Klaus has been undead since at least 1491, when he met Katherine at his family’s estate in England. He tried to use the Petrova girl to break the curse that made him vulnerable to daylight and unable to harness his werewolf power, but was unsuccessful. Although she managed to escape Klaus’ clutches, Katherine had to turn vamp to do so.
It took hundreds of years for Katherine’s doppelganger to come into existence, but it finally happened in the form of Elena Gilbert. The necessary ingredient to his curse-breaking spell was enough to lure Klaus to Mystic Falls, and he’s clearly not through with E and her crew yet.
Fast facts:
- 1. Klaus’ exact origins are still unknown, but he comes from a family full of bloodsuckers, including his older brother Elijah.
- 2. After (sort of) killing Elena and murdering Aunt Jenna, a witch, and a werewolf, Klaus garnered full use of both his vampire and werewolf sides when he broke the Sun and Moon Curse.
- 3. Because he’s an Original and a hybrid, it’s damn near impossible to kill Klaus.
