Ka-Zar's first solo story was published in Marvel Super-Heroes #19 (1969), and the character had features in the black-and-white magazine Savage Tales and the color title Astonishing Tales. Kevin Plunder refers to himself as the "Lord of the Savage Land", a phrase others have adopted, but this is not a formal title. Originally written as a primitive and belligerent savage who spoke in broken English, Ka-Zar later became more articulate and civilized, although he retained a certain degree of distrust toward civilization and was generally wary of outside visitors to the Savage Land. The character was based on his pulp magazine namesake only to the extent that he used the same name and rough "jungle lord" concept, and Lee later admitted that he had never even read any of the original Ka-Zar stories. Created by Stan Lee and Jack Kirby in The X-Men #10 (March 1965), he lives in the dinosaur-populated Savage Land, which was hidden beneath Antarctica by extraterrestrials.

The second Ka-Zar started as a character similar to the first Ka-Zar, but also reminiscent of both Tarzan and of writer-artist Joe Kubert's 1950s caveman character, Tor. Cover to the X-Men #10 the first appearance of Ka-Zar and his sabretooth tiger, Zabu art by Jack Kirby.
