Religion is a prominent part of society, although the dominant religions have evolved. A merging of the major religious groups of the 20th century has resulted in the First Amalgamated Church, while Voodoo is now mainstream. New religions include Oprahism, Robotology, and the banned religion of "Star Trek" fandom. Religious figures include Father Changstein-El-Gamal, the Robot Devil, Reverend Lionel Preacherbot, and passing references to the Space Pope, who appears to be a large crocodile-like creature. Several major holidays have robots associated with them, including the murderous Robot Santa and Kwanzaa-bot. While very few episodes focus exclusively on religion within the "Futurama" universe, they do cover a wide variety of subjects including predestination, prayer, the nature of salvation, and religious conversion.
