Katerina Petrova (Bulgarian: Катерина Петрова; English: Katherine Pierce), is a vampire who first appears as Katherine Pierce in recurring flashbacks to 1864, which feature her romantic entanglements with Damon and Stefan Salvatore. She managed to turn them both into vampires, but she was concurrently captured by the townspeople of Mystic Falls to be destroyed.

Behind her sweet-natured facade, a much more calculating side of Katherine is revealed through flashbacks in which she escaped certain death with the help of George Lockwood (and at the expense of all the other vampires in town) in 1864. After 145 years, Katherine returns to Mystic Falls, toying with the Salvatore's again but clearly with a hidden agenda. Katherine earns no love after she turns Caroline Forbes into a vampire and uses a werewolf, Mason Lockwood, to retrieve a mysterious moonstone. Eventually she is exposed as a doppelgänger who has spent her immortal life fleeing from an Original named Klaus.

Katherine promises John Gilbert that she will help protect her descendant Elena Gilbert, even though the younger doppelgänger is her competition for the Salvatore's affections. She is initially portrayed as the main antagonist, but upon the arrival of Elijah, another Original vampire, Katherine is clearly terrified by the prospect of finally being caught by Klaus. Once she escapes at the end of the second season, she flees Mystic Falls almost immediately.

Katerina Petrova is a member of the Petrova Family. {| class="toc" id="toc"

HistoryEdit
 Katerina asking to see her daughter.Added by JenthewarriorKaterina Petrova (Cyrillic Катерина Петрова) was born into a wealthy Bulgarian family on 22 June 1475. In 1490, when she was about 15 or 16 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. Katerina was devastated by this and was banished to England. After being banished to England, she quickly adjusted by 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 a cottage, Katerina met a vampire named Rose.  Katherine in 1492Added by Szod14When 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. 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 she woke up in transition, Trevor asked why she did it and claimed he would've 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 explains to Trevor that Katerina used him to escape and, knowing Klaus would see 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 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 in this time period weeping over her mother's dead body.

1864Edit
 Katherine and Stefan's first meeting in 1864.Added by Xo12Hundreds of years had passed when in 1864 Katerina arrived in Mystic Falls, Virginia, 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, and she saved the life of the witch Emily Bennett, putting Emily in her debt. Emily forged her a special piece of jewelry with the stone Lapis Lazuli which allowed her to walk in the sun without being burned. 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. Katherine met and fell in love with his 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 of their existence. Alerting Katherine to an elixir containing Vervain that Honoria Fell had asked to be sold at the apothecary, Pearl tried to convince her to leave, but Katherine refused, claiming she had a plan in motion. Her plan, it turned out, was to turn Stefan and Damon into vampires, having seduced them both during her stay at the Salvatore household.  Katherine In 1864Added by LittlemisskatherineRealizing 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. 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 trying to save her, shot by their own father, Giuseppe, who was ashamed his sons had succumbed to the wiles of a demon.  Katherine leaving town and promises Stefan that they will be together again.Added by VampgirlrocksKatherine and the other vampires were taken to Fell's Church to be destroyed, but George helped Katherine escape. She gave George the moonstone, but instead of leaving right away, she turned to see Damon and Stefan's bodies 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 awaited the day he would be able to rescue her. In reality, Katherine was still lying low to evade Klaus, and she kept a close eye on the younger Salvatore brother, pointing out that she had seen him in the front row of a concert in the 1980s to prove that she'd always been watching over him.

1920sEdit
 Katherine in the 20's.Added by Team Damon x3In the 1920s, 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 stabs John Gilbert.Added by Neil93When 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. In Founder's Day after the chaos has settled, Katherine, having stolen some of Elena Gilbert's clothes, goes to the Gilbert house, where she poses as Elena in the presence of Damon. The two kiss, only to be interrupted by Elena's aunt, Jenna Sommers. Unaware of the presence of vampires or the existence of Katherine, Jenna invites her into the house. Katherine startles John Gilbert in the kitchen, still pretending to be Elena. She notices the magic ring he is wearing and, using a butcher's knife, viciously chops his fingers off, then stabs him. Elena arrives and comes to John's aid while Katherine hovers behind her.

Seeing John Gilbert seriously injured, Elena calls for help and is terrified by Katherine's super-speed around the house before leaving. Upon her return, Damon and Stefan are left reeling after she's caused so much damage in so little time. At the mayor's wake at the Lockwood mansion, she engages in a small power play with Bonnie, claiming that it never ends well for Bennett witches. Bonnie attempts her usual attack against vampires, but Katherine, a much older vampire than Bonnie is used to encountering, seems to have a certain amount of resistance to such spells.  Katherine watches ElenaAdded by Alaric SaltzmanKatherine claims to Stefan that she returned for him, and the two engage in light banter, Katherine playfully and Stefan suspiciously. Their conversation effectively ends when Stefan tells Katherine he hates her and in retaliation she skewers him with a metal rod. Later, Damon demand the truth after he and Katherine make out, and she confesses that she never loved him and that "it was always Stefan" that she loved.

Later, she visits Caroline Forbes in the hospital and tells her to give the Salvatores a message: "Game on." Then she smothers Caroline with a pillow, killing her with Damon's blood in her system. Katherine next to CarolineAdded by HoneiVladmirA few days later, Katherine appears in Caroline's bedroom and tells her not to be frightened, and that they were going to have so much fun together.After blackmailing Caroline into distracting Elena, Katherine sets her sights on Stefan for the day. She gets an early start by manipulating his dreams, bringing him back to when he had escorted her to the Founder's Ball in 1864. In the dream, he notices that Damon has found someone to entertain himself with - Elena. Katherine then takes the dream to present day, where Elena and Damon are getting cozy at the Mystic Grill. Stefan wakes suddenly to find Elena asleep in his arms, but he quickly realizes it is actually Katherine.

Later, after he has locked Katherine up in the cellar and threatened her with vervain unless she tells the truth about her return, Stefan interrogates her and she reveals her deal in 1864 with George Lockwood, a werewolf. In exchange for the rare moonstone, Lockwood saved her from imprisonment in the tomb. Stefan points out that she betrayed all the other vampires, including her friend Pearl, just to fake her death, and Katherine seems to have no regrets about her past actions. She insists that she never compelled Stefan to love her, that his love for her was real, and she only compelled him not to fear her. After she escapes the interrogation, she finally meets her doppelgänger, Elena, face to face. In a final flashback to 1864, Katherine is ready to leave Mystic Falls, but falls back to kiss an unconscious Stefan one last time, promising they would be together again one day. <img alt="Katherine, 2x07" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="102" class="thumbimage lzy lzyPlcHld" data-src="http://images4.wikia.nocookie.net/__cb20130127232607/vampirediaries/images/thumb/7/7e/Katherine%2C_2x07.jpg/180px-Katherine%2C_2x07.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katherine, 2x07" src="http://images4.wikia.nocookie.net/__cb20130127232607/vampirediaries/images/thumb/7/7e/Katherine%2C_2x07.jpg/180px-Katherine%2C_2x07.jpg" width="180" height="102" class="thumbimage" />The Salvatores try to kill Katherine.Added by Alange9It is soon revealed that Katherine had set up Mason Lockwood's first kill in order to trigger his werewolf gene. She continues to manipulate him by seducing him and persuading him to find the moonstone from the Lockwood mansion. After Mason is killed, Katherine compels Jenna to stab herself as revenge on the Salvatore camp, and also compels Matt to pick a fight with Tyler and not stop until Tyler kills him. Katherine decides to retrieve the moonstone herself with the help of Lucy, a witch. She dances with Stefan and briefly tries for a diplomatic surrender, but when he refuses to give up the stone, she kills Aimee Bradley in the middle of the dance floor. Later, Caroline successfully lures Katherine into a room upstairs that Bonnie had put a spell on, preventing vampires from leaving it. Stuck in the room with Damon and Stefan, Katherine goads the brothers until they attack her. <img alt="Damonsealedkat" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="174" height="98" class="thumbimage lzy lzyPlcHld" data-src="http://images2.wikia.nocookie.net/__cb20101102185212/vampirediaries/images/thumb/d/d9/Damonsealedkat.jpg/174px-Damonsealedkat.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Damonsealedkat" src="http://images2.wikia.nocookie.net/__cb20101102185212/vampirediaries/images/thumb/d/d9/Damonsealedkat.jpg/174px-Damonsealedkat.jpg" width="174" height="98" class="thumbimage" />Damon imprisons Katherine.Added by Alaric SaltzmanUnfortunately, Lucy had cast a spell over Katherine and Elena so that whatever happened to Katherine would also happen to Elena. After learning of Bonnie's involvement, however, Lucy turns the tables on Katherine; after her debt to Katherine has been paid by getting her the moonstone, Lucy incapacitates her. Katherine awakes imprisoned in the tomb, where Damon says she should have been for a long time. As Damon closes the door of the tomb, Katherine screams that Elena is in danger and needs to be protected. <img alt="Katerina015" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="101" class="thumbimage lzy lzyPlcHld" data-src="http://images1.wikia.nocookie.net/__cb20110215054725/vampirediaries/images/thumb/e/e4/Katerina015.png/180px-Katerina015.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katerina015" src="http://images1.wikia.nocookie.net/__cb20110215054725/vampirediaries/images/thumb/e/e4/Katerina015.png/180px-Katerina015.png" width="180" height="101" class="thumbimage" />A severely weakened Katherine greets Elena.Added by ElementalstudiosAfter learning from Rose about the existence of the Originals, Elena visits Katherine to ask her about her past. Katherine complies in exchange for incremental amounts of blood; he time in the tomb without sustenance has weakened her. Through flashbacks, Katherine reveals that she had borne a child before she was turned, and that she was the first Petrova doppelgänger. She explains that, as such, Klaus wanted to sacrifice her as part of a ritual to break a curse. Katherine recounts how she foiled Klaus' plan by tricking Rose into turning her, thus rendering her useless for the sacrifice. Now that another doppelgänger had appeared, the moment Klaus discovered Elena's existence he would find her for the sacrifice and attempt the ritual again. <img alt="Katerina040" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="174" height="98" class="thumbimage lzy lzyPlcHld" data-src="http://images2.wikia.nocookie.net/__cb20110215055323/vampirediaries/images/thumb/3/37/Katerina040.png/174px-Katerina040.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katerina040" src="http://images2.wikia.nocookie.net/__cb20110215055323/vampirediaries/images/thumb/3/37/Katerina040.png/174px-Katerina040.png" width="174" height="98" class="thumbimage" />Katherine tearing up while looking at portraits of her parentsAdded by ElementalstudiosWhen Stefan finally arrives searching for Elena, Katherine warns them that Klaus would not hesitate to kill all of the people Elena loves, just like Klaus had done to her. Stefan accuses her of tricking Elena, in a desperate attempt to get herself out of the tomb, but Katherine insists that the tomb is the safest place to be, as no vampire would want to enter for fear of being trapped. Later, alone once more, Katherine peruses the Petrova family history that Elena had brought, tearing up over drawings of her parents.

In an attempt to get the moonstone from Katherine, Bonnie performs a spell that involves burning Stefan's picture of Katherine from 1864 and throwing the ashes on her, rendering her unconscious for a minute or two. Jeremy, in a valiant effort to spare Bonnie from overexerting her powers, ventures into the tomb alone and asks Katherine for the moonstone. Naturally she refuses, so he shoots a stake into her chest and, while she's distracted, throws the ashes into her face and incapacitates her. While she is unconscious, he enters the tomb, searches for and finds the moonstone, and tries to leave but Katherine revives and attacks him. When Stefan and Bonnie arrive, Katherine holds Jeremy hostage and demands that Bonnie open the tomb so that she can escape. When Bonnie fails, Katherine bites Jeremy but Stefan reacts by entering the tomb and throwing Jeremy out of it, now imprisoning himself along with Katherine. <img alt="216VampireDiaries0414" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="184" height="104" class="thumbimage lzy lzyPlcHld" data-src="http://images4.wikia.nocookie.net/__cb20110505151430/vampirediaries/images/thumb/0/08/216VampireDiaries0414.jpg/184px-216VampireDiaries0414.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="216VampireDiaries0414" src="http://images4.wikia.nocookie.net/__cb20110505151430/vampirediaries/images/thumb/0/08/216VampireDiaries0414.jpg/184px-216VampireDiaries0414.jpg" width="184" height="104" class="thumbimage" />Damon and KatherineAdded by Aleu el12345Katherine is very pleased with herself for trapping Stefan with her. She enjoys planting dreams in his head while he sleeps, though later she does offer the useful advice of seeking out Isobel for information about Klaus. After Elena strikes a deal with Elijah, the warlock Jonas breaks the spell of the tomb, allowing vampires to leave it. Elijah allows Stefan to leave, but compels Katherine to stay inside.

When Damon visits Katherine in the tomb fishing for confirmation about how to kill an Original, she begs Damon not to kill Elijah, because then she would be stuck in the tomb forever. Later this is revealed to be a lie: rather, Katherine knew that killing the Original that had compelled her would actually release her from the compulsion. After they've staked Elijah, Damon finds Katherine in his shower, cheekily asking for a robe to borrow. She further surprises Damon by reaffirming her pledge to help him protect Elena. Katherine subsequently takes up residence with the Salvatore brothers, much to the displeasure of Elena.

Katherine repeatedly states that she will help them to deal with Klaus, and engages in research with the brothers. She is staked and nearly killed by Luka Martin when he infiltrates the mansion via astral projection in an attempt to release Elijah, but is rescued by Damon, who unwittingly burns Luka to death. When his father strikes out in a rage against Elena, Katherine tricks him into believing that she is Elena and kills him. Later, she flirts with Damon in bed, despite admitting to him that she knew the dagger would kill the vampire who used it, and, having to make a choice between Damon and Stefan in a deal with John and Isobel, she chose Stefan once again. Needless to say, Damon does not play along and asks Katherine to find another room to sleep in.

Despite insisting to Stefan and Damon that she's on their side when it comes to killing Klaus, Katherine reunites with Isobel, formulating a contingency plan in case things don't go well for the Salvatores. She helps Isobel kidnap Elena, but soon Isobel double-crosses her and the warlock Maddox incapacitates her, later delivering her to Klaus.

In The Last Dance, Klaus/Alaric compels her to tell him everything she knows, even coaxing out of her information she isn't sure about. He denies her request that he just kill her; he considers death to be a "kindness" after searching for her for over 500 years, and promises to draw out his punishment for at least half as long. After their conversation, Klaus/Alaric hands her a pocket knife and compels her to stab herself repeatedly until he returns. In Klaus, Katherine asks Klaus/Alaric why he would undo the curse in Mystic Falls knowing that a lot people will try to stop him. <img alt="219VampireDiaries1291" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="184" height="104" class="thumbimage lzy lzyPlcHld" data-src="http://images4.wikia.nocookie.net/__cb20110505151822/vampirediaries/images/thumb/9/95/219VampireDiaries1291.jpg/184px-219VampireDiaries1291.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="219VampireDiaries1291" src="http://images4.wikia.nocookie.net/__cb20110505151822/vampirediaries/images/thumb/9/95/219VampireDiaries1291.jpg/184px-219VampireDiaries1291.jpg" width="184" height="104" class="thumbimage" />Katherine dancingAdded by Aleu el12345Klaus/Alaric reveals to her that he must perform the ritual at the doppelgängers birthplace. Katherine remarks that she didn’t know that was a requirement, to which Klaus/Alaric responds with the cruel reminder that, though she had fled before she could learn these details, Klaus did just fine finding her birthplace - and slaughtering her family. As Klaus/Alaric is leaving, he tells her she can't leave until he tells her to. Later, Damon and Andie Star go to Alaric’s apartment to discover Katherine is alive. Damon tells Katherine he has vervain, which won’t undo Klaus/Alaric’s compulsion but will prevent further compulsion. Before he gives it to her, he demands to know why she double-crossed them with Isobel. She replies that she didn't think the others could stand a chance against Klaus and she was looking out for herself. Damon gives her the vervain and tells her she owes him - and he will collect. Later that night Katherine is drinking and dancing around the apartment until she hears Klaus/Alaric returning. He tells her Alaric's body is no longer useful. Irritated when Katherine tries to ply him with alcohol, Klaus/Alaric snatches the bottle away from her, throws it against the wall and compels her to sit down and shut up. Having taken the vervain, Katherine only pretends to submit to his compulsion. When Maddox returns with Greta and Klaus's casket, they perform a spell to return Klaus to his true body. They open the casket and Katherine watches in horror as the real Klaus walks out.<img alt="220VampireDiaries1848" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="178" height="100" class="thumbimage lzy lzyPlcHld" data-src="http://images3.wikia.nocookie.net/__cb20110505152515/vampirediaries/images/thumb/0/0e/220VampireDiaries1848.jpg/178px-220VampireDiaries1848.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="220VampireDiaries1848" src="http://images3.wikia.nocookie.net/__cb20110505152515/vampirediaries/images/thumb/0/0e/220VampireDiaries1848.jpg/178px-220VampireDiaries1848.jpg" width="178" height="100" class="thumbimage" />Katherine shocked after Damon says he's been bitten by a werewolfAdded by Aleu el12345In The Last Day, Damon goes to Alaric's apartment to collect his debt for giving her vervain. He asks Katherine where Klaus is keeping the werewolf. Katherine is reluctant to help out but reveals that Klaus has captured Caroline and Tyler. She is shocked to learn that Elena has vampire blood in her system and Damon warns her that this means she would have to compete with Elena for Stefan's love forever. Katherine reveals that Caroline and Tyler are being held in the tomb.

Klaus returns to Alaric's apartment and is immediately suspicious of Katherine. He compels her to tell him what she has been doing but, as she is taking vervain, she is able to lie. Still suspicious, he compels her to remove her daylight bracelet, walk to the window and stand in the sunlight. Katherine has to do it to keep up the ruse and screams in pain until Klaus relents, satisfied. Later that night, after Klaus returns to the apartment and tells Katherine that Elena is with Greta, Damon appears and tells Klaus that he rescued the werewolf and vampire and killed Maddox, thereby foiling his plan. Klaus has Katherine leave the room, then informs Damon of his backup plans. Katherine revives Damon with a blood bag (Klaus had knocked him out off-screen) and tells him that Klaus has gone to begin the ritual. She admits that she had to do something so Klaus wouldn't realize she was on vervain, and reveals that Klaus made her make a call as Elena to lure someone out, explaining that he needed another vampire. Damon asks why Klaus didn't use him as the vampire in the sacrifice. Apparently Klaus had said that Damon was as good as dead. She points out the ugly wound on his arm and asks what it is. He replies, "It's a werewolf bite."

In The Sun Also Rises, Damon shows Katherine his werewolf bite but decides to leave. She is hurt that after 145 years he is leaving without saying goodbye and tells him not to depart on bad terms. She insists that she didn't have a choice and had to lure Jenna for Klaus, adding that she chose her life over Jenna's. Damon observes that Katherine will survive all of this without a scratch. Katherine points out that she doesn't let love get in the way and Damon tells her to enjoy an eternity alone. He leaves to offer himself to Klaus, but Katherine insists that Klaus won't accept him as his blood is impure.

In As I Lay Dying, Damon has a flashback and remembers speaking to Katherine in the 1860s. In it, she asks if he will miss her while he is off fighting and he says he will, but points out that she will still have Stefan. Katherine asks if it is so wrong for her to want them both. However, Damon hallucinates that Elena has joined them. Elena tells him that Katherine was just toying with him and he could have walked away - he had a choice. Flashback-Katherine bids him to return quickly. <img alt="2X20KatherineBite" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="101" class="thumbimage lzy lzyPlcHld" data-src="http://images3.wikia.nocookie.net/__cb20110517070707/vampirediaries/images/thumb/f/fb/2X20KatherineBite.png/180px-2X20KatherineBite.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="2X20KatherineBite" src="http://images3.wikia.nocookie.net/__cb20110517070707/vampirediaries/images/thumb/f/fb/2X20KatherineBite.png/180px-2X20KatherineBite.png" width="180" height="101" class="thumbimage" />Katherine after being bitten by KlausAdded by ElementalstudiosStefan shows up at Alaric's apartment looking for Klaus and finds Katherine there, wondering why Klaus's compulsion hasn't worn off. He admits that they failed to kill him just before Klaus returns. She watches as Stefan tries to bargain with Klaus for the cure to a werewolf bite. Klaus calls Katherine over and bites her; she starts to panic, but Klaus immediately feeds her his blood, and the bite heals, revealing that Klaus's blood is the cure. Meanwhile, Damon suffers more hallucinations of Katherine, mixing the present with the past, thinking he is chasing her through some woods. He remembers begging Katherine to feed him her blood so they could be together forever. Back in the apartment, Klaus calls Katherine over and compels her to take his blood to Damon and to come right back. She leaves immediately, but Stefan, knowing that Katherine has been ingesting vervain, worries that she will never deliver the cure to Damon.<img alt="1544" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="101" class="thumbimage lzy lzyPlcHld" data-src="http://images3.wikia.nocookie.net/__cb20111028040060/vampirediaries/images/thumb/a/a0/1544.jpg/180px-1544.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="1544" src="http://images3.wikia.nocookie.net/__cb20111028040060/vampirediaries/images/thumb/a/a0/1544.jpg/180px-1544.jpg" width="180" height="101" class="thumbimage" />Katherine and ElenaAdded by Szod14However, Katherine does follow through and appears at the eleventh hour, interrupting Elena's would-be final moments with Damon. She admits that she decided to deliver it because she owed Damon. Elena asks about Stefan, and Katherine informs them that Stefan has surrendered himself to Klaus in exchange for the cure. Before she leaves, and after taunting Elena about working two Salvatores at once, she adds that it's OK to love them both - she did, after all.

She declines to tell Damon where she is, but is later seen exiting a phone booth in Chicago. In Disturbing Behavior, she is still in Chicago and catches Stefan's attention outside of a boutique where Rebekah is trying on clothes. She fishes for information about Rebekah's necklace, which Klaus is looking for and which Stefan gave to Elena. She wants to know Stefan's plans, but he refuses to share them. Katherine warns him about plotting against Klaus, as well as dealing with Rebekah. She later saves him from Gloria's torture by stabbing the witch in the neck, and wants in on his plans if they involve taking down Klaus, but he turns her down again. <img alt="Katherine with Elena's necklace" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="190" height="97" class="thumbimage lzy lzyPlcHld" data-src="http://images4.wikia.nocookie.net/__cb20111009095417/vampirediaries/images/thumb/3/32/Katherine_with_Elena%27s_necklace.png/190px-Katherine_with_Elena%27s_necklace.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katherine with Elena's necklace" src="http://images4.wikia.nocookie.net/__cb20111009095417/vampirediaries/images/thumb/3/32/Katherine_with_Elena%27s_necklace.png/190px-Katherine_with_Elena%27s_necklace.png" width="190" height="97" class="thumbimage" />Katherine with the Original Witch's Talisman NecklaceAdded by ChaniqueTowards the end of the episode, Katherine fools Bonnie into thinking she's Elena, and manages to steal Esther's Talisman. She shows up at the Boarding House with the necklace, proposing to Damon that they team up and get away from Mystic Falls to go on a little "road trip".

In The Reckoning, after they stop the car, Katherine reveals to Damon that she has kidnapped Jeremy. She needs Jeremy because he is able to communicate with ghosts, and he has a connection with Anna, one of the only people who knew anything about Mikael, a vampire who hunts vampires. Anna says Mikael is the only one who can kill Klaus for good, and he was entombed by a witch in the 1990s. Anna reluctantly gives them information about him, warning them that Mikael will kill all of them if awakened. <img alt="Tvd-recap-smells-like-teen-spirit-49" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="190" height="120" class="thumbimage lzy lzyPlcHld" data-src="http://images2.wikia.nocookie.net/__cb20120104004224/vampirediaries/images/thumb/4/46/Tvd-recap-smells-like-teen-spirit-49.png/190px-Tvd-recap-smells-like-teen-spirit-49.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Tvd-recap-smells-like-teen-spirit-49" src="http://images2.wikia.nocookie.net/__cb20120104004224/vampirediaries/images/thumb/4/46/Tvd-recap-smells-like-teen-spirit-49.png/190px-Tvd-recap-smells-like-teen-spirit-49.png" width="190" height="120" class="thumbimage" />Katherine offers Mikael a mouseAdded by Katherine-KatKatherine ignores her warning, and is able to locate his tomb with Jeremy's help. Katherine spends two days trying, unsuccessfully, to get Mikael to feed, and finally brings him a human and drips fresh blood into his mouth. Mikael opens his eyes, and, horrified, orders her to stop feeding him the blood. As he continues to lay in his coffin, still very weak, she begins to doubt his formidable reputation. She asks him whether he can kill Klaus or not, and Mikael answers affirmatively. He asks Katherine to remove the chains restraining him; after she does, he reveals that he does not feed on living things, and proceeds to attack and feed on her. <img alt="Normal NDNET 1099" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="101" class="thumbimage lzy lzyPlcHld" data-src="http://images4.wikia.nocookie.net/__cb20111112192553/vampirediaries/images/thumb/8/85/Normal_NDNET_1099.jpg/180px-Normal_NDNET_1099.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Normal NDNET 1099" src="http://images4.wikia.nocookie.net/__cb20111112192553/vampirediaries/images/thumb/8/85/Normal_NDNET_1099.jpg/180px-Normal_NDNET_1099.jpg" width="180" height="101" class="thumbimage" />Katherine as Elena getting stabbed by Mikael.Added by Silver09In Homecoming, Damon enlists Katherine in a plan to kill Klaus. She pretends to be Elena so that Elena won't be in danger when everything goes down. However, during the party, Klaus, thinking that she is Elena, reveals that in the event that Klaus is killed, the other Hybrids will kill Damon. Katherine then runs back to the Salvatore house, revives Stefan (whom Mikael and Damon had incapacitated to keep him away from the party) and tells him what Klaus said. She tries to convince him to care enough to stop Damon from killing Klaus, because regardless of what he decides, she is going back to see the plan through. <img alt="Katherine 3x09 2-d4fwtjd" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="90" class="thumbimage lzy lzyPlcHld" data-src="http://images1.wikia.nocookie.net/__cb20120408065934/vampirediaries/images/thumb/7/76/Katherine_3x09_2-d4fwtjd.gif/180px-Katherine_3x09_2-d4fwtjd.gif" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katherine 3x09 2-d4fwtjd" src="http://images1.wikia.nocookie.net/__cb20120408065934/vampirediaries/images/thumb/7/76/Katherine_3x09_2-d4fwtjd.gif/180px-Katherine_3x09_2-d4fwtjd.gif" width="180" height="90" class="thumbimage" />KABOOM!!Added by ElenaSmith14Back at the party, Mikael compels one of the hybrids to grab Katherine (pretending to be Elena) and threatens to kill her if Klaus does not leave the Lockwood house. Klaus, believing that Mikael is bluffing, says to go ahead. Mikael then stabs Katherine, who falls down apparently mortally wounded, right as Damon jumps Klaus. Much to Mikael's surprise, Katherine stands up, throws wolfsbane grenades at the approaching hybrids and flees the scene.

Later, she calls Damon to tell him he had a good plan and confirms Damon's assumption that she's already heading out of town. She hangs up with Damon and turns to Stefan, who is in the passenger seat. He asks Katherine why she, who has wanted Klaus dead for 500 years, would stop a plan to kill him just to save Damon. Katherine says she did it not just to save Damon, but also Stefan's humanity. He doesn't believe her, reminding her that she only cares about herself. Katherine tells him he knows that's not true, and that despite everything that had happened, she did love Stefan and Damon. <img alt="Kat3x09" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="104" class="thumbimage lzy lzyPlcHld" data-src="http://images4.wikia.nocookie.net/__cb20111113090245/vampirediaries/images/thumb/d/d5/Kat3x09.jpg/180px-Kat3x09.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Kat3x09" src="http://images4.wikia.nocookie.net/__cb20111113090245/vampirediaries/images/thumb/d/d5/Kat3x09.jpg/180px-Kat3x09.jpg" width="180" height="104" class="thumbimage" />Katherine talks to Stefan about humanityAdded by LittlemisskatherineKatherine then says that humanity is a vampire's greatest weakness, and no matter how hard one tries to suppress it, it keeps trying to fight its way back in - and sometimes, she lets it. Stefan confesses that he doesn't want to let his humanity back in after everything he has done. Katherine says that he must, because she needs him to get angry enough at Klaus to do what she has planned next. She convinces him to steal the coffins that Klaus keeps his family in, before she herself puts as many miles as possible between her and Klaus.

Katherine has not been seen since she left town.

She torments Elena, telling her they're both the same and that she deserves to die. She proceeds to tell Elena that now that she’s a vampire, Stefan is going to hate her, too. Later, Elena finds herself walking to the Wickery Bridge with Connor on one side and Katherine on the other, asking her if she's ready to die yet and telling her she can't take back what she's done, that she's a monster who deserves to die.

In A View To A Kill, Jeremy mentions Katherine, saying, "We might as well look up Katherine Pierce and see if she wants some company in hiding, 'cause he (Klaus) will come after us!"

In Into the Wild, unknown to the viewers or characters, Katherine kills the mysterious attacker to save Jeremy. <img alt="Katherine-4x14" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="126" class="thumbimage lzy lzyPlcHld" data-src="http://images1.wikia.nocookie.net/__cb20130215150606/vampirediaries/images/thumb/3/36/Katherine-4x14.png/180px-Katherine-4x14.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katherine-4x14" src="http://images1.wikia.nocookie.net/__cb20130215150606/vampirediaries/images/thumb/3/36/Katherine-4x14.png/180px-Katherine-4x14.png" width="180" height="126" class="thumbimage" />Katherine returns.Added by Noctis Lux KaelumIn Down the Rabbit Hole, Katherine makes her dramatic return. Unseen by the characters or viewers, she kills Massak and presumably steals the headstone from him. Later, she confronts and attacks Elena in the caves, defeating her and switching clothes with her. As Vaughn is about to finish Jeremy off, “Elena” swoops in to save him. She is about to bite Vaughn and kill him when Jeremy reminds her of the Hunter’s Curse; instead she just knocks Vaughn out. Katherine continues to pose as Elena while Jeremy begs her to heal Bonnie with her blood to save her, but “Elena” insists they must raise Silas and get the cure first. Growing impatient, Katherine reveals her identity and grabs Jeremy, slits his wrist, and puts it in Silas’ mouth, causing Silas' eyes to open. To speed things up, Katherine bites Jeremy’s neck and holds the wound over Silas’ mouth. Silas gains enough strength to raise his hand and hold Jeremy’s head in place, so Katherine grabs the now unguarded cure and flees.

Former MinionsEdit

 * Emily Bennett - She was Katherine's handmaiden in 1864 as well as a powerful witch. Katherine betrayed her when she told the people in town that Emily was a witch.
 * Henry - 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 in the 21st century.
 * George Lockwood - George was a werewolf and the co-conspirator in Katherine's faked death. She and George made a deal in which George helped her escape and told no one of it, in exchange for giving George the moonstone.
 * 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 her power of mind control on Jimmy and compelled him to attack Mason while accusing him of sleeping with his girlfriend, Marla. Mason accidentally killed him, which triggered the curse.
 * Isobel Flemming - Isobel is Elena'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 - Not directly. Isobel asked John to get a device that was taken from Johnathan Gilbert in 1864. John fails to get the device, so Isobel gets it herself by trading Jeremy for it, whom she had kidnapped. She then gives it to John, who uses it to destroy the vampires that came out of the tomb. Katherine was the one to instigate the plan to kill the tomb vampires.
 * Jenna Sommers - Katherine used mind control on Jenna to spy on Elena and Stefan. After Katherine learns of Mason Lockwood's death, she orders Jenna to commit suicide by stabbing herself, but she survived.
 * Caroline Forbes - Katherine turned Caroline into a vampire, and continued to threaten and manipulate her to do her bidding. She ordered Caroline to keep Elena away from Stefan and occupy her for the day so that Katherine could spend time with him.
 * Matt Donovan - After learning of Mason's death, Katherine uses her power of compulsion on Matt, ordering him to provoke Tyler Lockwood into killing him, in order to trigger Tyler's werewolf curse. She planned to use him along with Bonnie, Caroline and Elena to hand over to Klaus in exchange for her freedom.
 * Sarah - Katherine compelled Sarah to attack Tyler if Matt failed, and when Caroline breaks up Matt and Tyler's fight, Sarah attacks Tyler and he accidentally kills her, triggering the werewolf curse.

Physical AppearanceEdit

<img alt="Katherine-Pierce-3" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="233" class="thumbimage lzy lzyPlcHld" data-src="http://images3.wikia.nocookie.net/__cb20120924212646/vampirediaries/images/thumb/5/54/Katherine-Pierce-3.png/180px-Katherine-Pierce-3.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Katherine-Pierce-3" src="http://images3.wikia.nocookie.net/__cb20120924212646/vampirediaries/images/thumb/5/54/Katherine-Pierce-3.png/180px-Katherine-Pierce-3.png" width="180" height="233" class="thumbimage" />KatherineAdded by Cori11Almost every character that has met both of them have remarked that Katherine looks identical to Elena; indeed, they are both doppelgängers of their common ancestor Tatia. As such, 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.

The simplest way of distinguishing Katherine from Elena is in observing basic cosmetic differences: Katherine favors a curly hair style, while Elena typically wears hers straight; Katherine often pairs a sensually cut outfit with heels, while Elena is usually seen wearing comfortable, practical options like jeans, T-shirts and sneakers; and Katherine tends to wear more makeup than Elena.

However, there are subtler differences between the two that only a keener eye can detect. Katherine's eyes seem to be a shade darker than Elena's, having a smoky, shadowy appearance; where Elena's eyes are guileless, Katherine usually seems to be hiding something behind hers. 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. Even her speaking voice seems harsher, more cutting than Elena's.

HumanEdit
In her early life, Katherine was a young and attractive girl who was punished by her family for immoral behavior. After she was banished from Bulgaria, she relocated to England and seemed quite capable of making independent and intelligent choices. After she met Klaus, discovered that he and Elijah were vampires and that Klaus planned to sacrifice her in a ritual, she escaped them and ran for her life. On her way she even conned Rose into turning her into a vampire, securing at once the means to outrun Klaus as well as his eternal ire for thwarting his plans.

VampireEdit
<img alt="KatherineChicago" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="250" height="337" class="thumbimage lzy lzyPlcHld" data-src="http://images1.wikia.nocookie.net/__cb20120713142804/vampirediaries/images/thumb/9/93/KatherineChicago.jpg/250px-KatherineChicago.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="KatherineChicago" src="http://images1.wikia.nocookie.net/__cb20120713142804/vampirediaries/images/thumb/9/93/KatherineChicago.jpg/250px-KatherineChicago.jpg" width="250" height="337" class="thumbimage" />Added by KlausHybridAfter 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 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. 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.

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.

Powers and AbilitiesEdit
Some of these powers are more potent when the vampire gets older and feeds on human blood.
 * Super Strength - Vampires are much stronger than humans and grow stronger with time. Even new vampires who are still in transition can toss a fully grown human across a room with great speed and force. Their strength is also more powerful then werewolves that are not in wolf form.
 * Super Speed - Vampires can accelerate their movements to cover short distances in an instant, faster than the human eye can see. When running across long distances, they appear as vibrating blurs of motion.
 * Emotional Control - The supernatural ability to control and manipulate the emotions of one's self.
 * Dream Manipulation - Vampires can control dreams and subconscious. The vampires can produce and modify dreams, bestow nightmares or lucid dreaming. Other effects of this ability is the distortion of reality and trapped in the dreams.
 * Heightened Senses - They can hear whispered conversations, even ones in far off buildings, smell blood, and see in total darkness.
 * Mind Compulsion - Vampires have the ability to control minds, plague people's dreams, and alter/erase human memories.
 * Immortality - A vampire stops aging once turned. Upon their transformation, vampires then on become immune to all conventional illness, disease, virus and infection. The only known disease or infection that can kill a vampire is a werewolf bite.
 * Healing Factor - Vampires can snap their finger bones back into place after being broken and have been seen to fully recover from gunshots, stab wounds, and torso impalement.
 * Lapis Lazuli - She possess a Lapis Lazuli necklace that she later turned into a bracelet that enables her to walk in daylight without being harmed.
 * Mithridates of Vervain - After her plan was almost stopped in 1864 after ingesting vervain in Stefan's blood. Katherine ingests vervain every day, causing it to have less an effect on her than other vampires.

WeaknessesEdit

 * Vervain - When ingested, vervain causes a vampire to become severely weak and feverish. Also, If a vampire's skin is exposed to vervain, it can result in burning them. If a vampire drinks vervain on a regular basis, they can build an immunity to it.
 * Wood- If a vampire is wounded by wood it will cause the vampire to become severely weak and if a vampire takes a wooden stake through its heart it will result in death.
 * Fire or Sunlight - Any exposure to fire or sunlight will result in death to a vampire.
 * Heart Extraction - The act of removing a vampire's heart will result in death.
 * Werewolf Bite - The bite of a werewolf is extremely lethal to normal vampires.
 * Magic - Witches are able to give supernatural aneurysms that cause the blood vessels of vampires to explode.
 * Decapitation - The act of dismembering or removing the head of a vampire will result in death.
 * Uninvited Invitation - Vampires cannot enter a house without being invited in. If they are in the house without being invited in they will become disoriented.
 * Vampire Bloodline - Vampires who were turned by an original who turned others will die if the original is staked by the white oak stake.
 * Hunter's Curse - If a vampire kills a member of The Brotherhood of the Five then they will be tormented by the hunter until they kill themselves or if the hunter is replaced then they will be free of torment

Attitude Toward HumansEdit
<img alt="You will" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="110" class="thumbimage lzy lzyPlcHld" data-src="http://images3.wikia.nocookie.net/__cb20121230163825/vampirediaries/images/thumb/3/37/You_will.png/180px-You_will.png" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="You will" src="http://images3.wikia.nocookie.net/__cb20121230163825/vampirediaries/images/thumb/3/37/You_will.png/180px-You_will.png" width="180" height="110" class="thumbimage" />Added by I'm Katherine PetrovaBased on what has been shown in the series, Katherine has no regard for human life; to her, humans are a means to an end, whether as victims to feed on or pawns in a plot for personal gain. The notable exceptions to this general disregard are Stefan and Damon Salvatore.

In 1864, Katherine took sadistic pleasure in demonstrating to a human Damon how a vampire lures in a victim by playing the role of a lost woman in order to stop a coach on a deserted road, anticipating the concern this would draw from its passengers. She fed on and killed her victims without any apparent remorse. In the present day, though she has shown no qualms about harming humans, her violence towards them is usually attended by a vague sense of purpose: she chops off John Gilbert's fingers and stabs him as she infiltrates the Gilbert home; she turns Caroline into a vampire as part of her plan to plead amnesty with Klaus; she maims and kills Aimee Bradley to emphasize how badly she wants the moonstone and compels Matt and Sarah to provoke Tyler into killing them; she knocks out Jeremy to use him to get to Mikael; she kills cemetery visitors in order to feed and awaken Mikael; and she kills various people on the island in order to get to the cure.

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 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 Bennett helps Katherine to repay a debt, but Katherine underestimates the witch's willingness to turn against her after the debt is paid. <img alt="Doppelganger" src="data:image/gif;base64,R0lGODlhAQABAIABAAAAAP///yH5BAEAAAEALAAAAAABAAEAQAICTAEAOw%3D%3D" width="180" height="100" class="thumbimage lzy lzyPlcHld" data-src="http://images2.wikia.nocookie.net/__cb20101002141229/vampirediaries/images/thumb/b/ba/Doppelganger.jpg/180px-Doppelganger.jpg" onload="if(typeof ImgLzy=="object"){ImgLzy.load(this)}" /> <img alt="Doppelganger" src="http://images2.wikia.nocookie.net/__cb20101002141229/vampirediaries/images/thumb/b/ba/Doppelganger.jpg/180px-Doppelganger.jpg" width="180" height="100" class="thumbimage" />Katherine and Elena.Added by Xo12Like most vampires in the series, 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
