It could be Bellatrix Lestrange's younger sister who was not as involved in the dark arts as Bellatrix. She might be a character who was forced into the shadows because of her family name but has a good heart. Harry's betrothal to her could be a way to redeem the Lestrange name in the eyes of the wizarding world.
Voldemort is often paired with Bellatrix in fanfiction. Their relationship in the original series was one of master and servant, but in fanfiction, it can be explored in more complex and romantic ways. Another character often paired with her is Narcissa. Their sisterly bond can be a central focus, or it can be twisted into something more sinister or complex in fan - created stories. Also, sometimes Sirius Black is paired with her in alternate universe stories, given their family connection and the contrast in their loyalties.
Hermione is known for her strong sense of justice and intelligence. The Lestrange brothers, coming from a dark pure - blood family, might have a more cavalier attitude towards the law and a different view on power. Hermione would clash with them when it comes to ethical use of magic. For example, she would never condone their use of dark spells for personal gain. Her studious nature would also contrast with their more impulsive and power - hungry ways.
No. Harry Potter is a unique and original story created by J.K. Rowling. It has its own independent world - building, characters, and plotlines that are distinct from fanfiction. Fanfiction is typically based on existing works by fans, while Harry Potter is a fully - fledged, professionally - written series.
The main distinction of porn with a story genre from regular porn is the presence of a coherent narrative. Regular porn often jumps straight to the sexual action, while the story genre tries to add some kind of story framework around it. But in the end, both are adult-oriented and feature explicit sexual content.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
