An ancient and wise martial arts master and the first Earthling to wield the Kamehameha. Though he seems frail, he is a mighty warrior, having trained Grandpa Gohan, Ox King, Son Goku, and others. He is a stock character, as he is both the archetypal wise old man and dirty old man, the latter being typical of shonen manga. Still, he is depicted to be a very wise and gentle person, who loves life and its simple pleasures, but is willing to die if necessary.He sometimes gets cranky, which further provides comic relief. He is bald, with a thick van dyke beard and wears sunglasses. He usually wields a walking stick. When wishing to act anonymously in the World Martial Arts Tournament, Roshi uses the name Jackie Chun.
