Sakura is often quite popular. In college fanfiction, she might be a brilliant medical student, still having her feelings for Sasuke while also becoming good friends with Naruto. Her strong - willed nature and intelligence can add a lot to the story.
In many such fanfics, Naruto's character often becomes more vulnerable yet also stronger in a different sense. His pregnancy makes him rely on Sasuke more, but at the same time, he is determined to still be a great ninja. Sasuke, on the other hand, becomes more nurturing. He steps up to protect Naruto and the unborn child, showing a side of him that was not as evident before.
Naruto would likely become more stable. With Anko as his adoptive mother, he'd have a stronger support system. He might be less impulsive as he has someone to guide him. Sasuke, on the other hand, could start to open up more. His cold exterior might soften as he experiences Anko's love and care. He could also learn to trust others more easily.
Kakashi Hatake is a popular choice. He has a long history with both Naruto and Sasuke, having trained them. He could be included to offer guidance or add some comedic moments. For example, he could give them some tough training exercises that help them bond more. Another popular character is Sakura Haruno. She has her own complex relationship with both Naruto and Sasuke. Her presence can add some drama, like if she has to choose between helping Naruto or Sasuke in a difficult situation.
I think Kakashi could be really popular. Since he has a connection to both Sasuke and Naruto, his role in a time - travel story could be very interesting. He might be able to help them adjust to the past or use their knowledge to his advantage. Another popular character could be Itachi. His actions in the past are so crucial to the story, and in a time - travel scenario, he could interact with Sasuke in a whole new way.
Kakashi would be a great addition. His wisdom and combat skills could add depth to the story. He could act as a mentor figure, guiding Naruto and Sasuke through the strange situations they find themselves in due to the fox - related elements.
Sakura is a very popular character to include. She has a long - standing relationship with both Naruto and Sasuke. Her medical ninjutsu skills can be very useful in various plot situations. Kakashi is also popular. His experience and unique jutsu can add depth to the story. Another popular character is Shikamaru. His intelligence can be a great asset in devising strategies against enemies.
I like Naruto in these fanfics because he always stays true to his beliefs. He is constantly trying to bring Sasuke back to the village and is willing to fight for their friendship.
Gaara is a character that can be well - written in this context. He has his own experiences with darkness and redemption. He might understand Naruto's possible fall into evil in a different way compared to others. He could offer his unique perspective to Sasuke on how to deal with Naruto. Also, Tsunade could be important. As the Hokage, she has to make difficult decisions regarding the threat that an evil Naruto poses to the village and how to support Sasuke in his efforts to stop Naruto without causing too much destruction.
They are often re - imagined as more independent. Without the full influence of Konoha, Naruto might not be as eager to seek approval from the village. Sasuke, too, could be seen as less consumed by his revenge against the village. Instead, they are more focused on each other and their own relationship.
