One way to write a cheering up scenario in a Naruto fanfiction is to have his friends come together. For example, Sasuke could return after a long time and they have a friendly spar. During the spar, they exchange words of mutual respect and understanding, which could cheer Naruto up as it shows the bond between them is still strong.
One possible scenario could be that Sakura is feeling down because she failed a difficult medical ninjutsu exam. Naruto, being the good friend he is, takes her out for her favorite ramen and tells her stories of his own numerous failures and how he never gave up. This cheers her up as she realizes that failure is just a stepping stone to success.
Naruto's optimistic personality is a big factor. His ability to always see the bright side of things can rub off on Sakura. For example, if Sakura is worried about a mission, Naruto will be all like 'Don't worry, Sakura -chan! We've faced tougher things and we always come out on top!'. His positive outlook makes Sakura believe that things will be okay.
Perhaps they are in a dangerous situation where they are being chased by powerful enemies. Sasuke decides to make a risky move to protect Naruto but misjudges his own strength. His attack aimed at the enemies accidentally grazes Naruto. This would create a lot of tension between them, with Sasuke blaming himself and Naruto trying to ease his guilt.
Yes, there could be such fanfictions. Fanfiction allows for a wide range of creative interpretations. Some writers might deviate from the original characters' traits and create a story where Hinata cheats on Naruto. But this is not in line with the general perception of their relationship in the original series.
In a fanfiction, Naruto could become the Mizukage through various means. Maybe after some great diplomatic efforts between Konoha and the Hidden Mist Village. He could prove himself worthy by helping the Mist Village solve some internal problems like dealing with rogue ninja groups that the Mist has been struggling with. His skills in combat and leadership would also play a big role. He could train the Mist ninja in new jutsu and battle strategies, thus earning their respect and ultimately being named the Mizukage.
Well, in such a fanfic, Naruto might use his positive attitude. For example, he could share some of his ninja training stories that are full of funny mishaps. The 'lemon' could be a lemonade stand that he sets up to cheer the person. Maybe he tells the person how he once made a huge mess trying to make lemonade for his friends but still had a great time.
One possible scenario could be after Naruto loses a difficult battle. Hinata might find him sitting alone, looking dejected. She could sit beside him and start by saying how she saw his amazing efforts during the fight. Then she might share some of her own insecurities and how Naruto's determination has always inspired her. This would remind Naruto of his own importance and boost his spirits.
There are also fanfics where Naruto cheers up a young genin who is feeling down because they failed a mission. Naruto shares his own experiences of failure and how he learned from them. He encourages the young ninja to keep trying and not give up, showing that setbacks are just part of the journey to becoming a great ninja.
Naruto's reaction could be complex. He might be sad and disappointed, but he also has a lot of love in his heart. He could try to forgive his teammates, believing that there must be some misunderstanding. However, if they continue to oppose him, his reaction would turn more towards self - preservation and growth. He would focus on his own development, both as a ninja and as a person. He would use this betrayal as a motivation to become stronger, all while still hoping that one day he can reconcile with Team 7.
A fanfiction might depict fem Naruto's life with her parents alive as a story full of family moments. They could celebrate birthdays and festivals together. Minato and Kushina would be able to guide fem Naruto in her social life too. She wouldn't be the lonely outcast she was in the original story. Instead, she would be a popular kunoichi with her parents' reputation. Her parents could also help her develop her own fighting style that combines their techniques, making her a very strong and unique ninja in the Hidden Leaf Village.
