Grüß vom Krampus!
This demonic character travels around with St. Nick in Alpine countries. He carries off naughty children to eat for Christmas dinner.

I think of Krampus as the indie rock star of traditional Christmas characters. He’s weird and awesome, but he’s never been popular in mainstream American culture, despite our high percentage of families with Germanic heritage. Still, he enjoys just enough cult infamy to appear on the Venture Brothers, and in the occasional underground comic.
