One possible plot could be a grand adventure where they team up to take on a powerful enemy that threatens the safety of their hometown. They could use their combined skills and the strong bond they share to overcome challenges.
One great 'ace luffy sabo fanfic' is 'The Brothers' Bond'. It beautifully portrays their relationship and the adventures they might have had together. Another is 'Sabo's Return', which focuses on Sabo coming back into Luffy and Ace's lives in a very emotional way.
Their reunion would likely cause a stir in the pirate world. Other pirates would see them as a very powerful group. It could also inspire many young pirates to strive for stronger bonds with their comrades, just like Luffy, Ace and Sabo.
Another interesting one is 'Sabo's Return: With Ace'. In this story, Sabo returns much earlier than in the original story. It details how he and Ace reunite and the impact it has on the Straw Hat crew and the overall One Piece world. The story is full of action and heart - warming moments between the two.
I really like the fanfictions that involve Ace, Whitebeard and Sabo. They are such interesting characters. In many of these fanfictions, the relationship between them is explored in great depth. For example, how Sabo copes with having Ace as his 'brother' again after thinking he was dead. And Whitebeard's role as a father figure to them adds another layer of complexity and warmth to the stories.
One of the main attractions of this type of fanfiction is the chance to delve deeper into the characters' psyches. Ace and Sabo have complex backstories, and when we add the 'Back Scream' concept, it's like opening a Pandora's box of emotions. For instance, we might see how Ace's memories of his mother influence his actions, and how Sabo's memories of his noble family's rejection shape his view of the world. These memories, with the added intensity of the 'Back Scream', can create a very engaging story.
Fanfiction writers often play with the idea of unfulfilled dreams or destinies. Ace and Sabo had so much more they could have done. So, in some fanfics, their memories are so strong that they exist as a sort of spiritual force. And this force is then able to influence events in a way that leads to their physical resurrection. For example, their memories might guide Luffy to a place where he can find the means to bring them back.
In an 'Ace Sabo Memories: Back Scream' fanfiction, the story could center around a mysterious force that makes them relive their most painful memories. This force could be related to an ancient devil fruit power or some sort of dark magic. Ace might remember the time he was rejected by his father, and Sabo could be forced to recall the moment he thought he lost his brothers. The 'Back Scream' then becomes their internal struggle against these overwhelming memories.
One popular Sabo x Luffy fanfiction is 'The Brothers' Bond'. It beautifully explores their relationship with lots of emotional moments. Another good one could be 'Sabo and Luffy: New Adventures' which takes them on a whole new set of exciting quests. There's also 'Sabo, Luffy: Reunion' that focuses on their reunion and how it impacts their future.
In fanfiction, when Sabo and Luffy meet again, they might have an emotional reunion. They could share stories of their adventures since they last saw each other. Sabo might show off his new skills or powers, and Luffy would be excited to see his brother again. They could also plan new adventures together, vowing to face any challenges as a team.
