In this fanfiction, his grandparents might be described as having a deep connection to the magical land they live in. They could be the keepers of ancient family secrets. Their physical features might be aged but still show signs of the great beauty and strength they had in their youth. And they may be very loving towards Harry, making up for the lost time they could have had with him.
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.
One possibility is that Harry's grandparents help him uncover his family's true history. They could show him old family portraits and explain the relationships and events that led to the present situation. His grandparents may also have a different perspective on the fight against the dark forces. They could advise Harry on how to use his powers more effectively and how to build alliances. And they might even be the ones to finally reveal the full story behind the prophecy related to him.
Maybe Harry will have an emotional reunion. He could finally learn about his family history that his parents might not have had the chance to tell him. His grandparents might share stories about his parents' childhood, which would give Harry a deeper understanding of his family roots.
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.
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.
He's probably shocked at first. Naruto has grown up without his parents, and suddenly having grandparents appear is a huge surprise.
They might be overjoyed. Since Sarada is part of their family, they would likely welcome her with open arms and big smiles. They could be very proud of how far she has come in her ninja training.
His magic could develop in a more secluded and family - centered way. His grandparents might have their own unique magical knowledge, passed down through generations. They could start by teaching Harry basic spells in the privacy of their home, away from the prying eyes of the wizarding world. For example, they might show him how to use magic to tend to their garden, making the plants grow faster and healthier.
One common theme is family discovery. Harry gets to know his family in a way he never could in his own time. Another theme could be time - related challenges. He has to deal with the rules of time travel and not mess up the timeline. For example, he might have to be careful not to introduce future magic that could disrupt the past.
