One possible plot could be that Harry discovers his half - ghost nature gradually. Maybe he starts having strange abilities like being able to pass through some objects slightly or having a strange, cold aura around him sometimes. This could lead to him being ostracized by some at Hogwarts who are afraid of the unknown, while others are curious and want to help him figure out what it means.
Hermione would likely still be a main character. She would probably be the one trying to research about Harry's half - ghost condition, scouring the library for any information on half - human, half - ghost beings in the wizarding world. She might also be the one to help Harry control his new abilities when they get out of hand, using her vast knowledge of magic.
I'm not entirely sure if there is a specific 'Harry Potter is half demon' fanfiction, but considering the limitless creativity in the fanfiction community, it's very likely. Writers might be inspired to create such a story to explore the contrast between the magical world of Harry Potter and the more dark and otherworldly concept of being half - demon. They could use it to examine themes like acceptance, identity, and power in a whole new light.
The allure of 'Harry Potter' half - elf fanfiction lies in the mystery it can bring. Half - elves are not part of the original lore in a big way, so writers can be very creative. For example, they could create a half - elf character who has a secret power that helps Harry in his fight against Voldemort.
In some fanfictions, it could be an original character created by the author. Maybe a witch who was the result of an affair that his father had before he married his mother. However, this is completely against the canon of the original books, but in the world of fanfiction, anything is possible.
One possible plot could be that a half - human half - horse character helps Harry Potter find a hidden magical artifact. The half - horse's speed and knowledge of the Forbidden Forest could be key elements in this adventure.
One common theme is identity struggle. Since the character is half - vampire and half - werewolf, they often struggle to figure out where they belong in the wizarding world. Another theme is secrecy. They usually have to hide their true nature from others to avoid being ostracized.
In some fanfictions, the 'half angel half devil' aspect of Harry Potter might manifest in his powers. He could have angel - like abilities such as the power to heal or protect in a very pure and benevolent way, which is typical of angelic characteristics. At the same time, he might have devil - like powers like being able to access dark magic more easily or having a more aggressive and unpredictable side. This duality could also be reflected in his personality. He may be extremely kind and selfless at times, similar to an angel, but then have moments of anger or be tempted by darker forces like a devil would be.
In many Harry Potter fanfictions, half - giants are often portrayed as having great physical strength, just like Hagrid in the original series. They might be shown as having a gentle heart beneath their tough exterior. For example, some fanfictions might explore a half - giant character's struggle to fit into the wizarding world due to their large size and different nature.
Yes, there are likely some fanfictions out there with this concept. Fanfiction writers often come up with unique and creative ideas, and the idea of Harry Potter being half - elf is an interesting and different take on the character. However, the quality and nature of such fanfictions can vary greatly.
