Sasuke could be a time - traveler in a One Piece fanfiction. He gets sent from his own ninja - filled world to the world of One Piece. He has to adapt quickly to the new environment. His goal could be to find a way back home, but in the process, he gets involved with the various power struggles in the One Piece world. He might end up using his Sharingan to help the Straw Hats in battles against the Marines or other pirates.
One plotline could be that Sasuke is from a hidden ninja - like island in the One Piece world. He is sent out on a mission to find a Devil Fruit that has the power to unlock the secrets of his clan's past. Along the way, he crosses paths with the Straw Hat crew and initially clashes with them due to his cold and brooding nature.
In some fanfictions, Sasuke travels to different hidden villages to learn about their unique cultures and ninja techniques. This allows him to grow as a person and a ninja without any inappropriate 'lemon' elements. Also, there are stories where he mentors the next generation of ninja, passing on his knowledge and experiences in a positive way.
Sasuke's character could potentially bring a new level of intensity to the One Piece world. His Sharingan abilities, like seeing through illusions and predicting movements, might make him a formidable opponent. He could be a lone wolf type of character in the Straw Hat crew, initially aloof but gradually warming up to the others, much like Zoro in some ways.

For example, a new powerful enemy from the Nine Realms emerges and Loki's insights are crucial in the fight.
One storyline could be that Sasuke is a fallen Jedi and Sakura is sent to find him. She has to face many challenges in the galaxy to reach him and then convince him to return to the light side. Another could be that they are both on opposite sides of a galactic war. Sasuke is with the evil empire - like the Sith - and Sakura is with the rebels. They have to fight each other but also deal with their feelings.
One possible plotline could be Sasuke's reintegration into the village. Sakura could play a big part in helping him adjust. They might face some opposition from villagers who still don't trust Sasuke completely. Another plotline could be their journey to find missing - nin or remnants of the enemy forces. During this, their relationship could develop as they rely on each other for support.
