An attempt to capitalize on the popularity of The Planet of the Apes franchise (1968, 1970, 1971, 1972), it is set an a post-Apocalyptic world where sentient animals rule (everything from apes to rats), and humans are extinct.
Though described as "a boy" and "a tyke," Kamadi is drawn as an extremely muscular teenage with long blond hippie-hair, naked except for tight cut-off jeans.
He is captured a lot, muscles taught and struggling. Or he fights with high kicks that display his bulging pecs and 8-pack abs almost as well.
For the next 30 issues, Ben and Kamandi fight together, rescue each other, search the ruined cities for each other. Kamandi occasionally meets girls, momentary dalliances that mean nothing. And there is no question for Ben: he has eyes only for the blond muscle god.
