Humble, yet Epic. Peaceful yet willing to fight if needed. This old-timer has been around for a while and has been involved in a great war between the nations. He knows the consequences of battle (losing his son) and does his best to keep his nephew Zuko on a righteous path. But Zuko is torn between his father and his Uncle Iroh. A retired fire-nation general, he's skilled in the art of battle and strategy with his famous fire-bending. His voice should sound  old, wise and humble.
