Simon Petrikov, formerly known as the Ice King, is a major character in Adventure Time and deuteragonist of it's spin-off series Adventure Time: Fionna & Cake.

Originally depicted as a two-dimensional, humorously over-the-top villain trying to kidnap Princess Bubblegum and various other Princesses on a regular basis, the character's personality was subsequently expanded, revealing him to be a kind-hearted but misunderstood old man with completely twisted senses of morality and social behavior.
