You missed out on Odin/Wotan the one eyed white-bearded God of the North who rides through the sky on his eight legged horse Sleipner with a sack on his back for the Yule or Wild Hunt. If you are good (and leaving some food helps) he will give you a present (custom has it in your shoes which you leave outside) , if you are bad he puts you in the sack and you have to work for a year for him in his toy factory in China.

Then there is Jingle the reindeer who visits the animals in the various Animal Crossing games on Christmas night.

And Rassilon who opens Omega's star on the feast of Rassilarium which weeps a year of good fortune to all those who have not broken any of the laws of time.

And the Gilded Yak flying on his enchanted canoe from the West Pole. Who will leave you the gift of shaving scum if you hang out soiled diapers on Yak Shaving Day.
