Korak Son of Tarzan #33 (1970)

After rescuing a friendly tribal chief from poisoning, Korak pursues the evil witch doctor, who has kidnapped the chiefs son; Hypnotized by a mirror shining sunlight into his eyes, Korak imagines a variety of strange animals attacking him, until he feints from the disorientation; Catching the witch doctor from behind, Korak underestimates the villains wiliness, earning a chop to the side of the neck, which floors him; While shielding the chiefs son from a volcanic explosion, the jungle boy is knocked out again by a hurtling rock to the head, just before a pack of hyenas arrives.
