Metang was a member of the Southern Raiders in two separate stints. He served from 77 - 100 AG and then again during its brief revival in 102 AG. Starting in 96 AG, he was appointed commander following the retirement of Yon Rha, where he had his first encounter with Katara after she mistook him as her mother's killer.
Following the Hundred Year War's end, Metang left the Fire Nation Navy after Fire Lord Zuko disbanded the Southern Raiders. After a year living at home and drifting from job-to-job, Metang returned to a newly-organized Southern Raiders after getting the word from Zhei Li that a new plan to raid the Southern Water Tribe was being formulated. However, this raid ultimately failed, and Metang was returned to the Fire Nation and executed on Zuko's command.
