Favorite Christmas creatures and cold-themed characters for RPGs?

[LegendaryGames]

Does anyone ever use holiday-themed creatures or characters in their game? Obviously we've got our classic cold-based monsters, but in thinking about the upcoming Krampus movie or something like Narnia or even Frozen puts me in mind of the possibilities of building out a more robust Christmas or winter-themed scenario or expanding the range of cold-themed characters drawing from other media to use them in RPG.

Who are some of your favorite Christmas creature or cold-themed character from RPGs, books, movies, TV, fiction, comics, or anywhere else?

Frost worms or remorhazes?
Frost giants or white dragons?
The Awgwas from the Life and Adventures of Santa Claus?
Mr. Freeze or Captain Cold?
Elsa from Frozen or Jadis the White Witch from Narnia?
The Abominable Snowman or Yukon Cornelius?
Captain Cold or Snow-Miser?
The Winter Warlock, the White Worm from RE Howard, or the White Walkers of George RR Martin?

There are a lot of options, but I who could make a really cool (pun intended) addition to an RPG? Thoughts?

White dragons are definitely my favorite dragon (so much that I have a tattoo of "winter dragon" in Greyhawk runes).

I used a snow golem in an adventure once, taken from a Dragon magazine April fools issue. The one munchkin was indignant at fighting it, but I got a hoot out of it.

“The Coming of the White Worm” by Clark Ashton Smith is a great eerie fantasy tale involving a floating iceberg and residing demigod that brings unnatural cold wherever it goes.
