— Brothers Mikaelson.

Niklaus is an unpredictable person, as every member of his family, living or dead, has said. He is a very temperamental person, since you can become his most valuable ally, as well as his next prey. His way of thinking is very complicated, he believes in himself, he is arrogant, very ambitious and often conceited. On the other hand, Klaus is a very persistent person, he fights for what he wants, he protects those he loves. Kol is menacing, unstable, and somewhat unreasonable. He can quickly go from being a respectful gentleman to bossy and aggressive. When Kol is introduced to Carol Lockwood, he greets her with dignity and respect, but when Damon Salvatore is introduced to Kol, he speaks to her very condescendingly. Kol patronizes his siblings often, challenging them with snark and contempt, especially Rebekah and Niklaus. He likes to break the rules. He is described by Julie Plec as "brash". However, despite his flaws he is shown to truly care for his family as seen when he attacked Damon for Finn's death despite Finn trying to kill him and his other siblings and when he helped his sister after she had been undaggered. When threatened by Rebekah's dagger, he is even shown to be ashamed of what his family has become. Elijah is a diplomatic, elegant and bold person. He is extremely intelligent, and unlike his brothers, he prefers to speak first before attacking. Although he has also shown to be fierce and overprotective of those he loves.
