A very popular plot device is the misuse of natural energy. Some fanfictions show characters trying to use natural energy in ways that go against the natural order. This often leads to negative consequences, such as the character losing control or attracting dangerous enemies. It creates a lot of drama and conflict in the story. For example, a character might try to absorb too much natural energy too quickly, which causes them to go berserk.
One common plot device is the discovery of a new source of natural energy. In fanfictions, a character might stumble upon a hidden place filled with concentrated natural energy. This discovery then sets off a chain of events, like other characters trying to take over the place or the finder having to protect it.
A common plot device is using the Body Flicker for a surprise attack. The character seems to disappear and then suddenly reappears right next to the enemy. Another is using it to escape from dangerous situations quickly. For example, when a character is surrounded by foes, they use the Body Flicker to vanish into the forest.
One common plot device is that Naruto has to adapt to the new magical rules of the Negima world. Another is that he might be on a quest to find a way to transfer his immortality or use it to save the Negima world from a great threat.
The glowing eyes could also be used as a way to attract the attention of a mysterious character. Maybe there's a powerful and reclusive ninja who is intrigued by Naruto's glowing eyes. This character then becomes either a mentor or an antagonist to Naruto, depending on their motives. It adds an element of mystery and new relationships to the fanfiction.
One common plot device is Fem Merlin being a time - traveler. She could come from the past or future to change certain events in the Harry Potter timeline. This can create a lot of interesting scenarios where she has to adapt to the modern wizarding world while also trying to achieve her mission.
Another plot device could be Thalia's submissive behavior in a romantic relationship. Perhaps she falls for someone who has a dominant personality, and her submissiveness in that relationship creates interesting relationship dynamics, like having to compromise more than she's used to.
The Moka model in Rosario + Vampire fanfiction often has plot devices centered around her powers. For instance, she might lose her powers temporarily, which forces her to rely on her wits and the help of her friends. This can lead to character growth and new relationships forming. Another plot device is her being targeted by other vampires or dark forces because of her unique bloodline. This creates a sense of danger and suspense in the fanfiction. Moreover, the idea of Moka having to make a choice between her vampire life and a more human - like existence is also a common plot device. It allows for exploration of themes like identity and self - discovery.
One common plot device is Azari being a long - lost heir. He might be the key to some ancient prophecy that could save or destroy Wakanda. Another is Azari having a special power that he has to learn to control. For example, a power that is linked to the heart - shaped herb in a new and unexpected way.
One common plot twist could be that Naruto is initially underestimated by the DxD characters. They see him as just another outsider, but then he reveals his godlike powers and completely turns the tables. For example, in a battle situation where the devils think they have the upper hand, Naruto unleashes a new form of his chakra that astonishes everyone.
One common plot device is the use of Naruto's friends to help him. For example, Shikamaru might come up with a brilliant plan to deceive those arranging the marriage. Another is Naruto's own unique ninja abilities. He could use his shadow clone jutsu to create distractions. Also, there might be a secret enemy behind the arranged marriage that Naruto discovers during his attempts to escape, which adds an element of mystery.
Training with a powerful mentor is a common plot device. For example, in many fanfictions, Naruto might train with an ancient sage or a long - lost relative who has powerful techniques to pass on. Another is the discovery of a hidden power or ability. This could be something like a new form of chakra or a long - forgotten jutsu.
