Katherine Pierce is a 540 ano old vampire.

klausyxcarebear The chance to save humanity and the world is here… The most miserable time of her 500 years of existence was the moment that Katherine became human again. She had to learn the meaning of pain, patience, manners and working for something instead of using compulsion. And it was laughable to watch her try. That was all until the Greater Power contacted her with an offer she simply couldn’t refuse; her immortality back in exchange for utilising her conniving and manipulative ways to help end the world. Of course, she had agreed. But then, Katherine always was known for her double standards. She hadn’t exactly expected to wake up in London, her thirst for blood renewed and overpowering. She thought she was dreaming which wouldn’t have been anything new. But then she had her first taste of blood in about a year and her whole body felt alive. It was the most perfect thing she had ever tasted. She was in a new city, London during the apocalypse to be exact, with fresh meat and she couldn’t help but take the chance to have a little fun. And the first person on her list? Hello Elena. Katherine Pierce is portrayed by Nina Dobrev from The Vampire Diaries. She is ready to join the fight.
