Book excerpt: A brave heroine whose quest involves living her true gender. A genderqueer knight who battles the transphobic court to save their prince. Often fearing discovery, the trans hero embarks on adventure, aided by an accepting mentor and other allies, and challenged by transphobic villains and sometimes uncomprehending family members. Ultimately, the trans hero triumphs, finding love, selfhood, and affirmation. This book adapts Joseph Campbell's classic pattern of comparative mythology and applies it to trans and non-binary heroes in modern popular media who are traversing multiple worlds. Analyzed are works for the screen such as Steven Universe, The Matrix, Sense8, and Sandman; print materials such as DC and Marvel comics; and television, fantasy books, and graphic novels from trans and non-binary creators worldwide.
