 The story is divided into 21 chapters, with each chapter switching between the points-of-view of the supervillain Dr. Impossible and the superhero Fatale. The narrative is written in the first person, like a memoir, describing the inner monologues of the two protagonists. The dual narrative foils and "blur [s] the distinction" between the superheroes and the supervillain. The language was described as having a "sincere tone of glory" and "boyish indulgence" with "an undercurrent of sadness and a surprisingly human universality". While the story uses standard comic book story elements, like superheroes fighting supervillains, the book is written entirely in prose. The story combines a satire of superhero archetypes and comic book clichés, such as the use of many superlatives, with realist elements that portray the sometimes mundane lives and everyday challenges of its characters, like coping with cybernetic body parts that weigh far more than a natural body and that react before the brain registers what is happening. Common social situations and psychological issues, like loneliness and trying to connect with a group, are also portrayed. Reviewers identified numerous themes, such as power, greed, fame, ego, loneliness, belonging, and identity.
