As the daughter of Edenia's ambassador to the new realms, Tanya invites a group of refugees fleeing their own world into the safety of Edenia. But soon after queen Sindel allows them through the portal, she learns that one of the warriors is none other than the banished elder god, Shinnok. The portal leads into the pits of the Netherrealm itself, and the once free realm of Edenia is new at the mercy of Shinnok.

I had been called an enforcer of the Deadly Alliance. I preferred the term "ambassador". It was my duty to impose the will of Quan Chi and Shang Tsung upon the denizens of Outworld. But the sorcerers' rule was short-lived and I found myself leaderless, longing to return to my birthplace in Edenia. When Baraka caught up with me, he gave me a choice: Serve his new lord of Outworld - or die. I have lived for thousands of years because I make the right decisions. I pledged my service to the Dragon King.

Onaga was aware of Shao Kahn's invasion of Edenia so many years ago. Apparently the Dragon King had been watching Shao Kahn from beyond death. Whatever the late emperor had been attempting, Onaga was determined to complete it. He was looking for lost information, ancient spells that would fuse the Elder God's six kamidogu into one and therefore make it possible for him to wield their combined might. I brought him to Edenia, where I believed that information still existed.

Like Kitana and Rain, Tanya is an Edenian, a native of a realm konquered by Shao Kahn and merged with Outworld millennia ago. The Edenians have been fighting for independence ever since. Though she's a skilled kombatant, Tanya prefers more subtle means of achieving her goals. Most recently she and Rain have allied with the ousted former Outworld empress, Mileena. Tanya and Rain will help Mileena regain her throne in exchange for the creation of a new Edenia. What will become of Tanya's relationship with Mileena thereafter, none can say...

Chosen as an infant from Outworld's first-born daughters, Tanya was raised by the Umgadi's priestesses. She's never known her birth family.

As she grew older and saw other initiates wash out, Tanya feared that she would share their fate. But that fear spurred success; after many attempts, Tanya passed her trials and became a full Umgadi.

Over time, Tanya became one of the order's most trusted members. She was the obvious choice when it needed to choose a new leader for the royal family's personal guard.

As an Umgadi, Tanya is sworn to piety and chastity. That is why her bond with Princess Mileena, were it known, would cause a scandal. By following her heart, Tanya risks not only her position but also her life.

Tanya: Follow me Liu Kang. Raiden has asked that I lead you to him.

Liu Kang: What about the others?

Tanya: He has something special planned for them.

Liu Kang: Tanya... what's going on?

Tanya: HA HA HA HA!

Tanya: I don't know what Kitana saw in you? Can't you see Liu Kang? This is a trap!

Liu Kang: What...??

Quan Chi: Welcome Shaolin Warrior. Your Thunder God is beaten. Earth's warriors destroyed. You are the last remnant of the Forces of Light. Do you wish to beg for mercy from your new master the Lord Shinnok?

Liu Kang: Never sorcerer!!!

Liu Kang: WAAAHHHHHHHH!!!

Shinnok: Fool.

Quan Chi: Hahaha!

In Edenia, Tanya had located the ancient texts that described the process by which to fuse the Kamidogu into one. With this information, Onaga was able to create the One Kamidogu - a tool of unspeakable power.

As the Dragon King was distracted, reveling in his victory, Tanya seized the opportunity to snatch the Kamidogu from him, thereby obtaining god-like power. She destroyed the Dragon King and became Ultimate Overlord of the realms.

The fire of Blaze transformed Tanya into a being known as a Dragon Caller. With a mere thought, she was able to summon dragon spirits from the ether into corporeal form. With an army of dragons at her command, she conquered the universe realm by realm. Soon Shao Kahn himself would call her 'master'.

With Mileena executed, Tanya's dreams of a free Edenia seemed dead as well. She and the other rebels were fugitives from Kotal Kahn's justice. Her fellow Edenian Rain had proved a powerful ally and a satisfactory konsort. But he had become useless to her. In exchange for leniency, Tanya informed the Kahn of Rain's whereabouts. Imprisoned but alive, Tanya's plotting began anew.
