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.
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.
Zoro would be deeply affected. He has sworn to follow Luffy and his death would be a huge blow. He might feel like he failed in his duty to protect the captain. He would likely become more withdrawn at first, but then focus on getting stronger to avenge Luffy if there was someone to blame for his death.
Nami would be inconsolable at first. Luffy has always been there to protect her, and his sudden death would leave a huge void in her life. She would probably cry for days. As time passed, she would remember all the things Luffy taught her about courage and believing in oneself. Nami would start to take on some of Luffy's leadership qualities in a way. She would be more outspoken about her plans for the crew and more determined to see their dreams through. She would also keep Luffy's memory alive by telling stories of his adventures and his selfless acts to new people they meet on their journey.
Nami might be shocked at first. She'd probably look at Luffy with wide eyes, not believing what she just heard. After all, Luffy is not the most romantic or traditional suitor.
The crewmates would have a range of reactions. For one, they trust Luffy's ability to handle himself, but they'd also be eager to reunite with him. Luffy's impulsive nature often leads him into adventures, and this time it's in a whole new world. The more level - headed ones like Nami and Robin would be thinking of strategies to either bring him back or join him. The fighters like Zoro and Sanji would be prepared to defend Luffy against any threats in this new and unknown Naruto world. And the rest of the crew would contribute in their own unique ways, whether it's through humor like Brook or scientific exploration like Franky.
They might be shocked. Luffy's Gear 5 is such a powerful and strange form. In the fanfiction, characters could be amazed at his new abilities, like his cartoon - like movements and seemingly limitless power.
Nami would probably be devastated. She has been with Luffy through so much, and his death would be a huge blow. She might become more withdrawn and serious, as Luffy was often the one to bring out her lighter side.
Nami would probably be shocked at first. She might worry about how this would affect Luffy's journey to become Pirate King. But then she would likely start thinking about practical things like how to take care of the baby on the ship. Sanji would be over the moon, seeing it as an opportunity to cook for a new little life. He might also be a bit jealous that it's Luffy and not him having a baby with Hancock.
