A plot could involve Voldemort somehow being involved in the body - swap. He wants to use Harry's new form as Lockhart to spread chaos in Hogwarts. Harry has to figure out Voldemort's plan while dealing with the everyday challenges of being in Lockhart's body, like dealing with his adoring fans among the students. He also has to find a way to communicate with his friends about what's really going on without giving away his identity. Maybe he uses some sort of code that only Hermione can decipher.
One plot idea could be that a spell gone wrong during a Defence Against the Dark Arts class causes the body - swap. Harry then has to teach the class while in Lockhart's body. He tries to use his own real - life experiences with dark magic to teach the students, but has to do it in a way that seems like Lockhart's flamboyant style. Another idea is that while in Lockhart's body, Harry discovers a secret diary in Lockhart's office that leads him on a new adventure to solve a mystery at Hogwarts that Lockhart was somehow involved in.
Well, one possibility could be that Harry has to deal with Lockhart's over - the - top self - image while trying to figure out how to get back to his own body. He might struggle with Lockhart's flamboyant mannerisms and all the lies Lockhart has told. For example, he could be forced to attend some of Lockhart's book - signing events and pretend to be him, all the while trying to find a way to reverse the body - swap magic.
If Harry gets put in Lockhart's body in a fanfic, he would face a lot of challenges. His personality is so different from Lockhart's. Harry is more modest and sincere, while Lockhart is all about self - promotion. Harry would have to adapt to Lockhart's mannerisms and speech patterns. He could use this opportunity to learn more about Lockhart's past and why he is the way he is. Maybe he could even find a way to redeem Lockhart in the eyes of the Hogwarts community by doing some good deeds while in his body.
With the other students, Harry in Lockhart's body would be seen in a whole new light. Some students who admired Lockhart might be drawn to him, while others who saw through Lockhart's facade might be even more distrustful. Harry would have to navigate these new social dynamics. His relationship with the teachers would also be strange. They might expect Lockhart - like behavior from him, and Harry would have to balance between acting like Lockhart enough to not arouse suspicion and still being able to pursue his own goals.
One plot idea could be that Naruto is sent on a special mission to a far - off land where MILF - type ninja are the norm. There, he impresses them with his skills and they form a harem around him. Another could be that some kind of magic or curse makes older women in the Leaf Village suddenly become attracted to Naruto, and they start to gather around him.
Sure. Maybe Harry is raised by Tony Stark in particular. Stark tries to understand Harry's magic and even uses some of his technology to enhance Harry's magical items. For example, he modifies Harry's wand to be more powerful. When Harry is old enough, he wants to go to Hogwarts, but the Avengers are hesitant because they don't know what kind of place it is. This creates a conflict. Or perhaps an alien race attacks both the magical world and the Muggle world, and Harry has to bring the two worlds together to fight the common enemy.
One idea could be that it's a magical accident due to a misfired spell. Maybe Harry was trying to help someone with a fertility spell and it backfired on him. Another could be that it's part of some ancient prophecy where a male must carry a child for a great purpose. And perhaps there's a new type of magic that allows male pregnancy and Harry is the first to experience it in the wizarding world.
One possible plot for this fanfic could be that Dumbledore, seeing Lockhart's incompetence, decides to give Harry a chance to teach. Harry, being humble, initially doubts himself but then realizes he has a lot to offer. He starts teaching spells and defensive techniques that he has learned from his own adventures. He also uses his Gryffindor courage to inspire the students, and along the way, he might even discover some new ways to fight the Dark Arts that he hadn't thought of before, all while dealing with the challenges of being in a position of authority at such a young age.
Maybe they get transported to a strange new dimension where the rules of both their worlds are all jumbled up. They have to rely on each other to survive and find their way back home. During this time, they encounter strange creatures that are a mix of magical beasts and Greek monsters. And as they face these challenges, they grow closer as brothers and become even more powerful as individuals.
A possible plot could involve a dark wizard from the Harry Potter world teaming up with a powerful sea - based villain in the ship girl world. Harry has to form an alliance with the ship girls to stop them. Along the way, he discovers that there are hidden magical elements in the ship girl world that are connected to his own magic. He then uses this knowledge to strengthen the bond between him and the ship girls and ultimately defeat the villains.
Perhaps Voldemort discovers Harry's connection to Lady Sif and tries to use it to his advantage. He might try to steal some Asgardian magic or artifacts related to Harry's heritage. Harry then has to stop Voldemort while also dealing with the new - found knowledge of his mother and the Asgardian world.
