The 'enemies to lovers' trope can also be found. Maybe Logan initially dislikes Remus' unruly behavior, but over time, they develop feelings for each other. There's also the 'roommate' or 'forced proximity' trope, which can lead to all kinds of interesting interactions and relationship developments between them.
A common trope is the 'intellectual connection'. Hermione is very intelligent, and Remus is well - read and knowledgeable. Fanfictions often explore how they bond over books, spells, or complex magical theories. Also, the 'healing each other' trope is quite popular. Hermione can help Remus deal with his lycanthropy - related insecurities, while Remus can support Hermione through her academic or personal struggles.
One popular trope is the 'fish out of water' situation. Hermione is from a different time, so she has to adapt to the past when she travels back to Remus' time. This leads to some really interesting situations like her trying to hide her modern knowledge. Another is the 'forbidden love' trope as there are many barriers to their relationship, such as the time difference and Remus' lycanthropy.
There's also the 'soulmates' trope. Some fanfictions depict Remus and Sirius as soulmates, with a special connection that goes beyond the normal. This can be a magical bond or just a really deep emotional connection. And then there's the 'reunion' trope. After being separated, for example, when Sirius was in Azkaban, fanfictions often focus on their emotional reunion and how they pick up their relationship from there.
The 'time - travel' trope is also common. As I mentioned before, it can be really interesting to see them go back in time and interact with the younger versions of themselves or other characters. It often leads to a lot of plot twists and revelations.
The 'alternate universe' trope is also common. In some fanfictions, the story might be set in a world where the normal rules of the Harry Potter universe don't apply. For example, there could be a world where age differences don't matter as much, or where Remus and Hermione are brought together in a different context, like they are on a secret mission together and their relationship blossoms during that time. There are also stories that might involve time - travel, where Hermione goes back in time and meets a younger Remus, which adds another layer of complexity to their relationship.
One popular trope is the 'new in town' trope. The reader character is new to Derry, and then they meet the Losers' Club or Pennywise. It sets up a great scenario for character interactions. For example, the reader might be intrigued by the strange happenings in town and get drawn into the story.
Fanfiction.net might also be a place to look. However, the tagging system there might not be as precise as AO3. But still, with some patience in browsing and using the search function, you could come across some Logan x Remus fanfictions.
Another theme is friendship - turned - love. Since they were friends in the original story, fanfictions might show how their platonic relationship gradually evolves into a romantic one. This could involve them realizing their feelings during their time at Hogwarts, perhaps through shared experiences like studying for exams or facing a common enemy.
One popular trope is the 'Powerless AU' where members of the Justice League are without their powers. It adds an interesting dynamic as they have to rely on other skills. Another is the 'Secret Identity Reveal' trope, which always creates a lot of drama and character development.
One common trope is the 'Forbidden Love' trope. Given Remus's age and his status as one of Harry's teachers, a relationship with Hermione would be considered inappropriate in the eyes of many in the wizarding world. This adds a layer of tension and drama to the story.
