Angel

A tall, dark, Irish gentleman born in early 1700's, Angel was a young man who liked beer as much as he liked women. During a drunken binge he was sired by the vampire Darla and becomes Angelus, the one with the Angelic face, the scourge of Europe. He leaves his home in Galway and travels the world.

In 1860 he ends up in England where he kills a young woman's entire family driving her insane before making her a vampire (Drusilla). His taste for the dark side ends in 1868 when Angelus feeds off a young Gypsy girl in Romania, causing her tribes elders to curse him with a conscience and the return of his soul.

Despondent and horrified by his past evil deeds, Angel wanders aimlessly feeding off vermin instead of humans. He ends up homeless in New York in 1996, where Whistler, a demon whos duty is to maintain the balance of good and evil, rescues Angel by convincing him to make something of himself.

Constantly atoning for his many transgressions, Angel as the quintessential tortured guy, falls in love with Buffy and make it his mission to help out the Slayer by homing her attention into razor sharp clarity and even battling come fellow vampires.
