|“||You died with vampire blood in your system. It's a delicious irony, because, as you know, you cannot be both witch and vampire. So, now, you can either be the thing that you hate the most, or you can be dead. Your choice. Which is more than you ever gave us.||”|
Niklaus Mikaelson, often referred to as Klaus or Nik, is the main protagonist of The Originals. He is a former main character, antagonist and anti-hero of The Vampire Diaries. Klaus is an Original Vampire and a Werewolf, making him the Original Hybrid. He, alongside Mikael are possibly the strongest and most powerful supernatural characters in the entire series' universe.
Klaus is the son of Ansel and Esther Mikaelson and the step-son of Mikael. He is the maternal half-brother of Elijah Mikaelson, Rebekah Mikaelson, Kol Mikaelson and Finn Mikaelson, Henrik Mikaelson and Freya Mikaelson. Klaus is the father of Hope Mikaelson, the mother being Hayley Marshall. He is also the adopted father of Marcel Gerard. Due to his werewolf gene, Klaus is a distant relative to Cary.
Klaus was first mentioned in the second season of The Vampire Diaries 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 vampire-werewolf 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 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 Salvatore. 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, after a long time they are now friends. In New Orleans, he has 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 saves his daughter and now they work together to bring down their enemies. He also truly cares about the bartender Camille O'Connell, whom he has a close relationship with.
Klaus is also the first undead creature in the history of the series universe known to have impregnated a woman. He was under the curse of the Moonlight Ring's forged with his blood, meaning that every werewolf who draws on them to prevent their transformation on the full moon will be drawing energy from Klaus himself. The Moonlight Rings forged from Klaus' blood have been destroyed so he no longer is weak every full moon.
Klaus is a member of the Mikaelson Family, and a member of an unknown Family of Werewolves. He is connected to the Labonair Family, a royal werewolf family via his daughter, and a member of the North East Atlantic Pack.
Mystic Falls, The Middle Ages, 10th Century
Niklaus was born to Esther and Ansel 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 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 he is scared off by Mikael who stated 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 realized 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.
Esther found little Klaus in that woods once when he was hiding before Mikael. He was afraid so she gave him a necklace which should protect him and remind him that Esther will be always with him. Few years later Mikael hurt Klaus in the woods during a fight. Esther helped Klaus to heal. Klaus told her about the fight and that Mikael wanted to take him the necklace. In episode Every Mother's Son Klaus found out that the necklace made him weak because of Esther's spell - she didn't want him to be strong, kill somebody and became trigger the werewolf gene.
Both Niklaus and Elijah were in love with Tatia, even though she had a child with her husband who died in battle.They both vied for her attention and even had arguments and blows over her, she eventually chose to be with Elijah. Unknown to Niklaus. Elijah killed Tatia by draining her of her blood. 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.
Cadiz, Spain, 1702
In 1702, Kol's violence in Spain drew too much attention and brought Mikael, straight to the family, burning the country in his wake. While the flames drew closer and Mikael beheaded Klaus' horse,Theo. Elijah and Klaus searched for Kol while Rebekah brought the daggered Finn onboard a ship to flee from Europe. 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,18th Century to 20th Century
Having fled the Old World, escaping Mikael , Klaus, along with Rebekah, Elijah, and their daggered brothers 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 wouldn't be a wise 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.
He later meets the Governor to ask for Marcellus' freedom and chokes the Governor's neck until he grants the freedom. Niklaus asks Marcel about his father and quotes that family can be more than just those with whom they share blood and that they can choose. Marcel looked touched by his words.
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.
Klaus grew jealous as Marcellus grew closer to Elijah rather than him. Feeling lonely, he undaggered his younger brother, Kol, so he'd have someone to have fun with. The two began happily causing chaos across New Orleans, even slaughtering an entire tenement building for fun. When Klaus revealed that he'd choose Marcellus over Kol, though, Kol grew angry and threatened to turn Marcellus into a vampire. Klaus, realizing his brother was too wild to control, daggered Kol yet again.
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 the same year, Marcel gets shot by the the Governor while trying to free some slaves. A dying Marcel forces Klaus to turn him into a vampire or let him die as a human. Niklaus against his wishes, gives in and fulfills Marcel's desire to become a vampire.
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.
1919In 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 1920's, 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.

- "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 shown to have developed strong paternal instincts since the birth of Hope. One such case is his belief a parent who trades their child for anything deserves a punishment worse than death. Klaus has also mellowed great deal a since season 1, so much so he, in an ironic twist of fate, restrained Elijah when he lost his temper when Finn threatened Rebekah (and unknowningly Hope) unlike before where he would just let the blood flow.
Klaus has also developed strong friendship instincts. One example was when he gave up an opportunity to kill Mikael when he threw Tunde's Blade at Cami and chose to sage guard her life over killing Mikael.
- Main article: Niklaus Mikaelson/Appearance
Klaus is an attractive man. His height is 5'11. Klaus possesses curled dirty-blond 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 necklaces as seen in some scenes at the beginning of Season 3.
Powers and Abilities
As an Original Vampire, and later the Original Hybrid, this makes Klaus possibly the strongest of the Original Vampires, however with Mikael now resurrected, he may be weaker, equal, or superior to him. His Werewolf side has given him additional powers and abilities the others do not possess, making him among the most powerful supernatural beings in the world. though his maternal half-siblings and his step-father have been able to fight him on almost even terms, and he feared Mikael; while he had the White Oak Stake. His powers and abilities improve with the consumption of human or vampire blood, assuming his werewolf form or utilizing his lycanthropic enhancements and the full moon. In Live and Let Die, it is shown that Mikael is slightly stronger than Klaus, although it should be noted that he was still effected with werewolf venom and Klaus was not using his full powers and abilities.
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. In Every Mother's Son, it has been hinted that Klaus' swordsman skills are superior to Mikael's.
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. In that single fight, he killed roughly twenty four non-original vampires single-handedly, showing his skills as a combatant even further. Klaus is far less calm, composed, and strategic in battle than Elijah. Due to his long existence, Klaus has seen countless battles and is very experienced in battle.

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.
