Bulma is the daughter of a scientist
named Dr.Briefs and so grows up at the Capsule Corp. learning how to
become a mechanical genius. She can operate and fix practically anything
you could think of! She is a key character to Dragonball Z, for example
persuading Goku to look for the Dragonballs with her (right at the start!)
At first she seems really mixed up
and short tempered but later she seems to settle down a bit better. She is
very determined and never gives up (although on Namek very close to it) At
first Bulma loves Yamcha, but later gets closer to Vegeta which leads to
them (Bulma and Vegeta) having a son called Trunks.
