You are a Mikaelson. You're my blood. And I need you. I need you by my side.

This is the relationship between half-brothers the Original Hybrid, Niklaus Mikaelson and Original Vampire, Kol Mikaelson. They are two half-brothers of the family, The Original Vampires. Kol and Klaus both have a short temper. It is known that Klaus has daggered Kol on numerous occasions over the centuries. However, despite this, Kol has forgiven Klaus for daggering him and his siblings and they now share a close relationship. Their current bond is unlike any close bond they ever or possibly might have shared throughout the centuries.


They were both born and grew up in a village now known as Mystic Falls where they were turned into vampires.

1002, Southern France


Klaus and Kol in their early days as vampires

While on the run from their father, Kol seemed to be an instigator in getting his brother to embrace his newfound bloodlust; wanting him to enjoy his killings and feedings as if they were real meals. When they came across Lucien, a servant in a nearby castle, Kol voted to kill him since he saw him as nothing more than dessert. When the votes were tied between the siblings, it was up to Niklaus to be the tie-breaker and despite Kol's hunger, Klaus voted to let Lucien live. Klaus and Kol, along with their siblings, were aided by Lucien in blending in at his castle and presented as nobles.

1114, Italy

Throughout this time, Kol was in eastern Europe, presumably making the Originals famous with his actions; killing and turning people indiscriminately. Klaus, Elijah and Rebekah had heard stories of his actions from their own travels, as mentioned by Elijah. Kol and Klaus crossed paths again when they went to a party held at a vampire hunter named Alexander's home. They were later daggered in a surprise attack but Klaus was able to revive Kol, along with the rest of their siblings, as he was unaffected by the daggers.

1702, Spain


Klaus and Elijah daggering Kol

Kol's antics in Spain contributed to Mikael being able to track down the Original siblings. As Elijah, Klaus and Rebekah were planning to flee Europe, Elijah and Klaus found Kol in a tavern and made to convince him to join them. Kol decided that he preferred the idea of staying in Spain, suggesting that Mikael would ignore him in favor of chasing Klaus as their father had always hated him more. Klaus told him that he didn't have a choice, and Elijah and Klaus daggered him to get him on their ship.

1821, New Orleans

Kol remained daggered when they fled Europe and arrived in New Orleans. He remained like this for over a century until Klaus decided to undagger him. Klaus removed the dagger while he was drunk, craving fun that he believed Elijah had stolen from him with his doting on Marcel. Klaus appeared amused when Kol devoured his gift for him and both ignored Elijah's concern. Kol and Klaus began causing trouble together, killing what was reported to be forty-six people in a building but Kol corrected that it was probably at least sixty, saying that the reports had probably forgotten the victims in the attic. When Klaus revealed that he'd rather put Kol back in a box than send Marcellus away, Kol grew upset, angry that Klaus would choose Marcellus over his own brother.

Klaus prepares to dagger Kol

Later, Kol showed Marcellus the theater by compelling a large number of people to perform Hamlet but to have all of the murders in the play to actually be enacted and be real deaths. He forced Marcellus to watch it until Elijah showed up to stop him. Kol revealed that he was just training Marcellus how to be a vampire since he knew that Klaus eventually wanted him to be one. He had even fed him blood already and told Elijah all he had to do was kill him. Elijah grabbed Kol, furious and condemning him for his vile and sadistic imagination. Klaus intervened, telling him to let Kol go. When Kol thanked Klaus, his half-brother daggered him yet again, seeing him as being too wild and a threat to Marcellus.

1900's, New Orleans

Kol is caught by Klaus

Kol was eventually undaggered (presumably by Klaus) again and lived in New Orleans with his siblings in the 20th century. Kol plotted with some of the witches in New Orleans against Klaus, wanting them to alter one of the daggers so it would be able to work on Klaus. To channel enough power to create the dagger, his witches needed a large paragon diamond. When Kol managed to steal one, he was found out immediately after by Klaus and Marcel who confronted him. Kol was forced to hand over the diamond and Klaus had his own witch trap Kol's witches inside the house they stole the diamond from.

Klaus daggers Kol for his scheming

Kol, furious by the loss, searched for the paragon diamond in Klaus' belongings, carelessly tossing them aside in a mad scramble and was found by his sister, Rebekah. To stop her from telling Klaus that he had been going through his things, Kol he told about his plan to dagger Klaus, hoping that she'd join him since Klaus treated her even worse. Rebekah, however, ratted Kol and his plan out to Klaus. Klaus, in a speech to his party-goers, revealed that he knew of Kol's plan. Kol tried to flee but was caught, daggered by Klaus and kept neutralized for the next one hundred years.

The Originals


  • The two share a reckless and impulsive nature, having been responsible for the Original Vampires' growing infamy in the early 1100s.
  • Despite bickering frequently, their relationship is far less hostile than Elijah and Klaus'. As they have been shown to be on good terms with each other, going out for drinks together and Kol doing Klaus a favor by keeping an eye on Jeremy in Denver.
  • Kol seems to view Klaus as a monster, often comparing Rebekah's hostile actions to Klaus', such as when she took a group of Mystic Falls vampires hostage at the school and especially when she was prepared to dagger him like Klaus had, scolding her by telling her she's "no better than Niklaus". This seems to stem from what his family has been through and knowing Klaus caused a lot of it. He even described Klaus' actions in the past as "horrors" to Elena.
  • They both threatened their younger sister Rebekah with the white oak stake to scare her.
  • Like Rebekah, Kol generally refers to Klaus as "Nik".
  • Almost every time they are talking, they get into an argument; however, it is not to the point of being physically violent to one another, as their relationship is far less intense then Elijah and Klaus', as they are on good terms with each other.
  • Still, they do love each other and are protective of each other.
  • Kol is closer to Klaus than he is to his other brothers.
  • Their relationship is quite a bit different than Elijah and Klaus as Elijah thinks he can save Klaus from complete self-destruction where Kol accepts the person Klaus is as they both are unpredictable, menacing, a tad sadistic, dangerous with an amazing amount of temper and unreasonable.
  • Klaus is the only one who calls Kol "Little brother".
  • They also both keep their word to the fullest extent but always look for loopholes.
  • Kol by means of Davina cast a spell to rescue Klaus from death.
  • Klaus finally lets Kol back into the "always and forever" pact that was made when they were kids, then again with only himself, Elijah and Rebekah. He only did this after explaining to Kol that he really had mourned his death.
  • Kol found out that Hope was alive, finally being involved in the secret that his family was so adamant in keeping, and he gained Klaus' trust after Kol helped save his daughter from Finn.
  • Klaus possessed the ashes of Kol's true body; this reveals just how much he cares about and loves his half-brother.
  • They along with Finn are the only remaining originals without a sireline, Kol's sireline died along with him in A View to a Kill, and Klaus's sireline was unlinked by Davina Claire on A Streetcar Named Desire.
  • Ironically having a sireline was a protection for Klaus, when it was the reason Kol died (first death).
  • Klaus, along with Rebekah, are the only living siblings that Kol isn't angry with. He is angry with Elijah and Freya because they let Davina die.
