**Katherine Pierce Mikaelson**, born **Katerina Petrova** *(**Bulgarian**: Катерина Петрова)* is a hybrid of vampire and witch, and a former main character of *The Vampire Diaries* and *The Originals.* She is a guest character in *Legacies*. She is also the second-known Petrova Doppelgänger of Amara. She was the main antagonist of season one (mostly off-screen through John Gilbert's and Isobel's actions, as both were working for her in order to kill off the tomb vampires). She later became a deuteragonist in season one, two, three, four, and five of *The Originals*.

In 1490, she was disowned by her father because she brought shame upon her family after giving birth to a baby girl out of wedlock when she was seventeen. She was forced to give the baby up for adoption and then was then exiled to England. She quickly assimilated into English culture and met two nobleman brothers, Niklaus and Elijah Mikaelson. At first, she was attracted to both men, but in time, she eventually learned that she was a Petrova doppelgänger and that Klaus was planning on using her as a sacrifice in order to break the curse that bound his werewolf side. She sabotaged his plan by running away with the moonstone, which bound the curse, and then tricked Rose into feeding her vampire blood so she could turn herself into a vampire. Because Katherine was no longer human, her blood no longer was a viable component of the ritual to undo the curse. Klaus was so infuriated with Katherine's sabotage, that she was forced to live on the run for over 500 years as he hunted her down.

Her activities during her first centuries as a vampire are unknown, but at some point between the 15th and 19th centuries, she took on the alias "Katherine Pierce" (an anglicized version of her birth name) and eventually met and befriended Pearl, Anna, and Emily Bennett. In the late 19th century, she traveled to Mystic Falls, where she met Damon and Stefan Salvatore, whose family hosted her at the Salvatore Estate. She later fell in love with both brothers, and subsequently fed them her blood, resulting in their eventual transitions into vampires after they were killed by their father in early autumn of 1864. When the Founder's Council found out the identities of the vampires in town, she faked her death and escaped being sealed in the tomb with the aid of George Lockwood, who helped her in exchange for the moonstone.

During the twentieth century, she continued to keep tabs on Stefan while still hiding from Klaus, including two separate sightings in Chicago in the 1920s and the 1980s. In 2010, she came back to Mystic Falls with the intention of finally earning her freedom from Klaus by handing over the Petrova doppelgängers who came after her, Elena and Alex Gilbert. To sweeten the potential deal with Klaus, she killed Caroline Forbes, who had Damon's blood in her system and later transitioned into a vampire, and tricked Mason and Tyler Lockwood into triggering their werewolf curses, just so they could each also serve as the vampire and werewolf sacrifices necessary in the ritual. She even tracked down the moonstone so that she could give Klaus every component necessary to break his curse. However, when her plans ultimately fell through, she fled Mystic Falls again shortly after Klaus broke his hybrid curse on his own, knowing that he was not done punishing her for her betrayal half a millennium ago.

After failing to induce Klaus' forgiveness by securing the cure and handing it over to Elijah in Season Four, Katherine managed to draw Klaus away from Mystic Falls by telling him that there was a witch plotting against him.

In *Graduation*, Katherine recieves a call from Alex saying that she forgives her. Katherine tells Alex that she's sorry for what she has done and that she's sorry that she betrayed a friend. Alex invites Katherine to New Orleans.

Since the forgiveness from her best friend she has never wasted having the life she wanted. Since then Alex has trusted Katherine with her life and her children's. She's helped Alex when running from Dahlia but eventually Dahlia and Klaus found them and put the curse on the Crescent pack.

Katherine's notable ancestors include Amara, who was Silas' true love and presumably the world's first immortal woman, and Tatia, whose blood was involved in the creation of the adapted spell of immortality that was cast on the Mikaelson Family by Esther, as well the curse that bound Klaus' werewolf side. She is also the maternal ancestor of Maria Flemming, Lilith Labonair, and Isobel Flemming and that of Isobel and Lilith's biological daughters, Arielle Labonair, Hayley Marshall, Elena Gilbert, and Alex Gilbert. She was once the romantic interest of Stefan and Damon Salvatore, as well as Mason Lockwood. Since the late 15th century, she has also been the romantic interest of Elijah Mikaelson, with whom she was involved in the 21st century.

**Katerina** is a member of the **Petrova Family**. She is also member of the **Mikaelson Family** through her marriage and has ties to the **Salvatore Family**, **Gilbert Family**, **Lescheres Family**, and **Labonair Family**.

## Early History

* 1473-1490's
* 1720
* 1864
* 1920's
* 1970's
* 1983
* 1987

Katerina Petrova (*Cyrillic: Катерина Петрова*) was born into a noble and wealthy Bulgarian family on June 5, 1473. In 1490, when she was about 16 or 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. Later, when Katerina woke up in transition, 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.

Rose then explained to Trevor that Katerina used him to escape, and, knowing Klaus would find out their role in the escape, Rose attempted to kill Katerina with a stake. Katerina used the owner of the cabin as a shield, which resulted in her death. Katerina then gave in to her instincts and drained the little old lady, completing her transition into a vampire. She then threw the body towards Rose and Trevor and fled into the night. Katerina returned to Bulgaria in the later 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 Amulets 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.
Katherine killed a man outside the French Court of Versaille. Nadia, who was in search of information on her mother's whereabouts, offered a large amount of gold to a man who witnessed Katherine commit this murder and informed him that Katherine had been on the run for 228 years by this point.

372 years had passed when Katerina arrived in Mystic Falls, Virginia in 1864, by which time she had taken the name Katherine Pierce, presumably to avoid detection by Klaus. At some point, she had become friends with Pearl and her daughter, Anna; another friend she made prior to this point was the witches Emily Bennett and Melinda Brown whose lives Katherine had saved, putting Emily and Melinda in her debt. Emily forged Katherine a special piece of jewelry with a lapis lazuli stone, which allowed her to walk in the sun without being burned and helped her keep her vampire identity a secret. She was taken in by one of the town's founders, Giuseppe Salvatore, having spun a story about being orphaned by a fire that killed her family in Atlanta to win her sympathy. Katherine met and fell in love with his younger son Stefan Salvatore, though she quickly began a physical relationship with Stefan's older brother, Damon, as well. Katherine created quite a few vampires while living in Mystic Falls, which inevitably alerted the Founding Families to their existence. Pearl warned Katherine that the town knew about the vampires after discovering an elixir that Honoria Fell had asked to be sold at the local apothecary which contained vervain. Pearl tried to convince her to leave, but Katherine refused, claiming she had a plan in motion. Her plan, it turned out, was to eventually turn Stefan and Damon into vampires, having seduced them both during her stay at the Salvatore household.

Realizing how quickly the Founder's Council would take action against the vampires, Katherine struck a deal with George Lockwood: she would give him the moonstone if he would help her fake her death in the inevitable vampire round-up. Eventually, Stefan unwittingly suggested to his father that he knew a vampire, and Giuseppe guessed Katherine's true identity. Giuseppe spiked Stefan's drink with vervain, and later that same night, Katherine bit him. She was incapacitated by the vervain in his bloodstream, and, hearing the commotion, Giuseppe burst in to take her away. Damon later went to rescue her, and Stefan, upset that he had hurt his brother and jeopardized Katherine's life, helped him in the effort. They were both killed by their own father, who was so ashamed that his sons had been seduced by a "demon" that he preferred to keep the story that they had died honorably in the war against the vampires.

Katherine and the other vampires were taken to Fell's Church to be destroyed, but George helped Katherine escape, as per their previous arrangement. She gave George the moonstone, but instead of leaving right away, she turned to see Stefan's body one last time while it was still lying in the road. She ran to Stefan, kissed him, and promised they would be together again someday. After transitioning into a vampire, Damon was told by Emily that Katherine was trapped in the tomb beneath the church, and as a result, the older Salvatore never stopped loving Katherine, as he impatiently awaited the day he would be able to rescue her from the tomb. In reality, Katherine was still lying low to evade Klaus, and she admitted to Stefan that she had seen him in the front row of a Bon Jovi concert in the 1980s to prove that she had continued to keep tabs on him over the decades.
Katherine was in Chicago at the same time as Stefan, but she only observed him from afar. After a police raid cleared out the speakeasy, Katherine spotted Rebekah's necklace on the ground. She moved to pick it up, but ran away before Stefan could see or notice her. She watched him for a few moments before slipping into the shadows.

Katherine employed the talents of the vampire Will, who owned the music club and bar, Billy'y in New York City. He also ran an identity theft ring that secured new identities for vampires. Damon, who was friends with Will and helped him by killing people to steal their ID cards, unwittingly helped Katherine in her mission to remain undetected, though he did not realize this fact until much later.

Anna told Damon that she had seen Katherine during this year in Chicago.

It was revealed that Katherine was watching Stefan and Lexi from afar at a Bon Jovi concert.

## Personality

* Witch
* Vampire
* Heretic

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.

After she had turned, she immediately fled the only vampires she knew and apparently learned to survive as one on her own. The large gap of time from her transition to her arrival in Mystic Falls is a mystery, but she likely befriended Pearl during this time. In 1864, she seduced both Damon and Stefan Salvatore, revealing to a compelled Stefan that she had big plans for the three of them to be together. Although she did develop genuine affection for both brothers, and even love for Stefan, she was also calculating and selfish, selling out the other vampires in town in order to fake her own death. Her actions both in 1492 and 1864 demonstrate an extremely well-developed sense of self-preservation, almost always at the expense of any human compassion or remorse.

In present day, Katherine remains very much the same in this respect. She returns to Mystic Falls with the goal of securing the moonstone as well as a vampire, a werewolf, and the second Petrova Doppelgänger, solely for the purpose of handing them over to Klaus in exchange for amnesty. In the process, she manipulates and seduces Mason Lockwood to have him do her bidding, orchestrates the activation of both Mason's and Tyler's werewolf gene, turns Caroline into a vampire, compels Jenna to stab herself, lures Jenna out of her house to be sacrificed in Klaus' ritual, and leaves behind her a trail of other casualties, all in the name of securing her freedom. However, she redeems herself to the Salvatores, if only slightly, first by delivering the antidote to Damon's werewolf bite and later by helping in the plan to kill Mikael.

Despite her ruthlessness, it is clear that Katherine has deep, genuine feelings for Stefan. Unable to reveal herself to him without ruining the usefulness of being dead, she still observed him from afar over the years, admitting as much to Stefan in the present day. In fact, Katherine is usually at her most honest about her true feelings when she believes she is unobserved, as when she kissed an unconscious Stefan before leaving Mystic Falls, and when she looked on at him in the 1920s speakeasy.

Her relationships with other characters also sometimes reveal a crack in the "psychotic bitch" facade. Although she claims to his face that she never loved him, Damon still holds some of her affection, and she has offered him genuine help more than once. With regard to her doppelgänger, although she was willing to trade Elena's life for her freedom from Klaus, she never demonstrated any real animosity toward her. In fact she freely admitted an admiration for her descendant's tenacity, a quality she values in herself. And despite fearing Elijah nearly as much as Klaus because of her escape centuries earlier, she has since become his ally, and even seems to genuinely care about and possibly love him.

Katherine's extremely heightened sense of self-preservation has helped her develop a knack for creating elaborate plans and deceptions. Even when she takes a risk, which must be well worth it, she proceeds with caution and a means of escape in place. Thus, despite whatever feelings she has for Stefan, Damon, and now Elijah, it cannot be certain whether she would save their lives over her own, though the evidence so far suggests Katherine could not help but choose her own survival above all else.

Moments before her death, she took advantage of Elena and possessed her because of her traveler heritage. In Elena's body, she tried to keep it a secret and one of the first things she did was break up with Damon. Her ultimate goal was to assimilate herself in Elena's life and discard Elena's soul/essence and try to have a romantic relationship with Stefan. Katherine first tricked Matt into thinking she was her, and got information from him to know more about Elena's life, compelling him to forget that she is in Elena's body. She pulls it off for a while, hiding from Elena's friends most of the time, but eventually everybody finds out, even though she had the help of her daughter, Nadia, who was also trying to keep it a secret. Stefan called her to the Salvatore house, and Katherine accepted her death in the end, but before she is finally gone revealed that she injected Elena with the ripper compound.

Throughout her centuries-long life, Katherine has always been tough, feisty, independent and smart. If a task needs doing, she'll find a way to accomplish it, usually through a combination of uncompromising will and skilled manipulation of people and circumstances. Her personal motto - "Better you die than I" - does well to encapsulate her instinct for self-preservation as well as the detached cruelty which many vampires choose to adopt. But in her private moments, there is yet a glimpse of the human girl who once said that life is too cruel to live without love.
Katherine still has the same personality but is a lot nicer to the people. She is willing to sacrifice her life for Alex most of all for giving her a second chance.

## Physical Appearance

Almost every character who has met any combination of the Petrova doppelgängers has remarked that Katherine looked identical to Amara, Tatia, Elena, or Alex. As such, Katherine was an extraordinarily beautiful and seductive young woman: she had a heart-shaped face with fine bone structure, a wealth of brown curly hair, and almond-shaped, deep brown eyes with thick dark lashes.

Katherine and Alex looked exactly identical, but once you know what to look for, you can distinguish the two easily, same goes with Elena. Katherine and Alex share the same shade color for their hair but Alex is seen either wearing it down the middle or a deep part on the right and has tight curly hair but can have loose curls, while Katherine parts her hair on the left with tight or loose curls. Katherine wore make-up a little bit differently than Alex; Katherine favored a dark smoky eye with thick winged eyeliner, and her choice in lipstick was a darker, sultry pink appearance, while Alex wears both dark smoky eye and bronze smoky eyes and a thick liner.

When deducing where Katherine bought most of her clothes, she was quoted as saying that she bought most of her shoes in Paris. The majority of her jeans are J-Brand, and almost the entirety of her tops, especially those worn in season 5, were from Bebe.

## Powers and Abilities

* Witch
* Vampire
* Vampire-Witch

Katherine before being turned into a vampire possessed all the standard powers and abilities of a mortal witch.

Katherine is able to subdue Klaus, an Original Hybrid and knock him out cold.
## Weaknesses

Katherine has the typical weaknesses of a non-Original vampire-witch hybrid.

## Relationships

### Nadia Petrova

*Main Article: Katherine and Nadia*

Nadia Petrova is the daughter of Katerina Petrova. Katherine gave birth to Nadia back in 1490 but Nadia was taken from her before she even got the chance to hold her. When Katherine returned to Bulgaria after being exiled to England and escaping Niklaus Mikaelson, she found that he killed her entire family and was devastated. She then began her search for her daughter who was 8 years old at the time, but to no avail, she was not able to find her. Over the years, Nadia was turned into a vampire, learning the story of her mother and searched for her for 500 years. When they meet again, Nadia introduces herself and begins to test Katherine, telling her she killed her mother in Paris. Katherine sees through this lie and Nadia reveals she did kill her mother, only in 1492 in England after she was exiled by her family. Katherine is shocked to learn that Nadia is her long lost daughter.

### Stefan Salvatore

*Main Article: Katherine and Stefan*

Katherine fell in love with Stefan when she met him in Mystic Falls in 1864. Although she was also seeing Damon, she had a clear preference for Stefan. She secretly watched over him while running from Klaus, and later admitted she had never once stopped caring about him. Katherine was unwilling to put her love for Stefan above her own survival and when she returned, they became enemies, as Katherine wanted to deliver Elena and Alex to Klaus in exchange for her freedom and Stefan was in a relationship with her. Nonetheless, Katherine persisted in her affections for Stefan despite his supposed hatred of her and declared she would wait for him forever if need be.

### Elijah Mikaelson

*Main Article: Elijah and Katherine*

The relationship between Katerina Petrova and Elijah Mikaelson, was once sweet and friendly up to the point where Katherine betrayed Elijah for her own freedom and that broke his relationship with his half-brother Klaus. When Elijah found Katherine in the vampire tomb, he compelled her to stay there until he said otherwise. Elijah later revealed that he made Katherine pay for betraying him, by running away from him as he was trying to save her life. She later witnessed his brother Klaus daggering Elijah. In American Gothic, it is revealed that Elijah and Katherine have been sleeping together and were in a relationship together, as they both have admitted to being in love with each other, although it is questionable whether Katherine's love for Elijah is genuine or just another ploy to get freedom. However soon when Katherine joins Alex to New Orleans her and Elijah started to fall once again towards one another.

### Alex Gilbert

*Main Article: Katherine and Alex*

The relationship between Katherine Pierce and Alex Gilbert started friendly when Katherine helped Alex with her magic abilities. Eventually when Alex learned that Katherine was a real bitch and was willing to sacrifice her to Klaus she started to loath her.

### Damon Salvatore

*Main Article: Katherine and Damon*

The relationship between Katherine Pierce and Damon Salvatore has been complicated since their meeting in 1864, when Katherine stayed in their estate and Damon was serving in the Confederate army. Damon fell deeply in love with Katherine, but unbeknownst to him, she'd also been seeing his brother Stefan, sparking the brothers' lifelong rivalry. Their relationship ended when the town began eradicating the vampires. She was then taken away, and Damon and Stefan were shot by their own father while in an attempt to save her, causing the latters' turning into vampires. Damon since then, has spent the following 150 years obsessed with freeing her from her tomb, only to find out that she was never in it in the first place. This ignited a newfound rivalry between the two. Despite them sharing a complicated alliance in modern times, Damon has shown to lose his patience with her rather quickly and this sparked an antagonistic relationship between the two.

## Name

* **Katherine** is a feminine first name of uncertain origin. It appears to come from the Greek *Αικατερινη* meaning "*each of the two*", or possibly from *καθαρος* (Katharos) meaning "*pure*". There are several famous bearers of this name, including Catherine de' Medici and Catherine the Great from Russia. The name is common in English. **Katerina** is of Bulgarian or Russian origin and means "pure".
* Petrov/Petroff (masculine) or **Petrova** (feminine) is one of the most common surnames in both Russia and Bulgaria. The surname is derived from the first name Pyotr (Пётр, Russian) or Petar (Петър, Bulgarian), both equivalent to the English name Peter. Petrov means "son of Peter" in Russian and Bulgarian.
* **Mikaelson** is of of Scandinavian origin and means "Son of Mikael".
	+ If Katherine was to truly follow Norse traditions, her married surname should technically be **Elijahson** (son of Elijah) as oppose to **Mikaelson** (son of Mikael). Evidence is Esther's married name being Mikaelson after she married Mikael.
