In her early life, Katherine was a young and beautiful girl who was punished by her family for having a child out of wedlock. Initially named Katerina, she had loved her daughter very much and was heartbroken as she was taken from her and she never even got to held her. After she was banished from Bulgaria, she relocated to England and seemed quite capable of making independent and intelligent choices. Katerina was characterized as a caring and polite person. She was quick to adapt to her relocation and enjoyed socializing and playing games with others. Katerina was also known to fall quick for men and yearned to be in the affections of others, even declaring to Elijah that life was not worth living if they did not believe in love. Despite her banishment from Bulgaria and estrangement with her relatives, Katerina maintained affection for them and was particularly close to her mother.

Despite her innocence and naivety, Katerina had a sense of self-preservation and immediately sought to protect herself against Klaus by stealing the moonstone and escaping the ritual that meant her death in the process. She had sought out vampires, Rose and Trevor for assistance, but betrayed them by consciously deciding to become a vampire herself for survival and igniting Klaus's wrath upon them all.

Perhaps one of the most marked differences in Katherine's actions is her increased openness with her true emotions and vulnerability, particularly with Stefan. As she was dying of eventual old age after Silas drained The Cure out of her, Katherine falls into a depression with her loneliness and impending death to point she briefly lost the will to survive. Her misery climaxed into a suicide attempt by jumping off a clock tower, but failed when Stefan saved her. However, Katherine's inspired with a will to live through the recent support of Stefan. She becomes emotionally dependent on him in her darkest hours and quickly fell in love with him again, admitting that he was the only reason she wanted to live. Katherine's softer sides are made more obvious than ever before, wondering to Nadia if she could be redeemed for her past misdeeds and is worthy of forgiveness; a sharp contrast from her vampire self who had no remorse over anything and justified it as means to survival.

The only humans that Katherine, as a vampire, has seemed to not view as mere collateral damage were Damon and Stefan, whom she lived with in 1864. Although her relationships with both brothers seem to have had a certain amount of manipulation and scheming involved, Katherine demonstrated both before and immediately after Stefan's transition-death that she genuinely cared for him. Her relationship with Damon does not appear to have had the same depth of such feelings, but she cared enough about him to want to turn him into a vampire. Still, her behavior around the Salvatores was so wrapped up in whatever her ulterior motives happened to be that it's not always clear where the selfish manipulation ended and the genuine affection began.

Katherine's attitude toward vampires does not diverge far from her attitude toward humans; she merely has to be more clever in how she manipulates them. She was willing to sell out those she considers friends, like Pearl and the other vampires in Mystic Falls at the time. She regards werewolves to be little better than humans: she only deals with George Lockwood in order to procure her escape from Mystic Falls in 1864, and uses Mason Lockwood and Tyler Lockwood in her plan to strike a deal with Klaus. She deals with witches with a bit more wariness, though her arrogance sometimes gets the better of her. Although she apparently lived with Emily Bennett for years and treated her as a confidante, she betrayed her during her escape from the town. Later, Lucy helps Katherine to repay a debt, but Katherine underestimates the witch's willingness to turn against her after the debt is paid.

Katherine's attitude towards the lives of others has been significantly influenced by the end of her human life and how her vampirism affected her family. She suffered the heartache of being separated from her illegitimate daughter and disowned by her family, and not long after suffered the despair of finding her entire family dead, brutally murdered by Klaus. Any trace of the human girl who still believed in love seemed to evaporate after this last great loss, though it peeks through occasionally when it comes to Stefan.

Overall, Katherine has no respect for anyone's life but her own, and will not spare a life unless it suits her interests to do so. Although she has risked her life in the past to save Damon and Stefan, doing so was in the context of repaying a debt and killing Klaus, it remains untested whether her affection for the brothers could ever truly transcend her sense of self-preservation.

History:
Katerina Petrova (Cyrillic: Катерина Петрова) was born into a noble and wealthy Bulgarian family on June 5, 1473. In 1490, when she was 17 years of age, Katerina became pregnant by an unknown man, a Traveler, 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 and gave the child to another family, claiming it would be better for both of them to never see one another. Katerina was devastated by this and was banished to England, where she admitted to "quickly becoming English." In 1492, she met Trevor, who introduced her to Lord Elijah, who in turn introduced her to his younger brother, Lord Niklaus. Katerina was attracted to Klaus, until she found out what he was, and that he was planning on using her as a sacrifice to break the the Hybrid Curse placed on him. She escaped with the help of Trevor, who had fallen in love with her. He led her pursuers astray and told her to go east to a cottage in the woods where she would be safe. When she arrived at the cottage, Katerina met a vampire named Rose.

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 back to Klaus as soon as the opportunity arose, not wanting to suffer Klaus' wrath. Katerina tried to commit suicide by stabbing herself with a knife, saying she would rather die than go back to Klaus, but Rose force-fed her some of her blood to heal her. When Rose turned her back to confront Trevor, Katerina hung herself with a length of rope. And that is how she became a vampire.

Katerina returned to Bulgaria in the latter months of 1492 to find her entire family brutally slaughtered by Klaus. She knew he had done it as revenge for her escape and subsequent transition. She was last seen weeping over her mother's dead body.

Katherine may have stolen the spell for making Daylight Amulet's from Esther's grimoire before fleeing from Klaus as this may explain how Emily was able to make Katherine, Bethanne, Pearl, Anna and Harper daylight rings and her a necklace in 1864.

Sometime during 1498, Katherine returned to Bulgaria after escaping from Klaus. Katherine searched every village and cottage for her daughter, Nadia Petrova, who was eight at the time, but had no luck in finding her.

When Katherine learned of the escape of the Tomb vampires, she gave her descendant and friend, Isobel, a Lapis Lazuli medallion, enabling the young vampire to walk in the sun. Katherine needed the tomb vampires dead because she didn't want Klaus to find out she was still alive, so she had Isobel retrieve Johnathan Gilbert's invention and give it to John Gilbert to use against the vampires in Mystic Falls. This resulted in the deaths of the remaining tomb vampires.

After she died, and the hell was reopened she escaped and now she is a vampire again. She decided to live in Forks so no one would know she is alive.
