Jean-Louis Duboi is a French line infantryman of the 1er Régiment d'Infanterie in the Napoleonic Era. He is a tragic, anxious, and somewhat disoriented person who is still deeply disturbed and startled by the recent Fléau breakout, the zombie infection. Despite this, he has a strong sense of patriotism, is resilient, a religious catholic, and will stop at nothing to save people from the zombie hordes. Despite simply being a line infantryman, he is exceptionally clever and an able leader.
