Santa Claus

Santa Claus, also known as Father Christmas, is a jolly man who is the spirit of Christmas. He usually resembles a rotund human male in a red coat with white trim. He has a big, bushy white beard.

He delivers presents to children on Christmas Eve, flying through the sky on a sleigh pulled by reindeer. He is aided by a workshop full of elves.

Adventures of Sonic the Hedgehog
Santa Claus has appeared in the Adventures of Sonic the Hedgehog special, Sonic Christmas Blast as a major character. He was kidnapped by Dr. Robotnik, who usurped him as "Robotniklaus". Robotnik planned to steal Christmas and rule the world. Santa apparently announced his retirement, but in truth he had been replaced by Metal Claus, a dim-witted robot who was only programmed to say things revolving around Christmas.

Robotnik held Santa captive in an ice cave in the North Pole. Sonic rescued him but it still seemed hopeless, even by his abilities, to save Christmas. However Santa recognised the Ring of Ultimate Velocity on Sonic's finger and, with Sonic's help, was able to save Christmas.

Impressed by Sonic's abilities to deliver all the presents in the world in a matter of minutes he passed his signature red cap to Sonic, trusting him to continue delivering presents on Christmas Day.

Mario & Sonic at the Olympic Winter Games
Santa Claus makes a cameo apperance in Mario & Sonic at the Olympic Winter Games as a VIP where he shows up in Dream Events during December.

Sonic the Comic
A slightly different version of the character, primarily known as Father Christmas instead of Santa Claus, made several appearances in the British series Sonic the Comic. This Father Christmas possesses incredible magical abilities, the limits of which are unknown, which include the ability to appear and disappear at will and the ability to predict the future. He is also invisible to robots.

Father Christmas first appeared to Doctor Ivo Robotnik while he was dictator of Mobius, offering him a chance to do a good deed (although Robotnik refused) and predicting that Robotnik's empire would soon fall if Robotnik did not change his ways. Father Christmas later appeared to apprehend a villainous elf named Vile Peter, who had been kidnapping children from the Emerald Hill Zone.
