Jack Frost is the personification of frost, ice, snow, sleet, and freezing cold weather, a variant of Old Man Winter 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. Starting in late 19th century literature, more filled-out characterizations of Jack Frost have made him into a sprite-like character. He sometimes appears as a sinister mischief maker or as a hero.
Jack Frost is a winter spirit. The character name itself has spin-offed many characters who assumed the name in various comics:
Marvel Comics
- Jack Frost
- Blizzard
Vertigo Comics
- Jack Frost (from the Invisibles)
- Jack Horner (from Fables)
