The god Hermes is not in the game, but in the novel, he is responsible for informing Athena that Kratos is committing suicide. New characters include Coeus, the First Officer of Kratos' ship, and the two servants of Medusa: Jurr and a blind man. The twins encountered in the sex mini-game are revealed to be the daughters of Aphrodite named Zora and Lora. The book also explains how certain creatures of the mythology that were slain by heroes are, apparently, still alive. For example, Zeus recollects that Hercules slew the Hydra, and Athena confirms this, but informs Zeus that the new Hydra is a newborn spawn of the Titans Typhon and Echidna, and was released by Ares.
