What are some interesting plot ideas for a 'Harry raised by grandparents fanfic'?

One idea could be that his grandparents, being more experienced in the wizarding world than the Dursleys, start teaching Harry magic early on in a more positive and nurturing way. Maybe they introduce him to family secrets and spells that have been passed down through generations.

One plot idea could be that Harry's grandparents are very strict about magic, so he has to secretly practice. Another could be that they are part of a secret wizarding society that has been in hiding, and Harry discovers their secrets. Or perhaps they have a special connection to Voldemort's past that Harry uncovers.

He might be more old - fashioned in his ways. His grandparents' values would likely have a big influence on him, so he could be more reserved and traditional compared to the Harry we know from the original series.

Well, perhaps in this fanfic, Harry is raised by Voldemort to be his ultimate weapon against the wizarding world. He's trained to be extremely powerful in combat magic. But as he grows, he starts to notice the fear and suffering Voldemort causes. This could lead to an internal struggle within Harry, between his loyalty to the man who raised him and his own sense of right and wrong. Also, there could be a plot where Harry uses his unique position to secretly undermine Voldemort's plans from within his own ranks.

One idea could be that Harry is raised by a group of centaurs. They teach him their wisdom about the stars and nature. He grows up with a deep understanding of the forest and its magic, and when he goes to Hogwarts, he has a different perspective on magic compared to the other students. For example, he might be more in tune with natural magic and have an easier time in Herbology and Care of Magical Creatures classes.

One idea could be that Sirius teaches Harry all about his family's history in a much more in - depth way than Dumbledore ever did. He might show Harry secret passages in the Potter family home. Another plot point could be Harry learning advanced magic earlier under Sirius' tutelage, like Patronus charm at a younger age.

One plot idea could be that Harry discovers unique magical creatures that exist only in space. For example, there could be a species of floating, star - like creatures that can communicate through light pulses. Another idea is that he has to learn to control his magic in zero - gravity, which presents a whole new set of challenges compared to on Earth. Maybe he also forms an alliance with alien races who are also magically inclined and together they fight against a common dark force that threatens both the wizarding world and the galaxies.

Perhaps the monster has a vendetta against certain wizarding families, and as Harry grows up under its care, he is caught in the middle of this conflict. He has to decide whether to side with the monster or try to find a way to reconcile the differences. This could lead to a whole new set of adventures and challenges for Harry.

In such a fanfiction, perhaps the story could show Harry growing up with a different kind of family dynamic. His grandparents might instill in him values that are different from what he would have learned at the Dursleys'. For example, they could be more open about his magical heritage from the start, which would lead to him being more confident in his abilities as he grows. Maybe they would also have their own set of magical friends and connections that would introduce Harry to a different side of the wizarding world earlier.

One idea could be that Fem Harry shows a great aptitude for magic early on, much like her father James. She might have a special bond with James as he trains her privately. Another could be that she faces unique challenges in Hogwarts due to being female in a story where the original Harry was male, like different social interactions.
