Review Detail of Lunarian_King in In One Piece, with a Mythical Zoan fruit...

no creativity, characters are pretty much dead, too short, almost no conversations = AI content (Chat GPT). use your own effort to make a story, those AI cannot help you make even half decent story, why go the easy and unrewarding way? wreck your brain for ideas, write them down and try stitch them to make a proper plot and start writing from there. decide how your character look and he's personality, try using your own effort, you may fail once, twice,... but you will learn and improve, eventually you will be able to write something that can satisfy YOU, don't try to satisfy others, write what YOU like.
