"Two-thousand years ago, the Earth was nearly destroyed. Not by man, but by gods from the sky. Their names were Piccolo and Oozaru."
Roshi (武天老師 Muten Rōshi, lit. "Old Heavenly Martial Arts Master") is a character in the 2009 film Dragonball Evolution. He is an adaptation of Master Roshi, the inventor of the Kamehameha technique in Akira Toriyama's Dragon Ball franchise, and is portrayed by Chow Yun-Fat.
Roshi is the former student of Sifu Norris (resembling Master Mutaito), the martial artist responsible for sealing Lord Piccolo away for centuries.
