Nothing is known about Othón's life before the apocalypse.
Othón is first seen on patrol through Tijuana with his fellow bodyguards, looking for someone. Later, he is seen in the cafeteria at the Gonzalez Dam when Dante Esquivel arrives for lunch. Later, Othón accompanies J.C., Daniel, and another bodyguard on a scouting mission to look for the unauthorized water source and finds Efrain's hideout. Back at the dam, Othón is in the interrogation room after Efrain is eventually captured. When it is decided that he, Lola, and others are to be executed, he is at the dam's edge with Dante and stands guard over the captives. However, he is shot and killed by Daniel after he turns his gun on Dante and his men.
After J.C. is shot in the head, Othón runs over to Dante to protect him but is shot in the chest by Daniel.
