137 Abstract This article uses Pedro Valencia’s play Con Z de zombie (2013) to theorize the Mexican drug war through the lens of the zombie apocalypse. As the play’s title shows, Valencia asserts a connection between zombies and drug traffckers; indeed, the entire play allegorically critiques the ideologies of the drug war and advocates for sincere dialogue between narcos, civilians, and the state. The playwright employs theatrical techniques that challenge biopolitical constructs that have kept different segments of society apart from each other since the war began. Building on the work of Roberto Esposito, who argues that modern states aim to “immunize” individuals against the excesses of “dangerous communities,” I assert that the three characters of this play represent different segments of society that have come into confict with each other as a result of the drug war. Valencia asserts that this divisions undermines any attempts at peace when his human characters befriend a zombie who has regained consciousness. These characters soon learn that they can only successfully navigate the zombie apocalypse if they work together. At an allegorical level, then, the play asserts that the state must facilitate a communion between (repentant) narcos, civilians, and the military if it wishes to mediate drug violence in the country.
