Bulma is a fictional character who first appears in the Dragon Ball manga created by Akira Toriyama, followed by an identical anime, including Dragon Ball Z and Dragon Ball GT. She was originally portrayed as a secondary main character, but her role was quickly downplayed as the series continued, even though she did still remain an important supporting character for most of the series. In the series, Bulma is the daughter of the Briefs family who own Capsule Corp., a fictional corporation that plays several roles in the universe and plot throughout Dragonball and its sequels. Being the daughter of a brilliant scientist, Bulma is also a scientist and inventor. Bulma is most credited for inventing the Dragon Radar, a device that is specifically designed to detect the signal emitted by the Dragon Balls in the series.
Bulma's father is Dr. Briefs, Bulma's mother is shown several times in the anime and manga, without an official name. Bulma's role as an inventor becomes important at several points in the series. Several of her creations were major to various plotlines, including a microband that could make her shrink, the time machine that brought Trunks to the past in the Android Saga of Dragon Ball Z and the generator that allowed Vegeta to achieve Super Saiyan 4 in Dragon Ball GT.
In Japan, Bulma was voiced by Hiromi Tsuru. Bulma is a direct parody of the character Xuanzang from the Chinese novel Journey to the West. Even though Bulma's character parodies a monk, her Japanese name "Buruma" is the brand of a popular gym short worn by girls in Japan. Her re-adapted name Bulma is a direct take on the word bloomers, which was a popular brand of women's underwear in the early 20th century.
