What are some interesting ideas in Harry Potter monster girls fanfiction?

Another interesting plot could be that some of the monster girls are actually descendants of ancient magical creatures that were once allies of the founders of Hogwarts. Harry and his friends try to form an alliance with them to restore the old magic that can defeat the dark forces. The monster girls might have different forms and powers, like a werewolf - girl who has super strength and enhanced senses during full moons.

Well, a great plot for this fanfiction could be that the Ministry of Magic is secretly breeding monsters for some dark purpose. Harry stumbles upon this and decides to become the monster slayer to put an end to it. He might face many challenges, such as being hunted by the Ministry's aurors who are trying to protect this secret. Also, he could encounter a monster that has the ability to change its form, making it extremely difficult to track and fight. Harry would need to use his intelligence and the help of his friends to overcome this.

Perhaps a group of wizards and witches form an alliance with Monster Hunters to stop a powerful dark magic - infused monster that is terrorizing both the wizarding world and the Monster Hunter's territory. They have to exchange knowledge, like the wizards teaching the Monster Hunters about potions for healing and the Monster Hunters showing the wizards how to use their unique weapons more effectively.

One idea could be a quest where the main character has to rescue a monster girl who has unique magical abilities that are crucial to the wizarding world. Maybe she can communicate with magical creatures in a way no one else can, and dark forces want to use her for evil. So the protagonist teams up with his Hogwarts friends to find and protect her.

The vampire - like monster girls are often quite popular. Their allure and the mystery surrounding their existence make them interesting. They can have powers like super speed and the ability to charm others, which adds a lot of drama to the story. Another popular type is the centaur - like monster girls. Their connection to nature and their own unique culture within the fanfiction world attract readers.

A fanfiction could focus on a monster girl's birthday celebration. Since they have different cultures, it would be interesting to see how the human characters plan a party that combines both human and monster girl traditions. They might struggle to find the right kind of cake or presents that suit the monster girl's tastes.

Perhaps a story about a group of outcast students who form a secret society dedicated to monster slaying. They are not the typical popular or top - performing students at Hogwarts. Instead, they are misfits who have been bullied or overlooked. But together, they use their combined skills and the power of friendship to take on the most terrifying monsters in the wizarding world.

One interesting idea in 'Harry Potter' fanfiction is the concept of alternate universes. For example, a fanfic might explore what would happen if Harry was sorted into Slytherin instead of Gryffindor. This could lead to a completely different set of relationships and storylines. Another idea could be time - travel fanfics where characters go back in time to change certain events in the wizarding world's history. It adds a whole new layer of complexity and intrigue to the original story.

Maybe a mermaid girl. Since there are water elements in the Harry Potter world as well. She could live in the Black Lake at Hogwarts and help Harry when he has to deal with water - related challenges. Her mermaid magic could be something completely new for Harry to discover.

One idea could be that Harry discovers a hidden part of the wizarding world where there are 'monster girls'. Maybe he stumbles upon a secret club at Hogwarts. Through his interactions with them, he learns about their unique cultures and magic. This could lead to him wanting to be more involved with their world, perhaps even using his skills to help them with problems they face.
