One idea could be a crossover where Harry Potter characters visit the Pride Lands. For example, Hermione could use her magic to help solve some of the problems in the Lion King's world, like finding a new water source during a drought. Another idea is that Simba could be sent to Hogwarts for some reason and has to learn magic while dealing with the Hogwarts politics. Maybe the Sorting Hat has a hard time deciding which house to put him in because he has qualities of all the houses.
One idea could be to explore what would happen if Simba had a different mentor. For example, instead of Rafiki, it could be a new character who teaches him a different way of leadership. Another idea is to create a story where the hyenas reform and try to integrate into the pride. Maybe they realize the error of their ways after Scar's downfall and want to make amends.
One idea could be an anthro version where the characters are in a modern-day city. Simba could be a young entrepreneur trying to make his mark in the business world while still dealing with the legacy of his father. Another could be an anthro story where the animals form a sort of United Nations - like organization to deal with inter - species conflicts. For example, the lions, hyenas, and other animals come together to discuss territory and resource sharing.
One idea could be creating an OC (original character) who is a long - lost relative of Simba. This OC could arrive in the Pride Lands with a unique skill, like being able to communicate with a different type of animal that the lions usually don't interact with. For example, a small rodent that has knowledge of a hidden danger approaching the Pride Lands.
A fanfiction could also be about the hyenas getting a second chance. Maybe they find a new place to live and try to form a more positive community, with some help from the lions.
One interesting idea could be a fanfic that focuses on the Marauders' time at Hogwarts. It could explore their pranks, friendships, and how they came to be the legends that we hear about in the original books. For example, showing how they created the Marauder's Map in more detail.
One interesting idea could be a fanfic where the Marauders attend Hogwarts during modern times. They'd have to deal with things like smartphones and social media while still maintaining their mischievous ways. Another could be a story that focuses on the lives of the house - elves after the events of the books, perhaps exploring their newfound freedom. And a third idea could be a fanfic about a new dark wizard emerging in the wizarding world years after Voldemort's defeat, and how the new generation of Hogwarts students respond.
A great 'Harry Potter fanfic' idea might be a story that delves deeper into the relationship between Snape and Lily. Maybe a fanfic where Snape has a chance to change the past and save Lily in a different way. Another idea is to write a fanfic about the ghosts in Hogwarts and their backstories, like how they died and why they chose to stay at the school. Additionally, a story where the Weasley twins open a magical joke shop in a different country and the challenges they face there would be really interesting.
One interesting idea could be exploring the lives of the minor characters more in - depth. For example, what was Neville Longbottom's life like during the summers at home? Another idea is to create an alternate ending to the series. Maybe Voldemort could have been redeemed instead of defeated. Also, a fanfic could focus on the magical creatures and their own society within the wizarding world.
One idea could be that the Demon King somehow infiltrates Hogwarts. Maybe he disguises himself as a new professor. This would lead to a lot of mystery and danger as Harry and his friends try to figure out who he really is.
Another possibility is a human who has a special power, like being able to communicate with all animals. They come to the Pride Lands during a time of trouble, such as a drought or an invasion from another group of animals, and use their power to help the lions and other creatures.
