Iroh

Iroh was a retired Fire Nation General, a Grand Lotus of the Order of the White Lotus, a former Crown Prince, a firebending master, and the uncle of Zuko. Iroh mentored and watched over Zuko. As a firebending master, Iroh earned his repuation by his ability to breathe fire, which earned him the title "The Dragon of the West". Iroh and his nephew, Zuko, traveled all over the world to find the Avatar and put an end to him so the Fire Nation could rule over all nations.
