Bikini (ビキニ)[3][4][5] is the wife of Dr. Brief, the mother of Tights and Bulma, the mother-in-law of Vegeta, and the maternal grandmother of Trunks and Bulla.

Bikini went unnamed in the original manga, anime and guidebooks, only ever being referred to as Bulma's mother (ブルマのママ Buruma no mama).[1] In an interview, Toriyama noted that had he named her he probably would have gone with Panchy (パンチー Panchī),[6] which was later used as her name in Dragon Ball SD.


Bikini with her eyes open, a rare occurrence

Bikini has a thin frame and blonde hair. Her eyes are almost always closed yet, ironically, she is still able to see everything clearly when they are. She is shown to wear upscale clothing and jewelry. 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, Bikini appears to be all but untouched by time or age in all her appearances, dating from Bulma's late teens to present day Trunks' early adolescence. This agelessness seems to hold somewhat true for her husband as well.

In Dragon Ball Super, Bikini's hairstyle alters for the first time in the series. She wears a long purple dress and white pearl necklace in the first saga, then reverts to her orange-striped sleeveless shirt and blue jeans in the next two sagas. Her height, which seemed to be slightly shorter than Bulma's 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, Bikini has been shown to be a bit of a ditz despite her attractiveness and beauty. For example, she does not even know that Future Trunks is an older version of her grandson, Trunks, though it appears she learned in Super. However, in the Dragon Ball Z Kai version of the show, she is portrayed as slightly less ditzy in the dub, being more aware of situations 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 being lacking at best or downright terrible at worst, and is one of only two to do so (the other being an extremely drunk Master Roshi).[7]

Bulma's mom searches for Scratch

She seems to be, along with her husband, almost entirely oblivious to a serious situation. When King Piccolo was coming to destroy West City, they simply tried to get all their pets and leave. Later on, when they were offered a chance to stay on The Lookout while Majin Buu was at large, she and her husband declined just so they could feed and look after their pets; she reasoned: "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 indicates that throughout the series they care quite a lot for their pets. It is shown in the Gods of the Universe Saga that like her husband she was unaware that he was the richest man in the world until it was pointed out to both of them by Mr. Satan at Bulma's birthday party.

Usually friendly, Bikini does show signs of anger in some 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 makes a "mess" on her carpet.

Bikini has some sort of obsession with sweets, a fact not lost on her grandson who once remarked to her, "What is it with you and food?"

Bikini, Dr. Briefs, and a young Bulma visit her eldest daughter Tights on Omori's Island and meet her daughter's friends Jaco and Omori. During their stay on the island, Bikini is unphased when her five-year-old daughter Bulma fires a powerful Ray Gun she had invented into the ocean, instead politely asking the awestruck Omori (who was shocked by Bulma's little display) if he had another bottle of beer.

Vegeta and Bikini

Bikini'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. She is shown to be somewhat caring towards Vegeta after he is sent to Earth with everyone else who had been revived with the Namekian Dragon Balls.

Cell Saga

Main articles: Androids Saga, Imperfect Cell Saga, Perfect Cell Saga, and Cell Games Saga Her caring role continues through the period of Vegeta training to become a Super Saiyan in order to fight the Red Ribbon Androids. She remarks to the Saiyan prince that he is a worthy suitor for her daughter because of his perseverance. In addition, when first meeting Future Trunks, she remarks it was a coincidence that he shares the same name as her newborn grandson, apparently not being aware that he's in fact a future version of him.

Majin Buu Saga

Bikini talking about Vegeta with Bulma

Later, 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 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 that in case they are killed, they can be wished back to life. Goku confronts both Buu and Babidi to prevent them from going there while she and her husband assist Trunks in finding the radar. Bikini tries to get Trunks to take a break and eat throughout the search, but he constantly refuses, explaining the urgency of the situation. Though, neither 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, but are later revived with the Namekian Dragon Balls.

Bikini in Buu's Fury

Bikini appears briefly during Future Trunks' ending in Dragon Ball Z 2: Super Battle. She makes a cameo in the end credits of Dragon Ball Z: The Legacy of Goku. In Dragon Ball Z: The Legacy of Goku II, she gives cookies which restore the health of the Dragon Team 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.

Bikini also appears in Dragon Ball: Origins 2 and Dragon Ball Z: Attack of the Saiyans. In Attack of the Saiyans, her hair is green.

She makes an appearance in the electronic trading card game IC Carddass Dragon Ball as a playable character.

In Dragon Ball Z: Kakarot, she is mentioned by Dr. Brief who refers to her by her official name Bikini. She is also referred to as Bikini in her husband's Z Encyclopedia entry.

Voice Actors


  • Like the rest of her family, Bikini's name is a play on some type of undergarments; in this case "Bikini". Her alternative name Panchy is a pun on "panty" or "panties."
  • In the Latin American Spanish 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 Spaniard Spanish 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.
    • Despite not looking it, she is about the same age of her husband, and it's said by Akira Toriyama that, by the time of the film Dragon Ball Z: Battle of Gods, Bikini and her husband are at least 70 years old.[8]
  • Bikini and her eldest daughter Tights are the only members of the Brief family with blonde hair. Presumably, Tights inherited her blonde hair from her mother (in the manga, Bulma inherits the blue/purple hair color of their father, which Bulma later passes on to her son Trunks in both the manga and anime, as Trunks has the same hair color as Dr. Briefs in the anime)
  • Bikini looks and acts real similar to Murasaki Kimidori from Dr. Slump.
