Finn

Finn (full title: Finn the Human and formerly known as Pen in the original short) is the main protagonist of the series Adventure Time.

Background


As shown in "Memories of Boom Boom Mountain," Finn appears to have been abandoned in a woodland during infancy. He reveals that he made "boom boom" (a reference to poo) 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 his Baby Finn 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 may be the last human in the Land of Ooo, or possibly the world. 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 Hyoomens 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, so 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 or the Old Man Henchman) have been confirmed by the show's creator, Pendleton Ward, to be mutants or humanoids.

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


Finn is a 14-year-old human. He has very thin, noodly limbs. He has several missing teeth because he bites trees and rocks among other things.

Although his eyes typically lack detail and appear as small black dots due to a minor mutation, 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. (But as stated by Andy on Formspring,"That was a special occasion. The heterochromatic effect was a byproduct of him being hypnotized by that guardian dude." Andy Ristaino confirmed that Finn's eyes are blue.

Hair
thumb|right|300px|Finn's Magical Hair Finn has blonde hair which can be 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," and "Another Way." In "Another Way," Finn's hair was shown to have grown past his chin.

Clothing
Finn wears a white hat with two "ears" sticking out on top. He has proclaimed it to be "awesome." Finn's hat is bear themed; coincidentally the Hyoomens 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 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 (see:Finns_Booties). 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," 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.

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
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. There, Finn retrieved Jake's Family Sword, which has replaced the Root Sword as his primary weapon.

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," "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, which may be explained in a future episode, 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. But at the end of Dream of love, Finn was not grossed out by Tree trunks and the pig kissing.

His aspirations to be a great hero make Finn 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 kickbutt 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 who represented Finn's secret desire to be civilized (that he will not admit to). 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 occasionally be a little self-centered such as in "Freak City," and "The Creeps" when he named himself "Prince Hotbod." 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 near immediately feels guilt and remorse and apologizes when he can. Finn prefers to do work and not take the easy way out ("Business Time").

Physical
Finn 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. 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 with his hands.

Finn is also capable of lifting up marceline as seen in Daddy's little monster.

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, Finn has not played the flute in any episode since, this is may be because of it breaking. He is also very good at beat boxing. 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.

Miscellaneous
Finn is very good at playing a video game called Adventure Masters, which he and Jake play on Beemo 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. As demonstrated in "The Creeps" Finn can lock unwanted memories "in the vault". This, however, 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.

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.

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."

Age
Finn was 12 years old at the start of the series and is progressively getting older. 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 slightly deeper at 13 than it was at age 12, as a result of his voice actor aging.

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

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

Jake
As both 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 have 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 others lives on several different occasions, and often adventure throughout the Land of Ooo together.



Lady Rainicorn
Finn 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
Finn had a rather obvious crush, which he denied before the events of the episode "Wizard Battle," on Princess Bubblegum, who he occasionally calls "Peebles" 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 PB, 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 PB. When the Ice King says "it's not like you want to marry her," Finn blushes and angrily throws a rock at him, implying that he did wanted to marry PB. Earlier in the episode, before embarking on their pursuit of the Lich King, 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 2 (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 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. 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, 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 lit that fire when his two pictures of Bubblegum are burned. After his brief encounter with the Flame Princess 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 on account of his new crush.

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



Marceline
Though 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 in 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, Marceline has no interest in dating Finn. In "Marceline's Closet," he accidentally saw her naked when Jake told him to see if the coast was clear for them to get out of her house, causing him much discomfort.



Ice King
As 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 2. This mutual attraction for PB can be clearly seen in "Mortal Folly", where Ice King continually pesters Finn for consent to wed PB. 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 really hate 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 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 helps keep watch of Finn while Jake talks to the Flame Princess, and also pulls a Kancho prank on him.



Flame Princess
In the episode "Incendium", Flame Princess yells at him, "You! What's wrong with me huh?! You don´t like me?!", then Finn states "I like you!". She blushes. Flame Princess then slaps Finn and warns him never to mess with her again, then fled. 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 becomes Finn's new love interest. Finn "peeped beyond her burning gaze" that she ain't evil, she's passionate and went after her with Jake. They spied her behind the bushes, Finn viewed her like a steam of a puppy's nose searching for ham in snow and a cute little flower. Finn admitted to Flame Princess that he really likes her and they should be together. Finn was surprised with the fire getting near him, he then tried to put it out and physically harmed her. Flame Princess ran and Finn chased after her, then she ambushed them. Upset that when she glow brighter, Finn put it out that he should not toy the emotions of a fire elemental. Flame Princess proclaimed that this land (Goblin Kingdom) will be her own Fire Kingdom and Finn tried to convince her not to do it.

However, she refused and cast a wall of fire to back down Finn and Jake. When they returned to Goblin Kingdom with fire-proof suits, Flame Princess attacked her with fireballs but were nullified by the suits. She again shoots another fireball at Finn, but was deflected (again, by the fire-proof suits) and instead hit a cart (which a goblin said that he was born in). Jake extinguished the cart's flames, consequently hurting Flame Princess once more. NEPTR engages the foam blaster to extinguish her. But Finn manages to stop NEPTR from directly hitting Flame Princess and instead he hits Jake and a few of FP's 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 and continues to rampage through the Goblin Kingdom. A tear from FP's right eye is revealed that she was harmed both physically and emotionally. Finn shouts "no more, no more!" and then literally rips himself out of his own suit (never again wanting to hurt her, or see her hurt), stands on top of it and shouts out to Flame Princess but is ignored.

Finn begins to cry and a tear of his falls on the flames of Flame Princess and not only hurt her, but catch her attention. Flame Princess watches Finn cry for a little then stops all her flames from destroying the city and says she thinks she understands now and that Finn is a water elemental because he creates water (tears). She showed that she liked him back but thought they couldn't be together because she thinks of him as a water elemental. 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 says "No, I can take it, I mean...we can try", and hugs her but Finn gets burned and begins to tear up again so Flame Princess says goodbye and leaves. Afterwards, Jake asks how things went with Flame Princess. Finn tells Jake "She hugged me, then left." Jake replies "Whoa, how did it feel?" Finn responds "it hurt," smiling.

Magic Fist
Magic Fist is the alter-ego of Finn and Jake that first appeared in "Wizard Battle." He's not a real wizard; he only entered Wizard Battle to save Princess Bubblegum from having to kiss Ice King for the prize was a kiss from her on the lips. He wore a blue eye mask, an electric-green hood, and a large red robe. Finn was the head, while Jake was the body. See the gallery section for more images.

Prince HotbodModelsheet finn intuxedowithmask.jpg
In the episode "The Creeps" Finn wears a black tuxedo ending in a split tail with blue trimming on the collar, a matching blue bowtie, a gray vest, a brown and tan fox mask over his characteristic hat, and brown "fancy gloves".

Giant Foot FinnGiant foot finn.jpg
In the episode, "Freak City," Finn was turned into a foot by a magic man posing as a beggar, he then discovered that the magic man had turned many people into body parts.

Zombie Finn[[Image:Zombie Finn.png|100px|right]]
Zombie Finn looks like Finn, and apparently appeared in "Slumber Party Panic." Zombie Finn appears when the zombies break the barricades, in the bottom left corner of the first window to be broken open. Zombie Finn also appears in the Adventure Time game, Rhthym Heroes. In the game, Finn appears as a zombie just like in Slumber Party Panic. He seems to be controlled by Marceline in the game, and he is next to two other zombies, a cupcake and a candy heart.

Lumpy Finn
In the episode "Trouble in Lumpy Space" Finn turns into a Lumpy Space person to give the antidote to Jake so that he can return back to his normal body, but by doing this, he turns into a Lumpy Space person as well.

Lumpy Finn hates Lumpy Jake.



Demonic Finn
In Daddy's Little Monster, Finn puts on the Nightosphere Amulet to rescue Jake and Marceline from the Nightosphere. This causes him to transform into a huge, monstrous, demonic form similar to Hunson Abadeer. Afterwards, he tried to pull Jake and Marceline back in. He is reverted to his original form by Hunson himself.

Paper Plate Demon Finn
To sneak into the Nightosphere in the episode Daddy's Little Monster, Finn disguises himself by putting on red pajamas, cutting a paper plate and putting it on his face, and taping forks to his ears.

Hug Wolf Finn
In the episode Hug Wolf, Finn is hugged by The Alpha Hug Wolf on a full moon, causing him to transform every night into a Hug Wolf himself. When he is in this form, he must go on a hugging spree to fulfill his hug lust. When he awakens each morning after being in this form, he has no memory of the night. When a Hug Wolf, Finn's hands and feet are heart-shaped, he has shaggy grey fur, and he wears torn clothing. He is cured when he hugs the Alpha Hug Wolf, curing her as well.
