Jack Frost is the nasty spirit of winter and the main antagonist in The Santa Clause 3: The Escape Clause.
He was portrayed by Martin Short.
Though he is a member of the Council of Legendary Figures, Jack Frost was extremely jealous of the current Santa Claus (Scott Calvin) because of his popularity with little children and even desired his own holiday called "Frostmas" (even he also obnoxiously conducted ridiculous ideas of his own other holidays, "Frostgiving", the "Frost of July" and "Frosthog Day".). The Council have taken disciplinary action against Frost and charged him with 273 counts of crime against the Legendary Figures ethical code of conduct including attempted upstaging of Santa Claus, freezing of a volcano in Hawaii and snowing in the Amazon, and frosting of all Mexico which sends all of the geese north for the winter (with 270 cut-out figures of himself wearing his Frostmas sash found in every shopping mall all over the Northwest as evidence).
And so after causing trouble in the North Pole, he finally stole his magic snow globe, tricked him to active the classified Escape Clause by saying "I wish I have never been Santa at all", and went 12 years back in time to the year 1994 where Santa accidentally killed the original Kris Kringle. Frost put on the coat, took over the North Pole, and turned it into a Frostmas-themed amusement park named "North Pole Resort".
After Scott Calvin undo the wrongful changes and returned the North Pole back to normal, Jack Frost, who quickly arrested by the North Pole's Elfficers for freezing both Dr. Neil Miller and Charlie Calvin's mother Laura, later reverted to good when a warm hug from Scott Calvin's niece Lucy transformed him, unfroze her parents, and made him want even more hugs.
Jack Frost was extremely manipulative, cunning, and evil for freezing Lucy's parents, or freezing Hawaii, and causing mischief. Jack was referred to as willful, malicious, and obstreperous, which he referred to as "skillful and delicious". He was able to get Santa to give up his role and take over the North Pole, and reverse time. However, he turned good at the film's end after the kind, young Lucy warms his cold heart with a hug.

Excuse me. Did you just accuse me of being skillful and delicious? Guilty as charged.

You can manipulate time, but you can't grow hair!
~ Jack Frost insulting Father Time
You get the soda cans, and you get the TV specials, the postage stamps and the billboards and the beautiful adoring wife, and the army of toy-building yes-men. What do I get? A few runny noses and some dead citrus.

You're not Santa anymore. You're just the guy who smells like a cookie."
