Niklaus Mikaelson

Niklaus Mikaelson is the (former) primary antagonist of the Vampire Diaries and the (current) main protagonist of its spin-off tv show, the Originals.

Klaus is known to be a malevolent, cruel, sadistic, brutal, ruthless, manipulative, impulsive and narcissistic character, who has a tendency of daggering his family (due to them betraying him as Rebekah left him and Elijah tried to kill him) and is a feared Vampire-Werewolf Hybrid who has made lots of enemies.

However, behind all that, Klaus is a troubled and complex character with lots of inner demons to fight as this was caused through his brutal step-father, Mikael, who tortured him and made his life hell before he was turned into a vampire.

Klaus is actually the child of another werewolf named Ansel, whom Esther committed infidelity with and this made Klaus kill his mother.

As a result, Klaus is evil and power-hungry because that is a facade of him being lonely.

His anti-heroic and anti-villainous side is widely shown in the Originals as he received a tip that the witches were plotting against him and the werewolf Hayley, is pregnant with his child, which is the secondary central plot of the show as Klaus, Rebekah, Elijah and Hayley worked to protect the child as the witches were plotting to kill her.

The child brought out the humanity out of Klaus and he wasn't too keen on protecting the child at first but later on he decided to keep his daughter because he doesn't want to end up like Mikael.

Therefore, this doesn't make Klaus irredeemably evil, it just makes him a tragic protagonist villain. So for Heroes Wiki, here are the heroic moments of the Original Hybrid as well as his anti-heroic moments....
