10. 'True Blood': Russell Edgington Stakes Roman Zimojic (Season Five, Episode Six)
Deaths on True Blood are so commonplace, the only way to shock the fans at this point is to kill off a major character as soon as he or she is introduced. That's exactly what happened to megalomaniac vampire Roman Zimojic, whose storyline came to a screeching halt after just five episodes at the hands of the diabolical Russell Edgington – proving once again that no character, however powerful, is safe on this show. This rule of thumb re-emerged at the season's end, when we bade a blood-teared adieu to Russell himself (staked by Eric Northman, settling a 1,000-year grudge), and when, after downing a vial of vampire goddess Lilith's blood, Bill Compton was reborn an indeterminate hybrid the interwebs have unofficially dubbed "Billith."
