Sometime before The Great Mushroom War, the Ice King was Simon Petrikov, a young glasses-wearing human who was working to be an antiquarian. One day, he bought a crown and went to show it to his fiancee Betty, whom he dubbed 'Princess'. He put the crown on his head for a laugh, which made him do something so terrible (of which he had no memory) that Betty left him. He then begins to slowly lose his sanity and look more and more like the "Ice King". This is the FIRST APPEARANCE of this character in premium digital format.
