Summary
- Goku's presence on Earth has caused many of the most powerful villains to come looking for him.
- Goku's genetics as a Saiyan made him a target for extinction-level threats like Raditz and Vegeta, while his history of defeating villains directly resulted in the creation of the Androids and Cell.
- However, even when Goku tried to stay dead, villains continued to appear, so the citizens of Earth are actually better off with him around than they are without him.
