Who could Harry meet when he goes to Diagon Alley in fanfiction?

He could meet a young and brilliant wizard inventor. This inventor is working on some newfangled magical gadgets and shows Harry some prototypes, like a self - flying broomstick that can change its shape according to the rider's mood.

He might meet some shady characters like Borgin and Burkes. They deal in all sorts of strange and often dark items.

One possibility is that their meeting is not so friendly at first. Daphne, coming from a certain Slytherin - pure - blood mindset, might be a bit haughty towards Harry. But as they talk, Harry's kindness and honesty could break through her initial prejudice. They could end up having a deep conversation about the differences between the houses at Hogwarts, and how they both want to make the most of their time at school, despite their different backgrounds.

Well, he could meet some new and mysterious characters. Maybe a young wizard with a strange power who becomes his friend or an old wizard with a hidden agenda. He might also discover a new magical shop that sells unique items not found in the regular Diagon Alley stores.

Well, he might encounter a new magical creature that is not in the original books. For example, a tiny dragon that can speak and becomes his little friend, guiding him through the Alley and showing him some hidden shops.

Maybe it's a new character created by the fanfiction author. This new character could have special abilities or a unique backstory that ties into the reason for escorting Harry to Diagon Alley.

Well, in some fanfictions, it could be due to a powerful spell gone wrong that transfers the ownership to him. Maybe a spell meant to protect Diagon Alley's property rights backfires and suddenly Harry is the owner.

He might have to deal with a lot of administrative work. Running Diagon Alley means taking care of all the shops, making sure the wizards and witches who work there are happy, and dealing with any disputes. For example, if two shop owners have an argument over a piece of land in Diagon Alley, Harry would have to step in and sort it out.

It could be an old, retired Auror. They would have a wealth of practical knowledge about magic and how to use it in dangerous situations. They could teach Harry how to sense dark magic and protect himself better.

In the fanfic, it might lead to a tense confrontation. Harry could feel anger towards the Malfoys as they are known for their prejudice. Draco might taunt Harry as usual, and Lucius Malfoy could look down on Harry with his typical haughty attitude.
