Ice King

"I know my mind is changing... but I'm already too far gone to know what to do. I want people to know that... if I do things that... if I do things that hurt anyone, please, please forgive me."

Simon Petrikov, briefly known as Ice King, is a major character conceived to be, but no longer acting as the main antagonist of Adventure Time. Originally depicted as a two-dimensional, humorously over-the-top villain trying to kidnap Princess Bubblegum 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, suffering from loneliness and memory loss. Later seasons unveil his tragic backstory, revealing he was once a good human named Simon Petrikov who lost his mind, memories and loved ones due to the magic crown giving him his ice powers.

In “Come Along With Me," Ice King is permanently reverted back to Simon after being digested by GOLB.

History
Sometime before the Mushroom War, Ice King was a normal, olive-skinned, dark-haired human named Simon Petrikov who was studying to be an (a specialist in the knowledge of ancient artifacts). He had a young fiancée named Betty, whom he referred to as his "princess" and loved dearly.

In "I Remember You," it is revealed that Ice King was a Professor of Archaeology and had discovered the ancient text of heroes, the Enchiridion, during an expedition to the mountain range. This is shown in a newspaper clipping that Marceline shows him in the episode "I Remember You." The newspaper heading reads, "Simon Petrikov Unearths Ancient Treasure," and was written by the journalist Bruce Guese.

At some point in his career, he purchased a strange jeweled crown from an old dock worker in Northern. After bringing the crown home, he put it on his head to make Betty laugh, but the crown caused him to black out and experience odd visions. He "fought with [the visions]… shouted at them until [he] realized it wasn't real—it was the crown."

Simon had no recollection of what he had said or done while wearing the crown, though it was enough to frighten away his fiancée. Simon never heard or saw Betty ever again and began to record himself on VHS tape so people would know his story. As time passed, Simon began to lose his mind as he began to wear the crown, deteriorating in both mind and body over the years into his current state. His condition worsened after his fiancée Betty was spirited into his future, which played a role in his subconscious need for princesses. As his mind and body became further twisted by the crown, Simon thought himself "too far gone" to find an escape from its influence, though he hoped that he could one day regain his sanity enough so that Betty, his "princess," would come back and love him again. He is no longer considered a human; the power of the crown not only twisted his mind but his body as well. His species/race was Wizard according to the writers.

Simon was also Marceline's "beloved friend" and guardian before eventually abandoning her. Around the time of the Mushroom War and before losing his sanity, he found a young Marceline crying in the wreckage. He gave her a stuffed doll from a toy shop destroyed in the conflict to comfort her. This toy would eventually become Marceline's most precious possession, Hambo, which she would keep and cherish until it was sold to Maja the Sky Witch by her ex-boyfriend, Ash. Marceline described Hambo to Ash as her "favorite thing in the world." She was seen alone with a worn-out version of the stuffed toy when Finn and Jake visited her memories in "Memory of a Memory," possibly several years after Simon gave it to her. In "Sky Witch," Marceline is reunited with Hambo after Princess Bubblegum managed to swap it with Maja in exchange for the shirt Marceline gave her. Simon ultimately abandoned Marceline at the same time as the filming of his final video diary, fearing for her safety at what he was becoming.

It could be implied that the crown he wore only sought to protect him. It taught him the secrets of the "ice and snow," so he would survive the Mushroom War, as it did for Farmworld Finn in "Finn the Human." However, in the same episode, Farmworld Finn mentioned the crown's "promise of power," implying the crown's seductive nature and negative influence.

As many years passed, Simon became disassociated from his original identity to the point that his only reaction to watching a video of his past was an embarrassment at the idea of having once worn glasses. Further proof of his dissociation is shown in "What Have You Done?" when he responds to Jake's accusation of him stealing the crown with, "I didn't steal it. I made that item! Made it with the magic that I stole!" When others refer to him as "Simon" within earshot, he is generally confused or ignores it.

In the series finale "Come Along With Me" Betty, King Man and Maja summoned GOLB to Ooo. Betty had linked herself with Maja with the goal of harnessing the power of GOLB. King Man told Ice King that he is the only one who can stop her. Ice King compared King Man's instruction to reason with her to "fan-fiction". and began singing "Oh, Fionna" to her, which caused her to awaken and madly berate him for opposing her when she was almost "successful" in using GOLB's power to cure him. Her powerful emotions connected to Maja causes the latter to explode, blasting Ice King and Betty into GOLB's mouth with Finn jumping in after them.

While inside GOLB's "stomach" (along with Finn), Betty and Simon were digested and reverted back to their sane and non-magical forms, with the two completely reunited, with Simon now remembering Betty. Reunited once again, Simon and Betty embrace each other as the space they are trapped in begins to shrink.

Later on, the friends of Finn and Jake sing the "Time Adventure" song, allowing Simon and Finn escape from inside GOLB, although Betty decides to stay behind as a sacrifice and use the Ice crown (which was restored to its essential form, granting its wearer their deepest, truest wish) to wish GOLB out of existence. When this doesn't work, she wishes instead that Simon is protected at all costs. As a result, Betty is fused with GOLB and the two become one singular entity. Devastated at Betty's decision, Simon cries out for her as the new GOLB leaves the planet through another portal, and is comforted by Marceline. Before the portal closes, the Ice Crown falls to the ground. Gunter decides to wear it, fuses with it and is transformed into Ice Thing after wishing to be Ice King.

Simon is later seen in Prismo's Time Room, seemingly wishing Betty back, only to have a similar result to when King Man wished to bring Margles back.

Simon is last seen in Marceline's house, making popcorn and spending time with Marceline, Princess Bubblegum, Peppermint Butler, Ice Thing, and Turtle Princess. He is shown to be smiling, implying that he has moved on with Betty's sacrifice.

Characteristics
As the Ice King, Simon Petrikov's skin turned light blue, his nose became pointy and long, his eyes and hair turned white, he grew a full beard, and his body temperature dwindled to an unnatural low of 30 °C, or 86 °F (normal human body temperature is 37 °C or 98.6 °F). His ice-based magic abilities come from a magical crown he wears, which directly causes his insanity.

Personality
Simon is 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, is 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. In "Come Along With Me" his optimism and courage is shown when he comforts Finn wisely telling him that no one gets to chose how they "go out" or die and at least they were together before being rescued.

Although Simon is characterized by these traits, Ice King's personality is completely the opposite. 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 the 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 a 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, 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 this fails 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 is all he really wants, though 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.

Physical appearance
Simon Petrikov is a human male, with olive skin and dark brown hair. He prefers to wear a dark suit with a red bow tie and his trademark blue eyeglasses. Before his curse, Simon had dark eyes, similar to Finn's, but afterward, his eyes turned white and remained so to the present day.

As Ice King, Simon was a blue-skinned, elderly man with unusually pointy fingers, pointy toes, sharp teeth, and a long, goblin-like nose. He wore a dark blue tunic and had a lengthy white beard that covered most of his body. Typically, the Ice King's weight varied in different episodes. Although his robe gave him the appearance of a fat and small/short man, Ice King's body was in fact exceptionally thin and tall. In "What is Life?," he is seen without his robe, and it is revealed that he sometimes looks short because he usually slouches. It was also revealed that Ice King doesn't have proper underwear. In "What Have You Done?," Ice King revealed that he is on a diet. However, in "I Remember You," "Bad Little Boy," and "Princess Potluck" he was shown to be fatter than usual. Confusingly, his regular emaciated state is shown again in "Mystery Dungeon" and "A Glitch is a Glitch." Pendleton Ward explained in the commentary for "Loyalty to the King" on the Season 2 DVD set that Ice King frequently diets, but binges on food when depressed and regains weight.

Ice King was rarely seen without his crown; without it he is powerless, and he is revealed to be balding with a tuft of white hair atop his head. The only times he has been seen in shoes was when he was working out before Slime Princess came to talk to him in "Loyalty to the King" and while playing basketball in "Simon and Marcy." Ice king had no visible ears when his beard/hair was removed in "Loyalty to the King" and "Mystery Dungeon."

Powers and abilities

 * CaringCircularArctichare.gif Ice King's crown bestowed upon him numerous powers in exchange for his sanity, most of which involved ice and snow. He can cast ice lightning to freeze or strike targets and can summon blizzards at will to cover the land in snow. He is also capable of creating various weapons or structures out of ice. He can also animate beings of ice and snow, like the Ice-o-pede and snowman soldiers.
 * Tumblr_mr4likys5D1qcwpypo1_400.gif could sense when someone is tampering with the snow and/or ice around the Ice Kingdom. However, it is not known if he can use this ability with snow outside of the Ice Kingdom.
 * EvenInexperiencedFunnelweaverspider-size_restricted.gifde of cryokinesis, the Ice King is also able to fly by using his beard, parting and flapping it like a pair of wings to stay aloft.
 * He could withstand high temperatures (possibly due to his own low body temperature), as seen when he stayed in the Fire Kingdom without a heat suit or flame shield.
 * The Ice King's nose lengthened when he was near or wearing the crown, and shortened whenever he was far from it.
 * The Ice King was shown to be able to take people to his "Imagination Zone" where he was able to create illusions. He uses this power to try to convince Neptr to join him with the promise of princesses.
 * He also has a power called Wizard Eyes, which makes him see strange things and puts him at risk, and he is not fully conscious while he uses this power. In "Beyond this Earthly Realm," it is revealed that his Wizard Eyes allowed him to see into the Spirit World, explaining that the freaky creatures surrounding him were spirits like Finn when he is transported to the Spirit World. In "The Empress Eyes", he seemed to possess immunity to the Empress's hypnotic abilities.
 * The Ice King's crown also prolonged his life and preserved him for at least a millennia.
 * In "The Chamber of Frozen Blades," the Ice King is shown to have studied the Ice Ninja art of Fridjitzu, and that his sanctum is filled with all sorts of ninja-esque weaponry and memorabilia.
 * Ice King's Drum Set.png Ice King has shown to be very skilled at the drums, once demonstrating a drum solo, and owned two drum sets, one of which was a green one with "#1 Babe" across the front. The set consisted of a bass drum, a floor tom, a snare, a crash cymbal, a ride cymbal, and a hi-hat. His other drum set, a red one, was in terrible shape and smashed to pieces in a corner of his castle. He could also play the keyboard fairly decently. The fact that he had so many instruments lying around his castle indicates that he had a fair amount of musical ability. Also, in "Simon & Marcy," Simon shows that he sings songs to entertain Marcy, who says his songs are "so good." His drumsticks can also be seen in the side pocket of his backpack in any post-apocalyptic flashback.
 * The Ice King also had the Demonic Wishing Eye and the Ghost pouch. The Demonic Wishing Eye's powers were shown in "Reign of Gunters" when Gunther used it to (temporarily) conquer Ooo.

Weaknesses

 * The Ice King's powers and abilities are directly tied to the crown, however, and its removal will strip him of all his abilities until he puts it back on.
 * Extreme heat/humidity could also negate his powers. This was seen when his powers became weaker in a heated chamber in a hidden dungeon, and despite having a moat of water, the humidity in the area made it impossible for the Ice King to convert any of the ambient water or vapor into ice or frost.

Trivia

 * -|Notes=
 * Princess Bubblegum has striking similarities with Simon Petrikov's fiancée Betty, as their heights, faces and hairstyles are similar, they both have pink skin, and they both are known to work in science. This might explain why Ice King likes Princess Bubblegum more so than the other princesses, and it may also suggest that some of Petrikov's desires have remained even after he lost his sanity and became the Ice King.
 * This might be a reference to the fact that Bubblegum's preliminary name was Bettie, although it's spelled differently.
 * It is possible that Ice King was motivated to steal princesses partly by the fact that as Simon, he called Betty his "princess", and some subconscious part of his mind thought that if he stole princesses and forced them to marry him, he could find the same love Simon once had with Betty. This is not confirmed because it isn't known if Simon called Betty his princess before putting on the crown.
 * Simon, who was an archaeologist, is seen holding the Enchiridion, in the pictures above.
 * Ice King has a tattoo of a penguin on his right buttock, as seen in the episode "Prisoners of Love" during his dream sequence.
 * Ricardio is the Ice King's heart; made sentient by magic. Though the power of the crown can keep him alive when Ricardio leaves his body, the Ice King is left extremely weak without a heart.
 * In the episode "Lady & Peebles," Princess Bubblegum builds an artificial heart for the Ice King- made out of Ricardio's sinews, toffee, and maracas. The replacement is presumably permanent, as Ricardio runs away and his last appearance occurs in come along with me as a cameo in the background.
 * His cut-out has Ricardio sticking out under his beard.
 * Ice King has a computer which he uses to play video games, as seen in "What is Life?" and to make rudimentary drawings of himself with princesses, as seen in "The Chamber of Frozen Blades." In "A Glitch is a Glitch," he uses his computer to create a virus to delete the entire universe, save him and Princess Bubblegum. However, he was stopped by Finn and Jake who saved the day through a reenactment of a disgusting video they watched at the beginning of the episode.
 * He is currently the only main character in the series whose parents have not yet been introduced.
 * In "Mortal Folly," when Ice King tried to lift the latch on a window in order to see Princess Bubblegum, he used a small card that has the word "Wizard" printed on it.
 * He sometimes falls asleep with his eyes open, as seen in "Still."
 * As Simon Petrikov, a Scientific Parasite is visible in his coat pocket. This had led fans to believe that Simon may perhaps be brilliant in his profession of Archaeology.
 * Ice King is older than Marceline by precisely forty years, as seen in the episode "I Remember You" and clarified further in "Simon & Marcy."
 * Ice King loves filling his bathtub up with milk and sitting in it like he is a magic angel. This is revealed in a slowed-down portion of Ice King's tapes in the episode "Holly Jolly Secrets Part I."
 * It seems that the Ice King will steal any adult female so long as she has the word "Princess" in her name. This is shown in "The Chamber of Frozen Blades," in which he kidnaps Doctor Princess, even though "Princess" is merely her surname.
 * Ice King's favorite princesses, as he revealed in "Princess Monster Wife," are Princess Bubblegum, Muscle Princess, Skeleton Princess, Turtle Princess, Hot Dog Princess, Wildberry Princess, Elbow Princess, Slime Princess, Lumpy Space Princess, and (not an actual princess) Doctor Princess.
 * It is revealed in "Little Dude" that Ice King sometimes sleeps on Finn and Jake's roof.
 * Simon may have been a fan of the classic TV show Cheers, as he reenacted the iconic "Norm!" greeting in "Simon & Marcy" and even sang an abridged version of the theme song.
 * Ice King is similar to the Teen Titans character Mumbo. They both have blue skin and white hair, they are both voiced by Tom Kenny, and they are both magic users with similar origins.
 * Ice King is also similar to the Winter Warlock from . They both have a long nose, sharp teeth, beard and wear robes, they both control winter and snow, live on mountains, and they both appear to be evil, but end up not being so bad.
 * He is an avid fan of Marceline's music. His favorite song may be Fry Song because he did a cover twice.
 * In the special feature of the DVD Adventure Time: My Two Favorite People, "Little Did You Know," Ricardio's "species" is shown to be a human heart, meaning that Ice King is still genetically human.
 * Ice King can hide items under his beard, as seen in "Hitman" and "I Remember You."
 * Ice King is slightly similar to Gollum in Tolkien's  and The Hobbit. Ice King refers to Betty as "princess," whereas Gollum refers to his ring as "precious." The crown which he purchased made him insane while the One Ring had corrupted Gollum. Also, his past from when he was Simon Petrikov is similar to Gollum's from when he was known as a Hobbit by the name of Smeagol.
 * It was stated by Pen Ward that the Ice King's body weight fluctuates with his mood changes.
 * Simon Petrikov's design and characteristics share many similarities with those of Milo Thatch from "Atlantis: The Lost Empire." Both Simon and Milo are intellectuals fascinated with artifacts and history and both are driven to achieve their goals for the sake of knowledge. It is assumed that Simon Petrikov was enthused by his career choices (Archaeology and Anthropology) while Milo specialized proudly in Cartography and Linguistics. Simon's red bowtie and yellow undershirt are almost identical to Milo's bowtie and shirt at the start of "Atlantis." They both wear glasses (although Milo's are large and clear-lensed and Simon's are small and blue-lensed) and both undertake trips to foreign lands that change their lives forever. Even the discovery and significance of the Enchiridion (for Simon) and the Shepherd's Journal (for Milo) draw shocking parallels.
 * Ricardio seems to know about Ice King's previous life, being his former heart, and this seems to be true because in the episode "Lady & Peebles" when Ice King asks for a hug, Ricardio steps on him and says "Silence, Simon!"
 * Like the most characters Ice King is ambidextrous. In "Mystery Dungeon", he is shown to be able to write with either hand in separate scenes.
 * Ice King has many characteristics similar to Doctor Two-Brains from WordGirl.
 * Both have something on their head that turned them insane (Simon with his crown, Steven with his helmet).
 * Both have a photograph of their original selves wearing a green sweater and standing next to a woman.
 * Both had their hair turned white and their skin change in pigment upon going insane.
 * Both initially had brown hair.
 * Both are voiced by Tom Kenny.
 * Both were previously friends with one of the protagonists (Simon and Marceline, Steven and WordGirl).
 * Simon might be of Eastern European origin, due to his last name.
 * It is theorized that he is Russian, because Petrikov is a Russian name.
 * Further more supporting this theory is that there is a Dutch brand of Vodka called Petrikov, Vodka is a Russian alcohol.
 * -|Storyline analysis=
 * In "Fionna and Cake," when Cake put on the Ice Queen's tiara, Fionna knocks it off, yelling, "Take that off! You might catch her crazy!" As "Holly Jolly Secrets" has revealed, the power of the Ice King's crown caused him to lose his sanity. Since Fionna and Cake and their universe are fan fiction written by the Ice King, this shows he knows to some extent, at least subconsciously, that the crown can endanger its wearer's sanity.
 * In "I Remember You," on the newspaper clipping that Marceline shows the Ice King, we can see Simon getting out of what appears to be an old black Plymouth 4-door, holding the Enchiridion underneath his arm: this story reports that he was the archaeologist who found the legendary book. Betty can be seen sitting in the occupant's side.
 * Over the same newspaper clipping, there are written lyrics to "Oh, Bubblegum." Ice King stated he wrote the lyrics down on that paper. In a parallel of this, the picture of young Marceline has the notes that became the lyrics of the song "Remember You" on the back, suggesting Simon wrote those just before he lost his identity, to apologize to Marceline when she would read them in the future.
 * Even though he has been changed by the crown, Ice King still shows signs that some vestiges of his former self remain. This can be seen in certain things he says and does. For example, in "I Remember You" when he finds his old scrap book filled with poignant reminders of the man he once was and his shared past with Marceline, he absentmindedly describes the pages as "wet with tears." The implication is that during a recent moment of lucidity he was crying over them and has since forgotten doing so. He brings the diary entries with him as inspirational material for the song he wants Marceline to help him compose.
 * 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"; his only reaction to the tapes was shame at the fact that he previously wore glasses. This may suggest that the crown tries to suppress all living memory of Simon Petrikov in Ice King's mind.
 * Ice King seems to act more contemplative, reasonable and conscious to others when he removes his crown for a long period of time. His clearer thinking could be due to an absence of the crown's influence. In the episode "Holly Jolly Secrets Part I," Ice King is shown (in his secret tapes) without his crown on, looking sad and more serious than normal, talking about his "innermost thoughts." He begins to say "As you can see, I'm not wearing my -" several times before being interrupted by his penguin. It can be assumed he was referring to his missing crown, and he says that he is more contemplative than normal. Another good example is the episode "The Party's Over, Isla de Señorita" during which the titular character's entire encounter with the Ice King takes place while he's not wearing the crown. After much conversation between the two, she ends up making a tough, life-altering decision, and says she would never have been able to do so without the advice of her "emotionally mature friend, Ice King."
 * In the episode "What Have You Done?," he said that he got his crown through the magic that he stole. Later on in "Holly Jolly Secrets Part II" it is revealed that he purchased the crown in Scandinavia. This dissociation is related to the true origins of the crown, as in "Evergreen", it is revealed that the crown turns its wearer into "Urgence Evergreen", its creator, who stole the magical jewels from Magwood in order to create it.
 * In "Mortal Recoil," Ice King exits the scene when Bubblegum is reduced from 18 to 13 years old. In "I Remember You," Ice King states in his song "Oh, Bubblegum" that he thinks Flame Princess (who is 15) is merely "okay." This indicates a lack of interest in younger-aged princesses.
 * -|Appearances in other media=
 * Ice King is a quest-objective character in FusionFall, and his crown is a wearable item.
 * On New Year's Eve 2010, there was an Adventure Time marathon, and it featured bumpers with the Ice King.
 * Ice King is one of the bosses in Adventure Time: Explore the Dungeon Because I DON’T KNOW!. Once you defeat him, you can play as him.
