The Brief family, also known as the House of Vegeta,[1] 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 Earthling and Saiyan bloodlines (the other being the Son family).

The family only possess the last name "Brief" in the English dub, in the original manga and Japanese version "Brief" is simply Bulma's father's name.



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.[2]

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.

Family History

Vegeta III and Vegeta IV

A comparison of Adult Vegeta IV and his late father Vegeta III in Broly

The Brief family originates from Bulma's side of the family. Vegeta was born into the Saiyan Royal Family on Planet Vegeta in Age 732 as the eldest son of King Vegeta and his queen. A few years after the birth of their first son, the royal couple had a second son named Tarble, who was deemed weak at birth and sent to a distant planet shortly after birth. At five years old, Vegeta was taken from his father by the galactic tyrant Frieza due to his immense strength that was considered abnormal for a child. After the destruction of his planet and the Saiyan race by Frieza, Vegeta was raised as a soldier in Frieza's army and was ordered to conquer planets at Frieza's order while secretly plotting to overthrow and kill Frieza for revenge for the abuse Frieza bestowed on him and his race. In Dragon Ball Super: Broly and Dragon Ball Minus, Vegeta survived the Genocide of the Saiyans due to ignoring Frieza's order for all Saiyans to return to Planet Vegeta, resulting in Vegeta, Raditz, Nappa, and two unnamed adult Saiyans working with them to survive and Frieza decided not to exterminate them, instead they were given a cover story that their home planet was destroyed by meteor impact. Vegeta revealed to Nappa that he was unsure if his younger brother was still alive or where he would have been sent to apparently unaware of Tarble's exile to Tech-Tech.

The Brief family is known as the richest family in the world when Dr. Brief invents capsules in Age 712, which turns earns him international fame and wealth. Bulma was born in Age 733 as the second daughter and youngest child of Dr. Brief and his wife, who had another daughter, Tights who is eleven years older than Bulma. A couple of years after Bulma was born, Tights left the family to pursue a career as an adventurer which inspired her to become an author, which left her estranged from her family. During her adventures, Tights befriends a Galactic Patrolman named Jaco who had been sent to save the Earth from the Saiyan child, Kakarot whom he believed was sent to invade unaware the boy was sent to Earth by his parents unauthorized to save him from Frieza's Genocide of the Saiyans. However Jaco missed the Saiyan child's arrival due to Tights pushing him off a cliff in a rage after being hit in the face by some urine produced by his Elite Barrage ability (which is how his species urinates). As a result, Jaco missed Kakarot's arrival leading to him being adopted by Grandpa Gohan who named the boy, Son Goku. In addition to Jaco, Tights befriends theoretical physicist Tokunoshin Omori and says on his island. Tights parents and little sister Bulma visit the island and are introduced to both Jaco and Omori, with Bulma demonstrating her scientific genius by fixing Jaco's Spaceship and showing off a powerful Ray Gun she developed that was strong enough to impress Jaco to the point he even asked her if she'd like to join the Galactic Patrol when she is older. Omori befriends Dr. Brief due to their scientific backgrounds.

By the time she became a teenager, Bulma's only dream in life was to find the perfect boyfriend and after finding the Two-Star Dragon Ball studied it learning of the legend of the seven magic Dragon Balls. After studying the mystical orb, she developed the Dragon Radar to track down the other six to wish for the perfect boyfriend. She briefly showed the Dragon Ball to Omori and Tights, theorizing they originated from outer space (which was partially correct as their creator Kami was originally from Namek though the Earth Dragon Balls themselves were created on Earth after King Piccolo was sealed away by Master Mutaito to give the Earthlings hope). During her quest, Bulma is confronted by Son Goku on Mount Paozu who mistook her for a witch and her car for a monster due to his unfamiliarity with technology due to being raised on Mount Paozu and having lost his memories of his life as Kakarot due to a head injury. After learning Bulma is an Earthling girl, he treats her kindly due to his deceased Grandfather teaching him to be nice to girls. After Goku refuses to part with his Grandfather's Four-Star Dragon Ball despite Bulma's attempt to bribe him with a panty flash which has no effect on the pure hearted Goku, she suggests he join her on her adventure while failing to tell him the Dragon Balls scatter after a wish is made. Though the two team up, Bulma has to deal with Goku who is unfamiliar with technology, females, and concepts like proper hygiene. However his immense strength proves useful in their quest. She also meets the desert bandit Yamcha whom she becomes smitten with unaware that Yamcha has a fear of girls and seeks to steal the Dragon Balls to rid himself of his fear. However he later teams up with Bulma's group to stop the Pilaf Gang and a mindless Great Ape Goku whom they realize is responsible for Grandpa Gohan's death unbeknownst to Goku who has no memory of his Great Ape transformations. The Pilaf Gang's plan is foiled and Goku after having his tail cut off decides to train under Master Roshi while he waits for the Dragon Balls to recharge. Meanwhile, Yamcha gets over his fear through interaction with Bulma and the two start dating after realizing they both have no more need for the Dragon Balls.

Bulma continued to support Goku and his friends providing her Dragon Radar and technological expertise to deal with threats to Earth's peace such as the Red Ribbon Army and King Piccolo's Demon Clan. For a time, she hoped to marry Yamcha after they develop a relationship but he became known for his promiscuity and she broke up with him by the time of Raditz's arrival on Earth in Age 761. Raditz interrupts Goku's reunion with Bulma, Krillin, Master Roshi, and Turtle's reunion at Kami House revealing his true identity as the Saiyan Kakarot though Goku refused to join his brother in invading planets due to his adoptive Grandfather's teachings. After Goku sacrificed his life to defeat his evil older brother, Bulma recovers Raditz's Scouter which she fixes allowing her to utilize it to read power levels. Vegeta arrives on Earth with Nappa in Age 762 seeking the Dragon Balls to acquire immortality but he is defeated by the Dragon Team after killing a crippled Nappa. She also supports the Dragon Team by repairing the Nameless Namek's Spaceship so they can go to Namek to revive Yamcha and the others killed fighting the Saibamen and Nappa.

By the time Bulma (29) and Vegeta (30) meet on Namek during the war with Frieza, Vegeta had already invaded Earth and fought the Dragon Team over the Dragon Balls but was left defeated and then betrayed Frieza as he decided to find the Namek Dragon Balls to gain immortality and kill Frieza. Because Vegeta was an enemy at the time, Bulma was scared of him. Ironically, Vegeta aided the Dragon Team unintentionally by killing Dodoria and Zarbon, as well as stealing the Namekian Dragon Balls from his Spaceship. Humorously, Bulma thought Zarbon was handsome and assumed he was there to save her from Vegeta until he transformed into his Monster Form and was killed by Vegeta, who spared Krillin and Bulma after they agreed to hand over the One-Star Namekian Dragon Ball, though Gohan found the Four-Star Ball that Vegeta hid and the arrival of the Ginyu Force forced Vegeta to join forces with the Dragon Team, though Bulma was left to survive on her own due to the urgency.

However, after Frieza's defeat, Bulma felt grateful to Vegeta for his help against Frieza and offered him to stay with her, though cheekily warned him to not to try anything naughty with her, causing Vegeta to call her a vulgar creature for saying something like that so loudly in front of Gohan and the Namekians. She was also thankful for his suggestion to wish to transport the souls of Krillin and Goku (believed dead at the time) to Earth before reviving them after King Kai explained that their souls would revive in space where Namek once was due to its destruction.

During the first two years of him living on Earth, Vegeta was baffled by Bulma's concern for him and tried to shrug it off as he interpreted it as pity. Despite Vegeta's rude behavior, Bulma tolerated him and her own temper often left Vegeta speechless and submissive. Four years after meeting Vegeta, she breaks up with Yamcha and Bulma attempts to befriend Vegeta as a source of comfort, which gradually causes them to develop a mutual attraction. Ultimately, Vegeta and Bulma succumb to their passion and begin an affair, and he impregnates her.

The birth of Trunks is a waking point for both of them; Vegeta is unable to accept his half-breed son and ignores the child whereas Bulma proves to be a doting mother who loves her son dearly. Over the next year, Vegeta ignores and neglects Bulma and Trunks but Bulma ignores this treatment as she is too occupied caring for Trunks. However, some of the Z Fighters can tell that Bulma still cares for Vegeta and she insists that Vegeta really does love Trunks despite how little it appeared.

During the three years of Training to confront the Androids, Vegeta had Dr. Brief construct an even more powerful Gravity Machine than the one Goku used. Additionally, Bulma would develop Battle Armor for Vegeta and the rest of the Dragon Team (though only Vegeta and Future Trunks would utilize it in battle outside of training). Eventually Vegeta would leave Earth briefly to train to achieve Super Saiyanhood like Goku, which he managed due to his anger at himself for failing to achieve it despite all his training. Though Vegeta believed he was pure evil when he achieved it, it is implied that his relationship with Bulma made him less ruthless which might have contributed to him acquiring enough S-Cells to transform as unbeknownst to Vegeta, the more gentle hearted a Saiyan is makes it easier for them to accumulate enough S-Cell required to transform (while Vegeta could still be a jerk and sought to return to his evil ways after proving himself Kakarot's superior, his relationship with Bulma shows he was slowly changing as he was willing to enter into a romantic/sexual relationship with an Earthling female despite being fully aware that Saiyans and Earthlings can produce hybrid offspring, something he had previously dismissed as he feared the potential of hybrids like Gohan only to ironically end up in a relationship with Bulma and fathering Trunks albeit his conception with unplanned).

Initially, Vegeta planned to leave Earth after the Androids conflict and the Cell Games because he never wanted to have children and saw Bulma and Trunks as burdens. However, after Cell is defeated, Vegeta and Bulma are able to reconcile for the sake of their child and they marry. They are able to form a genuine content and loving marriage, and Vegeta becomes civil with his in-laws, who accept him as part of the family. Seven years later, during the World Tournament Saga, Bulma becomes the new president of Capsule Corp., and expects Trunks to take over when he grows up. Vegeta takes it upon himself to train Trunks and teach him everything he knows. Although Vegeta gradually becomes a good father to Trunks and it becomes apparent that he loves Bulma, he secretly felt ashamed for settling down and giving up his warrior lifestyle for his family. In the Majin Buu Saga, Vegeta betrays his family to take advantage of the Majin Buu conflict to defeat Goku but he quickly regrets this as he finally realizes the importance of his family and was willing to die for them. Bulma was devastated by Vegeta's betrayal but then despaired when he sacrificed himself to try to kill Majin Buu, and then overjoyed when he was resurrected and teamed up with Goku to eliminate Majin Buu.

Four years later, Vegeta has become more family-orientated and embraced the Earth as his home. He and Bulma have developed a more loving relationship although Vegeta is still reluctant to take part in certain family activities. He also stops pressuring Trunks into training and gives him more freedom, which Bulma contributes to Vegeta growing soft with their son, but he is still strict with Trunks. Bulma however complains how Vegeta never contributes to the family but he retorts he trains hard to protect the family from future threats. During the God of Destruction Beerus Saga, Vegeta demonstrates his love for Bulma when she is hit by Beerus in retaliation for slapping him for ruining her birthday party, as seeing her hurt causes him to power up his Super Saiyan 2 form via Rage Mode and attack the God of Destruction in a fury, even managing to do better against Beerus than Goku as a Super Saiyan 3. However Beerus proves too powerful and he is defeated. After Goku acquires the Super Saiyan God form, Vegeta becomes obsessed with acquiring it. After learning that Bulma had befriended Whis who Vegeta discovers is Beerus' mentor, he convinces the Angel to train him. Bulma supports her husband's desire to get stronger by providing him with new Battle Armor. However she eventually reveals his training to Goku who convinces Whis to train him alongside Vegeta not wanting to fall behind, however this allows both Vegeta and Goku to achieve Super Saiyan Blue which proves invaluable during the Golden Frieza Saga and later sagas.

During the God of Destruction Beerus Saga, Trunks meets the age regressed Pilaf Gang becoming smitten with Mai as well as befriending Shu and Pilaf both who support Mai's relationship with Trunks. During the "Future" Trunks Saga, Vegeta and Bulma become aware of who Mai is after meeting Future Mai who is a young woman around Future Trunks' age due to being reduced to an infant when Future Trunks was still a baby himself. However Bulma is supportive of Future Trunks relationship with Future Mai even wondering about the possibility of them her grandchildren showing she has no problem with their relationship despite knowing Future Mai is much older than she appears. She is tolerant of Trunks' boyfriend-girlfriend relationship with Mai as she allows the Pilaf Gang to live at the Capsule Corporation though due to them being much younger than their counterparts, Mai and Trunks' relationship is more akin to childhood sweethearts. Additionally both Mai and Trunks' are shown to be attracted to each other's adult counterpart though after learning of their counterparts relationship, Mai gets over her infatuation with Future Trunks and turns her attention back to Trunks who was jealous of his counterpart though despite this encouraged Future Trunks to fight to protect Future Mai. Trunks is similarly protective of Mai.

Another year later, Bulma and Vegeta decide to have a second child and Vegeta makes it important for him to be there for Bulma throughout the pregnancy and birth. One month after Trunks' fourteenth birthday, Bulma gives birth to a girl named Bulla (beating Vegeta to the punch as he planned to give her the proper Saiyan name Ecshalot). Vegeta is swollen with love and pride for his daughter and dotes on her. Upon reaching adulthood, Trunks becomes the president of Capsule Corp. but strives to be only the high-class warrior he was trained to become since childhood.

In the future timeline from the "Future" Trunks Saga, Future Trunks is the last surviving member of the House of Vegeta and Brief family after Future Bulma is killed by Goku Black and her soul is erased by Future Zeno along with the souls of all his deceased family and friends. However his lover Future Mai survives the future Multiverse's erasure and with the blessing of Beerus, are allowed to relocate in a new timeline where Future Beerus and Future Shin's deaths were prevented and the Zamases' Project Zero Mortals was prevented, though they were forced to live alongside their counterparts within the new timeline though Future Bulma's counterpart is still alive in this timeline as a result of the Project Zero Mortals conflict being prevented.

By the year Age 880, the Brief family has only two known members, Bulma Leigh and her son, Vegeta Jr.. As shown by Pan's reaction to meeting Bulma Leigh and witnessing Vegeta Jr. fight with Goku Jr., it is implied that the Brief family and Son family are not as close as they were in the past, though this might change in the future as it is suggested that Vegeta Jr. and Goku Jr. might develop a close rivalry/friendship not unlike their namesakes Goku and Vegeta.

In Dragon Ball Online by Age 1000, Saiyan genes from Goku and Vegeta's descendants have been introduced into the Earthling population allowing Earthlings to achieve the Super Saiyan form by making a wish to Shenron, though all pure bloodied Saiyans have gone extinct by this point.

  • In the anime, due to switching bodies with Bulma, Captain Ginyu was technically a member of the Brief family until switching back to his Namekian Frog body. He also switched bodies with Vegeta and Future Trunks in the Xenoverse series.
  • The Bio-Android Cell contained cells from Vegeta, technically making him and his offspring members of the House of Vegeta.
  • The same could be said of Cell's fusions Celluza, Cell 17, Perfect 16, and Ultra Pinich.
  • Fake Vegeta is a duplicate of Vegeta made from Commeson.
  • As Android 21 contains the cells of Vegeta and Cell, she is also a member of the House of Vegeta as are her fissions Android 21 (Evil) and Android 21 (Good). It is unknown if Bulma and/or Dr. Brief's cells where among the cells of various scientists and scientific reseachers used in her creation as well.
  • The artifical clones of Vegeta, Future Trunks, and Cell created by Android 21 in Dragon Ball FighterZ can also technically be consider members of the Brief family and House of Vegeta as well for the same reason.
  • The playable Earthlings in Dragon Ball Online are descendants of Goku and Vegeta. The two martial artists from the Dragon Ball Online trailers are also descendants of Goku and Vegeta.
  • Leggings has the same naming scheme as the members of Bulma's family, heavily resembles Bulma, and also works for Capsule Corp. She supports Great Saiyaman 3 and his Dragon Ball Heroes team and like other members of the Brief family she is a brilliant scientist who invented the Hero Switch a bracelet that allows people to physically enter the SDBH game world by taking on the form of their Hero Avatar and even manifest the power of their Avatar in the real world.

Future Trunks' imaging a peaceful dinner with his mother and Future Mai

  • Future Mai is Future Trunks girlfriend who was also close to Future Bulma before her death and also consoled her boyfriend afterwords while reminding him not to lose hope and pushing him to flee to the past for help to the point of risking her own life. Future Mai like Future Trunks is also the only other mortal survivor of the erasure of the future Multiverse by Future Zeno thus the possibility exists that they could get married at some point in the new future timeline they relocated to. Bulma and Vegeta of the main timeline also seemed to have no problem with their relationship.
  • Mai is also Trunks girlfriend in the main timeline though compared to their counterparts' relationship the two are still young (Mai being a child due to a botched wish by Pilaf) thus a lot could happen between them before either reaches adolescence which could cause them to break-up or end their relationship. However they might stay together as they are both aware of their counterparts' relationship which Trunks' parents seem to have no objections to despite Bulma being aware of who Mai actually is and that Mai is far older than she physically appears. However in Dragon Ball GT, she is elderly and there is no sign of a relationship between her and Trunks, though it should be noted that GT is part of a different continuity to Dragon Ball Super.
  • Sho resembles Mai and was a Capsule Corporation scientist before joining Pilaf's descendant Paella's Paella Gang.

Team Attacks


  • 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.
  • In the Dragonball Evolution video game, Bulma's last name is Enchanto.
  • Aside from Vegeta’s career as an elite warrior, he possesses a tactical mind and extensive knowledge on technology, which ties him to Bulma and her family of scientists, who are all known for being highly intelligent and technical geniuses.
    • Vegeta is also inadvertently responsible for helping his wife and father-in-law develop technical devices, such as the spaceship pod and the Gravity Room, far advanced on Earth.
    • While Vegeta generally takes little interest in his wife's work, he is apparently security conscious about her lab's security as he notes in Dragon Ball Super: Broly that he told Bulma her lab needed better security measures after the Frieza Force break in, showing he is at least concerned with his wife's and Capsule Corporation's security.
    • Additionally his father King Vegeta has been noted by both King Kai and Dr. Lychee to have cleverness equal to that of a Tuffle. Thus one could say that Vegeta and King Vegeta could be considered the Saiyan equivalent of a genius.
  • Due to Vegeta being a legitimate prince, this would make Trunks a prince and Bulla a princess. Bulma also owns a cruise ship called the Princess Bulma which may be a tongue-in-cheek reference to her marriage to a prince.
