Well, in Harry Potter fanfics, cats could play various roles. They might be the pets of students at Hogwarts, like Crookshanks was Hermione's. In Black Butler, a cat could be used as a symbol of mystery. It could be related to the dark undertones of the story, maybe a cat that is somehow connected to the demons or the underworld in the fan - made story.
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.
Regarding cat in Harry Potter and Black Butler fanfiction, in Harry Potter world, cats can be carriers of magic and secrets. They might be involved in hidden passages or magical spells. In Black Butler, a cat could be a contrast to the dark and often human - like demons. It could represent a more innocent and yet still somewhat mysterious element, adding an interesting dynamic to the fanfiction.
In Harry Potter fanfics, a cat could be a magical being from a different realm that comes to Hogwarts. It could have special powers like the ability to see through invisibility cloaks. In Black Butler, a cat could be a sign of good luck or bad omen in the fan - created story. It could be associated with a particular event or character, like if a cat always shows up before a major event in the Phantomhive household, it could be seen as a harbinger of things to come.
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.
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.
Ciel is also very popular. Picture a scenario where Ciel finds a cat and decides to keep it. The dynamic between him, a young noble with a dark past, and the cat can create some really heart - warming or suspenseful moments. The cat could either be a source of comfort for Ciel or bring new challenges to his already complex life.
I really like 'Ciel's Cat Adventure'. In this fanfiction, Ciel as a cat encounters various characters from the series in unexpected ways. It's a light - hearted read compared to some of the darker aspects of the original Black Butler, but still manages to capture the essence of the characters. It shows Ciel's intelligence even in his cat form as he navigates through different situations.
One common theme is mystery. The cat often brings an element of mystery to the story. Another is loyalty, as the cat might be fiercely loyal to a particular character.
Sure. In fanfiction, anything is possible. If we consider the idea of Harry Potter as a reaper in the Black Butler world, it could open up a lot of interesting plotlines. For example, his Hogwarts training in magic could interact with the reaper's duties in the Black Butler world. Also, his relationships with other characters from the Potterverse could be re - imagined in the context of Black Butler.
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.
