Shin Megami Tensei III: Nocturne
Black Frost is an optional boss in Shin Megami Tensei III: Nocturne. Hoping to become as powerful as the "Great Demon", a Jack Frost stumbles upon a Magatama. The Jack Frost proceeds to ingest the Magatama, which happens to be the Satan Magatama, which transforms him into Black Frost.

The transformed Jack Frost would later take over Ikebukuro Prison, where he freezes the whole prison and took the remaining Jack Frosts as his servant. If the Hito-Shura visits Ikebukuro Prison, Black Frost will ask the Hito-Shura as a subject to test his new found powers, and engages him to a battle. Defeating Black Frost allows the Hito-Shura to obtain the Satan Magatama.

In the expansion re-release of Shin Megami Tensei III: Nocturne, titled Shin Megami Tensei III: Nocturne Maniax (Lucifer's Call in the NA version), after defeating Black Frost, he will appear in the third Kalpa of the Labyrinth of Amala. Should the Hito-Shura speaks to him, Black Frost will inform the Hito-Shura that he believes that he would become stronger if he joins the Hito-Shura, and force his way into the Hito-Shura's demon arsenal, becoming one of the Hito-Shura's ally.
