Bulma's Mother

Bulma's unnamed mother is 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 Bulma's mother; the shock of someone being so pleasant to him almost overwhelmed him.

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. She appears to never age throughout the series and still looks just as young as when she was introduced towards the start of Dragon Ball.

Her real name is unknown but Akira Toriyama has stated that if he were to give her a name it would have been "Panchi" (pun on "panties").
