- Deadly Alliance: "The vampire Nitara had at long last discovered the location of the Orb that bound her realm to Outworld. Unfortunately, it rested in a location she could never access. However, the ninja cyborg Cyrax of Earthrealm had the ability to retrieve it for her. Through careful manipulation, she convinced Reptile to engage Cyrax in combat and destroy his arm panel in the process. The damage to his transporter left him stranded in Outworld. Her plan was coming together beautifully. Nitara offered to send Cyrax back to Earthrealm if he could retrieve the Orb from its hiding place. Nitara carried a gemstone around her neck. These gemstones made it possible for her people to traverse the realms. They had done so for ages and had even visited Earthrealm regularly in search of blood. Cyrax had no choice but to accept the offer and journeyed with her to the presumed location of the Orb. As they traveled across Outworld, however, they had the strange feeling that they were being followed."
- Bio Kard: "A vampire from a forgotten realm, Nitara fights to keep her homeworld independent. Years ago, her realm was fused with Outworld, throwing it into chaos. Now that her homeworld has been freed, she struggles to maintain its fragile stability."
- Armageddon: "The realm of Vaeternus had regained independence from Shao Kahn. I was revered for my part in the victory. The restructuring of our civilization was well underway; soon we would regain our former majesty. Unfortunately our honor was not all that had returned from ages past.... Reports of genocide raced throughout the restored Moroi Empire. Many vampires had been slain; none had yet survived an attack to describe the assailants. I set forth to uncover the truth. Examining the wounds of the dead, I came to the disheartening conclusion that these murders were not the work of a band of assassins. The victims had fallen to the blade known as Datusha, the bane of the Moroi. The ancient kris's had found a new wielder. It had returned for vampire blood. Though Datusha's origin has been lost to history, its purpose is clear: It lives to kill as many vampires as it can. We are a powerful race; there are few who threaten our immortality. It has been speculated by the Elders that the sword itself may be our one "natural" predator. The accursed blade finds a wielder and corrupts them into believing they are slaying for some higher purpose. In the past it has chosen a vampire as its puppet. The last was Kahil Grigesh. Though he was driven mad by the power of the sword, he was strong enough to eventually overcome its mind control. To atone for slaying his fellow vampires, he took the sword into the Netherrealm, where he committed hara-kiri, imprisoning Datusha in Hell. It was believed that the sword would never find another vampire wielder in that desolate place. Safe from slaughter, our numbers had exceeded those of any recorded era. But with Datusha's return, vampires were being rapidly driven to extinction. Something needed to be done! The Elders researched ancient vampire texts, hoping to find some means of defeating the blade. An obscure Edenian prophecy they found might hold the key. It describes a force of great power concealed in a crater there. I was commanded to find this power and use it against our foe."
Nitara spent a very long time trying to find a mysterious orb that bound her realm to Outworld before actually discovering its location. The orb, however, was inaccessible to her, submerged under molten lava. Fortunately for her, at one point she had spotted the Outer World Investigation Agency agent Cyrax traveling across Outworld. With his cybernetic body, he would be able to descend into the lava and come back with the orb, unharmed.
But she realized she would need to offer the cyborg something in exchange for his services. Seeing Reptile as an easily exploitable fool, she presented him with a Kirehashi blade, an artifact of Reptile's home realm Zaterra, and revealed to him the location of Kitana's military encampment. After Reptile discovered the dead body of Shao Kahn, he offered his services to Nitara, grateful for her apparent kindness. He pledged to serve her, and she commanded him to attack Cyrax, describing him as an Earthrealm invader, and explaining he could be weakened by destroying his arm console, which Nitara was aware the cyborg used to travel between realms.
Reptile did as instructed, and fled after being frightened away by one of Cyrax's attacks. Nitara introduced herself to Cyrax immediately after, and made her proposal: having the ability to traverse realms through the powers of her gemstone, she would send him home, under the condition that he retrieve the orb for her. Although hesitant to trust her, Cyrax accepted, having little choice. The two journeyed to the orb's location, Onaga's incubation chamber. There, both parties held up their end of the bargain: Cyrax descended into the lava and retrieved the orb, and Nitara sent the cyborg home. With the orb in her hands, her plans had come to a successful conclusion. She then smashed it into pieces on the floor, separating her realm from Outworld at last. The ordeal knocked her unconscious, but when she awoke, she was home. She then made it her mission to protect the realm's fragile stability.
During the events of Mortal Kombat: Armageddon, mass genocides of her people began to occur in her realm. The wounds on the bodies indicated that the attacker used a mystical kriss known as "Datusha", which is described as existing solely to slay vampires. Nitara is sent by her people's elders to a crater in Edenia so as to find a prophesied force of great power that would be able to destroy the blade. While traveling there, she came upon the demon Ashrah, the possessor of Datusha who was slaughtering vampires in the belief that it was purifying her soul. To protect the rest of her race, Nitara defeated Ashrah and continued on her journey into Edenia, planning to lure her attacker to the Edenian weapon where it may be used against her.
Nitara would join the Forces of Darkness in the final battle and die alongside the rest of the kombatants.
- Deadly Alliance (Canonical): "After what seemed like an eternity, Cyrax finally emerged from the lava, holding the Orb that had bound Nitara's realm to Outworld for ages. At last it was within her grasp. She would be able to free her people from Shao Kahn's imprisonment. Fulfilling her end of the bargain, she sent Cyrax back to his Earthrealm home in exchange for the Orb. Nitara stared into the Orb. It seethed with the power trapped within. She raised it above her head, and then smashed it to the floor. It shattered with an inhuman, soul-rending howl. Its horrible energy exploded away, and tore her consciousness from her. She awoke later for the first time on her native soil."
- Armageddon (Non-Canonical): "The gift of godlike power transformed Nitara into a blood god. Horrified, the kombatants fled from the pyramid, but none were spared her wrath. Beginning with Shao Kahn, she mutated each of them into her vampire slaves. With the most powerful warriors in the universe at her command, Nitara and her unstoppable army easily conquered the realms."
