Perhaps his grandparents were great adventurers in their time. They could have traveled to far - off magical lands and encountered strange and wonderful things. Their experiences could be passed on to Harry, inspiring him to explore more of the wizarding world and its secrets. They might also have been involved in some great battles in the past, and their war stories could give Harry valuable lessons for his own fight against Voldemort.
They could be very traditional and strict pure - blood wizards. Maybe they were part of some ancient magical order and had high expectations for the Potter family. They might be disappointed in how James and Lily Potter deviated from some of the old ways, but be very proud of Harry when they get to know him.
If Harry Potter meets his grandparents in a fanfic, it could be a life - changing encounter. His grandparents would likely be shocked and overjoyed to see him. They might be able to fill in the gaps in his knowledge about his family history. They could have known some secrets about the prophecy related to Harry and Voldemort that could help him better understand his destiny. They might also be powerful wizards or witches in their own right and offer to train Harry further in magic, especially in areas that Dumbledore or other Hogwarts professors hadn't covered. Their presence could also give Harry a sense of belonging and family that he had been missing all his life.
One interesting 'Harry Potter Grandparents' fanfiction could be one where Harry discovers hidden secrets about his grandparents through a magical diary. It might show his grandparents' adventures at Hogwarts when they were young and how those events shaped the Potter family legacy.
A great fanfic might be 'The Love Story of Harry Potter's Grandparents'. This would focus on their relationship, how they fell in love, and the challenges they faced. It could describe their courtship, the magical dates they had, and how they overcame any differences or obstacles in their relationship.
They could have had adventures in ancient magical ruins. For example, they might have explored a long - lost wizarding temple filled with powerful spells and dangerous traps. They could have fought off dark creatures guarding the secrets within.
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.
At first, it might be a bit awkward as they get to know each other. But then they would grow closer. His grandparents would probably dote on him and Harry would come to rely on their love and support.
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.
He would likely be more confident. Growing up with his grandparents, who presumably love and support him, he wouldn't have the self - doubt that came from living with the Dursleys. He would be more self - assured in his magical abilities from the start.
