Dr. Brief, Bulma and Mrs. Brief

The Brief family consists of eight known members, plus four confirmed extended members and an unspecified number of unnamed ones. This is one of the two families in the series to have Human and Saiyan bloodlines (the other being the Son family).



Vegeta, Trunks, and Bulma

The Brief family is introduced in the series with the character Bulma, whose name comes from the Japanese pronunciation of "Bloomers" (a relatively old fashioned type of underwear). As with Akira Toriyama's naming puns, all the names of associated characters are related to one another. The Brief family's naming theme is being named after types of undergarments.

The Briefs are noted as a family from West City in the series. Supporting the fact that the Briefs are a western family, the Brief's last name is placed after the individual's name, which is consistent with family names in Western culture in real life. Furthermore, the Brief family is seen to primarily dress in western styled clothing.

Bulma's family has had a laissez-faire attitude for generations, but Bulma has complete control over things as a rule.[1]

Due to Prince Vegeta's entry in the family through his relationship with Bulma and their two children Trunks and Bulla, the Brief Family is related to the Saiyan Royal Family, which includes Vegeta's father King Vegeta and his younger brother Tarble.

  • In Dragon Ball: The Path to Power, when Goku meets Bulma, he laughs and says she has a funny name, to which she replies "Don't you think I know that? It's a family name" which is a reference to her family naming scheme.
