Not many people know that Tarzan of the Apes has two dozen sequels written partially or not by ERB, and fewer people know that the (authorised and canonical) Tarzan books are a franchise of their own.
Instead, a heroic bloodshed reboot of Disney’s variants will predominantly borrow and twist the scenery and character designs of various different shows, comics and films rather than of the novels themselves, because most of their major characters are on the loopy and complex process of (prohibitively) getting trademarked and being slapped with registers.
While the main Tarzan does have various human acquaintances, his true human friends are few and far between. He is raised primarily by the giant Ogre Mangani, which are amongst the scariest of the apemen, even though they do have some empathy.
The False Mangani kind are themselves actually semi-humanoids rather than being popularly depicted as a cross between chimps and gorillas. Some of his stablest friends are Carla and fellow gorillas. He is a strong heavyweight who became their transitionary leader (following Matt’s untimely murder by poachers), until Flynt (the latter’s nephew in law) takes over permanently. He is a very stubborn fella, who pounds his chest for different purposes and smashes things when upset.
