Jack Frost

Jack Frost is a recurring ice spirit and mascot-like demon in the Shin Megami Tensei series. Based loosely on winter folklore, he appears across many games as an enemy, recruitable ally, fusion material, and representative of the wider demon system.

Jack Frost across Shin Megami Tensei

Cheerful, mischievous, and known for ending phrases with "hee-ho," Jack Frost is usually less threatening in personality than many demons around him. His exact allegiance and narrative role change between titles.

Ice magic, "hee-ho," and multiple demon variants

Jack Frost specializes in ice magic such as Bufu while often being weak to fire. Variants including Black Frost, King Frost, and regional forms expand the concept, so individual versions should be distinguished by game and alignment.
