Now before anyone starts yelling at me because I didn't include any of the vampires from Twilight, The Vampire Diaries, or True Blood; I will say calm down and take a deep breath. I didn't include them because I can't stand Twilight, The Vampire Diaries boys are too new on the scene, and I haven't watched even one episode of True Blood. Now I will admit that these characters will probably be on the lists of everyone else so I don't feel too bad by not including them on mine.
So I will separate my list between the men and women, 5 of each. With no further ado, here is my list (In no particular order).
Michael, as played by Jason Patric in "The Lost Boys". Michael never fully makes the change but he is well on is way before he is saved by his younger brother.
Julian Luna, as played by Mark Frankel in "Kindred: The Embraced". Julian is the Ventrue Prince of San Francisco in the TV show based of the RPG Vampire: The Masquerade.
Henry Fitzroy, as played by Kyle Schmid in "Blood Ties". "Blood Ties" was a TV show based off of a series of books by Tanya Huff.
Deacon Frost, as played by Stephen Dorff in "Blade". "Blade" was based off a Marvel comic book series where the character of Deacon Frost was much older.
Angel, as played by David Boreanz in "Buffy: The Vampire Slayer" and "Angel". Angel was not supposed to be a regular character but he proved so popular with fans he was added to the cast and eventually given his own show.
Selene, as played by Kate Beckinsale in "Underworld" and "Underworld: Evolution". Selene was a Death Dealer, a warrior fighting the Lycans.
Lilith, as played by Angie Everhart in "Bordello of Blood". Lilith is the owner of a whorehouse ran by vampires.
