In the manga, Mob's focus is mainly on his psychic abilities and personal growth rather than having a romantic relationship. So, no girlfriend for him.
It could be a new character, like a foreign exchange student from Beauxbatons. She has a different charm and magic style compared to Hogwarts students, which catches Harry's eye.
Well, if Naruto is attacked by a mob in fanfiction, it could lead to some interesting character development. He could use this situation to understand the common people's fear or misunderstanding of him better. Maybe he'd try to talk to them in the middle of the fight, like he did with Pain, to make them see his point of view. And depending on the nature of the mob, he could also discover new threats or allies within the group.
Sakura could potentially be Naruto's girlfriend in some fanfictions. Although in the original series she had feelings for Sasuke for a long time, in fan - created stories, the writers might explore a different path where she realizes Naruto's true worth and they end up together.
Perhaps an intelligent and patient psychologist. She could help Sheldon understand his emotions better. Given Sheldon's complex personality, she would need to be very understanding and be able to handle his idiosyncrasies. This type of girlfriend could also introduce Sheldon to the world of human emotions in a more systematic way.
Naruto could use his Rasengan to create a big enough explosion to scatter the mob and then make his escape. He might also use his speed to quickly dash through the crowd and find a hiding place.
Well, it could lead to chaos in the Hidden Leaf. His friends like Sasuke might go on a vengeful rampage. They would be filled with rage and guilt, thinking they could have prevented it. The village would also be in turmoil, as Naruto was their hero and a symbol of hope.
Well, Sasuke would be furious. Naruto was his rival and also his friend. He would seek vengeance on the mob without a second thought. Shikamaru, on the other hand, would be more calculating. He would try to figure out how such a thing could happen and what the long - term consequences for the village would be.
She could be a mysterious girl who has been watching Percy from afar and finally decides to approach him. Maybe she's a half - nymph with the ability to communicate with nature, which Percy finds fascinating.
Some fanfictions may explore Naruto getting a girlfriend in a completely alternate universe. Maybe in a modern - day setting where Naruto is just an ordinary high school student and he meets a girl who has no idea about his ninja past, which leads to a very different kind of relationship.
