Burdock

Burdock was the husband of Gi-ne and the father of Raditz and Kakarrot. Working for Freeza's army, Burdock helped clear planets of their inhabitants for living space for other races. After being ordered by Freeza to return to Planet Vegeta under mysterious circumstances, Burdock became suspicious of his intentions.

As a result Burdock decided to send his youngest son, Kakarrot to another planet, Earth, for his own safety. A short while later, Burdock's hunch proved correct and Freeza attacked planet Vegeta.

Burdock made a last stand but was ultimately killed by Freeza along with the vast majority of the Saiyan race and planet Vegeta itself.
