Diego Castillo is Antón's 13-year-old son and heir. His father is teaching him to rule through fear, but Diego is quiet, unsure and far less cruel than Antón wants him to be.
Diego is being raised to take over from his father. Antón's lessons in leadership lean on fear, such as handing him a live grenade to make a point. Diego shows sympathy for the people his father hurts and openly says nobody liked José.
He appears in the opening on the refugee boat, then in cutscenes with Antón between operations. His story runs alongside the main campaign until the final assault on Esperanza.
Tired of his father, Diego tries to flee with his nanny on the refugee boat. Antón finds him and orders everyone else on board killed. At Coronado Prison he cannot shoot Julio Vélez, but later he shoots José in the back on his father's order. He also slips a journalist Viviro for her sick father.
Diego kills General Sánchez to save Dani. In the presidential tower he begs Dani to spare his dying father. Dani promises to protect him, but Antón shoots Diego before killing himself.
