One popular Usopp fanfic might be those that focus on his growth as an inventor. For example, stories where he creates new and amazing gadgets for the Straw Hat crew. Another could be fanfics that explore his relationship with other crew members in more depth, like his friendship with Luffy and how they support each other during tough times.
I recommend One Piece: The Great God Usopp to you. This book is a story about Usopp. It tells the story of how he obtained the League of Legends system through an accidental transmigration and became invincible. If you want to read a One Piece Doujinshi novel with a deceptive cloth as the main character, this book is perfect for you. I hope you will like my recommendation.
In the past, Usopp's abilities like his slingshot skills might be seen as more primitive compared to the advanced weaponry in his own time. But his creativity could give him an edge. For example, in a time when there were less advanced long - range weapons, his slingshot could be a very unique and effective tool. In the future, if he travels there, his abilities might seem obsolete at first. However, he could adapt by using his knowledge of old - fashioned combat and combine it with the new technology he finds.
One common theme is teamwork. Since they are both part of the Straw Hat crew, many fanfictions explore how they work together. For example, in some stories, Usopp uses his inventions to assist Nami in her navigation tasks. Another theme is friendship evolving into something more. Writers often show how their bond deepens over time, starting from a simple crewmate relationship.
One common theme is friendship development. Since they have different personalities, seeing how they become closer and understand each other better is often explored. For example, Sanji's chivalry and Usopp's cowardice at times can create interesting dynamics as they learn to accept and support each other.
There could be a sense of relief. Kaya, who has always worried about Usopp during his adventures, would feel relieved to have him back safe, and this relief could turn into a passionate kiss. Usopp, on the other hand, might feel a sense of accomplishment, like he has finally come home to someone who truly cares for him, and that could also be expressed in the kiss.
Friendship turned to more is a very common theme. Since they start as crewmates with a normal friendship in the original, fanfictions often explore how that can develop into a romantic or deeper emotional bond.
