A time - traveling wizard could be another interesting character. They could come from a far - off future where magic has evolved in different ways. They might accidentally end up in the time period of the fanfic's main story and cause all sorts of chaos and also bring new knowledge of magic that has been lost or not yet discovered in that time.
There could be a half - elf, half - vampire character. This character would struggle with the duality of their nature. On one hand, they have the elegance and long - life of a vampire, but on the other, the connection to nature and magic of an elf. They would be an outcast in both elf and vampire communities and find their place among the wizards in the Harry Potter - like fanfic world.
Well, in Harry Potter fanfic, Justin Finch - Fletchley can be an interesting Hufflepuff character. He was a Muggle - born Hufflepuff, and fanfics could tell stories about his initial shock and adjustment to the wizarding world from a Hufflepuff perspective. Pomona Sprout, the Hufflepuff head of house, is also a great character in fanfics. Fanfic authors might write about her teaching methods and how she instilled Hufflepuff values in her students, like her nurturing nature and love for plants which could be tied to the Hufflepuff traits of kindness and patience.
One interesting centaur character in Harry Potter fanfic could be Firenze. In fanfics, he might be further explored in his role as a teacher at Hogwarts. For example, there could be stories about his interactions with students outside of the classroom, and how he imparts his unique centaur wisdom. He could also be involved in adventures that test his loyalty to Hogwarts and his centaur herd.
One great idea could be a fanfic about the characters' adventures during their summer holidays that they don't mention in the books. For example, Hermione could be exploring ancient magical libraries in other countries and having friendly competitions with other young wizards she meets there.
One interesting Ravenclaw character in fan fiction could be Luna Lovegood. In many fan fictions, she is often explored more in - depth, like her post - Hogwarts adventures. Another could be Cho Chang, who might be given new storylines related to her Ravenclaw intelligence and how it affects her relationships. There are also original Ravenclaw characters created by fans, who might have unique magical abilities or quirks.
One common character is Sherlock Holmes. His deductive skills add an interesting dynamic to the magical world of Harry Potter. Another could be Frodo Baggins from 'The Lord of the Rings'. Imagining him in Hogwarts, perhaps trying to resist the allure of the One Ring while also dealing with Hogwarts' mysteries is quite fascinating. And then there's Alice from 'Alice in Wonderland'. Her curious and often bewildered nature could make for some really unique interactions within the walls of Hogwarts.
One character could be Hermione Granger. In many fanfics, she is often depicted as being interested in exploring different interpretations of the Harry Potter universe in fan - written stories. She has a great love for books and knowledge, so she would be curious about fanfictions that expand on the world she already knows.
Neville could be an unexpected hero in such a fanfic. He might have some special knowledge about plants that could help the shrunken characters. For example, he could use a magical plant to grow them back to their normal size. And of course, Dobby the house - elf could play a role. He could be the one to discover the shrunken characters and try to protect them from the other wizards who might accidentally step on them.
Well, there are themes like the development of new spells. The characters could be in a spell - creating club where they try to come up with innovative magic. Friendship is also a huge theme that can be explored more deeply. For example, how the friendship between different houses evolved over time. Also, exploring the different types of magic in different cultures within the wizarding world, like the magic practiced in other countries that we don't hear much about in the original books.
There are 'Harry Potter fanfic fanfic' that focus on time - travel scenarios. Imagine if a character from the later books travels back in time to the first year at Hogwarts. This can create a lot of interesting plot twists as they try to change or preserve the original story line. Also, some fanfic fanfic might center around magical creatures in a way that wasn't fully explored in the original books, like the life of a hippogriff in more detail.
Neville Longbottom could be one. Neville is a character who has grown a lot throughout the series. He has a love for magic and the wizarding world. Fanfics can provide new adventures and perspectives on the things he already loves. He would be interested in reading about how other fans imagine the world he lives in.
