One popular trope is the 'opposites attract'. Ron is often seen as more of a hot - headed and impulsive character, while Theodore might be depicted as more reserved. Their differences can create interesting dynamics in the stories.
Another trope could be the 'redemption' story. Theodore might be written as a character who is trying to break away from his Slytherin - associated 'dark' tendencies, and Ron could be the one who helps him through that process, leading to a deep emotional connection between them.
One popular trope is the 'friends - to - lovers' trope. Given their pre - existing relationship as brothers in the original, it's interesting to see how writers develop their relationship into something more romantic. Another could be the 'hurt/comfort' trope, where one of them gets into trouble or is hurt, and the other is there to comfort and support.
The 'enemies - to - lovers' trope is also quite common. They could start off not getting along, maybe due to misunderstandings or differences in their personalities or beliefs. But as the story progresses, they gradually fall in love. For example, Bonnie might initially think Ron is too brash, and Ron might think Bonnie is too reserved, but then they discover the good in each other.
The 'saving each other' trope is also quite common. Maybe Ron saves Linka from a dangerous situation, or vice versa, which then deepens their connection. Additionally, the 'hidden feelings' trope, where they both have feelings for each other but are too shy or afraid to admit it at first, can add a lot of tension and drama to the story. There could also be the 'alternate universe' trope, where the story is set in a different world or time period, allowing for new and creative interpretations of their relationship.
The 'danger - and - rescue' trope is also quite prevalent. Ron often gets into trouble in the show, and in fanfictions, this can be exaggerated. Kim then has to rescue him, which can lead to some intense and romantic moments between them.
You can try fanfiction websites like Archive of Our Own (AO3). There are a large number of fanfictions there, and you can search for 'ron x theodore' specifically. Many authors post their works there, covering various themes and storylines.
The 'secret kiss' trope is also quite common. Maybe they have to keep their relationship a secret for some reason, like family drama or Hogwarts rules. It adds an element of mystery and excitement to the story. And then there's the 'angsty kiss', where there have been misunderstandings or fights between them before the kiss, which makes the moment even more intense.
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.
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.
There's also the 'soulmate' trope where they are fated to be together in some way. It could be a mark on their body that only the other can see, or a feeling that they are meant for each other from the start. This trope gives a sense of destiny to their relationship in the fanfiction.
Well, a frequently used trope is the 'culture clash' between trolls and humans. Trolls may have their own languages, traditions, and values that are very different from humans. This can create misunderstandings at first but also opportunities for growth and connection. Additionally, the 'protector' trope is often used, where either the troll protects the human or vice versa in dangerous situations.
