King Furry (King Koku in Japanese) is a dog who is the current king of the Earth. He is one of the few people who knows that Goku is a hero. Though he is a politically important in the Dragon Ball universe, he is of little significance to the storyline, save when King Piccolo temporarily usurps his throne. He was going to commemorate Goku with a medal for his heroic battle against King Piccolo, however Goku left for Kami's Lookout. From Dragon Ball Wiki, a Wikia wiki.
