In 1981 John Byrne began his six-year run writing and illustrating Fantastic Four, sparking a "second golden age " for the title but also attempting to "turn the clock back [...] get back and see fresh what it was that made the book great at its inception." Doctor Doom made his first appearance under Byrne's tenure with issue #236. Whereas Kirby had intimated that Doom's disfigurement was more a figment of Victor's vain personality, Byrne decided that Doom's face was truly ravaged: only Doom's own robot slaves are allowed to see the monarch without his helmet. Byrne emphasized other aspects of Doom's personality; despite his ruthless nature, Victor von Doom is a man of honor. Returning to Latveria after being temporarily deposed, Doctor Doom abandons a scheme to wrest mystical secrets from Doctor Strange in order to oversee his land's reconstruction. Despite a tempestuous temper, Doom occasionally shows warmth and empathy to others; he tries to free his mother from Mephisto and treats Kristoff Vernard like his own son. Byrne gave further detail regarding Doom's scarring: Byrne introduced the idea that the accident at Empire State University only left Victor with a small scar that was exaggerated into a more disfiguring accident by Doom's own arrogance—by donning his newly forged face mask before it had fully cooled, he caused massive irreparable damage.
