Goku's group separates to find the androids, and Yamcha ends up being attacked by them. Goku and his friends save him, and the former transforms into a Super Saiyan to fight Android #19. Although Goku overpowers #19, he is suddenly weakened by a heart disease that Trunks warned he would have. Vegeta appears to save Goku, who is taken to his house by Yamcha. Vegeta transforms into a Super Saiyan and easily kills #19. Android #20, who is in fact the creator of the androids, Dr. Gero, escapes to his laboratory and is followed by the warriors. As Piccolo finds and overpowers Gero, Trunks appears, saying that he is not one of the two androids from the future. Gero escapes again and awakes the androids #17 and #18, who quickly turn against him.
