Piccolo's Plan

Goku and Piccolo throw everything they've got against Raditz, but it seems that even with the weights removed, it seems their combined power stops short of Raditz's own strength. Both get injured and Piccolo even loses an arm. However, Piccolo has an idea that might beat him: the Makankosappo (Named "Special Beam Cannon" in the first english dub), his newest and most powerful technique that he was planning on using against Goku. But, he has to power up to make it work, and he requires five minutes to gather the strength, so Goku does his best to give him that. Despite the fact that the two drastically raise their power levels with heavy concentration, they do not manage to defeat Raditz using their attacks. Suddenly, Goku does manage to grab Raditz's tail, remembering that whenever someone grabbed his own tail, it effectively paralysed him. Raditz, now suffering from the same debilitating state, feigns surrender and Goku releases his tail, despite Piccolo's warning. However, Raditz quickly attacks Goku again elbowing him in the face and crushing his chest. As Raditz prepares to kill Goku, he suddenly picks up an enormous power level: it's Gohan who jumps out of the spaceship.
