Dobby could be a great butler. He was always eager to serve Harry and was very loyal. His knowledge of the Malfoy manor and other wizarding households could be useful. And his unique brand of magic, like his ability to apparate in and out of places where other wizards couldn't, would add an interesting dynamic to the story.
I think Sir Ian McKellen would be a great choice. He has that air of elegance and mystery about him. His acting skills are top - notch and he could bring a lot of depth to the role of the butler.
Dobby could be a great character as a butler in fanfiction. He already has a strong loyalty to Harry and his self - sacrificing nature would make him an excellent butler. He could use his house - elf magic to keep Harry's living quarters clean and protected.
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.
Another option could be Michael Caine. He has that classic British charm and elegance that would be perfect for a butler role. He could bring a sense of humor and warmth to the character, while still being able to handle the more serious and magical aspects of the story.
The butler could be a protector. He might use his skills, like combat skills or knowledge of ninjutsu, to keep Naruto safe from various threats, whether it's rogue ninjas or political schemes.
Yes, there might be some fanfiction that has such an interesting and rather unique concept. Some fanfic writers like to create crossovers and put unexpected twists in them. They might imagine Harry Potter as a cat within the world of Black Butler for various reasons, like exploring different character dynamics or just for the fun of it.
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 possible plot could be that the butler is actually a wizard in disguise who has been sent to protect Harry. He could use his knowledge of the wizarding and Muggle worlds to keep Harry safe from both magical threats like Death Eaters and Muggle dangers. For example, he could use his connections in the Muggle world to find safe houses for Harry when he needs to hide from Voldemort.
Well, the plot could involve the cat - Harry Potter - stumbling into the Black Butler world. Maybe he's lost his human form due to some dark magic. He could then encounter Sebastian and Ciel. The cat - Harry - might use his magic in cat form to help or hinder the duo in their investigations. For example, he could use his invisibility ability (in cat form) to spy on enemies.
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.
