The Nyctalope is Léo Saint-Clair (or Sainte-Claire depending on the edition), a crime fighter who can see in the dark with his eerie eyes whose irises shift colors and, as it is revealed later, sports an artificial heart. According to the internal chronology of the series, the Nyctalope was born circa 1878 (even though one of the later books updated it to 1892). His adventures roughly take place between 1898 and 1943. Saint-Clair made his first appearance in Le Mystère des XV (The Mystery Of The XV) (1911) in which the villainous Oxus tries to conquer Mars and breed a new race of supermen. This book features a fictional crossover with H. G. Wells’ Martians. Oxus had previously appeared in L’Homme qui peut vivre dans l’eau (The Man Who Could Live Underwater) (1908), which took place 25 years before and featured Leo’s father, Jean Sainte-Claire, as a supporting character. In that novel, Oxus and the mad monk Fulbert, grafted shark gills onto a hapless victim, turning him into the Hictaner, a waterbreathing man. After an interval of ten years during which La Hire wrote other novels, the Nyctalope returned in Lucifer (1921). There, he was challenged by Baron Glo von Warteck who, from his citadel in Bermuda, tried to enslave humanity with his Omega Rays. More novels followed, introducing grander villains and more incredible perils, such as Leonid Zattan, evil incarnate, Red Princess Titania, Queen of the Hashshashins, her son Belzebuth, and Gorillard the Mastodon. In Les Mystères de Lyon (The Mysteries Of Lyon) (1933), the Nyctalope fought the life-stealing Alouh T’Ho, a Chinese Empress born in 1852. In the 1943 Le Roi de la Nuit (The King of the Night), the Nyctalope flies to Rhea, a heretofore unknown planet, in an anti-gravity-powered spaceship and there, settle a war between its winged daysiders and ape-like nightsiders. The last Nyctalope story was the novella Rien qu’une nuit (Only One Night) (1944), taking place in 1941, in which the Nyctalope appears to have succumbed to the charms of collaboration with the Nazis. Two more uncompleted Nyctalope novels were finished and published by La Hire’s son-in-law in 1954 and 1955. The Nyctalope, even more than Rocambole, Arsène Lupin and Fantômas, was the first, full-fledged superhero in the history of French pulp literature.
