Santa Claus
Santa Claus, also known as Saint Nicholas, Kris Kringle, Father Christmas, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring gifts to the homes of well-behaved ("good" or "nice") children on Christmas Eve (24 December) and the early morning hours of Christmas Day (25 December). The modern Santa Claus grew out of traditions surrounding the historical Saint Nicholas (a fourth-century Greek bishop and gift-giver of Myra), the British figure of Father Christmas and the Dutch figure of "Sinterklaas" (himself also based on Saint Nicholas). Some maintain Santa Claus also absorbed elements of the Germanic god Wodan, who was associated with the pagan midwinter event of Yule and led the Wild Hunt, a ghostly procession through the sky.
Christmas Evil
On Christmas Eve, while gluing a Santa beard to his face, he enters a fugue state that has him convinced to truly be Santa Claus. Donned in his Santa suit, Harry starts doing his rounds on the van that he decorated with a sleigh picture, and that he believes to have been trained by Santa Claus's reindeer. He first sneaks into his brother's home and delivers toys for his nephews; then leaves a bagful of dirt at the doorstep of "bad boy" Moss Garcia. Later, Harry drops off toys at the hospital, where he is greeted cheerfully by the staff.
