List of Avatar: The Last Airbender characters
Iroh (Mako in season one and two. Greg Baldwin in season three) is a retired Fire Nation general, known as the Dragon of the West, and Prince Zuko's uncle and mentor. Iroh was the original heir to the Fire Nation throne, though his brother usurped it after their father's death. On the surface, Iroh is a cheerful, kind, optimistic, eccentric, tea-loving old man, but he still remains a powerful warrior and is also a devoted surrogate parent to Zuko. Iroh is a Grand Master of the Order of the White Lotus, a secret society of men from all nations and helps retake Ba Sing Se during the series finale. Unlike most Firebenders, Iroh does not use anger as the source of his strength; instead he uses the original Firebending skills learned from the Dragons.
