ASTONISHING TALES (1970) #12

Terror in the Everglades! Perhaps the greatest Ka-Zar saga of all, as the jungle lord comes face-to-face with…the Man-Thing! A mysterious plane makes an unscheduled late night landing at Miami International Airport. Aboard are Ka-zar, Zabu, Barbara Morse and Dr, Paul Allen. They’re on their way to a secret laboratory in the swamp from which researcher Ted Sallis recently disappeared. They hope to find him and his secret super-soldier formula before the sinister forces of A.I.M do.
