Directory: CharactersHumansZ Fighters support Dr. Brief (ブリーフ博士, Burīfu Hakase) is an elderly, brilliant and eccentric scientist. He is the founder of Capsule Corporation, father of Tights and Bulma, and grandfather of Trunks and Bulla. Dr. Brief is also one of the smartest and richest men in the world. He lives in West City with his wife and their many pets.



Art of Dr. Brief by Akira Toriyama

He is a short, stocky man. His hair is very similar to that of his daughter, but is gray/blue instead of green. He also has a large gray mustache. He dons a white lab coat with a blue undershirt, and black pants. He is almost always seen smoking a cigarette, and wears large glasses.


Dr. Brief is easy-going and friendly. He rarely leaves his home, even if it means almost certain death; in the Majin Buu Saga, he and his wife, Panchy, refuse to leave their pets even after Capsule Corporation has been specifically targeted for destruction. This is probably due to the fact that they know they can always be wished back with the Dragon Balls. He can often be found tinkering on a number of complicated gadgets while surrounded by his beloved pets. His favorite pet is a small black cat named Scratch (or Tama, in Japanese), which usually is perched on his shoulder. In the early Dragon Ball series, Dr. Brief was depicted as a little bit of a pervert when Bulma tried a capsule and dirty magazines were in the contents, with Bulma being very angered with her father for this, and Goku, not realizing what the magazines actually were, pitied the girls because he thought they were too poor to even afford clothes. In Dragon Ball Z: Battle of Gods, it is shown that neither he nor his wife were aware that he was the richest man in the world until they overheard Chi-Chi point that fact out to Mr. Satan after he mistook Dr. Brief for one of the catering staff at Bulma's Birthday party, showing he is apparently ignorant of his own wealth.

His ignorance of his absurd wealth can be attributed to his love of his lifestyle, which revolves mostly around his various experiments and other engineering projects, tending to his expansive menagerie of common and exotic pets, and general puttering about his home.

Dr. Brief's amicability allows him to deal with his son-in-law's antics and rage without much surprise or fear, though he has cautioned Vegeta against overtaxing his body in enhanced gravity on at least one occasion.

He also has no problem with providing technology for Trunks and Vegeta to train in enhanced g-forces, gladly developing technology for whatever purposes his family finds for it.

Dr. Brief's ability to take extraordinary events in stride such as the threat of Cell, Vegeta's angry and threatening demeanor, and ability to create faster-than-light speed engines in a matter of days may simply be due to his immense intelligence, with his almost superhuman brain power allowing him to adapt to these stressful situations with little wear and tear on his sanity. However, it may just be due to his chain smoking that he copes with these events in his life.

Dr. Brief graduated from the West City College department of science and engineering. He completed his doctorate in the department of science and engineering graduate program at that same college. His major was physical science. He established Capsule Corporation after his invention of the revolutionary item, the Dynocaps Capsule. Until Dragon Ball GT, he is the representative director and president of his company.

Main article: Dragon Ball Z: Battle of Gods Four years after the defeat of Kid Buu, Dr. Brief is at Capsule Corporation celebrating Bulma's birthday party. Dr. Brief was asked to get Mr. Satan another drink due to Mr. Satan mistaking him for one of the catering staff, which was not helped by Dr. Brief's carefree reaction to Mr. Satan's request. It was only when Ox-King informed Mr. Satan that he was Bulma's father, Dr. Brief, did Mr. Satan realize who he was, causing Mr. Satan to literally fall out of his chair, due to realizing he had just insulted the greatest genius in the world. Chi-Chi then tells Mr. Satan that Dr. Brief is also the richest man in the world, a fact which apparently neither Dr. Brief or his wife were aware of. Upon realizing his mistake Mr. Satan tried desperately to apologize for being rude, even though Dr. Brief was not offended and even offered to fulfill Mr. Satan's request of a drink, Mr. Satan insisted on bringing Dr. Brief's a drink instead to apologize for his rudeness, so Dr. Brief asked for a cola, causing Mr. Satan to run off saying that he would bring Dr. Brief a whole case of cola.

Dr. Brief in a pond

Dr. Brief reunites with Jaco inside Capsule Corporation and offers him to see his gold-fish. Outside, Dr. Brief and Jaco are relaxing by the pond while Jaco is feeding the gold-fish. Eventually, Jaco realizes that playing with the gold-fish was wasting his time and he needs to speak with Bulma. After Dr. Brief gets Bulma, they are informed that Frieza has been revived and is heading to Earth for revenge. After Jaco walks off because he doesn't want to encounter Frieza, Bulma follows and accidentally knocks Dr. Brief into the pond.

Power level

In Dragon Ball Z: The Anime Adventure Game, Dr. Brief's power level is 12.

In spite of his average power level, Dr. Brief is among the most intelligent humans in existence, able to engineer the Dynocaps Capsule technology, keep up with the sophistication behind Dr. Gero's androids, and run a multi billion zeni corporation. He is also most certainly from where Bulma got her superhuman intellect, as well as his grandson's talent and interest in science and engineering.

He appears to be knowledgeable regarding Saiyan biology, as he built the gravity chambers that Goku and Vegeta have utilized in their training, as he would not otherwise build such dangerous technology if he was not aware of how Saiyan physiology would allow them to survive such extreme conditions. Given his extraordinary intellect, it would be reasonable to assume he has since amassed a good deal of knowledge regarding the Saiyans, as many of them are among his closest friends and relatives.

Techniques & Inventions

  • Hero's Pose - In one of the endings of Dragon Ball Super, Dr. Briefs performs Jaco's signature Fighting Pose alongside his wife and eldest daughter, Tights.
  • Capsules - Dr. Brief's revolutionary invention that lead to the establishment of the Capsule Corporation which allows people to store various objects from weapons, vehicles, and even houses.
    • Capsule House - A type of house specially designed to be stored inside a capsule that are can cost at least half a million Zeni.
    • Capsule Corporation spaceship - A Spaceship originally developed by Dr. Briefs for Goku from pieces he had salvaged from the remains of the Attack Ball that originally brought Goku to Earth. Using knowledge he had recently obtained from helping Bulma repair the Nameless Namek's spaceship and what remained of Goku's Attack Ball, Dr. Briefs was able to create a Spaceship capable of reaching Namek in six days time (outclassing any Earth-based spaceship at that time ) and durable enough to endure all the abuse it took during Goku's Gravity training inside the Spaceship. Though the original ship was later destroyed along with Planet Namek, Dr. Briefs managed to replicate the technology very quickly allowing his company to produce at least two more models of nearly identical design.
      • Gravity Machine - Originally created by Dr. Brief for Goku to allow him to train during his six day journey to Planet Namek. The original machine was capable of simulating the 100 times the Earth's gravity, allowing Goku to reach a power level of 180,000 via the 2x Kaio-ken (surpassing even the mighty Captain Ginyu). This machine was later destroyed along with the Capsule Corporation Spaceship when Namek exploded. During the Trunks Saga, Dr. Briefs created an improved model at the insistence of his future son-in-law Vegeta in order to train to become Super Saiyan to prepare for the coming Android conflict, which was capable simulating 500 times Earth's gravity.
    • Golden Capsules - A highly experimental capsule created by Dr. Brief in The Legacy of Goku II that can transport the user to the World Map if used in a city or wasteland. Dr. Brief ends up dropping 25 of these capsules while conducting atmospheric experiments and asks the Z Fighters to find them, allowing them to keep one if they manage to find all of them.
