Wanted. The World's Most Dangerous Villains #4

In "Fighters Never Quit!", Master Man, wielding the Devil’s power, calls upon shadowy entities by uttering the word "Stygia"—a dangerous ability that turns the tide in his battle against the Kid's Charles Martel. When his champion Batu Khan falls, Satan himself intervenes, dragging Master Man back to Hell. Written by Bill Woolfolk and illustrated by Pete Riss with inks by the same, this 1972 DC classic features a striking cover by Nick Cardy, capturing the supernatural stakes of a clash between mortal warriors and infernal forces.
