Well, one trope could be that you are transported into the Twilight fanfiction as an out - of - place character, like a modern - day person in a world that seems stuck in a different era. You might introduce new technology or ideas that disrupt the normal flow of the Twilight world. There's also the possibility of being a shapeshifter that is different from the werewolves in the story, which then creates a whole new dynamic with the existing supernatural beings.
A typical trope is the epic quest. In many transported to fantasy world stories, the hero is given a task or a quest that they must undertake. This could be to defeat an evil sorcerer or to find a magical artifact. Also, there's the idea of the chosen one. The character is somehow fated to be in the fantasy world and has a special destiny, like Harry Potter. He was the only one who could defeat Voldemort. Another common thing is the existence of magical creatures. From dragons to unicorns, these creatures add to the wonder and danger of the fantasy world.
An interesting character in this context could be created by making them a bit of an enigma. For instance, they could have a power that they don't fully understand themselves at first. Their values can also be different from the characters in the Twilight world. They might value knowledge above all else in a world that seems to be driven by power and passion. Also, you can make them have a secret past that gradually unfolds as the story progresses, making other characters and the readers constantly curious about them.
One common trope is the sudden acquisition of special abilities. The protagonist, upon being transported to the game world, often gains unique powers that help them survive and thrive. Another is the encounter with various in - game races and forming alliances or rivalries. For example, they might meet elves, dwarves, or goblins. Also, there's usually a quest or a mission that the protagonist has to undertake, which drives the plot forward.
One common trope is the OC being a new student or outsider in the fanfiction world. For example, in a Harry Potter fanfic, an OC might be a transfer student to Hogwarts. Another is the OC having a special power or ability that sets them apart. They could be the only one who can communicate with a certain magical creature. Also, the OC might become a love interest for a canon character, like an OC falling in love with Sherlock Holmes in a Sherlock fanfiction.
One idea could be arriving in Gravity Falls right during the Weirdmageddon event. You could team up with the Pines family to fight Bill Cipher. Another could be getting transported into the past of Gravity Falls, like when the town was first founded, and uncovering long - lost secrets. Maybe you become a new character in the Mystery Shack and have to deal with the daily weirdness that comes with it.
One common element is encountering strange and otherworldly creatures. In supernatural fanfiction, you might come across vampires, werewolves, or demons. Another element could be the discovery of hidden powers within oneself. For example, the reader - turned - character might find out they can control elements like fire or water. Also, there are often complex and mysterious settings, such as an ancient, haunted castle or a fog - covered forest filled with magic.
One common trope is the 'alternate universe' where the Avengers have different backstories or relationships. For example, a fanfic might explore what if Tony Stark was raised by the Asgardians. Another is the 'romantic subplot' like a love story between Steve Rogers and Natasha Romanoff which wasn't really explored in the movies. And there's often the 'new recruit' trope where an original character is added to the Avengers team, bringing in new dynamics and storylines.
One popular trope is the 'What if' scenarios. For example, what if Bella had chosen Jacob instead of Edward? Another is the 'alternate universe' concept, where the characters are in different settings like a modern-day high - tech world or a historical period. And the 'character backstory expansion' is also common, like delving deeper into Rosalie's past before she became a vampire.
One common trope is over - protectiveness. Naruto might be extremely protective of Sakura, and vice versa. Another is shared family secrets that only they know. It adds an element of mystery to the story.
A common trope is the twin having a different supernatural ability. For example, she might be able to control the elements while Bella has her mind - shield. Another is the love triangle, but instead of Edward - Jacob - Bella, it's between different characters involving the twin. Often, the twin also has a secret she's keeping from Bella which drives the plot.
