One common theme is acceptance. It often explores how Snape, as a trans character, seeks acceptance in the rather traditional and sometimes unforgiving wizarding society. Another theme is identity struggle. He has to deal with his own understanding of his gender while also dealing with the expectations of others around him. For example, in Hogwarts, he might face discrimination or misunderstanding from students or other staff members.
In Severus Snape fanfiction, his past and how it shaped him is a common theme. This includes his childhood, his time at Hogwarts as a student, and his early encounters with the Death Eaters. His redemption arc is also frequently explored, as readers are interested in how he managed to turn his life around and do good in the end despite his earlier actions. And of course, his relationships with other characters like Dumbledore, Harry Potter, and the other Hogwarts professors are often the focus of these stories.
One common theme is redemption. Since Snape has had a rather complex and morally ambiguous past in the original story, in these fanfictions, his survival often leads to him seeking redemption. He tries to make up for his past mistakes, especially those related to his treatment of students like Harry Potter. Another theme is self - discovery. Surviving gives him a chance to explore parts of himself that he may have neglected or been unable to before due to his loyalty to Dumbledore and his role as a spy. For example, he might discover new interests or talents.
One common theme is his relationship with Lily. Fanfictions often explore how his love for her started, grew, and how it affected him. For example, in many stories, his actions are directly or indirectly related to his feelings for Lily.
One common theme is the exploration of Snape's hidden emotions. Since he was a very reserved character in the original series, fanfictions often dig deeper into his feelings, especially in the context of a gay relationship. Another theme is the struggle against the wizarding society's norms, as the wizarding world in Harry Potter doesn't really touch on homosexuality much. And of course, there's the theme of love and loyalty, just like in any relationship - based fanfiction, but with a gay twist on Snape's character.
One common theme is redemption. Since Snape had a complex and often misjudged life in the original series, many fanfictions focus on him getting a second chance to redeem himself in his new life. For example, he might correct the mistakes he made with Lily or his students.
One common theme is his relationship with Lily. Writers often explore how his abuse might have affected his feelings for her and how it influenced their interactions. Another theme is his time at Hogwarts as a teacher. How his past abuse made him act the way he did towards students, like Harry.
The theme of redemption through love can also be found. The character with a crush on Snape might see the good in him despite his flaws and past mistakes, and through their love, there's a sense of Snape being redeemed in some way. Also, the idea of forbidden love is common, especially when the person with the crush is a student or someone in a position where a relationship with Snape would be considered inappropriate.
One common theme is redemption. Despite being in a slave - like position, Snape often tries to find a way to atone for his past actions or mistakes. Another theme is power dynamics. It shows how power can be misused and how those in a subservient position, like Snape in these fanfictions, can resist or adapt.
One common theme is identity. Since she is Snape's daughter, she often struggles with defining herself apart from her father's complex legacy. Another theme is acceptance, both from the Hogwarts community and within her own family. For example, in many fanfics, she has to prove herself worthy to be in Slytherin like her father.
Power and control are also common themes. Being a vampire might give Snape additional powers, and the fanfictions often explore how he uses or misuses these powers. There's also the theme of secrecy. Snape has always been a secretive character, and as a vampire, he has even more secrets to keep, which adds to the overall intrigue of the stories.
