Qin

The cunning and inventive Qin oversees the creation of all the Fire Nation’s war machines. Qin has been a Fire Nation emissary for years and has worked with The Mechanist to create destructive tanks and warships. He also has several secret weapons in the works in an effort to bring an end to the war. And now that he has possession of the mechanist’s war balloon, the Fire Nation could soon control the skies, as well as the land.

For several years, War Minister Qin has been developing the massive drill used to attack Ba Sing Se. Despite being defeated twice by the Avatar, the War Minister is still a valuable part of the Fire Lord's cabinet due to the technological advancements he has brought to his country.
