who will be the 10th member of straw hat pirates

One great rival could be a character with a powerful Devil Fruit ability. For example, a character who has a Logia - type Devil Fruit that allows them to turn into a natural element like lightning. This would make them very difficult to defeat in combat as they could dodge attacks easily. They could also use their element - based powers to attack the Straw Hat Pirates in unexpected ways, such as sending bolts of lightning towards their ship.

They might have an epic celebration. The Straw Hats would be excited to see Shanks, especially Luffy. Luffy would probably challenge Shanks to a friendly duel or just be overjoyed to show him how far he's come. Shanks would be proud of Luffy and his crew, and they could all share stories of their adventures over a big feast.

First, understand the Straw Hat Pirates' personalities well. For example, Luffy's carefree and determined nature. Then, create an OC (Original Character) that can interact meaningfully with them. Maybe the OC has a special skill or a unique backstory that ties into the pirates' adventures. Think about how the OC can join their crew or be an ally in their journey.

One popular trope is the 'lost relative' trope. For example, the OC could be a long - lost relative of one of the Straw Hat Pirates. Another is the 'powerful newcomer' trope, where the OC has some extraordinary power that helps the crew in a difficult situation. There's also the 'love interest' trope, although this can be a bit overdone. The OC might fall in love with one of the pirates or vice versa.

Luffy and Zoro's bond would still be strong. Maybe in a reincarnated life, they meet as rivals at first in a martial arts tournament but soon realize they share the same goals and become partners again. Nami and Usopp could be siblings in their new lives, with Nami being the protective older sister and Usopp using his creativity in a new family dynamic.

Luffy would be furious. He'd immediately set out to rescue Sanji without a second thought. He'd probably charge straight at Doflamingo's stronghold without a proper plan at first, just driven by his anger and determination to get his crewmate back.

Well, it depends on the setting of the fanfiction. If it's a steampunk world, Luffy could be a daredevil pilot with his stretchy body helping him in acrobatic flying. Zoro might be a mechanical swordsman, with his blades enhanced by steam - powered technology. Nami could be a navigator on an airship, using her knowledge of winds and weather in a whole new dimension.

Luffy would likely run up to Shanks with a big grin and start chatting non - stop about his adventures. Shanks would listen with a smile. The rest of the Straw Hats would be a bit more reserved at first, but then they'd join in. Sanji might offer to cook for everyone, which Shanks would surely appreciate.

😋I recommend Reborn Pirates Musou to you. The main character, Mu Yang, was reborn as a soul after his death and came to the world of One Piece. He joined the Grass Hat Pirates and began a series of adventures. I hope you will like this novel where the protagonist joins the straw hat pirates.😘

First, you need to establish the backstory of the OC rival. Why do they see the Straw Hats as their enemy? For example, if the OC was once wronged by a member of the Straw Hats accidentally. Then, think about the OC's abilities and how they can challenge the Straw Hats. Maybe the OC has a power that can nullify Luffy's rubber abilities for a short time. As the story progresses, the OC can gradually gain respect for the Straw Hats through different encounters, like when they team up against a common enemy. This could lead to a change in the OC's attitude towards them.
