Bulma
Bulma is Goku's first buddy and the second daughter of Capsule Corporation's founder Dr. Brief and his wife Bikini, the younger sister of Tights. She was Yamcha's girlfriend before moving on and eventually becoming Vegeta's wife as well as Trunks and Bulla's mother. Bulma is the series' most important female character. Aside from Goku, Bulma is the longest-running character in the entire meta-series, appearing in the first Dragon Ball chapter and episode and remaining prominent until the end.
Bulma has a volatile personality that is both tomboys and girly at the same time. Bulma is known for her extraordinary intelligence, but she is also spoiled and egotistical, using her wonderful attractiveness to justify her selfish actions. Bulma is a very caring mother to her son and daughter after becoming a mother, even if she displayed some recklessness when she took Trunks to the Androids battlefield while he was a baby, but she subsequently learns from this error.
Despite her good traits, she places too much focus on her appearance, which may be one of the reasons why the Nimbus Cloud refused to let her ride on it. As she grew older, she became so concerned about losing her beauty that she went so far as to acquire the Dragon Balls just to look 5 years younger.
