Piccolo dies from Nappa's ki blast, resulting in Kami's death and the destruction of Earth's Dragon Balls. However, Goku finally arrives at the battlefield just in time to save Gohan and Krillin. After healing the two with a Senzu bean from Korin, Goku engages Nappa in battle. Despite the mighty Nappa's efforts, it quickly becomes clear that he is no match for Goku's new level of power.
