Jack Frost. Snowman, or legendary mascot? Jack Frost is the mascot of Atlus. He resembles a snowman, but has teeth, a tail, no nose, and wears a joker hat and shoes. His catchphrase is "Hee-Ho". He has appeared in several Atlus games, including several entries in the Shin Megami Tensei series and Jack Bros. He is a hidden character in the both the American and Japanese versions of SBK: Snowboard Kids, but has a larger role in the Japanese version.
Jack Frost has derived a family in its universe and more relatives were created since Shin Megami Tensei II. Such as King Frost, Frost 5 Senshi (warriors of justice), Ja-aku Frost (Black Frost), etc.
Jack Frost also makes a cameo appearance as a button/brooch on the clothing of the gunner class in Etrian Odyssey II, another game by Atlus.
