Esther Mikaelson ~ "Resolution through violence! You are nothing if not consistent. Go ahead. Strike me. I imagine you've been waiting a thousand years to do so".

Esther Mikaelson is the mother of the Originals and the witch who turned them into vampires. She was killed by Klaus, but when she is awakened by Bonnie and her mother, she comes up with a plan to kill her children. She is again killed by Alaric after turning him into a vampire to kill the Originals.

In the season 1 finale of The Originals, she gets back from the dead in the body of one of the harvest girls, Cassie. She brings back with her Kol and Finn. In season 2, she wants to purify her sons by offering them to switch bodies and become humans again. She starts to get the werewolves to her side by creating moon stone rings for them. She then reveals herself to Klaus and Elijah and jumps in the body of an other witch, Lenore. When Elijah and Oliver saves the werewolves from being enrolled in the wolves army, she comes with Finn at the end of the fight, takes Elijah hostage and puts a spell on Oliver which makes him die a few days later. She tries to convince Elijah to give up his vampire condition by making him relive his past in his dreams and see what horrible things he has done. In a flashback, we see that she had to give up her first child (a girl named Freya, Finn's twin sister) to her sister Dahlia because of a pact she made with her in order to have kids. Every fist born child of their bloodline must be given up or Dahlia will come back to kill them all. In Chasing The Devil's Tail, Esther asks Finn to bring her Cami and as he doesn't show up, she goes to Cami and puts a spell on her in order to welcome Rebekah in Cami's body. She reunites with Kol and Rebekah when he brings her the white oak stake and she comes to accept her offer for a new life. Just as she begins her spell, Rebekah finds out Esther hasn't been telling all the truth and has other plans for her children. She wants to put them in some human bodies and to destroy their vampires ones with the white oak stake. Kol and Rebekah who didn't know about that, tries to convince her to stop the spell, but it's already done. After a final confrontation with Klaus, she prepares to jump into another body but is stopped by Davina's spell and is killed by Klaus. Esther later wakes up and realizes she died with Rebekah's blood in her system, and as Klaus explains it to her she will no longer be a witch and have to choose between being a vampire and hating herself, or letting herself die. Klaus walks out as she starts crying.
