But in the episode Go with Me he sang to PB 'This is my lute suit' his voice was not perfectly tuned. He can sometimes rap along with Jake.

He also can make his arms and legs bend in inhuman ways, as during the Science Dance and when he uses "spaghetti limbs" (waving his arms and legs, which Jake can also do). In "The New Frontier," it's shown that Finn can make fire only with his hands. Finn is very tolerant to pain as shown in "No One Can Hear You" when the stag broke his legs; he just says, "Whatever." Also, in "The Lich", he was able to break the Enchiridion on his knee.


Finn has displayed many other impressive abilities in handicraft. He has some origami skills, as shown in "Ricardio the Heart Guy," in which he makes Princess Bubblegum a paper crane, as well as in "Marceline's Closet," in which he makes a paper airplane. In addition to that, Finn is shown to be able to construct a sculpture (of the Candy Kingdom) from his saliva, which was also made for Princess Bubblegum in "The Real You." Finn is also somewhat gifted at constructing simple machines, such as the catapult in "The Witch's Garden." Finn writes and draws with his left hand and occasionally with both hands at the same time. He additionally handles his sword with his right hand, suggesting he may be ambidextrous, able to use both hands with equal skill.



They have a good relationship together they are room mates and best buds. He helps Finn defeated Monsters but can sometimes be stubborn. They are raised together duo the strong relationship they had. Jake is like a sidekick to him as seen in defeating many monsters. 

Princess BubblegumEdit

Finn had a crush on PB when he was little and finds a way to impress her. Princess Bubblegum is kinda also likes him. Finn becomes protective when the Ice King likes to kidnapped her. He hopes that he can win the heart of Princess Bubblegum. He was rejected in the episode Incedium and was deeply depressed. He made a shrine out of her, when Flame Princess went to the Tree House she become depress that caused the fire, when the PB's picture was burned Finn said 'Who did this, i'll kill you!' which when he saw that it was girl and he said he had a crush on Flame Princess, it may be possible that he might have moved on or was just distracted. When he had a lock of PB's hair he carry it when BMO and Jake are not around. In the episode Mortal Recoil that he likes a lot since his childhood. In the episode Too Young she said to Finn 'I wanna stay with you' admiting that she might have a crush on Finn. In the same episode, PB and Finn kissed and after the PB went back to her normal size Finn want to hug her some more. 

Lady RainicornEdit

In the episode My two favorite people they had spent more time together. Finn was impress when Lady rescue Finn through the evil Lake Knights. Lady Rainicorn can understand english but maybe she dosen't want to speak it.


In the episode Evicted Finn quickly befriends Marceline the Vampire Queen, as he learns that her seemingly evil ways are just playful teasing. A rowdy and adventurous character, Marceline and Finn share the same vigor and thirst for danger. One of the key reasons why they managed to forge a friendship is that Finn saved her life in "Henchman" when Jake exposed her to direct sunlight and threw garlic at her in a misguided attempt to save his friend Finn. In the same episode, Finn, in an attempt to convince Jake of her generally wholesome ways, calls Marceline "a radical dame who likes playing games." As previously stated, Marceline loves to mess with Finn's head. Despite Jake's fear of Marceline (and of all vampires), Finn enjoys spending time with her so that they can be "awesome together." In "Go With Me," Finn asks her to go to "Couple's Movie-Night," but only as a friend. Being (mutually) disgusted to the point of vomiting by the idea of kissing (although ironically she has kissed him on the cheek at least twice), Marceline has no interest in dating Finn. In "Marceline's Closet," he accidentally sees her naked when Jake tells him to see if the coast is clear for them to get out of her house, causing him much discomfort.

Ice KingEdit

As the story's recurring antagonist, Ice King and Finn are frequently at odds. Finn is prone to impatience and quick aggression around him but can show him sympathy, as in "When Wedding Bells Thaw." However, Finn's aggression never outweighs his compassion, honor, and respect for life, as evidenced when he refused the opportunity to slay Ice King as Billy had slain the Fire Count. Similarly in "Mortal Recoil," Finn, albeit grudgingly, trusted and united with Ice King against their common enemy of the Lich-possessed Princess Bubblegum. Further contributing to their differences, Ice King competes with Finn for Princess Bubblegum, until the closing scene of season two. This mutual attraction for Princess Bubblegum can be clearly seen in "Mortal Folly," where Ice King continually pesters Finn for consent to wed Princess Bubblegum. Upon Ice King's saying, "It's not like you wanna marry her," Finn blushes and hurls a rock at Ice King.

Although Finn and the Ice King started out as bitter rivals, their relationship progressed to a friendly rivalry, then an odd friendship in its own right, and finally a genuine friendship.

The Ice King does not really hate Finn and Jake, as he only fights with them because they are opposing each other in terms of morals. He frequently tries to be friends with them (in his own, misguided way) and has willingly made alliances with them. In the episode "Still" The Ice king freezes Finn and Jake so they can have "bonding time." It was shown in "Hitman" that while Finn and the Ice King are rivals, they are not enemies, and don't harbor any real malice towards each other. The Ice King made it clear that he doesn't want to kill Finn- the most he would do is punch him in the belly and make him vomit up his lunch. At worst, they are battling rivals, as Finn openly disapproves of the Ice King's habit of stealing princesses and causing mischief. At best, they are playful rivals, even friends. In "Holly Jolly Secrets II," the Ice King has a locket with the pictures of Finn and Jake. Near the end of the episode, the two are shown snuggled up side-by-side by a roaring fire, wearing ugly Christmas sweaters. Finn's attitude towards the Ice King has softened since discovering the tragic secret of his origin, and his compassion for people in distress outweighed his petty squalls with him enough to be his friend.


BMO lives with Finn and Jake in the Tree Fort. He serves as their living video game system, film editor, camera, and many more portable electric items. He appeared in the eighth episode of Adventure Time, so it is obvious he has been with them for a long time. In "Video Makers," BMO records the footage requested by Finn and Jake, although they disagree on what genre of movie it will be, so they leave him a note that tells him to keep only the best footage and present it at the Movie Club. He ends up bringing them together by using both the action and comedy/romance footage and singing his BFF Song, so it appears he doesn't take sides with either of them. In "Incendium," BMO's video game music inspires Finn to sing All Gummed Up Inside, then BMO helps watch him while Jake courts Flame Princess, and also pulls a kancho prank on him.

Flame PrincessEdit

Finn first meets Flame Princess at the end of the episode "Incendium." During the episode, Jake had been posing 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. He is surprised to see it's Flame Princess. 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!" Flame Princess blushes. She 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." showing that he may be in love with her.

In the continuation episode, "Hot to the Touch," she officially becomes Finn's new love interest. He asks Jake to help him find her, saying that he "peeped beyond her burning gaze" and that "she ain't evil," and the two run out to look for her. They spied her by a pond and hid behind the bushes to watch her. Finn affectionately likened her to "the steam off a puppy's nose searching for ham in snow" and "a cute little flower." When she curiously dips her hand in the pool and jumps back in pain, Finn rushes to her aid, surprising her. Finn admits to Flame Princess that he really likes her and they should be together, which causes her to glow brighter and makes small fires appear around her. Finn was surprised with the fire getting near him, so he tried to put them out, not knowing that by putting out the flames he was hurting Flame Princess. Angry and confused, she ran again and the brothers chased after her, then she ambushed them. However, the attack does not last long, and Finn confuses Flame Princess by trying to compliment her while she is trying to kill them. He then tries to explain his feelings again which causes her to blush, but she resists. Upset that when Finn makes her glow brighter, he puts it, she warns him that he "should not toy the emotions of a fire elemental." Flame Princess says that fire's purpose is to burn and proclaimed that this land (Goblin Kingdom) will be her own Fire Kingdom. Finn tried to convince her not to do it.

She refused and cast a wall of fire to back down Finn and Jake. When they flew to Goblin Kingdom with fire-proof suits, Flame Princess attacked them with fireballs but they had no effect. She again shoots another fireball at Finn, but this was deflected and instead hit a cart. Jake extinguished the cart's flames, consequently hurting Flame Princess once more. Finn distresses that he doesn't want to hurt Flame Princess, but his morals say he must help the citizens of the Goblin Kingdom. Neptr, thinking he's helping, engages the foam blaster to extinguish her. However, Finn manages to stop Neptr from directly hitting Flame Princess and instead he hits Jake and a few of Flame Princess' flames, hurting again Flame Princess. Flame Princess then gets extremely angry and proclaims, "That is the last time you hurt me," and grows into her beast form, a towering human-shaped fire. A fiery tear from Flame Princess' right eye is revealed that she was harmed both physically and emotionally. Finn shouts, "No more! No more!" and literally rips himself out of his own suit and stands on top of it, shouting out to Flame Princess. However, he is ignored.

Finn, angry and upset that he can't "just like a girl," begins to cry. A tear of his falls on the flames of Flame Princess, stinging her and catching her attention. Flame Princess watches Finn cry, confused and amazed, then stops her flames and approaches him. She says that now she believes that Finn is a Water Elemental because he "creates water," or cries. Flame Princess says that no matter how much they like each other, they can't be together because they are of conflicting elements. Finn tries to explain that he isn't, but Flame Princess has trouble understanding the concept and says even if they liked each other, they would only hurt each other. Finn replies, "No, I can take it. I mean...we can try." Flame Princess glows, touched that he "would defy nature for" her. She hugs him, and although he smiles for the first few seconds, Finn begins to burn up and pushes her away. Flame Princess then bids him goodbye.

not count as "tier two." Embarrassed, Jake then gives Finn the idea to write her a "sappy poem." Finn also gets angry at Princess Bubblegum for wanting him to stop seeing her. Then, when Jake is convinced what would happen if Finn kisses Flame Princess, he and Princess Bubblegum try to stop it, but arrive to see them already kissing. When Flame Princess falls into the earth's crust due to her instability, Finn goes in to save her, with Jake cutting off her oxygen supply.

In "Ignition Point," Finn and Jake go to the Fire Kingdom to retrieve Flame Princess Scented Candles. In "Reign of Gunters," Finn takes the advice of a dating book called Mind Games and tries to act more mysterious, claiming he needs to keep all the ladies in a state of confusion; that way, he has "options in case Flame Princess doesn't work out."

In "All the Little People", when Finn put the little Flame Princess and little Finn together, little Finn approached her, and they smiled at one another. They divided a cookie and began eating it together.
