Harry Potter himself is often a central character. Writers like to put him in situations where he uses his magic in the zoo setting, like when he has to rescue a trapped magical creature that has somehow ended up in the zoo. His sense of justice and adventure makes him a great fit for these stories.
Hermione could be a major character. She would be really helpful with all her knowledge, maybe helping Harry with the care of the magical creatures and coming up with ways to educate the visitors. Ron might also be there, perhaps handling the more physical tasks around the zoo like building enclosures for the larger creatures.
Obviously, Harry Potter himself. He's the main character and the one who can talk to snakes. Hermione might also show up. She's always curious about new things and would probably be interested in Harry's snake - talking adventure at the zoo. Ron could be there too, perhaps being a bit scared of the snakes at first but still supporting Harry.
Maybe Harry uses magic to create a unique zoo. He could have magical creatures from the wizarding world, like hippogriffs and unicorns. The zoo would be a place for both wizards and muggles to learn about these amazing beings.

He could be involved in humorous situations in the town, like getting into trouble at the local pub or trying to impress the town girls with his half - baked magical ideas. Luna Lovegood is another popular one. Her unique perspective on magic might lead her to discover strange and wonderful things in the town that others overlook.

Hermione Granger is also very popular. Her vast knowledge of magic and quick thinking make her an essential part of any survival group. She can come up with solutions to problems that others might not even think of, like using complex spells to create shelters or find food.
Harry Potter could also be a popular character. He might be the one who discovers the need for an auditor in the first place. Maybe he stumbles upon some strange financial activities in the wizarding world and decides to bring in an auditor to get to the bottom of it. His courage would be useful in protecting the auditor from any threats.
Hermione Granger is still a very popular character in fanfiction. Writers often like to explore her further studies and her role in solving more complex magical mysteries. She can be depicted as even more brilliant and resourceful, taking on challenges that the original series only hinted at.
Ron Weasley is often included as well. His humorous nature and loyalty to his friends can add a lot of charm to the story. And Neville Longbottom can also be a popular character in these fanfictions. He could be depicted as having newfound confidence and strength, being an important part of the team.
