In a fanfiction, Harry as a kid could use magic to swap bodies with his owl, Hedwig. This would lead to all sorts of comical and also dangerous situations. He would have to figure out how to fly and deliver messages while in Hedwig's body, and at the same time, Hedwig (in Harry's body) would be trying to deal with human life at Hogwarts. Another plot could be that Harry uses magic to create a magical bond with the Marauder's Map when he first discovers it. This bond allows him to not only see the map but also communicate with the spirits of the Marauders, who then teach him some unique and powerful spells that are not taught in the regular Hogwarts curriculum.
Well, perhaps Harry uses magic to communicate with the magical creatures around Hogwarts when he's a kid. He might discover a hidden language that only he can understand, and this leads to him making friends with a shy and rare creature that helps him in some future adventures. Also, he could use magic to create a time - loop in a small part of Hogwarts, like the Room of Requirement, where he can practice spells over and over again without anyone knowing, which gives him an edge in his later battles.
One idea could be that Harry, in a moment of desperation during a battle in the wizarding world, pulls out a Muggle gun. This shocks his opponents as they are not used to such weapons.

Maybe he teams up with some Muggle - born wizards who have knowledge of these weapons and they create a new defense strategy for Hogwarts.
Perhaps in a fanfiction, the Minister of Magic is under the influence of a powerful dark charm, and Harry Potter has to find a way to break it without causing chaos in the wizarding world.

This could involve a lot of character development and exploration of the relationships between different wizarding factions.
One idea could be that Harry's kid discovers a hidden magical ability that even Harry doesn't have. For example, the power to communicate with magical creatures in a way that goes beyond normal magic. Another could be that the kid gets into trouble at Hogwarts by accidentally stumbling upon a long - forgotten secret chamber. Maybe it's a place filled with ancient spells and artifacts that are both dangerous and exciting.
Another plot could focus on how the family magic affects relationships. Maybe Harry uses family magic to strengthen his bond with his children in a way that normal magic can't. He could teach them unique family spells that help them understand their heritage better.
Another plot could involve Harry being reincarnated as a different character in the wizarding world. This would give a whole new perspective on the relationships and power dynamics. He could be a Squib who suddenly discovers latent magic within himself in a very different way than before.
