Jake

"I'd rather be dancing with some babes!"- Jake

Jake (full title: Jake the Dog), the deuteragonist of Adventure Time, is a magical dog and Finn's constant companion, best friend, and brother by adoption. 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. Both he and his girlfriend, Lady Rainicorn, share a passion for playing the viola. Jake and Lady someday hope to have mixed species kids.

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

He can morph into all sorts of fantastic shapes, thanks to his Stretchy Powers.He also wears invisible pants made of spider webs spun by pixies. When he was a puppy he was small enough that his father, Joshua, could loom over him. His insides smell like vanilla, thanks to a wizard.

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. 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 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. 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,or it is shown that he can control organisms.

Jake is also a skilled musician, 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 Nachtmuzika" by Mozart. 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. Its also in shown in Incendium that he can play ukulele.

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 (they never use their powers again after the epsiode 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 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 a helpful, fresh perspective 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 also be dyslexic due to the fact that he writes backwards, as shown on his note to Finn in "Storytelling."

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: "Jake, you don't really focus at all." It could be possible that he has A.D.D.

Jake also is very musical. The biggest factor is how he plays the viola a lot. He has sung a couple times, the most notable time being shortly after the House Hunting Song, when he sings to Finn a song about home being "where your heart is." It is shown that he can be seen playing guitar the episode "Susan Strong." and ukulele as seen in "Incendium" (Yes, it is a ukulele due to its sound.) In the episode "Death in Bloom," Finn even says that Jake is the "musical one" out of the two of them.

At times, Jake can be a bit dark when compared to Finn. Throughout the series, Jake makes some questionable comments and actions that may 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."

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 is fully aware of Finn's crush on Princess Bubblegum and even helps him try to win her over. 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 other's 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 treasure's 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 sometimes calls Finn homie.

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 always naked.

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. 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 have to children with Lady Rainicorn[[File:캡처.png|thumb|294px|Fun Fact: Jake's letter to Lady Rainicorn's parents: "To Mrs. and Mr. Rainicorn, 47 Rainbow St.

Please come exactly 1 hours 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, as evidenced by the fact that 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 says his fear was based on "ignorance." 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 they seem to have a rather friendly relationship (i.e Jake resting his head on her lap and complimenting her, PB petting him and calling him puppy in a sweet, baby voice.)

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.

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 brother named Jermaine.

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 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.

Jake's Subconscious
Jake's Subconscious is a version of Jake in the episode "The Witch's Garden." He is translucent, and appears to be somewhat of a conscience. When he is first seen, he tells Jake that he is right to think that crossing the River of Junk is hard work, telling him instead, to wear a girly hat. He appears later in the episode dancing with the real Jake with flowers in his underwear in order to get the Witch to accept his apology. He dies because he is the former version of Jake with his magic powers (Jake had his powers taken away by the witch earlier in the episode). He is brought back to life after Jake apologizes to the Witch and gets his powers back. The only two people that can see him are the Witch and Jake, as Finn told Jake to stop talking to himself. Though, Finn could have seen him, and told Jake to literally stop talking to himself.

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 through out 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.
