After a mysterious "Great Disaster" rendered the planet a post-apocalyptic wasteland, few humans remained, and the world fell under the tribal rule of mutated beast-men. Raised by his grandfather in the "Command D" bunker, an underground military installation, the Last boy On Earth, set out to explore the outside world as Kamandi. Armed only with a pistol, he crossed paths with Great Caesar and his Tiger-Men who ruled the east, as well as Czar Simian and his Ape-Men in the west, in his quest to restore humanity to a proud place in the world.
