One idea could be to create a story where a new student arrives at Hogwarts with a unique and powerful form of magic that no one has seen before. This could lead to all sorts of adventures and challenges as they try to fit in while also dealing with those who might be jealous or afraid of their power.
First, focus on creating unique and well - developed characters. Don't just rely on the existing characters from the books. Invent new ones with their own personalities, backstories, and motives. This will make your fanfic more original. For example, a wizard who has a phobia of using magic wands but has to find alternative ways to cast spells.
Another possibility is that Harry interacts with some of the administrative staff in the DMLE. They might be the ones who first take his call and record the details. They could play a role in passing the information on to the relevant people within the department, and Harry might have to convince them of the urgency of the situation.
In the fanfic, Harry Potter could meet the new generation of students. They would be in awe of him. He might also encounter some of the ghosts, like Nearly Headless Nick, who would surely have some interesting stories to share since Harry left. And there's a good chance he'll meet the caretaker, who would probably give him a hard time about coming back and causing a stir. Moreover, he could cross paths with some of the older students who idolize him and want to learn from his experiences.
Well, it could be that Harry Potter discovers he has a connection to Sparda. Maybe he has some latent power that is related to Sparda's abilities. He then has to learn to control this new power while still dealing with the threats in his own wizarding world. And perhaps he uses his new - found powers to fight off dark wizards in a more badass way.
It might involve Moriarty somehow infiltrating the wizarding world. He could use his intelligence to manipulate magical politics or try to steal powerful magical artifacts for his own gain, much like he does in his own original story but with a magical twist.
In a 'Harry Potter is a Baker' fanfic, Harry might be using his magic to add a special touch to his baking. For example, he could use a spell to make his dough rise instantly or his cakes have a unique, magical flavor. He could also meet other magical beings in his bakery, like house - elves who help him out in the kitchen. And perhaps he uses his fame as 'The Boy Who Lived' to attract customers, but also has to deal with some who are just there for the novelty and not the actual baked goods.
Well, it could include the emotions of Harry's parents. Lily might have been feeling a mix of joy and anxiety. James would probably be very protective. Also, the description of their home, like how they decorated the nursery in a magical way, with floating mobiles of magical creatures.
It's difficult to say if there are popular 'no magic harry potter fanfic'. The Harry Potter fandom is vast and diverse, and while most fans are drawn to the magic, there may be some who have created or are interested in non - magic fanfics. However, these might not be mainstream popular. Some might exist in smaller communities or on less - known fanfic platforms. They could be created by fans who are looking for a new perspective on the series, perhaps exploring how the characters would be in a more 'normal' world without magic, but they likely haven't reached the same level of popularity as the more traditional fanfics.
A squib in the Harry Potter universe is a person born into a magical family but lacks the ability to perform magic. In a 'no magic' fanfic, it could be really interesting to explore how a squib might navigate the wizarding world. They might face discrimination or be overlooked. They could also find unique ways to contribute, like being really good at understanding magical artifacts even without being able to use them.
