Devilish  Klaus Mikaelson
"My brother may be the devil, but he is nothing compared to the hell that Emma will raise. She makes Klaus look like an angel."
If you made the assumption that everyone has heard of the five Original Vampires- Klaus, the Orignal Hybrid, Rebekah, the sister who falls in love all too easily, Elijah, the noble, Kol, the vain, and Finn, the selfless martyr- you would not be far off. The Originals are infamous and highly respected in the metaphysical society- practically being vampire royalty- and it is very seldom that you find a supernatural being who has not at least heard rumors of the first vampires. But what about the sixth original, Emmaline Petrova, the Queen.
Emma has been best friends with Kol and Rebekah Mikaelson for more than a thousand years, but has always been close with the other children of the Mikaelson bloodline, more noticeably Klaus. In short, the ruthless hybrid has a bit of a soft spot for the eldest Petrova daughter, proven by the fact that he has only ever daggered her one time.
Emma has never been an ordinary girl, even in her human years. She had a few secrets, one of them being that she has a gift that she inherited from her grandmother that was not passed onto her mother nor her sisters. A gift that, for centuries, she assumed she had lost.
Emma was once a sweet girl full of compassion but after more than a thousand years of roaming the earth, she has changed. She is loyal, noble, protective, has a temper unmatched by any and is more ruthless than Klaus could ever be. But more importantly, she is a powerful hybrid; half-witch and half-vampire, a heretic. But this is a secret only known by herself and Klaus, bringing the two souls closer than ever.
What will happen when Emma returns to the place of her birth to protect her very great niece, Elena Gilbert? Only time will tell, but one thing is for sure, you don't want to end up on her bad side.
