"3 years later, yes. But not from Frieza or his family. Two Artificial Humans, known as Androids 17 and 18, appeared. They were regular humans who'd been so heavily modified as to no longer be considered 'human'--and they were angry. Psychotic and homicidal, they killed their creator. Then they went on to the rest of the Earth, doing what they pleased. No one left could stand up to them, and all the warriors who tried, including my Father, died. My mother isn't a fighter, per se, so she survived. I was 6 months old. Gohan, Goku's son, also survived."
