Well, a great plot could be Hagrid and Harry going on a journey to find out more about Harry's parents. Hagrid, being one of the few people who knew them, could share stories along the way. Also, Hagrid could train Harry in some basic magic skills before he even goes to Hogwarts. This would give Harry an edge and also strengthen their bond. Maybe Hagrid could also introduce Harry to some of his half - giant relatives, which would be a really unique experience for Harry.
One plot idea could be Hagrid teaching Harry all about the magical creatures in more detail. Since Hagrid has a great love for them, he could take Harry on secret trips to see rare ones. Another could be Hagrid helping Harry deal with the Dursleys in a more magical way, like using minor spells to make their lives a bit more difficult when they're mean to Harry. And perhaps Hagrid could be the one to first introduce Harry to the idea of different magical cultures, as he has so many connections in the wizarding world.
A plot where fem Harry discovers a secret about Hagrid's past that is linked to her own family history. This could lead them on a journey to uncover the truth. Along the way, they face various obstacles and enemies who don't want the truth to come out. Through their combined strength and friendship, they strive to reveal the long - hidden secrets.
One idea could be Sirius teaching Harry all the secret passages around Hogwarts that he knew as a student. Another could be Sirius introducing Harry to the wizarding world's underground music scene. Or perhaps Sirius helping Harry deal with his nightmares about Voldemort by sharing his own experiences of facing dark magic.
One plot idea could be Hermione helping Hagrid with a new magical creature he discovers. Maybe it's a creature that has unique abilities and Hermione uses her extensive knowledge from books to figure out how to take care of it.
One idea could be that Harry discovers he has a sister he never knew about. He then has to protect her from the dark forces in the wizarding world while also teaching her about magic. Maybe they go on a journey to find out more about their family's past together.
One idea could be Teddy Lupin having trouble adjusting to Hogwarts due to his unique situation, and Harry helps him navigate the challenges. Harry could share his own experiences of feeling out of place as a young wizard. For example, Teddy might struggle with his Metamorphmagus abilities and Harry, having faced many odd situations himself, gives him advice on how to control it and not let it make him stand out too much in a negative way.
In this fanfiction, a plot could be Teddy getting into trouble with the Ministry of Magic for some accidental magic gone wrong. Harry has to use his influence and experience to get Teddy out of the situation. Along the way, they could bond over their shared experiences of being different in the wizarding world. Harry could also introduce Teddy to his friends from the old days, like Hermione and Ron, and Teddy could learn valuable life lessons from them. This would not only strengthen their relationship but also help Teddy grow as a person and a wizard.
Another idea is that Harry, already being a hero, has to teach his sister all about the wizarding world. He shows her Hogwarts, but they face challenges like some students being jealous of her relation to Harry. They go on adventures in the Forbidden Forest together, and Harry imparts his wisdom and courage to her.
One idea could be Minato teaching Naruto how to master the Rasengan at a very young age. Since Minato was the creator of it, he could pass on his in - depth knowledge. Another plot could be Minato protecting Naruto from the early threats that Naruto faced in the original story, like the Akatsuki's early interest in him. Also, Minato could introduce Naruto to the other powerful ninjas of the Hidden Leaf in a more personal way, which would change Naruto's relationships and his standing in the village.
One plot idea could be that Snape takes Hermione under his wing after he discovers her extraordinary magical potential at a young age. He secretly trains her in advanced potions and dark arts defense, much to the surprise of the other Hogwarts faculty. Another could be that Hermione's parents die unexpectedly, and Snape, having a soft spot for her intelligence, steps in as a guardian. He helps her navigate the complex wizarding world politics while she tries to uphold her muggle - born values.
Another idea is Naruto helping Gaara control his tailed beast better. Naruto, having a tailed beast of his own, could share his techniques and experiences. He might take Gaara to a secluded place where they can practice without any distractions. This would not only strengthen Gaara's control but also deepen their bond as they face similar challenges.
