In the fanfiction, Obito could start to communicate with Naruto in a unique way. Since Naruto is just a baby, Obito might use simple gestures and sounds to get his attention. He could also tell Naruto stories about the ninja world in a very simplified way, as if he was preparing Naruto for the future challenges he will face.
Obito might be initially hesitant and a bit awkward around Baby Naruto. But as time passes, he could develop a soft spot for the baby. He might play simple games with Naruto like peek - a - boo or make funny faces to make him laugh.
The story could develop with Obito training Naruto in his own way, away from the values of the Hidden Leaf. Naruto might grow up with a different set of skills and a different view of the ninja world. There could be a lot of internal conflict in Naruto as he discovers the truth about his origins and the fact that he was taken from his village. This could lead to a showdown between Naruto and the Hidden Leaf at some point, or Naruto might try to find a middle ground between Obito's teachings and his own sense of right and wrong.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
The fem Bijuus might interact with Naruto in a very nurturing way. For instance, they could use their chakra to soothe him when he is crying. They may also communicate with him on a spiritual level, sharing their stories and wisdom. Maybe the Bijuus would play games with Naruto, like simple chakra - based games to help him develop his skills early.
Sasuke might be initially hesitant but then grow protective. For example, he could sense Naruto's loneliness as a baby, just like he felt his own, and start to look out for him.
In fanfiction, Kushina might also interact with baby Naruto in a protective way when facing potential danger. Imagine a situation where some rogue ninjas are after Naruto for some reason. Kushina would put herself in front of Naruto without hesitation, using her chakra chains to fend off the attackers. And after the danger has passed, she would comfort Naruto, telling him that he is safe now and that she will always protect him.
Often, Obito is attracted to Kushina's strength and kindness. He might try to impress her with his own abilities. Their interactions could involve Obito being a bit clumsy in his attempts at first. Kushina, on the other hand, might find his eagerness endearing and start to open up to him more. They could share stories about their pasts, their dreams, which deepens their bond.
When it comes to the older generation like Kakashi, Kakashi would be very curious about Naruto's fox ears and tail. He might secretly study Naruto to see if there are any hidden abilities related to them. Naruto, on the other hand, would look up to Kakashi and try to show off his fox - related skills, like using his ears to detect enemies from afar, which Kakashi would find both amusing and potentially useful.
Sakura would probably be very shocked at first. She might be worried about Naruto's well - being and also a bit fearful of the combined entity. Kakashi, on the other hand, would be more understanding. Given his connection to both Naruto and Obito, he would try to communicate with the merged form to figure out what happened. Sasuke would be initially suspicious, thinking it could be some new threat. But after seeing that Naruto's essence is still there, he might be more accepting and see it as a new power to use against their common enemies.
Their relationship could begin with a misunderstanding. Maybe Female Obito has a mission that initially seems to conflict with Naruto's goals. However, as they communicate more, they realize they are actually on the same side. This leads to them working together closely. As time passes, Naruto's positive attitude rubs off on Female Obito, and she becomes more open and friendly. They could eventually become like family to each other, always having each other's backs.
The story could start with Naruto finding Obito in a desolate place. Naruto would be curious and approach him. Then, they would exchange words, and Naruto would offer his help to Obito. As they interact more, they might face some small - scale battles together against rogue ninjas or other threats. This would build trust between them.
