Bulma is the daughter of a famous scientist who invented capsules,
and is named after bloomers. Her family run the Capsule Corp and make other
useful inventions. This makes Bulma very smart. She started off the search
for the Dragon Balls when she found one in her attic. She found out all about
them and made a radar so she could look for them. She wanted to use the wish
so she could get herself a boyfriend. On her search she met Goku and he helped
her and let her borrow his Dragon Ball. She is around 4 years older than Goku
and is 16 at the start of DB. Bulma is an only child. She is outgoing and
stubborn, and her appearance means a lot to her. In the Dragon Ball series,
she would often show her panties to people (especially Muten Roshi) in return
for stuff.
From Dragon Ball to the start of DBZ Bulma was dating Yamcha, who changed
his looks almost as much as her. In the end they got bored of each other.
She went to Planet Namek with Krillin and Gohan to look for the Namekian Dragon
Balls. In the Android saga Bulma had a kid with Vegeta, called Trunks. At
the end of the series they had a daughter who was called Bra. Bulma is one
of the few people who can get Vegeta to do anything he doesn't want to.
