Alice is one of the survivors of the Saiyan clan. She escaped because her character was too violent, and King Vegeta realized that she wanted to overthrow his rule, so he expelled her from Planet Vegeta.
Frieza found her three years after the destruction of Planet Vegeta and personally recruited her under his command.

For this reason, Frieza also personally gave Alice some humane care, the kind of physical kind that made her lie on the floor for a few days.
