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 the original Japanese version, Mrs. Brief has been shown to be ditzy. For example, she does not even know that Future Trunks is the older version of her grandson, Trunks. However, in Dragon Ball Kai, she is portrayed slightly less ditzy in the English version, 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. This makes Son Gohan comment that she is weird after dropping Bulma off during the Androids Saga. In addition, presumably because of her ditzy nature, she complimented Kuririn'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 anime 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??"
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' childhood. This also seems to hold somewhat true for her husband.
Dragon Ball (Anime)
When Goku comes to her house to see If Dr. Brief is done with his remodel Saiyan Spaceships. She tells Goku not yet and takes him to It. She then tells Goku that she be right back to get a drink. Then when she comes back with the drinks, she, Oolong and Puar witness Goku starting up his ship to go to Planet Namek.
later, she meets Vegeta after he is sent to Earth with everyone else who had been revived with the Namekian Dragon Balls. 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 arc
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 (Anime)
Battle of Gods arc
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 arc
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 arc
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.
Dragon Ball GT (Anime)
Mrs. Brief is not seen at the end of Dragon Ball Z, nor she is seen at all in Dragon Ball GT, suggesting she may have passed along with her husband sometime before GT begins. At this point, she would be over seventy, since Bulma is over fifty years old during this time. Future Trunks' life in his timeline shows that she has passed sometime during his teen-hood, as neither he or Future Bulma express any anger that she was destroyed by the Androids, only leaving natural cause.
