Why Iroh Isn’t The Firelord In Avatar: The Last Airbender, Despite Ozai’s Age

In Avatar: The Last Airbender, Ozai is the villainous leader of the Fire Nation who opposes the Avatar’s mission to balance the world, but their birth order indicates that it should have been his older brother Iroh on the throne. Initiated by their grandfather Sozin, Fire Nation is in the midst of a century-long war with the rest of the world. Unlike his peaceful brother Iroh, Ozai is deeply committed to completing the Fire Nation’s takeover of the remaining nations.
