Finn the Human

Finn the Human is the main protagonist from the Adventure Time series.

Finn sets off on magical random quests around the Land of Ooo. He would gladly fight or beat up anything evil, but would not harm anything good or "neutral" as shown in "The Enchiridion!" when he refused to squash an innocent ant. Having a strong moral code, Finn swore that he would help anyone in need and often performs heroic feats to save the day; however, Finn's enthusiastic nature becomes more toned down as the series progresses, suggesting he is both maturing and developing as a character as he ages.

Appearance
Finn is a teenaged human. He was roughly five feet ten tall at the show's debut, but sometime between "The Cooler" and "The Pajama War," he underwent a growth spurt and is currently very nearly as tall as Princess Bubblegum. He is missing several teeth due to his habit of biting trees and rocks among other things.

Although his eyes typically lack detail and appear as small black dots, they are shown to have color in "The Enchiridion!" while Finn is undergoing Dark Magician's trials. 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, "That was a special occasion. The heterochromatic effect was a byproduct of him being hypnotized by that guardian dude." He went on to confirm that both of Finn's eyes are blue.

Finn's weight seems to fluctuate between episodes, with him seeming chubbier in some instances than others. Pendleton Ward stated on the "In Your Footsteps" commentary on the Season 4 DVD that his weight depends on how active he is adventuring, along with his diet, so it often changes.

In "Escape from the Citadel," Finn's right arm is actually torn off and then coated by the blood of a Citadel Guardian, which grows a small flower. He later got his arm back in the episode, "Breezy," where the flower stub matured into a tree and broke away like a cocoon, revealing a new limb, with a green thorn protruding from the palm. This thorn was later revealed in "The Comet" to be part of the Grass Sword sticking out from his skin, as his new arm was made of grass.

In "Reboot," Finn's Grass Sword detached from his arm and fused with the Finn Sword which combined into Fern. Because of this, Finn is an amputee again. However this time there is no flower growing out of where his arm should be and as of "Two Swords" Finn has a mechanical arm but in "Come Along With Me" his mechanical arm fell off when entering Golb's mouth.

Finn has blonde hair which is first seen in "To Cut a Woman's Hair," where Finn removes his hat, and long, golden locks of hair flows out. His hair has a glowing sheen and extended his body length until he cuts it off and gives it to the Tree Witch. His hair slowly begins to regrow throughout several episodes until "Another Way" where it has grown to his shoulders. By "The Lich," Finn has grown his hair slightly longer than in its appearance in previous episodes. However, in the episode "Davey," Finn shaved off almost all of his hair for the second time so he can disguise himself as 'Davey', but begins to regrow it in "Little Dude," and the episodes after it. In "Puhoy," an adult Finn is shown to have grown facial hair and his hair becomes curly although since that part of the episode was a daydream it may not be 100% accurate. In "May I Come In?" Finn's long hair is shown to have grown back to around the length it was in "To Cut a Woman's Hair," when Finn takes off his hat while acting as bait to lure out The Hierophant. Finn has once again shaved off most of his hair as revealed in "Temple of Mars" as a result of catching lice from Marceline. Finn's hair became mostly stubble after shaving it. Finn takes his hat off again in "Come Along With Me" unveiling that he has grown back some of his hair since the episode, "Temple of Mars."

Finn appears to not care for his hair much whatsoever, showed in how he frequently cuts it completely bald when asked (such as in "To Cut a Woman's Hair"), and in "Davey" when he shaves and slathers his hair in molasses, while BMO cries and claims Finn's "beauty is detroyed" and then says he looks like "the devil!"

Finn typically wears a munsell blue ("color #0093AF") T-shirt, denim shorts, a two-colored lime green circular backpack, rolled-down white socks, and a pair of black shoes. Finn's most prominent attire is a white hat with two "ears" (which Joshua calls "nubs") sticking out on top that covers his entire head minus his face. The hat is inspired by a character called Bueno, a bear from a Pendleton Ward comics. Finn can occasionally be seen in variations of his standard outfit. In "Ocean of Fear," his footwear appears to be black booties with white cuffs. In "It Came from the Nightosphere," Finn has a small pocket sewn onto his shirt that he carries Jake in. This appears again in "Davey" where he uses it to hide Jake while Finn steals the keys from the guards as he breaks the former out of jail. During "In Your Footsteps," the Bear wears Finn's clothes, which suggests that Finn has multiple sets of the same outfit, including his hat. However, in "Little Dude," when Finn's hat comes to life and is set free, Jake tells Finn, "Okay, let's go skin an evil bear," which may imply that Finn only had one hat.

Aside from his normal outfit, Finn can be seen wearing a cream-yellow sweater in colder areas such as the Ice Kingdom but would wear his pink sweater made by Princess Bubblegum occasionally. In "Holly Jolly Secrets Part II," he wears a dark blue sweater with Christmas decorations on it and a green scarf. Finn also wears white briefs that make their first appearance in "City of Thieves" when Penny steals his shorts 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 appear 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.

Personality
Although at times impulsive and aggressive, Finn is a kind, brave, selfless, and righteous boy. His aspirations to become 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 has a very strong sense of responsibility and becomes upset when he is unable to help others. Due to this and being somewhat simple-minded, Finn often feels conflicted when it is unclear whether something is good or evil as exemplified by his dealings with Marceline in the episode "Henchman."

Despite his heroic nature, Finn also takes a liking to a "normal life" without any recognition or praise for being a hero and demonstrates this in "Davey."

Finn is also almost incapable of doing anything evil or unjust, and will struggle greatly against doing such things, as seen in several episodes such as taking part in thievery in "City of Thieves" or killing a neutrally aligned and in "The Enchiridion!." However, Finn undergoes a slight change in "Wake Up" after he realizes that his father, whom he had high hopes of being a great hero, is nothing more than a selfish criminal. This, coupled with the loss of his favorite arm and sword due to his father's selfishness, pushes Finn to the point of wanting revenge. This is shown in "The Tower," where he attempts to go into space by building up a tower so that he could find his father, punch him, and take his arm. However, in the end, Finn learns to control his feelings of revenge with the help of Princess Bubblegum.

While he portrays himself as a rough and tough hero, Finn has a tender side that is capable of love and compassion, as shown by his boyhood crush on Princess Bubblegum and his brotherly relationship with Jake. Finn is also able to act like a gentleman when it comes to ladies. However, Finn seems to hate romantic scenes to the point of vomiting as seen in "Go With Me." However, Finn demonstrates growth in accepting romance and physical love as he willingly kisses Princess Bubblegum in "Too Young" and his latest ex-girlfriend, Flame Princess, in "Burning Low." His tolerance is seen again near the end of "Dream of Love," as he is no longer disgusted by Tree Trunks and Mr. Pigs' passionate kissing. Finn's care for his friends makes him very protective of them as demonstrated when Tree Trunks almost gets killed in the episode "Tree Trunks" and Jake in "The New Frontier." Overall, Finn is a very kind and selfless person who is always putting the safety of others above his own. Jake comments on his adopted brother by saying that "he is a good kid with a kind heart."

In the episode "Rainy Day Daydream," it is shown that Finn believes that "imagination is for turbonerds who can't handle how kick-butt reality is" and that he finds real life to be better than anything imaginary. Finn then refuses to use his imagination until he has to reactivate Jake's "bombastic personality" in his imagination land, (which was just a basic gray and white empty plane hinting that Finn is not very imaginative). However, this is disputable when the gnomes harness the energy from Finn's imagination in the episode "Power Animal" despite it being inhabited with a few dainty creatures such as Bellamy Bug. The gnomes state that Finn's imagination is powerful enough to affect 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," "Wizard," "Dungeon," "Rainy Day Daydream," and especially in "Another Way." This is likely a reason why Finn is often determined to work without taking the easy way out as seen in "Business Time" and "The Real You." Finn can also be easily tricked, as in "The Eyes" when Jake convinces 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," but immediately feels guilt and remorse and apologizes when he can. Finn is also quick to try and resolve problems that he may have caused, such as when he caused Flame Princess to get hurt by the Ice King. Finn is also empathetic and this was developed when he was an infant since no one (except Jake's parents Joshua and Margaret) helped him.

As a courageous warrior and a fearless thrill-seeker, Finn enjoys putting himself in the midst of danger simply because he enjoys a challenge as shown in "Jake Suit." However, he is also shown to have several fears. In "Another Way" and "King Worm," he demonstrates a fear of clowns. Also, in "King Worm," he shows a fear of Bubblegum calling him too young. In both "King Worm" and "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. Other fears that Finn has are the Ghost Lady, King Worm, and the Lich. Finn's fears change in "Billy's Bucket List," after he destroys Fear Feaster, a manifestation of his fears, with his grass sword while attempting to go into the ocean to fulfill Billy's wish. The Fear Feaster's death seems to have eliminated all of Finn's fears, or at least his fear of the ocean.

Despite being mischievous from time to time, Finn is a very kind-hearted person. It's shown multiple times that he shows clear concern for others, even for those who have willingly hurt him, such as in "The Enchiridion," he returned the dollar to the giant (note that this was the very same giant who ate his beloved brother Jake and even kept insisting that he was dead). Furthermore, he shows clear contempt for anything that is done out of immoral reasons.

Finn is also afraid of unknown vampires, as shown in "The Empress Eyes" when he hears Ice King breaking twigs. Thinking that it was a vampire, he starts throwing vampire hunting sticks into thin air.

Finn is also shown as willing to sacrifice himself in order to save others, as seen in the episode "James." With all other plans of escaping the Oozers showing no promise, Finn offered himself as a sacrifice without hesitation, so the others may escape. Though, He was knocked out and Princess Bubblegum convinced James to be the sacrifice instead.

Physical
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 is able to pick up a tree and hit Barb, a giant spider, in "Web Weirdos." In "Another Way," Finn is able to run long distances while carrying a giant cyclops' eye. Lastly, in "Dad's Dungeon," when Finn stabs the Evil Monster in the eye, he is able to lift it up slightly off the ground and flip it into the pit. Being the size it is, the giant Evil Monster should have weighed at least several tons, thus showing Finn's strength. Finn is also agile as he can jump very high and even 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 is shown that Finn can make fire only with his hands.

Finn is very tolerant to pain as in "No One Can Hear You" he merely says "whatever," when the Stag breaks his legs. Finn can also endure high temperatures, as seen in "Jake Suit" as he allows Jake to dip his head in lava, and also in "Rattleballs," when he sits in a mini-barbecue. This may be because he is already accustomed to heat from his relationship with Flame Princess. Also, in "The Lich," he is able to break the Enchiridion on his knee without any sign of pain, demonstrating considerable strength and resilience. He even tries to teach Jake how to tolerate pain in "Jake Suit," when he says, "just pretend like every bruise is a hickey from the universe." Finn seems to have impeccable balance, as he is 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." Finn is known to have deuteranopia, a form of heredity dichromatism that makes it difficult to distinguish green hues from red, as shown in "Red Starved." As this is a sex-linked genetic condition inherited on the X chromosome, Finn must have inherited the condition from his mother.

Magic wise Finn has obtained an immunity to electricity as well as electric based attacks thanks to magic spring water in Flute Spell this ability seems to have stuck with him as we see him display the non-effectiveness of electricity in Preboot against a giant electric eel and again in The Light Cloud against the Great Guardian.

Mental
Finn has the ability to mentally fight psychic abilities. The first time he shows this during the Lich's attempt to control his mind. The second time was against Goliad, as he was constantly able to manipulate his own thoughts in order to avoid revealing the plan to defeat her, 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 considered a normal human ability that occurs where certain memories are removed from the consciousness if it is too painful or traumatic for them to recall. Finn also has the ability to read and write, and he can also do simple math.

Fighting Style
Finn is proficient in several forms of combat, including hand-to-hand, magic, and swordsmanship. When using hand-to-hand combat, he is an aggressive fighter, combining some forms of martial arts or his amazing swordsmanship skills. Finn prefers overpowering his opponents, but he is also quick enough to understand an opponent's weakness or using his environment to win a fight. He also received training from the old gumball robot Rattleballs which dramatically improved his sword skills and his reflexes to greater levels.

Creativity
Besides combat, Finn displays 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 can also draw as seen in "The Thin Yellow Line" which he states that he isn't very good at it, as well as in "Mysterious Island" where he draws BMO and Susan. He is shown to be able to construct a sculpture of the Candy Kingdom from his saliva 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."

Musical
Finn enjoys singing; after swallowing a tiny computer, he gains the ability to Auto-tune his voice on command, although he can sing without it as well. Apparently, Finn can also play the flute, as seen in "Prisoners of Love," where he plays a short lick before javelin-throwing it at Ice King. Unfortunately, the flute falls apart before it could hit him. Because of this, Finn is not seen playing the flute until "The Lich" as Farmworld Finn and near the climax of "Finn the Human" when he shoves it into Tromo's nose. He is also very good at beatboxing 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 footprints 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 Master, which he and Jake play on BMO from time to time. Finn can also spit very long distances, as he demonstrates in "Evicted!," when he spits on Marceline, "My Two Favorite People," when he spits on Tiffany's face, and in "Web Weirdos," when he spits on 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. In "Who Would Win," Finn showers Jake with an abnormal amount of saliva through spitting. He also handles his sword with his right hand, suggesting he may be ambidextrous, able to use both hands with equal skill. This is also seen in "Frost & Fire," where Finn writes with his left and right hands and, occasionally, both at the same time. Finn is able to cook, although he leaves this task mostly to Jake. However, in "In Your Footsteps," it mentions and shows him making Finn Cakes.

Temporary
Finn and Jake gain magical abilities in the episode "Wizard," but they never use those abilities in any other episode. Pendleton Ward later revealed on his Spring that all of the magic that 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 is 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." Finn seems to speak Latin (as evident in "Morituri Te Salutamus,") although this may be caused by the magical powers of Fight King's arena. In "Daddy's Little Monster," for the first time, he becomes an antagonist by wearing the Nightosphere amulet, although it is only temporary. In "The Tower" Finn gains a new mental arm with the ability to interact with the physical world. His emotions seem to cause this, along with the ability of telekinesis. Since it was linked with his emotions, it exploded into a huge arm of spikes when he confronted his "dad," and disappeared when Finn's animosity abated.
