A very common plot device is the exploration of their pasts. Fanfic authors might dig into Nagato's past and find some hidden link to Naruto's past. For instance, they could discover that their families were somehow connected long ago. This discovery then forms the basis of their relationship in the fanfiction. It gives a sense of destiny and inevitability to their connection, as if they were always meant to cross paths and influence each other.
Often in fanfiction, Naruto's positive influence on Nagato is emphasized. Nagato's actions were driven by his past traumas, but Naruto's unwavering belief in peace can make Nagato reevaluate his views. Their relationship is a great source of exploration for fanfiction writers, as it combines elements of redemption, friendship, and the clash of two different worldviews.
A common plot device is the influence of dark magic. If Percy is exposed to some form of dark magic, it could slowly corrupt his mind and soul. For instance, a cursed object that he comes into contact with might start to change his personality, making him more selfish and cruel.
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 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.
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.
A plot device often used is the 'redemption arc' for Rodolphus. Maybe he starts to question his Death Eater ways because of Hermione. He could show some kindness or vulnerability that Hermione is attracted to. Also, the 'fish out of water' situation can be used. For instance, if Rodolphus is forced to work with Hermione in a non - Death Eater context, like in a magical research project, and their relationship blossoms from there.
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.
The use of alternate universes is also popular. In an alternate universe, Supergirl could have different powers or a different personality, and the same goes for Doomsday. This allows for unique and unexpected storylines where the outcome of their battle is completely different from the mainstream comics or shows.
A third common plot device is the idea of redemption. Hades may be seen as a 'villain' at first for kidnapping Persephone, but as the story progresses, he tries to make amends. He could show her kindness, protect her from other underworld threats, and in doing so, Persephone begins to see him in a different light. This allows for a more in - depth exploration of their characters and their relationship.
Often in these fanfictions, a plot device is the existence of an alternate dimension. The Avengers could find a way to access this dimension where things didn't go wrong and bring back the good elements from there to fix their own world. Additionally, a Deus ex Machina - like event, such as a sudden, unexplained cosmic force that restores everything to normal, is sometimes used. However, this can be a less satisfying device as it doesn't really involve the characters' efforts as much. Another plot device is the power of teamwork being magnified to an extreme degree. The Avengers, by working together in a more perfect way than in the original story, are able to fix all the problems.
