Episode 60, "Attacked on Both Sides by an Internal Enemy?! Son Goku vs Artificial Human No. 19"
*****SPOILERS*****
Synopsis: Yamucha reveals that the Artificial Humans are capable of draining energy. He flies off with Kuririn and Gohan to warn Goku and the others about it and bring senzu beans to them. Goku and the others land in a deserted area. Tenshinhan notices that Goku’s already out of breath for some reason. One of the Artificial Humans, no. 20, reveals that Dr. Gero had a small robot investigate Goku during many of his major battles in order to gauge his power. However, they didn’t think it was necessary to follow them to Namek, which Goku and his group see as a big slip-up, as they have no idea that Goku is a Super Saiyan. Goku transforms into a Super Saiyan and Artificial Human 19 engages him in battle. The two exchange blows. Gohan and the others arrive, and Gohan and Piccolo notice how Goku is rushing the battle and seems weaker than expected. Goku fires a Kamehameha, which the android absorbs. No. 19 gains ground in the fight. Gohan reveals that Goku’s heart virus is acting up, as he never took the medicine, since it never manifested before now. Even a senzu bean doesn’t help Goku, and 19 pins Goku down, absorbing his energy.
