Well, a plot twist might be that Naruto discovers Anko has a hidden power that she's been suppressing. This power could be related to a rare bloodline or a forbidden jutsu. As they start dating, Naruto notices strange occurrences around Anko and eventually uncovers this secret. This could create a rift between them as Naruto might be worried about the implications of such a power, while Anko is afraid of being rejected because of it. Also, there could be a plot twist where the Akatsuki targets Anko because of her relationship with Naruto. They might see her as a way to get to Naruto and try to kidnap or manipulate her.
One possible plot twist could be that Anko has a hidden power that Naruto uncovers during the adoption process. Maybe she has a connection to an ancient clan or a special jutsu that she's been suppressing. This discovery could change Naruto's view of her and also put them in danger as others might be after that power.
A plot twist could be that Naruto discovers a secret about Tsunade that she has been hiding all along. It could be something related to her family or a power she has been suppressing. This discovery could either strengthen their relationship or create a rift between them. Also, there could be a twist where an outside force tries to use their relationship to gain power in the ninja world. They might try to manipulate Naruto or Tsunade to their advantage.
A plot twist might be that their dating is part of a prophecy. In the ninja world, prophecies are common in fanfictions. They could find out that their relationship is destined to either save the village or destroy it. This would put a huge strain on their relationship as they have to decide whether to follow their hearts or try to avoid the prophecy. And on top of that, there could be a misunderstanding where Naruto is framed for something bad, and Tenten has to decide whether to believe him or not.
One possible plot twist could be that their respective villages oppose their relationship at first. Since Naruto is from Konoha and Temari is from Suna, the political situation between the villages might make their relationship difficult. For example, there could be old treaties or grudges that get in the way. Another plot twist could be the interference of a third party who has feelings for either Naruto or Temari. This person could try to create misunderstandings between them to break them up. Also, a plot twist might be that Naruto has to go on a long and dangerous mission right when their relationship is starting to develop, leaving Temari worried and uncertain about their future together.
One possible plot twist could be that Naruto discovers some hidden power within himself related to his connection with Anko. Maybe it's a special jutsu that only their family line can use. This discovery could lead him on a new journey to master this power and uncover the secrets of their family's past.
In a more complex plot, Anko could be initially hesitant to date Naruto because of their age difference or her past traumas. But Naruto, with his determination, tries to break through her barriers and they gradually fall in love as they face various challenges together, like dealing with village politics and enemy attacks that put their relationship to the test.
One possible plot twist could be that Anko's unorthodox training methods lead Naruto to develop a unique fighting style early on. For example, he might learn some of Anko's snake - related jutsu and combine them with his own shadow clone technique in unexpected ways. This could make him stand out even more among his peers and draw both admiration and envy.
One possible plot twist could be that Anko discovers the baby Naruto has some unique and unexpected powers right from birth. Maybe powers that are not shown in the original Naruto story. For example, he could have an instant connection to snakes like Anko, which could lead to a whole new arc in the fanfiction about him learning to control this power and how it affects his relationship with others in the Hidden Leaf Village.
Often, a plot point is Anko's past traumas and how Naruto helps her heal. For example, her experiences with Orochimaru. Naruto's kind heart and his own experiences of being an outcast in a way allow him to understand her pain. This mutual understanding can be a strong bond in the relationship.
One possible plot twist could be that Aphrodite's powers of love start to have unexpected effects on Percy. For example, instead of making him fall for her in the typical way, it makes him see love in a completely different light, like seeing the love between friends more intensely. This could lead to a conflict as Aphrodite expected a more romantic outcome. Another twist could be that the other gods get jealous of their relationship. Since Aphrodite is the goddess of love, her dating Percy might make other gods feel left out or threatened. This could cause them to try and break the two apart, creating all sorts of challenges for Percy and Aphrodite.
