| | Doctor Gero - Wikipedia, the free encyclopedia |
 | | After an explanation of their origins to Goku, Tien and Krillin, Android 20 single-handedly destroys half of the city. |
 | | During the fight with Vegeta and the others where he is betrayed by Dr. Myuu who commanded Super Android 17 to kill him leading to his somewhat ironic death (Killed by Android 17 again), which saddened Gero greatly, since his creation once again betrayed him. |
 | | Androids 17 and Android 18, like Gero, are not completely machine, rather being partially organic to some extent(as shown when 18 described it and the fact that 18 conceived a child), and therefore are human. |
