Foreign correspondent Mark Todd, assigned by his newspaper to cover the Second Sino-Japanese War, is forced to take refuge in a cave during an artillery bombardment by the Japanese. There he meets the Skull Men, a strange race with burning skulls for heads. They inform him he has been chosen by the forces of destiny to be the champion of freedom, and they begin his training, which grants him abilities such as invulnerability to fire. Once his training is completed, he returns home and, motivated by the horrors of Nazism, dons a uniform with a flaming mask (in honor of the Skull Men), taking the name "the Blazing Skull". As time passes and he continues to master the Skull Men's teachings, he gains the ability to turn his flesh invisible, mimicking his teachers' appearance, and stops using the mask.
