Another popular trope is the power - up or skill exchange. Imagine a character from Harry Potter learning the combat skills of the characters in Final Fantasy 13. Or a Final Fantasy 13 character learning how to cast spells like a wizard. This trope often leads to some really cool and unexpected battle scenes in the fanfiction.
Another well - liked trope is the 'romance across universes'. Fans love to pair characters from Harry Potter and Final Fantasy 15 together. It could be something like Hermione and Prompto falling in love. This trope adds an element of the unknown and often creates very emotional and unique stories.
In 20 years of Harry Potter fanfiction, there are several popular tropes. The 'Powerful!Harry' trope is quite common. Fans like to write about Harry having even more power than in the books. Also, the 'Soulmate' trope is popular, especially when it comes to romantic pairings. And the 'Dark!Hermione' trope has emerged, where Hermione takes a more morally ambiguous or even dark path, which is an interesting twist on her character.
The 'Power Transfer' trope is often seen. This is when a character from one series gains the power or ability from the other series. Say, Harry getting the ability to see ghosts like Sam does in Supernatural. And then there's the 'Shared Enemy' trope. A threat that is dangerous to both the wizarding world and the Supernatural world forces the characters to cooperate, creating exciting storylines.
A very common trope is the 'Dark!Harry' concept. In these stories, Harry turns to the dark side, either because of being mistreated or for some other reason. It's interesting to see how the story unfolds when the main hero becomes an anti - hero. Also, the 'Teacher - Student Romance' trope exists, though it's a bit controversial. But it does add an element of forbidden love to the stories.
One popular trope is the 'alternate universe' where the story takes place in a different setting or with different rules from the original series. For example, a wizarding world where Voldemort never existed. Another is the 'character redemption' trope, like Draco Malfoy getting a chance to be a good person from the start. And 'romantic pairings' that fans love to explore, such as Hermione with someone other than Ron.
One common trope is the 'fish out of water' situation where Castiel is suddenly in the Harry Potter world and has to figure out how things work. Another is the 'powerful ally' trope where he becomes a crucial help to Harry and his friends.
The fish - out - - of - water trope is also common. Picture Naruto and Garra suddenly finding themselves in the world of Final Fantasy 7. They have to adapt to the new environment, different cultures, and strange magic systems. This often leads to humorous and interesting situations as they try to figure out things like chocobos and materia. Another trope is the team - up trope. Naruto and Garra form an alliance with some of the Final Fantasy 7 characters to fight a common enemy, like a powerful villain that threatens both their worlds.
One popular trope is the 'Fish out of Water' story. For example, a character from Naruto suddenly finds themselves in the world of Final Fantasy XV or vice versa. This allows for a lot of exploration of the differences between the two universes, like the magic systems or the social structures. Another common trope is the 'Power - Up' trope. A character might gain new abilities from the other universe, like a Naruto character learning some of the unique combat skills from Final Fantasy XV.
One popular trope is the 'Older Brother Figure'. Bill often takes on this role for Harry in fanfiction. For example, in many stories he gives Harry advice on dealing with Voldemort. Another is the 'Mysterious Curse - Breaker' trope. Since Bill is a curse - breaker, fics often play up the mystery and danger of his job. A third popular trope is 'Weasley Family Bonds'. Fanfictions explore how Bill's actions and decisions affect the whole Weasley family.
One popular trope is the 'new student at Hogwarts' where the main character, often an original creation, enters the school and has to navigate the complex social and magical world. Another is the 'discovering a hidden power' trope, like finding out they can communicate with magical creatures in a unique way. And of course, the 'romance between houses' trope, such as a Hufflepuff falling in love with a Ravenclaw, which adds an interesting dynamic to the story.
