**Katherine Pierce**, born **Katerina Petrova** (**Bulgarian**: *Катерина Петрова*) is a vampire and a main character of the *An Epic Kind of Love* series. She is the second-known Petrova Doppelgänger of Amara. She was the main antagonist of Book 1 (indirectly through John Gilbert's and Isobel's actions, as both were working for her in order to kill off the tomb vampires).

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 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 fell in love with Elijah. 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 Stefan and Damon 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 doppelgänger who came after her, Elena Gilbert. 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 millenium ago.

Klaus stopped hunting Katherine down due to her relationship with Elijah, which ended their antagonistic relationship and began a tentative partnership between the two.

Katherine's notable ancestors include Amara, who was Silas' true love and 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 as the curse that bound Klaus' werewolf side. She is also the maternal ancestor of Isobel Flemming and that of Isobel's biological daughters, Elena and Adrianna Gilbert. She was once the romantic interest of Stefan and Damon Salvatore. She has also been the romantic interest of Elijah since the late 15th century, who she married.

Katherine is a member of the Petrova Family and the Mikaelson Family, due to her marriage to Elijah Mikaelson.

## Early History

* 1473-1490s
* 1720
* 1864
* 1920s

Katerina Petrova was born into a noble and wealthy 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 at first attracted to Klaus but soon grew to love Elijah. Eventually, she found out what they were and that they were planning on using her as a sacrifice to break the Hybrid Curse placed on Klaus. 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 Katherine 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 her 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, Pearl, Anna, and Harper daylight rings and her 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 witch Emily Bennett, whose life Katherine had saved, putting Emily 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 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 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.
## Throughout An Epic Kind of Love Series (Part 1)

* Book 1
* Book 2
* Book 3
* Book 4
* Book 5

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 the chaos settled, Katherine, having stolen some of Elena Gilbert's clothes, goes to the Gilbert house, where she posed as Elena in the presence of Jenna, Adrianna, and Damon. Jenna, not knowing of the existence of vampires, invited her in believing that she was Elena. Later in the night, she interrupted Adrianna and Damon's kiss. Katherine later startles John in the kitchen, still pretending to be Elena. She notices the Gilbert ring he is wearing and, using a butcher's knife, viciously chops his fingers off, then stabs him. Adrianna hears his screaming and hurries down the stairs to see John on the ground, clutching his hand. As she is helping him, Elena arrives and John tries to warn them that Katherine was behind them.

"*I was you before you even existed!*"
—Katherine to Elena

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 hold 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 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' wrath upon them all.

"*We manipulate, we thirst for power, we control, we punish, but our actions are driven by one singular place deep inside. We're alone, and we hate it.*"
—Katherine about Klaus and herself

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 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, 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, turned Caroline and Adrianna into vampires, compels Jenna to stab herself, lures Jenna out of her house to be sacrificed in Klaus' ritual, and leaves behind her a trail of casualties, all in the name of securing her freedom. However, she redeems herself to the Salvatores and Adrianna, first by delivering the antidote to Damon's werewolf bite, delivering Adrianna's note to Damon, 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 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 doppelgängers, Katherine likes Adrianna more than Elena, and even forms a genuine and very close friendship with the former. Despite fearing Elijah nearly as much as Klaus because of her escape centuries earlier, she still genuinely cares for and loves 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.

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, especially those with her husband, there is a glimpse of the human girl who once said that life is too cruel to live without love.
## Physical Appearance

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

Katherine, Elena, and Adrianna are remarked to be identical, but once you know what to look for, you can distinguish the three easily, though it's a little harder to distinguish Adrianna and Katherine than Elena and Katherine. Katherine's hair naturally has loose or tight curls and she usually parts her hair on the left. She favors a dark smoky eye with thick winged eyeliner, and her choice of lipstick is a darker, sultry pink appearance.

Katherine is often seen wearing either leggings or dark super-skinny jeans to show off her fit figure, along with either blue, purple, or black tank tops. She almost always wears a black leather jacket over her clothes, either cropped, full length, buttoned, or with a zipper. She always wears black high heeled booties, open-toed pumps, or tall, black "500 dollar boots." Katherine also wears a lot of jewelry, including her lapis lazuli daylight bracelet, chain bracelets in either silver or gold, and a watch.

Whenever Katherine pretended to be Elena, she parted her hair in a deep right parting, and styled the front of her hair in loose curls and waves, leaving the back of her hair straight or slightly wavy. However, Katherine would choose clothes that Elena wouldn't wear, and the main distinguishing feature was usually her thick abundance of hair.

## Powers and Abilities

* Witch/Human
* Vampire

Katherine possessed all the standard powers and abilities of a mortal witch. However, she never had a chance to tap into that magic before she was turned into a vampire.

"*This is Katherine we're talking about. She's going to see a sneak attack coming from a mile away.*"
—Caroline about Katherine

Katherine possesses all the standard powers and abilities of a non-Original vampire. She is a very experienced fighter, able to hold her own against both Stefan and Damon in battle. Being 538 years old made Katherine one of the most powerful vampires to appear in the series. Katherine is known and feared by almost everyone.
## Weaknesses

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

## Minions

* Emily Bennett - She was Katherine's handmaiden in 1864 as well as a powerful witch. Katherine betrayed her when she told the people in the town that Emily was a witch.

* Henry Wattles - He was a vampire who helped Katherine to investigate the werewolf attacks within the town of Mystic Falls back in 1864. Henry was staked and killed by Alaric Saltzman.

* George Lockwood - George was a werewolf and the co-conspirator in Katherine's fake death. She and George made a deal in which George helped her escape, telling no one of it, in exchange for her giving George the moonstone.

* Will - He had a business to get vampires fake identities, but since he was unable to walk in sunlight and kept busy with his work at his bar, he made a deal with Damon where Damon could feed on his customers in exchange for stealing IDs for him. He was said to have provided many, if not all of Katherine's identities over the last few decades, many of which were during the 1970s.

* Mason Lockwood - Mason was a werewolf and a romantic partner of Katherine's in the 21st century, whom she manipulated in order to obtain the moonstone. Mason was killed by Damon.

* Jimmy - He was a friend of Mason Lockwood. Katherine used compulsion on Jimmy and got him to attack Mason after accusing him of sleeping with his girlfriend, Marla. Mason accidentally killed him, which triggered his werewolf curse.

* Isobel Flemming - Isobel is Elena and Adrianna's biological mother and Katherine's descendant. She helped Katherine in her plan to destroy the tomb vampires and seek information about the Originals. Katherine also helped her obtain a lapis lazuli necklace to allow her to walk in daylight. Isobel later betrayed Katherine.

* John Gilbert - Isobel, acting as proxy for Katherine, asked John to get a device, enchanted by Emily Bennett, that was taken from Johnathan Gilbert in 1864. John failed to get the device, so Isobel managed to get it herself by kidnapping Jeremy in order to trade him for it. She then gave it to John, who used it to destroy the vampires who had been freed from the tomb. Katherine was the one to instigate the plan to kill the tomb vampires.

* Jenna Sommers - Katherine used compulsion on Jenna to spy on Elena and Stefan. After Katherine learned of Mason Lockwood's death, she ordered Jenna to commit suicide by stabbing herself, though Jenna thankfully survived her injuries.

* Caroline Forbes - Katherine turned Caroline into a vampire by smothering her with a pillow in her hospital room after Damon had healed her with his blood. Afterward, she continued to threaten and manipulate her to do her bidding. She ordered Caroline to keep Elena away from Stefan and to occupy her for the day so that Katherine could spend time with him.

* Matt Donovan - After learning of Mason's death, Katherine compelled Matt to provoke Tyler Lockwood into killing him in order to trigger Tyler's werewolf curse. She then planned to hand over Elena, Tyler, Caroline or Adrianna, and Bonnie to Klaus, along with the moonstone, so that he would have all the components needed to break the Hybrid Curse. Her hope was that she could leverage these items for her freedom, but her plan ultimately backfired.

* Sarah - Katherine compelled her to attack Tyler if Matt failed, and when Caroline broke up Matt and Tyler's fight, Sarah attacked Tyler and he accidentally killed her by shoving her away from him, resulting in her breaking her neck when she fell on the corner of a table. Sarah's death triggered Tyler's werewolf curse.

## Relationships

### Nadia Petrova

"*I went back. For you.*"
—Katherine to Nadia

*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 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 that she did kill her mother, only in 1492 in England after she was exiled by her family. Katherine initially pushed her away but ultimately chose to say goodbye to Nadia as Nadia dies of Tyler's werewolf bite.

### Stefan Salvatore

"*You hate me, huh? Thats sounds like the beginning of a love story, Stefan, not the end of one.*"
—Katherine to Stefan

*Main Article: Stefan and Katherine*

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 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. They eventually become closer after she willingly helped him with some plans against Klaus.

### Elijah Mikaelson

"*I love you, Elijah. I always have and I always will*"
—Katherine to Elijah

*Main Article: Elijah and Katherine*

Elijah Mikaelson is Katherine's best friend and husband. Katherine first met Elijah in 1492 while she was still human. Unbeknownst to her, Elijah was at first attracted to her because she looked like a loved one from his past. Though Katherine had an initial attraction to Klaus, her feelings for Elijah grew. Before she could officially act on her feelings, Katherine found out that they were vampires and planned to use her to break a curse. Katherine ran away from them and became a vampire herself. She stayed away from Elijah and the rest of his family for the next 500 years. They are reunited after over 5 centuries, when Elijah compelled her to remain in the tomb beneath Fell's Church until he said otherwise. Elijah later reveals that he had found a way to save Katherine's life but she had ran away from him before he could reveal it to her. Some time later, Elijah and Katherine began a romantic relationship, as they both have admitted to still being in love with each other. They have remained together ever since but have spent a lot of time separated, due to the Mikaelson's problems in New Orleans and Katherine traveling. This was Elijah's way of protecting Katherine from his problems and enemies in New Orleans. Katherine and Elijah are currently married.

### Adrianna Gilbert

"*I like you because you're funny. And you're better than your dull as a dishwater twin sister.*"
—Katherine to Adrianna

*Main Article: Adrianna and Katherine*

Adrianna is one of Katherine's best friends. They unofficially met when Katherine pretended to be Elena at the end of Book 1. Adrianna officially meets her at the beginning of Book 2 when Katherine fed her blood and killed her. Katherine continues to antagonize her and her friends, mostly focusing on Elena. Adrianna thought it was jealousy over the fact that Elena had Stefan and Katherine wanted him. Adrianna was a part of the plan to kill Katherine at the Masquerade Ball, which was almost successful until they found out that Elena was linked to Katherine. It was then decided that it would be better to lock Katherine in the tomb under Fell's Church. After finding out about the Original family, Adrianna goes to Katherine for information and Katherine's plan for them. When Adrianna asks why Katherine turned her, Katherine told Adrianna that she liked her and that Adrianna reminded her of herself. When Katherine escapes the tomb, she stays in Mystic Falls to help them against Klaus. However, Katherine ends up taken by Klaus and is held for days. When Adrianna decides to leave town with Klaus for the summer in order to save Damon's life, she gives Katherine a message to give Damon, which she does deliver. Throughout the summer, Katherine watched Adrianna from afar. At one point she even sets up a call between Adrianna and Damon. By the end of Book 3 Adrianna has a more positive relationship with Katherine, even referring to her as her friend. This fragile relationship is later broken due to Katherine's role in Jeremy's death in Book 4. After trying, and failing, to kill Katherine, Adrianna hesitantly moved on. The two are separated when Katherine leaves Mystic Falls at the end of Book 4. They are later reunited. Adrianna was the maid of honor at Katherine's wedding to Elijah and Katherine was a bridesmaid at Adrianna's to Damon.

### Damon Salvatore

"*Damon, I taught you how to love but [Adrianna] showed you what it felt like to be* in *love and have that love returned*"
—Katherine to Damon

*Main Article: Damon and Katherine*

The relationship between Katherine Pierce and Damon Salvatore has been complicated since they 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 letters' 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.

## Trivia

* Katherine's birthday is June 5 and her astrological sign is Gemini.
* Most people use the Anglo version *Katherine* for her name. However Klaus, Elijah, Rose, and Trevor refer to her by her original name *Katerina*.
