An enigma to all who come into contact with him. Ermac's past remains shrouded in mystery. It's believed that he exists as a life force brought together by the souls of extinguished Outworld warriors. Shao Kahn has managed to take possession of these souls and use them to fight on the side of tyranny.

When the renegade Princess Kitana makes her escape into the unknown regions of Earth, Jade is appointed by Shao Kahn to bring his daughter back alive. Once a close friend of the Princess, Jade is faced with the task of betraying her friend or disobeying her Emperor.

Kitana is accused of treason by the High Courts of the Outworld after murdering her evil twin Mileena. Shao Kahn takes it upon himself to appoint a group of warriors specifically to catch his daughter and bring her back alive. But Kitana must find a way to reach the newly crowned Queen Sindel first and warn her of their true past.

Murdered by her twin sister Kitana, Mileena finds herself brought back to life by Shao Kahn himself. Her skills as a vicious fighter will be needed to defeat Earth's chosen warriors. Her ability to read the thoughts of her twin sister will enable Kahn to stay one step ahead.

Born of Kitana's former world of Edenia, Rain was smuggled away from the realm as a small child shortly after Shao Kahn's take over. Thousands of years later he resurfaced. His allegiance belonging to Kahn, he chose to betray his homeland rather than suffer at the hands of Kahn's extermination Squads.

Always a reliable servant to Shao Kahn, Reptile is chosen to assist Jade in the capture of Kitana. In contrast to Jade's instructions, Reptile is ordered to stop the renegade Princess at all costs... Even if it means her death.

When Shao Kahn makes a failed attempt at stealing the souls which occupy Earth's hell, Scorpion is able to escape from the nether region. Free to roam the Earth once more, Scorpion holds allegiance with no one. He's a wild card in Earth's struggle against the Outworld.

In his human form, Smoke was a lethal assassin working for the Lin Kuei. But when they decided to automate their ninjas, Smoke is caught in the middle. He became a cyborg assassin, whose human form would exist as a memory forever more.

Thought to have been vanquished in the Shaolin Tournament, Sub-Zero mysteriously returns. It's believed this secretive member of the Lin Kuei, a legendary clan of Chinese "ninjas", has returned to again attempt an assassination of Shang Tsung. To do so, he must fight his way through Shao Kahn's tournament.
