Bulma

Bulma (Romaji: Buruma, full name commonly accepted as Bulma Briefs) is a fictional Human who is the Dragonball series's longest appearing female character. As common in the Dragon Ball universe, names in her family are based on themed objects (also useful as a mnemonic device), specifically types of pants. Bulma refers to bloomers (buruma), the traditional gym shorts worn by Japanese schoolgirls.

In the early Harmony Gold English Dragon Ball dub from the 1980's, she is known as Lena.

Bulma is the second (after Son Goku) character to be introduced in the series. In the early part of the plot, she is the one that has invented a Dragon Radar and is searching for the legendary Dragon Balls. She finds that Goku inherited one of the balls (the four-star ball) from his Grandpa Gohan. At that point, they team up to find the remainder of the balls and the adventure begins. As the anime progresses, Bulma's role waxes and wanes. In the later action-oriented episodes of the series, there is little room for a genius but Bulma continues to play a role as a secondary character.

Bulma is well known for her intellectual approach to situations. She is also very proud of her abilities and can be very cantakerous when slighted, which may indicate a similar approach with other men. Bulma's first relationship in the series was with Yamcha, but after the Freeza Saga she has a relationship with Vegeta which leads to the birth of Trunks.

Bulma's father is Dr. Briefs, but it is unclear in the manga whether 'Briefs' is his first name or his last. Bulma's mother is shown several times in anime and manga, but she is never given an official name.

Bulma's notable inventions besides the Dragon Radar, include: modified Saiyan Armor for the hyperbolic time chamber, A Blutz Wave generator to allow Vegeta to reach Super Saiyan 4, and a time machine to allow Mirai Trunks to get to the past. She also repairs Android 16 with her Father.
