Zuko is skilled in "Dao duel-wielding," as in the episode "The Blue Spirit" wherein he withstands a large number of adversaries. In "Avatar: The Lost Adventures," it was revealed that he studied under Master Piandao, his uncle's colleague and Sokka's master sword fighting instructor. Zuko has also demonstrated an ability in stealth and unarmed combat, as when able to infiltrate a Fire Nation fortress, the Northern Water Tribe's city, and the Dai Li's base in the Earth Kingdom without detection. His proficiency at stealth was also utilized during the episode "The Southern Raiders" in which he and Katara stalked and cornered the former commander of the eponymous Raiders in his home village without revealing themselves. Avatar Extras revealed he has abnormal hearing and that he is also naturally gifted at playing the Tsungi horn (though he is never heard playing).
