Thun'da is a fictional character created by the artist Frank Frazetta for Magazine Enterprises, a comics publisher. The story of Thun'da was first released as a comic series in 1952, as Thun'da #1. 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 crashing, he freed himself from his aircraft only to be captured by hostile ape-men. He managed to escape, and wandered through the valley, pushing himself to exercise daily and becoming a paragon of physical perfection. It was while he was wandering that he was spotted by Pha, the queen of the people who lived in the valley. 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. He won the respect of Pha's people, and they worshipped him as if he were a god. Later, after an earthquake ravaged the lost valley, Thun'da was able to get Pha to safety along with their pet sabretoothed tiger, but her people were killed and the lost valley was sealed from them forever.
The character, played by Buster Crabbe, was the main character in the 1952 Columbia Pictures serial King of the Congo.
