Well, one possible future for them in Marine fanfiction could be that they form a special unit. Ace with his fire power, Luffy with his rubber abilities and Sabo with his skills would be a formidable team. They could be sent on special missions to deal with the toughest pirates. This way, they are still following their dreams of adventure while being part of the Marines.
A marine who has a special ability or talent that the crew lacks. Maybe a marine who is really good at deciphering ancient texts or has a unique form of martial arts. They would be attracted to Luffy's crew because of their freedom - loving spirit. And once they join, they could use their skills to help the crew in their adventures, whether it's finding a hidden treasure or fighting against a powerful enemy.
In some fanfictions, female Luffy might be portrayed as having the same adventurous spirit as the original male Luffy. She could be fearless in the face of danger and always eager to explore the Grand Line. However, being a female in the Marines' world might bring some unique challenges. For example, she may have to deal with more discrimination in a male - dominated organization like the Marines. But she would still hold onto her dreams and values, just like the Luffy we know.
The idea of Ace, Luffy, and Sabo in the Marines is quite interesting. They could use their bonds to make the Marines a more family - like organization. Their unique abilities would also give them an edge. For instance, Luffy's stretching powers could be used in creative ways during rescue missions or combat.
I think it has the potential to be very engaging. A marine joining Luffy's crew would bring in a clash of ideologies and force both the marine and the crew to adapt and grow. It could lead to some unexpected plot twists and character developments.
In 'luffy vs kaido fanfiction', Luffy's growth and new abilities are often explored. He might develop new forms of his Gear powers to face Kaido. Kaido, being extremely powerful, forces Luffy to push his limits. Fanfictions may also focus on the intense battle scenes, with detailed descriptions of their attacks and counter - attacks.
Yes. The conflicts between Sanji and Luffy in the manga often stem from complex circumstances and character developments that drive the narrative forward.
