Finn

**Finn Mertens** (full title: Finn the Human and formerly known as Pen in the original short) is the main protagonist of the Cartoon Network series *Adventure Time*.

## Personality

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. But at the end of "Dream of Love," Finn was not grossed out by Tree trunks and the pig kissing.

Finn’s aspirations to be 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 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").

Many aspects of Finn's personality are shrouded in mystery. In the episode "Rainy Day Daydream," it was shown that Finn believes "imagination is for turbonerds who can't handle how kick butt reality is," showing Finn not only accuses imagination users as turbonerds and believes life is fantastic. Finn then refused to use his imagination until he had to reactivate Jake's "bombastic personality" in his imagination land, (which was just a basic gray and white empty plane hinting that Finn isn't very imaginative but that was contradicted in "Power Animal" when the gnomes harnessed the energy from Finn's imagination) which was inhabited with a few dainty creatures such as Bellamy Bug who represented Finn's secret desire to be civilized (that he will not admit to). Finn's imagination was than powerful enough to effect the real world (like Jake's but to a lower degree) and turn on Jake's imagination.

Finn can occasionally be a little self-centered such as in "Freak City." Finn can also be very stubborn, such as in "Memories of Boom Boom Mountain," "Rainy Day Daydream," and especially in "Another Way." Finn can also be easily tricked, as in "The Eyes" when Jake convinced 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 he immediately feels guilt and remorse and apologizes when he can. Finn prefers to do work and not take the easy way out ("Business Time").

## Trivia

* 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 "Ocean of Fear," Finn is revealed to be thalassophobic, meaning fearing oceans or seas. Finn has no problem swimming in "Business Time," "My Two Favorite People" and "The Witch's Garden", however, because his fear is specific to the ocean, not small bodies of fresh water.
* In "Marceline's Closet," Finn is shown to be terrified of spiders.
* Finn technically is still the King of the Goblins; the goblins believe his scapegoat, Whisper Dan, to be him.
* Finn has a fictional female counterpart: Fionna.
* One of Finn's catch-phrases is being "all about" something. In "Freak City," Finn says he is "frickin' all about sugar". Yet, he also explains that he is even more "all about feeding hobos." In "The Real You", Finn shouts "I'm all about stupid!"
* In "Dad's Dungeon," it's revealed that Finn cries rarely; only in such devastating situations, as death or being repeatedly rejected by his love, Princess Bubblegum, does he cry.

* In "Jake vs. Me-Mow," Finn carries his adoptive mother's music box in his pack and knows her lullaby by heart.
* Finn seems to speak Latin (as evidenced 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.
* Finn has coulrophobia, or fear of clowns, as shown in "Another Way".
* Stormo is a creation partially made from Finn's DNA from the episode "Goliad."
* Finn can defeat The Lich without using his pink sweater or without the jewelry and without the gauntlet because he realized that the ultimate weapon against The Lich is the power of "liking someone a lot."
