Finn The Human
Prior to the start of Adventure Time, Finn was adopted as an infant by two anthropomorphic 1980s type 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 universal praise for his character development and coming-of-age narrative, which saw the character mature from a boy into a wise 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 Adventure Time: Fionna and Cake.
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.
Finn was always fun because he started very agro [sic] and that was fun to write for a while, but as he got older it didn't make sense to keep writing him that way. He became a mellower version of himself and more introspective and that was satisfying to follow.
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 personality, 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 progression is part of the reason why Finn did not have a sword for much of the finale. Muto said he felt that this story arc, involving Finn's progression from a violent character to a more introspective one, made him one of the most satisfying characters 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 for the time being.
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 when the humans return to Ooo for the first time in centuries.
The Adventure Time: Distant Lands 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 predeceased him. After reuniting with Jake in the afterlife, the two choose to reincarnate back into the living world together.
