Angel, "Angel"
The show: Set in Los Angeles, this "Buffy" spin-off features Angel as he becomes a private detective. Using an array of supernatural powers, he helps the lost souls of the world find their rightful place again.
The vampire: Angel is an ever-changing vampire soul. He's good, he's bad, he's good again. By the time Angel gets to his spin-off, he seems to be on a permanent "good" kick, but ladies be warned: This one will change, but he might not change the way you want him to.
