Jake (Full Title: Jake the Dog), is a main character in the series Adventure Time. He is Finn's best friend, roomate, loyal companion and adoptive brother. He has stretchy powers and can stretch into anything. Both he and his girlfriend, Lady Rainicorn , share a passion for playing the viola. Jake had magical powers when he was a puppy.


He is a orange/yellow English Bulldog with large, characteristic eyes.

He wears invisible spider pants seen "Donny". He sometimes wears costumes and pants.  In the episode "Chamber of Frozen Blades", he wears a pink glove but he already taked it off.


He has stretchy powers and can morph into different shapes. He can 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 of Me-Mow's poison. One frequent use of his powers is Key Hand, which he uses to pick locks. He has also used his arm as a bow able to accurately shoot arrows at a short distance. 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. In "You Made Me!," he is shown to be able to move objects through his body freely when he lets Princess Bubblegum jump into his mouth and then pushes her up through his back. 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" he can stretch body but it has limit, if he stretch to much he will get thin and might die, also he cannot blink eyes. He can go into different heights.

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. In "The Chamber of Frozen[1]Blades" he stated that his sense of smell is "like 1,000 times better" than Finn's, although compared to normal dogs this is a somewhat low estimate, suggesting that he was either just guessing, or his sense of smell is not magic and just that of an average dog, albeit one with human intelligence. 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 defeats him effortlessly. This demonstrates that Jake is not proficient in swordplay, at least relative to Finn. During the same time, 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 Dream." Anything he imagines becomes reality; however, only he can see his own creations.

Jake is a skilled musician as well, particularly with the viola, which can have peculiar effects when playing certain pieces such as the first movement of Beethoven's 14th piano sonata. Jake's viola is the home of Shelby the Worm and has the word "toots" scratched on the back, which is shown in the episode "What Was Missing." In the same episode, Jakes purposefully breaks his viola and, later, repairs it. Jake also plays the acoustic guitar, as seen when he plays the titular song in "Susan Strong." It is shown in "Incendium" that he can also play ukulele. Jake will beat-box on occasion,  Finn describes Jake as "the musical one."

Jake sings often in the series, usually along with Finn or on his own. Some of his songs are Bacon Pancakes from "Burning Low," On a Tropical Island from "Morituri Te[2]Salumatimus," and I'm On a Boat from "Beautopia."

He knows many things about dreams seen in the episode "King Worm".
