Early History



Katerina Petrova was born into a wealthy Bulgarian family on June 5th 1473. In 1490, when she was about 16 or 17 years of age, Katerina became pregnant by an unknown man, and her family disowned her for the shameful birth of an illegitimate daughter. She carried the child to term, but seconds after her daughter's birth, Katerina's father took the child away, claiming it would be better for both of them to never see one another again. Katerina was devastated by this and was banished to England, where she quickly adjusted by becoming English. In 1492, she met Trevor, who introduced her to Elijah, who in turn introduced her to his younger brother, Niklaus and younger sister, Sophia. While spending time with the brothers and sister, she quickly fell for Elijah and was possibly in a relationship with him. She also became fast friends with Sophia. She was possibly attracted to Klaus until she found out what he was and what he wanted for her. He wanted to kill her so he could break the sun & moon curse and to do that you need a Petrova doppelganger, which Katherine was. Sophia told Katerina to run.

When Rose found out that Katerina had escaped from Klaus with the moonstone, she locked her in a room and told her that she would take her to Klaus as soon as the opportunity arose. Katherine tried to kill herself by stabbing herself but Rose fed Katherine her blood to heal her. Rose then walked outside the room to talk to Trevor while Katerina killed herself. Trevor asked why she did it and claimed he would have helped her live. Katerina responds by saying that he would have been able to help her run and that running was never going to be enough. Shortly after becoming a vampire, she returned to her family but only to find them killed by Klaus because of what Katerina had done by killing herself, so Klaus got revenge by killing her whole family. She was last seen weeping over her mother's dead body. She was reunited with Sophia whom stayed by her side.


Sometime during 1498, while Katherine was back in Bulgaria after escaping from Klaus, she began her search for her daughter in every village and cottage with the help of Sophia. They had no luck in finding her.

"Many people call Katherine evil but to me...she has a big heart."
—Sophia about Katherine

Some people say she's a mean and manipulative. She's a good actress. She acted like Elena Gilbert many times. Sometimes she can be good and let her humanity show. She is a miasma of sorrow hidden by centuries of bad behavior. Katherine is an independent and strong-willed woman. She relies only on herself and Sophia. People know she's a force to be reckoned with. While some may call Katherine evil, some think she's a pretty powerful woman and wouldn't mind her having on their side. She often shows her kinder and delicate side to Sophia but is still able to keep her bad girl image.

Physical Appearance


Katherine is an extraordinarily beautiful and seductive young woman: she has an oval face with fine bone structure, a wealth of brown curly hair, and almond-shaped, deep brown eyes with thick dark lashes. Katherine favors a curly hair style, Katherine often pairs a sensually cut outfit with heels, and Katherine tends to wear a lot of makeup.

Katherine's eyes seem to be a shade darker, having a smoky, shadowy appearance; Her mannerisms are more deliberate, almost as though she is performing for her audience - a skill that comes in handy when she wants to borrow the identity of the younger doppelgänger, Elena Gilbert. Even her speaking voice seems harsher, more cutting than Elena's.

Her tank tops are tight-fitting, and most have v-necklines and rouched chest details, making them very figure-flattering. She wears them in black, grey, blue, purple, and green. Katherine is always dressed in sexy black skinny pants and leggings. Katherine wears black leather and cotton jackets, the majority of which have rounded collars and puffed shoulders. She adds more sex appeal to her outfits by wearing suede and leather stiletto booties in black.

Whenever Katherine pretends to be Elena she dresses very similar to Elena's style and straightens her hair.
