White Apes were natives of the planet Barsoom, and they were among the most feared creatures on the entire planet. Often taking shelter in the ruins of anceint cities, John Carter, Warlord of Mars was forced to fight these creatures on several occassions. Resembling huge African gorillas, they had four arms and were hairless except for their heads. They were massive creatures, standing around 15 feet tall when erect, possessing tremendous strength and a ferocity "unmatched by anything on Earth." They were substantially stronger than John Carter or any other Barsoomians, and their intelligence was roughly equal to that of an angry gorilla.
