In this respect, L'Homme truqué bears witness to this post-war period when an unprecedented need for reconstructive surgery appeared in France and which pushed the latter to solve complex cases and to progress. A superhuman born in the trenches: scientific wonder at work The First World War was such a deadly conflict that it caused a real trauma among the population. Indeed, it is in this context that the terms " superhuman " and " superheroes " are used more and more frequently in Europe as well as in the United States to qualify the heroes who distinguish themselves in this extraordinary conflict. Promoter of the scientific-marvel genre, which aims to give a new point of view on the potentialities of science, Maurice Renard makes an analogy, in the plot of L'Homme truqué, between this new look and the superhuman vision of the character. Following his surgery, Jean Lebris gains an extraordinary vision, which allows him to discern things like people's nervous systems and heat sources, especially in the dark or through walls. Through the genius doctor Prosope, Maurice Renard proposes a phantasmagorical explanation to justify the sixth sense acquired by Jean Lebris: the electroscopes make it possible to capture electricity, in the same way that ears grafted in place of the eyes would have made it possible to see sounds. Endowed with his extraordinary vision, Jean Lebris describes an environment bathed in an electric field, whose slightest anomaly, the smallest variation reflects a particular hue. This gift, extremely powerful even for his eyelids, obliges him to wear special glasses that block his vision. The electric implant graft, far from being an ocular repair, is really conceived as a transhumanist augmentation. Indeed, his augmented vision even allows him to observe strange creatures made of electricity, living unbeknownst to the common man, like the Sarvants, the invisible spiders that Maurice Renard portrays in his 1911 novel Le Péril bleu. In L'Homme truqué, this invisible life form exists in the immediate environment of human beings in the form of orbs. The common mortal, not possessing sensory organs sensitive enough to perceive them, is unaware of the very existence of these electric beings. However, if Jean Lebris is indeed a superhuman made by the war, he is not a superhero. Moreover, he gradually becomes aware of his role as a guinea pig, so much so that, refusing his new status of superhuman, he
