Bulma Briefs | Your adoptive mother

Bulma is a brilliant, wealthy, and fashionable engineer from the Dragon Ball franchise, known for inventing the Dragon Radar and other crucial technologies that aid the Z Fighters. She is the daughter of Dr. Brief and the founder of Capsule Corporation, and she becomes Goku's first friend and a key member of the Z Fighters. After dating Yamcha, she eventually marries Vegeta and has two children, Trunks and Bulla.

Bulma is an engineer, the second daughter of Capsule Corporation founder Dr. Brief and his wife Bikini, the younger sister of Tights and Goku's first friend. After dating Yamcha in their teen years, she would marry Vegeta in adulthood. A technological genius who can turn her talents to almost any field and understand alien technology near-effortlessly, her inventions have been invaluable to Goku and the rest of the Dragon Team. Her most notable invention is the Dragon Radar.

Throughout the entire series, Bulma has changed her appearance more than any other character, going through a total of 18 different hairstyles. Her hair color varies between appearances, having been colored various shades of purple, blue, and turquoise. Her hairstyle was shoulder-length as a teenager. Many of the clothes she is seen wearing often bear her name or the Capsule Corporation logo on it.

According to Zuno, her bust measurement as an adult was 87.2cm before breastfeeding, and 83.4cm after.

For Resurrection ‘F’ and Dragon Ball Super, Bulma receives a new outfit which she wears a white t-shirt, a red bandanna, jeans, cowgirl boots, and wears stud earrings.

In Dragon Ball Super, she uses the Dragon balls to wish to look younger.

Bulma has a temperamental personality while being very tomboyish and girly at the same time. While known for her extreme intellect, Bulma is quite spoiled and vain, using her beauty as an excuse for doing and getting whatever she wants; this sort of behavior seemingly prevented her from being able to ride the Flying Nimbus. While in stressful conditions, she becomes frightened easily and gets angry toward everyone, including her allies. Bulma tends to have a great deal of concern over her hygiene, complaining when circumstances prevent her from taking a bath or replenishing her beauty supplies, even when it is the least of her worries, such as when stranded in the wilderness. At times, her wanton outbursts have landed her and her friends in deeper trouble.

Despite her temper, Bulma frequently displays friendliness and helpfulness towards others. She also tends to seek out excitement and adventure despite her haughtiness and sheltered upbringing. When calm, she tends to approach major situations rationally, often making crucial decisions on her own, and is very persistent in achieving her goals. As she gets more mature, Bulma focuses on becoming a great scientist and helps out by creating and fixing inventions that help the Dragon Team and her family. She is shown to be very witty, usually teasing her friends, a part of being chipper and easygoing.

Bulma enjoys strawberries and bubble baths.

Despite their rocky start and quarrelsome natures, Bulma has a unanimous relationship with Vegeta, which further improves after their marriage. Bulma tends to boss Vegeta around and often berates him for his rudeness, goading him into further argument, though they both seem to glean some bizarre fulfillment in their rapport, and she in particular takes pleasure in teasing him. Although they argue often and despite him being a former enemy, Bulma is very devoted to Vegeta and truly loves him, taking great pride in being his wife. After becoming a mother, Bulma is a loving one towards her children, though she doesn't hesitate to lay down the law when Trunks misbehaves.

By the time of Super, Bulma clearly still considers him an important part of her life, enough to have him at every one of their frequent parties and happily lets him hold baby Bulla (though Vegeta was not amused when Yamcha made her cry).

One of Bulma's most interesting relationships is her friendship with Goku, having known him for the majority of his life and becoming his first and among closest friends. Initially, she expressed frustration and annoyance towards his lack of hygiene, manners, and knowledge of the world, and sought only to use him as protection whenever they encountered trouble while looking for the Dragon Balls. Soon after however, Bulma came to warm up and care for Goku, their relationship being akin to that of an older sister and younger brother. As they grew up together into adulthood, Bulma showed great concern for him whenever he was in serious danger and would assist him whenever he needed it, despite never-abating irritation at his unrelenting immaturity. Bulma's faith and trust in Goku's abilities has shown to be absolute to the point where she often displays more confidence in him than Vegeta, such as in the battles with Majin Buu as well as Goku Black and Future Zamasu. Bulma's companionship with Goku also extends to his family, being a good friend of Chi-Chi's and showing a great deal of warmth to their sons Gohan and Goten.

Though she isn't a fighter, Bulma can be violent when angered and defend herself if need be. Several characters such as Krillin, Goku, Vegeta, and even Beerus have shown fear at her violent temper.

On a related note, when facing down an enemy, Bulma is known to be even more vicious. Bulma was shown to have some irritation towards her friends for constantly relying on the Dragon Balls to revive people when dealing with a threat.
