Korak is the Honorable Jack Clayton, son of English Lord John Clayton, Viscount Greystoke, also known as Tarzan, lord of the jungle. He is the hero of a 1915/6 magazine serial and 1917 novel by American writer Edgar Rice Burroughs and a 1920 silent movie serial, as well as a character in several other Tarzan stories from 1914 to 1924. He experienced a revival in 1964 as the star of his own comic book series and as a major character in various Tarzan comic books, pages, and strips from 1966 to 1978.
In 1966, ABC released the TV series Batman, featuring the frequently imperiled youthful sidekick Robin the Boy Wonder. As a fan of seeing cute, young sidekicks in trouble, I watched every episode.
Russ Manning took over the Sunday Tarzan pages in 1968. His Korak tended to have a tall, lean, swimmer's build. While the son of Tarzan continued to have somewhat autonomous adventures, the slender, handsome youth seemed to be getting into trouble more frequently and more easily. Moreover, in the Sunday Tarzan pages, Korak tended to suffer from more frequent comparisons to his legendary father.
