Zhao did not perish, but instead ended up in the Spirit World, forced to spend eternity in a place known as the Fog of Lost Souls. There, he spiraled into psychological instability, reveling in his self-proclaimed achievements for over seventy years after his defeat at the Siege of the North. When Tenzin, Kya, and Bumi entered the fog in search of Jinora, Zhao grappled with Tenzin, whom he mistook for Aang, in hope of regaining his glory by capturing the Avatar. Having realized Zhao to be delusional, the siblings wrestled him away and left him behind in the fog.[5]
