Finn Mertens (also called Finn the Human, Pen in the original short, and identified as P-G-8-7 Mertens[1]) is one of the main characters in Adventure Time.

Background

It is revealed in " Min and Marty " that Finn was born on Hub Island (one of the human-inhabited islands outside of The Land of Ooo) to his father Martin Mertens and his mother, Minerva Campbell . Having been a known con artist, Martin is confronted by an old foe and forced to flee the house with baby Finn while Minerva was at work. Martin brings Finn onto a raft, only to be attacked by the Guardian. Finn and Martin are separated as a result, with Finn being sent adrift towards Ooo and Martin disappearing.

As shown in "Memories of Boom Boom Mountain," the infant Finn eventually made it to Ooo, where he ended up alone in a forest. There, he went "boom boom" (Finn's word for defecation) on a large leaf and fell on it. He lay there crying until Jake's parents, Joshua and Margaret, rescued him from the wilderness and brought him to their home. They raised him alongside Jake , who, along with Jermaine, became Finn's adopted brother.

At end of the Distant Lands episode "BMO," Finn and Jake are shown at younger ages than their first appearances on Adventure Time, stick battling in front of the Tree Fort. By this point in time, Joshua and Margaret have most likely passed away, and Finn and Jake presumably no longer live with Jermaine.

It is revealed in "Susan Strong," that Finn knows nothing of his human parents or any other humans. In "Henchman," Finn states that Jake told him that he originated from a cabbage as a joke. However, Finn later learns about his biological father, Martin, in the episode "Billy's Bucket List" and his biological mother, Minerva, in the episode "Min and Marty."

Status as the last human

Main article: Humans

Finn was, for a long time, the only confirmed human in the Land of Ooo. The reason for this is revealed in the episode "Her Parents," as Lady Rainicorn's dad believed that humans were extinct.

Up until "Susan Strong," Finn believes he has never met another human and becomes morose and "soul-searchy" when he thinks about it. However, Finn encounters Susan Strong, a member of a tribe of mutants called Hyoomans. However, in "Beautopia," it is hinted that Susan Strong is unlike the rest of her tribe and may potentially be another human. In "Dark Purple," Susan removes her hat and reveals she is a human with a device on her head, making her possibly some sort of cyborg. However, it is unknown if Finn knew about this.

As of "Betty" Finn is no longer the last confirmed human because Betty Grof traveled through time from before the Mushroom War.

In "Billy's Bucket List," Finn is told by a deceased Billy that his father, Martin, is still alive and is trapped in the Crystal Citadel. This prompts Finn to travel to free his father in the episode "Escape from the Citadel," making him one of four known humans in existence at the time.

In "Preboot" it is revealed by the "human plus" Dr. Gross that are more humans outside of Ooo. This is further explained in the miniseries Islands, where it is revealed that roughly a thousand years prior to the main events of the series, a group of surviving humans from the Mushroom War fled Ooo on a container ship (as seen in Stakes) to escape from the vampires, oozers, and a comet. They eventually settled on a secluded island chain far from the mainland. Over the next thousand years, their community thrived and developed into an advanced technological society. While it was a veritable utopia, there were those few who occasionally grew dissatisfied with their rigidly structured lives and attempted to flee the island; these "hiders" were, in turn, hunted down and returned by specially trained "seekers." Finn, Jake, Susan Strong, and BMO went to the islands so that Finn could find out about his past and his species.

Finn for the first time saw large amounts of humans. Finn met his mother, Minerva while on the island. His mother is no longer a human and is now a virtual consciousness (A.I.) due to sacrificing her body in order to treat the human race from a virus. Finn was offered to live on the island but Finn decided to go home to Ooo rather than live with the rest of his species. So after the miniseries Islands, Finn being "the last human" was completely dispelled. Though in the Islands CN Side, Adam Muto stated that Finn being the last human in the world was never the most important thing about him.[2]

Although various other humanoids exist in the Land of Ooo, most have been confirmed by the show's creator, Pendleton Ward, to be mutants, such as Penny, Phil, or the Old Man Henchman.[3][4] According to Pendleton Ward's FAQ page, even Finn is mutated in some way.[5]

Appearance and equipment

Finn is a teenaged human. He was roughly five feet 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.[6]

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.[7]

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 torn off and 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. He then has a light gray mechanical arm as of "Two Swords". In the episode "Come Along With Me", his mechanical arm is bitten off when entering Golb's mouth.

Hair

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 flow 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 destroyed" and then says he looks like "the devil!"

Clothing

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.

Weapons

Finn has had a total of five major swords, not including his many temporary ones. He originally favored Scarlet, the Golden Sword, however after being turned into a 4-D Sword and then destroyed by a black hole in "The Real You", Finn is shown using the Root Sword (having a pink/silver blade and a red, twisted "root" handle) introduced in "Mystery Train". Finn's backpack also gains a new strap that can hold the sword. (3) In "Dad's Dungeon", Finn and Jake venture into Joshua's dungeon, built by Jake's father to toughen Finn up. Inside the dungeon, Finn retrieves the Demon Sword, which he used as his primary weapon until it was transformed into the Grape Sword and was destroyed in "Play Date". following these events, he purchases the Grass Sword, as seen in "Blade of Grass". This sword was lost along with his right arm, after Finn's encounter with his father in "Escape from the Citadel". Despite this, the sword was still part of him until "Reboot". After Finn's grass sword was destroyed, he acquired the Finn Sword in the episode "Is That You?". The blade was created when Finn interacted with an alternate Finn from the past, creating a paradox. Finn first uses the sword in "Dentist". When the glass on the Finn Sword was broken by the Grass Sword, Finn stops using it and instead uses the Root Sword. The Finn Sword makes a return in "Preboot" and "Reboot", however at the end of the two-part episode it merges with Finn's grass sword and creates Fern, making Finn lose his arm again, and permanently destroying the Finn Sword. The Night Sword was created by Peppermint Butler in "Marcy & Hunson". it was given to Finn to protect himself from Princess Bubblegum's family. The sword was said to be very powerful, and it contains dark magic from the Nightosphere. It has a demonic eyeball that reveals a compass in the middle of the crossguard.

In "Conquest of Cuteness," Finn was shown to have a crossbow. He uses a different one in "The New Frontier," although it appears he is less proficient with it than with a sword.

Personality and traits

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 "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 ant 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 and a consistent drive for righteousness—to "do the right thing."

Finn, like his brother Jake, 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.

Abilities

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 of 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.

Mental

Fighting Style

Finn has obtained immunity to electricity thanks to magic spring water in " Flute Spell ".This ability seems to have stuck with him as we see him display the weakness of electricity in " Preboot " against a giant electric eel and again in " The Light Cloud ' against the Great Guardian.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 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.

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 handicrafts. 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

Miscellaneous

Temporary/Magical

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.Finn is very good at playing a video game called, 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

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.[8] 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."[9] 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.

Age

Finn is twelve years old at the start of the series and progressively grows older relative to the passing of time in real life.[10] As of "Mystery Train" (March 14, 2011), he is thirteen years old. Finn is shown going through puberty throughout the series. This is seen whenever when he screams as his voice cracks. Finn's voice is noticeably deeper at fourteen than it was at age thirteen 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), Pendleton Ward stated that Finn was fourteen.

Finn was later confirmed to be fifteen years old in the second half of Season Five, according to Adam Muto.

In "The Comet," he is revealed to be sixteen years old.

Finally, in "Seventeen," he turns seventeen years old.

Relationships

Various forms

Alternate universe Finns

Farmworld Finn

Main article: Farmworld Finn

This is Finn Mertens' alternate universe form. He came into existence because of the wish that Prismo granted normal-universe Finn in the episode "Finn the Human," and he was also in "Jake the Dog." Here, he has a pointed nose, wide eyes, a robotic arm, and a Munsell blue sweater instead of a shirt. He was later the bearer of the Ice King's crown after using it to save his family.

Older/Pillow world

In the episode "Puhoy," Finn travels to a realm full of pillows where he cannot escape and eventually starts a new life, becoming an adult and elder. Elder Finn loses his right arm and replaces it with an artificial one.

Past lives

In "The Vault," along with Shoko, a few other of Finn's past lives are shown.

A Comet

As the first past life that Finn witnessed during his trance, he saw himself as a blue comet. It is unknown if this was one of the Catalyst Comets.

A Butterfly

The second past incarnation that Finn saw in the episode was his past life as a butterfly. He appears to have has blue wings with purple spots. We see this again in Come Along With Me while he is battling Fern in their dream state.

Pink Inter-Dimensional Creature

The next incarnation that he saw before he was cut off by Jake was a Giant, Pink, and glowing glob. Finn said that he thinks that the creature might have been inter-dimensional. It is possible that this might have been one of the past Candy Elementals.

Shoko

Main article: Shoko

In "The Vault," it is revealed that the strange, amorphous, ghost that has seemingly been haunting him is Shoko, his former self in a past life, who was horribly mutated before her death. Finn completes her dying wish by returning Princess Bubblegum the amulet that Shoko had stolen from her in the past.

Disguises and forms

Lute suit

In the episode "Go With Me," Finn is shown wearing a "lute suit" provided by his friend, Jake, in his attempt to convince Princess Bubblegum to go to the movies with him. It is also shown later in the episode when he tries to get Marceline to go to the movies with him.

Magic Fist

Magic Fist is the alter-ego of Finn and Jake that first appears in "Wizard Battle." He is not a real wizard; he only enters the Wizard Battle to prevent Princess Bubblegum from potentially having to kiss the Ice King on the lips as the prize for winning the battle. He wears a blue eye mask, an electric-green hood, and a large red robe. Finn is the head, while Jake is the body. See the gallery section for more images.

Cat Finn

Finn is transformed into a cat by the Grand Master Wizard when Finn forfeits the Wizard Battle; however, Finn was able to break out of it after becoming enraged by Abracadaniel's decision to take the kiss from Princess Bubblegum.

Prince Hotbod

In "The Creeps," Finn wears a black tuxedo with a blue-trimmed collar that has a split tail end. He also has a matching blue bow tie, a gray vest, a brown and tan fox mask over his characteristic hat, and brown "fancy gloves."

In the episode "Freak City," Finn is turned into a foot by Magic Man who poses as a beggar. As a foot, Finn has great difficulty moving at first, and only musters the effort to make himself fall over. Finn is upset at his physical handicap while Jake tries to make him realize that being a foot is a blessing. Finn is unconvinced and later becomes motivated to return to his original body after discovering that Magic Man has turned many others into body parts as well. After working with the other victims, Finn seemingly defeats Magic Man as the Super Freak. Magic Man restores Finn and the rest of the freaks to their original bodies.

Zombie Finn

Zombie Finn looks like Finn, and apparently appears in "Slumber Party Panic." Zombie Finn appears in the bottom left corner of the first window to be broken when the zombies break the barricades. Zombie Finn also appears in the Adventure Time game, Rhythm 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. He was most likely added as a joke or Easter egg.

Lumpy Finn

In the episode "Trouble in Lumpy Space," Finn turns into a Lumpy Space person after giving the antidote to Jake so that he can return back to his normal body.

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. Afterward, he tries to pull Jake and Marceline back into the world but stops after Hunson reverts Finn back into his original form.

Paper Plate Demon Finn

In "Daddy's Little Monster," Finn disguises himself as a demon in order to sneak into the Nightosphere. He puts on his red pajamas, cuts a paper plate and puts it on his face, and tapes forks to his hat.

Hug Wolf Finn

In the episode "Hug Wolf," Finn is hugged by the Alpha Hug Wolf on a full moon, causing him to transform into a Hug Wolf during the night. When he is in this form, he must go on a hugging spree to fulfill his hug lust. However, in the morning, he does not recall anything he did in the night before. As a Hug Wolf, Finn has shaggy gray fur, heart-shaped hands and feet, and, due to increased musculature and overall size, wears torn clothing. He is much faster and strong than his human form, while mentally he is almost completely overcome by his powerful urges to hug. He is cured when he hugs the Alpha Hug Wolf which cures her as well.

Jake's shadow

In the episode "Princess Cookie," Finn dresses in a black bodysuit and pretends to be Jake's shadow in order to get into the grocery store and take out the Chocolate Chips.

Prince Finn of the Grasslands

Although not directly used by Finn, in the episode "Incendium," Jake introduces himself as 'Baron of the Grasslands' to Flame King and calls Finn 'Prince Finn'.

Davey

In the titular episode, Finn disguises himself as "Davey" in an attempt to hide from his followers. Davey eventually evolves into his own character, possibly hinting that Finn temporarily develops a dissociative identity. However, later it's revealed that Finn was just acting. Davey is also seen in issue 60 of the Adventure Time comic showing that he was a possible previous reincarnation of Finn.

Finn Sword

The Finn Sword is created in "Is That You?" after Finn sacrifices an alternate version of himself to save Prismo. After visiting a much more elaborate version of Prismo's Time Room, created as a "Plan B," Finn makes a choice to save Prismo by creating a paradox that vaporizes his dream world duplicate. Instead of turning to dust, Finn's body turns into a sword, dubbed the Finn Sword by Prismo. Later to become cursed by Grassy Wizard's parasite, and becomes Fern, Finn's Alter-ego.

Arm occurrence

During the first five seasons, every alternate-reality, past-life, dream, and future version of Finn—with the exception of Fionna—is shown to have no right arm, or have an artificial right arm. These would include Shoko, Farmworld Finn, and the older Finns in "Puhoy," "Mortal Folly," and "Dungeon Train."

Finn does lose his arm in the episode "Escape from the Citadel," leaving just a flower from the Grass Sword. In "Breezy," it regrows from the Grass Sword's flower into a fully normal-looking arm, only with a thorn coming out from the middle of his palm; this was effectively the dormant physical form of the Grass Sword. In "I am a Sword," while Finn is fighting with Bandit Princess who is using his stolen Finn Sword, the Grass sword comes out to aid him but is accidentally thrust into the hilt of the Finn Sword, shattering the crystal which contains the alternate Finn and breaking off the end of Grass Sword in it. In "Reboot," Finn tries to prevent the Grass Sword from attacking Susan but accidentally causes it to merge with the Finn Sword and create a Grass Person, leaving Finn without a right arm once again. As of "Two Swords," Finn has a metal arm, just like the alternate versions of him. In "Three Buckets," it is revealed that this arm can transform into many different weapons. Finn loses his metal arm in the series finale "Come Along With Me," leaving him once more with just a nub where his right arm was.









The comics add to his future versions and alternate futures. In Issue 25 they expand the linear future stuff.

Bread Finn

After being turned into an egg by Magic Man in the episode "You Forgot Your Floaties," Finn falls into a bowl of flour where he was then accidentally baked into bread by Betty Grof. Finn breaks out of the oven and stumbles onto Jake who had previously been transformed into soup by Magic Man. Finn then proceeds to smash Magic Man's transmutation apparatus which disrupts Magic Man's transmutation with Glob's helmet.

Grass Finn

Main article: Fern

When the Grass Sword combined with the Finn Sword at the end of Reboot it created a humanoid Grass Finn which is shown to be Finn Sword's mind inside a grass body called Fern the Human. Finn has many doubts about it. It is technically the same Finn because the Finn Sword is Finn from another timeline turned into a sword.





Slime Finn

In order to get the Slime Princess crown jewel , Finn begins to turn into a slime during a skating competition.













Fire Finn

After attempting to save the Fire Kingdom and retrieve the fire jewel, Finn fights many times and almost gets consumed by the flame war element before finally succumbing to it.

Cultural references

Finn McCool was an adventurer and hero of Irish mythology. "Finn" is the Anglicized version of "Fionn", meaning "blonde".

Rand al' Thor is the main protagonist of Robert Jordan's The Wheel of Time series. Finn's abandonment as an infant on a mountain to be raised by step-parents is similar to Rand's origin.

series. Finn's abandonment as an infant on a mountain to be raised by step-parents is similar to Rand's origin. Tyr the One-Handed is the Norse god of war, sometimes equated with Mars. He lost his hand to Fenrir, the great wolf sired by Loki. This is another connection to Rand al' Thor who is also modeled after Tyr.



Production notes

In the original short, Finn was named "Pen." In Issue 9, it is revealed that Finn had been called "Pen" in the original short because of his love for pens. Although originally, he was most likely named after the creator of Adventure Time, Pendleton Ward. A future Finn then takes his red sleeping bag when he and Jake leave to help Lady Rainicorn, also leaving a note of advice telling Finn to use his real name. This, however, is most likely non-canon.

In the pilot, Finn is voiced by Zack Shada. However, in the series, he is voiced by Zack's younger brother, Jeremy Shada. Jeremy Shada can make Finn's voice crack when asked during episode recording to better represent his youth and growth.

In the original storyboard of "The Lich," it is revealed that Finn's father was unlawfully imprisoned years ago in the Crystal Citadel, which houses the most dangerous criminals from other dimensions. This does not appear in the final product; Finn's father's existence is not revealed until "Billy's Bucket List" and is not seen until "Escape from the Citadel."
