Addison Grace "Addy" Carver is a former member of the Blue Sky camp in New York and is Mack's girlfriend prior to his death. She is the survivor group's communication specialist and uses her talents with radio equipment to contact Citizen Z. Broken by unresolved trauma, she is slowly being worn down by the apocalypse. At one point, she chooses to leave the group and join the Sisters of Mercy camp, but after the camp is destroyed, she reunites with Mack, who refused to leave her behind, and returns to the Westward-bound survivor group. Her weapon of choice against zombies is a customized metal bat with spikes; in season 3, her bat is upgraded by Sun Mei and her team to emit an electric charge similar to a taser. Between seasons 3 and 4, she loses her right eye. She disappears early in season 4.
