Bulma (ブルマ, Buruma) 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.
