Master Roshi also known as the Turtle Hermit, is an ancient and wise martial arts master and the first character to wield the trademark Kmaehameha. Though he seems frail, he is a mighty warrior. Master Roshi trained Grampa Gohan, Ox- king, Goku, Krillin, and Yamcha. His home, named kame house, is a shack on a small isolated island, and serves as a gathering place for "his friends". He is both the archetypal wise old man and a perverted old man, the latter being typical of shōnen manga. Sometimes, he gets cranky, which further provides comic relief. He is bald, with a thick fu manchu, and a thick beard. Master Roshi wears beach clothes or a martial arts suit and a turtle shell on his back. He usually wields a walking stick. His companions are usually Oolong, turtle, and Launch.
