"No, he wasn't. Frieza was something else. I never bothered to learn what species or race." Trunks confirmed, committing the names she gave him to memory. Just in case. "So, Saiyans. Goku was a Saiyan. No one knew this though, because he'd been sent to Earth as a baby to wipe it out, and hit his head and had amnesia." Which said something about the view of Earth, if they felt a baby could wipe out its population easily enough.

"Mom and the others, including Goku himself, didn't know he was this until about when Goku was married, with a kid. Because then his brother showed up to find out what had happened, and oh hey, decimate the planet if he could." Quick version--because this could get long. As Sunset had already found out. "I'll tell you the longer version of this some other time. So, Goku is an saiyan. His son, Gohan, is half-saiyan. By this time, there only 3 beings known to have Saiyan blood, all residing on Earth. Goku, his son, and then Prince Vegeta."
