Perhaps Benjamin and Tia find themselves in an alternate dimension within the Twilight universe. In this dimension, they have to face their greatest fears and insecurities. As they work through these challenges, they grow closer and form a stronger bond than ever before. This could lead to a new level of understanding between their two characters.
Their relationship could be developed uniquely by having them communicate through a special form of magic that only they share. This magic could be tied to their emotions, so when they're happy, it creates beautiful glows, and when they're sad, it sends out a signal that only the other can understand.
Another option is to write a fanfiction about their professional lives. If they are in a certain field in the story, like Tia and Benjamin are both artists, you can write about how they collaborate, compete, and inspire each other in their art. It's a positive and creative way to write about them.
Writing fanfiction that involves sexual content is generally not appropriate. It goes against ethical and moral norms, especially if it involves real or fictional characters in a vulgar way. Fanfiction should focus on positive aspects like character development, new storylines within the bounds of decency.
Another type of main character in these fanfictions could be a human who becomes intertwined with Benjamin's life. This human might be in a dangerous situation that only Benjamin can save them from, or they could be someone who has an unexpected bond with Benjamin. This creates a lot of drama and interesting plotlines as the relationship between the human and Benjamin develops, often against the backdrop of the vampire - human relations in the Twilight world.
The setting also plays a big role. Since Benjamin Twilight is often in a fantastical world, the description of that world, its rules, and its inhabitants can make or break a fanfiction. Writers need to create a vivid and believable world for the story to be engaging.
The relationship between them is also a major element. They are both vampires in the Twilight world, but they come from different backgrounds. Their friendship or alliance often forms the core of the story. Sometimes they start off as strangers and gradually build trust, and other times they are old friends facing new challenges together. In some fanfictions, they also have to deal with the politics among the vampire clans, which adds another layer to their relationship.
One key element is the relationship exploration. Since Bella is from the main Twilight storyline and Benjamin is a character with unique abilities, their relationship, whether it's friendship or something more romantic, is often at the center. For example, how they interact with each other's powers and personalities.
One popular Twilight Benjamin fanfiction might be those that explore Benjamin's backstory. For example, a story could delve into his life before becoming a vampire and how he came to be in the vampire world. It might also focus on his relationships with other characters from the Twilight series, like his interactions with the Volturi.
The setting within the Twilight universe is another important element. Fanfictions usually incorporate the existing lore, such as the different vampire covens and their rules. This provides a familiar backdrop against which the story of Benjamin and his mate unfolds, and it also gives the author the opportunity to expand on the established world in new and interesting ways.
