Gohan's Rage

As Raditz tortures Goku, Gohan bursts out of Raditz's spaceship and hurls himself into Raditz with incredible power that stuns and injures the Saiyan. However, Gohan's power disappears as quickly as it surfaced, leaving him defenseless against his father's attacker who quickly hits Gohan, knocking him out. Raditz intends to kill Gohan, who he views as the only person capable of defeating him. In a last-ditch effort to save his son, Goku grabs Raditz in a hold that leaves both of them open to Piccolo's Special Beam Cannon. Goku urges Piccolo to use it, even if it costs his own life. Piccolo then starts to wonder whether or not he should use it. Despite Raditz's pleas for mercy, Piccolo lets loose his attack, which hits both Goku and Raditz, killing the latter. Thinking they've already won, Piccolo tells Raditz (who's slowly dying) about the Dragon Balls, and that they have the power to grant almost any wish. So Goku will not be dead for long. Once he's heard everything, Raditz tells Piccolo that his Scouter is also a transmitter and that in one year's time, two more Saiyans, more powerful than Raditz, will arrive on Earth to destroy everyone. Goku lives to see Bulma, Roshi and Krillin arrive and hear that the unconscious Gohan is alive, but thereafter dies, leaving his body to be taken by Kami. Far away on another planet, Nappa and the Saiyan Prince Vegeta, Raditz's superiors, having heard everything through Raditz's Scouter, plan to visit Earth and wish for immortality using the Dragon Balls.
