Santa Claus, also known as Saint Nicholas, Father Christmas, Kris Kringle or simply "Santa", is one of the two main antagonists (alongside Avery Bullock) of the American Dad! series. He is the legendary and mythical figure who, in many Western cultures, brings gifts to the homes of the good children during the late evening and overnight hours of Christmas Eve, December 24 or on his Feast Day, December 6 (Saint Nicholas Day). The legend may have part of its basis in tales concerning the historical figure of gift giver Saint Nicholas.
While Saint Nicholas was originally portrayed wearing bishop's robes, in modern times, Santa Claus is generally depicted as a plump, jolly, white-bearded man wearing a red coat with white collar and cuffs, white-cuffed red trousers, and black leather belt and boots. This image became popular in the United States and Canada in the 19th century due to the significant influence of caricaturist and political cartoonist Thomas Nast. This image has been maintained and reinforced through song, radio, television, and films. In the United Kingdom and Europe, his depiction is often identical to the American Santa, but he is commonly called Father Christmas.
In "For Whom the Sleigh Bell Tolls", Steve accidentally shoots Santa with a gun Stan gave him despite Francine's objections that Steve was too young. Despite their attempt to hide the body, Santa is recovered and resuscitated by his elves and vows vengeance on the Smith's. The Smith's take refuge in a moonshiner's cabin where they fend off an attack of elves, reindeer and snowmen led by Santa until Santa's army is forced to retreat at dawn, vowing to return the next year.
