Finn the Human
Finn Mertens, also known as Finn the Human, is a fictional character in the American animated television series "Adventure Time" created by Pendleton Ward. He also appeared in the spin-off series "". He is voiced by Jeremy Shada in most appearances. The character made his debut in the original pilot, where he is named Pen and voiced by Zack Shada, Jeremy's older brother. Jonathan Frakes voices Finn as an adult in some appearances. Prior to the start of "Adventure Time", Finn was adopted as an infant by two anthropomorphic dogs named Joshua and Margaret, who found  him in the woods. His best friend and adoptive brother Jake the Dog (John DiMaggio) accompanies him on many of his adventures in Ooo, the fictional world that the series is set in. The mystery surrounding Finn's origins and whether he is the last human left in Ooo is a major part of the character's narrative arc. Later in the series, it is revealed that there are other humans still living in Ooo and that Finn's parents Martin and Minerva came from a community of survivors living on a chain of islands. Finn has received critical praise  for his development and coming-of-age narrative, which saw the character mature from a boy into a young man. Adam Muto, former showrunner for "Adventure Time", has stated that Finn's progression from an aggressive and reckless boy into a more mature person was one of his favorite character arcs to write. A gender-swapped version of Finn called Fionna appeared in the third-season episode "Fionna and Cake", and is the main character of the spinoff series "". Design and voice acting. Series creator Pendleton Ward has stated that he wrote Finn, and "Adventure Time" as a whole, as  though he were playing a session of "Dungeons & Dragons," a tabletop role-playing game. Ward commented that Finn's motivations are noble, with a desire to "slay monsters, explore dungeons, find loot." Ward spent much of his childhood at home, and he described his "[indoor] adventure experience" as inspiring Finn and Jake the Dog's adventures. Early on in the development of the show, Ward had intended for Finn and Jake to be nomads who lived in tents. However, this was changed to having them live in a permanent home at Cartoon Network's request. The character first appeared in  the short film "Adventure Time", which centers around rescuing Princess Bubblegum (Hynden Walch) from the evil Ice King (John Kassir). This short aired as part of Nickelodeon's "Random! Cartoons" showcase in 2008. Zack Shada voiced the character, then called Pen, in the short. Zack Shada was too old for the role when the series was picked up by Cartoon Network, and his younger brother Jeremy, 12 years old at the time, auditioned. According to Jeremy Shada, the showrunners did not at first realize that he was Zack's younger brother. He said that: "they just thought they got lucky  with someone that sounded like the original." Shada's voice noticeably cracked and changed during the filming of Adventure Time as he was undergoing puberty. Ward decided that Shada would not be recast when his voice changed. Instead, the character of Finn was gradually aged as Shada's voice naturally deepened, and the themes of the show matured with the character. Older versions of Finn appear in several episodes of the show. Jonathan Frakes voices two alternate adult versions of Finn in the season 5 episodes "Puhoy" and "Dungeon Train". Like other "Adventure Time" characters, Finn is drawn with rubbery  limp noodle limbs and a simple but expressive face. He has several missing teeth, which Ward explained as being due to the character never having been to a dentist. He typically wears a signature white bear hat, and form-fitting clothing. Finn's visual design resembles Bueno the Bear, another character created by Ward. Finn and Bueno share some other similarities, including an enjoyment of beatboxing. The show depicts Finn dealing with the struggles of adolescence and coming to terms with the complexities of life. Over time, the show's creators decided to further develop Finn's backstory, including his  parents and whether he was truly the last human left in Ooo. A major theme of the series is that Finn begins to see the world in more nuanced terms, rather than the naive outlook he demonstrated in earlier seasons. Although many of the show's conflicts were about good versus evil at the start of the series, they become more complex as it progresses. "Adventure Time" composer Tim Kiefer said that the show had gradually became an exploration of the "Hero's journey", through Finn. In the early seasons of the series, Finn is enthusiastic and readily resorts to  violence to settle conflicts. About this aspect of Finn's character, Ward said that he chose to "add a little wrath" to add depth to the character. By the end of the series, Finn is much more reserved. "Adventure Time" showrunner Adam Muto stated that this theme is part of the reason why Finn did not have a sword for much of the finale. Muto said that this story arc made Finn had one of the most satisfying characters for him to write on the show. Appearances. Finn the Human is the main character of "Adventure Time" and often appears  alongside his best friend and adoptive brother Jake the Dog. Finn was adopted by Jake's parents Joshua and Margaret as an infant. He is originally believed to be the only human left in Ooo after the "Great Mushroom War", a mysterious conflict that occurred 1,000 years prior to the start of the series. It is later shown that he was born on Hub Island, part of an isolated archipelago populated by humans. Finn's biological father Martin (Stephen Root) is a conman, while his mother Minerva (Sharon Horgan) is a doctor. Martin fled Hub Island with an infant Finn  after being found by disgruntled acquaintances from his past. He was separated from Finn, who was left on a raft floating towards the mainland. In the first-season episode "The Enchiridion!", Finn and Jake complete a series of challenges to win the Enchiridion, a legendary handbook for heroes. In "His Hero", Finn meets the legendary adventurer Billy (Lou Ferrigno), who unsuccessfully tries to convince Finn to give up violence. Finn and Jake go on a quest to find the Lich (Ron Perlman), an ancient undead king, in the second-season episodes "Mortal Folly / Mortal Recoil". The Lich returns in the  fourth season finale "The Lich", and kills Billy. After taking control of Billy's body, the Lich attempts to trick Finn and Jake into giving him the Enchiridion. Billy's death profoundly impacts Finn, as shown in the season five episode "Billy's Bucket List". Finn experiences other alternate lives and versions of himself throughout the series, all of whom have lost their right arm. This foreshadows Finn's eventual loss of his arm in the season 6 premiere "Wake Up / Escape from the Citadel". In "Escape from the Citadel", Finn discovers that his father Martin is an inmate of  the Citadel, a multiversal prison reserved for those who commit a "cosmic crime". Finn and Jake go to the Citadel to find Martin. The Lich arrives and attempts to free its prisoners so he can use them as an army. Finn loses his arm when the Lich destroys the Citadel, and Martin escapes. Finn is changed by the loss of his arm and becomes disillusioned with his father. A flower blooms from the stump where Finn's arm used to be, and eventually grows into a new arm. He loses his control of his regrown arm, which transforms into a  grass doppelgänger called Fern in the eighth season two-part episode "Preboot / Reboot". The violent and reckless Fern acts as a foil to Finn, who has matured over the course of the series. Finn later attempts to redeem Fern, who shares many of the shortcomings Finn had when he was younger. In the following episode, "Two Swords," Finn is fitted with a robotic arm by Princess Bubblegum. The miniseries "Islands", which aired as part of season eight, sees Finn search for the surviving humans who left the continent and moved to an archipelago centuries after the Great Mushroom War. Finn  meets his mother Minerva, a doctor who has uploaded her mind to a network of robots. Minerva tries to force Finn to stay on the island where she can protect him until Finn convinces her to let him go. He invites the humans to return to Ooo, but they choose to remain on their islands. In the series finale "Come Along With Me," Finn and Jake help Princess Bubblegum fight her dictatorial uncle Gumbald. Realizing that violence is not the answer to the conflict, they ally with Gumbald to defeat the evil deity GOLB, who is intent on destroying Ooo . Finn's robotic arm is snapped off when he and the other protagonists are eaten by GOLB. GOLB is defeated, although Fern dies in the aftermath. Finn promises to plant Fern's seedling in the ruins of the treehouse, which has been destroyed. The seedling grows into a new treehouse, with a grass sword inside. Finn and Jake are shown relaxing on a beach. The "" special "Together Again" takes place sometime after the end of the series, when Finn has died of old age. He then journeys through the Dead Worlds to be reunited with Jake, who is also deceased . After reuniting with Jake in the afterlife, the two choose to reincarnate back into the living world. Others.

A gender-swapped version of Finn called Fionna  appeared in the season 3 episode "Fionna and Cake", voiced by Madeleine Martin. Fionna inhabits the land of Aaa, a fictional world created by the Ice King (Tom Kenny) as a form of in-universe fanfiction. The concept for Fionna and Cake came from drawings made by "Adventure Time" storyboard artist Natasha Allegri. The tomboy-ish character of Fionna has much the same personality as Finn and has similar struggles with romantic attractions. Both Fionna and Cake the Cat, the alternate version of Jake the Dog, became popular with "Adventure Time" fans. Fionna later appeared in the fifth-season episode  Bad Little Boy, the sixth-season episode "The Prince Who Wanted Everything", the eighth-season episode "Five Short Tables", and the ninth season episode "Fionna and Cake and Fionna". Fionna will star in the upcoming spin-off series "". Characteristics. Personality and traits. Finn is a teenage boy with a childlike personality, boyish enthusiasm, and a love of adventure. He is 12 years old at the beginning of the series but ages throughout the show and is 17 by the series finale. He is talented at beatboxing and sword fighting. Finn is prone to outbursts of phrases like "Mathematical!" and "Algebraic !". He develops thalassophobia in the season one episode "Ocean of Fear" but overcomes his fear of the sea in "Billy's Bucket List". In the fifth-season episode "Red Starved", it is implied that Finn is color blind. Finn is shown to be enthusiastic and reckless, although he becomes more reserved over the course of the series. He is motivated by a desire to live by a heroic code and a thirst for adventure. Having once been lost in the woods as a helpless infant, he "vowed to help anyone in need, no matter how small their problem". Many of  Finn and Jake's early adventures revolve around them exploring the land of Ooo and battling monsters. Finn's life with Jake is modelled after the archetypal knight-errant, as they frequently explore dungeons, fight evil creatures, rescue various princesses, and save the world. Relationships. Finn has a close relationship with his adoptive older brother Jake the Dog, an anthropomorphic dog with the ability to change shape. At the time of the series, Finn and Jake live together in a treehouse. Their relationship is at times strained by the differences in their maturity and outlook on life. Jake often finds  himself frustrated by Finn's childish antics and infatuations with various princesses. Finn's life revolves around adventuring and fighting monsters, while Jake likes to pursue more varied interests. After Jake ends up in a relationship with Lady Rainicorn and has five children with her, his focus shifts towards being a father. This creates distance between them, but they remain close friends and Finn enjoys being an uncle. Finn is also friends with BMO (pronounced Beemo), a sentient handheld game console who is Finn and Jake's roommate. Finn creates the robot NEPTR (Never Ending Pie Throwing Robot) as part  of a prank, but NEPTR soon becomes a friend to him. Finn ends up developing a close friendship with Marceline the Vampire Queen (Olivia Olson), despite her initial role as an antagonist. Finn is shown to have an unrequited love for Princess Bubblegum throughout much of the series. He and Jake frequently have to rescue Princess Bubblegum from the obsessive Ice King. Finn's past life as Shoko, an orphaned thief who befriends and then betrays Princess Bubblegum, influences his present-day infatuation with Bubblegum. Finn's friendship with Bubblegum becomes more distant as the series progresses. Finn begins dating  Flame Princess (Jessica DiCicco) in the third-season finale "Incendium", after realizing that Princess Bubblegum is too old to be compatible with him. Although Flame Princess' fiery nature makes their relationship difficult, they try to make it work. Finn and Flame Princess eventually break up. Finn's relationships with both Princess Bubblegum and Flame Princess cause him to have to deal with rejection and reconciliation, and he emotionally matures as a result. Finn has a complex relationship with his biological father, Martin Mertens, who is shown to be a scoundrel. In season 6, Martin reveals to Finn that he was  forced to abandon him as an infant after reaching a crossroads too dangerous for an infant and that he always meant to return for him. Adam Muto said that they did not want Finn to be a "carbon copy" of Martin since he had an adoptive father in Joshua. Muto said they wanted to "embrace the idea of Martin being as and dishonorable as Finn is heroic". The season six episode "Breezy" deals with Finn's depression after losing his arm, being disappointed by his father, and breaking up with Flame Princess. Finn makes out with various princesses in an  attempt to feel something positive but is left emotionally unfulfilled. During the episode, he explores a complicated relationship with a honeybee named Breezy, who falls in love with a flower sprouting from where his arm was cut off. Both Finn and his mother Minerva are shown to be selfless and dedicated to helping others. However, Minerva is fearful and overprotective due to the losses she has experienced, in contrast with Finn's adventurousness. Upon reuniting with Finn in the miniseries "Islands", she is both alarmed by his dangerous lifestyle and proud that he devotes his life to helping others. She  attempts to trap Finn on the island so that he will be out of harm's way. After convincing her to release him, Finn leaves her behind and returns to Ooo, though the separation causes him grief. Various critics have interpreted the portrayal of Finn and Minerva's opposing views as a commentary on the repression of emotions, overreliance on technology, the sacrifice of freedom in exchange for safety, an exploration of Nietzschean philosophy, and an allegory for "American self-absorption." Reception. Finn the Human's character arc has been highlighted by critics for its honest portrayal of adolescence and  universal struggles associated with coming-of-age. Brandon Zachary of "Comic Book Resources" described "Adventure Time" as "one of the most expansive fantasy series in modern history, centering around a kind but unassuming boy growing into a noble young man." Writing for "Vox", Emily VanDerWerff called the series "this era's finest coming-of-age story", mentioning how Finn grew "from boy to almost-man, an adolescent who's slowly figuring out how to be both a good friend and a good person." Oliver Sava of "The A.V. Club" praised the episode "Breezy" for its relatable depiction of Finn's  developing sexuality and his search for emotional fulfillment. Finn's story arc as the last remaining human and his eventual discovery of other humans has been praised by critics. Zach Blumenfeld of "Paste" compared Finn's rootless and heroic existence to the passionless, technology-dependent lives of the other human survivors in "Islands". Blumenfeld considered Finn to be an example of Friedrich Nietzsche's hypothetical Übermensch.[Finn] affirms life as it happens (both the good and the bad), constantly creates a value system and exists completely unfettered by society or the past. [...] He's grown up without the weight of human  history and custom, has guided his own way through a flood of adolescent emotions and has become a hero in a dangerous land of his own free will. His moral code, once crafted in the image of his idol, Billy, is now of his own making. The character also became extremely popular among "Adventure Time"'s fanbase. In 2019, Rich Goldstein of "The Daily Beast" commented on Finn's popularity among cosplayers, saying "Halloween nights and comic conventions of the last few years have seen an increase in the number of children (and adults) all over the U.S. who wore  Finn and Jake costumes." John DiMaggio recalled "walking around at conventions and seeing everybody wearing their Finn costumes and their Jake costumes and how the characters endeared themselves to people". A float in Finn's likeness was included in the 2013 Macy's Thanksgiving Day Parade. Finn's narrative and impact on younger audiences has been compared to that of Harry Potter, the titular character in J. K. Rowling's book series of the same name. In particular, Finn's growth from a child to a young man was compared to that of Harry Potter, with Darren Franich of "Entertainment  Weekly" saying that Finn "[aged] with his audience like last decade's "Harry Potter" kids."
