|~ -Ice King to Gunter the Penguin|
|“||After purchasing this crown from an old dock worker in northern Scandinavia, I brought it home and excitedly showed my fiancée Betty, and jokingly put it on my head just for a laugh or something, and that's when it started. The visions, I fought with them. Shouted at them until I realized it wasn't real—it was the crown! I quickly took it off, and saw my fiancée in front of me, looking at me with such contempt. What had I said? What had I done when I wore this crown? All I know is I never saw Betty again.||„|
|~ Simon Petrikov's first tape recording documenting his gradual transformation into the Ice King|
Simon Petrikov (formerly known as the Ice King) is a major character as well as the secondary antagonist of the Cartoon Network series Adventure Time.
Earlier in the series he started out as a villain, but later on in the series, he occasionally proves himself to be a valuable ally.
He was voiced by Tom Kenny who also voiced Raimundo Pedrosa in Xiaolin Showdown, Ryan Sumozski in Clarence, The Mayor of Townsville in The Powerpuff Girls, In the Japanese dub from the series, he was voiced by Takeshi Maruyama.
Ice King, aka Simon Petrikov is a unruly monarch from the Ice Kingdom. Once a close friend or even a father-figure of Marceline's, he's spent years pestering her. She says that she tolerates his presence because she loves him unconditionally, and remains one of the few characters to bestow compassion upon him to date. In truth, these are but the remnants of a pre-apocalypse professor of archaeology and antique enthusiast once named Simon Petrikov, before he was driven insane and transformed by the arcane forces of ice and snow within a crown he bought. The subsequent bouts of madness estranged him from his beloved fiance, Betty, and his nickname for her, "princess", was warped by time and insanity into his compulsion to kidnap and marry princesses in present day Land of Ooo.
Though (in earlier episodes) Ice King was portrayed as disagreeable and short-tempered due to his main antagonistic role, he is merely a nuisance and "isn't usually a serious threat," according to Princess Bubblegum. In later episodes, due to no longer acting as a main antagonist, he is portrayed as more easy-going and having a sense of humor, particularly due to Ice King considering Finn and Jake his "friends" after the events of "What Have You Done?"
The Ice King is misunderstood, lonely, and only hopes of marrying a princess. He has been labeled a "sociopath" by the Cosmic Owl, though his personality seems more akin to a person with narcissistic personality disorder, as he still feels humiliation and guilt. Due to his poor social skills, enduring short attention span and arrogant nature, Ice King is unable to attract any of his prisoners and often resorts to a forced marriage instead of the loving relationship he desires. However, he can be a loving and selfless person as revealed in "Princess Monster Wife." Aside from Gunter, his other penguin guards, and numerous ice creatures, Ice King has few other friends and expresses a continual zeal to spend time with anyone who will tolerate his company, especially his frenemies, Finn and Jake. In "The Eyes," he takes on the disguise of a horse to spy on Finn and Jake in an effort to learn how to be happy, but fails that as well.
Despite Ice King's more antagonistic role, he plays the part of a protagonist in "Mortal Recoil," as he helps Finn and Jake defeat Princess Bubblegum by freezing her Lich-possessed body. In the mini-episode, "The Wand," he actually helps Finn and Jake regardless of the fact that Finn said to "sacrifice" himself, but unbeknownst of the fact that it also changed his face. Ice King is harmless in nature, and only kidnaps princesses and steals out of desperation. However, in the episode "Loyalty to the King," when he does have the opportunity to marry many princesses, he secretly plots to make an elite army of wives to take over the world with. His misunderstood intentions may either be in question or may just stem from his lunacy. His crown has made him insane over the years, affecting his social skills, causing him to unintentionally do bad things. Friendship and companionship are all he really wants, even though he goes about it the wrong way. Due to the insanity brought by wearing the crown, Ice King seems to have limited memory. This was first seen in "I Remember You," where he does not seem to remember his past as Simon Petrikov, even though he saw the history (after he found the crown) in "Holly Jolly Secrets Part II." Later on, he does not remember who Neptr is, even though he was the one that wanted Neptr to accept as his father in Neptr's debut, "What is Life?" and even confuses him with BMO, as seen in the events of "Mystery Dungeon."
Ice King seems to find his happiness in his own Imagination Zone, and it is clear that he would rather live in his Imagination Zone than in the real world. In "Fionna and Cake," he is shown reading his gender-swapped fan fiction to Finn and Jake, based on the events and characters in the actual world. He is shown to cherish his fan fiction characters more than the real-life characters, and in "Mystery Dungeon" he tries to bring the characters to life, but he fails. In "Bad Little Boy," it is revealed that he had made ice sculptures of Fionna and Cake along with writing many other fan-fic stories. Although Ice King is characterized by these traits, Simon's personality is completely the opposite: he was known for his intelligence, kindness, and self-sacrifice. From the information given in "Holly Jolly Secrets Part II," Simon was a deeply committed and loving fiancé (to Betty). He proved to be the same way as a watchful guardian over young Marceline during the aftermath of the Mushroom War. Even when they were in great danger, Simon struggled to keep Marceline happy and helped her to always see the best of their situation.
He took on a very responsible role in Marceline's life, by not only protecting her and keeping her healthy, but also by teaching her right from wrong and keeping her spirits high (as seen in "Simon & Marcy"). Simon, as a rule, was known for being optimistic even at the worst of times and it is clearly one of Simon's most notable attributes. Even while being saddled with a great burden, Simon fought an apocalyptic world while fighting the omnipotent influence of the Ice Crown. Some of Simon's innermost thoughts and fears of his inevitable madness were revealed in messages left to Marceline revealed in "I Remember You." Simon agonized over abandoning Marceline in a dangerous world due to his deteriorating sanity. However, Simon, nearing the very end of his humanity feared for his own life, worried that as the crown took him from Marceline, no one would be able to "save him." His vulnerability as a human was most evident just before he permanently became the Ice King.
