One implication could be the confusion of the two fan bases. Fans of Harry Potter might be put off by seeing their beloved characters in a context that doesn't align with the original series. Similarly, Black Butler fans may not appreciate the distortion of their favorite story.
There could be issues regarding copyright and respect for the original works. While fanfiction is a form of creative expression, this type of crossover in a way that distorts the essence of both series could potentially cross the line. It might also lead to a negative perception of fanfiction in general among some people who view it as misusing the original IPs.
From a storytelling perspective, it would be extremely challenging to create a coherent narrative. The magic systems, character personalities, and the overall themes of the two series are very different. For example, Harry Potter's magic is more about spells and potions, while Black Butler has a more supernatural and dark - themed magic related to demons. Trying to merge them would require a great deal of creativity and might end up being a jumbled mess.
In the world of fanfiction, there are often very creative and out - of - the - box ideas. However, 'harry potter is a demon black butler fanfiction' seems more like a misappropriation. Harry Potter is about a boy wizard's journey through a magical school and his fight against the dark lord. Black Butler is about a young noble and his demon butler. Mixing them in this way just doesn't fit well.
One implication could be a change in his powers. If Harry is part demon, he might have some darker or more unruly powers compared to his normal wizard abilities. For example, he could have the ability to manipulate emotions in a more forceful way.
In Harry Potter fanfiction, a cat could be a magical familiar. For example, it might be a cat that can transform into a wizard's assistant when needed. In Black Butler fanfiction, a cat could be part of the Victorian - era setting, perhaps a stray that Ciel and Sebastian encounter on the streets of London.
One idea could be a crossover where the characters from Harry Potter end up in the world of Black Butler. For example, Harry, Hermione and Ron could be mistaken for some kind of strange magical beings in the Victorian era of Black Butler. They might be brought to the Phantomhive manor and Sebastian has to figure out what to do with them. Maybe they are there to solve a mystery that involves both the magic of the Harry Potter world and the dark secrets in the Black Butler universe.
Another theme is the moral grayness. Both universes have characters that exist in that morally ambiguous area. Fanfictions tend to play with this, like when characters from Harry Potter are faced with the more cut - throat and often morally complex situations in the Black Butler world. For example, how would Harry react to some of the deals and sacrifices that are common in the Black Butler world? It makes for some really thought - provoking reading.
A character like Severus Snape could be an interesting choice. He already has that mysterious and somewhat dark aura about him. Transforming him into a demon butler would add an extra layer of complexity to his character, and his relationship with Harry could be re - imagined in a whole new way.
One interesting crossover could be the characters from Black Butler ending up at Hogwarts. Maybe Sebastian could be disguised as a new professor, teaching a class on dark magic in a very unique way. His butler skills would surely make him stand out among the Hogwarts staff.
One great Black Butler and Harry Potter crossover fanfiction is 'A Butler in Hogwarts'. It has an interesting plot where Sebastian, from Black Butler, somehow ends up in the wizarding world of Harry Potter. He uses his skills to navigate the strange new place while also causing some chaos. Another good one could be 'The Dark Arts of a Demon Butler'. It combines the dark elements of both universes really well.
Another good one is 'The Potter - Phantomhive Connection'. This fanfiction delves deep into the relationship between a fem Harry Potter and the Phantomhive household. It shows how her presence disrupts and also enriches the existing dynamics. The writing is quite engaging, with detailed descriptions of the settings and the characters' emotions.
If Harry killed dementors in a fanfiction, it could have several implications. For one, it could be a sign of his growth and mastery of magic beyond what was shown in the books. It might also lead to a different relationship between him and the Ministry of Magic. Since dementors were used as guards in Azkaban, their deaths could cause chaos in the prison system. Additionally, it could change the perception of the dark side in the wizarding world, as dementors are a symbol of the darkest elements.
