Satan is a recurring character on the show South Park. Like nearly all characters on the show he is creators Matt Stone and Trey Parker's exaggerated and creative take on the original idea. Satan was first introduced as the ultimate adversary of Jesus Christ in the final battle between good and evil. In the battle Satan threw the fight having been the sole person to bet on Jesus's victory and thus winning the money of every single person in South Park.
Satan appeared again in the film South Park: Bigger, Longer & Uncut. He functions as the main antagonist, later anti-hero of the movie along with his former lover Saddam Hussein who was egging him on to destroy the world. At the end of the movie, Satan realizes Saddam was just using him and pushing him into destroying the world when all Satan originally wanted was to just leave hell so he could live happily on earth instead. Satan turns against Saddam during the movie's finale and returns to Hell to repay Kenny McCormick for making him realize the truth about himself. Ever since the movie Satan has been portrayed as a comic relief of the show and a normal person who just happens to be the king of hell. Satan has been shown to sometimes be immature but kind and empathetic though he no longer wishes to harm the people of earth he has never given up his long term goals of conquering heaven. Oddly enough Satan is still on friendly terms with God.
