While Mercenary Tao tires himself climbing the tower, Goku enjoys his moments with Upa who is amazed at Goku's confidence. Meanwhile Bulma's dragon radar is malfunctioning due to some radar jamming situation which is also affecting Commander Red. Tao... (more) reaches the tower summit and meets Korin. Arrogant Tao drinks the sacred water and Korin tricks him into thinking his strength is boosted. In addition Korin gives Tao a dark cloud to ride. Korin then causes Tao to plummet to the ground. Tao beats Goku, but Goku was just taking blows to read his moves. Tao acts a surrender and throws a napalm grenade at Goku, but Goku kicks it back. The bomb explodes right in Tao's front killing him. Meanwhile Bulma has finishing engineering her radar against the radar jammer which also boosts Goku's. Goku is off to defeat the RR at their HQ.
