Bulma

Bulma is the resident genius. Her technological know-how is unsurpassed, and she is also the first one to search for the dragonballs. She meets Goku on her first journey, and the two remain friends. As the heir to the Capsule Corporation, Bulma is quite wealthy and spoiled as a result. She is fairly tempermental, but is actually quite caring. She may also seem like a coward at times, but she always finds a way to pull through.

She had a lengthy relationship with Yamcha before leaving him for unknown reasons, eventually pairing with Vegeta and having two children, Trunks and Bra, with the Saiyan prince.
