Finn the Human

**Finn Mertens** (also known as: **Finn the Human**, or formerly known as **Pen** in the original short) is the main protagonist of the series *Adventure Time*.

## Biography

It is revealed in "Min & 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 seperated as a result, with Finn being sent adrift towards Ooo and Martin disappearing.

As shown in "Memories of Boom Boom Mountain," Finn appears to have been abandoned in the woods during infancy. He reveals that he made "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.

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."

Finn becomes a contestant on Cartoon Cartoon Island where he meets and falls in love with Yumi Yoshimura and he mentions in the confessional that he broke up with The Flame Princess. Yumi first tries to resist his affections, but overtime, they fall in love. They even get married in the future and have two children.

* 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 is revealed that Finn cries rarely; only in such devastating situations, such as death or heartbreak (or when he poops as revealed by Jake in Memories of Boom Boom Mountain).
* Finn and Jake frequently use math terms as catch-phrases and at times censors for curse words. However, they are shown to be terrible at math as confirmed in the episode "Slumber Party Panic." (Examples of these words include: mathematical, rhombus, algebraic and math). This has seemingly been abandoned as the show progresses.
