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.
Perhaps Harry would include potions inspired by his adventures. He could make a 'Chamber of Secrets' potion that gives a sense of courage when facing one's fears. He'd need to deal with competitors too. Some might try to steal his potion recipes. But with his Gryffindor bravery and the loyalty of his friends, he'd be able to overcome these challenges and build a successful potion shop.
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.
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.
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.
Maybe Harry goes there to buy a special potion for his next adventure. He might be greeted with a cold stare from Draco at first, but then Draco realizes it's just business.
In a Harry Potter polyjuice potion mishap fanfiction, the person who drinks the potion wrongly might start to exhibit the wrong personality traits. Let's say they were trying to transform into Hermione but due to the mishap, they start acting like Draco Malfoy instead. This would cause chaos as they would be doing things completely out of character for the person they were supposed to be imitating. They might start bullying other students or being mean to their friends, creating a lot of drama and confusion in the wizarding world.
In this fanfiction, Harry could use his extensive knowledge of potions from his Hogwarts days. He might create unique potions that combine the traditional magic of potions with his own experiences. For example, a potion that gives the drinker a sense of calm during a Dementor encounter, using the essence of happy memories as an ingredient. He could also hire some of his old classmates like Neville, who has a great talent for Herbology, to supply rare ingredients for the shop.
Well, someone might end up with a really strange combination of features. For example, they could have the body of one character but the voice of another completely different character. It could lead to all kinds of misunderstandings. Maybe they try to blend in with a group but because of the mess up, they act in a way that gives them away immediately.
He would manage it with his Gryffindor courage. He'd face challenges like potion ingredient shortages head - on. Maybe he'd form alliances with magical creatures to get rare ingredients. For instance, working with the centaurs to get special herbs.
Well, he might use magic to create the most amazing pastries. His Firebolt skills could translate to lightning - fast kneading of dough. And his Hogwarts friends would surely visit often, like Hermione might help with the bookkeeping using her intelligence and Ron would be there to taste - test everything.
Well, he might serve magical drinks like Butterbeer-flavored coffee. His cafe could be a place where wizards and muggles alike gather. He could use magic to decorate the place with floating candles and moving portraits. Maybe his friends from Hogwarts would help out, like Hermione managing the accounts with her intelligence and Ron being in charge of the food tasting.
