Proper Japanese Title: Katsute Nai Kyōfu (かつてない恐怖)
Son Goku is the greatest hero on Earth. Five years after defeating the demon king Piccolo, he's grown up and had a family--he's married, and he has a child, Son Gohan. But what is the real reason for Goku's incredible strength? A visitor from outer space arrives bearing terrible news--Goku is an alien, and the visitor, Raditz, is Goku's brother! When Raditz turns out to be a ruthless killer, Goku must fight his incredibly strong brother to save his family and the entire human race. A surprising alliance may be Earth's last hope: Goku will team up with his old enemy Piccolo...archenemies united to save the world!
Having dodged the attack by a hair's breath, Goku rams Piccolo with all his weight from high in the sky to win the tournament. Several years later, the Saiya-jin Raditz, who claimed to be Goku's older brother, appeared before Goku and his son Gohan. Raditz's astounding power was such that not even Goku and Piccolo could defeat him. Goku sacrificed his life to defeat Raditz. Raditz said that in one year, other powerful Saiyans would arrive.
