Claire Holt as Rebekah Mikaelson

Rebekah Mikaelson is a free-spirited Original Vampire. Rebekah was the lover of Stefan Salvatore back in the 1920's, daughter of Mikael and Esther, and also the only sister of Elijah, Finn, Kol, and Henrik, and the only half-sister of Niklaus. After the death of Henrik, she became the youngest in the family. Rebekah has the most impeccable instincts and can tell when people are lying to her or others. This is something Klaus calls "borderline supernatural."

Rebekah is a member of the Mikaelson Family.

Rebekah is the only daughter of Mikael and Esther, who were wealthy land owners from Eastern Europe in the 10th century. She is the sixth of seven siblings, which includes Elijah, Finn, Niklaus, Kol, and Henrik and a unknown older brother who is presumed dead. Not much is known about Rebekah's early life, other than that she was born in the New World, where they lived in peace among the Werewolves for twenty years. However, during a full moon, when the wolves were transforming, Klaus and Henrik snuck out to watch the villagers transform from men to beast. As the sun began to rise, Rebekah saw Klaus carrying Henrik's lifeless body back into the village. He stated that one of the wolves had mauled Henrik to death.

Not wanting to lose another child, their mother Esther cast a spell (Vampiric Transformation Ritual), calling upon the Sun for life and the White Oak Tree for immortality. However, the spell lead to some untimely acts. Unbeknownst to Rebekah and her siblings, they drank wine laced with the blood of Tatia for dinner, and afterwards, Mikael drove his sword through their hearts. After their awakening, Mikael forced his children to feed on a local villager therefore completing their transition into vampires.

"Together as one, always and forever" Later, they began to realize their new gift had its weaknesses. The flowers that grew at the base of the White Oak Tree, vervain, burned them and prevented compulsion. The sun burned their skin, making it impossible to walk in the day light for them. They were unable to enter the homes of their neighbors without an invitation. Also their thirst was insatiable. Realizing that a wood carved from the White Oak Tree would be fatal to them, they burned the tree to the ground. After their mother's death, Rebekah, Klaus and Elijah swore to each other that they would never turn on each other and stick together as one, always and forever.
