Anthony's prolific career is marked by several long-running series that explore diverse themes within fantasy and science fiction. The Xanth series, his most extensive, is a humorous fantasy world with a unique magical system. The Incarnations of Immortality series delves into philosophical concepts, personifying abstract forces like Death, Time, and Fate. The Cluster series and its spin-off, the Tarot series, explore interconnected narratives with a science fiction bent. Other significant series include the Battle Circle, Of Man and Manta, Apprentice Adept, Bio of a Space Tyrant, and Geodyssey, each presenting distinct worlds and narrative arcs. These series often feature intricate plots, unique characters, and explorations of societal structures and cosmic principles.

Beyond his solo endeavors, Piers Anthony frequently collaborated with other authors, notably Robert E. Margroff, on projects such as 'The Adventures of Kelvin of Rud' series and individual novels like 'The Ring' and 'The E.S.P. Worm.' He also worked with Roberto Fuentes on the Jason Striker series and with authors like Mercedes Lackey, Philip José Farmer, and J.R. Rain. His standalone works include 'Macroscope,' which earned a Hugo Award nomination, and 'Total Recall,' a novelization of the film. Anthony's non-fiction output includes autobiographical accounts like 'Bio of an Ogre' and 'How Precious Was That While,' offering insights into his life and creative process.

While not explicitly categorized as esoteric, many of Anthony's works touch upon philosophical and metaphysical themes that resonate with readers interested in deeper meanings. The Incarnations of Immortality series, for instance, personifies fundamental aspects of existence, inviting contemplation on mortality, free will, and the nature of reality. The Tarot series, originally conceived as part of the Cluster continuity, suggests underlying cosmic orders or destinies. Even within his more overtly fantastical settings like Xanth, there are often underlying explorations of balance, choice, and the consequences of actions, presented through allegorical narratives and character journeys.
