The battle on King Kai's planet begins with the Z-Fighters against the Ginyu Force and it seems that our heroes' training is paying off. Piccolo does his best for Goku to complete the Genki Dama, but it seems that Frieza might win this battle. At the last moment, the Genki Dama is completed, and Goku hurls it at Frieza, who can't control the force of the blast. Frieza is seemingly destroyed.
