Gine

Gine was the Queen of Planet Vegeta and wife of Bardock, mother of Son Goku, and adoptive mother of Vegeta. She attempted to keep the peace between the family even when Vegeta discovered he was the true son of another Saiyan lineage and became vengeful towards her and her husband. When Goku brought Bulma Briefs to Planet Vegeta to protect her from the powers of the Dragon Balls, Gine took care of her and defended her against the attacking Majins, even sacrificing her life at the hands of Majin Buu to ensure her safety. Gine's death allowed Vegeta, whom she had always cared for, to reconsider his life choices and join with his brother to avenge her death, although her death was not enough to change Vegeta's desire to rule.
