Maximilien Robespierre is a blond poet who appears in the anime Le Chevalier D'Eon. He maintains personal connections with Durand and Lia de Beaumont and is first seen leaving France alongside the Russian spy Vorontsov. Formerly a French secret agent, Robespierre turned against the King shortly before Lia's death, a decision that defines his later actions. In the story, he frequently urges Durand to join his Revolutionary Order, reflecting his commitment to the revolutionary cause. He also haunts D'Eon, perceiving him as the vessel of Lia's spirit. Robespierre's personality is generally calm and devoid of strong emotion, presenting a composed and detached demeanor even as he pursues radical aims. His motivations stem from a deep ideological opposition to the monarchy, which led him to abandon his earlier role as a royal agent and embrace revolutionary ideals. His key relationships include his past ties to Durand and Lia, his brief alliance with Vorontsov, and his antagonistic fixation on D'Eon. Developmentally, his turn against the king marks a clear break from his past, though the series does not explore his later transformation in depth. Instead, his role is that of a catalyst and a shadowy figure who embodies the coming revolutionary storm. His notable abilities appear to be those of a skilled agent and poet; he is also capable of a haunting presence that unsettles D'Eon.
