Taja is a feisty charmer with an irreverent gleam in her eye. She is a sexy and proficient professional thief, con artist, and schemer who gets by on her ability to tap into whatever is necessary to disarm her marks. Even when caught, Taja smiles boldly, confesses her crime and somehow is let off the hook.
Taja was born into a nice, but not wealthy, European family. As a child, she and her less than traditional family traveled to the Far East. There her parents provided a wonderful and fascinating though not opulent life for her. At the age of 12, Taja's parents mysteriously disappeared and were later found dead. Left on her own, Taja learned to survive by her bold charm and swift cunning.
When Taja was a young girl in her early teens, she belonged to a family of travelers. They were not a very wealthy family, but they were happy nonetheless. But one day while her family were setting up camp in the middle of a forest, Taja wandered off exploring, not realizing that she would never see them again.
Taja used the only talent she knew to survive: stealing. Sometimes Taja would have to go extremely out of her way to achieve something. Her youth did not set a limit for her, and she would sneak into a king's palace if necessary. As she grew up, she became one of the most sly and skillful thieves in the world. But along with stealing, she picked up the ability to fight. Fighting was essential for thieves, for even the most silent of burglars occasionally get spotted. One day Taja teamed up with other thieves in an attempt to mug the local Baron Reyland's daughter, Jen Reyland and her bodyguard, Siro. Unfortunately, Siro defeated both of them and even managed to arrest Taja, who was sentenced by the Baron to work as a slave. The Baron attempted to initiate an intimate relationship with her, but thankfully Siro stepped in before the Baron could take Taja by force.
Meanwhile, a man named Kung Lao had also been in trouble with the Baron for attempted romance with Jen. The Baron hated the idea of Jen being married to the latest champion of the Mortal Kombat, thinking it is nonsense and an unsuitable lifestyle for his daughter. It is revealed in the episode "Debt of the Dragon" that the Baron owed a lot of money to the Black Dragon Clan and probably wanted Jen to wed a wealthy man to help pay it off. In one last attempt to free Kung Lao, Jen freed Taja, seeking her help. Taja defeated all of the Baron's guards single-handedly, allowing Kung Lao to escape from danger. Things went wrong again, though. A lethal assassin named Scorpion captured Jen in the hopes of luring Kung Lao to a battle.
By this time, Taja had become friendly with both Siro and Kung Lao and joined them on a mission to rescue Jen. While Taja and Siro fought the monks who had been cursed by Scorpion, Kung Lao battled him in the Shaolin Temple of the Order of Light. Taja helped Kung Lao and Siro in destroying Scorpion, but the win was more of a loss, as Jen's dead body lay burned on the floor. In later episodes Taja explains how unusual it was for her to make friends and constantly faces betrayal from many whom she thought to have trusted. During 'Twisted Truth' she forms a romantic relationship with Tomas, to which Kung Lao and Siro believe him to be a murderer, but at the end Tomas proves his loyalty to Earthrealm by sacrificing himself to save the three. Taja is also betrayed by an old comrade thief from days past (in episode 21) and earlier when she was kidnapped by Shang Tsung she begins to feel sympathetic about Vorpax's lifestyle, but later is betrayed by the woman upon learning what Queen Kreeya's true plans were about.
Taja lives with Siro and Kung Lao at the trading post in Zhu Zhin, which once belonged to the late Baron and Jen Reyland. Frequent attacks have been made on the three warriors. As the champion, Kung Lao must be wary as the furious fighters of Outworld try to annihilate Earth's only hope. Taja's unique martial arts abilities and sneaky theft skills lend a massive helping hand to her friends as they stand fighting for their realm. In the final episode, it is shown that all of the main characters are dead, including Taja. However, since the series was never finished and, according to the producers, this episode was supposedly going to be just a dream, leaving Taja's ultimate fate unclear.
- It is a possibility that Taja can be a direct ancestor of Johnny Cage, due to her relationship with Tomas, who bears a striking resemblance to Cage.
