Jack Frost is a lurking side-villain over the course of the story, who shall have a bigger part in future appearances. He is an old arch-enemy of Santa-Man & was the reason for his departure as a superhero. He should have a deep & evil voice, while being able to sound very calm at times, for some reason I always picture him as being british -- sounding much like "Loki" from the MCU -- if you recieve the role, you shall expect to return for more films as the character.
