Despite his newly-found confidence, Goku realizes he has no chance against Frieza, who is still using only 50% of his power. At this point, Goku decides it is time to use his ultimate technique: the Spirit Bomb. With very little objects left on Namek to borrow power from, he decides to borrow from neighboring worlds. Angry because he cannot figure out what Goku is doing, Frieza pummels Goku, who cannot get enough time to create the Spirit Bomb. Taking what little energy Gohan and Krillin have left, Piccolo intervenes to buy Goku more time, but he is also pummeled. Frieza prepares to kill Piccolo as Goku finishes the Spirit Bomb.
