Background
Margaret finds Finn and adopts him.Added by KoolioPhoebeAs shown in "Memories of Boom Boom Mountain," Finn appears to have been abandoned in the woods during infancy. He reveals that he made "boom boom" (Finn's word for defecation) on a large leaf, fell on it, and lay there crying until Joshua and Margaret (Jake's parents) rescued him from the wilderness to raise him alongside Jake, who becomes like a brother to him (as such, Jermaine is also Finn's adoptive brother). In "Memory of a Memory," a baby Finn is seen singing a song in the bathroom of what appears to be Joshua and Margaret's house. In "Henchman," when Finn is asked about his parents, he says Jake told him that he came from a cabbage, in jest. In "Susan Strong," Finn states that he knows nothing of his human parents or any other humans.

Status as the last human
Finn is the only confirmed human in the Land of Ooo. In the episode "Her Parents," Lady Rainicorn's dad says he thought humans were extinct. This lends new significance to his title "Finn the Human," as his humanity may be unique in Ooo.

Up until "Susan Strong," Finn believes he has never met another human. Finn becomes morose and "soul-searchy" when he thinks about it. In the same episode, Finn encounters Susan Strong. Even though the other members of Susan's tribe of Hyoomans were revealed to be mutants, Susan's identity as a human or mutant is left ambiguous. In "Beautopia," it may be true that Susan is also a human, but it was not confirmed. The businessmen are also likely humans, but their minds have been damaged by being frozen for so long, they talk like zombies. They also have boils all over their face, which may also be a result of being frozen.

Other "human" characters (such as Penny, Phil or the Old Man Henchman) have been confirmed by the show's creator, Pendleton Ward, to be mutants or humanoids.|[2] |[3] According to Pendelton Ward's FAQ page |[4], even Finn is mutated in some way.

Fionna is also a human, although she was just a character in Ice King's fan fiction. Ice King was formerly a human, as shown in "Holly Jolly Secrets Part II."

Appearance and equipment
Pen, Finn's original art designAdded by Lukesav1998Finn is a 14-year-old|[5] human. He has several missing teeth because he bites trees and rocks among other things.|[6]

Although his eyes typically lack detail and appear as small black dots due to a minor mutation,|[7] they are shown to have color in the episode "The Enchiridion!," when Finn is tried by the Dark Magician. His left eye is green while his right eye is blue, characteristic of the genetic condition heterochromia. (However, as stated by lead character designer Andy Ristaino on Formspring, "That was a special occasion. The heterochromatic effect was a byproduct of him being hypnotized by that guardian dude." Andy confirmed that Finn's eyes are blue.|[8]

Hair
Finn has blonde hair which is first seen in "To Cut a Woman's Hair," where Finn removed his hat, and long, golden locks of hair flowed out. His hair had a glowing sheen and extended his body length, until he cut it off and gave it to the Tree Witch. His hair subsequently began to regrow, as shown in "Mortal Folly," "Heat Signature," "Apple Thief," "Beautopia," "No One Can Hear You," "Another Way," "Beyond this Earthly Realm," "Gotcha," "You Made Me!," "Who Would Win" "The Hard Easy" "The Lich" "Jake the Dog" and "All the Little People." In "Another Way," Finn's hair nearly touched his shoulders, and later in "Beyond this Earthly Realm," Finn's hair was shown to have grown past his shoulders. In "Gotcha!," Lumpy Space Princess saw an illusion of Finn with hair reaching his waist. Finn's hair is also seen in "You Made Me!" when he blocks the blast from Lemongrab which caused his hat to rip off. A few strands of his hair also came out in "Who Would Win" after Finn got repeatedly beaten by Jake and they were evident throughout the majority of the episode. It makes an appearance in "The Hard Easy," having roughly the same length as in "Beyond this Earthly Realm." In "The Lich," Finn pulled off his hat showing it seemed a bit longer than in its last appearance in "The Hard Easy." 1 of 14Add photo===Clothing===

 * Main article: Finn's hat

Finn wears a white hat with two "ears" sticking out on top. The hat is inspired by a character called Bueno, a bear that appears in comics made by Pendleton Ward, the creator of Adventure Time. Consequently, Finn's hat is bear themed; coincidentally the Hyoomans wear animal themed hats as well. This might be a hint that humans in the Land of Ooo wear animal hats to fit in the society. Finn's hat covers his entire head except for his face. He also wears a light-blue T-shirt, denim shorts, a green circular backpack, rolled-down white socks, and a pair of black shoes. In "Ocean of Fear," his footwear appears to be black booties with white cuffs. In "It Came from the Nightosphere," Finn had a small pocket sewn onto his shirt that he carried Jake in. When he's in the Ice Kingdom, he occasionally wears a yellow sweater, but has also recently worn his pink sweater made by Princess Bubblegum. In "In Your Footsteps," the Bear wears Finn's clothes, which may mean that Finn has multiple sets of the same outfit, along with multiple hats.

He wears white briefs that made an appearance in "City of Thieves" when Penny stole his trousers at the end of the episode. In "Who Would Win," he was shown to wear a different pair with red elastic.

Finn sleeps in red footie pajamas that have appeared in many episodes, but in the animated short, he sleeps in a red sleeping bag in his regular clothes. In the series, the sleeping bag is beige.

Weapons

 * Main article: Finn's swords

Although Finn has wielded a number of weapons, he originally favored a gold sword. As of the episode "Mystery Train," Finn is shown using a new sword with a pink/silver blade and a red, twisted "root" handle. (Finn's original sword was destroyed by a black hole in "The Real You.") Along with his new root sword, his green backpack has a new side strap that can hold the sword while Finn is walking. In the episode "Dad's Dungeon," Finn and Jake ventured into Joshua's Dungeon, which was built by Joshua to toughen Finn up. In the dungeon, Finn retrieves Jake's family sword, which has replaced the root sword as his primary weapon.
 * Main article: Finn's crossbows

In "Conquest of Cuteness," Finn was shown to have a crossbow. He used a different one in "The New Frontier."

Personality and character traits
Though at times violent and aggressive, Finn is a brave and righteous hero. He has a very strong sense of responsibility and gets upset when he is unable to help others. He is almost physically incapable of doing anything evil or unjust, and will struggle greatly against doing such things, as seen in several episodes such as "City of Thieves," "Mortal Recoil," "The Eyes," and "The Enchiridion!" Even though he acts like a normal boy, Finn acts like a gentleman when it comes to ladies.

Finn is shown to be a fearless thrill-seeker and enjoys putting himself in the midst of danger simply because he enjoys a challenge. However, as illustrated in "Ocean of Fear," Finn has an unexplained phobia of the ocean, or thalassophobia, despite the fact that he can effortlessly come into contact with any other body of water. While he portrays himself as a rough and tough hero, Finn has a tender side capable of love and compassion, as shown by his boyhood crush on Princess Bubblegum and his brotherly relationship with Jake. However, Finn seems to hate romance movies and kissing because in "Go With Me," he actually vomits during a kissing scene in a movie. However, at the end of "Dream of Love," Finn was not grossed out by Tree Trunks and the Pig kissing. Finn's growth in accepting romance and physical love is also demonstrated when he willingly kisses Princess Bubblegum in "Too Young" and his current girlfriend, Flame Princess, in "Burning Low."

Finn’s aspirations to be a great hero makes him somewhat of a moral sheriff in the Land of Ooo, as he is willing to help and protect any innocent person or creature. Finn appears to be somewhat simple-minded, seeing that he gets a lot of conflicting emotions when it's unclear whether something is good or evil (exemplified by his dealings with Marceline in the episode "Henchman").

Many aspects of Finn's personality are shrouded in mystery. In the episode "Rainy Day Daydream," it was shown that Finn believes "imagination is for turbonerds who can't handle how kick butt reality is," showing Finn not only accuses imagination users as "turbonerds" and believes life is fantastic. Finn then refused to use his imagination until he had to reactivate Jake's "bombastic personality" in his imagination land, (which was just a basic gray and white empty plane hinting that Finn isn't very imaginative, but that was contradicted in "Power Animal" when the gnomes harnessed the energy from Finn's imagination) which was inhabited with a few dainty creatures such as Bellamy Bug. Finn's imagination was than powerful enough to effect the real world (like Jake's but to a lower degree) and turn on Jake's imagination.

Finn can also be very stubborn, such as in "Memories of Boom Boom Mountain," "Rainy Day Daydream," and especially in "Another Way." Finn can also be easily tricked, as in "The Eyes" when Jake convinced him that the giant hawks would take the horse to a land of sunshine and love stuff and take care of him. He can get overly angry and yell as in "Trouble in Lumpy Space" and "Tree Trunks (episode)," but he immediately feels guilt and remorse and apologizes when he can. Finn prefers to do work and not take the easy way out ("Business Time") and ("The Real You").

While Finn is shown to be a courageous warrior, he is also shown to have several fears. In "Another Way" and "King Worm, he is shown to have a fear of clowns. Also in "King Worm" he is shown to have a fear of Bubblegum calling him too young, and he also fears the return of the Lich, or possibly just the Lich himself. He is also shown to fear the Ghost Lady ("King Worm," and "The Creeps") and the ocean ("King Worm," and "Ocean of Fear").

Physical
Finn's first swordAdded by KoolioPhoebeFinn is proficient in several forms of combat, including hand-to-hand combat, magic, and swordsmanship. He can jump very high and is exceptionally strong and agile for a boy of his age. Despite his age and appearance, Finn seems to be quite strong and athletic; he can be seen wrestling full-grown Marauders, the large grass ogre Donny, and a general variety of monsters and creatures several times his size. Finn is also capable of lifting up Princess Bubblegum, as shown in "Mortal Recoil" when he picks her up and puts her in her bed, and capable of lifting up Marceline as seen in "Daddy's Little Monster." In addition, he was able to lift a tree and hit the giant spider Barb with it in "Web Weirdos." In "Another Way," Finn was able to run around carrying a giant cyclops' eye. Lastly, in "Dad's Dungeon," when he stabbed the Evil Monster in the eye, he was able to lift him up slightly off the ground and flip him into the pit. Being the size it is, the giant Evil Monster should have weighed at least a couple of tons, thus showing how strong Finn is. He also can make his arms and legs bend in inhuman ways, as during the Science Dance and when he uses "spaghetti limbs" (waving his arms and legs, which Jake can also do). In "The New Frontier," it's shown that Finn can make fire only with his hands. Finn is very tolerant to pain as shown in "No One Can Hear You" when the stag broke his legs; he just says, "Whatever." Also, in "The Lich", he was able to break the Enchiridion on his knee. Finn seems to have impecable balance, as he was able to balance himself on two wheels in his wheelchair in the episode "No One Can Hear You" however he refers to it as "skills."

Mental
Finn has the ability to mentally fight psychic abilities. The first time was against the Lich. The second time was against Goliad, as he was constantly able to manipulate his thoughts in order to avoid revealing the plan to defeat Goliad, allowing Princess Bubblegum to create Stormo. Finn can focus for a very long time as shown in "Still" when he spends hours telepathically summoning an Astral Beast. As demonstrated in "The Creeps," Finn can lock unwanted memories in "the vault," which is later seen in "King Worm." However, this is a normal human ability which is activated if the scene the person had witnessed is too traumatizing for them. Finn has the ability to read and write, and he can also do simple math.

Creative
Besides combat, Finn has displayed many other impressive abilities in handicraft. He has some origami skills, as shown in "Ricardio the Heart Guy," in which he makes Princess Bubblegum a paper crane, as well as in "Marceline's Closet," in which he makes a paper airplane. In addition to that, Finn is shown to be able to construct a sculpture (of the Candy Kingdom) from his saliva, which was also made for Princess Bubblegum in "The Real You." Finn is also somewhat gifted at constructing simple machines, such as the catapult in "The Witch's Garden." Finn writes and draws with his left hand and occasionally with both hands at the same time. He additionally handles his sword with his right hand, suggesting he may be ambidextrous, able to use both hands with equal skill.

Musical
Finn enjoys singing; after swallowing a tiny computer, he gained the ability to auto-tune his voice on command, although he can sing without auto-tune as well. Apparently, Finn can also play the flute, demonstrated in "Prisoners of Love," in which he played a short lick before javelin-throwing it at Ice King. Unfortunately, the flute fell apart before it could hit him, so Finn is not seen playing the flute again except as Farmworld Finn at the end of "The Lich." He is also very good at beat boxing as seen in "It Came from the Nightosphere" and "What Was Missing." In "Gut Grinder," Finn tries to play Jake's viola, but Jake says he stinks. Jake even imitates his foot prints and said "I'm Finn the Human and I stink at viola." However, during "Death in Bloom," Finn panicked over what instrument to pick, supposedly because he could not play any of them, and settles for sleigh bells. In the episode "Go With Me," Finn is seen playing the lute. In "Daddy's Little Monster," he is seen playing the tambourine.

Miscellaneous
Finn is very good at playing a video game called Adventure Masters, which he and Jake play on BMO from time to time. He can also spit very long distances, as demonstrated in "Evicted!," when he spits on Marceline, in "My Two Favorite People," when he spits on Tiffany's face, and in "Web Weirdos," when he spits at birds flying overhead, while suspended upside down on a giant spider web. In "Dungeon," one of the trials that Jake says Finn would have breezed through is a spitting competition against a goblin-like creature. In "Burning Low," Finn is shown to be able to spit water incredibly high into the air.

Temporary
Finn and Jake gained magical abilities in the episode "Wizard," but they have never used those abilities in any other episode. Pendleton Ward later revealed on his Formspring that all of the magic Finn and Jake gained in that episode was contained in their robes, which were destroyed.[9]

Likewise, in "The Chamber of Frozen Blades," Finn and Jake gain ice-ninja skills, but it's unlikely they will use them again because, according to Adam Muto, "They didn't have enough time to commit the incantations and hand positions to memory."[10]

Age
Finn was 12 years old at the start of the series and is progressively getting older.[11] As of "Mystery Train," he turned 13 years old. Finn is shown going through puberty throughout the series. This is seen whenever when he's screaming - his voice cracks. Finn's voice is noticeably deeper at 13 than it was at age 12, as a result of his voice actor aging. Episodes with early production codes have Finn with a very childlike voice such as "The Enchiridion," "Prisoners of Love," "Evicted," and "Ricardio the Heart Guy."

In an interview in early 2012 (at the end of season three), Pen Ward stated that Finn is now 14.[1]

Relationships
Being a hero, Finn has become quite popular in the Land of Ooo, starting many friendly relationships. ===Jake===

Fist PoundAdded by Moocowisi

Finn high-fiving JakeAdded by Dreb607As housemates, brothers and best friends, Finn and Jake share a very deep and strong bond. Having been raised together by Jake's parents, the duo share a relationship similar to that of siblings, with Jake acting as Finn's older brother. Though they have an unconditional love for each other, Finn can get frustrated with Jake because of his laziness and lack of motivation, shown especially in "The Witch's Garden." As a more laid-back character, Jake often tries to relax Finn's fiery personality in the face of a struggle, advising him not to worry in most situations. Though he sometimes leads Finn down the wrong path, Jake genuinely means well for his companion and is usually an encouraging and protecting figure in Finn's life. Finn and Jake have saved each other's lives on several different occasions, and often adventure throughout the Land of Ooo together. A unique part of Finn's relationship with Jake, is that Jake is able to tell when Finn is about to cry, as shown in the episode "Freak City" and is stating to be a "mother daughter thing".

Lady Rainicorn
Lady Rainicorn, Jake, and FinnAdded by PotatogurlFinn became friends with Lady Rainicorn after Jake wanted to hang out with both of them at once in the episode "My Two Favorite People." At first Jake regretted introducing the two, but in the end he was glad it happened. Finn and Lady Rainicorn still share a close bond, despite the fact that Finn can't understand Lady Rainicorn's fluent Korean. ===Princess Bubblegum===

Bubblegum kissing FinnAdded by Maciek pi

Finn and Princess Bubblegum kissing.Added by BladeGuy9Finn had a rather obvious crush, which he denied before the events of the episode "Wizard Battle," on Princess Bubblegum, whom he occasionally calls "Peebles" and other nicknames out of affection. He is known to interact with her more than any of the numerous other princesses of Ooo, and would jump at the chance to do anything for her. Finn becomes very protective and jealous when someone else comes between them, as seen in "Ricardio the Heart Guy," in which he sought to one-up Ricardio (obnoxiously performing the Science Dance, as a desperate ploy to attract Princess Bubblegum's attention) and expose him as a villain. Though the princess is seemingly oblivious to Finn's affection, she often calls on him for any royal need. In "The Real You," Princess Bubblegum kisses Finn on the cheek, and he faints a moment after the kiss.

Finn eagerly hoped to win the princess over with his heroic deeds. Finn and Princess Bubblegum share a staunch sense of morality and often work together to bring justice and balance to the Land of Ooo. Taking several dangerous and tomboyish cues from Marceline in "Go With Me," Finn tries to set up a movie date with Princess Bubblegum, who banishes Finn from the Candy Kingdom until he stops "acting like a psycho."

In "Mortal Folly," when Finn and Jake are chasing the Lich King, the Ice King persistently nags them to give him their blessing to marry Princess Bubblegum. When the Ice King says, "It's not like you want to marry her," Finn blushes and angrily throws a rock at him. Earlier in the episode, before embarking on their pursuit of the Lich, Princess Bubblegum gives Finn a pink, heart sweater that she knitted for him. This sweater would later protect Finn against the Lich using the "power of liking someone a lot," as Finn put it. (He later refers to the sweater as his "like-like sweater.")

In "Mortal Recoil," Finn outwardly confesses to the princess that he "likes her a lot," although it is unknown whether she actually heard him, as she was still possessed by the Lich at the time. Princess Bubblegum, whose incomplete reconstruction at the end of season two (resulting from the candy surgeons' inability to completely recover all the pieces of her bubblegum body) caused her to revert to her 13-year-old self, hugs Finn after her recovery and calls him "hero." They later share a kiss in "Too Young." However, his grip on the princess' heart loosens after her re-aging and she can only remember the hug (though she was joking, as confirmed by Natasha Allegri). Finn feels beaten afterwards, but a pep-talk from Jake brought his spirits back up. In "Wizard Battle," Finn got a kiss from Princess Bubblegum again after winning the Wizard Battle where she kisses him and then slaps him for cheating.

As of "What Was Missing," it is revealed that Finn has kept Princess Bubblegum's wad of hair from "To Cut a Woman's Hair" and spends quite a bit of alone time with it, as stated by Jake.

After being rejected several times, in "Incendium," Finn becomes deeply depressed and cries over Bubblegum by a little shrine he constructed made up of two framed pictures of her, his lock of her hair, and a pool of his tears. He becomes enraged and states that he'll kill whoever started a fire that burned his two pictures of Bubblegum. After his brief encounter with the Flame Princess (who started the fire) and saying that he likes her, and later saying that he thinks he has a crush, it is unknown if Finn has completely moved on from Princess Bubblegum or if he had just been distracted by the commotion and a new princess his own age, exhausted his tear supply, and/or only somewhat moved on due to his new crush.

In "In Your Footsteps," Jake says that Princess Bubblegum was his ex-girlfriend, but Finn replies they "never went steady."

In "Burning Low," he thinks the Princess Bubblegum is jealous after hearing from Jake. When he goes to write poetry for Flame Princess, Bubblegum finds him, saying, "I'm glad you understand why you can't be with Flame Princess." This makes him angry, and he reveals to her that he was formerly in love with her, but because she didn't love him back he is ready to move on. Bubblegum also knows that if Finn and Flame Princess kiss she would destroy the world from the inside out.

In "The Lich," Finn shows animosity toward the Princess when she accidentally cuts him with her scissors while he is stealing the jewel from her crown. This is possibly due to his being influenced by the Lich impersonating Billy.

In All the Little People, Finn puts himself and Flame Princess together before putting himself and PB together.

Marceline
Finn and Jake's first meeting with Marceline.Added by YazzyDream

Marceline kisses Finn for the first time.Added by Bankaibuddy15Though he initially considers her an enemy in her debut, "Evicted!," Finn quickly befriends Marceline the Vampire Queen, as he learns that her seemingly evil ways are just playful teasing. A rowdy and adventurous character, Marceline and Finn share the same vigor and thirst for danger. One of the key reasons why they managed to forge a friendship is that Finn saved her life in "Henchman" when Jake exposed her to direct sunlight and threw garlic at her in a misguided attempt to save his friend Finn. In the same episode, Finn, in an attempt to convince Jake of her generally wholesome ways, calls Marceline "a radical dame who likes playing games." As previously stated, Marceline loves to mess with Finn's head. Despite Jake's fear of Marceline (and of all vampires), Finn enjoys spending time with her so that they can be "awesome together." In "Go With Me," Finn asks her to go to "Couples-Only Movie Night," but only as a friend. Being (mutually) disgusted to the point of vomiting by the idea of kissing (although ironically she has kissed him on the cheek at least twice), Marceline has no interest in dating Finn. In "Marceline's Closet," he accidentally sees her naked when Jake tells him to see if the coast is clear for them to get out of her house, causing him much discomfort. ===Ice King===

Finn, Jake, and the Ice King enjoying some quality time.Added by LittleGhostPrankster

Finn kicking the Ice King.Added by Alucards FlameAs the story's recurring antagonist, Ice King and Finn are frequently at odds. Finn is prone to impatience and quick aggression around him but can show him sympathy, as in "When Wedding Bells Thaw." However, Finn's aggression never outweighs his compassion, honor, and respect for life, as evidenced when he refused the opportunity to slay Ice King as Billy had slain the Fire Count. Similarly in "Mortal Recoil," Finn, albeit grudgingly, trusted and united with Ice King against their common enemy of the Lich-possessed Princess Bubblegum. Further contributing to their differences, Ice King competes with Finn for Princess Bubblegum, until the closing scene of season two. This mutual attraction for Princess Bubblegum can be clearly seen in "Mortal Folly," where Ice King continually pesters Finn for consent to wed Princess Bubblegum. Upon Ice King's saying, "It's not like you wanna marry her," Finn blushes and hurls a rock at Ice King.

Although Finn and the Ice King started out as bitter rivals, their relationship progressed to a friendly rivalry, then an odd friendship in its own right, and finally a genuine friendship.

The Ice King does not reallyhate Finn and Jake, as he only fights with them because they are opposing each other in terms of morals. He frequently tries to be friends with them (in his own, misguided way) and has willingly made alliances with them. In the episode "Still" The Ice king freezes Finn and Jake so they can have "bonding time." It was shown in "Hitman" that while Finn and the Ice King are rivals, they are not enemies, and don't harbor any real malice towards each other. The Ice King made it clear that he doesn't want to kill Finn, the most he would do is punch him in the belly and make him vomit up his lunch. At worst, they are battling rivals, as Finn openly disapproves of the Ice King's habit of stealing princesses and causing mischief. At best, they are playful rivals, even friends. In "Holly Jolly Secrets Part II," the Ice King has a locket with the pictures of Finn and Jake. Near the end of the episode, the two are shown snuggled up side-by-side by a roaring fire, wearing ugly Christmas sweaters. Finn's attitude towards the Ice King has softened since discovering the tragic secret of his origin, and his compassion for people in distress outweighed his petty squalls with him enough to be his friend. ===BMO===

BMO entertaining Finn and Jake.Added by Treetrunks98BMO lives with Finn and Jake in the Tree Fort. He serves as their living video game system, film editor, camera, and many more portable electric items. He appeared in the eighth episode of Adventure Time, so it is obvious he has been with them for a long time. In "Video Makers," BMO records the footage requested by Finn and Jake, although they disagree on what genre of movie it will be, so they leave him a note that tells him to keep only the best footage and present it at the Movie Club. He ends up bringing them together by using both the action and comedy/romance footage and singing his BFF Song, so it appears he doesn't take sides with either of them. In "Incendium," BMO's video game music inspires Finn to sing All Gummed Up Inside, then BMO helps watch him while Jake courts Flame Princess, and pulls a kancho prank on him. ===Flame Princess===

Flame PrincessAdded by Blugo34Finn first meets Flame Princess at the end of the episode "Incendium." During the episode, Jake had been posing as Finn trying to court her because he believed that Finn, depressed after being rejected again by Princess Bubblegum, needed a new love interest. However, when Flame Princess's father tells Jake that she is evil, Jake tells her (disguised as Finn) that he doesn't like her, which causes her to become confused and angry and attack him, following him back to the tree fort where the real Finn is. She starts a fire in the house which burns the pictures in Finn's shrine to Princess Bubblegum, and he becomes enraged and runs to see who ruined his shrine. He is surprised to see it's Flame Princess. When she accidentally lights the liquid pyrotechnics left behind by Princess Bubblegum and douses her fire, he saves her and brings her into the house. When she regains consciousness, Flame Princess yells at him, "You! What's wrong with me huh?! You don´t like me?!" and Finn states, "I like you!" Flame Princess blushes. She then slaps Finn and warns him never to mess with her again, and flees the tree house. After she slaps him, he immediately wanted to know who she was. He then told Jake, "Dude, I think I have a crush." showing that he may be in love with her.

In the continuation episode, "Hot to the Touch," she officially becomes Finn's new love interest. He asks Jake to Finn and Flame Princess.Added by Breathe Tomorrow

help him find her, saying that he "peeped beyond her burning gaze" and that "she ain't evil," and the two run out to look for her. They spied her by a pond and hid behind the bushes to watch her. Finn affectionately likened her to "the steam off a puppy's nose searching for ham in snow" and "a cute little flower." When she curiously dips her hand in the pool and jumps back in pain, Finn rushes to her aid, surprising her. Finn admits to Flame Princess that he really likes her and they should be together, which causes her to glow brighter and makes small fires appear around her. Finn was surprised with the fire getting near him, so he tried to put them out, not knowing that by putting out the flames he was hurting Flame Princess. Angry and confused, she ran again and the brothers chased after her, then she ambushed them. However, the attack does not last long, and Finn confuses Flame Princess by trying to compliment her while she is trying to kill them. He then tries to explain his feelings again which causes her to blush, but she resists. Upset that when Finn makes her glow brighter, he puts it, she warns him that he "should not toy the emotions of a fire elemental." Flame Princess says that fire's purpose is to burn and proclaimed that this land (Goblin Kingdom) will be her own Fire Kingdom. Finn tried to convince her not to do it.

She refused and cast a wall of fire to back down Finn and Jake. When they flew to Goblin Kingdom with fire-proof suits, Flame Princess attacked them with fireballs but they had no effect. She again shoots another fireball at Finn, but this was deflected and instead hit a cart. Jake extinguished the cart's flames, consequently hurting Flame Princess once more. Finn distresses that he doesn't want to hurt Flame Princess, but his morals say he must help the citizens of the Goblin Kingdom. Neptr, thinking he's helping, engages the foam blaster to extinguish her. However, Finn manages to stop Neptr from directly hitting Flame Princess and instead he hits Jake and a few of Flame Princess' flames, hurting again Flame Princess. Flame Princess then gets extremely angry and proclaims, "That is the last time you hurt me," and grows into her beast form, a towering human-shaped fire. A fiery tear from Flame Princess' right eye is revealed that she was harmed both physically and emotionally. Finn shouts, "No more! No more!" and literally rips himself out of his own suit and stands on top of it, shouting out to Flame Princess. However, he is ignored.

Finn, angry and upset that he can't "just like a girl," begins to cry. A tear of his falls on the flames of Flame Princess, stinging her and catching her attention. Flame Princess watches Finn cry, confused and amazed, then stops her flames and approaches him. She says that now she believes that Finn is a Water Elemental because he "creates water," or cries. Flame Princess says that no matter how much they like each other, they can't be together because they are of conflicting elements. Finn tries to explain that he isn't, but Flame Princess has trouble understanding the concept and says even if they liked each other, they would only hurt each other. Finn replies, "No, I can take it. I mean...we can try." Flame Princess glows, touched that he "would defy nature for" her. She hugs him, and although he smiles for the first few seconds, Finn begins to burn up and pushes her away. Flame Princess then bids him goodbye.

Finn and Flame Princess' first kissAdded by Monsterlexi

Finn saves Flame Princess with a kissAdded by MonsterlexiIn "Burning Low," she and Finn are dating. She even thanks him for building her house and they hug each other. He decides to go to "tier two (smooching)" after another date, but only receives five hugs, which according to Jake, does not count as "tier two." Embarrassed, Jake then gives Finn the idea to write her a "sappy poem." Finn also gets angry at Princess Bubblegum for wanting him to stop seeing her. Then, when Jake is convinced what would happen if Finn kisses Flame Princess, he and Princess Bubblegum try to stop it, but arrive to see them already kissing. When Flame Princess falls into the earth's crust due to her instability, Finn goes in to save her, with Jake cutting off her oxygen supply. After using artificial respiration to revive her, they continue to date.

In "Ignition Point," Finn and Jake go to the Fire Kingdom to retrieve Flame Princess' scented candles.
