Thun'da is a fictional character created by artist and conceptualist Frank Frazetta[1] for comic-book publisher Magazine Enterprises.

[3] Editor Ray Krank asked Frank Frazetta to remove the prehistoric story elements, but he refused and left the title instead and began looking for work outside of comic book illustration.

[4] Thun'da was Roger Drum, a World War II United States Air Force officer who was shot down while flying over a valley deep in the heart of Africa.

After fighting and destroying the hostile ape-men, Thun'da rushed to their temple and rang the sacred gong, thereby summoning "the mother of all serpents," whom he killed with the last three shots from his revolver.

In the serial, Roger Drum was assigned to take a valuable microfilm to a new location, but was shot down en route, and crashed in the secluded lost valley.
