Well, when it comes to Naruto time travel and Rinnegan in fanfics, it's often about exploring new storylines. Maybe Naruto himself gets the Rinnegan and travels back in time to train his younger self. This would make him a much more powerful ninja at an earlier stage and could completely change the power balance in the Hidden Leaf Village and among the other ninja villages as well.
Maybe Kurama, the nine - tailed fox inside Naruto, could be an unexpected ally in a new way. Since they have a bond, Kurama could provide Naruto with extra power and insights when dealing with time - related challenges. For example, Kurama might have some ancient knowledge about the flow of time that could help Naruto in his time - patrolling duties.
Sasuke would be a likely character to interact with Naruto as a Time Lord. Their complex relationship in the original Naruto series would add an extra layer of drama in a time - traveling scenario. Another could be Kakashi. His wisdom and experience would make for interesting conversations with Naruto, especially when Naruto has the power of a Time Lord. And of course, Jiraiya. Given his close relationship with Naruto and his own adventurous spirit, he'd be very involved in Naruto's time - traveling adventures.
It could also be a result of a powerful curse or blessing. For instance, he might be cursed by an old enemy with the ability to control time as a side - effect, but he then learns to master it. Or, it could be a blessing from a sage or some other powerful being who sees Naruto's potential and gives him this unique ability to help him save the world.
In a Naruto time - travel Minato fanfiction, Minato could be sent to the future. There, he would see how the village has changed, and might be shocked to find out about the Akatsuki and their actions. He could then work with Naruto and the others to fight against the Akatsuki using his unique skills and knowledge of the past. For example, he could teach Naruto some new jutsu that was lost over time.
Well, 'Naruto: Post - Time Skip Ascension' is also worth checking out. It focuses on Naruto's rise to power during the time skip. The author does an amazing job of exploring his newfound abilities and how they impact his place in the Hidden Leaf Village. There are also some great sub - plots involving other characters in the village that add more depth to the story.
Sasuke is also quite popular. In time - based fanfictions, he might be involved in time - traveling scenarios where he is either trying to find a way to restore his clan in a different time or he's on a mission to change the past so that certain tragedies don't occur.
A Naruto and Tsunade time travel fanfiction can be really interesting. It could involve them going back in time to change certain events in the Naruto universe. Maybe they go back to prevent a great tragedy or to save a beloved character. For example, they might travel back to the time of the Uchiha massacre and try to stop it, which would completely change the course of the story.
One great long Naruto time travel fanfiction is 'A New Path'. In this story, Naruto is sent back in time and uses his future knowledge to change many things in the Hidden Leaf. It has really interesting character development and a great plot that keeps you hooked from start to finish.
In Naruto space - time bloodline fanfiction, the bloodline abilities related to space - time are often enhanced or modified. Some fanfictions might introduce a new clan with a unique space - time bloodline. This new bloodline could have abilities like instant teleportation across long distances or the ability to create pocket dimensions. It gives the writers a chance to expand on the existing Naruto universe's concepts and create their own unique storylines.
