Adam (Buffyverse)

"Before Adam? Not a man among us can remember." ~ Adam, after being questioned on his name prior to the experiment

 Adam was a major antagonist of the Buffy the Vampire Slayer TV series and was a Frankenstein's monster type villain who sought to spark a war between humans and demons so as to harvest the bits and pieces left over and create an army of cybernetic demon-hybrids similiar to himself - he served as the "Big Bad" of a storyarc involving a military-based organisation that was formed to combat supernatural evils but were clearly corrupt, Adam being the ultimate result of said corruption.

Despite his evil goals Adam was seen as a master of manipulation with a talent for words, so much so that he was able to get a large number of demons and vampires to work together despite the two traditionally being enemies - he was also very keen to ensure that Buffy was present when the war between humans and demons was sparked so that she would help even out the number of human to demon corpses before she was killed.
