Goku and Frieza begin their battle, and the tyrant has more trouble against Goku than he originally thought. The fighters exchange blow for blow, and discover that their powers are nearly equal while Piccolo, Gohan, and Krillin watch from the sidelines, amazed. Goku discovers that Frieza cannot detect someone's energy without a scouter, which our hero takes advantage of. However, Frieza traps Goku in an exploding energy ball, which nearly kills him. However, Goku manages to escape with only ripped clothing, and Piccolo states that neither of them are fighting at full power, yet.
