Mrs. Brief has a thin frame and blonde hair. Her eyes are almost always closed yet she is still able to see everything clearly when they are. Mrs Brief also is seen to wear upscale clothing and jewellery. In her first appearance she wears a blue dress. Later on in the Namek Saga, she wears an orange shoulder-less shirt and tight blue jeans. Despite no mention of extraordinary life extension, Mrs. Brief appears to be all but untouched by time or age in all her appearances, dating from Bulma's late teens to modern-day Trunks' early teen-hood. This also seems to hold somewhat true for her husband.
In Dragon Ball Super, Mrs. Brief's hair look alters for the first time in the series. She wears a long purple dress and white pearl necklace in the first saga, then reverts back to her orange striped sleeveless shirt and blue jeans in the next two sagas. Her height, which seemed to be slightly shorter than Bulma in the earlier series has now elevated to being the tallest female, as she is shown taller than Bulma, Chi-Chi, and 18 when talking with them at Bulma's party.
In the original, Mrs. Brief has been shown to be ditzy. For example, she does not even know that Future Trunks is an older version of her grandson, Trunks. However, in the Dragon Ball Kai version of the show, she is portrayed slightly less ditzy in the dub, being more aware of the situation and commenting from time to time based on the circumstances rather than having no clue of what's going on (yet, Gohan still comments that she is weird after dropping Bulma off during the Androids Saga). In addition, presumably because of her ditzy nature, she complimented Krillin's singing ability during a Karaoke session at a Hanabi picnic, despite his singing ability being lacking at best, and downright terrible at worst.
She seems to be, along with her husband, almost entirely oblivious to a serious situation; such as when King Piccolo was coming to destroy West City, they simply tried to get all their pets and leave. Another example is when they were offered a chance to stay on Kami's Lookout while Majin Buu was at large, and she and her husband simply declined just so they could feed and look after their pets; she said: "Remember even if we meet a gruesome, gory and grotesque end at the hands of this Majin Buu, you can always bring us back with the Dragon Balls." This would prove that throughout the series they care quite a lot for their pets.
Despite being mostly friendly, Mrs. Brief does show signs of anger in fillers. For example, she gets angry when Dr. Brief tells Chi-Chi that the ship is ready for Namek right after her father persuades her not to go. Also, in the video game Dragon Ball Z: The Legacy of Goku II, if the player goes over the cookie limit, she informs him that she will get upset if he make a "mess" on her carpet.
Mrs. Brief has some sort of obsession with sweets. When Trunks was a kid, he even stated "What's with you and food??"
Dragon Ball Z
Mrs. Brief's primary role in the series is to take on a housewife-esque role at Capsule Corporation, and her detailed roles are primarily filler. In "Clash of the Super Powers", she mentions that she used to have a poodle but it got lost. Her role is put into detail in the anime as being somewhat caring towards Vegeta after he is sent to Earth with everyone else who had been revived with the Namekian Dragon Balls.
Main article: Androids Saga Her caring role continues through the period of Vegeta training to become a Super Saiyan and fight the Red Ribbon Androids, in which she comments on him being a husband-worthy man for Bulma because he is seen to be hard-working.
Majin Buu Saga
Main article: Majin Buu Saga
Later, during the Majin Buu Saga, she and her husband choose to stay at Capsule Corporation rather than go to Kami's Lookout where it is safer. This worries Bulma, and eventually leads to West City being targeted by Majin Buu after their Trunks' address is revealed to Buu and Babidi. Trunks also shows great concern for both his grandparents during this time, heading to Capsule Corporation to get the Dragon Radar so in case they are killed, they can be wished back to life. Goku convinces both Buu and Babidi to avoid going there while she and her husband assist Trunks in finding the radar. Mrs. Brief tries to get Trunks to take a break and eat throughout the search, but he constantly refuses and explain the urgency of the situation, though, she nor her husband seem concerned. After finding the radar, Trunks leaves after commenting on his grandmother's strange fascination with food. Later, she and her husband are killed off screen during Super Buu's Human Extinction Attack.
Dragon Ball Super
Battle of Gods Saga
Main article: Battle of Gods Saga Mrs. Brief attends Bulma's birthday party with Dr. Brief. She is shown mainly with her husband, first seen sitting with Ox-King. She is later seen with the other women. Interestingly, she is frequently shown with her eyes open throughout the saga. When Beerus shows up, Mrs. Brief and her husband witness the Z-Fighters battle against him, and seems concerned when they lose. She also displays horror when Beerus gets ready to destroy the Earth in episode 8, but relieved when he gives them a chance to live after challenging Oolong to a game.
Resurrection ‘F’ Saga
Main article: Resurrection ‘F’ Saga Ten months after the encounter with Beerus, Frieza is revived and seeks revenge on Goku. While fighting Vegeta, Frieza blows up the Earth. Bulma's mother is having lunch with her husband Dr. Brief at Capsule Corporation when she witnesses Frieza's explosion, leading to her death. This event is however reversed by Whis doing his Temporal Do-Over technique. After this, Bulma prepares a feast for her family and friends so Bulma's mother attends.
Universe 6 Saga
Main article: Universe 6 Saga Bulma's mother is featured as a background character as she and her husband travel with the others to support Beerus's team in the tournament.
Video game appearances
Mrs. Brief appears briefly during Future Trunks' ending in the arcade game Dragon Ball Z 2: Super Battle. She makes a cameo in the end credits of Dragon Ball Z: The Legacy of Goku. In the Dragon Ball Z: The Legacy of Goku II, she gives cookies which restore the health of the Z Fighters for free. In Dragon Ball Z: Buu's Fury, she will clean dirty clothing to increase the stat bonus given by the equipment. Bulma's mother is a support character who gives different types of potion to the Z Fighters in Dragon Ball Z: Harukanaru Densetsu.
- Japanese: Mariko Mukai (Dragon Ball, Dragon Ball Z Seasons 1-4), Hiroko Emori (Dragon Ball Z Season 5, Movie 8) and Yoko Kawanami (Dragon Ball Z Seasons 6-9, Dragon Ball Kai)
- FUNimation dub: Cynthia Cranz
- Ocean Group dub: Jane Perry
- Blue Water dub: Jennifer Bain
- AB Groupe dub: Jodi Forrest
- Brazilian Portuguese dub: Cecília Lemes
- In the Japanese dub of the show she is apparently unaware of Chi-Chi's name, simply referring to her as "Goku's wife" and "Missus".
- In the Spanish (Latin America) version, when she first appears, she is referred to as Bulma's sister, probably because Bulma is shown yelling at her a lot, which could be taken as a bad example for kids. However, the Spanish (Spain) version introduces her properly.
- During the entire Dragon Ball franchise, she does not seem to look older, however it is apparent she is well over middle-aged by the Buu Saga, as Bulma is over forty at the time.
- She does not make any appearances in the Dragon Ball Z: The History of Trunks special or in Dragon Ball GT, and it is revealed that her husband had died sometime before Age 780.
- In the beginning of the series, Mrs. Brief seems to have an inconsistent height. In Dragon Ball, she is shown to be around the same height as Bulma during her first introduction. In Dragon Ball Z, she is seen slightly shorter than Bulma in a few scenes, and shorter than Vegeta in the Cell saga. However, in her first meeting with Vegeta in the Frieza saga, she is taller than him. She is also seen taller than Bulma in a photograph during the Buu Saga. Dragon Ball Super appears to officially establish her as taller than Bulma, as well as the other female characters at the party in episode 6, thus, making her the tallest female character in the current timeline. Her towering height remains consistent throughout the rest of the saga.
- Despite the inconsistency in Dragon Ball Z, various fan art have depicted the character as taller than Bulma before Dragonball Super officially started doing the same.
