One common theme is the forbidden love. Since Sebastian is a demon, his relationship with a human or other non - demon entity is often seen as something that goes against the natural order. Another theme is redemption. Sometimes the love story is about Sebastian finding a path to redemption through his love for someone. And of course, there is the theme of power struggle. If his love interest has some power, there is often a push - and - pull between their powers as they navigate their relationship.
One common theme could be the complex relationship between Sebastian and other characters. It often explores the power dynamics and the allure that Sebastian has.
One common theme is the power dynamic between Sebastian and the love interest. Given Sebastian's demon nature, there's often a play between his dominance and the love interest's humanity. Another theme could be redemption. Maybe the love story is a path for Sebastian to find some form of redemption from his dark deeds. Also, the theme of forbidden love is prevalent as a demon-human relationship goes against the natural order in the 'Black Butler' universe.
One common theme is rivalry. Since both characters are quite powerful in their own right, many fanfics explore their competitive nature towards each other. They might compete for a certain goal or for the attention of another character.
Another theme is the struggle between his demonic nature and any emerging humanity. Some fanfictions show him experiencing emotions that are not typical for a demon, like compassion or love, and how he deals with that.
Power dynamics is also a big theme. Sebastian is a powerful demon and Ciel is a young earl. The way they interact with each other in terms of who has the upper hand, and how that changes over time is often explored. For instance, in some fanfics, Ciel tries to gain more power over Sebastian, or Sebastian uses his power to protect Ciel in unexpected ways.
One possible fanfic could be about Sebastian falling in love with a human girl who is kind-hearted and brave. She might be a young noblewoman who is different from the typical spoiled aristocrats. Sebastian is initially intrigued by her uniqueness and as time passes, he starts to feel emotions he has never experienced before. Their relationship develops as they face various challenges together, like dealing with other demons who oppose their relationship or the strict social norms of the Victorian era.
One common theme is the clash of different worlds. Since it's a crossover, Sebastian is often taken from his original 'Black Butler' world and put into a new one. So, you get to see how his demon nature and values interact with the new setting's norms.
Many baby Sebastian Michaelis fanfictions have the theme of mystery. Since we don't know much about his early days in the original work, writers create stories full of mystery surrounding his baby years. They might introduce new elements or events that could have shaped him, like a hidden power or a fateful encounter that we didn't know about before.
One possible theme could be redemption. If the broken wings represent a fall from grace or a past mistake, then love in the story might be the path to redemption for the character. Another theme could be acceptance. Sebastian Michaelis might need to accept the flaws and the brokenness of the other character.
Well, a frequent theme is the exploration of morality. Harry Potter is often associated with good and fighting against evil, while Sebastian Michaelis has a more ambiguous moral standing. Fanfictions might explore how their different moral compasses interact when they meet. Also, there's the theme of loyalty. Both characters have their own loyalties in their respective stories, and in fanfictions, these loyalties can be tested or redefined when they cross paths. And of course, there's the theme of mystery. Sebastian's nature as a demon butler is mysterious, and in the world of Harry Potter, there are also many mysteries, so these can be combined in interesting ways in the fanfictions.
