One of the most shocking revelations could be Naruto's early days as an outcast. Boruto, who has always known his father as a respected figure, would be surprised to learn that Naruto was once shunned by the village. Another could be the danger Naruto faced as a young ninja, like fighting against the Akatsuki. It's so different from Boruto's relatively more sheltered life in the beginning.
If Boruto finds out about Naruto's past through fanfiction, it could initially create a sense of awe. Boruto might start to understand the hardships his father faced more deeply. He could become more empathetic towards Naruto. For example, learning about Naruto's lonely childhood might make Boruto appreciate his father's presence in his own life more. This discovery could also inspire Boruto to be more like his father in terms of determination and never giving up.
Well, Boruto could be very inspired. Naruto's past is full of struggles, from not having parents around to being constantly underestimated. When Boruto discovers this in the fanfiction, he might realize that his own problems are not as big as he thought. He could be motivated to work harder and not take for granted the things he has, seeing how much Naruto had to fight for everything.
Boruto might be in awe. He has always known his father as the Hokage, a powerful and respected figure. Seeing Naruto's past full of struggles, loneliness, and determination would make him realize how far his father has come. It could also make Boruto more empathetic towards Naruto and perhaps inspire him to be more like his father in some ways.
One key event could be Naruto's time at the Ninja Academy. He was often alone and had no one to practice with, yet he still persevered. Boruto would see how Naruto's determination started early. Another event might be when Naruto fought against Haku and Zabuza. It was a dangerous battle that showed Naruto's courage. And of course, Naruto's training with Jiraiya would be important. Jiraiya taught Naruto so much, and Boruto would understand how this mentorship shaped Naruto into the person he became.
If everyone found out about Harry's past in fanfiction, there would be a mix of reactions. Some people would probably pity him more, knowing the hardships he had faced before. But others, especially those who were jealous of his fame, might spread rumors or distort the facts. This could also have an impact on how the wizarding community views Dumbledore, as he had been a big part of Harry's past and his decisions related to it.
Another aspect could be Naruto's training with Jiraiya. Boruto might read in the fanfiction about how Naruto traveled with Jiraiya, trained hard, and grew not just in strength but also in character. Jiraiya taught Naruto many important lessons about life and being a shinobi. This could give Boruto a newfound respect for his father's journey to becoming the Hokage.
One possible consequence is that Harry might face a lot of unwanted attention. People in the fan fiction world could start treating him differently, perhaps with too much pity or excessive curiosity. His privacy would be invaded, and he might feel pressured to conform to the expectations that others now have of him based on what they've learned from the fan fiction.
Well, if Anakin discovers Obi - Wan's past in the fanfic, he may be shocked. Depending on what that past entails. If it involves some sort of hidden training or a past alliance that Anakin didn't know about, he could become suspicious. He might question Obi - Wan's motives for not telling him earlier. On the other hand, it could also inspire Anakin, seeing Obi - Wan's journey and how he overcame things in his past.
