Mi Zaïus was a leading orangutan scientist on the ape-dominated planet of Soror, the title 'Mi' denoting a rank of honour. The head of the Research Institute, he was informed by Zira that she had discovered a human who was capable of thought, and even of speech. Zaïus, who did not believe the fact that man could have a soul or a spirit, dismissed her claims as nonsense, but was discredited when Ulysse Mérou made a convincing address to the ape masses.

NotesEdit

• The character 'Doctor Zaius' from the movie adaptation, Planet of the Apes, was based on Mi Zaïus.
