He is first mentioned in a conversation between Rose and Stefan when she warns him about the Originals. Elijah tells Elena that Klaus is believed to be the most hated and feared of all the Originals and those who fear him are desperate for his approval. Over the centuries, Klaus has become a recluse who confides in and trusts only the few members of his inner circle.
For over a thousand years, Klaus had been trying to break a curse placed on him. He created the myth of the sun and moon curse in order to find the moonstone and the Petrova Doppelgänger, both of which were needed to break the actual curse. His goal was to liberate his werewolf side so he could sire his own super race of vampire-werewolf hybrids.
In 1492, he finally got his chance to break his curse when he met Katerina Petrova, the final piece necessary to break the curse. However, Katerina managed to foil his plan to use her in the sacrifice by turning into a vampire. For the next 500 years, Klaus searched for a way to break the curse without the doppelgänger, forcing generations of witches and warlocks to help him. During his search for a way to break the curse, Klaus hunted down his family and neutralized them. He also hunted Katerina Petrova, who had escaped him and stolen his moonstone.
Klaus is also the first undead creature in the history of the series universe known to have impregnated a woman.
Klaus is a member of the Mikaelson Family, and a member of an unknown Family of Werewolves.
With Silas and Qetsiyah now dead, Klaus is the most powerful immortal/supernatural being in the series universe.
The Middle Ages
Niklaus was born to Esther and an unknown man in a small village that would eventually become known as Mystic Falls. Niklaus has six half-siblings and a step-father named Mikael, a wealthy landowner who moved with his wife Esther to the New World after their home village was devastated by a plague. Klaus was close to his family with the exception of Mikael, who was inordinately hard on Klaus.
Many years before, his mother had had an affair with a man from the neighboring village, whose inhabitants were known to be werewolves.
When Niklaus and his brother Henrik went to see the wolves transform, Henrik was killed by one of the wolves and Esther performed a spell (called The Immortality Spell) which transformed Niklaus, his siblings and his step-father into vampires.
When Niklaus made his first human kill, his werewolf gene was activated and he became hybrid, thus revealing Esther's infidelity. Mikael then hunted down and killed Niklaus father and his entire family, not realizing that doing so would ignite a war between vampires and werewolves that has been perpetuated across the ages. Soon after becomig a Hybrid, Mikeal had Elijah help hum restrain Niklaus and Esther to use her Dark Magic to place a curse on him; which forced his werewolf side to lie dormant and then rejected and abandoned him. In retaliation, Klaus murdered his mother and framed Mikael for the act.
After killing Esther, his family scatterd and Niklaus stayed behind with Rebekah to bury Esther. Rebekah promiced to never turn her back on him, like Esther did and so did Elijah. They swore to eachother stay together always and forever.
Klaus was with Elijah and Rebekah in 1114 AD Italy when they met a man named Alexander, a vampire hunter who was part of The Five. They spent a lot of time with him -- the brothers in order to discover his plans for killing vampires and Rebekah because she loved him. Alexander did not seem to suspect them; they wore their daylight rings, allowing them to walk in the sun without burning, unlike the vampires whom Alexander killed on public display. However, when Klaus and his siblings were invited to a party at Alexander's home, the members of The Five daggered them in their sleep. Klaus, with half werewolf lineage, could not be neutralized by the White Oak Ash Dagger and upon awakening killed all of The Five, including Alexander. He undaggered his siblings (except for Finn) and found out from Rebekah that the weapon Alexander had told her about was a "cure" for vampirism. As a result of slaying The Five, Klaus was forced to endure 52 years, 4 months and 9 days of the Hunter's Curse - torturous hallucinations that haunted his dreams and every waking moment in an attempt to make him kill himself, but unable to, given his near-indestructible state.
According to Elijah, Klaus has lost much of his humanity, hiding his loneliness with cruelty.
Klaus was an English nobleman during the late 15th century when he met Katerina Petrova, the doppelgänger whose appearance he had been awaiting for five hundred years. Planning to use her in the ritual, he had kept her entertained until the full moon, but she learned of his plan before it could take place and escaped, taking the moonstone with her. As she fled, she encountered a vampire named Rose, whom she tricked into turning her into a vampire, thus ruining forever Klaus' plan to use her to break the curse. After Katerina turned into a vampire, Klaus assumed that her family line ended with her and that his chance to break his curse was gone forever. In retaliation, Klaus traveled to Bulgaria and murdered Katerina's entire family for her defiance.
18th Century -20th Century
Having fled the Old World for unknown reasons, Klaus, along with Rebekah and Elijah, sailed across the world, through the Mississippi River and arrived in New Orleans, 300 years from the present. Upon arriving off the coast of New Orleans, they slaughtered all the men who boarded their ship, but left one alive to question and carry their luggage.
In 1918, Klaus, Rebekah and Elijah had to leave New Orleans. In Reigning Pain in New Orleans it is suggested by Rebekah that Marcel was the cause of Mikael finding them. During the 1920s, Klaus and his sister Rebekah were on the run from Mikael, who they had been running from for a 1000 years. The siblings were in Chicago in 1922 where they met the vampire Stefan Salvatore, whom Rebekah fell in love with. At first Klaus hated Stefan, but he grew to like him once he discovered that Stefan was a Ripper and they became good friends. One night, the speakeasy they were at was attacked, apparently by the police, though it turned out the raid was led by Mikael. Before he left, Klaus compelled Stefan to forget him and Rebekah. Later, when he and Rebekah were about to leave Chicago, Rebekah told Klaus that she was tired of running and wanted to be with Stefan. Klaus then forced her to choose between him and Stefan; she chose Stefan. Afraid of being left alone, he neutralized his sister with a White Oak Ash Dagger, then took her body with him in a car and left Chicago.
In Always and Forever, Klaus is first seen during a flashback to the early 18th century. A crew is searching through an "abandoned" ship and finds the two coffins containing Klaus' neutralized brothers, Finn and Kol. Elijah and Rebekah appear, the latter having fed on and killed members of the crew, before introducing themselves. Klaus, suddenly appearing at the top of the stairs with a dead body in his arms and blood on his mouth, laughs with Rebekah about "leaving the best til last". In regards to introducing them, Rebekah retorts by calling him a beast as Klaus tosses the corpse down the stairs.
In the present, Elijah arrives in New Orleans in an attempt to find his brother and he heads into the bar Rousseau's, in which he strikes up conversation with the human barmaid. He tells her about his brother's paranoia that people are conspiring against him and asks if she knows of Jane-Anne Deveraux. Elijah, after finding out about Jane-Anne's execution, demands to know what she wanted with Niklaus from her sister; Sophie.
As Sophie tells her of Niklaus' predicament, Elijah soon meets Hayley and uses his tactile telepathy in order to show her memories of his human days. He shows her the night that Henrik died, how Klaus carried his body back to the village. He also shows her after their transition, he, Niklaus and their father, Mikael were in the woods when Klaus suddenly dropped, screaming in agony as he began to transform into a wolf, indicating he had recently made his first kill. Later, flashbacks show Mikael and Elijah tying Klaus to a wooden pole as their mother, Esther, casted a spell to suppress Klaus' werewolf side. Klaus quietly begged Elijah to help him, however Elijah followed his father's wishes.
Klaus is first seen in the present standing upon a balcony as Elijah appears behind him, telling him he has found out who is conspiring against him. As Klaus is told of Hayley's pregnancy, he is outraged, believing Hayley to have slept with somebody else and doesn't believe what they are saying is the truth. As he leaves, he snarls for them to kill Hayley and the baby. Elijah follows him outside in order to get him to change his mind. Elijah's words don't pacify him and he continues to deny the pregnancy and that it will not give him power, and that he isn't willing to be manipulated by the witches.
Klaus is then later seen with Marcel, observing the courtyard, the vampire's and loud music. He converses with Marcel over trivial matters, however begins to grow increasingly annoyed with the younger vampire when he calls New Orleans "his town". Klaus huffs that before he left 100 years ago, Marcel was a "pathetic little scrapper still trembling from the lashes of the whips" of those who brought him down as a child. Marcel knows he is jealous and snarls that it is his town, that he is the king. Klaus stands for afew moments, the music quietening down as people observe the scene, including Eiljah from afar. Klaus smirks before quickly turning and biting one of Marcel's closest vampires, infecting him with his bite. He says to Marcel that he broke one of his rules yet he is immortal and cannot die, walking away saying "who has the power now, friend?"
The witches have told Elijah that Klaus had until midnight to change his mind about the child and Hayley's life before they die - as Jane-Anne's spell linked Sophie and Hayley together. As Klaus is heavily drinking around a back lot in the quarter, he smashes a bottle upon the floor, knowing Elijah is behind him. Klaus tells him to stop harping on about the baby and Elijah vamp-speeds towards him, determined to knock some sense into him. The two begin scrapping and Klaus knocks Elijah off him before the latter returns, saying he will belt him like "their father used to", in order for him to regain his humanity. Klaus calls him pathetic and a "sentimental fool" as Elijah tries to mention family once more. Elijah walks off, leaving Klaus to ponder the events.
Klaus is later sitting upon a bench, seemingly having thought about things, when Elijah sits down next to him. Klaus solemnly reveals that the town was his home once and that he wants it back, that he wants to be king again. Elijah asks if that is all the child means to him before saying the child could change him, give him something he never believed he had; unconditional love of family. Klaus then looks at him and tells him to tell Sophie that they have a deal. The next day, Elijah is helping Hayley unpack things in their new house, which was co-incidentally their old house when they lived there and tells her he would always protect her. Klaus appears, taunting "noble Elijah, keeping his word". He then tells Elijah he healed Thierry, and that Marcel thinks he is on his side again.
Elijah and Klaus are talking in another room, taking sheets off their old belongings. Klaus says that they can destroy Marcel's army from the inside. Elijah asks about Rebekah. Klaus knows that Rebekah doesn't care and that he "shoved her in a box one too many times" and the elder brother says she will hopefully come around. Klaus, reaching down beside an object says he hopes Rebekah stays far away as there is a weakness in Rebekah that Marcel would exploit. Elijah asks what that is. Klaus simply looks at him and says "you" before quickly shoving a dagger into his chest. As Elijah desiccates, Klaus says family is a weakness and that if he is to win this war, he has to do it alone.
In House of the Rising Son, Klaus has stayed in New Orleans for three months. Klaus and Marcel are standing on the balcony of the Abattoir and Marcel is telling Klaus that they lure humans to his club and at midnight they feed on them, Klaus questions Marcel about what they do with the bodies and he reveals that they feed the vamp blood to avoid any suspicion. Thierry comes up to them and informs Marcel of that six of Nightwalkers has been killed in a bar.
Later at his house Rebekah has arrived, she demands to know what he has done to Elijah and he does not say but hints that he has daggerd Elijah. He asks Rebekah if she was the one that killed the 8 Nightwalkers, wich she admits to have done. Klaus brings up Marcel and his rules when Rebekah claims that he does not have anny friends. He gets a text and is about to leave whe Rebekah asks where he is going, he tells her is going to have drink with Marcel. Rebekah questions what part it has in his plan to undermind Marcel's empire and Klaus reveals that when friends drink they tell secret and he is hoping to learn what allows Marcel to contol the witches and take it for himself.
He finds Marcel at a bar looking at Camille. Marcel tells Klaus that two of the guests from the other night are dead and are now in transition (Josh and Tina). Klaus gets up and talks to Camille and he sets up a possible date between her and Marcel. Later Marcel brings him to a van with Josh and Tina inside. Marcel throws a coin and the one that pick it up gets to become a vampire and the other will die. Tina picks it up but Marcel kills her when she betrayed Josh. Klaus escorts Josh into a car.
At a bar Klaus is having a drink and Marcel comes in and is angry becuse he didn't tell him that Rebekah is back. Marcel asks him there is anything more that she needs to know, like if it was her that killed his 6 nightwalkers which he denies. Marcel then gets a call, saying there is a werewolf in town. Klaus returns home to find 3 dead and 1 living vampire at the house, becuse Hayley left the house. Klaus is furious with both Hayley and Rebekah and jells at them that the put his plan in peril, Rebakah defends herself by saying she was protecting Hayley and says that Klaus has done nothing to honor the deal that Elijah made for his child. He responds by saying he has done everything and tells Rebekah that since he came to town Marcel has not trusted him and has had his men ingest vervain, so when Marcel lost 6 nightwalkers he killed Josh ans Tina and he compeld Josh into becoming his spy as he had not been given any vervain yet. Then he compeld Cami into dating Marcel and to be his spy. He draggs Max into the house to drain him of vervain and compel him. Still angry with Hayley he demands to know what she was doing it Quarter in the first place. Hayley snaps and tells him that she was buying poison to kill the baby. Enraged by this Klaus grabbed Hayley by the throat and begins to choke her, showing that he cares about the child. Rebekah intervened and told Klaus that it is okay to care and to want something. Klaus sits down next to his sister and tells her that he gave Elijah to Marcel as a peace offering.
The next day he enters Hayley room to see if she took the poison or not. Hayley tells she didn't take the poison. Klaus asks her why didn't use it and she said it was becuse of that both her birth and adoptive parents abandond her. Hayley asks what happend between him and Marcel. Klaus replied by saying he made Marcel what he is and treated him like a son and after Mikael chased him and his siblings from New Orleans, they all believed that Marcel had been killed and they mourned him. Then after he returned he did not only find that Marcel had survived, but he had taken everything that his family built and made it his own. And now he is living in their home, sleeping in their beds and the letter M that he stamples everywhere is not for Marcel it is for Mikealson. Klaus also tells that he wants it back and if he has to push Marcel to get it, that is exacly what he will do.
In Tangled Up In Blue, Klaus sets the 3 dead vampires on fire and the next morning Hayley asks both him and Rebekah what the plan is to get Elijah back. Klaus say there is plan A: ask Marcel for Elijah back and then there is plan B: war. Klaus goes through with plan A and asks Marcel for Elijah back, but he says no and invites him to the party he is going to host.
He is later on the phone with Rebekah while Josh is draining Max of vervain. Rebekah tells Klaus that she is going to deal with Sophie and Katie the witch that rated out Hayley. Klaus walks to Josh noticing that he is not draining the vervain out of Max fast enough and drives a pitchfork through Max and compels Josh to do the same. Josh not knowing why he did it ask how Klaus made him do it and he explains how compulsion works. Rebekah calls him again and informs Klaus of that Katie is the girlfriend of Thierry, making him the key element in the plan.
Later Klaus and Rebekah were having a talk with Sophie asking her to do a tracking spell in order to find Elijah and Davina at the same time. They also ask her to play a part in their plan and have Katie use magic so Davina won't sense the locator spell. Klaus reveals to Sophie that Katie was the one that got he sister killed to motivate her.
Klaus has a talk with Marcel and convinces him that the witches a planing something and Marcel has Thierry bring some nightwalkers to do a rausting with the witches, all part of Klaus plan. Klaus later talks with Rebekah over the phone and tells her that he compeld Max to feed on Katie, wich made Thierry attack Max and kill him and that will leave Marcel with no choice but to punich him and Katie will try to save Thierry.
Later Klaus attends Marcel's party with Rebekah and he sees that Rebekah has invited Cami as a distraction and payback against Marcel. When Marco tells Marcel what Thierry had done, Klaus just watched on as Marcel furies talked to Thierry and then he sent Josh to bring Marcel the spell to make daylight rings, saying that they found it in Katie's store. This left Marcel even more angry and he sentenced Thierry to the Garden. As Marcel and his vampires are escorting Katie shows up as planed to save Thierry, givig Sophie time to cast a locator spell. While Katie attacked the vampires with her magic, she got close to kill Marcel until Klaus saved him by killing Katie.
Kaus and Marcel later have a talk involving Thierry. Marcel then thankfull for Klaus saving him will give him back Elijah. Marcel then asks how much Cami saw and Klaus tells him that she only saw a argument nothing that can't be fixed. Klaus walks into the bar and he sits down next to Cami and tells her that he needs her to give Marcel a second chance and compel her to do so.
He returns home to hear Rebekah say that they failed wich Klaus sade is not true and he reveals that he was the one that killed Katie and he knew that she would try to take out Marcel. He also reveals that he was only using Sophie as she and the other witches only wants to have Davina and he is going to take her for himself before anyone can.
Klaus goes to Hayley to tell her that Elijah will be returning soon and as he is about to leave Hayley stops him a tells him that she thinks the baby is a girl and Klaus leaves the room with a smile on his face.
InBloodletting, Klaus is at Marcel's Fight Night. Him and Elijah interrupt it to ask Marcel where Hayley is. Marcel doesn't know where she's at and tells Sabine to assist Klaus and Elijah. Sabine performs a spell and reveals that Hayley is in the bayou. Klaus and Elijah drive there together and search the bayou for any sign of Hayley.
Eventually, Klaus discovers Tyler is holding Hayley captive. Hayley fled into the woods. Soon after, Klaus and Tyler confront one another, argue and then battle. Tyler, no match for Klaus, is defeated with little difficulty. He did stab Klaus through the chest though.
Later on, Klaus is found at the cabin by Hayley and Elijah and the three get into a heated argument about family and the recent events that are unfolding. Klaus, not pleased by Elijah, bites him which will make Elijah weak. He returns to the house and is talking to Rebekah about the situation. Rebekah informs Klaus that he never actually understood why Elijah cared for him and Klaus admits that he's in the wrong.
In The River in Reverse, Klaus is having breakfast with Rebekah. He is first seen filling a glass with blood from a woman's arm and whilst doing so he asks rebekah if she has seen Marcel, intending to find out why he has been avoiding him and draw attention to Rebekah and Marcel's relationship. Klaus speaks to rebekah wondering why she is giving him a "devil stare", assuming it is because he bit Elijah. Rebekah answers saying that she is worried Klaus would bite her also if she were to voice her opinion, however Klaus states that he would never bite her and that his preferred method of punishment is a dagger.
Next, Cami is recording Klaus' memoirs on a typewriter as Klaus speaks. Klaus is ranting about his dissapointment in his siblings and he finds a mysterious drawing of Cami's; she mocks him by saying that it's a plot to destroy him and then a tattoo design.
Klaus then surprises Josh by turning up at a building where he is working on a car and says that he has the "role of a lifetime" for him. In a scene between Rebekah, Marcel and Josh, it is revealed that Klaus tried to compel Josh to steal a dagger from Marcel, however the compulsion didn't work because Davina removed the previous compulsion of klaus from him. Josh does not get the dagger for Klaus but does what Marcel asked him by telling Klaus that Marcel has it on him.
Klaus goes to visit Cami's uncle, the priest, in hopes of getting him to persuade Cami to leave New Orleans. Afterwards he goes to confront Marcel, unaware that Rebekah had schemed with Marcel to subdue him. Before the start of the fight Klaus throws a coin and states that whoever picks up the coin will get to live, but nobody picks up the coin and the fight begins. Klaus kills two vampires that attack him and cockily puts his arms out. The tables turn on Klaus because chains are wrapped around his arms and he is dragged and then beaten up to the point of being on his knees. Klaus then growls and displays his hybrid eyes. He breaks free of his chains and begins to attack and slaughter the vampires around him. This continues but Marcel stops the fight, then he picks up the coin and pleges his allegiance to Klaus; after Rebekah tells him it is the only way to stop him killing everyone. At the burning of the deceased vampires from the fight, Klaus and Marcel have a conversation in which Klaus makes it clear that he wants his home back and Marcel agrees.
Klaus later, feeling betrayed holds a dagger to Rebekah when she confronts him after the fight, but then lets her go upon Elijah's arrival and demand. Klaus then says to Elijah that maybe it should be him he daggers because he feels that Elijah will replace him as a father to his child. Rebekah comments that they do not abandon him, he drives them away. Klaus then, hurt, says that he has done nothing lately but co-operate and bow down to Elijah while Rebekah is with a man she shouldn't be with, who stole their home from them. He also says that it was them who let him down by not believing his intentions for his child were pure. Klaus leaves with tears down his face to go to his reclaimed home with Hayley, stating that the child is the only thing that matters to him.
"I never answered your question, if I’d ever thought about being human. Once. I was on a trek in the Andes, and a hummingbird flew up to me and just hovered there staring at me. Its tiny heart was pattering like a machine gun. And I thought, what a thing, you know, to have to work that hard every day just to stay alive, to be constantly on the verge of death, and how satisfying every day must be that it survived… And that was the only time I thought about being human."
—Klaus to Caroline about being human
While he was still a untriggered werewolf, Klaus had a complicated life. He was close with his half-brothers Elijah and Henrik and his half-sister Rebekah, whom he affectionately called "Bekah". However, he had a bad relationship with his overbearing father Mikael who was harder on him than on any of his siblings. Klaus even admitted to Rebekah that Mikael frightened him which made him constantly seek his approval without ever finding it. His mother Esther often tried to calm Mikael when he became angry with Klaus, but she never tried to stop him from humiliating her son. This led him to resent both his parents and possibly to be jealous of his siblings for having their approval. In the director's cut of the backdoor pilot of The Originals, Elijah pointed out that as a human, Klaus was so full of love.
Original Vampire/Werewolf Hybrid
Klaus is described as being sadistic, careless, paranoid, impulsive, emotional, short tempered, volatile, narcissistic, manipulative, jealous, obsessive and competitive. Klaus has little to no regard for human life in general, the opposite of his half-brother Elijah, who lives by a moral compass, has compassion and regard for human life and shows ability to feel guilt and remorse for his actions. Despite his negative traits, Klaus has shown to be very protective of his younger half-sister Rebekah, who stayed by his side for centuries, and he is not pure evil (he is just sadistic). Unbeknownst to any, Klaus was not the son of Mikael, but the son of a werewolf in another village which made Klaus both aggressive and angry. When he became a vampire, all these emotions were heightened and Klaus' temper became worse than ever. Years of humiliation at Mikael's hands and Esther's indifference, coupled with her rejection of him as her son, led Klaus to kill his own mother in revenge and for betraying him. After this, Klaus shut off his humanity to any but his family, killing any who crossed his path. Vengeful and power-hungry, he will stop at nothing to achieve his ends and remove those who stand in his way. However, Klaus does not believe that death is a punishment as seen when he denies Katherine death, instead keeping her alive so that she will suffer for having betrayed him. He will also place usefulness before pleasure and keeps people alive when it suits his needs. He has also shown a penchant for working with witches which was mentioned by Katherine in Know Thy Enemy. Klaus also has a sense of honor and will not go back on his word although, like his half-brother Elijah, he will always look for loopholes in the deals he makes. He has also shown a sadistic side notably when he deals with humans or vampires who have crossed him, such as Elena, Damon and Katherine. (His sadistic nature is sometimes mistaken for psychoticness). However, Klaus' hunger for power actually hides a deep fear of being alone which must stem from his step-father's treatment of him. He wants the hybrids so that he will not be the sole member of his race as Esther intended when she placed the curse on him. He also desires, beyond anything else, to be reunited with friends and family as shown by his desire to have Stefan, his one-time friend, and his family back at his side. He has shown to have a softer side when he is around Caroline, or a member of his family, but rarely shows it around other people. Caroline brings out Klaus' humanity. He also holds grudges against the people who try to kill him, or members of his family, and rarely lets it go. Klaus is self-preservation whenever he is in a situation where he could be killed permanently, he reveals information that keeps him from being killed, like when he told Elijah that he didn't bury their family at sea, or when he told Stefan and Damon he is the one who sired their bloodline. Klaus rarely gets made a fool out of and also doesn't like to be made a fool out of either. He is rarely caught off guard or by surprise. He is intelligent, calculating, thinks of contingencies, and he is always two steps ahead of his enemies. Klaus is not as forgiving as his half-brother Elijah; he rarely forgives any of his enemies. Despite him being the world's most powerful immortal being, he does not possess any arrogants, and he is not completely fearless, the only thing he is afraid of, is the white oak stake, because it is the only physical weapon, that can permanently kill him. Klaus has a sarcastic sense of humor, he is also sarcastic even towards members of his own family, despite his lust for power, Klaus still cares about the remaining members of his family. He does not like being lied to, or manipulated. He does not take being betrayed Very well, especially if it is from a member of his family, he is not tolerant of people who disappoint him in general, Klaus is ruthless towards his enemies, he rarely shows any of his enemies mercy.
During his time in New Orleans, Klaus has grown to genuinely care about his unborn child, and was deeply hurt when Elijah and Hayley falsely accused him of using he or she to sire more hybrids.
Klaus is an attractive figure. His height is 5'11. Klaus possesses curled light-brown hair and light blue eyes that contrasts with his pearl-white skin. As a vampire and a warrior (10th century), he is well-built. Klaus possesses a delicate and yet masculine face, possibly due to the fact that he was once a nobleman in the 15th century.
Klaus' clothing style is quite casual, usually seen wearing shirts, jeans and jackets, although he can also use a more classic and refined outfit if the situation requires it (ex: the ritual of the moonstone; the Original ball thrown by Esther). He uses accessories, such as leather bracelets or necklace as seen in some scenes at the beginning of Season 3.
Elijah, Klaus and Rebekah promised to stick together as one, always and forever when they became vampires. But their relationship became strained when Klaus turned his back on them. Later on, he fell for Caroline. She is a challenge for him and that's what he likes about her. He eventually fell in love with her and she knows this. They became close friends as he gained her trust. He will continue to wait for her when she is ready to choose him. Klaus has began to repair his relationship with Elijah whom is trying to bring his family back together as one.
Elijah is Klaus' older half-brother. As humans, they were close, engaging in friendly sword fights, however their relationship became strained due to both falling for the the same woman, Tatia. After transitioning into vampires, along with their sister, Rebekah, they made a pact to always stick by each other "Always and Forever". In 1492, their close relationship crumbled upon the arrival of the doppelgänger Katerina Petrova. Klaus wanted to use her blood to break the Hybrid Curse, but after her escape, Klaus was furious and blamed his brother. Although Elijah promised he would find her, their relationship never recovered as in 2010, Elijah planned to help the Salvatores and Elena Gilbert kill Klaus. After Klaus broke the curse, at Elijah's mercy, he revealed that he didn't kill their family and that their bodies were safe. Elijah saved his brother's life, however was neutralized in return. Their bitter relationship continued after Elijah was un-daggered by Damon Salvatore. However, the brothers became allies after their mother returned and were unsure of her intentions regarding their family. In the Season Three finale, Elijah bargained for his brother's body back and was clearly devastated by his 'death'. Throughout the trials and tribulations which threatened to rip their brotherly bond, they have recently begun mending their relationship and even though Klaus refused to grant Katherine freedom by Elijah's request, Elijah has stated he won't give up on finding Niklaus' redemption.
Rebekah is Klaus' younger half-sister. Out of all his siblings, he is closest to her, and very protective of her. Klaus cares very deeply for Rebekah, but he seems to have a lot difficulty showing her that it is true. They are loyal to each other. They have never left each other's side and stood by one another no matter what happened. After Klaus was "supposedly" killed by Alaric in The Departed, Rebekah was heartbroken over losing her older half-brother whom she loved and never left her. When she finds out in the Season Four premiere that he was still alive, their relationship started to completely and totally fall apart when he chose to save Caroline over his own sister. Rebekah confronted him about how she never stopped loving him through everything. It was always her that was there for him when Finn, Kol and Elijah weren't. She then realized that he truly doesn't love her when he told her they are no longer family, and disowned her. But later in the season, Klaus saves her when Kol nearly kills her with a White Oak Stake. Even when she hates him, Klaus shows that he still cares and loves her regardless of what has happened between them.
Klaus and Caroline's relationship has slowly been coming together ever since he saved her life on her birthday in Our Town. Klaus later developed an unrequited romantic interest in Caroline and invited her to his family's ball. At the ball, they danced and talked together and she soon discovered a soft side to Klaus. When she returned home that night, she found a hand-drawn picture of her and a horse, from Klaus. As the series progressed, Klaus fell for her even more because in his eyes, she's too smart to be seduced by him, she's beautiful, strong and full of light. When Klaus returned for her graduation, he told Caroline that he intends to be her last love, no matter how long it takes. He believes one day that she will choose him and let him show her the world.
Marcel is Klaus' best friend and former student. It's complicated, but they respect each other. There's definitely a history between them. Also, Marcel is very much in favor of embracing his true nature as a vampire and that’s something he learned from Klaus and something they certainly have in common. When Klaus returns to New Orleans after 100 years, he finds that Marcel has taken control of the city. Seeing that his former student has used everything he's taught him and achieved glory, Klaus wants what he has, forming a rivalry between the two. But Klaus still sees Marcel as his old friend. After Marcel attempted to bury Klaus, he surrendered New Orleans to him and despite their still unresolved differences, Klaus asked Marcel to rule side by side with him.

Enhanced Healing Factor - Being the Original Hybrid, Klaus can recover/heal/regenerate from any injury much quicker and more effectively than any original vampire, non-original vampire, werewolves, non-original hybrids and humans. He also seems to heal much more quickly when exposed to vervain or wood.
Super Durability - Being the Original Hybrid, Klaus can take far more trauma than any original vampires, non-original vampires, werewolves, non-original hybrids and humans, without much discomfort or injury. Vervain, Wolfsbane, Wood, and White Oak Ash Daggers do not weaken him, making him virtually indestructible.
Mind Compulsion - Being the Original Hybrid, Klaus can compel the minds of most sentient creatures: humans, non-original vampires and non-original hybrids. He cannot compel supernatural hunters due to them being immune to mental manipulation. It is unknown if he can or cannot compel witches or werewolves.
Immortality - Being the Original Hybrid, Klaus does not physically age. He is immune to all forms of illnesses, toxins or poisons. He does not need to eat, drink or breathe. He has eternal youthful beauty with perfect features and flawless smooth skin. He also possesses an almost eidetic memory and cunninng intelligence.
Tactile Telepathy - Being the Original Hybrid, Klaus is able to display his memories in other beings through touch.
Dream Manipulation- Being the Original Hybrid, Klaus can control dreams and subconscious. He can produce and modify dreams, bestow nightmares or lucid dreaming. Other effects of this ability is the distortion of reality and being able to trap someone in their dreams.
Emotional Control - Being the Original Hybrid, Klaus has a limited degree of control over his own emotions, allowing him to switch off his humanity, making killing easier.
Daytime Walking - Due to his werewolf heritage, Klaus is able to move around during the day without the use of a day walking ring.
Klaus' Sire Bond - Non-original Hybrids are all turned by Klaus from werewolves. In doing this, he has taken their pain of turning into a werewolf away. They, thus, feel obligated to serve Klaus because his blood created them and have limited free will, along with lack of control. They listen to Klaus as if they're his slaves.
Werewolf Bite Cure - Only Klaus' blood is the only cure for a werewolf/hybrid bite and is capable of healing a vampire from the bites of a non-original hybrid or werewolf. It heals an infected vampire with a similar effect to vampire blood on a human. This ability is unique to Klaus as no other non-original hybrid has been seen or mentioned using it. Klaus' blood is the only supernatural blood that can cure any disease
Transformation Control- Klaus has complete control of his transformation since he first transitioned from Original Vampire to werewolf to the Original Hybrid when he broke the curse. Elijah informs Klaus that he remained a wolf for 2 days, even when the sun was up. As seen with Klaus when he bit Katherine, a hybrid can transform partially, displaying their wolf eyes and teeth. It can be assumed that unlike non-original hybrids, as the Original Hybrid, Klaus has complete control and awareness of his actions, even in his werewolf form.
Werewolf Bite - Werewolf bites contain a poison which is fatal to vampires. As the Original Hybrid, Klaus' bites take effect quicker than a normal werewolf bite and a non-original hybrid bite.
Lycanthrope Enhancement - Being the Original Hybrid, Klaus can use his werewolf traits to further enhance his own powers and abilities.
Claws - Hybrids can grow claws from their nails, even when they are still in their human forms. It is unknown how sharp a hybrid's claws are, however when Klaus was still in Tyler's body, it was shown that a hybrid's claws is sharp enough to penetrate a hybrid's very durable skin and is able to rip another hybrid's heart out.
Procreation - Due to his werewolf heritage, Klaus has the ability to procreate.
Immunity to Silver - While Klaus can be hurt by silver physically, he appears to immediately heal from the wounds caused by it. Magic bonded to silver cannot affect Klaus due to his werewolf heritage.
Shapeshifting - Being the Original Hybrid, Klaus can turn into a werewolf at will.
Eidetic Memory - Being the Original Hybrid, Klaus possesses perfect recall and is unable to forget. His mind is often called a "vault" in which he store all his information permanently.
Fangs and Werewolf Eyes - Being the Original Hybrid, Klaus has two sets of fangs and his eyes are yellow.
Full Moon- Due to his werewolf heritage, Klaus' powers and abilities are at their peak during a full moon.
Master Swordsman - Even before Klaus became the Original Hybrid, he was a Master Swordsman, even though he rarely uses a sword, due to his supernatural powers and abilities, Klaus' swordsman skills have not decreased.
Combat Skills - Klaus has shown to be an expert fighter even when unarmed; When Marcel's army took him on, despite being overwhelmed to begin with, he was able to fight them, almost evenly and overpower most of them, through his fighting skills and Original Hybrid powers and abilities.
White Oak Stake - Is the only physical weapon that can permanently kill Klaus. It comes from an ancient White Oak Tree during the time of the genesis of The Original Family. It was at first thought that the stake used to kill Mikael was the last White Oak wood in existence, but it was soon discovered by Rebekah and Klaus that there was a sapling of the original tree to replace the old; the wood of which was used to build the Wickery Bridge, and later turned into stakes from the bridge sign, one of which was used to kill Finn. Some of these stakes were destroyed, but Esther used Alaric's Gilbert Ring to make the last one indestructible. This stake almost killed Klaus and later killed his brother Kol. However, he is now untouchable due to the fact that he sired Stefan and Damon's bloodline, along with most of their friends and if they kill him with it, they will die along with him. The stake is now in his possession.
Invitation - In order to enter any house owned by humans, they have to be invited in by a person that officially lives there or the person of entitlement. Once invited, the Original vampire. cannot be uninvited. If an Original vampire lives in a house, other vampires can enter freely and if a vampire is in the house without being invited in, it will become disoriented and will begin to suffocate.
Magic - As a supernatural entity, Klaus can be harmed or killed by a witch/warlock that can channel enough power. Considering his level of power however this would likely be very difficult to achieve. The most notable case would be in Bringing Out The Dead where he mentions that Esther can kill him. Her knowledge of the spell that created vampires and thus, ability to reverse it, could be the deciding factor in this. Minor spells have little effect. His resilience to magic was shown when Davina tried to hurt him and he was barely hurt by her power.
Desiccation - Like any Original vampires and non-original vampires, being completely drained of blood or the heart stopping will cause Klaus to desiccate, losing most of his strength and any ability to move. He will appear as a corpse and can only start functioning again once he feeds on blood. This process can be replicated artificially by a witch casting a desiccation spell. It's unknown if Klaus would desiccate if his heart was torn out. However, it seems that any Original's body is indestructible, therefore it is possible his heart cannot be extracted. It is possible that their heart will completely reform in their chest if extracted.
The Cure- The Cure will strip an Original vampires of their immortality, causing them to become humans/witches or in Klaus' case, a werewolf. Esther had a spell which would have cured them of their immortality.
Hunter's Curse - If an Original vampire kills a member of The Brotherhood of the Five, they will be tormented until they kill themselves or the hunter is replaced.
Vervain - Due to his vampiric heritage, vervain is toxic to a hybrid, however as the Original Hybrid, Klaus will only be burned by vervain, if his skin is exposed to it, he will heal very quickly from vervain wounds however.
Wolfsbane - Due to his werewolf heritage, wolfsbane is toxic to a hybrid, however, as the Original Hybrid, Klaus will only be burned by wolfsbane, if his skin is exposed to it, he will heal very quickly from wolfsbane wounds however.
Events Influenced By Klaus' Goal Of Breaking The Curse
Isobel's return to Mystic Falls (under compulsion of Klaus) and with the help of Maddox, retrieving the moonstone and capturing Katherine and Alaric. After Isobel's job was finished, she was compelled by Klaus to take off her necklace and burn to death in the sunlight. (The House Guest, Know Thy Enemy)
Gloria - She was a powerful, 116 year old witch and also the owner of Gloria's. Unlike vampires, Gloria was not immortal. Despite her charmingly good looks and forty-year old appearance, Gloria was the only witch ever known to discover a spell that could decrease the speed of human age. She was killed by Katherine.
Greta Martin - She was a witch, Jonas' daughter and Luka's sister. She was first mentioned in The House Guest by Luka. She was kept by Klaus and that is the reason Jonas and Luka joined Elijah in his quest to retrieve the Moonstone, but she was present with Maddox in Alaric´s apartment and she said she was happy to see Klaus (Alaric´s body). In the episode The Last Day, Greta mentioned she was never "lost" (abducted), which made clear that her intentions were always to help Klaus. She was killed by Damon.
Maddox - He was a warlock and was working with Klaus, aiding him with his magic. He was first seen in Know Thy Enemy. He was killed in The Last Day by Damon and Matt.
Hybrids - Hybrids are loyal to Klaus and will seek his acceptance because his blood created them.
Isobel Flemming - She was a vampire. Isobel was an expert researcher and Elena's mother. She managed to contact Klaus but when she found him, Klaus compelled her to gather information about Mystic Falls (Katherine, Elena, Stefan, Damon, Bonnie, etc.). He then compelled her to commit suicide by exposing herself to the sunlight when her job was done.
Stefan Salvatore- After Damon was bitten by a werewolf, Stefan seeked Klaus to find a cure. During the meeting, Klaus revealed the cure is his blood and Klaus manipulated Stefan to serve or else he would not give the cure. Klaus forced Stefan to drink countless bags of human blood as he wanted to awaken Stefan's ripper side. In the end, despite the attempts he had made in the second season to control his blood lust, Stefan gave in to the blood and killed a young girl at Klaus' order.
Mikael - Mikael was searching for Klaus and Rebekah in Gloria's and asked Stefan if he knew either of them and where they might be, but under Klaus' compulsion, Stefan said he had never seen them in his life.
Trevor - He was a vampire and a very close friend of Rose. He was killed by Elijah for betraying him by helping Katherine escape from Klaus during the 15th century.
Rose-Marie - She was a vampire and a very close friend of Trevor. She and Trevor tried to stay hidden from Klaus in the 15th century and had both been running from him ever since. Rose unintentionally helped to turn Katherine into a vampire. She then helped both Damon and Stefan to help protect Elena from Klaus and from being in danger. Rose was staked by Damon to keep her from suffering from a werewolf bite.
Elena Gilbert- Elena decided to surrender to Klaus to prevent any of her loved ones from suffering. During the sacrifice, she agreed to help Klaus to break the curse, with the hope that Elijah and Bonnie could destroy him but in the end, Elijah betrayed Elena and the others and escaped with Klaus.
Damon Salvatore - Damon wanted to protect Elena and Stefan from Klaus, causing him to work with Mason Lockwood and Katerina Petrova to destroy the Original Vampires once and for all.
Katerina Petrova - Klaus had her under his control, for the purpose of destroying the curse. Klaus found Katerina in England after being exiled from Bulgaria. Katerina saaid that Klaus was kind, gentle and caring with her but then she learned that she would have been used in a sacrifice and escaped with the moonstone.
Witches - Most witches despise Klaus, possibly due to him being a vampire. Klaus' mother has even broken the door to the Other Side to foil his plans. He has, however, had a few allies and friends that were witches.
Silas - Silas made Klaus think that he stabbed him in the back with the indestructible White Oak Stake and threatened Klaus to get The Cure for him.
In the books, Klaus is of unknown age, but is at least from the Bronze Age. He seems to have fought in every major war through time, most notably in Alexander the Great's army, in the Trojan War, and in the wars that led to the Roman Empire's downfall (on the Germanic side). He then decided to stick around the general area of Germany where, sometime in the 15th century. In the books, Klaus was the one who transformed Katherine into a vampire, in the TV series, it ended up being Rose who played the part, and Klaus and Katherine's back stories have been completely changed from the books. Klaus shows great strength and durability at all times of injury and other vampires feared law. For example: Klaus manipulates the mind of Katherine to inform the brothers Salvatore's that he is dead (Katherine kills Klaus centuries ago, because he is no longer useful). Klaus continually avoids Elena messages or visions to Bonnie and Stefan. A vampire must be invited by someone to enter your home, but Klaus enters Vicki's house and violently murdered her without one. Stefan and Damon fight against Klaus, but do not do any harm. In the books, when everyone tries to fight against Klaus, all of the weapons used against him fail. Klaus more or less kills Stefan, and nearly kills Damon as well, until an intervention from Elena's spirit, leading an army's worth of unquiet Civil War ghosts against him. The ghosts carry a screaming Klaus away, and his current whereabouts (and state of being) are unknown. It was later revealed that when he had attacked Meredith's grandfather before the books started, he had in fact been trying to capture Meredith and her twin brother Cristian. He failed to capture Meredith who became half-human, half-vampire as a result, but got Cristian who became a vampire himself.
Klaus is a German variation of "Nicholas ". From the Greek Νικολαος (Nikolaos) meaning "victory of the people". It's the name of a saint who is at the origin of Saint Claus legend.
Other spellings of the name Klaus are Claus, Claas, Claes, Clause, Klaas, Klaes, Klas, Klause.
Other spellings of the name Niklaus include Niklas, Niklaas, Nik, Nicholas, Nickolas, Nicolas, Niccolas, Nichalas, Nichelas, Nichele, Nichlas, Nichlos, Nichola, Nicholaas, Nicholaes, Nicholase, Nichole, Nicholias, Nicholl, Nichollas, Nicholus, Nioclas, Niocol, Nycholas, Nicholai, Nicholaus, Nichalaus, Nichalous, Nichaolas, Nichlaus, Nichloas, Nichlous, Nicholaos, Nicholous, Nicolaus, Nicholes, Nichols, Nickoles, Nicolls, Nicholis, Nicholos.
In the novels, the character of Klaus was partially based on Rutger Hauer's character (John Ryder) in the 1986 movie The Hitcher.
Klaus is the middle child.
John Ryder "The Hitcher": It is not clear where he came from, who he is or what his motivation is, but the one thing that is known is that his name is John Ryder. He has a sadistic drive for killing everyone and anyone he comes across. From what it seems, he is suicidal and he's on the look out for someone to do the task for him.
Given how far back his machinations have stretched, Klaus is more-or-less the main antagonist of the series overall, although he does not appear until the final third of Season 2.
Klaus is the only main antagonist to be in the main cast and consequentially, the only one to appear in the most episodes during one season (18). John Gilbert appeared in only the final 5 episodes during Season 1, Klaus himself only appeared formally in the last 4 episodes of Season 2, Esther only appeared in 3x08, 3x13, 3x14, 3x15, 3x19 and 3x20, and Silas appeared in 9 episodes of Season 4 overall, (4x13, 4x14, 4x15, 4x16, 4x17, 4x18, 4x19, 4x21, 4x22, 4x23), though 6 of them were as illusions of other characters and 2 were cameos, and he only appeared formally in 4x14, 4x19, 4x22 and 4x23.
Klaus is the Original with the most appearances so far (43).
Klaus is an openly HUGE Stelena shipper, alongside Caroline. In fact, Klaus is probably the biggest Stelena supporter next to Caroline on the show.
In the novels, Klaus seems to have fought in every major war through time (Alexander the Great's army, in the Trojan War and in the wars that led to the Roman Empire's downfall).
In the series, Katherine meets Klaus in England but in the books, Klaus remains in Germany for centuries where Katherine is turned into a vampire.
Klaus seriously affects the life of Katherine in the books and the series. In the books, Klaus controls the mind of Katherine and drives her insane, cruel, sadistic, cold, unstable, murderous etc. In the series, Katherine was not transformed by Klaus and was never his student, but she is damaged by the abandonment of her daughter, the death of her entire family and the terror of The Originals.
Klaus was said to be the oldest vampire in the history of time in Season 2, but it was revealed that Silas was actually the oldest vampire.
Klaus was revealed to not actually be a full vampire, but instead a half-vampire, half-werewolf hybrid.
Klaus takes the Originals resting place everywhere he goes, but keeps them well hidden at the same time.
In the books, Klaus is weak against the Spirits (Ghosts), because he can´t attack them. In the series, he is also somewhat weak against spirits since it's the power of the dead witches that Bonnie was using to destroy him.
In the books, Klaus was the one who killed Vicki whereas in the series, Vicki was turned into a vampire by Damon and then staked by Stefan.
He and Stefan are the only characters to have permanently killed another main character (Jenna and Vicki respectably).
In the novels, it was never established if Klaus needed a ring to walk in the sun.
In the novels, Klaus has his first and last battle against Elena, Stefan, Damon, Bonnie, Meredith, Matt and Caroline on the 31st of October. After that, the whereabouts of Klaus and his condition remain a mystery.
Klaus, Isobel, Rose and Katerina are the only characters thus far to have an episode named after them, with Klaus being the fourth and first male.
Klaus was introduced to Katherine Pierce on his birthday.
In the series, Niklaus shares similarities with Markus Corvinus of the Underworld film series.
Niklaus manages to break the curse using four women of different species: Greta (witch, although she was only needed to perform the spell), Jenna (vampire), Jules (werewolf) and Elena (doppelgänger).
In the series, he corrupted Stefan like he corrupted Katherine in the books.
Klaus is the first recurring role to be updated to series regular during their sophomore season Season 3.
Klaus, besides Damon Salvatore, has killed the most characters in the series, but most of Klaus' kills were off-screen.
Klaus is the only hybrid shown to drink any blood on-screen.
Klaus made the insinuation that Elena, Jenna and Jules are goddesses (Maiden, Mother and Crone) for the sacrifice.
In 1492, Klaus had all the elements to break the curse of the sun and the moon, but Katherine managed to escape with the moonstone.
In the books, Klaus was never human, but a pure blooded vampire and was very very old in age. In the show, he was once a potential warlock and far younger in age than in the books.
Rebekah assumed that Klaus' reasoning for making hybrids is due to his fear of being alone.
In Homecoming, Klaus said "I will kill you and every one you've ever met" to Stefan; this is how Katherine describes him when he's betrayed or angry. She tells this to Elena and Stefan in Katerina and Damon in The Last Day.
Klaus is a Beatles fan as he said in The Last Dance, claiming that they made the 60s bearable.
Of all the original vampires, Klaus can be considered the most vindictive and spiteful.
He was originally supposed to be killed at the end of the third season, but Julie Plec decided not to after she saw him acting.
Klaus is the first original vampire to become a regular.
It appears that Klaus daggers his siblings when they decide to abandon him. He daggered Rebekah for wanting to leave with Stefan. As Kol was a loose cannon, he probably wanted to explore the world for himself and was tired of dealing with Klaus, so Klaus hunted him down and daggered him too. The only sibling he didn't dagger was Finn, who was daggered by The Five, though Klaus decided not to remove the dagger.
Klaus seems to be a very talented artist. He even has a landscape painting hanging in the Hermitage museum and sometimes gives his paintings away to others for fun. His favorite thing to draw is Caroline.
Since Katherine was forced to take the cure, Klaus now has a chance to create more hybrids and the Petrova bloodline may continue.
Klaus has been portrayed by three actors, the 2nd character that has been played by more than one actor in the series, the 1st being Silas:
He is the only one shown to be protective of Rebekah.
Despite the fact that most people call Katherine with the Anglo version (Katherine) of her name, Klaus is the only one who solely calls her by her original name Katerina.
It is revealed in episode 4x01, Growing Pains that Klaus' body only survived the White Oak Stake because Alaric closed the coffin immediately after staking Klaus. In order for a fire to burn correctly, it needs access to oxygen. This is explained shortly by Klaus himself (Michael Trevino) "...When I assumed I'd be a pile of ash, but apparently fate and oxygen intervened..."
Caroline brings out Klaus' humanity and his playful side. He thinks that Caroline is beautiful, strong and full of light.
Klaus is the only original vampire to kill another original vampire, Mikael.
Klaus, Finn and Kol are the only Original Vampires with a known bloodline.
So far, Klaus has the largest known bloodline than any other Original Vampire.
The Casanova - Katerina (a little) and, most recently, Caroline
All Love is Unrequited - Caroline. Despite his attempts to woo her, and the fact that she knows he's in love with her, she is in love with Tyler and keeps refusing his advances. Still has chance to be averted, though is increasingly unlikely given the time he has left in Mystic Falls. See also Sympathy for the Devil .
And I Must Scream - Shared with family. However, instead of being daggered, Klaus must literally be chained and dessicated. When Alaric was turned into a vampire/vampire hunter, Klaus could do nothing to prevent Alaric from staking his dessicated body with the white oak stake .
(To Katherine in 1492) "Niklaus is the name my father gave me....Please, call me Klaus." -- Klaus
(To Elijah in 1492) "Love is a vampire's greatest weakness, and we are not weak, Elijah. We do not feel, and we do not care." -- Klaus
(To Katherine) "How could you? You betrayed me and fled England before I could even give you the details. But.. I did find your birthplace and I slaughtered your family. So I guess we`re cool." -- Klaus
(To Katherine) "Let`s just hope that Elena isn't as stupid as you were." -- Klaus
(To Damon) "I thought I remind you and your brother not to do anything you regret." -- The Last Day

(To Damon) "I thought I remind you and your brother not to do anything you regret." -- The Last Day
(To Elena) "You got me all nervous. I thought you had done something stupid." -- The Last Day
(To Damon) "I`ve heard about you. The crazy, impulsive vampire in love with his brother`s girl. I knew one of you would try to stop me. It was just a 50-50 guess on who." -- The Last Day
(To Stefan) "I heard about this one vampire, crazy bloke, always on and off the wagon for decades. When he was off, he was magnificent. 1917, he went into Monterrey and wiped out an entire migrant village. A true ripper. Sound familiar?" -- As I Lay Dying
(To Stefan) "There it is. You want to save your brother? How 'bout a decade long bender? And I have big plans for you when we leave this town." -- As I Lay Dying
(To Stefan): "I`m not mad, just curious. Rebekah seems to think you`re holding on to something. A piece of your old life. The thing is, she`s got flawless instincts, borderline supernatural. So I thought, I would check it out. See for myself what it is you`ve been hiding. Welcome back to Mystic Falls, Stefan."" -- Disturbing Behavior
(To Bonnie) "You put a rather large kink in my plans, sweetheart. The whole point of breaking the curse and becoming a hybrid was to make more hybrids. I haven`t been able to do that. Now my bet is, it has something to do with the fact that you`re still breathing.." -- The Reckoning
(To Bonnie) "If Bonnie`s successful, he`ll live through his transition. Go on, then. Go and fetch your grimoires and enchantments and what-not. I`ll hold on to Elena, for safe-keeping." -- The Reckoning
(To Elena) "It`s always nice to see a vampire in his true element. The species has become such a broody lot." -- The Reckoning
(To Stefan) "Now this is fascinating. I`ve never seen this before. The only thing stronger than your craving for blood is your love for this one girl." -- The Reckoning
(To Rebekah) "You know how much The Original Witch hated me. Do you honestly think I would do anything other than the opposite of what she says?" -- The Reckoning
(To Rebekah) "Yes, go tend the dinner. Leave the blades to the men, little sister."
(To Elena) "I`ll get straight to the point, love. People have been after me for a thousand year and I`m always one step ahead, so whatever it is you`re trying. Go for it, give it your best shot. You won`t succeed."
(To Tyler) "Human life is just a means to an end. Our means, to our end." -- The New Deal
(To Rebekah's dead body) "Here we are, Rebekah. Home sweet home. Only took a thousand years. And to think, I was counting on you being here with me. But that's all ruined now, isn't it? I'm so sorry, sister. We'll meet again one day." -- The New Deal
(To Caroline) "Do you really think that low of me?."
(To Caroline)"And I could let you, die, if that's what you want, if you really believe your existence has no meaning. I thought about it myself once or twice over the centuries, truth be told. But I'll let you in on a little secret, there's a whole world out there waiting for you, great cities and art and music, genuine beauty, and you can have all of it, you can have a thousand more birthdays. All you have to do is ask." -- Our Town
(To Damon)"Crazy or not. That kind of love never dies." -- Our Town
(To Esther): "Enough. All this talk is boring me. End this now, Mother, or I’ll send you back to Hell." -- All My Children
(To Bonnie): "There’s Jeremy, playing fetch with his new puppy. Oh, isn’t that just the most adorable thing you’ve ever seen?" -- The Murder of One
(To Bonnie): "Yeah, you’ll have to excuse the mess. Apparently Damon hurt her feelings. Go on, help him. Save the man who turned your mother into a vampire." -- The Murder of One
(To Stefan): "So, the fate of the entire vampire race depends on you finding a stake? And to get it we need you to pass out. Which means that I feel totally justified doing this."[breaks Alaric`s neck] ""There sleeping like a baby"" -- Heart of Darkness
(To Stefan): "That’s a little gratuitous, don’t you think, Stefan? I would have been more gentle."" -- Heart of Darkness
(To Caroline): "I don't have to prove anything, love. I am the alpha male. Come on. One dance. I won't bite."
(To Caroline): "You should be nicer to me. I'm leaving town tomorrow. I'd invite you to come with me, but we both know you're not ready to accept my offer. Perhaps one day, in a year or even a century, you'll turn up at my door and let me show you what the world has to offer."
(To Esther) "Your trap failed Mother. I still live and I will go on living and should your beloved spirits try to preserve you again I dare you to come after me. I will build an army so big no one will ever touch me. My survival will haunt you for eternity. You will never destroy me!" --Do Not Go Gentle
(To Jeremy) "Well, for starters, young Jeremy here could show some manners and invite me inside." --Before Sunset
(To Stefan and Damon) ""Hmm..poor lad. Loses one questionable father figure only to be replaced by the likes of the two of you." --Before Sunset
(To Damon) "Oh, I know all about my mother’s invulnerable little creation and that’s why I’m here. I’m leaving town, just need to pick up a few road trip necessities. Spare tire, flashlight, Doppelgänger." --Before Sunset
(To Stefan and Damon) "Just so we are clear. The sun sets in about eight hours. If we don’t succeed before then, Elena will be dead, I’ll be gone, and the rest of you will be left to fend for yourselves." --Before Sunset
(To Stefan, Damon, and Bonnie) "Before we all walk through these doors, let’s get on the same page, shall we? I was the one who created your vampire bloodline, therefore I am responsible for your lives and Tyler’s life, Caroline’s life, and of course, Abby’s life, should anything go wrong." --Before Sunset
(To Damon) "I’m not lying. But go ahead, call my bluff, let the teacher kill me. You’ll all be dead soon thereafter." --Before Sunset
(To Caroline): "It's okay, it's okay, it's me, you're safe. We'll go save Elena, you go straight home, you stay inside. Do you understand? Do you understand me?." --Before Sunset
(To Elena) "You know Stefan blames me for trying to tear him from his brother, but I think we both know who really came between them. You. That’s why you won’t choose. You know once you pick a Salvatore, you’ll destroy their bond." --Before Sunset
(To Elena) "Consider this me doing you a favor. Once you’re dead, you won’t have to choose. No broken hearts. Their family stays intact. But just between us girls, who would you have picked?" --Before Sunset
(To Caroline) "You're going to be fine, Caroline."
(To Caroline) "There's no point. I'm a lost cause. But you're strong, and you have a beautiful future ahead of you. And when you make it through this...Just tell my mother I left town like I was supposed to, ok?." --The Departed
(To Caroline) "Your mouth was all over me, I was an innocent victim!"
(To Tyler) "You went off to the Appalachians to break my sire bond. There you met a pack of werewolves, among them was a girl. She was gorgeous with the same animal instincts as you. Emotions ran high and ambitions ran low. In a moment of weakness the thick sexual tension became something much more real. And Caroline has no idea."
(To Rebekah) "I mean it’s pathetic really, isn’t it? How she continues to hand her heart to any man who shows her a hint of affection. You think she would have learned by now from the endless cycle of disappointment and deception."
(To Caroline) "I never answered your question; if I ever thought about being human. Once, I was on a trek in the Andes, and a hummingbird flew up to me. It just hovered there, staring at me, its tiny heart was pattering like a machine gun. And I thought, what a thing, you know, to have to work that hard every day just to stay alive. To be constantly on the verge of death and how satisfying every day must be that it survived. And that was the only time I thought about being human."
(To Stefan) ""Loneliness Stefan, that's why you and I memorialize our dead. There's the briefest of moments where we hold their life in our hands and then we rip it away and we're left with nothing. So gathering other peoples letters or writing their names on a wall is a reminder that we are left infinitely and utterly alone.""
(To Damon) "Twelve... that's a number. That's how many of my hybrids I slaughtered with my sword. Tree. That's how many days it took me to quell the urge to kill your brother, after he knowingly watched as I walked into a death trap. One that's the number of purposes you serve."
(To Jeremy) "You really think I care for an instant about my bloody hybrids. I want the cure so I could destroy it, I would have killed you all the second we dug it up. But now I'm just going to watch you burn instead.'"
(To Tyler) ""See, now I think you’re just telling me what I want to hear. I mean, you did call me pathetic earlier. And wouldn’t it be more pathetic of me to help now knowing that, hours ago, you announced your plan to kill me in a manner of which you’re still debating because you want it to have a certain amount of flair? Just asking."
(To Elijah) "I gave you that opportunity. And you sided against me. So if I run, it'll be to chase her. And as your only living brother, I will make it my cause that you never know a moment of happiness."
(To Rebekah) "You can stand idly by as poor April takes her final breath. You can ask, "Why does this always happen to innocent people? Where do the spirits go? Was there anything I could have done?" That is what it means to be human, sister. You give humanity too much credit."
(To Tyler) "Was it worth it?. To see her smile?. To make her dream night come true?. Was it worth it?. In the shared interest of giving Caroline the night of her dreams, I'm going to allow you five seconds before I rip the heart out of your chest. 5, 4, 3."
(Call phone to Caroline) "Caroline, I’m standing in one of my favorite places in the world surrounded by food, music, art, culture, and all I could think about is how much I want to show it to you. Maybe one day you’ll let me."
(To Camille about Marcel) "Abnormal psychology, well, perhaps you could help me diagnose my friend over here. He's been a little bit depressed. Can't get his mind of a girl. He tells me she's a queen fit for a king. I think he should cut his losses and move on. What's your professional opinion?. "
(To Hayley about Marcel) " I made Marcel everything that he is, I treated him like a son, and when my father chased me and my family from New Orleans a hundred years ago, we believed Marcel was killed. We each mourned him our own way. Yet when I returned, I found not only had he survived, he had thrived. "
(To Hayley about Marcel) " Now he is living in our home, he is sleeping in our beds. The letter "M" he stamps everywhere, i'ts not for "Marcel", it's for Mikaelson... I want it all back, and if I have to push him out to get it, then that's exactly what I'll do. "
(To Hayley) "Okay. Well, firstly, Marcel is not my mortal enemy—he is my friend, albeit one who is unaware that I'm trying to sabotage his hold over the supernatural community of the French Quarter, but a friend nonetheless. And secondly, I daggered Elijah in order to gain Marcel's trust. If I had known he would place my brother in the hands of a particularly nasty teenaged witch, I certainly would have weighed my options a bit differently. And thirdly, sister, please."

(To Marcel) " Still... You don't want the witches to get too bold, given that a witch's tip about a werewolf in town led to the disappearance of your nightwalkers. I'm sure you've considered the possibility that it could've been a trap. "
(To Davina) " If he remembers seeing you, he might come looking. If the witches learn of him, if they know you have a weakness, then poor Tim might end up as leverage in an awful scheme to control you. Again. "
(To Sophie) " We had a deal! You protect my unborn child, I dismantle Marcel's army. And whilst I've been busy fulfilling my part of the bargain, you allowed Hayley to be attacked and almost killed by a gaggle of lunatic witches. "
(To Agnes) " Enough! Please, enough! I don't care about witch politics. I don't care about your ridiculous little Harvest ritual. What I care about is this trinket... Undo its curse, or I'll show you things worse than death! "
(To Elijah) " You tend to give your word at the most inopportune times, brother. We've been doing things your way all day. Come on! Just one little snap and it's "Toodle-loo, Agnes." She deserves it! "
(To Elijah) " He was loyal in the beginning, but he grew insubordinate, turned my other hybrids against me. I couldn't have that, so I massacred the lot of them. Tyler ran like a coward before I could finish him off. "
(To Tyler) " Death offers more peace than you deserve. It's better to let you live. And each morning, you will wake knowing your wretched existence continues only by my will... Now go, and live the rest of your days knowing that you are nothing to me. "
(To Elijah) " And, of course, you assume it's true. I mean, why else would I show interest in my own flesh and blood? A heartbroken little crybaby points his finger at me, and my own brother falls in line, eager to believe it! How quickly you believe the worst, especially when it comes from her. "
(To Elijah) " My big brother, so, you doubt my intentions? Well, I can't say I'm surprised, standing next to the noble Elijah, how can I be anything but the lesser brother? A liar, a manipulator, a bastard. "
(To Rebekah) " Elijah and I had a bit of a row. Haha, Hayley's conspired to turn him against me. You know our brother was never one to resist a pretty face! So, one thing led to another, and I bit him, left them both stranded in the swamp. "
(To Rebekah) " Perhaps we will. After all, you know I'm capable of forgiving those who disappoint me! As soon as they've seen the error of their ways, and suffered for them. You'd do well to remember that. "
(To Rebekah) "Poppycock! I would never bite you. Elijah made some very offensive accusations about my intentions towards my child. He deserves a day or two of discomfort. Besides, you know my preferred method of punishment for your indiscretions is the dagger. "
(To Elijah and Rebekah) " Is that so? What have I done lately, other than cooperate? I bow down to you, brother, to make up for daggering you. For the greater good of our plan to reclaim our home. Looked the other way, sister. While you repeat the same cycle with Marcel, falling again for a man you shouldn't be with, while he controls the empire that we built! That he took! Now, I make no excuses for past sins. But in the one moment when you two could have chosen to stand by me - to believe in me - to believe my intentions for my own child were pure. You chose to stand against me, to side with my enemies. I wanted our home back. Now I have it. So I'm going to live there. And the two of you... you can stay here together... and rot. "
(To Hayley) " Because, Hayley, that child you carry is the only thing on this earth that matters to me. Now you can fight me on this, but you will lose. As will anyone else who tries to stop you getting in this car. "
