Satan (Touched By An Angel)

Satan has appeared as an antagonist in the TV series "Touched By An Angel" and often took the form of human beings so as to try and tempt people from the path of God - his efforts were opposed by the angelic heroes of the series, who often had to help people regain faith in order to ward of Satan's influence.

Although the majority of the series was based on personal struggles rather than supernatural threat a few episodes did show Satan to be the main instigator of evil - such as when he tried to corrupt a group of religious people into adopting a racist doctrine via disguising himself as a preacher.

Satan, by his very nature, could also be argued to be involved behind the scenes in every one of the series conflicts or tragedies - though he only appeared personally in a few episodes.
