Bulma is the friend of Goku who convinced him to go in an exploration to search for the dragon balls. Bulma was born to a rich family, with his father owning Capsule Corporation.
Bulma is also obsessed with finding the love of her life. Her primary motivation for the dragon balls is to use it to find the man for her. At the end, she became the wife of Vegeta and they had two children.
But beauty and love are not all that Bulma is about. She was always curious about science and technology and wanted to learn everything there was to know about it. Her inventions were a great help in finding the dragon balls.
