~Mileena~
Created by the sorcerer Shang Tsung, Mileena has at last fulfilled her destiny as Kitana's successor by posing as the former princess. She misleads Kitana's military forces in an attempt to give the Dragon King the time he needs to complete his plans. Only Baraka knows the truth behind her deception.

~Sonya Blade~
An officer of the Special Forces in Earthrealm, Sonya Blade came to Outworld at Raiden's request to kombat the Deadly Alliance and to locate and rescue two of her missing agents. Though she never found them, she took part in the assault on Shang Tsung's palace.

~Kitana~
Princess Kitana successfully freed her realm of Edenia from the Emperor Shao Khan only to be threatened by his former subordinates, Shang Tsung and Quan Chi. She fell in battle against their Deadly Alliance only to be ressurected by the Dragon King. Kitana now serves as one of his personal body guards.
