Devil Summoner: Book of Dark and Book of Light
King Frost (called King Icy) rules over Frostville and the Ice Temple. King Frost is obtained by ranking up a Jack Frost ten times, by fusing ten consecutive Jack Frosts together. Since ranking up is not available in Devil Children: Book of Light, the only way for Jin to obtain a King Frost is through link trade.

Persona 3 FES
King Frost appears in Persona 3 as a special Persona. In order to fuse him, you have to obtain the "Sugar Key" item by completing Elizabeth's request #22

Persona 4

 * Fusion: Lilim (Devil Arcana) + Anzu (Hierophant)

Other Uses
"King Frost" is also the name of an ice-based Fusion Spell in Persona 2: Eternal Punishment; see List of Persona 2: Eternal Punishment Fusion Spells for details.
