James Marsters plays Spike. A mean vampire who already has the deaths of two slayers on his credit. Once known as William, the Bloody, Spike was named for his vicious tactics of killing with railroad spikes. Throughout the second season, we have seen him go through many struggles, especially with his love, Drusilla.

When Spike and Drusilla first entered the Buffy scene, Drusilla was weak after an attack by an angry mob. Spike's purpose for moving to Sunnydale was to make her strong. While trying to restore her strength and kill her sire, Angel, Buffy came in to ruin the fun. Drusilla however, was restored to full power, but Spike was crushed under a large organ.

The organ accident left Spike in a wheelchair with a scared face. Drusilla, now strong has the intentions to take over the world. When Angel reverted back to the evil Angelus, he slowly took Drusilla away from a defenseless Spike. In Becoming (the season finale two-parter) Spike joined forces with Buffy to keep Angel from sucking the world into Hell. He revealed to Dru and Angel that he could walk by beating Angel with a crowbar. While Buffy and Angel fought, Spike took off with Drusilla and drove away from Sunnydale.

Spike returned in the third season in the episode "Lover's Walk" in search of revenge and a way to fix his relationship with Drusilla, who had left him. He returned later in the fourth season, bringing along his new girlfriend, Harmony. Spike was searching for a ring called the "Gem of Amarra" and when he found it things got intersted. He did however loose the ring and was forced to return to Sunnydale seeking revenge yet again. Instead, he was caught by commandos from the underground opperation called The Initiative.

He escaped, but an implant in his head now prevents him from hurting humans. Promising information on the Initiative to the Slayer, Spike was given blood and a place to stay that was safe from the sun. In the episode, "Doomed," Spike discovered that while he can't hurt humans, he can hurt demons.
