Jack Frost is a personification of frost and cold weather that is generally depicted as a mischievous imp-like creature, who uses his power over snow and ice to decorate winter landscapes. He can be friendly, but can also use his cold powers to kill. He is sometimes depicted as a friend of Santa Claus and sometimes depicted as his foil.
A number of public‐domain stories depict Jack Frost as being responsible for the change of leaf color in autumn. He dispatches fairies to transport a precious gift, but they waste time along the way, and so the gold and gems, which the fairies had left in the treetops, accidentally melt in the sun and change the colors of the leaves to browns, golds and reds. Jack likes the result so much he decides to do it annually.

L. Frank Baum portrays Jack Frost, the Frost King and Santa Claus as three clearly separate and distinct characters, and other writers similarly maintain distinctions at least between pairs of them, including having them interact with one another, but some writers conflate and combine them. For example, a number of public‐domain stories portray Jack Frost as a king with a palace and refer to him as King Frost. Also, Frost, or Morozko, is a Slavic god or demon who served as an antecedent to Ded Moroz, the Slavic Santa Claus, but is often portrayed as being much more like Jack Frost and, in at least one translation, is even called Jack Frost.
