Many centuries ago, Earth was an enchanting and desirable planet. Powerful and rich with natural resources, the vicious megalomaniac Shao Kahn wanted Earth as part of his growing collection of conquered realms known as Outworld. To protect Earth, Mortal Kombat was created: a tournament in which the fate of the planet is decided in battles between competitors from Earthrealm and Outworld. Five hundred years in the past, the monk warrior Kung Lao defeated Shao Kahn’s sorcerer, Shang Tsung. When Kung Lao spared his life, Kahn imprisoned Tsung in the cobalt mines.
Kung Lao now had to train the next generation of warriors, who would give their lives to save Earth. Kung Lao created a partnership and friendship between two warriors: Siro, a former bodyguard, and Taja, an ex-thief. In the mysterious city of Zhuzin, Kung Lao and his new friends are guided and watched over by the thunder god Rayden. The three now battle various evils of both Outworld and Earthrealm, including an imprisoned Tsung, who swore eternal revenge on Kung Lao for his humiliating defeat, and the sultry and seductive Vorpax, who is also imprisoned in the mines and has an agenda of her own.
