"I'll slay anything that's evil. That's my deal!" —Finn
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 true 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.
Ice king was once human since it showed him in Holly Jolly Secrets Part II, but was transformed into a blue humanoid by his crown.
Marceline could have also been a human, due to her memory as a little girl. In that memory, young Marceline appears to not have bite marks on her neck, indicating that she is not a vampire yet.
Appearance and Equipment
Main article: Finn's hat Finn is a 14-year-old  human. He has very thin, noodly limbs and wears a white hat with two "ears" sticking out on top, which he has proclaimed to be "awesome." Finn's hat is like a bear and ironically, in the episode "Susan Strong," Susan appears to be human and she wears a hat like Finn's but is more cat-like than Finn's hat. This might be a hint that humans in the Land of Ooo wear animal hats to fit in the society. His 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. When he's in the Ice Kingdom, he occasionally wears a yellow sweater, but has also recently worn his purple sweater made by Princess Bubblegum. He has several missing teeth because he bites trees and rocks among other things.He has also eaten a broom in the episode "Wizard." Ward has also stated that Finn has blonde hair which can be seen in "To Cut a Woman's Hair," where Finn removed his hat (one of three times he has done so), 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" , "No One Can Hear You ", and "Another Way ". He wears white briefs that made an appearance in "City of Thieves," when Penny stole his trousers at the end of the episode.
Although his eyes typically lack detail and appear as small black dots, 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.
Main article: Finn's swords
Although Finn has wielded all 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.
Main article: Finn's crossbows
In "Conquest of Cuteness," Finn was shown to have a crossbow. He used another one in "The New Frontier," but it was a different one.The one he used in "The New Frontier " seems to be the one Crossbow Guy had in the episode "City of Thieves."
==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.
His aspirations to be a great hero makes Finn somewhat of a moral sheriff to the Land of Ooo, as he is willing to help and protect any innocent creature in his strange world. 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.")
He has however, displayed a disturbing display of forceful repression when confronted with an event that is frightening and unexplainable, and it's been hinted at that this happens far too often to be entirely healthy. ("The Creeps", "This one's going in the vault.") This, however, can be demonstrated by any individual. It is normally referred to as repressing memories. If something occurs as extremely traumatic in one's life, as they grow older, the experience may be repressed and thought of as a dream or not thought of at all. (See 'Repressing Memories ')
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).
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. 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.
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 unraveled before it could hit him, and Finn has not played the flute in any episode since. He is also very good at beat boxing. In "Gut Grinder," Finn tries to playJake's viola, but Jake says he stinks.
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 and in "My Two Favorite People," when Finn spits on Tiffany's face. 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" and by doing so a lump appears on his forehead while he represses. This, however, is a normal human ability, which is activated if the scene the person had witnessed is too traumatizing for them.
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."
Being a hero, Finn has become quite popular in the Land of Ooo, starting many friendly relationships.
As 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 has 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.
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.
Finn had a rather obvious crush, which he denied before the events of the episode Wizard Battle, on Princess Bubblegum, whom 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 will 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 always eagerly hopes 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 does want 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-ageing 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.
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 account of his new crush.
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 accidently 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.
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.
Oddly enough, Ice King does not seem to 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". In "Holly Jolly Secrets Part II " we see the Ice King has a locket with the pictures of Finn and Jake.
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!" Flame Princess. She blushes. Flame Princess then slaps Finn and warn him never to mess with her again, then fled. After she smacked him, he immediately wanted to know who she was. He then told Jake "Dude, I think I have a crush.". Her fiery vigor, same age, and mysterious apperance are alluring to Finn.
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, a electric-green hood, and a large red robe. Finn was the head, while Jake was the body. See the gallery section for more images.
