The Immortal

""We're immortal." "Not like him. I mean, he's not some common vampire. He's... I don't know what he is. A giant. A titan straddling good and evil, serving no master but his own considerable desires.""

- Spike and Darla on The Immortal.

The Immortal is the only known name for a seemingly highly charismatic villain in the Buffy the Vampire Slayer spin-off TV series, Angel.

History
The Immortal was an old rival of both Angel and Spike; an extremely respected and admired being serving no side but his own desires. He had accomplished numerous incredible feats and managed to seduce many women, including Darla, Drusilla and, supposedly, Buffy Summers, though this was merely a decoy. Quite little is truly known about the Immortal, although according to Darla, he wasn't "some common vampire". It is also known that he didn't use magic, considering it "dirty", and according to Angel, was centuries old, had a dark past, and he "may or may not [have been] evil".
