Another option is to check out some Harry Potter - focused fanfiction communities or forums. Sometimes, members share or recommend specific fanfictions there. You can post a request asking for Fenrir and Hermione pregnant fanfictions, and someone might be able to point you in the right direction.
Fanfiction.net could also be a place to search. However, the quality and content can vary widely. You'll need to search specifically for 'Fenrir and Hermione' and then look for stories that involve the pregnancy aspect among the results. It might take some time to sift through.
One possible plot could be the challenges they face. Maybe Hermione is initially scared and conflicted about the pregnancy as Fenrir is a complex and somewhat dangerous character. Society might not accept their union, so they have to deal with secrecy and the judgment of others.
Harry and Ron would likely be very shocked and concerned. They know Fenrir is a dangerous werewolf, and they might not understand how Hermione got into this situation. They would probably try to persuade Hermione to leave Fenrir at first.
One common theme is the struggle with the unexpected nature of the pregnancy. Given Fenrir's complex and often villainous nature in the original Harry Potter lore, there could be a lot of internal conflict for Hermione. Another theme might be how the wizarding world reacts to such an unusual pairing having a child.
In many such fanfictions, Hermione might start by trying to understand Fenrir's situation from a research perspective. She could be using her extensive knowledge of magic and werewolves to figure out a way to help him. For example, she might look into any spells or potions that could ease his lycanthropy symptoms.
Well, it might be good because it could have an interesting take on the characters of Hermione and Fenrir. Maybe it explores their relationship in a unique way that we haven't seen before in the original works.
At the start, Hermione would be appalled by Fenrir's cruelty. She would be enraged that he has caused so much harm to innocent people. But as she delves deeper into getting to know him, she would start to see the complex web of factors that contributed to his behavior. She might see the neglect and discrimination he faced as a werewolf, which could make her feel a bit of pity. However, she would still firmly oppose his cruel actions and try to find a way to either contain or reform him, all while being acutely aware of the danger he poses.
There's a fanfiction called 'Greyback's Redemption Arc'. In it, Fenrir Greyback saves Hermione from a group of Death Eaters. The author might have written it to explore the idea of redemption for a character like Greyback. Maybe he saves Hermione because he sees her as a symbol of the good in the wizarding world that he has lost touch with, and this act of saving her could be the start of his journey towards redemption.
In one fanfiction concept, Greyback saves Hermione when she is trapped in a magical maze created by dark wizards. Greyback, being a cunning and experienced dark creature, is able to navigate the maze and get to Hermione before the maze collapses or she is killed by the various traps inside. He might save her because he senses that she has a great potential that could be useful to him in the future.
Fenrir might be intrigued by Hermione fanfiction because Hermione is a very intelligent and powerful character. Fanfictions often explore her potential in new and exciting ways, like her delving into different branches of magic or having unique adventures. This would be interesting to Fenrir as he may be curious about how she uses her wits and magic in these alternate scenarios.
Another theme is the idea of redemption. Many fanfictions explore whether Fenrir can be redeemed through his interactions with Hermione. It's about whether love or friendship can change a character who has been on the wrong path for so long.
