with 'Attack on Titan'. The Titans could be a new threat in the Magi world, and the Survey Corps could use Magi's magic to fight them.
One interesting concept could be the exploration of different magical abilities that the reincarnated OC might possess. In Magi OC Reincarnation Fanfiction, the OC might have unique powers that are different from the existing characters in the original Magi universe. This can lead to new and exciting storylines.
Some Magi Ren OC fanfiction focuses on the relationship between the OC and Ren in a romantic way. The OC could be a healer who patches up Ren after his battles. As they spend more time together, feelings start to develop. It's a sweet and often - explored theme in fanfiction that allows for a lot of character development and exploration of the emotions within the Magi Ren setting.
A hobbit OC fanfic could focus on a young hobbit who dreams of leaving the Shire to become a great warrior. They set out on a journey against the wishes of their family and face many challenges. Along the way, they meet different races like elves and dwarves and learn from them, all while trying to prove themselves in a world that doesn't expect much from hobbits in terms of combat.
One idea could be creating an OC that is a hybrid of different Pokemon types. For example, a Pokemon with the features of a water - type and an electric - type. This could lead to unique abilities and an interesting backstory about how it came to be. Another idea is to have an OC that is a trainer from a far - off, unexplored region. This trainer could have different training methods and a whole new set of Pokemon not commonly seen in the main Pokemon world. You could also make an OC that is a Pokemon with a special power related to emotions, like it can heal other Pokemon's wounds when they are sad or boost their power when they are happy.
An OC in a Grojband fanfic could be a time - traveler from the future. They come back to the present day where Grojband exists and tries to change the course of the band's history. Maybe they know that the band is going to face a big obstacle in the future and they want to prevent it. This OC could introduce futuristic music technology to Grojband, making their music even more extraordinary.
