Finn Mertens

### Signature

**Finn** (**the Human**, **Pen**, **P-G-8-7**) **Mertens (A Pibby corrupted example)** is the overall protagonist of *Adventure Time*. This particular Finn is the one featured in seasons 1 - 2, as his arm remains (his arm would eventually be replaced by a robotic one) and he wields the Scarlet sword.

Due to the unstoppable entity, the Darkness, takes over multiple cartoon series, Finn and his adoptive brother/best friend Jake the Dog become servants of it, both seen attacking the rebels Pibby, Melira and Beta-Kid.

## Appearance

### Body

Finn is a long Caucasian teen with four fingers and remarkably long blonde hair, missing few teeth.

### Clothing

Finn wears a blue shirt and darker shorts with a (dark-)green backpack on at most times (the backpack is not seen in *Learning With Pibby: Apocalypse* so far). He wears black shoes with large white socks and a white bear hat covering his ominously long hair.

## 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 "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 the 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.

Now changed by the Darkness, Finn has become a mindless minion to the substance, attacking what the Darkness thinks is it's enemy.

* Stormo is a creation partially made from Finn's DNA from the episode "Goliad."

It is possible he was intended to have learned this from Martin, as in "The Visitor" he refers to himself as Martin Mertens. "The Visitor" aired after "Dentist," but has an earlier production code.
* His Demonic Form is most likely a reference to Slenderman.
* In the episode "The Vault," it's revealed that one of Finn's past lives was a comet. This could have some connection to the Catalyst Comet. This was confirmed in "The Comet," as the Catalyst Comet was, in fact, one of Finn's past lives.

* 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.

	+ This is another connection to Rand al' Thor who is also modeled after Tyr.

* 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.
