Korak (character)  Korak, a fictional character, is the ape name of John "Jack" Clayton III, Earl of Greystoke, the son of Tarzan and Jane Porter. Jack first appeared in the original "Tarzan" novels by Edgar Rice Burroughs. He was introduced as an infant in the non-Tarzan novel "The Eternal Lover" (later retitled "The Eternal Savage"), in which the Ape Man and his family played supporting roles. His next appearance (still as an infant) was in "The Beasts of Tarzan", the third Tarzan novel, in which he was kidnapped and taken to Africa. The story of his youth and growth to manhood was told in the fourth novel, "The Son of Tarzan", in which he returned to Africa and lived in the jungle, taking for the first time the name Korak ("Killer" in the language of the Great Apes). Most references to him were as "Korak the Killer". Half of the book relates to Meriem, the Arab girl he rescues from a beating. The two of them run wild in the forest for years before being separated. After many adventures they are re-united and eventually marry. Korak was later used as a supporting character in the eighth through the tenth entries in the series, "Tarzan the Terrible", "Tarzan and the Golden Lion", and "Tarzan and the Ant Men". The last of those three also briefly mentions Korak and Meriem's young son "Jackie". The Bunduki series by J. T. Edson - and authorized by the Burroughs estate - includes Korak and Meriem's granddaughter Dawn as one of two main characters. Besides the Burroughs novels, Korak also appeared in the 1920 movie serial "The Son of Tarzan", the Tarzan comic strip, in which he was a major character for many years; and the "Tarzan", "Korak, Son of Tarzan", and "Tarzan Family" comic books. In the Johnny Weissmuller Tarzan films, Korak was replaced by an adopted son called Boy (played by Johnny Sheffield). Tarzan and Jane never married in these films (they do in the books), and the substitution was made to avoid censorship. In the Dell comic books of the 1950s, which combine material from the books and the films, Tarzan's son was also called Boy. When the Tarzan comics returned to a more faithful portrayal of Burroughs' characters in the early 1960s, Boy disappeared and Tarzan's son was called Korak, who was later featured in his own comic book.
