'The Vampire Diaries' Season 4 introduces new hybrids: Blake Hood and Alyssa Diaz cast

Klaus' clan of hybrid werewolf-vampires is growing, "Vampire Diaries" fans! At the end of last season, he nearly drained Elena of all of her doppelganger blood -- and now he's putting that blood to good use as he creates some new hybrid monsters to support him in the new season.

"The Young and the Restless" star Blake Hood and Alyssa Diaz of "Nine Lives of Chloe King" fame have been tapped to star as Klaus's newest minions, appearing in Episode 5 and Episode 6 respectively. Dean and Kimberly are under Klaus's control due to their sire bond with him, so there's no telling the damage they'll cause. The casting was first reported by TVGuide.

Now that Elena has turned into a vampire, Klaus' motives this season are still a little unclear. We know he's not going to be pleased with his sister Rebekah for "killing" his only doppelganger blood source, and we know he's got designs on whisking Caroline into a more glamorous life. Aside from that, though, we have yet to learn what will keep Klaus in Mystic Falls after he gets his own body back at the end of the first episode.
