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 twenty-eight in magical dog years, but he rarely acts maturely. Both he and his wife, Lady Rainicorn, share a passion for playing the viola. Jake and Lady now have five mixed species pups, Charlie, Jake Jr., T.V., Viola, and Kim Kil Whan.
