Who might be the first customer in 'Harry Potter opens a pet shop' fanfiction?

Well, he might sell magical creatures like owls, toads, and perhaps even some rare and exotic ones like hippogriffs. He could use his knowledge of magic to take care of the pets and also teach the customers how to handle them properly.

Definitely Hogwarts students. They'd come during their free time or on trips to Hogsmeade. They'd be eager to try Harry's special magical treats.

Other potion shop owners might visit too. Not as customers in the traditional sense, but more to check out the competition. They might be curious about Harry's unique potions. And then there are the local wizards and witches in the area where the shop is located. They could need potions for daily life, like a potion to make their gardens grow better or a potion to keep their pets healthy.

Hermione would probably be one of the main characters. She's smart and resourceful, so she could help Harry with the administrative side of running the orphanage, like handling finances and paperwork. Ron might also be involved, perhaps teaching the orphans some practical magic skills. And of course, there could be some of the orphans themselves as main characters, like a young girl with a special magical ability that Harry discovers.

Well, he might create some unique potions. Maybe a potion that can make people temporarily have the ability to speak Parseltongue. It would attract a lot of curious wizards and witches to his shop.

Well, he might open a magic shop. He could sell all kinds of magical items like self - writing quills, enchanted maps, and potions. Maybe his friends would help him run it. For example, Hermione could manage the accounts and Ron could test the products.

His Hogwarts friends would probably be the first. Hermione would be eager to check out any new books or intelligent - enhancing potions. Ron would be interested in any food - related magical items, like everlasting candies.

One main character could be a young, aspiring wizard who has always dreamed of having a magical pet. He visits the pet shop regularly to look at all the amazing creatures. Another could be the eccentric old owner of the pet shop who has a wealth of knowledge about magical pets.

Harry Potter himself could be a main character. He might be on a mission to find a pet for a friend or to solve a mystery related to the pet shop. Hermione would also be a great choice as she's always interested in learning about new magical creatures. And Hagrid, of course, with his love for all beasts, could play a major role.

One possible plot could be that a new, mysterious pet appears in the pet shop in Diagon Alley. This pet has some unique magical abilities that no one has ever seen before. A young witch or wizard discovers it and tries to figure out its origin and how to take care of it. Maybe it's a key to an ancient magic mystery.
