Born in South Africa in 1918, three-year-old David Rand accompanied his British parents John and Constance on a flight to Cairo to visit his grandfather.

With the support of Zar, David became the jungle's leading warrior within a few years challenging different animals like Bardak the Ape and N'Jaga the Leopard.

With the help of the local animals, Ka-Zar established himself as the guardian of the jungle which involved meting out harsh retribution to any intruder seeking to exploit his resources-but he frequently aided more benign explorers, such as when he protected Prof. Rice and his daughter Mara from the criminal pilot "Red" Skelton, rescued Rita Grey from the Wabi tribe, and helped two Scotland Yard detectives capture murderer London Jack.

Surviving attacks by entrenched Nazi forces, Ka-Zar and Zar confronted Sarput who was ultimately slain by their ally Trajah.

After preventing his inheritance's theft by John Rand's law partner Alec Wright, Ka-Zar donated the wealth to war relief in England.

Following one such encounter, Ka-Zar was restored to health by an aged witch doctor, who gave him a brew used centuries before to grant his tribe superhuman strength.

Last time anyone heard from Ka-Zar, he protected his region's wildlife when Africa was threatened by monstrous tidal waves from Atlantean warfare.
