Prior to the outbreak, Deaver was fighting in Afghanistan along with the rest of his squad which included a lot of members that would eventually become Reapers. Upon returning from war, he struggled to find jobs or deal with trauma, but the relationship between him and his comrades remained strong. He then decided to become a mercenary.
During the beginning of the outbreak, as Operation Cobalt was put into action in an attempt to try and contain the undead threat, Pope and a group of his people managed to escape the bombings by running until they reached an abandoned church, where inside Pope was amazed to see none of them had been killed or injured, leading him to view him and his comrades as "the chosen ones". It is unknown if Deaver was present during this revelation. Regardless, he eventually joined the Reapers, and either found or crafted his own mask with a heavily scarred and gnarled expression on it, and would use this mask as a scare tactic against those who were "marked" by Pope.
Deaver and at least a dozen Reapers appear on a dark road adorned on both sides with bodies hanging from posts, with Deaver at the head of the group. Suddenly, the Reapers open fire on Maggie and her group, killing Roy and severely injuring Cole. As the Alexandrians flee into the woods, the Reapers chase after them.
Chaos breaks out in the woods as Deaver and the Reapers hunt down members of Maggie's group, killing Cole and injuring several others, including Duncan, Negan, Daryl, and Gabriel.
While Daryl is being taken in for interrogation by Carver and Powell, Deaver can be seen amongst his comrades within Meridian. Deaver is seated around the campfire eating dinner with his fellow Reapers including the newly recruited Daryl Dixon. He is shocked and disturbed when Pope horrifically kills Bossie by throwing him in the fire.
While getting some chains to secure Meridian's gate, Deaver spots Maggie hot-wiring a truck. He attempts to stop her but he fails, allowing Maggie to crash into the gate allowing walkers to enter. He later attacks and disarms her. Right before Deaver can finish Maggie off, Gabriel shoots him in the head with a rifle.
