Buffybot

The "Buffybot" was a robot replica of the real Buffy Summers created by Warren Mears at the behest of Spike. Though it was a perfect physical duplicate of Buffy, and possessed detailed knowledge of Buffy's life, friends, and family, the Buffybot's mannerisms and speech patterns were stilted and imperfect by human standards. It also lacked nuance and tact, and could be disturbingly blunt in conversation.

Biography
The Buffybot was built by Warren Mears as a sex toy for the vampire Spike, who at the time had developed an obsessive attraction for Buffy. Therefore, the Buffybot was initially programmed to be in love with Spike and do anything to please him. Buffy's friends mistake the robot for her, and Buffy later poses as the Buffybot to find out whether Spike betrayed her and Dawn to the hellgod Glory, presenting him with a kiss when she discovers the lengths he went to protect them. In the Season Five finale, "The Gift", Xander and Anya find the deactivated Buffybot in the basement of The Magic Box. The group decides to use it to make the first strike and distract Glory from the real Buffy. After a few minutes of battle, the Bot is decapitated by Glory and the real Buffy then reveals herself.

In the first two episodes of Season Six, following Buffy's death, the Buffybot is used for patrolling to ensure the underworld does not discover the Slayer's death; if demons think Buffy is alive, they are less likely to strike, out of fear. Willow also reprograms it for Slayer duties, but its original programming occasionally resurfaces, which both pains and irritates Spike. Its impersonation also ensures that Dawn, lacking a legal guardian in Sunnydale with both Buffy and their mother dead, can stay in town with the Scooby Gang and allows the group to live and operate out of the Summers home. Unfortunately, one vampire discovers the secret when fighting with it and brings a demon biker gang to Sunnydale to tear the place apart. The demons destroy the Buffybot by tearing it limb from limb, pulling it apart with motorcycles. Before "dying", the Buffybot reveals to Dawn that the real Buffy has returned from the dead. Buffybot has not since been repaired.



Trivia

 * She pronounced Giles' name "Guy-els"
 * She was originally programmed by Spike to dislike Angel. Her programming referred to him as "lame. His hair goes straight up and he's bloody stupid."
 * A slice of her faux skin around her torso peels back to reveal a USB port that can be plugged into a Macintosh and programmed.
 * The USB connector on the Buffybot was the wrong version - one normally used on the computer end, and not on the programmable device.
