Well, obviously Naruto himself. Their interaction would be really fascinating as Naruto could see his future son and Bolt could see his father as a young man. Also, Sasuke would be a great character to interact with Bolt. Sasuke's skills and his complex personality would create some really intense scenes when interacting with Bolt.
Maybe Bolt travels back to a time when the Akatsuki was at its peak. He could use his knowledge of future events and his own skills to try and take on the Akatsuki, creating a whole new set of battles and alliances. For example, he might form an alliance with Itachi before his death and together they could try to take down the other Akatsuki members.
There's also a fanfiction called 'Time - Twisted Bolt Uzumaki'. This one is a bit more complex. Bolt not only travels through time but also has to deal with different versions of himself from alternate timelines.

In Bolt Uzumaki time travel fanfiction, the exploration of different eras in the Naruto universe is a major element. We see Bolt experiencing the old ways of ninja life, different battle styles, and unique cultures. His own growth as a character during these time - traveling experiences is also key. He might learn new jutsus, gain wisdom from the past, and use that to face challenges in his own time. And of course, the mystery and adventure that come with time travel, like solving the puzzles of why he traveled and how to get back, are essential elements.
In a more complex plot, there could be an evil force that wants to change the timeline in a way that would be disastrous for Bolt and Himawari's world. So, they have to time - travel through different eras to gather artifacts or powers that can stop this evil force. Along the way, they form new friendships, face their own fears, and learn more about each other and their place in the world.

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.
Another type of fanfiction could explore their relationship in a more personal way. Maybe Bolt is sent to the Naruto universe for some reason, and Naruto takes him under his wing as a mentor. They could have heart - to - heart conversations about their dreams and responsibilities, which would be really cool to read.
