Finn The Human
Quotes: ''Mathematical!', ''I'm not trying to. I just like you. I think I... I think I like like you. Listen, when I look at you my brain goes all stupid, and I just want to hug you and sit on the couch and play BMO with you. I can't explain why, but I never felt this way and I think we should be together."
Friends: As housemates, brothers and best friends (homies), Finn and Jake share a very deep and strong bond. Having been raised together by Jake's parents, the duo share a relationship similar to that of siblings, with Jake acting as Finn's older brother.
BMO lives with Finn and Jake in the Tree Fort. It serves as their living video game system, film editor, camera, and many other portable electric items. Finn and Jake seem to take on parental roles when it comes to BMO, such as taking it to soccer practice or disciplining it when it misbehaves.

Though he initially considers her an enemy in her debut, "Evicted!", Finn quickly befriends Marceline the Vampire Queen, as he learns that her seemingly evil ways are just playful teasing in "Henchman." A rowdy and adventurous character, Marceline and Finn share the same vigor and thirst for danger.
Finn had a rather obvious crush, which he denied before the events of the episode "Wizard Battle", on Princess Bubblegum, whom he occasionally calls 'Peebles' and other nicknames out of affection. In "Too Young", she shows much affection towards Finn. Based on her actions, this may show that this might be PB's actual feelings for him if she was at that age at the time. To complete her re-aging process they share "a whopping love-hug" and a kiss. Afterward, she can only remember the hug. When Finn wants to hug her again she shays that 'it was, like, five years ago'. Finn feels beaten afterwards, but a pep-talk from Jake brings his spirits back up.
Flame Princess is Finn's ex-girlfriend. He first meets her at the end of the episode "Incendium". During the episode, Jake poses as Finn trying to court her because he believed that Finn, depressed after being rejected again by Princess Bubblegum, needed a new love interest.
However, when Flame Princess's father tells Jake that she is evil, Jake tells her (disguised as Finn) that he doesn't like her, which causes her to become confused and angry and attack him, following him back to the tree fort where the real Finn is. She starts a fire in the house which burns the pictures in Finn's shrine to Princess Bubblegum, and he becomes enraged and runs to see who ruined his shrine. When she accidentally lights the liquid pyrotechnics left behind by Princess Bubblegum and douses her fire, he saves her and brings her into the house. When she regains consciousness, Flame Princess yells at him, "You! What's wrong with me, huh?! You don´t like me?!" and Finn states, "I like you!" This statement, despite Finn never knowing Flame Princess before, is evident of "love at first sight." Flame Princess blushes, then slaps Finn and warns him never to mess with her again, and flees the tree house. After she slaps him, he immediately wanted to know who she was. He then told Jake, "Dude, I think I have a crush."
