Bulma appeared at the very beginning of dragon ball. She ran into goku at the start of the series. Bulma has since then alinged herself with Goku. In DB she, along with Goku, searched for the dragon balls. Later in DBZ, we find that Bulma's father, Dr. Briefs, is head of a company known as capsule corp. Bulma is his asssintant as they begin to invent many things. Bulma, like Chi Chi, adds some comic releaf to the series. In the Freeza saga, when she goes along with Kurririn and gohan in search of the namekian dragonballs, we always find her trying to be in charge and bossy. However, when something bad happens, she constantly freaks out. As the series of DBZ progresses, you will find that Bulma goes through many hair changes. She also becomes head of the capsule corp and matures a bit. Early in the Cell Game, we find out that Bulma and Vegita had a baby named Trunks. Through the Cell series, she took care of trunks. In the Buu series, Trunks gets older and Bulma begins to give him a little more freedom.
