His anger could slow down the progress of the crew. For example, if they were on a mission to an island and Luffy's anger at Nami stops them from working together efficiently. The crew might get distracted from their main goals as they deal with the internal conflict. In fanfiction, this can be used to explore different aspects of each character's personality and how they handle such difficult situations within the crew.
If Luffy kisses Nami, it could cause a stir among the crew. Sanji might be extremely jealous as he has his own feelings for Nami. Zoro, on the other hand, would probably make sarcastic remarks about it. But overall, it could also bring the crew closer as they see Luffy and Nami in a new light and start to think more about relationships within the group.
If a marine joins Luffy's crew in a fanfic, it could be quite interesting. At first, there might be a lot of distrust among the crew members. After all, they've been fighting against marines for a long time. But if the marine has a strong sense of justice that aligns with Luffy's own view of right and wrong, they could gradually be accepted. For example, the marine might bring in some new combat techniques or knowledge about the navy's operations that could be useful to the Straw Hats.
Imagine Luffy ate a devil fruit that gave him the power to control minds. This would be a very different power compared to his current Gum - Gum abilities. His crew would have to trust him completely not to abuse this power. There could be ethical discussions within the crew. Also, in terms of leadership, Luffy might have an easier time getting others to follow his plans, but it could also create some tension if the crew felt he was relying too much on his mind - control powers instead of his natural leadership qualities.
His anger could lead to a complete breakdown of their relationship in some fanfictions. Naruto might feel so betrayed or frustrated that he decides he doesn't want to be around Sakura anymore. But in other fanfictions, it could be a turning point for their relationship. Naruto's anger might make Sakura see him in a new light, as someone who has his own boundaries and feelings, and she might start to respect him more, which could improve their relationship.
It could strain their relationship. Goku might start to avoid ChiChi if he's mad at her. For instance, he could spend more time training alone in the mountains or with his friends rather than at home with ChiChi.
Ginny's anger could make Harry realize his mistakes and try to make amends. This might strengthen their relationship in the long run as they work through their issues. However, in the short term, there could be a lot of tension and arguments. Ginny might also start to question whether Harry is really the right person for her, and Harry could start to feel insecure about their relationship.
Their relationship could become strained. Ginny might start to question her love for Harry. In some fanfics, she could even consider leaving him. This would put a lot of pressure on Harry to fix things and make amends.
It can create a lot of tension within the team. The story could then focus on how they try to resolve this tension. For example, they might have to have a series of heart - to - heart conversations to understand where Ruby is coming from and vice versa. This can lead to character development for all of them.
It could put them in a lot of danger. The World Government would target them. But it could also strengthen their bond as they face the challenges together.
Fem Luffy would probably bring a lot of energy. She might be more empathetic in some ways compared to the original Luffy, which could help in resolving internal crew conflicts. For example, if two crewmates have a disagreement, she could use her charm and understanding to smooth things over.
