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.
The Secret World of Santa Claus
Santa Claus is Father Christmas. (Also the main protagonist of the show). He owns a large workshop in the North Pole with his three elves. He owns a sleigh with reindeer. It is not clear how long he has been Santa Claus or how old he is but in the episode "The 12 Labours of Santa Claus" it is revealed that he has been Santa Claus for at least 100 years. Also in "The Christmas Conference" he stated they had successfully ended the 451st annual Christmas Conference, so he has apparently been in the job for a long time. He is always shown in the classic Santa outfit; a red suit, hat, pants and black boots with golden buckles.
