Some fanfictions in the Twilight Mermaid genre use the trope of transformation. Maybe the mermaid has the ability to transform into a more human - like form that can better interact with the Twilight characters. There's also the trope of the mermaid being a key to solving a big problem in the Twilight world, like a threat from another supernatural force. Her mermaid powers could be the solution, which makes her an important figure in the story despite being an outsider.
One popular trope is the mermaid's struggle to fit into the Twilight world. Since the Twilight series has its own set of rules about vampires and werewolves, a mermaid character often has to find her place among them. Another is the love triangle, which is a staple in Twilight. A mermaid might find herself in love with a vampire or a werewolf, creating a complex romantic situation. And the idea of the mermaid having some sort of special power that is unique to her mermaid nature but also relevant in the Twilight universe, like being able to communicate with sea creatures and using that to help the Twilight characters in some way.
One popular trope is the 'forbidden love' aspect. Since Twilight has different species like vampires and werewolves, a relationship between a human reader and one of these non - human characters can be seen as forbidden. Another is the 'fated mates' trope, where the characters are destined to be together. It adds an element of inevitability to the relationship.
In Twilight Emmett x OC fanfiction, the 'power imbalance' trope can be seen. Emmett has all the powers and immortality of a vampire, while the OC is a frail human. This creates an interesting dynamic. There's also the 'cultural clash' trope. The vampire culture in Twilight is very different from human culture. The OC has to adapt to things like vampire traditions, hunting habits, and their view on human life. And don't forget the 'redemption' trope. Maybe Emmett has some past actions he needs to make up for through his relationship with the OC.
One popular trope is the mermaid falling in love with a human. It's a classic. Another is the mermaid having a special power in her tail, like the ability to heal or control the sea. And of course, the mermaid being out of her element on land and having to adapt is also quite common.
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 popular trope is the 'new girl in Forks' where the reader - insert character is a new arrival in town and catches the attention of the Twilight characters. Another is the 'human - turned - vampire' scenario where the reader - insert experiences the transformation. And of course, the 'love triangle' trope is quite common, often involving the reader - insert, Edward, and Jacob.
One common trope is the discovery of unique abilities. For example, the reincarnated wolf might find it can communicate with other animals in a special way, which helps it survive and thrive in the new world. Another trope is the formation of a pack. The wolf protagonist often gathers other animals or even other reincarnated beings to form a unique community. And of course, there's the struggle against human encroachment, as the wolf tries to protect its territory from humans who don't understand its new - found intelligence and abilities.
In many of these fanfictions, the 'discovery' trope is often used. It's about how they first find out about the pregnancy. It could be a shock, or there could be some signs that they initially misinterpret. And then there's the 'adaptation' trope. They have to adapt to the physical and emotional changes that come with the pregnancy, which is not easy given their vampire and werewolf natures.
In King Sombra and Twilight fanfiction, a common trope is the 'Forbidden Friendship'. Given King Sombra's dark nature, a friendship with Twilight would be seen as something not supposed to happen. It creates an interesting dynamic as they both come from very different worlds. Also, the 'Teaching' trope is often used. Twilight, with her vast knowledge, might try to teach King Sombra about the values of friendship and kindness. And finally, the 'Danger' trope, where King Sombra's presence always poses a threat to Twilight and her friends, leading to many tense situations in the fanfiction.
A common trope is the 'underwater adventure' trope. The fanfiction often takes Marinette on exciting adventures underwater. She might explore lost underwater cities, find hidden treasures, or encounter ancient sea monsters. This allows for a lot of world - building and showcases the beauty and danger of the underwater world. Also, the 'fish - out - of - water' (pun intended) trope is used when Marinette has to adjust to her new mermaid form and the underwater lifestyle.
The 'rivalry' trope can be interesting in fem Clark Kent fanfiction. She could have a female rival who challenges her not just in terms of power but also in how society views them as women. The 'mentor - mentee' relationship is another. Maybe she has a female mentor who guides her on how to be a strong female superhero. And the 'legacy' trope, where she has to live up to the name of Clark Kent in a new, female - centric way.
