Klaus Voorhees was an ex-convict working with the humanitarian medical researcher Professor Ezekiel Shecktor in India on a universal anti-toxin for snake venom. Jealous of Shecktor's success, Voorhees plotted to kill him and make the murder look like an accident. Hence, Voorhees induced one of the cobras kept in the laboratory to bite both Shecktor and himself. Voorhees planned to use the universal anti-toxin to save himself from death. Unknown to Voorhees, the cobra had been irradiated. The combination of the radioactive venom in his bloodstream and the experimental anti-toxin which he used created a mutagenic catalyst which gave Voorhees certain cobra-like powers.
