Jake the Dog

Jake the Dog Sr. is a fictional character and one of the two protagonists of the American animated television series Adventure Time and its franchise created by Pendleton Ward. He also appeared in the spin-off series Adventure Time: Distant Lands. The character made his debut in the original pilot. During the events of the show, Jake says that he is 28 "magical dog years" old. Jake can stretch, shrink, or mold any part of his body to any shape and almost any size, ranging from becoming gigantic to becoming incredibly small. He acts as a confident mentor to his energetic adopted brother Finn the Human, though he tends to give somewhat questionable advice. His powers help Finn considerably in combat and transportation but are sometimes used as nothing more than pleasant forms of expression. He has a girlfriend named "Lady Rainicorn" (voiced by Niki Yang); they have five children together, as seen in "Jake the Dad". He is quite skilled at playing the viola, which houses a worm named "Shelby Butterson the Worm Who Lives in Jake's Viola". Jake has received generally positive reviews from critics. A gender-swapped version of Jake called Cake the Cat appeared in the third-season episode "Fionna and Cake", and is a main character of the spinoff series Adventure Time: Fionna and Cake.
