In such fanfictions, a common plot device is the cultural clash between the two worlds. Naruto comes from a ninja - based society, and Trunks from a world of Saiyans and advanced technology. Their brotherhood could be used to bridge these two cultures. For example, they might introduce ninja techniques to the Dragon Ball world or vice versa. There could also be a plot device where they have to work together to save both of their universes from a common threat, which emphasizes their brotherly bond and the importance of their combined abilities.
A typical plot device could be a power - up related to their brotherhood. Since Naruto has his chakra and Trunks has his Saiyan strength, they might discover a new combined power because they are brothers. Also, there could be a time - travel element involved. Trunks is associated with time travel in Dragon Ball, and this could be used in the fanfiction to explain how Naruto and Trunks' relationship came to be. For instance, Trunks could travel to the Naruto universe and somehow become related to Naruto through some time - warped event.
In many such fanfictions, the power struggle plot device is used. If Sakura becomes too powerful or tries to assert her dominance in a way that overshadows Naruto and Hinata's relationship or their own achievements, they might start to hate her. For example, if Sakura gets a high - ranking position in the village and starts making decisions that affect Naruto and Hinata negatively, it can fuel their dislike. Another aspect is the character arc plot device. The writer might give Sakura a negative character arc where she becomes more self - centered or greedy, which would make Naruto and Hinata dislike her.
Another plot device is the use of unique Mist village jutsu and traditions. Naruto often has to learn about these in order to navigate the village and rescue the clans. For instance, he might have to understand the significance of certain water - based jutsu or the cultural taboos that could either help or hinder his mission.
One common plot device is mind control. For example, Voldemort or some other dark force could control Harry's mind and make him kill Dumbledore without his full awareness. Another is a misinterpreted prophecy. Harry might think Dumbledore is endangering his life based on a wrongly understood prophecy.
Flashbacks are also a common plot device. The fanfic could show flashbacks of Naruto's past, especially related to his early encounters with the Nine - Tails. These flashbacks could give him insights into how to control the beast. Moreover, the concept of a spiritual connection or a bond with a previous Nine - Tails host could be explored. This connection could transfer knowledge or power to Naruto, enabling him to achieve complete control.
Another plot device could be a mind - link or a shared vision. Maybe Naruto has a moment where he links minds with a past Hokage who was an expert in Rasengan. Through this connection, he gains instant knowledge on how to form and use it. It's a more supernatural way of learning compared to the traditional training.
One popular plot device is the power - up. Naruto might gain a new form or a super - powerful jutsu right before facing an Akatsuki member. Another is the betrayal within the Akatsuki. For example, someone in the Akatsuki might give Naruto information to help him in the fight. And the 'damsel in distress' can also be used, like Naruto has to save a friend from an Akatsuki member, which leads to the fight and the kill.
A frequent plot device is the idea of a power struggle. Percy might be in a situation where he has to fight off other forces that want to take advantage of his weakened state while he's holding up the sky. This could involve battles with mythical creatures or other malevolent demigods. Another common device is the exploration of Percy's heritage. Maybe while under this great strain, he discovers some long - lost aspect of his family history that gives him the strength to keep going. Also, time manipulation is sometimes used. The time Percy spends holding up the sky might be different in the mortal world compared to the demigod world, which creates interesting plot twists.
In these fanfictions, a common plot device is the cultural exchange. Hermione could introduce Edward to things like Butterbeer and magical games, while Edward could show Hermione the beauty of the vampire world at night. There's also the plot device of identity crisis. Hermione might question her place in the wizarding world if she falls in love with a vampire, and Edward might wonder how he fits into Hermione's world. And sometimes, there's the plot device of a prophecy or a magical bond that ties them together, which forces them to be together despite all the odds and difficulties from their different backgrounds.
One common plot device is the love triangle. It creates drama as Sakura may be jealous of Hinata's relationship with Naruto. Another is the redemption arc for Naruto's feelings. Maybe he used to be confused about his feelings for Sakura but then realizes his true love is Hinata. And there could be a friendship break - up plot device where Naruto distances himself from Sakura due to his newfound love for Hinata.
One common plot device is Sakura setting up 'accidental' meetings. For example, she might make it seem like Naruto and Hinata just happen to be at the same place at the same time, like at a local festival. This gives them an opportunity to interact without it feeling too forced.
