“White Apes: These are terrible monsters with a cunning almost equal to human. Many seem to have a rough tribal organization, and those that do always use stone (or some other form of) clubs. . . They infest the abandoned cities of Barsoom, and they are also found in many other places.” The 6-limbed white apes of Barsoom were said to be a favorite monster of Gary Gygax, eventually reappearing as D&D’s girallon. (Greg Bell, Warriors of Mars by Gygax and Blume, TSR, 1974)
