In this fanfiction, Naruto could be cursed with a spell that attracts female characters to him. These female characters include those from different clans and even some who were thought to be dead. He then has to figure out how to break the curse while also dealing with the emotions and dynamics of the harem that has formed around him.
Perhaps Naruto is in a situation where he has to save the lives of several female characters from different villages. As he does so, they develop deep feelings for him and form a harem. This could involve him facing off against new and powerful enemies while also navigating the complex relationships within the harem.
One idea could be Naruto traveling to different dimensions where he meets alternate versions of female characters and they all form a sort of harem around him. Another could be that after a powerful jutsu, Naruto is transported to a realm where the rules of life and death are different, and he has to deal with female characters who have their own motives regarding his presence in this new world.
One plot idea could be that Naruto finds himself in a post - apocalyptic world of Dead Rising. He starts to gather survivors and among them are a group of girls who develop feelings for him. Maybe they have to fight off hordes of zombies together while Naruto tries to keep everyone safe. Another idea is that Naruto has some unique abilities in this new world that draw the attention of different female characters, and they form a harem as they rely on him for survival.
One idea could be a story where characters from 'Dead or Alive' cross over into a post - apocalyptic world. They could use their fighting skills to survive against new and dangerous enemies. Another idea is a crossover with a fantasy realm, and the 'Dead or Alive' characters have to adapt to magic and mythical creatures. For example, Kasumi might learn to use magic spells while still relying on her ninja skills.
Maybe the story could revolve around how Naruto's family being alive affects the political situation in the Hidden Leaf. His father, as a former Hokage, might have different ideas on how to handle relations with other villages. This could lead to new alliances or conflicts, all while Naruto is growing up in a more complete family environment.
A good concept for a Dead or Alive fanfic could be a story centered around a tournament that has some unique rules. Like a tournament where the fighters can only use one special move throughout the entire fight. This would force them to strategize differently. Also, you could write about the friendships and rivalries that develop outside of the fighting arenas among the characters. For instance, how Helena and Christie might become friends despite their different backgrounds.
One interesting plot could be Naruto discovers a forbidden jutsu that allows him to raise the dead accidentally. He then has to deal with the moral implications of bringing back his fallen comrades, like Sasuke's family. Another idea is that the enemies get hold of the same jutsu and raise powerful dead shinobi against the Hidden Leaf.
One idea could be that Naruto and his friends are transported to the world of The Walking Dead. Naruto's ninja skills would be really useful in fighting the walkers. He could use his shadow clone jutsu to distract the walkers while the others look for supplies or a safe place to stay.
One idea could be a crossover where Naruto characters are suddenly thrown into the Highschool of the Dead world. They could use their ninja skills to fight off the zombies. For example, Naruto could use his shadow clones to distract the zombies while others find a safe place. Another plot could involve a Highschool of the Dead character getting ninjutsu powers and having to learn to control them like a Naruto character. Maybe they accidentally use a fire - style jutsu in the middle of the school, causing chaos among the survivors and the zombies.
One idea could be that Naruto, with his ninja skills, gets transported to Starfire's universe. There, his unique abilities draw the attention of many characters, leading to the formation of an accidental harem. For example, his ability to make shadow clones might be seen as a very useful and cool power. Another plot could involve a common enemy that forces Naruto and Starfire, along with other characters who are part of the harem, to work together. This could lead to some interesting dynamics as they all come from different backgrounds and have different ways of fighting.
One idea could be that a Saiyan character somehow ends up in the Naruto universe and due to their unique powers, attracts a harem. For example, they might save a group of ninja from a powerful enemy using their super strength and speed, and the ninja, both male and female, become intrigued by this new and powerful being.
One idea could be that Naruto and Deadpool end up in a strange multiverse situation where they meet various female characters from their respective universes. They then have to team up to protect these females from a common enemy, and in the process, a harem - like dynamic forms as the female characters develop feelings for them.
