"Kain is a fictional character and the titular character that appears in the Legacy of Kain series of video games. Depending on the game and its viewpoint, Kain has been either the central protagonist, or an antagonist, but in all his depictions he is an anti-hero, interested only in his own goals. The character was designed by Denis Dyack and voiced in all his appearances by Simon Templeman.
An arrogant noble murdered and revived as a vampire, Kain embarked on a crusade to kill his assassins and then be restored to human form. When he came to revere his powers, Kain turned his back on his prophesied duty and became a vampire lord ruling over the land. Kain's attentions later turned to averting his destined doom at the hands of his lieutenant Raziel. Kain's manipulations of Raziel in the hopes of changing his destiny effectively set in motion the events that make up most of the Legacy of Kain series.
The character of Kain has been positively received by critics, described as a "typical Oedipus figure" or "gnostic hero", with much praise directed at his dark portrayal in Legacy of Kain: Soul Reaver and the quality of Simon Templeman's voice acting. In 2000, Kain was ranked tenth in a Gamespot Readers' Choice poll for the top ten villains in video gaming."
