To write an engaging Big Mom Pirates self - insert fanfic, first, really study the characters in the Big Mom Pirates. Know their personalities, goals, and relationships. For example, Big Mom herself is a complex character with a huge appetite and a strict family structure. Then, think about how your self - inserted character would fit into this world. Maybe your character has a special ability that can either help or challenge the pirates. Also, create interesting plotlines. It could be about a treasure hunt with the pirates or getting involved in their internal power struggles.
One common trope is the underdog story. Your self - inserted character is often new and not very powerful at first compared to the established Big Mom Pirates. They then have to prove themselves. Another trope is the discovery of a hidden power or ability within the self - inserted character. It could be unlocked during a dangerous encounter with the pirates. And there's also the 'fish - out - of - water' trope, as the character is usually from a different background and has to adjust to the strange and often brutal world of the Big Mom Pirates.
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.
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.
As of now, in the manga, the identity of Luffy's mom remains unknown. There have been many theories and speculations among fans, but no official confirmation.
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 recommend "Reborn in One Piece World." The main character of this novel became brothers with Luffy, Ace, and Sabot, and they fought hard for their beliefs in the world of One Piece. I hope you like my recommendation. Muah ~
