<Tr> <Th> Created by </Th> <Td> Pierre Boulle </Td> </Tr> <Tr> <Th> Portrayed by </Th> <Td> Maurice Evans Booth Colman Richard Blackburn (voice) </Td> </Tr> <P> Dr. Zaius is a fictional character in the Pierre Boulle novel Planet of the Apes, and the film series and television series based upon it . (In Boulle's novel, his honorific was "Mi", a term in the Ape language .) He is an orangutan and although given a minor role devoid of dialogue in the novel, he becomes the main antagonist of the story in the subsequent film adaptation . Zaius was portrayed in the first and second films of the series by Maurice Evans, in the later television series by Booth Colman, and voiced in the animated series by Richard Blackburn . Prior to that, acting legend Edward G. Robinson also gave life to the character in a short film used to pitch the story _́ s concept to executives at 20th Century Fox . </P> <P> Zaius serves a dual role in Ape society, as Minister of Science in charge of advancing ape knowledge, and also as Chief Defender of the Faith . In the latter role, he has access to ancient scrolls and other information not given to the ape masses . Zaius knows the true origins of the ape society, how humanity fell as the dominant species, and the reasons why the Forbidden Zone is so regarded, and he blames human nature for it all . Zaius seems to prefer an imperfect, ignorant ape culture that keeps humans in check, to the open, scientific, human - curious one posed by Cornelius and Zira's generation (this is due to his fear of a war of self - destruction). The idea of an intelligent human (such as Taylor) threatening the balance of things frightens him deeply . Knowing the destruction that humanity (with the aid of technology) caused in its downfall, he doesn't want even the possibility of a human resurgence . At the end of Planet of the Apes, Zaius has Cornelius's archaeological findings (human artifacts, predating the Ape society) destroyed, and Cornelius and Zira arrested on heresy charges . </P>
