When AvatarKorra, ChiefLin Beifong, and Tenzin arrived at the Sato estate to investigate a claim that Hiroshi Sato operated a hidden Equalist factory underneath his mansion, the metalbender officer was one of several who accompanied them. Once they were inside the factory, Hiroshi revealed himself to be an Equalist and began to attack them with a group of mecha tanks. This officer and several others attempted to subdue the tanks with their metalbending, but they were quickly defeated as the tanks electrified their cables. They were then loaded into various trucks and delivered to an Equalist prison to have their bending removed by Amon.
Sometime later, Team Avatar, Lin Beifong, and Tenzin managed to infiltrate the Republic City tunnel network leading to the Equalist prison, believing Korra to have been imprisoned there as well. Although Korra was not there, Lin found and freed a group of imprisoned officers, this particular officer included. When asked if she was too late, the metalbender officer solemnly affirmed that he and the other officers had had their bending taken away before she had arrived. He and the other officers escaped with Tenzin, Lin, and Team Avatar shortly thereafter.
