Shou-Lao is an immortal Chinese dragon who became the source of power in K'un-L'un. During a performance of the dragon riders of K'un-Lun for the entertainment of its Yu-Ti, Shou-Lao went berserk and attacked the city's leader. He was slain by Quan-St'ar who cut out the dragon's heart. Enraged at this, Yu-Ti banished Quan-St'ar from the city and revived Shou-Lao by melting his heart and placing it in a sacred cavern. Following this incident, those who became Iron Fist had to accomplish the final test of defeating Shou-Lao in order to absorb part of his power. This was done over 66 times. After she was busted for training three cavemen, Fan Fei was chained up and watched as the cavemen were fed to Shou-Lou by Lei Kung. When she broke out with the hope that she will die fighting Shou-Lou, Fan Fei punched Shou-Lou in his chest tattoo and gained his powers. When Danny Rand was becoming the next Iron Fist, he defeated Shou-Lao by burning the dragon-shaped tattoo off his chest. After defeating Shou-Lao, Danny Rand plunged his hands into the brazier containing Shou-Lao's immortal heart and it charged him with the power of the Iron Fist. Steel Serpent later attempted to fight Shou-Lao. When Steel Serpent failed to defeat Shou-Lao, Lei Kung found him weeping in the snow. He then took Steel Serpent back to the city. During the Avengers vs. X-Men storyline, the X-Men fought the Avengers in K'un-L'un when Hope Summers and Lei-Kung arrive on the back of Shou-Lao who blasted the Phoenix Force-empowered Cyclops. Unfortunately, Shou-Lao was far too young to put up a fight and its riders were dislodged. However, Hope was able to unleash a combination of dragon energy, fire, and chaos magic to banish Cyclops to the Moon.
