Background / History

Bulma first encounters Raditz after Krillin mistakes him for a Red Ribbon Army member and badly injures him. She checks that he is still alive, reprimands Krillin for attacking prematurely, and argues that Raditz should be treated rather than abandoned. She later invites him to stay at Kame House, reasoning that the group can protect one another from Dr. Gero. 2

After learning that Dr. Gero modified Raditz, Bulma takes him to her family home in West City so Dr. Brief can examine him. She supports the investigation into the controller left in his body and helps Raditz after his Saiyan genes awaken and hunger causes him to collapse. 6

Bulma accompanies Raditz in searching for Goku's buried spaceship and becomes deeply interested in its technology. She deciphers the alien Scouter's language system within a day, enabling Raditz to use it safely. The recovered spacecraft also provides the technological basis for the Brief family's Gravity Chamber. 8 9

She allows Raditz to stay at her home while he trains, monitors his condition during his early gravity training, and later spends a month with him while he recovers before the World Martial Arts Tournament. 14 16 She supports him from the stands during his match against Tien Shinhan, though she is frustrated when he later forfeits rather than pursuing the tournament title. 18 20

When King Piccolo's attack leaves Goku and Krillin missing or dead, Bulma contributes practical solutions, including a new Dragon Radar and arranging for Krillin's body to be preserved in a cryo-capsule. 22 After learning that Dr. Gero has surveilled the Brief residence, she immediately begins building an Interferer to disrupt abnormal signals. 34

Bulma and Raditz become an official couple before he departs Earth to train in space. His unexplained departure leaves her angry and hurt, particularly because he does not say when he will return. 36 37 Once Raditz settles on Namek, the two maintain daily communications. Bulma ultimately uses Earth's Dragon Balls to teleport herself, Krillin, Tien Shinhan, Yamcha, and Chiaotzu to Namek to reunite with him. 47 48

On Namek, Bulma joins Raditz in gathering Dragon Balls, explores the planet with him, and helps establish the Earth group’s temporary living arrangements using Hoi-Poi Capsules. 48 49 She later supports Raditz's decision to remain on Namek for further growth, despite their temporary separation. 50

Following Turles's attack on Earth, Bulma again modifies the Gravity Chamber for Raditz and Goku's future training. During the work, she and Raditz spend several quiet days together at her home, strengthening their relationship. 78 79

Appearance

Bulma is described as a bright, beautiful girl with blue hair. By Raditz's later return from Kami's Lookout, she is visibly shorter than his taller, more muscular adult frame. 2 32 37

• Blue-haired. 37
• Often works in a laboratory wearing tied-back hair, a lab coat, protective goggles, and practical research attire. 79
• Comes from the wealthy Brief family of West City and lives at the Capsule Corp estate. 6 32

Personality

Bulma is direct, outspoken, and quick to act when she sees someone being treated unfairly. She scolds Krillin for attacking Raditz without listening and openly rebukes Master Roshi for his inappropriate behavior. 2

She is highly curious about unfamiliar technology and readily devotes herself to research, whether studying an alien spacecraft, improving a Gravity Chamber, or creating defenses against Dr. Gero's surveillance. 8 9 34 79 Her blunt manner remains intact even with Raditz; she questions his decisions, teases him, and makes her displeasure clear when he prioritizes training or leaves without warning. 16 32 36 79

Despite this sharpness, Bulma is compassionate and loyal. She worries about Goku and Krillin during King Piccolo's crisis, supports Raditz's dangerous training, and travels across space to Namek to see him. 14 22 48
