The Vampire Diaries: 10 Unanswered Questions We Still Have About Klaus

Klaus Mikaelson started out as the main antagonist in the successful vampire TV show The Vampire Diaries. Klaus first appeared in the second season and he planned to perform a magic ritual that would unlock the part of him that was a werewolf and would change him into a werewolf-vampire hybrid.

To do that, Klaus tried to kill the main heroine of the show, Elena Gilbert, but things didn't exactly work out the way he planned. Klaus later moved to his own show The Originals but even though his story is now over, there are still a few unanswered questions the fans might have.
