Adam (Buffy the Vampire Slayer)
Adam is a fictional character in the television show Buffy the Vampire Slayer, played by George Hertzberg.
Adam was a creation of Maggie Walsh of the Initiative. He was half human and half demon, and was to be the perfect organism. He was created in Lab 314, and his first act was to kill Maggie with a retractable stabbing weapon inside one of his arms. He killed children and demons, in order to get an understanding of biology, and was quite smart.
Spike worked for Adam for a short period of time, to help Adam stop the Slayer with an idea he got from the Beatles. Luckily for the Scooby Gang, the plan failed. Adam does not need to eat, because he has a uranium source. He is aware of every aspect of himself, and is immune to universe-changing spells.
He considers himself a brother to Riley Finn, because Maggie Walsh experimented on both of them to make them perfect lifeforms. Adam is defeated when Buffy, Willow Rosenberg, Xander Harris, and Rupert Giles combine together to make Buffy extremely powerful, and she rips out Adam's spine.
