It could make Naruto more responsible. Since he has to take care of the baby fox, he'll have to think about another being's needs. For example, he can't just go on long missions without making arrangements for the fox.
Well, one possible plot could be that the baby fox has some special powers. Maybe it can communicate with Naruto telepathically and helps him in his ninja missions. For example, it could sense danger before Naruto does and warn him.
Sakura might be a bit cautious at first. She'd worry about the fox being a danger or a distraction. But after seeing how Naruto cares for it, she'd warm up and might even help Naruto take care of it, like making sure it has proper food. Sasuke would probably be indifferent at first, but if the fox showed some useful skills in battle, he'd start to respect it. Shikamaru would just sigh and say it's too troublesome, but still offer some strategic advice on how to keep the fox hidden from enemies if needed.
Maybe Naruto finds the baby fox while he's exploring an unknown area. The fox is injured, and Naruto uses his medical ninjutsu to heal it. The fox then becomes attached to Naruto. As the story progresses, the fox helps Naruto in battles by using its speed and small size to its advantage, like sneaking up on enemies and stealing their weapons or intel.
Well, one interesting plot could be Naruto having to rely on his friends in a whole new way as a baby fox. Since he can't communicate as he used to, his friends have to figure out his needs through his actions. Another plot might be that Naruto discovers new abilities or powers in his baby fox form that he didn't know he had before.
One great fanfiction is 'The Fox - Eyed Naruto' on FanFiction.net. It really delves into how Naruto's fox - eyed appearance changes the way people perceive him in the village. The author does an amazing job of integrating this new physical trait into the existing Naruto universe storyline.
One possible scenario in this fanfic could be that Naruto discovers the baby fox while on one of his adventures in the forest. The baby fox might be injured or lost, and Naruto's kind heart leads him to take care of it. Their snuggles could represent the bond of trust and friendship that forms between them. It could also be a symbol of Naruto's connection to the natural world in the Naruto universe.
Well, he might have shown superhuman strength, like being able to break things that normal babies couldn't. Maybe he could also sense danger in an uncanny way, like a sixth sense.
One common theme is power. Often, the fanfictions explore how Naruto's connection with the fox gives him new and enhanced powers. He might use these powers to fight stronger enemies or to protect the village. For example, in many stories, Naruto can access different forms related to the fox that boost his strength and speed.
