The character made his debut in the original pilot. Jake is Finn's best friend and adoptive brother. He is a shape-shifting dog who is in his 30s in "magical dog years".[1] 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.[2]

Jake has a laid-back attitude in most situations, but loves adventure and is in a relationship with Lady Rainicorn voiced by Niki Yang; they have five children together.

The character has received largely positive critical reception.
