Well, perhaps the OC is a time - traveler who goes back in time to meet Gold Roger. They form an unlikely alliance and together they face a powerful enemy that was a threat not only to Roger but also to the future of the One Piece world. The OC could also be a self - taught swordsman who wants to learn from the great pirates of the past, like Gold Roger, and through their alliance, they learn valuable lessons about life and piracy.
One idea could be that the OC is a long - lost relative of Gold Roger. They embark on a journey to discover the secrets he left behind. Maybe they find a hidden map in an old family heirloom that leads to a powerful treasure. Another plot could be the OC being a former crewmate of Gold Roger who was thought to be dead. They resurface to protect something Roger entrusted to them from the wrong hands.
An OC who joined the Gold Roger crew later in their journey. This OC has a different view on piracy compared to the others. The story could be about how this OC's ideas start to influence the crew, causing some internal conflicts at first but eventually leading to a new and more united way of operating. This could show the diverse personalities within the crew and how they grow together.
First, give the OC a backstory. For example, if they grew up on an island that was often raided by pirates, it would make sense for them to be interested in allying with someone like Gold Roger. Also, give them a unique skill or trait, like being an excellent navigator. Second, consider their personality. They should have qualities that would make them compatible with Roger's crew. Maybe they are brave and loyal. Finally, think about their goals. If their goal is to find a certain treasure or to bring peace to the seas, it could be a reason for them to ally with Roger.
One idea could be that the main character uses the power of darkness to fight against an oppressive regime. They can move unseen in the shadows, gather intelligence, and strike when least expected.
One idea could be that Austin and Ally accidentally end up babysitting a super energetic and mischievous baby. They struggle at first but then learn a lot about responsibility and grow closer in the process.
One idea could be that Austin and Ally are in a songwriting competition where they have to write a love song. As they work together, their real feelings start to surface. Another could be a time - travel plot where they go back to the start of their friendship and relive some key moments, realizing how much they've changed. A third idea is that they get trapped in a music store overnight and end up having a jam session that reveals their hidden emotions.
One idea could be a time - travel plot where Austin and Ally are sent back to the 1960s and have to adapt their music styles to fit the era. Another could be a story where they face a rival music duo who tries to steal their spotlight by spreading false rumors about them. Maybe a story where Ally loses her songwriting ability and Austin has to help her find it again through a series of adventures and self - discovery.
A plot could revolve around Roger and Anita hosting a big party for all the dalmatians' friends. They have to plan everything from the food to the entertainment. Roger might be in charge of the music and Anita the decorations. Along the way, they encounter some problems like not having enough food or a sudden rainstorm threatening to ruin the party, but they manage to solve them together.
One idea could be a time - travel plot where Naruto somehow gets sent to the One Piece world during Gol D. Roger's era. He could learn from Roger and use his ninja skills in the pirate world.
The entire crew of Gold Roger could potentially be allies in a way. They are a tight - knit group. The OC could bond with different members over shared interests. For instance, the cook might share food with the OC and in return, the OC could help him find rare ingredients during their travels. This sense of community within the crew can be a strong support for the OC.
One idea could be that Ally and Jack meet before the events of the movie in a small local music venue. They both perform separately that night and are immediately drawn to each other's unique styles. Another could be a post - movie fanfiction where Ally struggles to continue her music career without Jack, but finds strength in his memory and the lessons he taught her. A third idea is that they have a secret songwriting project together that they keep hidden from the public eye and the drama that unfolds as they try to keep it a secret.
