Korak is a fictional character in Edgar Rice Burroughs's Tarzan novel series and its adaptations. Known by civilan name John "Jack" Clayton III, Korak is the son of Tarzan and Jane Porter.
History
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 his father Tarzan was kidnapped and taken to West 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 sub-Saharan 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 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
