It could also be in their magical abilities. Suppose the grandfather was really good at a certain type of magic, like transfiguration. Harry might have a natural inclination towards that as well. He could discover that he has an ease with transfiguration spells similar to how his grandfather did, and this similarity could play an important role in the plot of the fanfic.
They might be similar in appearance. For example, they could have the same eye color or the shape of their nose.
It could be an old and powerful wizard who has been in hiding for years. Maybe he was a friend of Dumbledore's but had some differences with him, so he stayed away from the main events in Harry's life until now.
There could also be other characters like Harry's friends, such as Ron and Hermione. They might be involved in the story and notice the similarities between Harry and his grandfather, and through their reactions, the story could unfold in different ways.
Well, perhaps the grandfather could be teaching Harry all kinds of magic that his parents didn't have the chance to. He might introduce Harry to a different side of the wizarding world, full of old family secrets and forgotten spells.
Harry could develop a more unique style of magic. His grandfather might have his own way of doing magic, and Harry would learn from that. For example, his grandfather could be more in tune with nature magic, and Harry would then incorporate that into his spell - casting, making his magic more diverse and less reliant on the traditional Hogwarts curriculum.
One possible plot could be that his grandfather, perhaps a powerful but reclusive wizard, trains Harry in unique magic from a young age. Harry might grow up with a different set of values and skills compared to the original story. He could have a closer bond with the wizarding world's older traditions.
His grandfather could be a very strict and traditional ninja. He might have high standards for Naruto in terms of ninja skills and discipline.
There were a few novels that could be recommended, including How to Stop Death, The Idiot Life from the End of the Marriage, and The Strongest Nanny Dad in the City. The protagonists in these novels lived with their grandfather, and the plots were different. " How to Stop Death " was a fantasy novel about swords and magic. It told the story of a young man who was destined to find his own fate in the process of pursuing justice. " The Idiot's Life from the End of the Marriage " was a light-hearted and funny urban novel. The main character was the second-generation heir, Wang Zhihao. He lived in the countryside with his grandfather, and a series of interesting stories happened. " The City's Strongest Babysitter " was a city-city supernatural novel. The main character was the leader of the Dragon Sect who had become a useless nanny. He and his grandfather had experienced many challenges together. These novels could be used as recommendations for the protagonist and grandfather's life.
The book 'Battle Break's Strongest Villain' met the requirements. The main character, Hun Tianchen, was the young clan leader of the Hun clan. His father was Hun Tiandi. I recommend this book to you, I hope you like this fairy's recommendation, muah ~😗😋
To start a 'Harry Raised Grandfather' fanfic, begin with character development. Figure out what kind of person Harry's grandfather was originally and how Harry's presence will change him. Then, create a plot outline. Maybe start with Harry arriving in the past in a dramatic way, like through a mysterious portal. After that, think about the conflicts that will arise. For example, how will the wizarding community of that time react to Harry's strange ways? And don't forget to add some emotional moments, like when Harry and his grandfather have a heart - to - heart talk about family values.
One possible plotline could be that Harry's grandfather imparts unique magical knowledge to him that he doesn't get at Hogwarts. Maybe it's an old - fashioned kind of magic that has been forgotten over time. This could give Harry an edge in dealing with the dark forces.
