One interesting Whitebeard Pirates fanfiction could be about a new crew member joining them. This new member has a unique power that the crew has never seen before and they have to figure out how to incorporate it into their battles and daily life on the ship.
Whitebeard himself is often a very popular character in fanfiction. His powerful presence and fatherly role in the crew make him a central figure. Writers can explore his leadership, his past battles, and his relationships with the other crew members.
Some of the pirates might be excited to meet Sabo, especially those who knew Ace well. They could see Sabo as a link to their fallen comrade. Others might be more skeptical, fearing that Sabo could bring trouble from the Revolutionaries. Overall, it would be a mix of reactions depending on the individual members of the Whitebeard Pirates.
Well, in many fanfictions, a common storyline is the training Ace received from the Whitebeard pirates. It shows his growth within the crew. Also, there are stories about their feasts and celebrations on the ship, which give a sense of the crew's camaraderie. Some fanfictions even create alternate universes where the Whitebeard pirates and Ace face different challenges not in the original story.
One idea could be that the male OC is a former slave who was freed by Whitebeard. He has a deep sense of loyalty towards Whitebeard and is always ready to fight for his newfound family. His unique ability could be related to some form of water - based combat, which is rare in the One Piece world.
Well, if the Whitebeard Pirates join Luffy in fanfiction, it would be a game - changer. Luffy already has a diverse crew, but adding the Whitebeard Pirates would mean a whole new level of firepower. Think about it, the Whitebeard Pirates have their own strong fighters like Marco. With them on Luffy's side, they could raid more dangerous territories, maybe even find the One Piece faster. And there would be a lot of interesting character interactions. Luffy's carefree nature might clash and also blend well with the more experienced members of the Whitebeard Pirates.
In the fanfiction, when the Whitebeard Pirates meet Sabo, there could be a show of strength on both sides at first. However, Sabo's connection to Luffy might make the Whitebeard Pirates more friendly towards him. Ace was part of the Whitebeard Pirates, and since Sabo was like a brother to Ace, they could end up having a big celebration in honor of Ace's memory, with Sabo learning more about his time with the pirates.
First, think about his backstory. For example, he could be an orphan who was taken in by the Whitebeard Pirates. This would give him a strong motivation to protect his new family. Then, consider his skills. Maybe he has a superhuman strength that he uses in battles. Also, his personality is important. He could be a joker in the crew, always making everyone laugh during tough times.
The story could develop in many ways. One way is that they could start by exploring new islands together. The Whitebeard Pirates' experience would help Luffy's crew avoid some of the usual pitfalls. And in battles, they could use combined strategies. For instance, Luffy's Gear techniques combined with Whitebeard's fruit powers. Another aspect could be that the two crews' different cultures and values could merge, creating a new pirate culture within the story. This could attract more characters to join them, expanding their influence across the One Piece world.
I think Ace is the top choice. His internal struggle between his loyalty to Whitebeard and his past with Gol D. Roger is a goldmine for fanfiction writers. But we can't forget Jozu either. His strength and his unwavering loyalty to the crew are aspects that can be developed in interesting ways. And Vista, with his swordsmanship, can be a really cool character to write about in relation to the crew's battles.
