The Ice King (formerly Simon Petrikov) is the main antagonist (often unintentionally) of Adventure Time. His typical misdeed is to kidnap a princess and force her to marry him, which Finn and Jake foil every time. As his name suggests, Ice King is also his title, announcing himself as King of Ice. He rules the Ice Kingdom. His Ice Powers are contained in his crown, and he is therefore powerless without it. His crown is also the cause of his loss of sanity, his unusual skin color, goblin-like nose, white eyes and beard.
