Kung Lao's Death

Kung Lao decided not to return to Shaolin, instead allowing everyone to believe that he was dead and went on to live a life of peace in respect to the beliefs of his ancestors. This would not last long however, as he was drawn away from his newfound peace to help fight against Shinnok's forces, when word reached him that Goro was still alive. After Shinnok's defeat, Kung Lao attacked Goro, who had signed a peace treaty with the Centaurs under the mediation of Kitana. Instead of being an attempted assassination, however, the blow was a ceremonial strike of vengeance for the Great Kung Lao's death. With this act, the two warriors shook hands, ending their conflict.
The next years were peaceful. This ended on a brutal note at the time of Mortal Kombat: Deadly Alliance, when the sorcerers Quan Chi and Shang Tsung united and murdered Liu Kang in a vicious attack. Kung Lao found his body and was told by Raiden that Tsung was the assassin, who had formed the Deadly Alliance with Quan Chi. Enraged, Kung Lao vowed revenge upon the sorcerer, and once again abandoned his pacifist Shaolin beliefs. He believed his current skills were insufficient to defeat Shang Tsung so after meeting with the other Earthrealm warriors and traveling to Outworld. Kung Lao informed Kitana of Liu Kang's death and she tagged along with Kung Lao and sought the advice of the martial arts teacher Bo' Rai Cho, who trained Kung Lao for a short time. Together, they joined the other warriors in the assault against the two sorcerers.
But the assault did not end well and, with Liu Kang dead, Raiden and his companions were fighting a losing battle. Kung Lao and Kitana challenged the Deadly Alliance. Kitana would fall against Quan Chi and Kung Lao would fall to the hands of Shang Tsung, leaving only Raiden to battle the Deadly Alliance.
