Jake

Jake (full title: Jake the Dog), the second protagonist of Adventure Time, is a magical dog and Finn's constant companion, best friend, and adoptive brother. Jake has Stretchy Powers, which allow him to stretch and manipulate his body, coming in handy on innumerable occasions throughout his and Finn's adventures. He is the son of Joshua and Margaret. Jake has a brother named Jermaine. Jake is 28 in magical dog years, but he rarely acts maturely. He is around 14 in human years. Both he and his girlfriend, Lady Rainicorn, share a passion for playing the viola.

Appearance
Jake's normal form is a yellow-colored bulldog with large, characteristic eyes.

He can morph into all sorts of fantastic shapes thanks to his Stretchy Powers. He also wears transparent pants made of spider webs spun by pixies which he said in the episode "Donny". He also has another pair of pants which is seen in the episode "What was Missing". When he was a puppy, he was small enough that his father, Joshua, could loom over him.

In the Animated Short, he basically was the same, but his eyes stayed the same throughout the episode, and his hands had no fingers.

Abilities
Jake's Stretchy Powers enable him to modify the size, shape, and dimensions of every part of his body. Not only can he stretch and contort himself into highly specific forms, but he can also rearrange his internal organs, and teeth. In "Evicted!" he was able to shrink and move his internal organs and blood into his left thumb. Also in "Jake vs. Me-Mow" , he enlarged his liver 51 times a dog his size, preventing him from dying from Me-Mow's poison. One frequent use of his powers is Key Hand, which he uses to pick locks. As shown in "Mystery Train," he is also able to stretch himself to "create" an entirely new person, as long as they remain connected to him. Jake can be stretched by force as seen in "Ocean of Fear," when Finn stretched Jake's ears to avoid making contact with the ocean. Pen Ward has said in an interview that Jake uses his powers lazily and doesn't know their full extent. In "The Witch's Garden," Jake claims to have obtained his powers by rolling around in a magical mud puddle as a puppy, but in an interview Pendleton Ward stated that this is not how Jake got his powers, he just could not remember.

In the episode "The Limit," Jake's Stretchy Powers are put to the test. It is revealed that while Jake can stretch his body to incredible lengths, he does have a limit. As he approaches this limit, his body becomes dangerously thin. Once his mass is distributed along a certain length of his body, it becomes difficult for him to support himself; at one point, Jake was forced to walk along the ground. If he were to stretch beyond his absolute limit, it is presumed that he would completely thin out and die.

Being a magical dog, Jake, perhaps unsurprisingly, also has an acute sense of smell, as he can apparently smell the precise location of an object miles away. He also owns a sword, a shield and an axe but seldom uses them in combat. In "Mystery Train," when disguised as the Conductor, he briefly uses a sword to fight Finn, who effortlessly defeats him. This demonstrates that Jake is not proficient in swordplay, at least relative to Finn, but that could have just been part of his birthday party possibly making him better at swordsmanship. It is then that he also displays a prowess for skateboarding, as he performs jumps, ollies, and grinds; several atop a moving train.

Jake also has a supernaturally powerful imagination (on the verge of having psychic powers) as seen in "Rainy Day Daydream." Anything he imagines becomes reality; however, only he can see his own creations, and it is shown that he can control organisms.

Jake is a skilled musician as well, particularly with the viola, which can have peculiar effects when playing certain pieces; he is able to summon snakes when he plays the first movement of "Eine Kleine﻿ Nachtmusik" by Mozart. Jake's viola is the home of Shelby the Worm and also has the word "toots" scratched on the back, which is shown in the episode "What Was Missing". Jake also plays the acoustic guitar, as seen when he plays the titular song in "Susan Strong." In "Death in Bloom," Finn describes Jake as "the musical one." However, in "What Was Missing," he breaks his viola himself, as seen in the 30-second trailer. It is also shown in "Incendium" that he can play ukulele. Jake is an average singer.

In "Freak City," Jake claims he can sense when Finn is about to cry, saying "it's like a mother-daughter thing." Apparently, Jake can also calm down Finn with his saliva.

Jake can also speak Korean, which he uses to communicate with Lady Rainicorn. In "Her Parents," he writes a note to Lady's mother and father using Hangul, the Korean writing system, and also greets them speaking in the formal Korean language.

In "Power Animal," Jake's body is filled with the souls of "a thousand partying demons," as a catch from his wish granted by the Party God. As a result, a few temporary powers where granted to him, such as the ability to fly (although, this might not have been flight, but merely a sort of homing beacon to find Finn, because Jake didn't appear to have any control over his direction). A side effect of receiving these powers was that his body began to glow, and his eyes became stars that flashed multiple colors.

In "The Chamber of Frozen Blades," Jake and Finn both gain powers similar to the Ice King by reading the First Edition: Ice Ninja Manual, but they lost their powers again after the episode is over.

Personality and character traits
Jake is generally laid-back and tends not to worry about things. He relies heavily on his powers (or Finn) to get him out of any dangerous predicament he gets himself into, which is often. He often cracks jokes at serious times, but if Finn is feeling disheartened Jake always has a lecture or a song to cheer him up. Acting as Finn's world-wise mentor, he is always willing to give input and advice about a situation, but his suggestions are usually inconsistent; they range from encouraging and helpful to ridiculous nonsense. He can be somewhat irresponsible at times, frequently leaving Finn to fight most of a battle on his own, but he always pulls through when he is needed most. Jake may be dyslexic, as evidenced by the fact that he writes backwards, as shown on his note to Finn in "Storytelling." However, Finn also writes backwards in several episodes, indicating that this may be the result of Joshua and Margaret's parenting style or a common mistake in the Land of Ooo.

Jake loves to eat. He likes junk food, especially pie and ice cream. He isn't afraid to try new foods (as seen in "Her Parents") and invents his own foods. There is little evidence of his ability to cook; for example, when he makes Korean food for Finn at the beginning of "Apple Thief," when he cooked all the food that he used to make the Everything Burrito, and he did make coffee in "Beautopia."

Jake is shown to have a very short attention span, as shown in "Power Animal". He can literally forget about a conversation in a moment, and start doing something completely unrelated, such as putting a ice cream cone in a toaster. In fact, Cinnamon Bun summarizes it quite nicely, saying, "Jake, you don't really focus at all." This is also shown in "Burning Low," when he falls asleep twice when Pincess Bubblegum is trying to explain why Finn can't be with Flame Princess, and when Finn tries to get ideas from him.

Jake can also be rather fickle at times, a prime example of this is in The Duke when he convinces Finn to blame the Duke of Nuts for turning Princess Bubblegum green and bald, but later spent the rest of the episode trying to convince Finn to confess that he did it.

Jake is very musical. He is often seen playing the viola. He has sung on multiple occasions throughout the series. Jake's most notable song occurred shortly after the House Hunting Song, when he sings to Finn about home being "where your heart is." He can play both the guitar, as shown in the episode "Susan Strong," and the ukulele, as seen in "Incendium." In the episode "Death in Bloom," Finn even says that, out of the two of them, Jake is the "musical one."

Jake is also known at being imaginative and creative, as seen in Rainy Day Daydream and his creativeness is shown by combining food like the Everything Burrito and the ice cream pizza. Even though they aren't quite great, Jake still sees them as delicious.

At times, Jake is shown to have somewhat of a dark side, entirely not present in Finn. Throughout the series, Jake makes some questionable comments and actions that come off as evil or selfish, such as in the episode "My Two Favorite People" when he laughs in an evil voice and in "Susan Strong" when he says, "We can rule them like gods. Angry gods." Another example of Jake's darker side is seen in the episode "Apple Thief," when he mentions that he used to "snatch old ladies' purses" and "hock stolen bikes." His darker side can also be seen in "Conquest of Cuteness" when he suggests squishing all the cute people instead of helping them feel better like Finn wanted to do. In addition, during the episode "Ghost Princess," Jake can be seen taking a ring and putting it inside of a skin pocket. He also had a bunch of stuff he stole hidden under his stomach flab. When he showed Finn and he confronted him about it, he simply said, "I didn't know it was wrong." And in the episode "Hot to the Touch," when Finn and Jake are flying in the robot suits NEPTR made Jake says, "I feel like I could touch the heavens, and sock angels." In "Card Wars and Goliad," displayed a short temper where he would yell or threaten someone by scaring them.

Jake is not afraid of death as shown in "The New Frontier." He is a firm believer in fate and destiny. Jake is also religious and believes in Grob Gob Glob Grod and Glob World.

Finn
Finn and Jake are best friends and adoptive brothers. They will go out of their way to protect each other. Jake watches over Finn using his stretchy powers to protect him, whether it is shielding him from rain or cold weather, or catching him in mid-fall. Jake was fully aware of Finn's crush on Princess Bubblegum. He was also very supportive when he was heartsick from her, and fully understands how much PB had hurt him. Having been raised together by Jake's parents, Joshua and Margaret, the two share a brotherly companionship. Jake often acts as a force of guidance in Finn's life, giving out whatever advice he sees best. Though they have seemingly contrasting personalities, Finn's manic hyperactivity and Jake's genuinely lazy demeanor, the pair make an excellent team and are immensely important figures in each others lives. It is known that Jake is not Finn's dog, but rather his friend and brother- as seen in "Jake vs. Me-Mow" when they refer to Jake's Mom as simply Mom. Finn treasures her music box that she used for lullabies and carries it with him in his backpack; he sees himself as their son and fellow 'puppy'. Jake can sense when he is about to cry or feeling about to cry, he said that it is like a mother-daughter relationship. He plays a lot of roles - sometimes acting like a pet dog - for example, growling at Susan Strong for almost drowning Finn, sometimes like a parental figure, giving him advice or cheering up, like in "Return to the Nightosphere."

Lady Rainicorn
Lady Rainicorn is Jake's girlfriend. According to her official bio, they get along so well because of their shared interest in the viola.

Jake is fluent in Korean, which he used to communicate with Lady. A loyal boyfriend, Jake often stops adventuring to make time for her, meeting her every day at 4:00 PM on the dot.

In "Go With Me," they are seen kissing at Couples Only Movie Night. In the episode, "My Two Favorite People," Lady also recalls a time when she and Jake ran naked through a farmer's field, causing them both to blush. This may indicate some level of intimacy in their relationship. Though they are technically almost always naked, aside from Jake's invisible pants.

Jake feels threatened by and becomes jealous when other males are friendly with Lady. For instance, Jake storms off when he misinterprets Finn and Lady's budding friendship in "My Two Favorite People." Another example comes in "Video Makers," when Mr. Cupcake flexes his muscles at Lady Rainicorn instead of acting out a wedding for Jake's romantic comedy movie. Jake says that he told him to say the lines instead of flexing out, who instead responds "I don't hear her complaining," which provokes Jake into attacking him. In "Paper Pete," Jake said he would one day want to have children with Lady Rainicorn[[File:S1e12_jake's_letter.png|thumb|294px|Jake's letter to Lady Rainicorn's parents: "To Mrs. and Mr. Rainicorn, 47 Rainbow St.

Please come exactly 1 hour early. I do not have a pet turtle.

-Jake"]].

Tree Trunks
Jake and Tree Trunks share a close relationship, which is similar to a grandmother-grandson relationship. This is shown most of the time, though there was a situation in the episode "Tree Trunks" when she kissed him several times so that he would let her help Finn. Jake appeared later with lipstick marks all over his face, and he was smiling. Later, Tree Trunks tells Finn that she'll accept his apology (Finn had earlier yelled at her) if he would let her kiss his cheek. Finn was about to decline the offer when Jake says "Whoa, let her kiss your cheek, man! It's a once-in-a-lifetime opportunity!" Other than this, there are no references of an unlikely romantic relationship between Jake and Tree Trunks, although they remain close friends.

Marceline
Jake initially has a fear of vampires, which makes him terrified of Marceline. Marceline can't help it and likes to scare Jake, but in "Henchman," Jake will not accept the fact that Marceline is not evil, and almost murders her by exposing her to sunlight. However, by Season Two, Jake seems to have accepted that she is not evil and has gotten over his fear of her, although Jake was in Finn's pocket during the events of "It Came from the Nightosphere," and because Marceline attends Finn and Jake's party in "Power Animal" and movie night in "Video Makers." In "Go With Me," Jake was arguing with her of what to tell Finn to do so he can impress Princess Bubblegum and ask her to go with him to the movies ." As shown in "Heat Signature," Jake is now friends with Marceline and visits her house to watch movies. He also is concerned when Marceline is in danger in "Memory of a Memory." They have become close friends, although Jake still holds some level of fear for her, as exemplified in "Marceline's Closet", where he is clearly trembling at the mere thought of what Marceline will do unto him and Finn at the realization that they broke into her house and invaded her privacy.

Princess Bubblegum
Jake is very aware of Finn's crush on Princess Bubblegum, so Princess Bubblegum and Jake have a rather strange relationship. They are good friends, though. Jake and Princess Bubblegum rarely speak to each other, but in Incendium PB calls him "puppy" in a sweet, baby voice even letting him rest his head on her lap, and in the episode Ricardio, Jake and PB teased Finn's love for PB. In Princess Cookie, Jake stated that he hated her because he thought it was unfair that PB didn't let him be a mailman and made him be a milkman, though it is possible he was just saying this to stall Baby-Snaps. In "Burning Low", Jake misinterprets PB's attempts at keeping Flame Princess stable as jealousy, and when she returns again looking for Finn, Jake furiously berates her for causing Finn so much emotional pain and for being a "heartless monster". After restabilizing Flame Princess, Jake notices Bubblegum's reaction to Finn and Flame Princess' "kiss" (each kissing a rock to symbolize an actual one) and mocks her for being jealous, only for PB to tell him to shut up.

Ice King
The few times Jake and the Ice King are together, they are usually enemies, as seen in "The Eyes" where Jake tries to beat him in battle. However, in "Holly Jolly Secrets Part II" it is implied that both Finn and Jake had "a fleeting moment of empathy" for him. In "Holly Jolly Secrets Part I," the episode prior, the Ice King says "You know how Jake is: 'stretch this stretch that,' blah!" implying that Jake's abilities are rather annoying to him.

Flame Princess
At the beginning of "Incendium," Jake seems to like her as a girlfriend for Finn. However, after she shows her hot-headed side (and her father calls her his "evil daughter") Jake seems to be afraid of her. In "Hot to the Touch," Jake continues to think that she is evil and tries to make Finn understand that.

Jake greatly respects Finn's relationship with Flame Princess, and does everything he can to keep it intact, including keeping his distance when the two are spending time together. Jake also defended FP when Princess Bubblegum apparently attempted to keep the couple apart. After "Burning Low," Jake no longer sees her as evil and just wants Finn to be happy.

Family
Joshua and Margaret are Jake's parents who first appeared in a flashback in "Memories of Boom Boom Mountain." Confirmed on Pendleton Ward's Formspring, Finn and Jake's parents are dead, although when or how they died has not been revealed. During his flashback as a child in the episode "Crystals Have Power", Jake was shown to have a living brother named Jermaine. Jake is often reminded of his family, as shown in "Beautopia."

Others
While Finn and Lady Rainicorn are apparently Jake's two favorite people, he has a number of other acquaintances, listed in his cell phone (see Jake's Phone). Shelby, an earthworm and friend of Jake, lives in his viola.

Jake and the Squirrel are enemies, because Jake wouldn't publish the Squirrel's letter in his newspaper advice column, and now the Squirrel wants revenge.

In "My Two Favorite People," Jake befriends a boy named Tiffany in an attempt to get Finn and Lady Rainicorn jealous of him. However when Jake makes up with Lady, Finn fights Tiffany and spits on him, causing Tiffany to run away screaming. Before leaving, he vows that he will still become Jake's best friend, although he has not appeared in any other episode since.

After Susan Strong tried to eat the Candy Kingdom, Jake starts to think she is crazy as shown in "Beautopia." Jake constantly repeats that she is insane to Finn throughout the episode, and follows Susan and Finn to annoy and disrupt them.

When Jake had a Croak Dream with the Banana Man in it, he was scared of the Banana Man at first. As Jake grew to accept death, his dislike of the Banana Man lessened. Jake thinks that he and Banana Man are destined to meet again, when Finn isn't around.

In the episode "His Hero", Jake stated he had a secret crush on Billy. And whenever they meet, Jake keeps saying "I love you, Billy!"

In "Princess Cookie," Jake befriends Baby Snaps once he knows his story about keeping the hostages. Jake is also happy when Baby Snaps says he reminds him of a mailman he knew.

Jake's Subconscious
Jake's Subconscious is the subconscious manifestation of Jake that appears in the episode "The Witch's Garden." He is first seen at the River of Junk when Jake said that crossing the river looked hard. Jake's Subconscious then appears before Jake and also tells him that it is too hard to cross the river, and that Jake should simply wear a hat instead. This suggests that Jake's subconscious has a personality similar to Jake's. He later appears when Jake is making his appeal to the Witch in order to get his powers back. When Jake refuses to give in to the Witch's humiliating demands, Jake's Subconscious tells Jake that he is the subconscious form of Jake's old magical self, and is therefore beginning to die. This makes Jake start to cry and apologize. The Witch is thoroughly happy with Jake's sorrow and decides to take pity on him. She returns his powers and subsequently restores the vitality of his subconscious self. Jake and his subconscious then leave the Witch's garden in laughter after Jake takes away the Witch's cane, rendering her powerless.

Although Jake's Subconscious is translucent and merely Jake's subconscious, he is still solid as when Jake cried over his dying body, tears ran off to his sides. It can be assumed that only magical beings can see Jake's Subconscious because while Jake was having a vibrant conversation with his subconscious, Finn tells him to "stop talking to yourself!" (However, since Jake's subconscious is part of Jake, he was technically talking to himself, so Finn might have heard him). The Witch who stripped Jake of his magical powers was also somehow able to see him and hear him, because she stated: "He said he's dying."

Conductor
The Conductor is the main antagonist in "Mystery Train." Throughout the episode, he comes and goes during the train ride, and begins creeping Finn out. Not until all other suspects are dead is he actually suspected of murdering all the candy people, because according to Finn, "It's never the creepy guy who's the murderer". After supposedly "murdering" everybody, including Jake, Finn chases him across the entire length of the train. After a short one-on-one battle in the train's control room, he is revealed to be Jake in disguise-via pink and blue paint and his stretchy powers. The paint may be some sort of liquid candy, since Jake licked it off of himself after he revealed himself.

Magic Fist
Magic Fist is the disguise Finn and Jake wore in "Wizard Battle" in order to be eligible to compete. Click here for more information.

Gut Grinder
Even though Jake was not the Gut Grinder, he believed himself to be the Gut Grinder so much he became one. And throughout the episode the scared townspeople thought Jake was the Gut Grinder. The Gut Grinder was actually Sharon the mayor's wife. Soft People, Cube People, and Spikey People all thought that Jake was the Gut Grinder.

Groucho
When entering the Spikey Village in the episode "Gut Grinder;" Finn gave Jake a pair of "Groucho glasses" so that the Spikey People wouldn't think Jake was the Gut Grinder. Jake donned the combination glasses/ nose/ mustache and introduced himself as "Groucho," a clear homage to Groucho Marx.

Baron of the Grasslands
In Incendium, Jake claims to be the "Baron of the Grasslands", and an envoy of "Prince" Finn. Jake pretended that he was of royal blood to court Flame Princess for Finn but later on discovers that Flame Princess is evil.

Randy Butternubs
In the episode "The Creeps," Jake wears a tall top hat with a green mask along with a purple cape with a tuxedo and a bow tie. He also wears black shoes. Jake shows lack of appreciation for his given name when he throws the card on the ground. In the episode, Finn thinks he is behind the mystery of the haunted, old house but the whole time it is Jake. He has been planning that prank for months and days.

Lumpy Jake
{C In the episode "Trouble in Lumpy Space," Jake was turned lumpy during the Mallow Tea Ceremony when Lumpy Space Princess falls on him and bites him causing Jake to get The Lumps. When he turned back to normal Jake, he was at Promcoming and he fell on the antidote that Finn brought. He is pink and his face looks the same. He only has four lumps not including his tail, and talks like Lumpy Space Princess. He also developed an attitude similar to Lumpy Space Princess.

Demon Jake
Demon Jake appears in "Daddy's Little Monster" so they can sneak into the Nightosphere. He sings "Demon Apathy" in this form. Jake looks like a quadrupedal demon with big and sharp teeth.

Zombie Jake
Zombie Jake appears in" From Bad to Worse" when he was bitten by a Candy Zombie. Zombie Jake looks like Jake but with grey skin and cracks throughout his skin. Zombie Jake is the first zombie to be cured in "From Bad to Worse," but turns back into a zombie when the other zombies see that he is not a zombie and start biting him. A different version of Zombie Jake appears in the Adventure Time game, Rhythm Heroes.

Milk Man/Mail Man Jake
In the episode "Princess Cookie", Jake dresses as a milk man in order to rescue hostages. Finn dresses in an outfit similar to that of a ninja, pretending to be Jake's shadow. In the end of the episode, dressed as a mail man, he delivers a daisy crown to Baby-Snaps.
