There are fanfictions where Naruto teams up with some of the inmates in Impel Down. He might form an unlikely alliance with them to fight a common enemy that threatens both the outside world and the prison. This could lead to some really exciting battles and character development as Naruto tries to understand the inmates' motives.
Another option is to join Naruto - related forums or communities. There, fellow fans might recommend some great 'Naruto Impel Down' fanfictions that they have come across. They could also provide insights into which ones are worth reading based on their own experiences.
Female Luffy in Impel Down fanfiction might be more empathetic in a different way. While male Luffy is very open - hearted, female Luffy could show a more nurturing side towards the prisoners who have suffered. For example, she might take the time to listen to their stories more intently. Also, her physical abilities might be portrayed with a bit more grace. Instead of just brute strength like male Luffy, she could have a more fluid fighting style.
One common plot twist could be that female Luffy has unique ways of befriending the prisoners in Impel Down. Since she has a different charm compared to male Luffy, she might use her femininity to gain allies in a more unexpected way. For example, she could bond with the female prisoners in a special sisterhood - like way, leading them to help her in her escape plans. Another plot twist could be that the guards in Impel Down underestimate her because she's female, but she ends up being far more powerful and cunning than they thought, turning the tables on them in battles and strategic maneuvers.
Nami would be a great character to include as she has a deep - rooted history with Arlong. Their interactions can add a lot of drama and emotion to the story. Luffy is also a good choice as he is the main protagonist and his values of freedom and justice would contrast sharply with Arlong's tyranny.
One idea could be exploring Arlong's past before he became so cruel. Maybe there was an event that hardened his heart. Another could be a fanfic where Arlong has a change of heart and tries to make amends for his actions. For example, he could start helping the very people he once oppressed.
Arlong's back story starts with the general situation of fish - men in the One Piece world. Fish - men are generally stronger than humans underwater. However, they are not treated equally on land. Arlong witnessed the unfair treatment towards his fellow fish - men. He formed his own group and started to act in a rather extreme way. He took over Nami's village as a form of revenge against the humans. Nami, a talented navigator, was forced to be part of his crew in a sense, drawing maps for him in the hope of one day buying back her village's freedom. His actions were a result of the long - standing discrimination that fish - men had endured, but his methods were definitely not the right way to solve the problem.
Yes, there are likely non - adult fanfictions focusing on their relationship. These might explore their interactions from a more platonic or story - driven perspective. For example, a story could be about how Nami tries to understand Arlong's motives in a more complex way, without any romantic or inappropriate undertones.
