Jack Frost is a sprite-like character with roots in Viking lore, where he is known as Jokul Frosti ("icicle frost"). In Britain and the United States, Jack is a variant of Old Man Winter and is held responsible for frosty weather, for nipping the nose and toes in such weather, coloring the foliage in autumn, and leaving fernlike patterns on cold windows in winter. He sometimes appears in literature, film, television, song, and video games as a sinister mischief maker.
Appearances in Christmas specials
In Frosty's Winter Wonderland, he was a mischievous sprite who was jealous of Frosty because he didn't get the attention he wanted like Frosty does. He tries to get rid of Frosty by stealing his magic hat, but after this fails, he eventually has a change of heart when he is asked to be the best man at Frosty and Crystal's wedding. This version of Jack Frost was later seen again, this time in stop-motion animation, at the end of Rudolph and Frosty's Christmas in July; here, Big Ben brings him in from South America to revive Frosty, Crystal, Chilly and Milly after they are melted by the July heat.
In Jack Frost, he is an invisible sprite that nobody can see or hear. One girl named Elisa thanked Jack Frost for saving her and wishes to see him in person. When he asked Father Winter to become human, Father Winter told him that Jack will become human permanently if he acquires the following: a house, horse, bags of gold, and a wife. He went under the name of Jack Snip the tailor. After stopping the evil Kasack king, Kubla Kraus, he got a castle, a robotic horse, and bags of gold. Unfortunately for Jack, he never got to have a wife realizing that Elisa is in love with the knight in golden armor. So by springtime, Jack turns back into an invisible winter sprite and flew back to the Kingdom of the Winter Clouds.
Under Disney, Jack Frost appeared as the antagonist of The Santa Clause 3, in which he was portrayed by Martin Short. In this film, Jack is jealous of the attention that Santa Claus receives and schemes to replace him.
