Finn's weight seems to fluctuate between episodes, with him seeming chubbier in some instances than others. Pendleton Ward stated on the "In Your Footsteps" commentary on the Season 4 DVD that his weight depends on how active he is adventuring, along with his diet, so it changes frequently. Although at times impulsive, aggressive and short tempered, 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."

The episode starts off with Finn and Jake running through the candy forest to find the swimming hole Jake mentioned to Finn. Jake says that they should race to the swimming hole, then Finn argues that Jake is cheating because he has to take his clothes off, and reveal his red-and-white underwear. Jake trips and falls and Finn catches up, in just his underpants, and throws his clothes to the ground and throws his hat near a flower. Finn and Jake then jump into the pond to swim. While they are swimming, the flower touches Finn's hat, and shines a bright light inside it. Finn and Jake start swimming in circles to create a swirl. Bad Little Boy," " The Prince Who Wanted Everything," " Princess Day," " Evergreen," " The Diary," " Friends Forever," " Be Sweet," " Orgalorg," " Varmints," " Cherry Cream Soda," " Broke His Crown," " Lady Rainicorn of the Crystal Dimension," " Five Short Tables," " Daddy-Daughter Card Wars," and " Ring of Fire" are the only episodes where Finn did not make an appearance. Cole Sanchez Little Dude is the name given to Finn's hat when it comes to life in the episode " Little Dude." It was given life when Finn dropped it near a flower at the swimming hole in the Cotton Candy Forest, which was growing on top of the head of the Ancient Sleeping Magi of Life Giving. The Magi had buried himself to keep things from touching him, because when they do they're brought to life, but are infused with an evil spirit.This article was nominated in the 2021 Who Would Win Tournament. They only made it to the second round, and the tournament is now concluded. As the first past life that Finn witnessed during his trance, he saw himself as a blue comet. This was later revealed to be a Catalyst Comet. [11] it is likely that, given the nature of the catalyst comet, Finn is a reincarnation of the essence of pure good, to counter the Lich’s pure evil. 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.

Little Dude jumping on people's heads to possess them is similar to the headcrab, a creature from the Half-Life video game series. 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." In " Preboot" it is revealed by the "human plus" Dr. Gross that are more humans outside of Ooo. This is further explained in the miniseries Islands, where it is revealed that roughly a thousand years prior to the main events of the series, a group of surviving humans from the Mushroom War fled Ooo on a container ship (as seen in Stakes) to escape from the vampires, oozers, and a comet. They eventually settled on a secluded island chain far from the mainland. Over the next thousand years, their community thrived and developed into an advanced technological society. While it was a veritable utopia, there were those few who occasionally grew dissatisfied with their rigidly structured lives and attempted to flee the island; these "hiders" were, in turn, hunted down and returned by specially trained "seekers." Finn, Jake, Susan Strong, and BMO went to the islands so that Finn could find out about his past and his species.
