In the fanfiction, their relationships can be delved into through flashbacks. Remembering their time together before the events at Marinford, like their childhood days. As they return to Marinford in the future, they might have different reactions based on their relationships. Luffy might be more impulsive due to his emotional connection with the place where Ace died. Sabo, being more level - headed, tries to keep Luffy in check while also sharing his own feelings. They can have deep conversations about their future plans and how their relationships will support or change those plans.
One possible plot could be that in the future, Luffy, still driven by his dream of becoming the Pirate King, decides to return to Marinford. Ace and Sabo, who are also with him, have their own reasons for going back. Maybe they want to set things right after the chaos that occurred there before. Luffy could be aiming to make a statement that the new generation of pirates is different and stronger. They might face old enemies or find some sort of hidden treasure or knowledge that was left behind during the previous battles.
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.
Perhaps in this fanfiction, Ace, Luffy and Sabo will make Marineford a place where pirates and marines can live in harmony. They could set up some rules that both sides can abide by.
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.
In this fanfiction, Ace, Luffy and Sabo could have a future in Marineford that is full of hope. Maybe they work together to change the perception of pirates in that place. Ace could use his fire power to protect the weak, Luffy with his unwavering will continues to inspire others, and Sabo with his intelligence devises plans to make Marineford a more inclusive place for both pirates and marines.
In fanfiction, their relationships are sometimes explored through shared battles. For instance, they might all fight together against a common enemy, like a powerful navy fleet. During these battles, the trust between Ace, Sabo, Luffy, and the members of Whitebeard's crew is emphasized. The relationships are also shown through quieter moments, like when they are all on the ship sharing stories and dreams, which helps to strengthen the bond between them all.
Well, in fanfiction, Luffy's bond with Ace and Sabo is unbreakable. They grew up together and share a lot of memories. When it comes to the Marines, they represent the 'order' that Luffy and his brothers are sort of defying as pirates. Some fanfictions might show a young Marine recruit who has a change of heart after seeing the strong bond between Luffy, Ace, and Sabo. He starts to question whether the Marines are always in the right. Usually, though, the Marines are there to create conflict for the trio.
Ace's relationship with Whitebeard is already established, but it could grow to be more of a father - son type relationship. Luffy would be in awe of Whitebeard and his crew, and his relationships with everyone would be based on his infectious enthusiasm. Sabo, being the more rational one, would study Whitebeard's leadership style and learn from it. As for the relationship between the three brothers, they would support each other during battles and share their dreams and experiences with the rest of the crew, which would in turn strengthen their bonds with the Whitebeard pirates.
Their relationships would likely develop in a very positive way. Ace already has a connection with Whitebeard. When Sabo and Luffy join, they would be welcomed into the family - like atmosphere of Whitebeard's crew. Luffy, with his infectious enthusiasm, would quickly make friends with the other crew members. Sabo, being more serious - minded, would earn respect for his skills. Ace would act as a sort of bridge between them and the rest of the crew, and over time, they would all become closer, sharing their dreams and fighting side by side.
One great 'Ace Sabo Luffy Fanfiction' is 'The Brothers' Bond'. It beautifully explores their relationship, showing how they support each other through various challenges. Another one is 'Sabo's Return'. It focuses on Sabo coming back into Luffy and Ace's lives and how they all readjust. There's also 'Ace and Luffy's Adventure', which takes the three on a fictional journey filled with action and heartwarming moments.
