In the ensuing battle, Frieza and Goku trade blows, but as the fight progresses, Frieza's power gradually diminishes with the repeated punishment. In frustration, Frieza sends a Death Ball into the core of the planet, starting a chain reaction that would destroy Namek in "five minutes". Frieza unleashes 100% of his power. Frieza is now able to launch a huge assault against the surprised Goku, who had not expected Frieza's power to be as high as it is. Goku and Frieza face off and eventually after a very long battle, Goku gets the battle under his control, and calls off the fight, claiming it would be pointless to continue; Frieza losing strength rapidly and Goku already having humbled the tyrant. Humiliated, Frieza refuses to relent, attacking Goku with two Tsuibi Kienzan. As Goku dodges the attacks, Frieza ironically becomes distracted long enough to be vivisected by his own attack.
