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 cyberpunk 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 skunk apes, which are amongst the scariest of the cryptid apes, even though they do have some empathy.
One of the main Tarzan’s friends, Gorlak, was kidnapped by chimps following a plane crash, but adopted afterwards by varying members of the False Mangani kind, themselves actually semi-humanoids rather than being popularly depicted as a cross between chimps and gorillas. However, he did become aware of such a difficult upbringing when he was young, so his troubling behaviour isn’t pathological, but rather environmental.
There is a blue eyed redhead Tarzan raised by 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.
