|“||I'm really starting to get sick of Elena getting everything I want. I've said it before, I'll say it again, Elena had the life I always wanted. Well, until now. Stefan thought he gave me a choice, run or die, but that's not really much of a choice, is it? After all, Nadia was the only person in this world who really loved me and I wasn't about to let my daughter die alone. But Katherine Pierce wasn't about to go gentle either. I left Elena with a parting gift. If I can't have Stefan then no one can.||”|
Katerina Petrova (Bulgarian: Катерина Петрова), better known as Katherine Pierce, was a witch of the Traveller subculture, the third known doppelgänger of Amara, a former vampire, a major antagonist and one of the main characters of The Vampire Diaries. She was the main antagonist of Season One (through John Gilbert's and Isobel's actions, as both were working for her), and one of the main antagonists of the second, fourth and fifth seasons.
After giving birth to a baby girl out of wedlock around age 16, and being forced to give the baby up for adoption, she was disowned. She was exiled to England, where she quickly assimilated into her new culture and met two nobleman brothers, Niklaus and Elijah Mikaelson. At first, she was attracted to the two brothers. However, she later 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 her blood so she could turn herself into a vampire. Because Katherine was no longer human, she was no longer a candidate to break 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 (which is 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 while they hosted her at the Salvatore Estate. She later fell in love with both brothers, and subsequently turned them both into vampires. When the Town 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 20th century, she continued to keep tabs on Stefan, while still hiding from Klaus. 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. To achieve that end, she turned Caroline Forbes, and tricked Mason and Tyler Lockwood into triggering their werewolf curses, just so they could also be sacrificed in the ritual. She fled Mystic Falls again shortly after Klaus broke his hybrid curse.
After failing to induce Klaus' forgiveness by securing the cure and handing it over to Elijah, Katherine managed to draw Klaus away from Mystic Falls by revealing to him in a letter that a witch in New Orleans named Jane-Anne Deveraux was plotting against him. Now that he has moved to New Orleans to investigate her claim, she has officially returned to Mystic Falls.
She goes on the run for the summer, but when she realized how dangerous it was for her to be human, with all of the supernatural enemies she had made over the centuries, she returned to Mystic Falls. She'd hoped to seek Stefan's and Damon's protection, but was forced to flee again when Silas came looking for her at the Salvatore Boarding House and tried to kill her. Silas revealed to Damon that Katherine's blood became the cure after she had ingested it, which is why he tried to kill her and he wanted to cure himself. She ran from him for weeks, but eventually, Damon helped Silas lure Katherine to the house and fed him her blood, which turned him back into a witch. Though Silas drinking all of her blood should have killed her, Katherine managed to live through it. She learned shortly afterward that taking the cure has caused her body to start rapidly aging in order to compensate for the 500+ years she has been alive, and cast a spell on her deathbed to transfer her spirit into Elena's body, so as to stay 'alive'. After the gang discovers this, Stefan stabs her with the Traveler knife, expelling her from Elena's body, but not before making amends with a dying Nadia. Upon learning she was denied entry to the Other Side, and therefore reunion with her daughter, she was dragged by unseen forces into what is presumed to be a hell of some kind.
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 spell of immortality that was cast on the Mikaelson Family and the curse that bound Klaus' werewolf side. She is also the maternal ancestor of Isobel Flemming and the latter's biological daughter, Elena 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, with whom she was involved, until he effectively ended their relationship by leaving to join his half-brother Klaus in New Orleans.
Katerina Petrova was a member of the Petrova Family.
Katerina Petrova (Cyrillic: Катерина Петрова) was born into a wealthy Bulgarian family on June 5th 1473. In 1490, when she was about 16 or 17 years of age, Katerina became pregnant by an unknown man, and her family disowned her for the shameful birth of an illegitimate daughter. She carried the child to term, but seconds after her daughter's birth, Katerina's father took the child away, claiming it would be better for both of them to never see one another. Katerina was devastated by this and was banished to England, where she quickly adjusted by becoming English. In 1492, she met Trevor, who introduced her to 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 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 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 explains 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 latter months of 1492 to find her entire family brutally slaughtered by Klaus. She knew he had done it as revenge for her escape and subsequent transition. She was last seen weeping over her mother's dead body.
1498 - 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 kills a man outside the French Court of Versaille. Nadia while in search for her mother for information offers to pay a man who witnessed Katherine do this, telling him she's been on the run for 228 years.
372 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 to their existence. Pearl warned Katherine that the town knew about the vampires after discovering an elixir containing vervain, which 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.
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. 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 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.
1920's - 1970's
In 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.
During the 1970s, Katherine employed the talents of the vampire Will, who owned the music club and bar, Billy's, and 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.
In I Know What You Did Last Summer, Katherine is first seen upon a street in Mystic Falls, paranoid and disheveled. She goes to the Salvatore house for help and she talks with Damon. She begs him for protection now that she is human, weak, slow and unable to protect herself against her numerous enemies, to which Damon reluctantly agrees.Whilst she is taking a bath in Damon's tub, Silas imitating Stefan shows up suddenly. They flirt and when they are about to kiss Silas grabs her neck, attempting to drown her and she grabs a razor and cuts his face before running downstairs. Damon stops her, throws her to Jeremy and tells him to take her far away, however not to tell him where he is going. Damon stays in the house with Silas, and Silas reveals the whole truth about Stefan suffering "like he has".
Silas asks him to return Katherine for his brother, Damon makes up his mind and immediately calls Jeremy and tells him to return to the house. As soon as Jeremy turns around, Katherine knows what is happening and demands Jeremy to stop the car, however when he tells her to shut up, she tries to escape causing an accident where she and Jeremy are seriously injured by crashing into a post. She limps from the car, spotting a barely conscious Jeremy who asks for her help, she ignores him and hobbles away, leaving him dying in the middle of the road.In True Lies, after leaving Jeremy to die, Katherine flees into the woods. The morning after, she's leaving the woods and getting sick. Katherine walks to the road where she stops a car. Katherine thanks the woman for stopping and the woman tells her she looks just like Elena, but Katherine insists she's much prettier than Elena. The woman maces Katherine, and as Katherine shrieks in pain, the woman pulls out her phone to text Silas. Katherine angrily tackles the woman, smashes her phone, and knocks out the woman, and then Katherine shrieks again in pain from punching the woman, since she's used to having her super strength and not feeling pain. A gun loading is heard behind Katherine and she looks over to Matt, who tells her it looked like it hurt, but his gun will be more effective. Matt and Jeremy take Katherine and keep her out of sight since Silas has the whole town hunting her. They give her some clothes since she was in a robe and Matt begins to tie her up. Katherine compliments Matt on his eyes, telling him they made her soft and that she should have ripped his head off when she had the chance.
She asks them if the rope is really necessary and Jeremy reminds her that she almost got the two of them killed and left him to die. Katherine says she was doing what she always does, anything to survive. She also tells them she's been through this a thousand times; she's the leverage, the one thing everyone wants. She says she's now like the moonstone, as Matt settles her in the truck. Later, they stop at the gas station where Katherine says she needs to get out of the car, but Jeremy tells her no. Katherine then complains that she needs to go to the bathroom and should go like a lady. Jeremy unties her and tells her to hurry, Katherine tells him that she's getting sick and is coughing up green stuff and tells him to get her something for it, Jeremy tells her he can't so she begs Matt to do it. As Matt gets medicine for her and Jeremy gets gas for the truck, Katherine goes to the bathroom and sees an opportunity to run. When the clerk in the store sees Katherine, he begins to call Silas as Katherine runs off. Jeremy catches her and tells her to stop running and takes her back to the truck. That night, Jeremy, Matt, and Katherine create a bonfire. She sees a shotgun, but Jeremy tells her not to think about it. Katherine replies that she doesn't know how to use a gun because she didn't need one and that she was much deadlier. Katherine then complains that, after surviving childbirth, the death of her entire family, and running from Klaus, she's upset about being defeated from a sinus infection. After Silas stabs Jeremy (by stabbing himself first), Katherine returns and shoots Silas.
In Original Sin, Katherine decides to accompany Damon and Elena in search of Stefan, after having the same dream as Elena with the possible whereabouts of Stefan. She says that Stefan is also important to her and she jokes in all the way to Damon and Elena about their relationship.
When they get to the place where the doppelgängers saw Stefan, Katherine is asleep in the car. Damon and Elena decide to enter and leave her there. After Katherine enters and meets Nadia, Katherine flees until she meets again with Elena in the forest. They have a conversation and Nadia appears, breaks Elena's neck and takes Katherine. When they are about to escape, Silas arrives. Nadia tells him that she isn't going to deliver Katherine. Silas enters in her head and tries to force her to commit suicide, when Nadia is about to do it, Silas falls to the ground in pain and they flee.
Katherine is rummaging in Nadia's when she enters the room. Nadia is conversing with Katherine when Silas calls her and says she must deliver Katherine. Katherine takes the phone asking what he wants with her and Silas replies: "The cure still exists, and I still want it. It's just running through your veins right now. Your blood is the cure, Katherine."In Monster's Ball, Nadia and Katherine are still at the Motel, hiding from Silas when Nadia gets a call from him. He tells her he wants Katherine, but Nadia refuses to give her up. Nadia continues to tease him about his inability to use his powers, and Silas tells her he can track them through cell phone tracking. Nadia quickly hangs up on him and tries to take Katherine away. Katherine asks her why she doesn't just hand her over to Silas so he can just have his "little sip" of her blood. Nadia tells her that Silas needs every last drop of blood in her body, which will kill her.
Later on, Nadia and Katherine are eating lunch at a diner and Nadia tells her that she's been tailing her for 500 years and that she wants answers, and if she gets them, she'll let Katherine go. Katherine agrees and Nadia tells her that in 1864, she heard about the vampire round up in Mystic Falls, when Katherine sold out her other friends. Katherine tells her about the many horrible things she's done and Nadia asks her if she remembers ripping a mother away from her daughter. Katherine doesn't recall this and Nadia tells her that Katherine killed her mother in Paris in 1645, and that she has been spending the last 500 years hunting Katherine down for revenge. Katherine realises that Nadia does not plan on letting her go. Nadia tells her it's time to leave and Katherine seizes the opportunity to grab a nearby cane and stab Nadia with it in the chest before running off.
Katherine later finds Nadia in an alleyway, trying to get the cane out of her chest without touching her heart and Nadia asks her why she didn't kill her. Katherine says she knows Nadia's story about her mother was false. Nadia says it was a test and that Katherine failed. She says she wanted to get under Katherine's skin and she succeeded. Katherine asks her what game she is playing and Nadia tells her that Katherine really did kill her mother, but it was not in Paris but in England on April 6, 1492. She says how her mother was exiled by her family two years earlier and how Katherine put her mother in noose and threw her off a chair, the same way Katherine died when she was human. Katherine is confused and Nadia reveals that her name is Nadia Petrova, and that Katherine is her mother. She is the child that was born out of wedlock and was taken away from Katherine by her father when she was human. Katherine is shocked to learn this. Later on, Nadia wakes up to find the cane removed from her chest and looks up to see Katherine, and tells her she is a fool for not running because Silas will find her. Katherine says she isn't worried, she is good at running and that Silas doesn't need her until he figures out how to destroy the other side because if he dies as a witch he will be stuck in "supernatural purgatory".
Katherine says she has had a question bugging her for 500 years. She asks Nadia where she was in 1498. Nadia says she cannot remember because she was only 8 years old, and Katherine tells her that by then she had escaped Klaus and went back to Bulgaria. She tells Nadia she searched every village, every cottage looking for her and she couldn't find her. She says she went back for her, and that it's nice to meet her. Nadia begins crying and smiles before accepting a cup of tea from Katherine.
When Katherine arrives at the Salvatore mansion, lifeless Silas on a couch nearby, she's ecstatic in knowing that she may have toppled the all mighty Silas and escaped death for good. But Damon has other plans. After Katherine unsuccessfully pleads for him to spare her (she doesn't want to die after all), Damon shoves her neck down Silas' throat, draining her of her cure-laced blood. Moments later, Katherine suddenly awakens with her heart still thumping: "Am I in hell?"In Handle with Care, Katherine celebrates the fact that she hasn't died by indulging in food when she notices that her hair is starting to gray. She then dyes her hair and moves into Elena and Caroline's dorm room and pretend to be her but Caroline realizes that she is Katherine then she takes her neck Katherine says that her need a place to live, Caroline at first says no but Katherine tells her that she can help with the Dr. Maxfield and Caroline accepts. Later, the professor Maxfield in his laboratory, is conducting experiments with vampire blood, Caroline appears and Katherine takes the opportunity to inject a substance into his neck, the professor faints in the floor. Caroline and Katherine planned drain the vervain in his system to compel him to tell them everything he know about vampires, Katherine takes over and begins to drain blood from the professor, he tells them that the secret society planned to invite Elena to belong the group but for his suspicions that she was a vampire, they desisted, Katherine then takes the decision to impersonate Elena and Caroline stays with the professor.
She later attends a gathering at Whitmore House posing as Elena to make people believe that Elena is human, she meets to Aaron and begins to ask him questions about the secret society but Aaron seems to have no idea what she's talking about. When they are talking, she loses her tooth while eating the food.
Katherine then suspects that she may be dying and goes to Dr. Maxfield for help. She tells him the truth that Elena is her doppelganger and tells him that he has to help her to not die.In Death and the Maiden, Katherine is in the laboratory of Dr. Maxfield asking him help prevent her aging but he tells that she were turned into a vampire 500 years ago and now that she is human the time is catching up with her, he says that he can't do anything to stop it and that If it continues at this rate, she have a few months of life, he leaves and Katherine is very frightened by that.
Later, Caroline is at Whitmore College and she meets Nadia, they are talking and then comes Katherine, Nadia tries to tell Caroline that Katherine is her mother, but Katherine interrupts her and doesn't permit, Caroline leaves and leave them alone.Nadia wants to know the reason for her abandonment again but Katherine says that she never abandoned her, she say that Nadia was snatched out of her arms at birth because her father thought she was a knocked-up and second of all, that it's been 500 years and that isn't required have to do the whole mother-daughter bonding thing.
Katherine helps with Qetsiyah's spell but exchange for help with the issue of aging, Qetiyah accepts make a spell to stop it but after to resurrect to Bonnie, Katherine is agrees. Katherine, Amara and Elena are ready to perform the spell, they have to give some of their doppelgänger blood for to do the spell, Qetsiyah cut their hands and put their blood in Bonnie's grimoire, when they are about to complete the spell, are interrupted by Silas.
Later, Katherine is trying to stop the blood coming out of her hand and Caroline arrives, Caroline give her blood to Katherine]]When Katherine is trying to clean her blood after being cut by Qetsiyah in his hand,Caroline offers her blood to cure she but Katherine can't drink vampire's blood. After, Katherine finds Qetsiyah alone in the mansion and she says it's time to do the spell, Qetsiyah tells her that she not going to help her and Katherine realizes that Qetsiyah is dying bled, she screams for help but Qetsiyah dies in her arms.
Later in the college Caroline is preparing her room for Bonnie too, then Katherine arrives and understands that she has to go. She looks for her bag but not found it, Nadia appears with her bag and tells Katherine that she will travel to Prague and she want that Katherine fence with her, Katherine says that all it is a fantasy, that she would rather rip her own heart out than do more mother-daughter bonding with she. That she is human now, so it wouldn't really be that easy. She says that don't want to know her, Nadia is very sad for that and then Katherine say that she never gonna see her again, Katherine leaves the room.
In Dead Man on Campus, Katherine was the one to help Matt with his problem. She explained him to what Travellers are- they’re a faction of witches that heavily believe in the spirit world. What they did to Matt was attach themselves onto his spirit like a parasite. Lucky for Matt, Katherine also happens to know who else can help him out, her daughter.
Katherine needs Stefan’s help as part of her plan with Matt. After sweet talking and then moving onto guilt tripping, when the first didn't work, she got him to agree. He should have waited until she told him the whole plan because he sure is shocked to be formally introduced to Nadia of all people.
Nadia, Katherine, and Stefan are waiting in one of the store rooms when Matt comes in. Nadia calls forth her boyfriend out of Matt so Katherine can demand answers. Nadia through they’re only mission was to kill Silas when that was just half of what Gregor came to Mystic Falls to do. He was sent to Kill Katherine. She has a dagger they want. It’s one of the few things that can truly kill a spirit user. It seems she never had a liking for Travellers. Why? Well she believes they’re all judgmental hypocrites. She should know, her father was one. Then kills Gregor. Nadia looked slightly upset with her mother.
Katherine hates running. She’s done before and it’s why she left behind a letter for Nadia explaining why she wanted to kill herself. Stefan saw it and saved Katherine from plummeting to death. She told him she was dying of old age, that the cure had somehow sped up the process. He told her this wasn't the way. Not for the Katherine Pierce. And then he walked away and she smiled.
In The Cell, Stefan was keeping a close eye on Katherine after the suicide attempt. She was writing in a diary at his request because he's worried she will try to kill herself again. But Katherine was just as concerned about him since she overheard some of his PTSD. Stefan didn’t want to talk about it, but Katherine had already invited Caroline over to help.
Katherine tells Caroline that the therapy that she found in a textbook didn’t work. Stefan was still freaking out and Katherine was questioning whether or not Caroline and Stefan had ever hooked up, Caroline answer that they are just friend and Katherine say that her loss becaus e he's great in bed. Katherine pointed out that Stefan is the hero of the story and it can’t be himself that he needs to save.Her solution was to get into the safe with Stefan. He pointed out it was dangerous and she reminded him that she was dying anyway so it didn’t matter if he ate her. Stefan started freaking out and getting upset and Katherine continued to talk him. She suggested that what he was really upset about was Damon and Elena and that he wanted to run away and never come back, but he kept finding excuses not to. She believes his trauma is because he’d rather experience the physical pain than the emotional pain.
To further prove her point, Katherine exposed her neck to Stefan. He got his vampire face on, but her words were getting through to him. They kept getting closer and it seemed like they were going to kiss and that was when Caroline felt the need to open the box because she thought it was too quiet.
Stefan is alone in the room and Katherine goes to see what he’s up to. She helps him straighten up. Stefan tells her that she was right he does need to move on. They kind of drift towards each other. Katherine caresses his chest and then Stefan kisses her.
In Fifty Shades of Grayson, Katherine wakes up next to Stefan in bed. She leans over to cuddle when she notices gray hairs on the bed. She frantically covers herself with a sheet and leaves the room as Stefan looks on amused.
In the woods, Matt is helping Katherine to stay in shape. After some playful banter, Katherine worries when she can't hear what Matt is saying. Nadia arrives with the suicide note that Stefan gave to her. Nadia then slaps Katherine across the face and says that's for trying to "leave" without saying goodbye. In the Salvatore kitchen, Katherine ask Nadia if she's worthy of forgiveness. Nadia thinks that she is worthy and has been thinking about a plan to keep her mother alive.
Nadia suggests that Katherine try spirit possession. Since Katherine's father was a witch from the coven of the Traveller then technincally Katherine is a Traveller witch too, meaning that she could use the spell to live in someone else's body. After Katherine says that Stefan prefers her in her current body, Nadia realizes that Katherine's question about forgiveness was in regards to Stefan and not her. Nadia angrily tells her mother to kill herself and see if anybody misses her.
Later, Katherine is looking at herself in the mirror when Stefan appears. She brings up their night of passion but Stefan says they got swept up in the moment and he can't just forget the last 147 years. Katherine asks what she has to do to get redemption and Stefan says one night isn't enough to erase her history. Katherine repsonds that either one night or an eternity and he still won't look at her like he looks at Elena. As Katherine begins to leave, Stefan stops her and clutches her hand. He says that he's sorry that she's dying and she replies that she is too.</span>
Katherine calls Nadia and wants her to resume the plan of switching bodies. As they're talking, Katherine begins to have chest pains and doesn't answer Nadia back. As Nadia calls at her, she suffers a heart attack and falls down the stairs.
Katherine is dying in 500 Years of Solitude. The episode starts in earnest in a flashback. Bulgaria. A pregnant, human Katherine is having the contractions of childbirth. The baby is born, and Katherine is told that it is a girl, and begs to see her baby as they take her away. Katherine’s father tells her that the baby will be better for it, and Katherine cries on her mother’s shoulder. Katherine cries because they won’t let her even hold her baby. She attempts to get up and grab her baby from her father, but her mom stops her, and Katherine cries some more. Stefan explains that the doctors think that Katherine had a heart attack. Nadia says that Katherine won’t die of a heart attack. Stefan tells Nadia that Katherine is dying. He’s compelled the doctors to let him take her home so she’ll be comfortable.Upstairs, Katherine asks Stefan if they’re talking about her. Stefan says that they’re “reminiscing” trying to gloss it over a bit for her. She says that she probably deserves it. While they’re talking, she’s looking at her hands and asks him if her hand looks wrinkled to him. He says it looks fine. Katherine tells him that if she “starts to sag. Anywhere,” that he’s to slit her carotid artery. Stefan accuses her of being vain, and she says that she’d rather go glamorous. Then, she’s convinced that she sees an age spot on her hand, and Stefan tells her it isn’t one and holds her hand. Katherine asks Stefan why he’s being nice to her. He says that since she’s dying, he can “muster” some compassion for her.
Katherine is not only dying but plagued by visions that have haunted her for her entire life. Her daughter gets ripped from her arms and Klaus murders her entire family. Damon returns to his more evil ways by trying to kill her and settling for taunting her psychically. Katherine is haunted by her past mistakes and it only gets worse as Damon manipulates her mind. She revisits the first time she ever saw Stefan and realizes that the doppelganger connection might be truer than she thought.
Jenna reminds Katherine of how Katherine compelled her to stab herself in the stomach, and Damon appears in her place and reminds Katherine of how he had to compell Jenna to believe that she has just walked into the knife. Then Uncle John is there, “Hello fingers. Goodbye fingers.” And then Elijah is where John was, sitting on the bed next to Katherine. She reaches up to touch his face, and then its Damon again. Damon tells her that no one is coming to say goodbye, because no one cares. Nadia has slinked into the room behind him, snaps his neck, and saids that she cares.
Nadia, Mia, and Katherine are discussing the words to the spell that have to be spoken for Katherine to jump into Nadia's body. Nadia wants her to repeat the spell, but Katherine won’t. Finally, Katherine asks for a moment alone with her daughter. Katherine tells Nadia that letting her father take baby Nadia away from her is her biggest regret in life. She should have fought harder for her. She says that she spent the next 500 years making sure that she didn’t make that mistake again. She says she’s had a long life and finally got to know her “beautiful daughter.” Katherine tells Nadia that she has spent the last few centuries searching, and Katherine doesn’t want that life for her. She wants her to live. Damon has regained consciousness on the floor, but he doesn’t let on. His disbelief at this conversation is pretty evident on his face. Katherine says that she’s made selfish decisions all her life, this is just another one. Nadia gets mad and says that she won’t sit by Katherine’s side just to watch her die and storms out. Katherine stabs herself with another does of sedative and her eyes close.
Stefan sits down on the bed. Katherine says something about how these drugs she’s on are “hard core.” Stefan tells her to close her eyes, that he’s come to say goodbye. Katherine says that she doesn’t want to, because she wants to see him. He tells her that she will, and they go into her memory/dream thing of coming home and finding her family dead. He asks her if this is really the memory she wants to revisit. She says that it was the worst day of her life, andthat Damon told her it was all her fault and that she deserves it. She says that she thinks Damon was right, she doesn’t even deserve to be loved. Stefan disagrees and asks her to open her mind to him. Stefan takes away all the blood and gore of the scene, and all the bodies and then leads her to a crib, with a crying baby in it. We’re led to believe that it’s baby Nadia laying there. Stefan tells her that she’s a 17-year-old girl and none of this is her fault. The baby cries again, and Katherine goes to the crib. There’s a bright white light, and Katherine seems to go into it.
Stefan says, aloud, “Goodbye, Katherine” and Elena walks in and asks if she’s gone. Stefan tells her that not yet, but she won’t open her eyes again.
She dies for a second but refuses to go and literally makes her own heart beat again. Elena is standing over her newly conscious body and gives Katherine her heartfelt and sweet forgiveness. Katherine convinces her, and the audience that she’s ready to die. Then grabs Elena and does the traveler spell to steal her body. The episode ends with Katherine impersonating Elena.In The Devil Inside, she fights with Elena over her body. She needs her corpse to possess Elena's completely but doesn't know where it is. She compells Matt to find out facts about Elena and tries to convince everyone that she is Elena. Nadia is going to find out where her mother's body is and needs to leave her alone so she traps her to the bed just in case Elena fights and breaks through. Elena almost breaks free, but it is too late as Nadia is already back and pushes her aside so Katherine gains the control again. As others are already worried about Elena, Katherine goes to the Matt's party in order to find information about her body and to be less suspicious about Elenas solitude. She talks with Stefan pretending to be Elena and asks him if he is heartbroken over Katherine's death and is upset that he is not. She asks him if they should have funeral or at least some flowers as she tries to find out about where her corpse is and at the same time hopes that Stefan would feel sorry for her death. Stefan reveals to her that Damon put her body to the place it "should have been long time ago". Katherine figures it means the tomb where Damon put her before, to punish her from 146 years of wasted waiting as she was not there.
She informs Nadia and they find her body and start ritual to make Elena's body her's but Elena breaks through and intervenes, hurting Mia who is casting the spell. Elena then runs off, but Katherine has changed the password so she can't call for help. Elena runs to Damon but is too late. As Elena didn't kill Mia she ends the spell and Katherine takes her body over. Katherine takes now permanent control over her body. Damon tries to fix thing between him and Elena, but as Katherine has control she breaks up with him. Katherine decides to stay in Mystic Falls to win back Stefan.In Total Eclipse of the Heart, Katherine enjoys her life as Elena. She keeps Nadia close to Matt so she could find out all she needs about Elena and she is devoted to win Stefan back. She is trying to find a way to make his way closer to him and when Stefan calls her and wants to talk, she invites him to the Bitter Ball. They share a dance and she tries to convince him that she has given up on Damon and says that she dosn't like the person she has become with Damon and asks if Stefan does. When Caroline pulls her aside and tells her that she should slow down with Stefan she beguns to worry that Caroline might have feelings for him. When she returns to Stefan she sees that Damon has kidnaped Jeremy, she leaves to call Nadia and asks her to find out what would Elena do in this situation and also ask Matt if Caroline has feelings for Stefan. She is very displeased to find out that Elena would do anything to save her brother, because Jeremy's death would be very convenient for her. In need not to break her cover has Elena, she begs Stefan to help her save Jeremy and tells him where he is. They find Enzo with Jeremy and while Stefan is fighting Enzo, she more like pretends to help Jeremy than is really helping. When the encounter is over she asks Stefan about Aaron hoping that it will give her more reasons to apparently give up on him. She asks why did Stefan hide this fact about them and says that they should be honest with each other. Stefan tells her that he used to wish that Damon would mess up so badly, that she (Elena) would give on him, but as he saw that Damon was always there for her, he begun to like the person his brother has become and he doesn't want to lose him. Katherine takes the opportunity and promises to him that she will help him get Damon back, but makes it clear that she is doing it only for Stefan.
In No Exit, Katherine is first seen when she is studying with Stefan as she hopes to win him back as Elena. When Caroline visits Stefan and receives call from Tyler who informs Caroline that Nadia is compelling Matt, who is now missing, she starts to worry and calls Nadia, and tells her to kill Matt if he is danger to her secret. When Stefan decides to go after Damon, she offers to go with him so she could spend more time alone with Stefan. When they stop to tank, she uses opportunity to break his car and make herself dirty, so they could find hotel and get the room and shower, while they are waiting for car to be repaired. When Stefan is getting shower she answers Enzo's call who asks for their help, since he is trapped with Damon and hopes they could save them, before Damon kills him or he is forced to kill him. Katherine doesn't rush to tell this information to Stefan and instead of it she focuses on seducing Stefan. They kiss, but Stefan breaks it and tells her that it is wrong, since she just broke up with Damon. While Stefan leaves her alone she calls Nadia and asks who does she thin Stefan loves more: Damon or Elena, and reveals to her that she hopes that if she gets Damon to feed on her it would leave Stefan no choice, but to kill him to save her. When They find Damon, she steps into the house and pretends that she loves him and then cuts herself in front on him, forcing him to fight his urge to feed on her because he loves her. When Damon loses control and feeds on her she kicks the stake infront of Stefan and tells him that Damon is killing her, essentially asking him to kill Damon to save herself. Her plan backfires, when Stefan doesn't kill him, but cut's himself asking Damon to feed on him instead. Later she meets crusty Nadia, and tries to celebrate her good mood about her success with Stefan and her disappointment that Damon is still alive, but then she finds out that Nadia got bitten by Tyler and she is dying.
In Gone Girl, Katherine told Nadia she couldn't ask Klaus for his blood because he wouldn't help her anyway. Instead, she'd called Wes, who allegedly was willing to study Nadia's blood and create the antidote. He took some blood, and Katherine vowed to be a better mother, which meant saving her daughter's life. Caroline called Katherine and tried to get her to come help set up for a surprise birthday party for Bonnie but Katherine said she had to make arrangements for Aaron's funeral, which trumps a birthday. Exhausted anchor Bonnie tried to get her to meet her for coffee, but Katherine said she was at the spa buying Bonnie a gift certificate for her birthday. Katherine wondered why they were being so clingy. She phoned Damon, who told her to come on over and talk about what happened at the farmhouse. Katherine knew Damon would never put Elena in that danger again, so they must know she's Katherine.
Katherine takes Nadia to the church and tells her that they will leave once she is better. When looking for Wes, she found him dead. She then got a call from Stefan, letting her know that he has Nadia. Katherine stormed in the Salvatore Boarding House and said she was there to see her daughter. As Nadia took her last breaths, she said, "My mother's name is Katherine. I'm looking for her." I teared up. Katherine told her she found her, she's right there. Nadia said her mother's a liar, a murderer, she manipulates, and she betrays, and she'd do anything to survive. Nadia just kept saying she's looking for her mother. Katherine wanted to show her what her life should have been like. She said they had a little cottage. It was an ordinary summer day. Nadia had built a fort that she would show her mother in the morning. Katherine told her good night and to sleep well. And then Nadia died. "Your mother loves you," Katherine said, with a tear falling down her face.
As Katherine struggles with the realization that her daughter is gone for good, Nadia’s ghosts appears before them all and looks on with great sorrow as her mom utters the exact phrase she’s always longed to hear. She seems ready to move on but also upset at the sight of her mom grieving. ‘Anchor” Bonnie, who is overcome with compassion, extends her hand and Nadia takes a hold of it and enters the Other Side. Suddenly, Katherine is left on her own and it’s time to pay the piper. She kisses her daughter goodbye, closes her eyes, and covers her body. Then she stands up resolutely and…tries to make a dash for it, unfortunately for her, Damon’s on the other side, blocking the exit. “Hello, Katherine. “Did you really think I’d miss this?”
Realizing she’s been beaten at her own game, Katherine concedes. “So who’s got the knife? Which one of you gets to kill the elusive Katherine Pierce once and for all?” Uncomfortable silence falls over the room and you can almost hear crickets. Katherine, annoyed that they’re being cowards. She decides to have her fun while she can and gets the party started by dishing out something called a reality check: she changed all their lives for the better, whether they care to admit it or not.
To Tyler: “Are you gonna do it? Because I triggered your werewolf curse? Gave you an identity? Made you matter? If I’d never walked into your life, you’d be a washed up nobody with a boozy mom and a temper problem.”
To Caroline: “And you. Well, I’m not worried about you offing me. We both know I made you better.”
To Matt: “The one girl here who actually appreciates how gorgeous you are and you’d shove a knife in her heart? I don’t think so. Matty, Matty, Matt. You will definitely go down as the best night-I-never-had. Oh well.”
To Jeremy: “Well, little Gilbert, it was to have a brother for a second there — when you weren’t being so damn annoying.”
To Bonnie: “Bon Bon, no need for goodbyes. I'll see you on the flip side.”
To Damon: “Damon. Oh how you’d love nothing more than to drive that blade right through me.” I know. But I never got to say what I needed to say to you. I’m sorry. You blame me for who you are, and I’m sorry. I’m sorry I turned you. I’m sorry I drove you to abandon the war. I’m sorry you didn’t get to die a forgotten nobody on a bloody battlefield. I’m sorry your father didn’t get to live another day to be disgraced by you. I’m sorry I gave your life purpose. Drive. Passion. Desire. I’m sorry you are who you are because I taught you how to love.”
To Stefan: “Well, Stefan, I’ve always wondered what it would be like to be loved by you, and I think we both agree that for a fleeting moment your feelings were real. This has truly been the role of a lifetime. I love you Stefan. I’ve always loved you.”
Just as she confesses her affection for the younger Salvatore, Stefan stabs her with the Traveller knife. “I guess this is how our love story ends,” she gasps, her voice ridden with hurt. She collapses onto the floor, right next to daughter’s body. Before going over to the Other Side, Katherine fills Bonnie in on yet another secret: she left Elena the worst parting gift ever. Apparently Katherine didn’t like being forced to choose between running or spending time with her ailing daughter — she’s wild and independent and doesn’t like being bossed around, ya heard? “Katherine Pierce wasn’t about to go gentle,” she states. And what does Katherine hate more than anything else? The idea of cute and sweet little Elena winning. So while at Dr. Wes’ decrepit lab, Katherine finds the syringe containing Nadia’s blood sample and also a tape recorder in which Dr. Wes revealed that the werewolf toxin would be useful in making the vampire virus contagious, and freaking injects into Elena’s body. Katherine could care less about the repercussions of her actions. If she can’t have Stefan, no one can. She flashes an haughty smile and decides it’s time for her to head on over to the Other Side. She grabs hold of Bonnie’s shoulders but nothing happens. ‘Are you broken?’ she demands via her furious expression. Bonnie doesn’t know what’s going on either and why this particular journey has malfunctioned. Suddenly, a gust of wind extinguishes the candles in the church and the doors burst open. Howling air whips around the sacred site and some powerful, unseen force blasts Katherine backwards. She claws desperately at the ground but it is to no avail.
In While You Were Sleeping, while Elena was reading her diary, she saw an entrance Katherine wrote. She made a brief appearance in Elena's mind as a reconstition of the motel scene with Stefan.
The Originals Series
Katherine was possibly mentioned for the first time in The Originals by Elijah in Apres Moi, Le Deluge, Elijah explained to Hayley that he had only been in love twice in 1,000 years — Celeste and Katherine (or Tatia) and that when he finds it, he honors it.
1400's (1st Time Witch)
- "I was you before you even existed!"
- —Katherine to Elena
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.
Present Time (2nd Time Witch)
|“||Do you think that, after all horrible things I've done ... it would be possible to be forgiven?||”|
— Katherine to Nadia
After Elena forced The Cure down her throat when she had tried to kill her, Katherine was rendered a weak human and had to spent two months on the run from all of the enemies she had acquired in her 500+ year lifespan. She enlisted the help of Damon, but was momentarily sold out when Silas offered Stefan for Katherine. After that failed, Katherine was granted reluctant protection under Jeremy, Matt, and Damon from Silas. Her transition to human left her weak, disheveled, and miserable as she struggled to get used to her vulnerability. Katherine's personality as a human is largely the same as when she was a vampire. She maintains her sassiness, insensitivity, independence, pride, selfishness, and sense of self-preservation. She had initially left Jeremy to die after a car crash while on the run from Silas and immediately accused Elena of being Katherine while held at gunpoint. However, Katherine soon starts to show some signs of shifting away from her "psychotic bitch" demeanor. She willingly goes back to save Jeremy's life from Silas despite risking her own survival and agreed to help rid Matt of the passenger inside him named Gregor.
Katherine also becomes slightly less hostile with certain members in the Mystic Falls gang, creating a strained but not entirely unfriendly alliance with Caroline, Matt, and Jeremy. She seems to have a soft spot for them somewhere, shown in her decision to save Jeremy from Silas and most prominently her interactions with Caroline to get Wes Maxfield unsuspecting of her and Elena being vampires in return for using her college dorm for a few days. Katherine also helped Matt with his passenger and went to him to help her put off her death by exercises, though Matt still sticks to the belief "Katherine cares only for Katherine."  She also met her long-lost daughter Nadia Petrova from 500 years ago and has genuine though complicated love for her, even attempting to cut off all ties with her for the sake of protecting her from Katherine's inevitable death since she couldn't be there for her.
Perhaps one of the most marked differences in Katherine's actions is her increased openness with her true emotions and vulnerability, particularly with Stefan. As she was dying of eventual old age after Silas drained The Cure out of her, Katherine falls into a depression with her loneliness and impending death to point she briefly lost the will to survive. Her misery climaxed into a suicide attempt by jumping off a clock tower, but failed when Stefan saved her. However, Katherine's inspired with a will to live through the recent support of Stefan. She becomes emotionally dependent on him in her darkest hours and quickly fell love with him again, admitting that he was the only reason she wanted to live. Katherine's softer sides are made more obvious than ever before, wondering to Nadia if she could be redeemed for her past misdeeds and is worthy of forgiveness; a sharp contrast from her vampire self who had no remorse over anything and justified it as means to survival.
|“||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 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.
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.
- Main article: Katerina Petrova/Appearance
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,especially eye make up.
However, there are 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.
Whenever Katherine pretends to be Elena she dresses very similar to Elena's style and straightens her hair. But she also can’t help but still rock some major cleavage.
- "I went back. For you."
- —Katherine to 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 and although despite her conflicting feelings, she pushes Nadia away after learning of her impending death. Nadia is angered and clearly upset at her mother's attitude and actions towards her, and that she seemingly cared more about earning Stefan's forgiveness than her own. However despite her anger, she wishes Katherine would desire to live longer and is conflicted towards her anger at her for wishing to give up her life, or to be at her side.

- 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 was in 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 in The Originals, Elijah left Katherine behind in Mystic Falls and went to New Orleans after saying and kissing her goodbye, assumingly ending their relationship. Even though he was a hallucination in 500 Years of Solitude, Katherine was happy to see him and had shown to have missed him.

- "Humanity is a vampire's greatest weakness. No matter how easy it is to turn it off, it just keeps trying to fight its way back in."
Based 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.Like 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.
Katherine's attitude towards humans may change as she is human now. Her interaction with humans will increase now as she is a human.
Based on what has been seen, Katherine doesn't really care about her fellow vampires, and would do anything to get things from them. Katherine has been seen to toy with certain vampires as shown with the Salvatore brothers. Katherine has had relationships with original vampires, and betrayed those as well.
She was hiding a long time because of Klaus, whom she feared for his power. She has always proven to be much stronger than most vampires in the series except for the originals. She also is able to manipulate certain vampires very well.
Now as a human, her personality has not changed much as she was as a vampire. But she has become afraid of them as she has people after her and she is not able to defend or protect herself.
Katherine Von SwartzchildKatherine von Swartzschild (born Katerina von Swartzschild) was a young German girl, who was the daughter of Baron von Swartzschild. She was very sickly, weak, and fragile as a young human girl and during her childhood, and was told by a surgeon that she was going to die. After this news, her maid, Gudren, fetched the village vampire Klaus and asked him to turn her into a vampire. He did so, though Katherine had no say in the matter, and she became a vampire.
Believing she was still sick, her father took her to the Salvatore Boarding House to cheer her up. There she met Stefan Salvatore, the younger human son of Conte di Salvatore, and she fell deeply in love with him. However, she also displayed interest in Stefan's elder human brother, Damon Salvatore.
In The Awakening, she said to both of the brothers that the only way to stay in Salvatore Estate was if she chose which Salvatore to marry. She said that she would tell them which one she had chosen for marriage on Sunday in twilight. Katherine first came to Stefan during the night, presumably during lovemaking and she gave him her blood.
However, Katherine also gave Damon her blood as well. Both brothers were furious when they found out that Katherine had given both of them blood and not just one of them, displaying Katherine's coy, selfish and childish tendencies. Katherine told both of the brothers that she refused to choose between the two of them, leading the rivalry and competition between the brothers to heat up even more intensely.
Katherine believed that if she turned both Stefan and Damon, then she, Stefan and Damon could all live happily ever after together. The brothers refused Katherine's wish and it turned the brothers against each other even more. Katherine became extremely distraught and upset by both Stefan and Damon fighting over her, so Katherine decided to commit "suicide". The next day, Stefan and Damon had found her ashes outside alongside her small lapis lazuli ring, which protected her from the sunlight and her dress, along with a note saying that she was selfish.
Damon and Stefan both blamed each other for her death, and ended up fighting each other to death with swords. Stefan and Damon both ended up stabbing each other, and both died. They woke up in their tombs, with their lapis lazuli rings on, having both been transformed into vampires, bounding the Salvatore brothers to each other for all of eternity.
Stefan describes Katherine as being very beautiful, when she first arrives to Mystic Falls, even though he is supposed to be engaged to Rosalyn Cartwright. She and Stefan kissed in the library at the Veritas Estates for the first time. She stays in the carriage house with Emily and she killed Rosalyn out of jealousy. She acts as innocent to avoid being uncovered as a vampire. Katherine was with Damon before Stefan and compelled him to take her secret better. Stefan believed her to have died. He tells Damon that he is wasting away Katherine's gift.
- 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.
- 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.
- Katherine's was born on June 5th, 1473, making her a Gemini.
- Most people use the the Anglo version of Katherine for her name. However Klaus, Elijah, Rose, Trevor and Nadia refer to her by her original name Katerina.
- Katherine's doppelgänger blood could have been useful when she was human, making her a target if Klaus had desired to create more hybrids.
- Klaus is seemingly no longer interested in doppelgänger blood, something he needed for creating hybrids, but has instead reunited with his siblings to New Orleans.
- Silas had been after Katherine because the cure was running through her veins.
- Katerina, Isobel, Rose, and Klaus are the only characters to have an episode named after them.
- Nina Dobrev who plays Katherine Pierce, was born in Bulgaria and speaks Bulgarian. For this reason, Katherine, who was German in the books, became Bulgarian in the series.
- In the books, Katherine von Swartzschild was German, a vampire of great beauty, but also immature, manipulative and selfish. In the TV series, Katerina is Bulgarian, a vampire of great beauty, but is also self-centered and ruthless. Katherine Pierce and Katherine Von Swartzschild are both vain, sadistic and manipulative woman who faked their deaths.
- Katherine Pierce and Katherine von Swartzschild are very much alike; both closely associated with Klaus, evil in Mystic Falls/Fell's Church, have easygoing attitude and hate Elena. The only difference between them is Katerina Petrova has black curly hair with brown eyes, and Katherine von Swartzschild is blonde with blue eyes.
- Rose was the vampire responsible for turning Katherine on the TV series. However, Klaus was the one who turned Katherine in the novels, completely changing the back stories of Katherine and Klaus for the series. Klaus felt emotion for Katherine, so wanted to avenge her death in the novels.
- Katherine was a "birthday gift" from Trevor to Klaus in 1492.
- Katherine's life is seriously affected by Klaus in the books and the series. In the books, Katherine Von Swartzschild becomes insane, paranoid, unstable, selfish, cruel, and sadistic because of Klaus's influence for centuries. In the series, Katherine Pierce becomes the same, but because her child was taken away from her, and her family was slaughtered by Klaus.
- Katherine's parents are the first of Klaus' victims to be seen in the TV series.
- When Katerina first arrived in Mystic Falls, she said she was an orphan who lost her family in a fire. She may have burned down her house with her family inside after they were murdered by Klaus.
- Vanessa Monroe, a research assistant and former student of Isobel, mentions in Bad Moon Rising that Katherine arrived in Mystic Falls in April 1864, but this is inconsistent with Katherine's story that her family perished in the Atlanta campaign fires, which occurred in September of that year.
- Katherine wore a cameo lapis lazuli necklace until the 1920s.
This necklace is seen in all 1864 flashbacks and in 1920s flashback. After this she wears a different necklace, then turns it into a bracelet.
- She is the first of three women in her family to have slept with Damon Salvatore. Both of her descendants Isobel Saltzman and Elena Gilbert have also slept with him.
- Many people have fallen in love with or felt attracted to Katherine. Vampires and humans alike Stefan, Damon, Mason, Trevor and Elijah have all been in love with her. Noah was also obsessed with her. It is thought that the Petrova doppelgängers have an uncanny ability to win others affections, especially from men, as evidenced by all of the love triangles the three Petrova women have been involved.
- Others can usually tell Katherine apart from Elena by their hair, make-up and wardrobe choices. (See Physical Appearance.)
- Katherine is quite adept at disguising herself as Elena. She has been mistaken as Elena by Jenna Sommers on many occasions, which resulted in Jenna inviting Katherine into the Gilbert's home and being lured into a trap after receiving a frantic call from "Elena".
- Katherine used mind compulsion on Jimmy, Matt and Sarah to activate the werewolf curses in first Mason Lockwood and then Tyler Lockwood.
- Despite claiming to know all about The Originals in The House Guest, she did not know that Klaus wanted to become a hybrid, that the dagger and white oak ash would not work on him, or that the curse was fake, until after The Sun Also Rises.
- Katherine is the first vampire shown to be fed on by another vampire.
- She has been absent from Mystic Falls since Homecoming, but came back in Pictures of You.
- She, Damon, Stefan and Caroline have all been bitten by either a werewolf or a hybrid, and were all healed with Klaus' blood.
- Katherine's remorseless behaviour suggests she may have "turned off" her humanity, However she did - deliver Klaus's blood to cure Damon, warn Stefan about how dangerous Klaus was and rescued him from the witch Gloria, alerted Stefan to Klaus's intention to possibly kill Damon - plus her own admission, Katerina may still have human emotions.
- Katherine possibly knew about Tatia, when Elena asked her in Katerina what the Petrova family has to do with Klaus, she understood the concept of creating a doppelgänger. Katerina has never specifically mentioned Talia or any of the other Petrova Doppelgängers, either by name or other reference.
- She is present in Pictures of You, The Originals, She's Come Undone, The Walking Dead and Graduation, and she plays a role in Bonnie's plan to defeat Silas.
- She is the first vampire to be cured of her vampirism and was technically the second oldest living human at 538 years old.
- During Season Five, her continuity as a main character will continue and will indeed be a significant part of the season; unlike how she was a recurring character in the third and fourth seasons.
- Katherine is the 3rd Doppelgänger of the Petrova line.
- Nadia is Katherine's daughter and maybe the reason that Katherine became the person she was.
- Katherine, Nadia, Silas, Klaus, Rebekah, and Elijah all speak multiple languages.
- It is hinted in Katherine's letter to Klaus that she knows about Marcel and Hayley and the baby, "I have caught wind that there is a witch in New Orleans named Jane-Anne Deveraux plotting a move against you. Hunt her down. What she has to say will rattle you so deeply to your core that chasing little old me will be the least of your concerns".
- In the novels, Katherine's relationship with Klaus is very different from the TV series. Klaus is the one to save her from a certain death as a human by turning her into a vampire, and, shortly after her death as a vampire, he brings her back to life in order to fight the Salvatore brothers and their friends. Katherine is shown to have been loyal to Klaus for centuries, although it is impied that her companionship with him drove her insane and made her selfish and cruel.
- As of Fifty Shades of Grayson, it is revealed that Katherine was never human, but a Traveller Witch, as she received the gene from her father.
- She suffered from a heart attack in Fifty Shades of Grayson.
- She's currently the oldest witch alive.
- Katherine performed her first spell as a Traveller in 500 Years of Solitude.
- Katherine admitted, that Stefan is her one true love in The Devil Inside.
- Katherine and all her known doppelgängers and predecessors's names all end with an A, Amara, Tatia, Elena and Katerina.
- Both Katherine and Elena were terrorized and eventually drained of blood by powerful immortals in order to achieve a certain goal (Klaus drained Elena to break the Hybrid Curse and Silas drained Katherine to cure himself of immortality).
- Katherine is the first doppelgängers to possess and take over the body of her doppelgängers descendant.
- Katherine is the 9th main character in the TVD & TO universe to die after Vicki, Jenna, Alaric, Jeremy, Bonnie, Silas, Davina and Sophie.
- Like her Ancestor Amara and her Doppelganger Elena, Katherine had a close relationship with a Bennett Witch. Amara was Qetsiyah's handmaiden, Bonnie is Elena's best friend and Emily was Katherine's handmaiden.
- Ironically in ancient times, Qetsiyah's handmaiden was Amara, Katherine's ancestor, but in 1864 Emily Bennett was Katherine's handmaiden, Qetsiyah's descendant
- A Day in the Limelight - has an episode named after her, plus frequent flashbacks into her origins.
- Briarpatching - Katherine uses this technique on Damon when she tells him not to dagger Elijah as she would be stuck in the tomb forever.
- Magnificant Bastard - "Plan B"
- Katherine fits the Light Feminine And Dark Feminine trope, especially with Elena. Elena and Katherine are both doppelgängers who share an uncanny physical appearance. Elena is the Light Feminine (good, immoral) and Katherine is Dark Feminine (bad, moral). Both share a common love and interest in Stefan and are often in competition with each other for his affections.
