To write 'Star Wars Reacts Fanfiction', start by choosing the characters you want to feature. If you pick Han Solo, for example, think about how his cynical and roguish nature would influence his reactions. You need to set the scene properly, whether it's on the Millennium Falcon or in a seedy cantina. Consider the emotions that the event they're reacting to would evoke. Fear, excitement, or anger. And when it comes to dialogue, make it snappy and in - character. You can also draw inspiration from other fanfictions, but always add your own creative touch to make it your own story. Keep in mind the overall tone of Star Wars, which is a mix of adventure, hope, and a touch of the mystical.
