Name: Jake The Dog
Gender: Male
Age: 28 (in magical dog years)
Species: Dog
Jake (full title: Jake the Dog), the deuteragonist 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.
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." In "What was Missing" he borrows the pair of pants that Marceline wore in "It Came from the Nightosphere." When he was a puppy, he was small enough for his father, Joshua, to 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.
