Well, in a lot of fanfictions about Luffy vs Katakuri, Luffy's growth is depicted quite vividly. His growth can be seen in his improved observation Haki. He starts to anticipate Katakuri's attacks more accurately, which is a huge step forward. He also becomes more creative with his attacks. Instead of just using his standard punches and kicks, he combines different moves and even creates new ones on the fly. This shows that he's evolving as a fighter and not just relying on his basic skills. Another aspect is his mental growth. He faces a very tough opponent in Katakuri, but he doesn't give up. His resolve gets even stronger, which is an important part of his overall growth in these fanfictions.
The "Negative Fruit" in One Piece was one of the superpowers that Luffy encountered for the first time in the story. The scene where Luffy and his gang fought against the "Negative Fruit" appeared in episode 598,"Luffy and Luffy!" Adventures in Two Worlds.
One of the most exciting moments could be when Luffy first uses his new gear or technique that surprises Katakuri. It shows Luffy's growth and adaptability in the fight. Another exciting part might be when Katakuri reveals a new form or power that Luffy has to quickly figure out how to counter. This back - and - forth of power display and strategic thinking keeps the 'fanfiction' action - packed.
He could meet his future self. It would be an interesting encounter as he could learn from his future experiences and wisdom. Or he might meet people who have studied his past adventures and see himself through their eyes.
He might start by observing. Aang is a curious person, so he'd likely watch how people live, how they interact with technology. He may also try to find other benders to learn about any new developments in bending. And he'd probably use his kind heart to make friends easily in this new future environment.
In some fanfiction, Aang's tattoos might be depicted as glowing with a special power when he reaches a new level of understanding or connection to the Avatar state.
Aang could be friends with Neville. Neville is often underestimated but has a lot of courage, just like Aang. They could bond over their shared experiences of being different. Also, Luna Lovegood might be interested in Aang's unique abilities and his different world view, so she could be a potential friend too.
In non - lemon fanfiction, Aang is often portrayed as his kind - hearted self, trying to bring peace and balance. He might be shown using his airbending skills in creative ways to solve problems or face challenges. Azula, on the other hand, is usually depicted as a complex character. Her intelligence and powerful firebending are emphasized, and she may be in a journey of self - discovery, either trying to redeem herself or continue her pursuit of power in a more nuanced way.
Aang's age in the comics varies depending on the specific storyline, but generally, he is depicted as a bit older than in the original animated series.
