When Naruto takes off his weights in fanfiction, it could completely revolutionize his training. He might find that he can now train with stronger opponents, like the elite jounin or even the Hokage. This would expose him to different fighting styles and strategies, which in turn would help him grow as a ninja. Also, his physical training could now include more acrobatic and aerial maneuvers that were previously difficult with the weights on. His chakra control might also be affected, as the change in his body's movement could require different levels of chakra distribution. This could lead to him exploring new ways of using his chakra in combat and non - combat situations.
He could suddenly become extremely fast and startle his friends. Maybe he zooms around the village, leaving a trail of dust, and his friends are left in awe of his newfound speed.
It might be that Naruto has found a new power or ability that makes the prosthetic unnecessary. For example, he could have developed a new form of chakra control that allows him to function without it. Also, perhaps he is about to engage in a fight where the prosthetic would be a hindrance rather than a help, like if he needs to be more agile and the prosthetic is weighing him down.
Rock Lee has a sad story of constantly facing challenges due to his inability to use ninjutsu at first. He was often looked down upon by his peers. But he didn't give up. He trained extremely hard, pushing his body to the limits with his taijutsu. For example, his weights that he always carried around were a symbol of his self - imposed hardship. All he wanted was to prove himself as a great ninja in his own way.
I don't really know if the 'rock lee ghost story' is popular. It could be popular within a niche community of fans who are really into Rock Lee and also interested in ghost stories. But if it's not widely known outside of that small group, then it's not very popular in general.
In the fanfiction, Robin might reveal a secret identity or a hidden face with a unique scar or mark. It could also lead to a moment of great vulnerability, where his friends see a side of him they never expected.
It could be a story where Percy takes his shirt off during a training session. Maybe he's getting ready for a really intense sparring match and removing his shirt is part of his pre - fight ritual to show his determination and focus.
Rock Lee's sad story makes him extremely determined. Since he was not good at ninjutsu initially, he had to work hard to prove himself. This led to his strong - willed character. He never gives up no matter how difficult the situation is.
It could be Might Guy. He already has a strong bond with Rock Lee, almost like a father - son relationship. So it would make sense for him to officially adopt Rock Lee. He would continue to train Lee in his own unique and intense way, and they would have many more adventures together.
His friends might be concerned at first. They could think he's in some kind of trouble or that he's given up. But once they understand his reasons, it could strengthen their bond as they support his decision.
