Prior to the outbreak, Powell was fighting in Afghanistan along with the rest of his squad which included a lot of members that would eventually become the 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 Powell was present during this revelation. Regardless, he eventually joined the Reapers, and either found or crafted his own mask with a wide-mouthed, jagged-toothed expression on it, and would use this mask as a scare tactic against those who were "marked" by Pope.
Powell and at least a dozen Reapers appear on a dark road adorned on both sides with bodies hanging from posts. 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 Powell and the Reapers hunt down members of Maggie’s group. Powell kills a wounded Cole by slitting his throat open. The mayhem continues as either he or his comrades wind up injuring several others, including Duncan, Negan, Daryl, and Gabriel.
As Daryl later on engages in a fight with Brandon Carver, Powell is among the Reapers to arrive as reinforcements, forcing Daryl to run off again. The next day, after Leah Shaw reunites with Dog and confronts Daryl, Powell, Brandon, and several other Reapers surround him and take him captive. Brandon and Powell forcibly Daryl back to Meridian for interrogation, and are both later seen retrieving a similarly captive Frost from his cell for similar inquisition.
Powell is present at Daryl's initiation, waiting outside with all the other Reapers for the inductee to pass the test. As Pope declares Daryl "forged by fire", Powell and the rest of the Reapers welcome Daryl with a latin mantra.
Powell attends the fireside dinner talking with the others, where Daryl eats his first meal as a Reaper, and subsequently watches in silence as Pope burns Bossie alive, accusing him of turning his back on his brothers and letting Michael get killed.
After Daryl successfully tortures Frost for information as another test by Pope, Powell is among the several Reapers who are sent out to check the house their prisoner had said Maggie and the others were hiding in. Paired up in a squad lead by Leah working alongside Daryl, Carver, Washington and Fisher, Powell is sent with the last two to breach the back entrance of the home, after which he and his squad-mates check every room in the house before declaring it "clear". Leah sends Washington, Powell, and Fisher to check the rest of the town, while she, Daryl, and Carver stay behind to give the building a once over.
Powell returns back to Meridian at the end of the episode during nightfall, where Pope reveals he further tortured and subsequently killed a now undead Frost, claiming he "got everything he needed out of him."
Powell is seen exiting the food shed, as a smoking Daryl watches with Dog. In an attempt to build a deceitful connection to the person in charge of guarding Meridian's rations, Daryl asks Powell if he needs any help. Powell declines, putting a lock on the door. Daryl then offers Powell a cigarette, who accepts and thanks him for the offer. As Daryl lights it for him, the two hear the other Reapers talking in the distance, and Powell surmises that Washington and Ancheta have returned from patrol.
Powell is present when Pope and the rest of the Reapers are observing the herd. He is later seen guarding the sentry post, where Daryl joins him, claiming Pope sent him, and offers him another cigarette. Powell accepts, and jokes about having to "quit them again." Daryl then drops the matches on "accident", and stabs Powell through the throat when he reaches down to pick them up. His body is then immediately disposed of over the railing.
