Bulma

Bulma (ブルマ, Buruma) is one of the central and longest-running characters in the Dragon Ball anime, starting as Goku's first human friend and companion in the original series.

She's a brilliant teenage (later adult) scientist and inventor from a wealthy family, the daughter of Dr. Brief, founder of Capsule Corporation. Bulma is a technological genius capable of creating advanced devices — most famously the Dragon Radar to locate the Dragon Balls — and she frequently adapts or reverse-engineers alien tech with ease. Her inventions play a key role in supporting Goku and the other fighters throughout the series.

In terms of personality, Bulma is intelligent, resourceful, and confident, but also quite spoiled, vain, temperamental, and materialistic (especially early on). She's tomboyish in some ways yet very girly and beauty-conscious, often using her attractiveness and charm to get what she wants. She can be bossy, sarcastic, and quick to complain about danger or discomfort, but she shows genuine loyalty, courage, and care for her friends over time.

Physically, in the anime she's typically depicted with turquoise/blue hair (often in varying styles like ponytails or loose), fair skin, and a curvy figure, frequently wearing fashionable or practical outfits that highlight her role as a non-fighter in a combat-heavy world.

She evolves from a boy-crazy adventurer seeking the perfect boyfriend via the Dragon Balls into a key ally, eventual wife of Vegeta, and mother to Trunks and Bulla in later arcs.
