“ Your trap failed Mother. I still live and I will go on living and should your beloved spirits try to preserve you again I dare you to come after me. I will build an army so big no one will ever touch me. My survival will haunt you for eternity. You will never destroy me! ” — Klaus to Esther in Do Not Go Gentle Niklaus Mikaelson (a.k.a. Nik or Klaus) is an Original/Hybrid, and the son of an unnamed werewolf and Esther. He has six siblings that consists of five half-brothers and one half-sister. A deceased unnamed older brother, four other half-brothers named Elijah, Finn, Kol, and Henrik. And a younger half-sister named Rebekah. Klaus is also the step-son of Mikael, with whom he had a strained relationship with. He is first mentioned in an conversation between Rose and Stefan warning him about the Originals. 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 members of his inner circle. For over a thousand years Klaus has been trying to a break a curse that bound him to a moonstone. He created the myth of the sun and moon curse in order to help find the moonstone and the Petrova Doppelgänger that was needed to break the actual curse. His goal was to bring out his werewolf side so he could sire his own super race. In 1492, he finally got his chance to break his curse when he met Katerina Petrova, the final piece for the ritual. He kept her entertained until the full moon, but was unaware that she found out what he was and what he wanted from her, causing Katherine to escape from him. After Katerina turned into a vampire he assumed that her family line ended with her and that his chance to break his curse was forever gone, Klaus traveled to Bulgaria and slaughtered her entire family in revenge. For the next 500 years, Klaus was searching for a way to break the curse without the doppelgänger and had forced generations of witches and warlocks to help him for centuries. Along his search for a way to break his curse, Klaus hunted down his family and neutralized them. Also he was searching for Katerina Petrova, who escaped him and stole his moonstone.

Klaus has six half-siblings and a step-father named Mikael, who was a wealthy landowner who moved with Esther to the New World when their home village was devastated by a plague. Klaus was close to his family with the exception of Mikael, this was because Klaus was not his son and from a different bloodline. Many years before his mother had an affair with a man from a different species. When his brother Henrik was killed by a werewolf, Esther performed a ritual which transformed Klaus, his siblings and his step father into <img src="http://images2.wikia.nocookie.net/__cb20111105193137/vampirediaries/images/thumb/ 7/7b/Henrick_died.jpg/180px-Henrick_died.jpg" width="180" height="125" class="thumbimage" />Esther and Niklaus looks at Henrik's body vampires. When he made his first human kill, his werewolf gene was activated, thus informing Mikael of Esther's unfaithfulness. Mikael then hunted down and killed Klaus' father and his entire family, not realizing that he was igniting a war between vampires and werewolves that has been perpetuated across the ages. Soon after becoming a vampire and discovering his werewolf bloodline, a curse was placed on Klaus by Esther, forcing his werewolf side to lie dormant and then abandoned him. In retaliation, Klaus murdered his mother, and framed Mikael for the act. 1114 <img src="http://images1.wikia.nocookie.net/__cb20121102054104/vampirediaries/images/thumb/ a/a7/Hgfd.jpg/150px-Hgfd.jpg" width="150" height="100" class="thumbimage" />Klaus and Elijah in Italy.

Surprised to hear of his father's death, Elijah asks why their family remains in the coffins. Klaus asks Elijah to help him to get the fourth coffin back from Stefan by reminding him of the oath that they had sworn to one another: 'always and forever'. Elijah then organizes a dinner between Klaus and Stefan with Damon present. The deal offered by the brothers is that, in exchange for the coffin, Klaus will leave Mystic Falls forever, a deal that Elijah deems to be fair. Klaus later counters with his own offer: Elena's future happiness with a human husband (Matt Donovan) in exchange for the coffin; this would keep her safe from what he deemed to be feuding between the Salvatore brothers and would ensure the continuity of the Petrova bloodline so that he could keep creating hybrids. Stefan refuses the deal. Klaus then grabs him and burns his hand in the flames while Elijah prevents Damon from intervening. Klaus tells Damon to bring him the coffin or he will kill Stefan. Damon complies and Klaus sends Elijah with him. However, Elijah and Damon returns after wards not with the coffin but with the daggers that Elijah had removed from their siblings.

Rebekah wishes to leave, but Klaus states that he will not leave without Elena, causing Rebekah to get angry and state that she won't care even if he does die, before leaving. Klaus then goes to Elena's house to collect her, however Stefan and Damon bar his way. He begins attacking the house from the outside, trying to force them to invite him in, but the manage to repel him. Just as he is about to cause the place to explode, Stefan comes out and says that Alaric has captured both Elena and Caroline and will only give them up if Klaus hands himself over. Klaus initially refuse, but Bonnie comes up with a plan that will allow them to actually succeed. He then agrees, but makes it clear that after this he is taking Elena and leaving. He waits in front of the school-where Alaric has Caroline and Elena-with Stefan and the two talk, Klaus trying to drive a wedge between the brothers again. When Stefan states that all of Klaus' attempts to break the Salvatore brothers apart has only made their bond stronger, Klaus counters by asking what will happen when Elena finally chooses between them. Then, Bonnie, Damon and Jeremy show up. Bonnie gives the vampires a vile of her blood, saying that once they drink it, all they have to do is make a connection with Alaric's heart, and she will use her magic to stop it, effectively neutralized him. After drinking the blood, Klaus enters the school with the Salvatores.

As she prepared to follow through with her threat Alaric went to stop her, freeing Klaus, who then ran off with her. He then began draining Elena of all her blood, that way gaining enough blood to at least have some hybrids, while also killing off the greatest threat to him. When Elena asks why he is killing her, as he won't have an unlimited army anymore, he states that he doesn't need one as he has his family back. Elena counters saying that they will never truly trust him again, and that he is wants a back up family, which is why he is draining her blood instead of simply snapping her neck. Later, Tyler shows up and tries to free her, but Klaus finds him before he can get Elena out of the house. <img src="http://images3.wikia.nocookie.net/__cb20120504105908/vampirediaries/images/thumb/ 8/85/Klaustruepersonality.jpg/180px-Klaustruepersonality.jpg" width="180" height="101" class="thumbimage" />Klaus expresses his softer emotions before dessicated He asks how Tyler broke the sire bond, and Klaus states that that is impossible, Tyler countering by saying that true love is more important than sire bond induced loyalty.

Klaus then prepares to kill him, but Stefan and Damon arrive. Tyler and Damon restrain Klaus, while Stefan plunges his hand into Klaus' chest, and Bonnie begins her spell again. Klaus looks at Stefan with a mixture of sadness and shock as his life fades away. He is then completely desiccated , and his dead body falls to the floor.

In The Departed, Damon stores Klaus's coffin in a warehouse outside of Mystic Falls. Bonnie arrives at the warehouse, and Damon tells her that he hid Klaus's coffin in compartment 1020, saying that compartment 666 would be too obvious (666 is the Devil's number, with Damon indicating that Klaus is the Devil).

However, he had a strained relationship with his father, Mikael, who was harder on him than on any of his siblings. Klaus even admitted to Rebekah that Mikael frightened him which made him constantly seek his approval without ever finding it. His mother, Esther, often tried to calm Mikael when he became angry with Klaus but she never tried to stop him from humiliating her son. This led him to resent both his parents and possibly to be jealous of his siblings for having their approval. Original/Hybrid Personality wise, Klaus is described as sadistic, careless, paranoid, impulsive, emotional, quick-tempered, volatile, manipulative, jealous, obsessive and competitive. Klaus has little to no regard for human life in general, the polar 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, he has shown to be very protective of his half sister, Rebekah, who stayed by his side for centuries. Unbeknownst to any, Klaus was not the son of Mikael, but of a werewolf in another village which made Klaus both aggressive and angry. When they became vampires, all these emotions were heightened and Klaus's temper became worse than ever. Years of humiliation at Mikael's hands and Esther's supposed indifference, coupled with her rejection of him as her son, led Klaus to kill his own mother in revenge. 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 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. However, Klaus's hunger for power actually hides a deep fear of being alone which must stem from his 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. Caroline brings out Klaus humanity.

Uninvited Invitation - In order to enter any house owned by humans, they had to be invited by that person. Once invited the vampire cannot be uninvited. If a vampire lives in a house, other vampires can enter freely and if vampire is in the house without being invited in it will become disoriented and will begin to suffocate. Esther - Klaus mentions in Bringing Out The Dead that Esther can kill him. Her knowledge of the spell that created vampires and thus ability to reverse it could be the deciding factor in this. Magic - As a supernatural entity Klaus can be harmed or killed by a witch/warlock that can channel enough power. Considering his level of power however this would likely be very difficult to achieve. Dessication - Like any vampire lack of blood will immobilize Klaus.
