Zuko is highly skilled in Firebending which utilizes Chinese martial arts techniques of Changquan, Shaolinquan, Lóng Xíng Mó Qiáo and Xing Yi Quan. The series' creators consulted a professional martial artist in the design of the show's fighting style. Firebending represents the element of power, and is categorized as the most aggressive of the "four bending arts." Firebender discipline stresses self-restraint and breath control as a means of directing and containing the fire manifested. Poor breath control means dangerously poor control of any fire generated. For this reason, breathing exercises are one of the most critical first steps for beginning firebenders.
