Buffy the Vampire Slayer
Spike, or William the Bloody, (played by James Marsters) was an English vampire. He was born in London around 1853. He was turned into a vampire in 1880 by Drusilla, a pretty vampire created by Angelus. He spent the next 20 years with Angelus, Drusilla and Darla as they killed throughout Europe and Asia. After Angelus got his soul back and left, Spike and Drusilla continued for 100 years before going to Sunnydale to try and find him. Later, Spike fell in love with Buffy. He fought a demon (initially to get his chip removed) and got his soul back and helped save the world in the last episode ("Chosen"). He was sent, by the amulet he wore, to Angel. (Stars in the final season of Angel).
