The theme of the outsider is often present. Hermione, as a Muggle - born in the wizarding world, and Greyback, as a werewolf shunned by society, are both outsiders in a way. Fanfictions may explore how they connect on that level. Additionally, the theme of mystery is common. There's always the mystery of what Greyback will do next and how Hermione will react, which keeps readers on the edge of their seats.
One common theme is danger. Since Greyback is a werewolf, there's always the threat he poses to Hermione. For example, in many stories, she has to constantly be on guard against his predatory nature.
One common theme could be redemption. Since Fenrir is a rather dark character, the fanfiction might explore the idea of him being redeemed through his relationship with Hermione. Another theme could be the struggle between good and evil within the relationship. Hermione represents good and Fenrir represents evil, and their relationship could be about how these two forces interact.
One common theme could be the power struggle. Since Fenrir is a werewolf and Hermione is a powerful witch, their relationship in the fanfiction might revolve around the clash of their different powers and how Hermione tries to resist Fenrir's obsession. Another theme could be the idea of redemption. Some stories might explore whether Fenrir can be redeemed through his relationship with Hermione.
Another theme is the concept of redemption. Some fanfictions may try to show Greyback having a chance at redemption, perhaps through his interactions with Harry. It's an interesting take on his character. For example, in some stories, Harry might try to reform Greyback. This shows the power of compassion and the potential for change even in the most 'evil' of characters. And it also reflects on Harry's character as someone who believes in the possibility of redemption for all.
One possible theme is redemption. Maybe the fanfiction explores the idea of Greyback being redeemed through his interaction with Hermione. This could be appealing as it shows the power of goodness (represented by Hermione) over evil.
One key theme is danger. Fenrir is a dangerous werewolf, and his following Hermione puts her in constant peril. Another theme is the power of intelligence. Hermione uses her brains to try and figure out his motives and stay safe.
One common theme is the struggle against prejudice. Since Greyback is a werewolf, they often face discrimination, and the fanfictions show how they deal with that while maintaining their relationship.
One common theme is the exploration of his lycanthropy. Fanfictions often go deep into how being a werewolf has shaped his life and actions. For example, how it has made him an outcast in the wizarding world and how that has led to his bitterness.
In some fanfictions, the relationship between Hermione and Greyback might be a dark and twisted one. It could be used to show the contrast between good and evil in the wizarding world. However, this also poses challenges in terms of character development. Writers need to be careful not to stray too far from the established personalities of the characters in the original Harry Potter series.
There could also be a fanfiction where Hermione Granger is forced to face Fenrir Greyback alone in a dangerous situation. This would showcase her bravery and her ability to use her magic skills under extreme pressure. The story could focus on her mental and magical struggle against Greyback, perhaps with her using some of the more advanced spells she has learned over the years to defend herself and those around her from the werewolf's attacks.
