One idea could be Sasuke and Sakura going on a mission together to a far - off land. Along the way, they face various challenges that test their ninja skills and their bond as friends. They might have to rescue a group of villagers from a powerful and evil enemy. This would show their growth as ninjas and how they support each other.
Well, a plot could be that Beastboy and Raven get trapped in a time loop. Each time they repeat the day, they learn something new about each other and their relationship deepens. Or perhaps there's a new villain in town who targets their friendship specifically, forcing them to work together even more closely to defeat the foe. Also, they could discover a secret garden in the middle of the city that only they can enter, and it becomes their special place to unwind and talk about their feelings.
One plot idea could be a female Sasuke who uses her unique skills in a different way than the male Sasuke in the original. For example, she might focus more on diplomatic solutions to problems in the ninja world, using her intelligence and combat skills to broker peace treaties.
A third idea could be a time - travel fanfiction. A character could go back in time to the era of the founders of Hogwarts. They could learn about the origins of the school, the sorting hat, and the different spells that were created back then. It would be a great way to explore the history of the 'Harry Potter' world without any adult elements.
A crossover with a fairy - tale world could be interesting. Picture Daenerys in a world of Snow White and the Seven Dwarfs. She could use her leadership skills to help the oppressed characters in that world. Or a crossover with a world like Narnia, where the 'Game of Thrones' characters have to adapt to the talking animals and the magic of Narnia. They could also bring their own political intrigue and power struggles to this new world.
One idea could be a story where the Powerpuff Girls go on an intergalactic adventure to save the universe from an evil alien force. They could team up with other superheroes from different planets and use their unique powers in creative ways.
How about a story where an unknown enemy creates clones of them? Naruto, Sasuke, and Sakura have to not only fight these clones but also figure out who the enemy is and why they are being targeted. Along the way, they might discover new powers within themselves and also learn more about their relationships with each other.
One plot idea could be that Sasuke is a vampire who has been secretly protecting Sakura from other dark forces in the vampire world. Another could be that Sakura discovers she has a special blood type that is very alluring to vampires, and Sasuke has to fight his instincts to protect her. Maybe they are both turned into vampires and have to navigate their new existence together.
One idea could be a highschool talent show where Sasuke is forced to participate by the school and Sakura helps him overcome his shyness about performing. Another could be a mystery in the highschool where Sasuke and Sakura team up to solve it, like a series of stolen textbooks. Or perhaps a sports competition where Sasuke is on the track team and Sakura is the team's medic, and they develop a deeper bond through the event.
One idea could be that Sasuke and Sakura are in the same college but in different majors. Sasuke is in a more solitary, academic major like theoretical physics, while Sakura is in pre - med. They meet in a general education class and initially clash because of their different personalities. But as they get paired for a group project, they start to understand each other more. Another plot could be that they are both part of a college sports team, say a martial arts club, and they compete for the top position in the club, which leads to a lot of tension and also a budding romance. A third idea is that they are in a college that has a mystery or a curse. Sasuke, with his natural inquisitiveness, and Sakura, with her determination, team up to solve the mystery, and during this process, their relationship deepens.
A possible plot is that the child is born with a unique power that neither Sasuke nor Sakura have. This power could attract the wrong kind of attention, and the child has to learn to control it while also hiding it from those who would misuse it. The story could also involve the child making friends with kids from different ninja clans and trying to bridge the gaps between the clans, just like their parents did in a way. Also, the child might have to deal with the pressure of being the heir to two very powerful ninja legacies.
