Well, Naruto in fanfiction often shows his emotions verbally. He's not one to hold his tongue. So, he might passionately declare his love for Hinata in a really sappy and over - the - top way that makes everyone around him roll their eyes but also feel the warmth of his emotions. Also, when he's sad, he could be shown as isolating himself from the group, which is a clear sign of his inner turmoil.
Well, first of all, Jiraiya gives Naruto a sense of family. Naruto has always been an orphan, and Jiraiya steps in as a father figure. He shows concern for Naruto's growth, not just as a ninja but as a person. He encourages Naruto to be true to himself. In terms of ninja training, he doesn't just teach Naruto techniques but also the strategy and wisdom behind them. And when Naruto makes mistakes, Jiraiya is there to correct him in a patient and understanding way, which is a very important quality of a good godfather.
He might show his scars to Sasuke. Given their complex relationship, it could be a powerful moment between them, a way to show Sasuke that Naruto has also faced great pain in their separation and the events that followed.
She might have cooked his favorite meals. In fanfiction, a stepmother showing love could be as simple as preparing the food Naruto likes. For example, making ramen just the way he prefers it.
Yamato might show his concern by constantly checking on Naruto's condition. He could be seen sitting by Naruto's bedside, feeling his forehead for fever regularly.
Naruto would probably show a very inclusive leadership style. He always values his friends and their opinions, so he'd likely involve everyone in the decision - making process in the village.
Sakura might show her care for Naruto in fanfiction by always being there to heal his wounds. Since she is a skilled medic - ninja, she could be depicted as dropping everything to tend to Naruto whenever he gets injured during a mission or a fight.
In many fanfictions, Naruto shows his protectiveness of Hinata by always being by her side during dangerous situations. For example, when there are enemy attacks, he quickly positions himself in front of Hinata to shield her from harm.
They can also show heroism by protecting the village. Kakashi, with his vast experience, could come up with strategies to prevent further damage to the village. He might use his earth - style jutsu to create barriers against landslides that the earthquake has triggered.
