The situation looks bleak for Goku and Piccolo, as Raditz easily deflects every attack they send his way. But Piccolo may have a way to stop the sinister Saiyan. He's perfected a powerful new attack, the Special Beam Cannon!There's only one problem: Piccolo needs time to gather the energy for the blast, which means Goku will have to last for five minutes against Raditz alone!
