Niklaus Mikaelson

Niklaus Mikaelson (Elder Futhark: ᚾᛁᚲᛚᚨᚢᛋ ᛗᛁᚲᚨᛖᛚᛋᛟᚾ) was the main protagonist (and sometimes antagonist/anti-hero) of . He was a former main character, antagonist/anti-hero of . Klaus was an Original vampire and a werewolf, making him the Original Hybrid.
Klaus was the biological son of Ansel and Esther Mikaelson, step-son of Mikael, nephew of Dahlia, maternal younger half-brother of Freya, Finn, Elijah, maternal older half-brother of Kol, Rebekah and Henrik Mikaelson and uncle of an unnamed and unborn nephew. Klaus was also the father of Hope Mikaelson, whose mother is Hayley Marshall-Kenner and as well as the adopted father of Marcel Gerard - an orphan boy he rescued. 
Klaus was first mentioned in the second season of in Rose, during a conversation between Rose and Stefan Salvatore. Rose warns Stefan about the Original Vampires which led to Elena Gilbert believing Klaus was the oldest vampire in history. Elijah later mentions that Klaus is a recluse and trusts very few people, usually only in 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 species of werewolf-vampire hybrids.
In 1492, he finally got the 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 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, who had escaped him and stolen his moonstone. However, it should also be noted that he was also on the run from his step-father, Mikael, as Klaus had an abusive childhood.
Besides his family, during the 1920's, Klaus formed a strong bond and brotherly relationship with Stefan. He then met with the vampire, Caroline Forbes, and starts to care about her, eventually falling in love with her and tried to win her love, and after a long time they were friends. In New Orleans, he had a father/son bond relationship with Marcel whom he works with in ruling New Orleans until Klaus discovered his treachery for bringing Mikael to New Orleans. They reformed their friendship when Marcel saved his daughter and they worked together to bring down their enemies. He also cared for the bartender Camille O'Connell, with whom he had fallen in love before her death.
Klaus was primarily a member of the Mikaelson Family, and a member of an unnamed Family of Werewolves. He was connected to the Labonair Family, a royal werewolf family via his daughter, and a member of the North East Atlantic Pack as well as an unnamed Witch Family.

|-|1114 A.D.=
===Italy===
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 Daggers 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.

===England, 1492===
Klaus was an English nobleman during the late 15th century when he met Katerina Petrova, the second 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.

It was mentioned by Freya in Save My Soul, that the Mikaelson siblings resided in Copenhagen in the 1500s.

They found him in a tavern where he drank and feasted on humans carelessly. Despite their warnings of Mikael's coming, he refused to flee. When Klaus and Elijah insisted, Kol attempted to resist them but was subdued by Elijah as Klaus pulled out one of the white oak ash daggers and successfully neutralized Kol.
===New Orleans, 1700s===
Having fled the Old World, escaping Mikael , Klaus, along with Rebekah, and Elijah, and their daggered brothers sailed across the Atlantic ocean to the new world, their once childhood land; 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.

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.

==Personality==
<tabber>
|-|Untriggered Werewolf-Witch Hybrid=
While he was still an untriggered Werewolf-Witch hybrid, Klaus had a complicated life. He was close with his half-sister Rebekah, whom he affectionately called "Bekah", and with his half-brothers Elijah and Henrik. He also had a close relationship with his half-brother, Kol, but he did not get along at all with his half-brother, Finn, since childhood. However, he had a bad relationship with his overbearing step-father Mikael who was harder on him than any of his siblings. He was a victim of his step-father's physical and verbal abuse since childhood. 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 or from physically/mentally abusing her son. Also as an untriggered werewolf, Klaus had the aggressive behavior of one, but he could not act on it due to his mother making him wear a magical necklace, created to weaken his strength and thus leaving him vulnerable to Mikael's abuse. These following reasons led him to resent both his parents and possibly to be jealous of his maternal half-siblings for having their approval. In the director's cut of the backdoor pilot of The Originals, Elijah pointed out that as an untriggered werewolf, Klaus was so full of love and life, and that all he ever wanted was to be loved in return, especially by his step-father. This belief that no one loved him and that he was doomed to be alone forever was the main factor that changed Klaus' personality.
|-|Original Vampire-Original Hybrid=
</tabber>
==Attitude Toward Humans==
Based on what has been seen throughout both The Originals and , like Katerina Petrova, Klaus has no regard for human life. However, like Stefan Salvatore, Klaus has been known to keep memoranda of his kills.
In The Originals, upon learning of his unborn child, Klaus was willing to allow the witches to kill his unborn child and Hayley to show that he will not be given an ultimatum. Klaus, however, realized what the child could do to his life and saved them, suggesting that he cares about his family. He is shown to kill humans if it suits to his advantage or for feeding. However, he is shown to care for some humans, such as Kieran O'Connell, someone he respected; prior to his death, and Camille O'Connell, his trusted therapist, friend, and a woman he was in love with; prior to her death.
==Physical Appearance==
Klaus is an attractive man. His height is 5'11 (1.80 cm). Klaus possesses curled dirty-blond hair and dark blue eyes that contrasts with his pearl-white skin. His physical appearance is that of a man between 19-21, despite being over 1000 years old. As a vampire and a warrior (from the 10th century), he is well-built. Klaus possesses a delicate and yet masculine face, possibly due to the fact that he was a nobleman between the 11th and the 18th centurys.
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 necklaces as seen in most of his scenes on both shows. 
==Powers and Abilities==
==Weaknesses==
Klaus has some of the typical weaknesses of an Original Vampire and a Werewolf.
==Relationships==
===Elijah Mikaelson===
 
Elijah is Klaus' maternal older half-brother. As humans, they were close, engaging in friendly sword fights, however their relationship became strained due to both falling for 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 half-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 half-brother's life, however was neutralized in return. Their bitter relationship continued after Elijah was un-daggered by Damon Salvatore. However, the half-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 half-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 Klaus' redemption.
Unfortunately, Klaus' relationship with Elijah takes a turn for the worst when Elijah chose to believe Tyler's lies over him, that he is (supposedly) aware that his child's blood can make hybrids, and he plans to use his child's blood once she is born to make an army of hybrids, to take over New Orleans, Elijah falsely accused him of only caring about his unborn child, so he could use her to sire more hybrids, Klaus became hurt/enraged by the accusation, he violently bit Elijah in retaliation, their relationship became damaged after this. Klaus eventually forgave Elijah, when he apologized to Klaus for his accusation. Despite the fact that their relationship is now repaired, Klaus is barely on speaking terms with Elijah.
Unfortunately, their relationship becomes worse than ever, when Elijah daggered Klaus and allowed Hayley to try and take Hope away from him, in retaliation Klaus kills his half-brother's girlfriend Gia, and daggered Elijah with Papa Tunde's Blade, their relationship becomes estranged/broken after this, as they both want nothing to do with each other any more.
They reconcile by the end of the third season after allying together to stop the Trinity.
===Rebekah Mikaelson===
Rebekah is Klaus' maternal younger half-sister. Out of all his half-siblings, he is closest to her, and very protective of her.

Before she left New Orleans, thus separating, they had 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 half-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. After Klaus is again the King of New Orleans, she begins to form her own army and so to defeat Klaus and Marcel, since she tired of always being used by them. Nevertheless, Rebekah has tried to protect the daughter of Klaus at all costs. When discovering that it was Rebekah who brought their father to New Orleans, he decided to get revenge and wanted answers. She admitted that she wanted him dead as he robbed her of love and happiness. Klaus chooses not to kill Rebekah, but he exiles her from New Orleans permanently, possibly Klaus sees killing Rebekah too merciful; he indirectly threatens to kill Rebekah with the White Oak Stake, if she ever returns to New Orleans. Klaus decided to entrust the safety of her daughter to Rebekah, she returned to New Orleans to take Hope with her and care for her.
===Kol Mikaelson===
Kol is Klaus' maternal younger half-brother. Kol and Klaus both have a short temper. It is known that Klaus daggered Kol over a century ago. Kol and Klaus seem to argue every time they talk to each other, Kol even joked to Klaus about his dagger threats showing he was not over being daggered for a century. Even though he had been daggered for a century, he quickly got with times as he was seeing playing a video game perfectly. Klaus and Kol both like to drink together and have brotherly bond. Klaus cares deeply for Kol as he was rushing to his body when the Mystic Falls Gang daggered Kol. Kol seems to ruin many of Klaus plans like finding the cure for vampirism, by killing Shane and the newly turned vampires. In Every Mother's Son Finn reveals to his brothers that Kol is alive, and Klaus expresses disbelief that Kol would have gone along with Esther, stating that the only thing Kol listens to is his ego, but Finn confirmed Kol's supposed loyalty, saying that their mother's proposition had brought even the wildest of Mikaelsons onto her side. Kol later switches loyalties over to Klaus and Elijah. Klaus and Kol have been seen getting along at time since then, and fighting at others. They seem to banter often and in good fun. Klaus was furious with Kol for hiding where he hid Rebekah, and threw him to hungry vampires in his anger. But Klaus forgave him, when Kol was cursed by Finn. After all, everything Kol has ever wanted was his family to care about him. This wish came true when Kol died because of the curse. Klaus was there on his side, together with Rebekah and Elijah. Before Kol died he wanted Davina to leave him alone, but his three siblings came and Klaus said that Kol can't just flee from "Always and Forever". He died in their arms, as a part of the family. When Kol was brought back, Klaus hugged him even though Kol protected Davina who Klaus wanted to kill.
===Hope Mikaelson===
Hope is Klaus' only daughter and child with Hayley. In the beginning Klaus wasn't happy with the arrival of his baby, then with time he started to change his mind and began to worry about her safety. He looked happy when Hayley told him that the baby would be a girl, then he began to fight for her protection against his enemies. Now he loves her more than anything and in order to protect her from the people that are trying to kill her, he and Hayley decided it was best to send her away. She was given to Rebekah, who would keep her safe. Klaus was reunited with Hope when her safety was compromised. Hope is now living at home with her parents. The supernatural community is now aware of her existence.
Hope and Klaus' bond remains strong during the rest of the series until they were seperated due to Klaus sacrificing himself to save his family. Klaus feared that Hope would reject him upon being saved from Marcel's captivity. But, apart from some bad things he's done, Hope knows what Klaus is and isn't afraid of him. Hope's memory of Klaus was kept alive because of her mother telling Hope about her father such as his loyalty to his family, his love for her and his interests that she now shares with him.

Klaus shared stories from his long life, Hope showed him her magic when she healed a butterfly and they painted together. She knows how strong he is and, because of that, she believes he can keep bad things away.
Once he promised that nothing was going to harm her, Hope hugged him. Despite their time apart Hope calls Klaus 'Dad', showing that their bond is still strong.

However due to being supernaturally loyal to Klaus. Tyler was forced to do things he did not wish to do, such as when Klaus made Tyler bite Caroline. After losing his friends and his girlfriend, Tyler vowed to break the sirebond so he would no longer hurt his friends, even if that meant breaking every single bone in his body a hundred times. Klaus was unaware that Tyler started a coup d'etat against him by freeing the other hybrids and claiming the title of the Alpha of the Hybrid Pack. However Hayley who had helped Tyler with this task, had told Klaus, which resulted the massacre of the whole pack excluding Tyler. This wasn't enough to satisfy Klaus' anger, therefore he killed Carol Lockwood in a fit of rage. Enraged by this. Tyler swore vengeance against Klaus, and headed out to New Orleans, to avenge his mother and his fallen friends. After a hectic battle, Tyler was shown to be a worthy opponent despite being outmatched, and was eventually defeated by Klaus, who compelled Tyler to leave and know that he meant nothing to him. Tyler and Klaus were arch nemesis' and had the most intense rivalry on the show. The current state of their feud now is unknown, and possibly ended now that the two have gone down very different paths. Klaus being a father, and Tyler being a vampire hunter.

==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.
==Name==
*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. It is also a shortened name of Niklaus. In Ancient Norse: ᚾᛁᚲᛚᚨᚢᛋ ᛗᛁᚲᚨᛖᛚᛋᛟᚾ.
*Mikaelson is of of Scandinavian origin and means "Son of Mikael". 
==Tropes==
*Chronic Backstabbing Disorder - 'nuff said.
*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 .
*A Day in the Limelight - Has an episode named after him. Due to his nature at the time, it also classifies as a Villain Episode .
*Actually fits the Evil Brit accent trope - as the only character on the show with a British accent, this has not been averted nor inverted.
*Monster Sob Story - Due to an illegitimate birth, his step-father Mikael is unjustly more volatile towards him. See Abusive Parents . See also Cry for the Devil .
*Magnificent Bastard - Averted due to Villainous Breakdown
*And I Must Scream - Shared with family. However, instead of being daggered, Klaus must literally be chained and desiccated. When Alaric was turned into a vampire/vampire hunter, Klaus could do nothing to prevent Alaric from staking his desiccated body with the white oak stake .
* SelfMadeOrphan - Niklaus has killed his legal-father and mother.
* Papa Wolf Overprotective Dad- Klaus is very protective of his daughter and has no limits when it comes to Hope's safety and well being. He even killed his own father in order to protect his daughter after he found out about Hope still being alive. Klaus trusts nobody apart from himself when it comes to Hope and his love for her has no bounds.
