A powerful fighter
Master Roshi is the martial arts master of young Goku in the Dragon Ball Z series. He trained the famous hero who will become himself one of the most powerful fighters, but also many other fighters, his reputation preceding him in the world of martial arts. Master Roshi lives in a cave like a hermit, having very little contact with the outside world but he is also a notorious pervert. He is often seen spying on young girls behind their windows or looking under their skirts. Goku will entrust him years later with the training of the son he had with Chichi, Gohan.
