One interesting idea could be alternative endings for Naruto's story. For example, what if Naruto didn't manage to bring Sasuke back to the village? Another could be exploring different relationships between characters in more depth, like how Hinata and Naruto's relationship might have developed in a different way. And there might be ideas about new jutsu or powers that the characters could have, which would change the whole dynamic of the battles in the Naruto universe.
One interesting storyline could be Sakura going on missions with multiple characters from different villages. For example, she teams up with Rock Lee and Gaara to stop a new threat that endangers all the ninja villages. Their different fighting styles and personalities create a lot of drama and action.
Hinata is a very likely candidate. She has always had strong feelings for Naruto and in a multi - marriage scenario, she could be one of the first to be considered. Sakura could also be a possibility. Despite her initial feelings for Sasuke, in fanfiction, the story could be rewritten so that she realizes her true feelings for Naruto and becomes one of his wives.
One of the most common characters to crossover with Naruto is Saitama from One - Punch Man. Saitama's overpowered nature and Naruto's underdog - turned - hero story can make for some humorous and action - packed crossovers. Another popular character is Kirito from Sword Art Online. His skills in a virtual world can be compared and contrasted with Naruto's real - world ninja skills. And of course, there's also Alucard from Hellsing. His vampire powers and Naruto's ninja powers can lead to some very dark and intense crossovers.
Multi fanfiction is fan - made literature that meshes together different fictional universes. This can include things like having the superheroes from the Marvel Cinematic Universe meet up with the characters from 'The Hunger Games'. Writers of multi fanfiction often do this to create interesting crossovers, explore new character relationships, and have fun with the creative possibilities of combining different fictional elements.
Often, characters from other fan - loved series that are crossed over with Naruto become popular in 'naruto x multi fanfiction'. For example, if there's a crossover with One Piece, Luffy might be a very popular character in this combined fanfiction. His carefree yet determined personality contrasts with Naruto's in interesting ways, making for engaging interactions.
The potential for new story arcs in 'naruto x multi fanfiction' is great. There could be arcs where Naruto teams up with characters from different fictional universes to face a common enemy. This would not only test his skills but also force him to think outside the box and learn new strategies from his new allies.
Power and mastery. Since having multiple kekkei genkai is a rare and powerful thing in the Naruto universe, a common theme is the main character's journey to master these abilities. They face challenges, train hard, and overcome their limits. Another theme is secrecy. Often, the character with multi - kekkei genkai has to keep it a secret to avoid being targeted.
Power - up is a very common theme. Naruto becomes extremely powerful, often to the point of being godlike. Another theme is the exploration of different universes. Since it's a multi - crossover, he gets to interact with different characters and settings from other fictional worlds.
One possible storyline could be Naruto marrying multiple characters from different clans, which would bring about unique cultural fusions within the Hidden Leaf Village. For example, if he marries a character from the Hyuga clan and another from the Inuzuka clan, there could be interesting interactions between the different family traditions and abilities.
