Nothing is known about Matheson's life before or after the outbreak started, except that he was in the military. His current rank is captain but it is unknown whether he was a captain before the outbreak.
Murphy, not interested in cooperating with Zona, bites Matheson and turns him into a blend.
He is seen with Murphy, along with Dr. Merch and two other soldiers. When a group of enders attack Murphy and his newly created "blends", Captain Matheson is killed by one of them when they threw an axe to his head.
