|“||They say the passage of time will heal all wounds, but the greater the loss, the deeper the cut and the more difficult the process to become whole again. The pain may fade, but scars serve as a reminder of our suffering and make the bearer all the more resolved never to be wounded again. So as time moves along we get lost in distractions, act out in frustration, react with aggression, give in to anger, and all the while we plot and plan as we wait to grow stronger, and before we know it, the time passes. We are healed. Ready to begin anew..||”|
Niklaus Mikaelson (a.k.a. Nik or Klaus) is the Original Hybrid and the central character of The Originals. He is the son of an unnamed werewolf and Esther, the maternal younger half-brother of a deceased unnamed older half-brother, Elijah, and Finn, the maternal older half-brother of Kol, Rebekah, and Henrik, the step-son of Mikael, with whom he had an extremely bad relationship before he later killed the latter. Little is known about his werewolf side of the family due to Mikael's onslaught. He is also the father of a yet to be born Hybrid Child with Hayley Marshall, and a distant relative of Cary.
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.
He was the main antagonist of Season 2, making his first appearance in Know Thy Enemy, in Alaric's body. Season 3 also started with him and Stefan Salvatore as being the main antagonists, but by the end of the season he had become an anti-hero, with Esther and Alaric Saltzman being the main antagonists. He is also one of the supporting antagonists of Season 4. He is now the protagonist and lead role in The Originals and is now living in New Orleans.
He is close friends with Caroline, whom he is in love with, best friends with Marcel, whom he works with in ruling New Orleans until Klaus discovered his treachery, for bringing Mikael to New Orleans. During the 1920's, Klaus formed a strong bond and brotherly relationship with Stefan Salvatore.
With Silas and Qetsiyah now deceased, Klaus is possibly the most powerful known supernatural creature in the series' universe. 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.
Mystic Falls, The Middle Ages, 10th Century
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.
stating that his aim has been improving, when he misses a shot. But, Mikael intervenes and scolds Elijah for encouraging his brother and snatches the bow from Niklaus stating that he wasn't man enough to hold a weapon. Niklaus tries to apologize, but Mikael sees him as a weakling and starts kicking him. Elijah tries to stop his father from hurting his brother but is scared off, by Mikeal stating that if Elijah intervened he would be next.
He was once beaten, half to death, as a boy, when his father's blades went missing. In the days following the incident, Rebekah was particularly kind to him which Klaus later realised meant that she had been the one to take it.
Niklaus and all his siblings used to play in the woods, when they were kids, showing they all loved each other dearly. He even stayed awake, to comfort a scared Rebekah by holding her hand, during a stormy night and giving her a wooden carved knight, which he made for his father stating that it will protect her, something that has been kept safely by Niklaus to this date as memento of his childhood.
Both Niklaus and Elijah were in love with Tatia, even though she had a child from another man out of wedlock. They both vied for her attention and even had arguements and blows over her, until their mother took her to stop the fight.They later found out that Tatia's blood was used for the The Immortality Spell placed on them.
Niklaus was once slogged by Mikael severely for taking his knife for carving chess pieces. When Elijah comes in and tries to stop his father from beating Niklaus to death, he gets pushed back. Then, Rebekah intervenes, by threatening to kill their father with a sword if he doesn't stop beating Niklaus. Mikael snatches the sword from Rebekah and leaves the place in rage.
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 becoming a Hybrid, Mikeal had Elijah help him 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 scattered and Niklaus stayed behind with Rebekah to bury Esther. Rebekah promised to never turn her back on him, like Esther did and so did Elijah. They swore to each other they would stay together always and forever.
Italy, 1114 A.D.
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.
New Orleans,18th Century to 20th Century
Having fled the Old World for unknown reasons, possibly Mikael arriving, 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 1720, Klaus and Elijah helped the Governor in building the New Orleans' first levees.
In 1820, Niklaus, Elijah, and Rebekah were living in New Orleans at the Governor's mansion; and were paying the governor in gold to keep quiet about the existence of vampires. One day the Governor threw a party for the Mikaelsons. Rebekah went up stairs with the Governor's son, who she wanted to turn. Rebekah went to Elijah with the Governor's son and asked if she could turn him, to which Elijah suggested it would be a unwise move to turn the Governor's son into a vampire. In that moment, Klaus took the Governor's son and threw him off the second story, killing him immediately. Klaus and his brother attended the funeral of the Governor's son, when Klaus sees a man whipping a child. Klaus saves the child; and decides to care for him. He names the child Marcellus.
In 1820, Klaus is seen challenging a man in a duel; but Klaus wins the duel. Elijah then becomes a little worried and asks Klaus if it is not enough, that he has slaughtered dozens in just these past several weeks. Klaus explains that a city littered with bodies will surely travel the oceans. Elijah asks his brother if he wants to bring their father upon them; but Klaus tells Elijah to relax. Klaus then explains that he has sent rumor that the bodies are a result of the witches seeking blood sacrifice for their rituals. Elijah is shocked because he is in love with a witch named Celeste; but Klaus isn't concerned. Elijah takes a revolver and shoots at Klaus, who groans with pain. Klaus sees that Elijah cares about Celeste and warns that they're rounding up the town's witches as they speak.
By 1835, Marcel and Rebekah spent practicing fencing, when Marcel was finally an adult, he could best her in a duel he attempted to make his move on her only to be stopped by Klaus. Despite pleading with Klaus to let him be with Rebekah, Klaus still shot him down and forbid him from pursuing her. However this did not stop Marcel from trying again and making out with Rebekah. They were abruptly torn apart physically by Klaus who decided to punish them by daggering Rebekah.
In 1887, Klaus undaggered Rebekah revealing he had left her daggered for 52 years. When she had asked to see Marcel, Klaus sadistically revealed that he gave Marcel an ultimatum. Either live a long human life with Rebekah and die or become a vampire, but stay away from Rebekah. He chose the latter, even walking into the room as proof, devastating Rebekah.
1900'sIn 1919, Klaus tried to make arrangements with werewolves in the city, so his rule could remain hidden. But their meeting is soon interrupted by the witch Alphonz Bellatunde Delgallo, also known as Papa Tunde, who demands to know how would it benefit for the witches. He demands a tribute as he thinks he is also the king in this city and brings them the head of the mayor who he has killed. Klaus doesn't like it and decides to find out who this enemy is. Klaus befriends him to find out his weaknesses so he could destroy him. With help of the Marcel he finds out that Papa Tunde channels two twin witches who always accompany him and kills them to get rid of this rival.
During this time, Klaus was very critical of Marcel and Rebekah's relationship, and they were determined to remove Klaus from their lives, and unbeknownst to Klaus, used a witch to call Mikael to New Orleans.
Six months after this, Klaus and Elijah attend a local club underneath the Opera Theater, and Klaus flirts briefly with Lana, the "Werewolf Queen" and owner, before he and Elijah contemplate the unification of New Orleans. Elijah tells him they worked together to build up the city, but it was originally Niklaus' vision.Sometime later whilst sharing a drink with Elijah, Klaus notices Marcel and Rebekah attempting to convincingly avoid each other, as he stands, Elijah tries to pull him down to refrain him from causing trouble.
Instead of condemning the pair, Klaus admits that as they move into the new era, attitudes must change. He toasts to Marcel and Rebekah, that they find joy in each other and that he has killed Rebekah's lovers to protect her from a broken heart if they have to move. However they are now home and he wants her to be happy.
After a morning with Lana, she proposes tickets for the Theater that night. Rebekah and Klaus are later seen in a box at the Theater, and Rebekah heads towards the lobby to find Marcel. As Klaus is left alone and the curtain about to lift, Mikael appears behind him, poking his back with the White Oak. Mikael taunts him over the word "father" and that his real father would be just as embarrassed before telling him his plan. After Klaus demands Mikael just kill him, he is proud of his achievements in creating the city, Mikael taunts death will come, however afterwards he will stay in New Orleans.
He will stay long enough to make sure everybody who remembers Klaus will be dead, and it would be as if he never even existed. As Klaus mulls this over, the curtains lift and Mikael announces he made some changes, sarcastically baiting he would love them. The audience applauses and laughs, compelled by Mikael as the curtain reveals Lana, impaled with a stake and Marcel is staked to a cross, barely conscious.
Klaus tries to save Marcel however he is thwarted by Mikael, and Rebekah intervenes only for Mikael to stab her and push her aside. Only when Elijah appears, they decide to run, that it was too late to save Marcel who Mikael was feeding on. As they flee, Klaus feeds Rebekah his blood to heal her as they hear Mikael approach. She is devastated at Marcel's apparent death and reveals it was her fault. Klaus denies this, instead apologizing to her, saying this was his fault, and as the Opera burns to the ground ahead of them with screams rippling from inside, that he thought they found a home. Elijah tells them to leave, that he will hold Mikael off. After hesitation, Klaus grabs Rebekah and the two leave New Orleans.
Chicago, 1920'sDuring 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.
Klaus made his return to Mystic Falls in 500 Years of Solitude. While Caroline is searching for Matt, she is reunited with Klaus. Klaus wanted to talk to Caroline, but she had no time to chat because Matt was buried alive. "I literally just whooshed at the sight of your face," she told him, using her vamp speed to get away from him. But of course he could keep up. He told her that Damon had let him know that Katherine had taken a tragic turn, so Caroline correctly assumed that he'd come to gloat. He also heard that Caroline and Tyler had broken up. She confirmed it was because Tyler had chosen his revenge fantasy against Klaus over her. Klaus wanted to know if he were to abandon his revenge against Katherine, would Caroline offer him the same choice as Tyler? Meaning, her. Caroline didn't want him to distract her when Matt's life was in danger, but Klaus assured her that he'd heard Matt's call for help and that Matt would be happy with his rescuer.
Caroline and Klaus continued their walk in the woods, and he told her he'd leave Mystic Falls without gloating over Katherine's corpse in return for one small thing. He admits the real reason he’s returned. He wanted a confession. About him. He said as soon as they were done there, he was going to leave and never come back. She'd never have to again cover their connection with hostility and revulsion or loathe the darkest parts of herself that care about him despite all that he's done. He just wanted her to be honest with him. Caroline reminded him of her being in college and her future plans did not involve him whatsoever. Hurt, Klaus understood; but Caroline said he didn't and that he's right about her covering up what she wants. If he was serious about walking away and never coming back, she'd be honest about what that was. After making his promise, Caroline kisses Klaus, further leading to a passionate moment in the woods between them.
In The Devil Inside, Klaus is mentioned when Caroline tells Katherine who is impersonating Elena that she kiss with Klaus and that she felt so good doing it that she ended up having sex with him. Katherine purposely makes that Tyler listen the conversation, he gets furious and Caroline follows him to talk to him, Tyler reminds her everything bad that Klaus made him as how to kill his mother and Jenna. He also appears in a flashback of Katherine's memories.
In Gone Girl, Klaus was mentioned by several characters.
The Originals Series
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, cast 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 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 daggered Elijah. He asks Rebekah if she was the one that killed the 8 Nightwalkers, which she admits to have done. Klaus brings up Marcel and his rules when Rebekah claims that he does not have any friends. He gets a text and is about to leave when 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 undermine Marcel's empire and Klaus reveals that when friends drink they tell secret and he is hoping to learn what allows Marcel to control 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 because 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, because Hayley left the house. Klaus is furious with both Hayley and Rebekah and yells at them that they put his plan in peril, Rebekah 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 compelled Josh into becoming his spy as he had not been given any vervain yet. Then he compelled Cami into dating Marcel and to be his spy. He drags 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 because of that both her birth and adoptive parents abandoned her. Hayley asks what happened 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 exactly 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.

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, giving 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.
Klaus and Marcel later have a talk involving Thierry. Marcel then thankful for Klaus saving him will give him back Elijah.

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 which Klaus said 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 points out that it is like trying to find a needle in a haystack. Klaus then brings up that due to the delay of Elijah's return he believes that Marcel is no longer in charge of the situation. And because of that he suspect that Davina's loyalty to Marcel has been strained, perhaps Davina is open to other alliances.

Klaus worried about the baby goes to her to make sure that she is okay and notice that she has completely healed and she says it's because she's a werewolf but Klaus she can't heal that fast. Rebekah tells him to leave her alone and realizes that the baby's vampire blood healed Hayley. Rebekah tells both of them that she has been in contact with Elijah and he has a plan. When Hayley gets up she almost collapses and Klaus catches her and brings her home.
That same night Klaus went to visit Camille. She invited him in and asked him if a vampire could have compelled Sean into killing nine people. Klaus then asks her to what end will learning what happened to her brother. Cami responded by saying that is the only reason she is on New Orleans . Klaus then tells it will bring her nothing but pain and it won't bring her brother back. He tells her the only way for her to find peace is for her to move on and forget. Cami understanding that he is going to compel her she asks him not to but he says it will only eat away at her and it will only put her in danger. Cami the says that he doesn't care about her he only wants her to be a good little spy. Klaus tells her he needs her loyalty but it is honor his brother the Cami asks what about her brother and says she needs to know who did it and make it right. Then Klaus compels her to move on and he promise her that he will find the one who harmed her brother and make them suffer.
In Sinners and Saints, Klaus grabs Sophie and brings her to his house accusing her of breaking their deal by letting Hayley be attacked by Witches/Warlocks. Sophie swears that she did not have anything to do with it and it was a faction of extremists that were behind it because of a vision Sabine had about the baby. Klaus asks what she saw and Sophie reveals that Sabine saw that the baby will bring destruction to all witches. Rebekah asks how extreme the faction is and brings up that Elijah is talking to Davina. Sophie the says that Davina will have much to say about the faction and Klaus tells her to tell them what she knows and she reveals that she did not like the strict way she was raised so she left to travel and play, but she returned eventually and she learned from her sister Jane-Anne that hey are going through with the Harvest a ritual preformed every 300 years in order for the witches to keep their power granted to them by their ancestors. They are interrupted in the story when Marcel calls Klaus to tell him that there has been a attack on Warlocks in the bayou and the injuries are consistent with that of a werewolf and he wants Klaus to come with him.
Later he is at the Big Auggie's Biker Bar and is on the phone with Rebekah and she tells him to stall Marcel from finding them. In order to do so Klaus asks Marcel some questions one being how he met Davina. Marcel reveals that it first started 8 months ago when he had a sexual relationship with Sophie and she to him about the harvest. The Klaus asked who Sophie turned to and Marcel reveals that Sophie turned to Kieran a priest, leader of the human faction and Cami's uncle. Kieran tried to convince the witch elders to not go through with the harvest, but to no success. In return for Kieran attempt to stop the harvest one of them put a Hex on Sean to distract him.
Later Klaus gets a call from Rebekah telling him that they went to the bayou and they were seen by a vampire who might be Marcel's informant Thomas and they lost him. Rebekah tells him to handle it and he says that he needs a distraction and Rebekah says that she is on her way. He then returns to Marcel and asks him what happened next. Marcel tells him that when the harvest was preformed the witches killed the chosen four, but before they could kill Davina Marcel showed up with his army and they stopped the ritual and when Marcel saw Davina being held by Warlock trying to get free Marcel saved her and Marcel tells Klaus that there was something in the way that she fight to know and Klaus respond by saying I do Marcellus reminding him of how he once saved Marcel as a child. Marcel continues to tell the story and when the other three girls had been killed Davina was given all of their power and that is what makes her so strong.
Rebekah later shows up to stall Marcel giving Klaus time to find Thomas and snapped his neck. He then returned inside and asked Rebekah where Marcel is and she asks him the same thing and they realize that Marcel was stalling them.
Klaus the waits at the Abattoir for Marcel and when he shows up he tells his son that his attempt to stall him was pathetic and he taught him better than that. Marcel responds by saying that Klaus taught to protect what is his and says you will not take Davina from me and Klaus says that the strong always take from the weak. Marcel responds by saying if he is so strong why did he run from New Orleans, this enraged Klaus and jumped from the balcony and punched Marcel in the face. He says that he can take Davina when ever he wants and when Marcel is about to attack he is but not by Klaus, by Elijah.
The brothers later return home and Elijah gets the family to tell them that the reason that they were lured back to New Orleans was not because of the war between witches and vampire, it is because of Davina. He says that Sophie and Jane-Anne lost everything when Jane-Anne's daughter Monique was killed in the harvest and Jane-Anne sacrificed herself to bring her daughter back, so it is about family. He also tells them that Sophie is the greatest threat against them because she is willing to give her life to kill Davina and bring Monique back to life.In Fruit of the Poisoned Tree, Klaus attempted to buy his brothers forgivenes by offering him a girl to feed on, but Elijah refused as forgivenes can't be bought. Then Klaus feed of the girl instead and left her body on the table. Afterwards the brothers began to ignore each other and sat down right in front of each other and read. Later Elijah ripps out a page from their mother's spell book and he informs Klaus and Rebekah of that he intends to use Davina to break the link between Hayley and Sophie and he also reveals that their deal with Sophie no longer stands. Klaus is then told by Elijah to accompany him to the church and stay guard so Elijah can have some time with Davina.

Kieran does what they agreed to and Klaus asked Agnes how to undo the curse she placed on Hayley. Agnes says it can't be reversed and his child will die. After Klaus learns that the link has been broken and his child is safe he tells Agnes that he is going to leave pieces of her at her family crypt, believing that it will send a fitting message; no one hurts his family. Then Elijah comes to the church and Klaus grabbs Agnes. Elijah tells him to let her go and in return he will give him his forgivenes. He does as his brother asks and after he says that it is much like him to spoil his fun Elijah attcks and kills Agnes.
Klaus later goes to Cami to tell her that he learned what happend to her brother and he reveals that Agnes is dead wich angers her becuse she did not ask him to make her part of revenge ans she swears that she will find a way to undo what he has done to her.

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 disappointment 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 pledges 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.In Reigning Pain in New Orleans, Klaus tries to gain trust of the quarter vampires by telling them that he has no intentions to create more hybrids which could harm them. To win their trust in this matter he allows them to kill off the werewolfs in the bayou so that they could be sure that he doesn't want to use his child this way. He is still upset with Rebekah and Elijah and is taking away their furniture and seeks comfort from Camille. He compels her to write his memoirs as he is upset with his siblings. Camille is mad at him as she knows that Klaus uses her as therapist and blames him from messing with her mind. Klaus tries to confirm his grip over the down and asks help from Marcel. He confesses to him all the things he did to win his home back. He also asks Marcel's help to move Davina closer to him as he would like to have such powerful weapon close by. Klaus then has meeting with the human leaders who want bribe for their silence as vampires rule this city. They also want to set rules on Klaus how they want him to behave to protect the locals. Klaus laughs at their face and says that they are lucky to have whatever he wants to leave them, because other way they have lost their usefulness.
Soon after meeting the council calls him to tell him that they don't accept his terms ant they attack him and Marcel as they are in the bar with other vampires. Many vampires die and Marcel blames Klaus for it as he failed to make peace with humans. Klaus and Marcel call a human council meeting where they take revenge for their vampires leaving only father Kieran alive. Klaus tries to make Marcel his friend again and tells him that te decision to take over the city was not entirely his own. He reveals to him that witches would have killed his unborn child if he would have refused their binding. He says that he will not be as bad father as was his and admits that he was jealous for Marcel having created this empire without him. Klaus realizes that he can rule the vampires, but he can't win them so he asks Marcel to rule with him as his equal.
Later he has to deal with Hayley who is angry with him because of his order to kill the werewolves. Klaus tells her that he did it partly to ensure Hayley's safety as it lessens threat to her from vampires who otherwise would like to kill her. Afterwards he meets Rebekah and Elijah who declined his rules and ended the werewolf hunt as they found out that their clan is connected to their mother. Rebakah says that they are trying to make amends for their recent behavior and they found the clan of his father's bloodline. Though they ask for his forgiveness he asks them why would he want it and leaves them. He went straight to father Kieran to ask him a favor to protect the werewolves in the bayou from himself and other vampires without they finding out about it. In return he is asked to set Camille free. He goes to her and tells her that he is a monster and shows him memories from his past, but Camille feels sorry for him not disgust. He says her that knowing about this world will only get her killed and then he compels her to leave New Orleans and forget everything she has learned about vampires. at the end of the episode he forgives Elijah and tells Elijah that when he and Rebakah are ready they are welcome to join him.
In The Casket Girls, Klaus calls Marcel as he discovers that Davina has escaped. As Elijah and Marcel are discussing how to get her back, Klaus has plan on his own. They go to the Casket Girls Festival and Klaus searching for Davina. Klaus finds Davina's friend Timothy and kidnaps him to lure Davina out. Then he calls Joshua to send his message to Davina. Davina comes to Klaus to get Tim, but she doesn't cooperate and attacks them ( Klaus, Marcel, Elijah) and overpowers them.
While Klaus is out, Davina leaves with Rebekah who wants to make her ally. As Davina showed him clearly that she is not on his side Klaus had back up plan. He had compelled Timothy before to poison Davina and Himself in case Davina doesn't return to him. As vampire blood is not curing the poison Rebekah calls Klaus to ask how to save her, but Klaus refuses to help her. Then Elijah and Marcel reveal to him their own plan which they made in case if Klaus goes to far. They had made a deal with a witch to protect Davina from dying which leaves Klaus still dealing with the witch problems. When Davina is safely returned to him Klaus takes her back without revenge on Marcel or Elijah for plotting against him. Later he meets Camille on the street and discovers that Davina has undone all the compulsion on her so she remembers everything.
In Après Moi, Le Déluge, at the beginning of the episode Klaus is first seen talking with Elijah while Davina is starting to lose control over her power. When the earthquake starts Klaus runs to Davina's room and discovers that she is coughing up dirt. As he realizes how great is Davina's power he soon begins to worry about the consequences and asks Marcel how to control her. Soon they find out that Davina's power is going to have four phases as she releases all the elements - earth, air, water and fire, making him worried about entire New Orleans. as they realize that the only way to stop Davina is to complete the harvest and is trying to make the Marcel agreeing with this.

They decide to make their mother Esther a New Orleans witch so they could channel her power and finish the harvest ritual. They bury their mother and take her power but something goes wrong and the girls who were killed for the harvest don't resurrect.
Marcel blames Klaus for Davina's death and this is making another barrier between their relationship. Klaus hugs him and tells him that he understands, because after he fled New Orleans he thought he was dead and it took him years before he could even speak his name. When he goes home he talks to Rebekah and asks her how did she find Davina so quickly and they share their regret over their failed plan to save her. When Rebekah realizes that this power could not have just vanish it leaves them with another problem to solve.In Dance Back from the Grave, we can see flashbacks from his time in New Orleans from 1919. He tried to make arrangements with werewolves in this city, so his rule could remain hidden. But their meeting is soon interrupt by witch Alphonz Bellatunde Delgallo also known as Papa Tunde, who demands to know how would it benefit for the witches. He demands a tribute as he thinks he is also the king in this city and brings them head of the mayor who he has killed. Klaus doesn't like it and decides to find out who this enemy is. Klaus befriends him to find out his weaknesses so he could destroy him. With help of the Marcel he finds out that Papa Tunde channels two twin wicthes who always accompany him and kills them to get rid of this rival. Present time he is in very good mood after his trip to Mystic Falls. He frees Thierry at Rebekah's request. Then he informs other vampires in the quarter about Davina's death and unsuccessful harvest. He tells them that since Davina is dead they can't any longer control the witches in the quarter. So he orders them to keep them busy with until their power fades. He puts Diego on charge and is disturbed when Marcel doesn't join them. He talks with Marcel about his attitude but they are interrupted by Diego who has found some dead vampires. As they find two dead vampires, who are not even staked he wants revenge and make them suffer. He tells Diego to gather all the vampires and found out who did this, but most of the vampires are too freaked out to help. He realizes that others are so afraid of this new threat he decides to find the answers himself. On his way to figure things out he meets Sophie and finds marks of a dark sacrificial magic.
Soon he gets the call from Camille who tells him that Papa Tunde is killing Marcel. He runs to save him and confronts Papa Tunde himself, who is having all Rebekah's power so he is stronger than Klaus. He almost takes Klaus down, but Elijah and Hayley break the spell so that he loses power over Rebekah and Klaus overpowers him. He finds Marcel dying and tells Camille to find him somebody to give him blood. Camille volunteers, much to Klaus's dislike, but he allows her to save him. As he thinks the war with the witches has just started he asks vampires in the quarter who will stay with him. Few leave, but most of them stay with him. He asks Sophie how could Papa Tunde return and finds out that it was because of the stolen Harvest power. As they learn that Harvest might not be over he has Marcel back, because he will side with him to get Davina back and end this witch war. They want to stop him from killing more vampires and are alert that the garden is dangerous place if Papa Tunde discovers it, but they are too late. All of them are dead, leaving Klaus facing a stronger enemy.
In Crescent City, Klaus is first seen in St Anne's church with Marcel to celebrate the reopening of it. They want Father Kieran to find out all that he can about the witches. Klaus gets a call from Diego who informs him that Papa Tunde is dead and they start to understand that their witch problems are only getting started. When he gets message from Camille he meets her at the church and she asks for his help with his uncle Kieran, who has been cursed like Sean. Klaus comforst her and tells her that his uncle is a good and loyal man. Camille asks his help and gives him Papa Tundes knife, which she was asked to stab into his heart, but she chooses Klaus over witches. Then Klaus and Camille are going to father Kieran and are bleeding him out so Klaus could compel him to overcome his dark curse. When this is done he goes to seek out the witch who hexed Kieran in the first place. He takes Monique for leverage to lure them out, but Marcel does not approve his plan. Marcel attecks him so Monique could escape and when Klaus fights him off he drops the blade. When he turnes around Sophie pushes this blade to his chest. Klaus is screaming in unbearable pain and then collapses, leaving him to the hand of the enemy.
In Long Way Back From Hell, Klaus is completely paralyzed by the blade inside of his heart. Genevieve removes the blade from his heart and Klaus awakens in a weak state. He asks Genevieve why she is so kind to him and she says he never did anything to her and she can't help but pity him in his current state. She gives Klaus a brew made with magic and he drinks it willingly and Genevieve reveals that she will show him his sister's betrayal and that is how she will have her revenge agains Rebekah. She shows him how Marcel and Rebekah snuck around behind his back and he already was aware of this and tells her if it's part of her plan to turn him against Rebekah it is ineffective. Genevieve says that is in not even close to their full sum of their betrayal.
Genevieve later revealed that Klaus' fear of Rebekah and Marcel's love had led to them conspiring to get rid of him. He is shown that Rebekah had manipulated Genevieve into summoning Mikael. Klaus is greatly affected by this and screams to Genevieve that he has had enough of her lies. Genevieve says that he must have known that Rebekah was responsible for calling Mikael, or atleast suspected and Klaus refuses to believe that Rebekah had taken everything he had accomplice away from him. Genevieve responds by saying that when they are done he will realize how wrong he is.
Genevieve shows him more proof of what Rebekah did and this time he sees when Genevieve cast the spell that called on Mikael with his sister and Marcel present. During the ritual he sees Mikael's blade that went missing when Klaus was a boy and Mikeal beat him half to death because he believed that he had stolen it and he should have known that Rebekah had taken it as she was so kind to him the weeks after the beating. After the vision has ended he knows the truth and screams out Rebekah's name in anger. Genevieve also shows him how Rebekah killed her.
Genevieve apologizes for what she did and says it was necessary for him to see so he can take his and her revenge. She offers him her wrist so he can regain his strength and he accepts it. She then releases him and gives him Papa Tunde's Blade. Klaus speeds of and begins to search for Rebekah. When he finds her she claims that it isn't true and he wants to believe her, but her face tells a different story and she begins to run.
Rebekah soon stops and Klaus comes down the stairs and reveals that he is no longer going to dagger her, he will use the blade on her and he describes what it's effects are, she tells him to do it. Klaus says that he is disappointed that she is not begging for mercy and forgiveness. Rebekah responds by saying that it won't do her any good and when Klaus asks how her father would look at her now she attacked him and he threw her through a wall. Rebekah grabbed a metal bar and began to hit him with it but he easily defeated her and had her on her back. Marcel then came speeding in and Klaus threw him into a wall and was happy that he could kill him now. He tells Marcel that he will make Rebekah watch Marcel die and Rebekah claims that it was her idea to call Mikeal and he turns to her and is about to stab her with the blade, but Elijah arrives and turns the blade on him and he is once again under the effects of the blade.
In Le Grand Guignol, Elijah removes the blade from Klaus' heart and asks Cami to look over him and slowly feed him her vervain laced blood, so he will recover slowly. When Cami asks him how he can hate his sister and he reveals that she has done something no one has done in over in a 1000 years; ripped his heart out. He begins to tell her that he allowed Marcel and Rebekah to be together and now realizes that he was a fool for not seeing their treachery, as they brought Mikael to town. Cami then assumes that he is consumed by revenge he will not achieve. Klaus responds to this by saying that he is not so sure because if they are going to run from him they will need a clocking spell and for that they need a witch.
Later, Klaus tries to get up but he is still weak and Cami stops him from doing so. After Cami makes a joke about him he tells Cami more of the story and reveals his relationship with Lana and it led to him geting tickets to the oprah. Cami then says she is not supriced that he likes oprah and he respond by saying that he has always had a softspot for the Le Guignol and says it reminds him of what happened in 1919.
When he pours himself a drink, Cami then enters the room and when she mentions Elijah's name Klaus tells her not speak with him of Elijah. Cami says that Elijah loves him and he agrees with her, saying Elijah proves time and again, even when Mikael enlisted Elijah to kill him. Klaus tells Cami that Mikael came to Elijah and wanted him to help Mikael to kill Klaus. Cami then interrupted him by asking him why he says kill when he is imortal and can't be killd and Klaus reveals that he can be killed and Mikeal had the one thing that could kill them; the White Oak Stake.
He continues to tell the story and tells Cami that Elijah refused Mikaels offer and said he would always stand by his brother and as a reward Mikael stabbed him with a piece of wood. Klaus says that Elijah often felt guilt for not stopping Mikael and Klaus would tell him not to blame himself. Klaus then received a text saying that Rebekah and Marcel have been seen in town. He then breaks a statue and pools out a stake. Cami asks what it is and he reveals that it is his own White Oak Stake.
Klaus is later feeding on a guy and Cami comes out to ask him what he is doing and he reveals that he is going to kill Rebekah. Cami then tells him not to kill his sister because if he does he will be filled with guilt and he won't survive it. Klaus responds by saying that he almost didn't survive Rebekah bringing Mikael down on him. Cami then tells him not hunt and terrorize Rebekah and Marcel, like he was terrorize, because if he does it he will become his father. Klaus then says he has been called many shades of monster but that was new and he says that Mikeal was the monster that monsters was afraid of. He then grabbed her to show he something.He brought her to the location of the oprah that burned down in 1919 and reveals that it was the work of Mikael. He tells her how Mikeal sat behind him with his stake aimed for his heart and when Klaus said that if Mikael killed him he would fall proud of what he had achieved. Mikael then agreed with what he said and revealed that after he killed him, he would kill everyone that remembers his name. Then as the show started it showed that Mikael had compeled the audience to applaud to what they where seeing; Lana impaled on the scene and Marcel chained to a x. Klaus reveals that he tried to save Marcel but Mikael stopped him and Rebekah intervened and Klaus says he believed that she was trying to save him all those years and now realizes that it was Marcel she tried to save. He continues to tell Cami the story and Elijah came to help them and together they ran and as they fled Mikeal burned the oprah to the ground along with Marcel they assumed. He says he lived but all that they built died as did the last shred of him that felt human and says that is what Mikael took from him that night. Klaus then assured Cami of that he was not going to terrorize Rebekah and Marcel for centuries, nor will he torment, humiliate or dehumanice them, he will just end them. Klaus then speeds away before Cami can respond.
Klaus enters the cemetary and he screams for Rebekah much like Mikeal screamed for him when they where leaving the city. He found his sister with Elijah and he told him to get away from Rebekah becuse she is his. He then puts his Hybrid face on and Elijah and Rebekah did the same.
In Farewell to Storyville, he is the cemetery with Elijah and Rebekah. He holds a hearing for Rebekah and she confesses what she did in 1919. He shows anger and goes after her when he possibly can. Elijah defends Rebekah and tells him what Mikael also did to them besides Klaus. Klaus stabs Elijah with the blade and then goes after Rebekah. He confronts her again and she tells him the truth. He shows sadness and stabs Rebekah with the White Oak Stake. Revealing that he missed her heart, he asks her what she wants. She tells him she wants what she always has: a family and a home, and he lets her leave New Orleans and live her life. He shows great sadness at her leaving though.
In Moon Over Bourbon Street, after a month, he and Genevieve have become lovers. He is shown not really be taking an interest in what's happening with the factions. He goes to the party and talks to Jackson. He tells Jackson about his mother and his biological father, saying that the ring could be the key to letting the werewolves not having to transform during the full moon. Elijah tells him to sign the document that brings peace to the factions and he does. He later smiles and it shows that the painting he drew has a full moon looking over New Orleans.
In The Big Uneasy,
- "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
Klaus is continuously 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 and physically/mentally abuses. 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 often seen as psychotic). 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. 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 people in general. Despite him being the world's most powerful immortal being, often displaying arrogance to mask his fear of being alone, he is not completely fearless. He is afraid of the White Oak Stake, because it is the only physical weapon that can permanently kill him. Klaus has a sarcastic sense of humor and 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 and brutal towards his enemies, and 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 her to sire more hybrids. Although, he does still maintain a twisted sense of humor about his child as he once referred to his child as "that" when discussion how to keep it and Hayley safe from Marcel. Klaus is also shown to be more mellow as he was shown to genuinely regret daggering Elijah and went out of his way to show how sorry he was, even going as far as to spare Agnes for trying to kill his unborn child just so Elijah could keep his word. It is possible that being in his former home, with his family, has caused his humanity to show more.

Changes from the Books
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.
