Coelho
Atlas's head of medicine
Coelho leads Atlas's school of medicine and wants enough time to continue his research against disease and death. His journals reveal that he has repeatedly taken descendants' bodies to preserve his own life, treating the deaths and resistance of their families as obstacles to his work.
He courts Yara for the strength and intelligence he hopes a future child will inherit; she accepts in order to investigate Atlas. After his body is defeated, he possesses his young son, Coelho Jr. He blames Yara and insists that his research justifies his choice.
