Mrs. Briefs is Bulma's mother and the wife of Dr. Briefs. She is always interested in flirting with Goku and Vegeta. In the anime, she comments that she would like to go on a date with Vegeta and Goku. When Vegeta was offered a place to stay by Bulma - not long after Vegeta had tried to kill the Z Fighters - he was immediately welcomed in and taken aback by Mrs. Briefs; the shock of someone being so pleasant to him almost overwhelmed him.
Not much is known about her, but in the anime she's characterized as the archetypal blonde airhead who loves shopping and eating expensive cakes. Probably the most special feature of this woman is the fact that, as far as physical appearances go, she looks at least as young as her daughter, and unlike Bulma, she doesn't appear to age at all throughout Dragon Ball Z.
Not much is known about her, but in the anime she's perpetually happy, and is characterized as the archetypal blonde airhead who loves shopping and eating expensive cakes. Her first name is unknown.
