Mrs. Briefs, also known as Panchy, is the wife of Dr. Briefs, the mother of Bulma, and the grandmother of Trunks. She is a housewife with a warm, friendly and welcoming personality, always offering tea to visitors.
In episode 14 she tells Goku she goes by the nickname "MILF"
After the birth of her grandson, she began going by "GILF"
She lives by the code: Wives are for kissing, not talking.
She remains mostly in the kitchen.
She never ages because Dr. Briefs won't let her, because he has(or used to have) clones of her in the basement lab. This may also be a nod to the fact that she never does appear to age in the original anime.
She was against the idea of her husband planting explosive devices in her children.
