One plot point could be Naruto facing opposition from those who don't want him to claim his rightful place as the lost prince. They might try to undermine him at every turn, which adds a lot of conflict to the story. And there could also be a sub - plot about Naruto trying to reunite his long - lost family members.
One interesting plot point could be Naruto's struggle to fully understand and communicate with the Kyubbi. It's not just about using its power, but really having a connection with it on a deeper level.
The discovery of hidden feelings. When drunk, Naruto or Sakura might accidentally reveal their true feelings for each other. Maybe Naruto has always had a deeper love for Sakura than he let on, and in his drunken state, he confesses. Or Sakura, who has always seen Naruto as a friend, realizes that there is more to her feelings when she's drunk. This could be the start of a new chapter in their relationship.
Perhaps a key plot point is when fem Naruto uses her mermaid abilities to save the village. Since mermaids are often associated with water, she could control a massive flood or something water - related that was threatening the village. And also, the reactions of the other characters, like Sasuke or Sakura, when they find out about her being a mermaid would be really interesting.
One interesting plot point could be how Naruto, now in Shikamaru's body, uses his newfound intelligence in a different way. He might strategize battles more like Shikamaru but with his own Naruto - like determination. For example, in a fight against a powerful enemy, he could combine Shikamaru's shadow jutsu with Naruto's never - give - up attitude to outwit the foe.
One interesting plot point could be the different relationships between characters in the future. For example, how Naruto's friendships might have evolved or changed over time. Maybe his bond with Sasuke has deepened in unexpected ways. Another could be new ninja techniques that are introduced, which might be a result of the characters' continuous growth and innovation in the fanfiction world.
One interesting plot point could be Naruto's reunion with his old friends. He might share his new experiences and skills, like new jutsu he learned during his time away. Another could be how the village has changed in his absence, with new buildings or new generations of ninjas emerging.
In this type of fanfiction, a great plot point is Naruto's transformation. He might break the limits of his physical form, evolving into a more powerful and unique state. This could be something like a combination of his Sage Mode and Nine - Tails Chakra Mode into an all - new, never - seen - before mode. It could also include him breaking the limits of his knowledge, learning ancient and forbidden ninjutsu that gives him an edge in battles against extremely powerful opponents.
One interesting plot point could be Naruto using new and unexpected jutsus. Maybe he combines different techniques he's learned in a creative way to fight Orochimaru. For example, he might blend his Rasengan with some Sage Mode abilities in a way he hasn't done in the original series.
In this fanfiction, perhaps an interesting plot point is the discovery of the reason behind Naruto being sealed in time. It might be related to some ancient prophecy or a powerful enemy's plot. Also, the development of new characters who are affected by Naruto's absence in time could be really engaging.
One interesting plot point could be Naruto having an even more enhanced connection with the bijuu, allowing him to access new and powerful forms. For example, he might be able to combine the powers of all the bijuu in a unique way that no one has ever seen before.
