In crossover fanfics where one becomes a villain, what are the common tropes and plot devices?

One common plot device is that Naruto is able to unlock new and powerful forms or jutsus because of his potent chakra. For example, he might develop a unique transformation that only his large chakra reserve can sustain. Another is that he becomes a target for powerful villains who want to either steal his chakra or use him for their own purposes.

One common trope is the 'fish - out - of - water' situation. For example, when the characters from Supernatural first arrive in Mystic Falls, they are confused by the different rules of the vampire society there compared to the monsters they usually hunt. Another trope is the 'power - struggle'. This could be between the powerful vampires like the Originals in Vampire Diaries and the angels or demons from Supernatural. They often have to compete or cooperate depending on the situation in the fanfic.

One common plot device is Billy's struggle with his dual identity. He has to keep his identity as Billy Batson a secret while being a part of the Young Justice team as Shazam. Another is his power development. Writers often explore how he gets better at using his powers over time. Also, his relationships with the other team members can be a plot device, like when there are conflicts or when they team up to fight a common enemy.

One common plot device is the revelation of hidden powers. When a blood binding is involved, often characters discover new and unexpected magical abilities that are tied to the bond. For example, they might be able to communicate telepathically or share magic in unique ways.

One common plot device is Draco flirting with other girls in front of Hermione. For example, he might shower another girl with compliments about her magical abilities which Hermione takes as a personal slight since she prides herself on her own skills. This immediately makes her jealous and sparks a series of events where she tries to show Draco that she doesn't care, but actually does.

Well, 'Hidden Potential' is a big trope. A Senju character in fanfics may seem ordinary at first but then discovers they have some amazing hidden potential within them related to their Senju heritage. 'Senju and the Tailed Beasts' is also common. Fanfics might explore how a Senju could potentially bond with or control a tailed beast in a way different from what we've seen in the original Naruto story. There's also the 'Ancient Prophecy' trope, where a Senju is part of an ancient prophecy that dictates their actions and the future of the Naruto world.

One common trope could be the complex character development of the villain. In many such novels, the villain is not just pure evil but has a backstory that led them to their actions. Another trope might be the power struggle. The villain often has to compete with the hero or other antagonists for power, influence, or resources. Also, there could be the trope of redemption or self - realization, where the villain starts to question their own actions and motives as the story progresses.

Some common tropes in villain oc fanfiction include the 'seductive villain' trope. This is when the villain uses their charm or attractiveness to manipulate others. It can add an interesting dynamic to the story. The 'vengeful villain' trope is also quite common. They are seeking revenge for some past wrong done to them. And then there's the 'evil legacy' trope. The villain oc is following in the footsteps of an even greater evil from the past, and they are trying to live up to that reputation or complete some unfinished evil business.

One common plot device is time - travel. A character might go back in time to change the events that led to Planet Vegeta's destruction. Another is the appearance of a new, powerful ally who saves the planet from Frieza. For example, an ancient Saiyan spirit might awaken and possess a Saiyan, giving them the power to defeat Frieza and protect the planet.

One common plot device is his relationship with the Dark Lord. Often, in these fanfics, Voldemort will punish Lucius for his failures, which leads to his whump. For example, he might be tortured or stripped of his powers.
