|“||Your mother asked for my blood. She said nothing of the dark magic that would turn you into a monster!||”|
Tatia was a member of the Petrova Family.
During the Middle Ages, Tatia lived in a small village with a child and a husband. However he died in battle but instead of throwing herself on his funeral pyre as expected of a Viking widow, she instead decided to move on and try to find love again. Later in time, she met both Elijah and Niklaus, both of whom fell in love with her. However she eventually chose Elijah. Esther, the mother of Elijah and Niklaus, used her in the spell to create the Original Vampires, with her blood as part of the wine laced with blood Mikael had given his children.
When Klaus had activated his werewolf gene and became a hybrid he went on a rampage in wolf form. When he awoke the following morning he was tended to by Elijah unbeknownst to them Tatia had followed them to see what happened. Seeing all the carnage created by Klaus she ran from them in fear and was pursued by Elijah. She had tripped and fell while trying to flee and cut her hand. The blood made Elijah lose control and attack her. She tried to defend herself but was no match and was killed. Elijah brought her corpse to a shocked Esther who used her blood as part of the spell used to bind Klaus's werewolf side, which resulted in Klaus's werewolf gene being dormant. Elijah then repressed the memory of how she actually died believing he had compelled not killed her in the woods and that Esther killed her when performing the hybrid curse.
Throughout The Vampire Diaries
Tatia was mentioned by both Klaus and Elijah during the second season. The first reference of her was presented in the episode Klaus, where Elijah was introduced to Katerina Petrova. Elijah says, "I'm sorry, you remind me of someone." In the same episode, Niklaus tells Elijah about "love" being a vampire's biggest weakness when Elijah tells Klaus about having feelings, caring and humanity. Klaus says that vampires do not feel and they do not care but then Elijah mentions about Tatia by saying "We did once" to which Klaus replies by saying "It`s too many lifetimes ago to matter."
In Bringing Out The Dead, Niklaus and Elijah reveal about their past with Tatia. They both reveal that they loved her and fought for her. Every man desired to be her suitor even though she already had a child by another man. It is also revealed that it was her blood which was laced in the wine they drank before getting killed by Mikael and leading to the creation of The Originals. She doesn't have an flashback appearance.
Silas and other characters make reference to that all doppelgängers (except Elena Gilbert and Stefan Salvatore) have died. It was indicated by Markos later in the season that Tatia was deceased, because Elena and Stefan were the last remaining doppelgangers living following the death of the last remaining Silas doppelganger.
Throughout The Originals
In Apres Moi, Le Deluge, Elijah mentions her and Celeste.While telling Hayley he has loved two women in the last thousand years.
In Gonna Set Your Flag On Fire, She appears again in a flash of Elijah's memory. Because of this flash Elijah almost attacks Cami.
In Brotherhood of the Damned, Elijah tells Cami that him and Tatia were in love. He also tells her he accidentally killed her. He also mentions Klaus was in love with her too. Elijah finally tells Klaus he accidentally killed Tatia. Klaus even though he was angry at his brother forgave him for this.
She was described as the most pure out of all the Petrova doppelgängers.
Tatia was a beautiful young woman with an oval face, almond-shaped brown eyes, and smooth, long dark brown hair which has many braids in it. Her height was about 5'7" and she had a slim, slightly athletic physique. Tatia was exactly physically identical to her distant ancestor Amara, and her descendents Katerina Petrova and Elena Gilbert. In The Reckoning, Rebekah said to Elena that the first doppleganger (Tatia) was much prettier.

||The Originals Season 1
- Tatia is of Russian and Latin Origin, and the meaning is "founder".
- The Ancient Roman form Tatius is the male verison of Tatia which both the Latin and Russian forms Tatianus and Tatiana are variations of.
- In Bringing Out The Dead, Elijah Mikaelson mentioned that they met Tatia after they moved to the new world. That indicates that she was born in the new world.
- She is the fifth character that Nina Dobrev played in the series.
- She is also the fourth doppelgänger that Nina played.
- Her blood was used as part of Klaus's hybrid curse, which Esther had put on him and it was her blood which was used in the creation of the Original Vampires.

- Tatia, like Elena Gilbert, was born in the area of the town that became Mystic Falls.
- They are the only Petrova doppelgängers who were born in Mystic Falls.
- Esther used Tatia's blood to turn her family into vampires. She later used the same method using Elena's blood to turn Alaric into an Original.
- It is most likely she either found peace or was sucked into oblivion when the Other Side collapsed.
- It was mentioned in Red Door that she was a widow. Her husband could possibly have been a doppelganger of Silas.
- If her husband was a doppelgänger of Silas, it would signify that none of the Originals know him as they would know that Stefan is a doppelgänger too.
- She was aware of Magic evidently because she knew that her blood was going to be used in a spell.
- Tatia didn't realize the dark magic used when Esther asked for some of her blood would turn Elijah into a monster, causing her to be afraid of him. This occurred after coming across the remains of all the villagers that were killed by Klaus' first transformation into a wolf.

- She was killed by Elijah but Esther took the blame, to save her son.
- Elijah and Klaus both hated Esther because they thought she killed her.
- Tatia is the only known doppelgänger in the series to not make a modern day appearance.
- Since her doppelgängers Katherine and Elena are both born in the month of June, it could be assumed that Tatia is also born in the same month as them.
