Iroh is a very powerful firebender—i.e., he has the power to telekinetically create and manipulate fire—and a retired general of the Fire Nation. He is the elder brother of Fire Lord Ozai, the ruler of the Fire Nation and leader of its campaign to conquer the other three nations. During the narrative of the series, he accompanies his exiled nephew Zuko on his quest to capture the series's protagonist Aang to restore the young prince's honor and birthright; Iroh acts as a mentor who seeks to help his nephew become a better person than his father.
