Jack Frost

Jack Frost is the main villain in Disney's The Santa Clause 3: The Escape Clause. He is the legendary figure responsible for snow, ice, and cold weather.

Role in The Santa Clause 3: The Escape Clause
Jack Frost is accused of attempting to upstage Scott Calvin in the position of Santa Clause, and is charged with 273 counts of attempted upstaging; including freezing a volcano in Hawaii, making it snow in the Amazon, frosting Mexico sending Geese north for the winter, and creating 270 cardboard cut-outs of himself which read "Merry Frostmas" and placing them in various malls throughout the North-west. The council considers suspending Frost for these actions, though Frost manages to convince them to make him do community service working for Santa instead. Santa agrees, though he tells Jack he has to listen to the elves, and makes the Head Elf Curtis his boss.

Jack helps to disguise the North Pole as Canada for the arrival of Calvin’s in-laws, and pretends that he is a mascot that will be playing Jack Frost in a parade. He tricks Curtis into telling him about the “Escape Clause”, and forms a plan to trick Scott into evoking the clause so that he can become Santa himself. Jack goes around the factory and lures the elves away, and then uses his powers to create technical problems with some of the equipment.
